Dear friends, we will have our annual Epiphany potluck luncheon on Sunday February 5 at 12:15 pm, immediately after midday office which begins at 12:05 pm. Please feel free to bring friends. The more, the merrier. We give thanks to God for all good things, most especially the gift of friendship. with love to you all…
Message from David Alexander: Our next book selection is Beauty for Truth’s Sake: On the Re-enchantment of Stratford Caldecott. I want to suggest everyone procure their copy and we meet for the first discussion on 1/25/2017. The reading for the discussion is the Introduction and the first chapter, pgs. 11- 36.
The book is short, about 150 pages. We could either meet once a month and cover two chapters per session or meet every two to three weeks and cover one chapter of the six chapters per session, whichever you would prefer. Perhaps it will be easier to decide after our first reading, judging from the content.
As a qualification on how we are to understand judgment in Aristotle, please note that, in the kind of analysis which we find in Aristotle and also in the manner of his conceptualization and language, in our acts of judgment thus, a dual nature is distinguished or two natures are indicated in a way which seems to juxtapose one nature with another. Two natures exist instead of one nature. A synthetic, constructive element is alluded to, on the one hand, and, on the other hand, an affirmative, declarative element. Hence, questions exist (later questions were posed) which asked if Aristotle was successful in clearly distinguishing between the being of these two different aspects (existing as two distinct elements, each having its own distinct nature).1 Did he, in fact, clearly distinguish between acts of direct understanding and acts of reflective understanding which exist as acts of judgment since, in Aristotle, judgment engages in two different kinds of tasks. On the one hand, allegedly within our judgments, (1) a composition or a putting together of different concepts occurs or, on the other hand, a separation of concepts when we realize that some concepts should not be combined or joined with each other. If an act of direct understanding (which, as noted, Aristotle conceptualizes as an act of “simple apprehension”) moves through the instrumentality of an imagined fertile, apt image (existing as a phantasm) toward a single, distinct concept or a definition which expresses the fruit or the grasp of one’s prior act of understanding (in Aristotle’s understanding of the nature or the intelligibility of all our direct acts of understanding as we move from the being and the order of sense to the order and the being of understanding: ta men oun eidê to noêtikon en tois phantasmasi noei; the “intellect grasps forms in images”),2 a fortiori, if we should speak in this way about the being of a “simple apprehension,” then, to a greater degree, if we are to speak about how two or more concepts can be put together to reveal a greater unity or a link that exists between these concepts (leading to a larger, more general concept), then, in order to identify and to distinguish this species of intellectual act, we should or we must speak about the being of a “complex apprehension.” These exist allegedly as judgments. These judgments introduce an order which should exist among our ideas and concepts. However, if, for us, the intellectual object is not simply the apprehension of a conceptual complex unity but if, in fact, it is an understanding which wants to declare or know about the reality or the truth of one or more concepts (whether we should speak about simple concepts or about complex concepts), then, within this larger, greater, more demanding context, in Aristotle, a second understanding of judgment presents itself to us in terms of how it seeks to posit a relation or a synthesis which has been grasped by us in our prior acts of understanding. The object here is not essentially a synthesis, the apprehension or the grasp of a synthesis which points to a higher or a wider understanding of things but, instead, the taking of an already understood synthesis and further acts which would work toward an act of understanding which can conclude or move toward a declaration of its reality or a declaration of its truth (or which can deny the factuality of its reality or the factuality of its truth). This is so. This is not so. Either way, in affirmation or negation, a truth is known and it is grasped by us as known. In our awareness, a truth is known in terms of its reasonableness or cogency: hence, its being, its reality. The consciousness or experience that we have of evidence points to the being or the reality of a truth and, as an effect which would thus follow from this, with Aquinas, we would say about ourselves that “knowledge exists as one of the effects of truth” [cognitio est quidam veritatis effectus].3 The one comes from the other.
In Aristotle thus, depending on which passages or texts are being studied, a clear distinction does not exist between that which exists as understanding and that which exists as judgment (acts of direct understanding versus acts of reflective understanding) because judgment, in the language of “composition and division,” resembles acts of direct understanding in terms of the unities which are being grasped and understood by them (by our acts of understanding): unities which transcend pluralities and multiplicities as these exist initially among the givens of the data of our sense perception. However, in Aristotle, the being of judgments is such that they also seek to determine if a correspondence exists between that which exists as a form of mental synthesis within ourselves and that which exists as a species of real synthesis within the being of truly existing things (the being of truly existing objects). A real distinction accordingly exists between the type of answer that is given to this kind of question and the type of answer which is given to a question which asks about how concepts can be related to each other in ways that could lead to the understanding and eventually the expression of a new, more general concept.
On the basis then of this real distinction and as a species of new first principle, in the later work of Aquinas and also in the later work of Bernard Lonergan, clarifications were introduced into the thinking and the conceptuality of Aristotle’s analysis in a manner which attempted to introduce degrees of clarity that had not been too obvious to anyone or to most persons who had attempted earlier to read into the corpus of Aristotle’s philosophy in order to find, within it, a coherent understanding about how things exist within the reality of the world within which we all live (a reality which includes the kind of being which we have and which we are as human beings where our kind of being includes the kind of knowing which belongs to us as human beings and which does not belong to other kinds of living being). From an incoherent understanding about the nature of our human judgment (from an incoherent understanding about the nature of our human cognition), we can thus wonder if, for some in the subsequent history of reflection within philosophy, the result has been a defective, incoherent understanding about the nature of existing things where, in metaphysics, we turn to this science in order to move toward a comprehensive or a general understanding about the nature of all existing things qua the nature of being in general as it applies to all things which enjoy some form of real existence. What can be implied about the nature of our world if our point of departure is a particular belief or a particular understanding about the nature of our human knowing, an understanding which could be lacking in the degree of rationality which should belong to it?4

ST 1.84.1 Does the soul know bodies through the intellect
Objection 1: Bodies are understood by the senses, incorporeals by the intellect
Reply: This refers to the medium of knowledge, not the object
Objection 2: Sense:Intelligible :: Intellect:Sensible. Since senses can’t understand intelligible things, the intellect can’t understand sensible things
Reply: Intellect is a higher power than sense. While sense cannot know intelligibles, intellect can know sensibles. Otherwise God wouldn’t have knowledge of sensibles.
Objection 3: Intellect understands eternal and unchangeable things, while bodies are always changing
Reply: Every movement presupposes something immovable. Changing form requires unchanging matter. Changing matter requires unchanging form. Socrates may not always be sitting, but it is always true that when he does sit he stays in one place.
On the contrary: natural science, with its studies of motion and matter, would be impossible if the intellect had no knowledge of changeable things.
One possible answer: Certain Presocratics (Heraclitus) thought everything was in a state of flux, so certain knowledge of anything was impossible.
Refutation: Heraclitus was only led to this conclusion because of their reductive materialism.
Another possible answer: Plato’s theory of forms
- If forms are immaterial and immovable, how can we have knowledge of matter and motion?
- Plato begs the question: How can we know bodies, if we only know them through separate substances which differ essentially from them?
- Plato assumed that the form must exist in the knower in the same mode as in the thing known. This is not true.
Whiteness is in bodies in different modes of intensity
The senses receive whiteness without receiving matter
The intellect receives whiteness under conditions of immateriality and immobility
ST 1.84.2 Does the soul know bodies through its essence?
It would seem so. Knowledge is by assimilation, where the intellect “becomes” whatever essence it is to know. Thus, the intellect knows all things by the essence it has assimilated, which essence has become the intellect’s own essence.
But Augustine says we know things through our senses.
Presocratic view: the material intellect receives forms materially
- Matter is only form potentially, and knowledge is of actualized form
- Why doesn’t matter outside the soul possess knowledge?
Platonist view: The immaterial soul receives forms immaterially
Only God knows things through his own essence; humans and angels don’t
ST 1.84.3 Does the soul know through innate species?
Our knowledge is different from angelic knowledge. Our knowledge must be brought into act, while angelic knowledge is always in act. Moreover, the angelic intellect is completed by the angelic form and is not in potentiality with respect to anything. The human intellect is in potentiality with respect to things it does not know. Prime matter is in potentiality with respect to its substantial form.
ST 1.84.4 Are intelligible species derived by the soul from separate forms?
The objections proceed by analogy from sense, also noting that the intellect requires something actually intelligible in order to be brought into act.
But if we know by separate forms, there is no reason why our souls should be united to bodies. Both Plato and Avicenna’s views are considered and deemed insufficient for explaining the existence of the body.
In replying to the objections, St. Thomas says there is no analogy between sense and intellect. He concedes that divine ideas are the ultimate source of our knowledge, but we attain to this knowledge by the actualization of phantasms by agent intellect.
ST 1.84.5 Does the intellect know material things in the eternal types?
St. Thomas states that Augustine was “imbued with the doctrines of the Platonists.”
St. Thomas makes a distinction:
- Knowing the eternal types as objects. The souls of the blessed know things in the eternal types in this way.
- Having the eternal types as a principle of knowledge. Just as our senses see by the light of the sun, our intellect sees by the intellectual light which is in us, even as pilgrims.
The human intellect requires both intelligible species and intellectual light in order to know.
St. Thomas shows that Augustine was not as Platonist as he originally seemed.
ST 1.84.6 Is intellectual knowledge derived from sensible things?
Augustine’s argument that intellectual knowledge does not come from the senses
- Sensible things are always changing, but what is never the same cannot be perceived
- We cannot tell through the senses whether we are seeing a real image or whether we are seeing an imaginary image (dreaming), but the intellect is capable of perceiving truth
- What is lesser cannot act on what is greater, so the senses cannot produce knowledge in the intellect
- We know some immaterial things
Democritus thought all knowledge was by a discharge of atoms
Plato thought the soul forms within itself the species, after the sensible organ receives the sensible object. The soul is roused by the species of the thing.
Augustine said the body was the messenger to the soul.
The senses rouse the intellect to the act of understanding.
Aristotle said sense is an act not of the soul alone, but of the “composite.” The sensible is received in the sense by a discharge or some other operation. Then agent intellect derives the phantasm and ultimately the intelligible species from the sensory input.
Sensible things are only the material cause of knowledge. Agent intellect is also required.
ST 1.84.7 Can we understand without turning to phantasm?
- When imagination is hindered by frenzy or lethargy, all intellectual operation is also hindered.
- We all understand by forming phantasms to serve as examples
- It belongs to a nature to exist in an individual. This cannot happen apart from corporeal matter. Since we apprehend the individual through phantasm, we need phantasm in order to see the universal nature existing in the individual.
When knowledge is not actualized, intelligible species dwell in the passive intellect.
The intelligible species is NOT the likeness of the individual thing.
Our intellect’s proper and proportionate object is the nature of a sensible thing (?)
ST 1.85.1: Does our intellect understand corporeal and material things by abstaction from phantasm?
3 grades of cognitive powers:
- Sense organ: object is form existing in individual matter
- Human intellect: object is form existing in individual matter, but not AS existing in this particular matter
- Angelic intellect: object is form existing apart from matter
2 types of abstractions
- Composition or division, i. e. Judgement of truth or falsehood
- Simple or absolute consideration: consider something and prescind from its principles of individuation
3 types of matter:
- Individual (“this flesh and these bones”)
- Common/signate (“flesh and bones”)
- Common intelligible matter (quantity, number, dimension, figure)
(things like “being,” “unity,” “power,” “act” abstracted from all matter)
“The phantasms are made more fit for the abstraction therefrom by intelligible intentions.”
ST 1.85.2: Are intelligible species the object of our intellection?
No, intelligible species are the species qua, not species quae intelligitur.
Otherwise, science would be about words, not things.
Also, we would have no way of judging the truth or falsity of our ideas.
Intelligible species is a likeness of the thing understood, as heat in the heater is a likeness of the thing heated
Abstract universal exists in the mind, but the universal which is understood exists in its instantiations.
2 operations of the sensitive part:
- Impression (totally passive)
- Formation (imagination, active)
2 operations of the intellect
- Impression (passive intellect receives intelligible species)
- Formation (active intellect forms definition or judgement)
ST 1.85.3 Whether knowledge of the most universal species is prior?
Sense knowledge is prior to intellectual knowledge. Therefore in some manner we know the particular first.
However, in the intellect we know what animals are, albeit indistinctly, before we can distinguish rational animals from non-rational animals.
In the senses, we know something is a body before it gets close enough to be known as an animal. A child calls all men father before he learns to distinguish his father. Therefore, universal sense knowledge is prior.
Something’s genus is derived from its common matter; the species comes from the form. Nature ultimately intends the species, not the genus.
ST 1.85.4 Whether we can understand multiple things at once?
No, just as an object cannot have multiple colors at once, an intellect cannot have multiple intelligible species at once
We can, however, understand multiple things in a single species
ST 1.85.5 Whether our intellect understands by composition and division?
Yes, because our intellects achieve perfection by degrees. We must make a judgement (i. E. a composition or division) about the state of our knowledge in order to attain more perfect knowledge.
Intellectual operations are in time insofar as we have to turn to phantasms
2 types of composition in a material thing
- Form with individual matter: Man is an animal (form with common matter); Socrates is a man (individual matter with form)
- Substance with accident: Socrates is white (Socrates as a man possessing whiteness)
2 types of composition in the intellect
- The whole with the part (form/species with common matter/genus)
- Subject predicated of accident (identification of Socrates with whiteness)
ST 1.86.6 Can the intellect be false?
The intellectual light cannot err, because the proper object of intellect is the quiddity of the thing. Provided we are abstracting quiddities from phantasm or deriving first principles from the operation of the intellect itself, the intellect cannot be false.
In composition or division, the intellect can err.
ST 1.86.7 Can one man understand better than another?
- No, in the sense that all men understand through the same intelligible species. Either you have the intelligible species or you don’t.
- Yes, in the sense that one man may perceive the intelligible species with greater keenness than another, as a man with 20-20 vision will see visible objects better than another.
- Yes, in the sense that intellect’s operation depends on the sensitive and imaginative faculties. Someone with a better memory, for instance, can understand things better.
ST 1.86.8 Is the indivisible known before the divisible?
- Yes, in the sense that we know a quiddity indistinctly as a unity before we know it distinctly by understanding its parts.
- Yes, in the sense that we know simple quiddities of things before we engage in complex composition or division.
- No, in the sense that abstractions like “point” or “unity” are known only by privation. A point is “something which has no parts.” We know things with parts before we can consider something without parts. This is because these concepts are opposed to natural, corporeal reality.
by David Fleischacker
Further, love is the act of a subject (principium quod), and as such it is the principle of union between different subjects. Such union is of two kinds, according as it emerges in love as process to an end or in love in the consummation of the end attained. The former may be illustrated by the love of friends pursuing in common a common goal. The latter has its simplest illustration in the ultimate end of the beatific vision, which at once is the term of process, of amor concupiscentiae , and the fulfilment of union with God, of amor amicitiae (“Finality, Love, Marriage,” 24)
Though there is more to say on finality, I am now turning attention to the meaning of love within the 1943 essay “Finality, Love, and Marriage.” On an initial review, and I think final as well, Lonergan was only beginning to move into a deeper explanatory account of love in 1943. His use of terms derived from faculty psychology and his notion of appetite illustrate this beginning. We must remember however that the use of faculty psychology does not make something false. What happens once one shifts into intentionality analysis is a transposition which sometimes results in a translation of a term into the intentional framework and, at others, an elimination of a term. For example, I would argue that the potential intellect gets translated into the capacity for self-transcendence, and hence expanded and united within the light of all the transcendental notions. Likewise, the agent intellect becomes translated into the transcendental notions, and thus more adequately expanded as well. Thus, Lonergan’s formulation of love in 1943, even if in faculty psychology, can be transposed, something which Lonergan had done by the time he wrote Method in Theology.
First, let’s look carefully at the 1943 text. This section is titled “The Concept of Love.” Notice Lonergan is using the term concept. However, in his opening line, he identifies love as utterly concrete.
The difficulty of conceiving love adequately arises from its essential concreteness and from the complexity of the concrete.(23)
Love is neither a concept or an abstraction, but of course in talking about it, one does have to conceive it.
In conceiving of love, Lonergan develops four aspects, the first two dealing with the nature and act of love itself, and the second dealing with the subject who loves. The first two clearly are formulated within faculty psychology. Love is an act of a faculty. A faculty is a kind of power that is constitutive of what a living thing is. It gives the living thing the ability to carry out certain type of operations. To get an insight into a faculty, one has to carefully analyze a whole landscape of operations and then in examining the operations, discover fundamental characteristics that unite those operations. So, seeing, hearing, tasting, touching, and smelling all have a material element to them, such that the very operation itself regards a spatial-temporal element. As well, these sensate operations allow one to be present and conscious of sense objects. And hence recognizing that all of these sense activities both have a conscious element and a material element would allow one to then formulate a common power or capacity that one has in these types of activities. This becomes the source of the insight into a particular faculty or power. Other operations transcend certain material limitations, and the principle examples of this are the activities of understanding and knowledge. One can posit a common power or faculty to these spiritual (non-material activities), such as the faculty if the intellect. Now on to each of the four aspects.
First Aspect: Love as an actuation of a faculty
Lonergan formulates love as a realization or actuation of faculty. Specifically, it is a faculty of appetite, and love is the central appetite – “it is the pure response of appetite to the good” (23) Other responses are derivative – desire, hope, joy, hatred, aversion, fear, and sadness. Hope is the expectation to become present to that which is love. Hatred is toward that which has harmed the good that is loved. Fear arises in response to the possible loss of the good that is loved. Sadness is the response to that good as lost. Joy is the enjoyment of the good as present. Love is key. It is central. There is nothing false in formulating love in this manner. Identifying it with a faculty, and a fundamental appetite is to recognize that it is a real power or capacity of the human person.
Second Aspect: Love of a beloved as first principle
The second aspect is that it is the principle – “the first in an ordered series” – that initiates a process to its end, which is that which is loved. One can think of simple vital desires for example. The desire for food is not only the “form” of the end process by which one goes out to find, hunt, or grow food, but it is the first principle of that entire process, and it has as its object the end, the food itself. In the case of love it is the beloved. The beloved becomes the first principle that moves the person in love to the beloved.
Third Aspect: Unification of subjects toward an end
The third aspect highlights that the act of love, the act of this fundamental appetite, this first principle of movement to the beloved as term, bonds the subjects who are in love based upon their common pursuit of an end. Those who have not yet reached the end, and rather are still in pursuit of it, become bound when pursing that end collaboratively. Lonergan draws this out further through Aristotle’s notion of friendship in a later section of his essay. Notice that here, Lonergan does not specify the end that is pursued, because any good ends pursued can unite individuals to each other. This pursuit also perfects the human subjects as such, and thus bonds them to each other for each other, but that is the point of the next aspect.
Fourth Aspect: Love of Beloved as United, as Consummated
The fourth aspect highlights that love as realized unites subjects as mutual persons who enjoy the good that each is, a mutual unity that is based upon the good that each person is and has become. The ultimate example of this aspect that Lonergan identifies is the beatific vision, “which at once is the term of process… and the fulfillment of union with God” (24).
It is important to note that Lonergan says these are simultaneous aspects (23). The differences between each is a different focus upon what is “utterly concrete.” By simultaneous he means that one does not happen without the other, even if the individuals involved may be focusing in upon one of the aspects and not the others.
Contrast to love in Method in Theology
There is not only a clear difference of words between 1943 and 1972, but a clear difference in scope. Lonergan by 1972, was able to formulate love in terms of insights that he had into the structure of consciousness, specifically in terms of the capacity for self-transcendence, and the different states of being of that capacity. One not only has the notion of potency in a capacity, but it is a potency that has a directly relationship to states (which is derived from statistical notions – the difference between actual frequencies from ideal frequencies gives one an understanding of the state of something), and it includes a clear differentiation of the notions that constitute the capacity as a whole – the transcendental notions. Lonergan thus could formulate love not as merely an actualization of a faculty, but one might say the actualization of the faculty of all faculties, the base of all bases. Love is basic because it orientes all levels of consciousness. All the questions that one pursues are guided by that which one loves. In other words, the state of being orients all the operators of human development at all levels of conscious intentionality. Love is the actuation of the capacity for self-transcendence, and the more profound it is, the more it underpins, penetrates, and transforms all of one’s horizon.
This does not negate the insights Lonergan had in 1943, but it does formulate these insights more clearly, and it expands upon what he understood of love. It is still utterly concrete, and so concrete that nothing that human beings do escape it, because even getting up in the morning means there is some basic actuation of the capacity, some basic state of one’s being. It is an actuation of a kind of faculty, but not just among others. Rather, it regards the capacity for any human intentional operator and operation. It is a central appetite, but it is also a the central finality of all human activities. The transposition of faculty psychology into intentionality analysis reinforces what Lonergan says about love in 1943 and expands it. Furthermore, the last two aspects can be understood more deeply. When one understands that love is a realization of the capacity for self-transcendence, and that all other operators and operations thus emanate from this realization, then one comes to understand the more comprehensive scope upon which subjects can be bound to each other both as they self-transcend, and as they reach the fulfillment of their self-transcendence. This is especially true when one transposes the beatific vision into a perfection of the human capacity for self-transcendence by the gift that is the Transcendent, the ultimate meaning and ultimate value because the Transcendent is the only true realization of the capacity. Lonergan’s reflections upon Christology and Trinitarian theology draw this out even more (and one might add his work on grace).
Just a few things to think about as we start this exploration on Lonergan’s notion of love in “Finality, Love, and Marriage.”
Square root of two as an irrational number
by Br. Dunstan Robidoux OSB
edited by Mr. Michael Hernandez MA
When Lonergan discusses inverse insight in the first chapter of his Insight: A Study of Human Understanding, he presents a mathematical example to illustrate the nature of inverse insight as an act of understanding which realizes that an expected, desired intelligibility is not to be reasonably nor rationally expected. (1) In some situations, in some inquiries, to anticipate in the type of intelligibility sought is to perdure in “barking up the wrong tree” and to waste time by asking irrelevant questions. However, since Lonergan’s example pains readers who have never acquired any easy familiarity with mathematics and who have lost what familiarity they once had, this paper will parse out the discussion in ways which should help. Let us begin.
Lonergan’s argument consists of the following sequence of numbered propositions:
Proposition 1: The square root of 2 is some magnitude greater than unity and less than two
Proposition 2: One would expect it to be some improper fraction, say m/n, where m/n are positive integers and by the removal of all common factors m may always be made prime to n.
Proposition 3: If this expectation correct, then the diagonal and the side of a square would be respectively m times and n times some common unit of length.
Proposition 4: So far from being correct, the expectation leads to a contradiction.
Proposition 5: If sqrt(2) = m/n, then 2 = m2/n2
Proposition 6: But, if m is prime to n, then m2 is prime to n2
Proposition 7: In that case, m2/n2 cannot be equal to two or, indeed, to any greater integer
Proposition 8: The argument is easily generalized, and so it appears that a surd is a surd because it is not the rational fraction that intelligence anticipates it to be
To understand the controversy about the square root of 2, let us look briefly at the historical origins of the problem.
First, with respect to numbers, the square root of 2 is some sort of number. Numbers fall into different types or species since the square root of a number is unlike the number whose square root is sought. Numbers rank as human inventions since they do not exist as purely natural entities apprehended by sense. They were invented as the human need for them arose. (2) Different needs, as they emerged, formed new types of numbers. Hence, the first type of numbers invented were the counting numbers, sometimes cited as natural numbers: 1, 2, 3, 4, 5…. (3) They arose as correlatives to designate quantities: how many of this or how many of that. For example, “3” identifies three sheep or three fish. The sequence of counting numbers is potentially infinite since the human mind can keep adding units of 1 to form an ever greater number. Subsets are similarly infinite in their sequences. The odd numbers, as in 1, 3, 5, 7…, are infinite as are the even numbers, 2, 4, 6, 8…. On a straight line, in one vector, each natural number can be represented by one point on a line ad infinitum. (4)
A second species of number emerges in whole numbers when counting proceeds in reverse: toward and beyond 1. Nought or zero emerges as a number to signify the absence of some item. The creation of this numerical designation signifies an “empty set” as in “the number of Eskimos living in our house is 0.” (5) The inclusion of 0 with the counting numbers thus creates a larger system of numbers than the old quantitative counting numbers. Enumeration now begins from 0 which can also be represented by a point on a line.
A third, more comprehensive set of numbers emerges when the reverse counting which had led to 0 continues backwards to include numbers that are now less than zero. The result is a potentially infinite set of negative whole numbers. When these numbers are then added to the numbers that have already been generated by counting from zero upwards (the positive whole numbers), the result is a set of numbers known as integers. An integer is defined as a positive or negative whole number as in 0, ±1, ±2, ±3, ±4 . . . (6) The negative and positive signs indicate direction: all these numbers are directed. On a number line, the negative numbers go to the left of 0 while the positive go to the right. Each number has a point.
Rational numbers deriving from a ratio or fraction of integers or whole numbers emerged when it became necessary to specify measurements which are parts of a number. How does one express a length which is between 4 and 3 meters or 4 and 3 cubits? Is a loaf of bread, equally divided among 5 persons, divided in a way where each piece has a numeric value of 1/5? Does the addition of 1 piece to another not result in a union with a numeric value of 2/5? A number designating parts thus consists of parts in its makeup. There are two halves: a numerator above a line and denominator beneath. (7) The denominator indicates how many intervals exist between two possible whole numbers while the numerator indicates how many of these intervals are pertinent in a given measurement. The denominator cannot be 0 since, otherwise, one would be indicating that no intervals or parts exist between two numbers. Why specify numerators for portions or parts that do not exist? A rational number is commensurate with given lengths that are being measured. A number which includes a fraction can be assigned a point on a line. The position is determinate.
In the 5th Century B.C., the Pythagoreans initially assumed that numbers measuring the sides of a triangle are rational where each number can be expressed as the ratio or quotient of two integers (or two whole numbers). (8) Divisors (or denominators) exactly divide into numerators as in ½, 1/10, and 1/100: a half (or .5), a tenth (or .10), and a hundredth (or .100). A ratio as the quotient of two numbers or quantities indicates relative sizes. (9) The ratio of one number to another is expressed in terms of a/b or a:b. It was assumed that a one-to-one correspondence joins straight-line segments of length with rational (whole) numbers. (10) In attempting to measure the diagonal of a square by taking a small part of one side as the measuring unit, one should be able to fit the measuring unit a fixed number of times within both the side and the diagonal. (11) All lengths are measurable and commensurate in terms of rational (whole) numbers. Two quantities are commensurable if their designating numbers are multiples: both numbers arise as products of common factors (a factor being a number that divides a given number exactly or completely (12)). For instance, 16 and 12 are commensurable since both exist essentially as multiples of 1, 2, or 4: each exactly divides into 16 and 12 and no other number exactly divides 16 and 12. By multiplying one or more of these numbers together, one arrives at numbers 16 and 12 (in conjunction with other possible numbers that are also commensurable). Similarly, 3 feet and 2 inches designate commensurable quantities since 3 feet contains 2 inches an exact or integral number of times. (13) Hence, according to Pythagorean assumptions and expectations, the length of a square’s diagonal whose side is represented by a rational number should be represented by another rational number.
On the basis of this belief in rational numbers and the corresponding commensurability of lengths, according to the Pythagoreans, “numbers are things” and “things are numbers.” All things are numerable in terms of whole numbers and their properties. (14) A cosmic harmony exists in the universe given the interrelation of things based on whole numbers where the relation between two related things can be expressed according to a numerical proportion or ratio. For example, in music, ratios of concord exist between musical sounds (pitch) and whole numbers since by halving the length of a string on a lyre, one can produce one note one octave higher. All harmonies can be represented by ratios of whole numbers and, by extending this principle to all things, through geometry one can explore the configurations of perfect solids in the belief that all lengths are measurable in terms of rational whole numbers.
A crisis emerged for the Pythagoreans when, possibly prior to 410 B.C., they realized that some numbers, though real (as existing), class as irrational because they cannot be written as whole numbers, as integers or as quotients of two integers. (15) No assignable point of a line can be given them. Some numbers do not exist thus as whole numbers as can be seen through a deduction from Pythagoras’ Theorem in geometry which describes the relation between the lengths of the sides of a right-angled triangle in the following terms:
In a right-angled triangle, the square on the hypotenuse [the side of right-angled triangle opposite the right angle] is equal to the sum of the squares on the other two sides. (16)
Thus, if the hypotenuse has a length c and the other two sides, lengths a and b, then c2 = a2 + b2. Now, if, in a square, the side length constitutes 1 unit, then
c2 = 1 + 1
c2 = 2
c = sqrt(2)
The diagonal is 2 units in length. (17) This number obviously designates some magnitude greater than 1 or unity but less than two where, initially, one naturally assumes that this number is an improper fraction expressing a whole number (an improper fraction being defined as a fraction whose numerator exceeds its denominator as in 4/3 versus 3/4, designating a proper fraction (18)). (19) However, if the square root of 2 cannot be expressed as a whole number, its irrationality in terms of whole number properties creates major problems given expectations which assume the adequacy of whole numbers. After all, conversely, if only rational numbers exist, the hypotenuse of every right-angled triangle will have a length that cannot be measured by any whole number. (20) It is incommensurable, non-measurable: in the relation between the diagonal d and an adjoining side s, d cannot be divided by any unit common to s an integral number of times. In trying to effect any measurements, the Greeks found that however small or large would be their measuring unit, it failed to fit within both the diagonal and the adjoining side a fixed number of times. (21) A measuring unit that would fit the adjoining side a fixed number of times would not fit the length of the diagonal. It was either too short or too long. Proofs demonstrating the irrationality of 2 came in a number of varieties.
Aristotle refers to a proof on the incommensurableness of a square’s diagonal with respect to a side that is based on the distinction between odd and even, an odd number being an integer that is not divisible by 2 while an even number is divisible by 2. (22) To understand how this argument works, a digression on prime numbers introduces the discussion.
A prime number is a whole number with exactly two whole-number divisors, itself and 1. Some primes are
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, . . . , 101, . . . , 1093
Prime numbers are the building blocks of other whole numbers. For example,
18 = 233 40 = 2225 105 = 357
This type of factorization is possible for all nonprime whole numbers greater than 1 and it illustrates the fundamental theorem in arithmetic known as the Unique Factorization Theorem (23) which says, as follows, about the prime decomposition of a whole number:
Any nonprime whole number (greater than one) can be written as the product of a unique set of prime numbers. (24)
Every prime integer shares the important property that if it divides a product of two integers, then it must divide at least one of the factors (prime numbers being only divisible either by themselves or by 1). This theorem is important in many parts of mathematics. In one simple consequence, when the square of any whole number is written as a product of primes, each prime occurs as a factor an even number of times. For example:
(18)2 = 1818 = 233233 = 223333
two 2’s four 3’s
(40)2 = 4040 = 22252225 = 22222255
six 2’s two 5’s
(105)2 = 105105 = 357357 = 335577
two 3’s two 5’s two 7’s
To prove that the square root of 2 is irrational, let us suppose that 2 is a rational number; that is, suppose that 2 = m/n, where m and n are whole numbers (necessarily greater than 1). Then:
2 = m2/n2
2n2 = m2
Now, imagine that both n and m are written as products of primes where, for instance (using algebraic notation), n = xy while m = zpt. But, as previously noticed, both n2 and m2 must then have either an even number of 2’s or no 2’s. But, in the above equation, the prime 2 appears on the left an odd number of times either once (if n2 has no 2’s) or more than once (if n2 has an even number of 2’s) but, on the right, the prime 2 appears either an even number of times or no times. This is clearly impossible since, given the nature of primes, m2 equates with a number or produces a number that has either an even number of 2’s or no 2’s. A contradiction obtains despite the equals sign. Therefore, what can be wrong? The only thing that can be wrong is our supposition that 2 is a rational number. If this proof is applied to other primes in terms of square roots for 3, 5, 7, . . ., the same dilemma results. (25) Odd clashes with even to demonstrate the irrationality of these numbers. Hence, could all numbers be the kind of numbers that the Pythagoreans had postulated? Are they all rational?
In Boyer’s version of the mathematical proof demonstrating the incommensurableness of the square root of 2 through the contrast between even and odd, he argues as follows: (26)
1. Let d and s respectively signify the diagonal and side of a square and let us assume that they are commensurable: the ratio d/s is rational and equal to p/q, where p and q are integers with no common factors.
2. given the Pythagorean theorem d2 = s2 + s2 reconfigured as d2/s2 = 2 (since d2 = 2s2), if the ratio d/s = p/q (p and q being integers with no common factor), then (d/s)2 = p2/q2 = 2 or p2 = 2q2
3. therefore, p2 must be even since its equivalent 2q2 is divisible by 2 (which corresponds to the definition of an even number as a number divisible by 2).
4. hence, if p2 is even, p is even since p2 when decomposed into constituent prime numbers necessarily includes at least two instances of 2 as both a prime number and a factor, and the presence of 2 in p makes p an even number since it is divisible by 2 (which again corresponds to the definition of an even number).
5. as a result, q must be odd (not divisible by 2) since, according to conditions stated in aforementioned proposition 2, q is an integer with no factors common to p and so it cannot have 2 as a constituent prime factor.
However, letting p = 2r and substituting in the equation p2 = 2q2 with, hence, the result that 4r2 = 2q2, 4r2 = 2q2 as reconfigured becomes q2 = 2r2. Then q2 must be even; hence q must be even (according to the argumentation which had explained why formerly p2 and p must both be even). However, a contradiction follows if one argues that q is both odd and even. No integer can be both odd and even. As a consequence, it thus follows that the numerical relation between d and s is incommensurable. (27) The result is not a definitive whole number.
A third but second species of proof relying on a study and understanding of prime numbers demonstrates the absence of an anticipated whole number by adverting to the relation between d and s. If, indeed, d (a whole number) is decomposed into constituent prime numbers and s (a second whole number) is similarly decomposed, and if no factor is common between them, the improper fraction d/s can never be resolved into a whole number since, in every case, the denominator does not perfectly divide into the numerator to produce an anticipated, desired whole number. The result is always some sort of fraction which, by definition, is not an integer, a whole number.
A geometrical proof that evidences the existence of irrational numbers in general, and not 2 specifically, designates a third species of proof. (28) Its lesser abstractness suggests earlier origins predating the construction of later proofs using other types of arguments. When examining the sides and diagonals of a regular pentagon (defined as a five-sided polygon with all the sides possessing equal length) and the respective relations between s and d, if the diagonals of this pentagon are all drawn, they form a smaller regular pentagon whose diagonals can also be drawn to form a smaller regular pentagon ad infinitum. Hence, pictorially, the relation or ratio of a diagonal to a side in a regular pentagon is indeterminate because it is indefinite. It is irrational. Similarly, if a straight line is divided into two parts and one part is divided into two smaller parts, it will be possible to keep dividing lengths indefinitely. (29) No determinate end is reached. Our expectations meet with frustration as our inquiry encounters mysteries that occasion questions about the adequacy of our intelligible anticipations. What is to-be-known cannot be known too easily or simply.

Higher Viewpoints: Part One
From Arithmetic to Algebra: the transition
by David Fleischacker
Draft Version 1
Copyright © 1997. All rights reserved
(This is a reflective commentary on one facet of sections 1 – 3 of chapter one in Insight.)
I. The Viewpoint of Arithmetic:
In Insight, Lonergan builds to the notion of a higher viewpoint after he has developed an understanding of clues, insight, concepts, questions, images, and definitions. A viewpoint is not merely a definition, but a set of systematically related definitions (and of the operations that underpin both the definitions and their systematic relations). It is not a single definition. Defining a circle, for example, is not a viewpoint, but it does arise out of a geometrical viewpoint, and contributes to it. The same is true of the distributive or commutative properties of algebra, or the power rule of calculus. They do not constitute an entire viewpoint, but they are components.
Lonergan illustrates lower and higher viewpoints with arithmetic and algebra. A mathematical viewpoint is constituted by rules, operations, and symbols (or numbers). The rules implicitly define the operations, and the operations implicitly define the symbols. What does he mean by this?
A. The Deductive Expansion of Arithmetic (the first horizontal development in mathematics):
Lonergan begins with arithmetic, more specifically with addition. One may count sheep or goats or troops in an army or persons inhabiting a town. The counting involves the operation of addition– one plus one plus one, and so forth. It is an activity relating quantities and defining them in terms of each other. The basic unit of this quantity can be symbolized, let us say with a “1” or “I”. Other symbols can be used to represent what one is doing when adding, such as “+” or “plus.”
Any number of symbols can be invented to represent operations (addition, subtraction, etc..) and numbers (some of which, Lonergan notes, are better conducive to the future development of mathematics than others because of their potential for leading to further insights). In order to simplify the ongoing definitions of numbers most cultures that developed mathematics introduced repeating schemes. Some introduced repetitions based on 30 or 60 (think of our clocks and watches). Our present system is based on repetitions of 10, so we developed a symbol for zero through nine, and then, once ten is reached, we add a place to the left indicating the number of “tens.” Then once the tens reaches beyond the ninth position, we add the hundreds, then thousands, and so on (Computers, you may have heard, are based on a binary, with ones and zeros).
From adding numbers we can develop, as Lonergan notes, a definition of the positive integers.
1 + 1 = 2
2 + 1 = 3
3 + 1 = 4
etc., etc., etc..
Once the insight is gained, or in other words, when one understands what is meant by “etc., etc., etc.” then one can continue to indefinitely define any positive number. From this, one can create an entire deductive expansion of a viewpoint or horizon in arithmetic, and continue indefinitely to define the whole range of positive integers. One can also construct mathematical tables using 2s, 3s, 4s, etc..
2 + 2 = 4
4 + 2 = 6
6 + 2 = 8
Etc., etc., etc.. (“2” is added in a repeating fashion)
3 + 3 = 6
6 + 3 = 9
9 + 3 = 12
Etc., etc., etc.. (“3” is added in a repeating fashion)
4 + 4 = 8
8 + 4 = 12
12 + 4 = 16
Etc., etc., etc.. (“4” is added in a repeating fashion)
ETC., ETC., ETC. (For the entire process above)
Notice how all of the numbers are defined in terms of the operation of addition. It is the basic insight that grounds this operation which allows for the construction of an entire deductive expansion which creates a “world” or viewpoint, even if rather limited. It is a first, horizontal development of a horizon in mathematics.
B. The Homogeneous Expansion (the second horizontal development in mathematics)
One can become more creative, and begin to add a number to itself say three or four or five times.
1 + 1 + 1 = 3
1 + 1 + 1 + 1 = 4
2 + 2 + 2 = 6
3 + 3 + 3 + 3 = 12
Etc., etc., etc..
And, instead of writing this with three 1’s or four 1’s or three 2’s or four 3’s, shorthand notation can be developed.
1 x 3 = 3
1 x 4 = 4
2 x 3 = 6
3 x 4 = 12
So, one introduces a different symbol, namely an “x” to indicate the number of times one is added to itself. Notice how this new symbol is still defined in terms of the old operation of addition. It means “adding” a number to itself so many times.
Creativity does not have to stop. If we can add one to another, then what happens if we take something away. We had three sheep, sold one, and now are left with two. This is the opposite of addition, and we can give it the symbolization of “-“(1) and call it subtraction. Again, one can develop charts of subtraction, just as with addition and multiplication. Likewise, just as one can reverse addition by removing something, so one can reverse multiplication by removing a number so many number of times. So, just as one can add 2 to itself four times to get 8, so one can remove 2 from 8 four times. This of course, is division.
Creatively constructing a viewpoint by introducing new symbols such as subtraction, multiplication and division, is what Lonergan calls a homogenous expansion. One has introduced new symbols relating numbers, but notice how everything is still thought of in terms of addition. Subtraction is the reverse of addition. Multiplication is the addition of a number to itself so many number of times. Division is the reverse of that. And if one wishes to add powers and roots, they likewise can be defined in terms of addition. A power is the multiplication of number by itself so many number of times. Thus to define this in terms of addition, let the number that is powered equal y, and the power equal z. Thus, the answer is defined as the number, y, which has been added to itself y number of times, thus forming a group, a group which in turn is added to itself again y number of times, and repeating this formation of groups z-1 number of times. This can be illustrated with 3 to the power of 4. 3 to the power of 4 is the same as 3 x 3 x 3 x 3. The first group arises by converting 3 x 3 into 3 + 3 + 3. This group is then added to itself 3 times in order to get the equivalent of 3 x 3 x 3. This results in a second group that can be written as [(3 + 3 + 3) + (3 + 3 + 3) + (3 + 3 + 3)]. Finally, take this second group and add it three times to itself. The final answer comprises this third group, which can be written as
[(3+3+3) + (3+3+3) + (3+3+3)] + [(3+3+3) + (3+3+3) + (3+3+3)] + [(3+3+3) + (3+3+3) + (3+3+3)] = 81
A “root” is the reverse of this procedure. So, the 4th root of 81 requires breaking down the 81 into three groups, where the basic group, which when discussing powers was called the first group, is comprised of a number that has been added to itself its own number of times. This number is the answer. So, even powers and roots can be thought of in terms of addition.
II. Algebra: The Higher Viewpoint ( a vertical expansion in mathematics)
The homogeneous expansion of arithmetic has not introduced any new rules. One can define each of the new operations in terms of addition (or the reverse of addition). New rules are only introduced when one starts “observing” patterns in arithmetic, and doing this initiates algebra (Lonergan notes that the image which leads to algebra is the doing of arithmetic). What does this mean? Lonergan notes that this “turn of question” that lead to the discovery of patterns in arithmetic occurred because of questions such as;
What happens when one subtracts more than one had?
Or what happens when division leads to fractions?
Or roots to surds?
Each of these refers to various problems that emerge in the homogenous expansion. Their answer lies in grasping patterns. Questions emerge which ask, what, in general, happens when one subtracts numbers, or adds numbers, or divides numbers, or adds powered numbers, etc.? Today, these initial patterns are given such names as commutative, distributive, and associative properties. Let us illustrate these laws.
A simple pattern is adding a number to zero.
1 + 0 = 1
2 + 0 = 2
3 + 0 = 3
4 + 0 = 4
5 + 0 = 5
6 + 0 = 6
etc., etc., etc..
The etc., etc., etc., again is introduced to gain the insight. A number added to zero results in an answer that is that number. This can be symbolized by creating a symbol that represents a number (or in other words, a variable). Let that symbol be “A.” Below is the formulation of this pattern,
A + 0 = A
Another example is the multiplication of a number by 1.
1 x 1 = 1
2 x 1 = 2
3 x 1 = 3
4 x 1 = 4
5 x 1 = 5
etc., etc., etc..
If one recognizes the pattern, then one notices that a number multiplied by one, gives the number. Hence, this insight can be symbolized.
A x 1 = A
The same is true with the various laws or properties (as they are actually called) mentioned earlier. The commutative property of addition states that A + B = B + A. The commutative property of multiplication states that A x B = B x A. The associative property states that (A + B) + C = A + (B + C). The parenthesis means add these numbers first. The associative property of multiplication states that (A x B) x C = A x (B x C). As an exercise right now, try expressing these patterns using actual numbers and the “etc., etc., etc.” as I did above.
You can practice this further by opening any algebraic text, and examining the numerous rules about addition, multiplication, division, powers, roots, addition of powers, multiplication of powers, multiplication of roots, and the inverses of each of these formulas (subtraction of powers and roots, division of powers and roots, etc..)
Notice how one is understanding the operations in a manner beyond that of addition. One begins to grasp, for example, that multiplying two negatives leads to a positive, that dividing a negative into a negative also leads to a positive and many other characteristics. These recognized patterns then begin to form new rules, which constitute the higher viewpoint called algebra. These rules guide one in solving problems, since they implicitly define how one is to carry out operations and define the new symbols of A’s, B’s, and C’s, which represent variable numbers (this will be discussed with more precision and examples in a later commentary). The rules constitute a vertical expansion of the mathematical horizon.
Like arithmetic, algebra also has a deductive and homogeneous expansion, or, at least something analogous. This is for a later section.

by David Fleischacker
“For the final cause is the cuius gratia, and its specific or formal constituent is the good as cause.” (Finality, Love, Marriage, 19)
This quote” falls within the section on vertical finality in “Finality, Love, and Marriage.” In the paragraph before this quote, Lonergan was introducing the difficulties in apprehending finality. It is something that can be easily overlooked by the positivist because “quite coherently, any positivist will deny final causality.” Instead, the positivist will only admit efficient causality. Lonergan in short, defines finality in terms of final causality. One wonders if he had yet broken from Aristotelian science sufficiently to provide an adequate account, even heuristically, of marriage and the marital acts. I suspect many would say no.
To restate this difficulty, if vertical finality is defined in terms of final cause, it would seem that Lonergan has not adequately defined finality yet. There is some truth in this as I stated in the last blog — since it seems that in light of Lonergan’s formulation of horizontal finality, he had not yet reached his more general formulation of finality that one finds in Insight, where it is isomorphic with the notion of being, and not related to essence alone (though it is related since essence or form is a component of being). Just as one can expand on the notion of horizontal finality, so one can do the same with vertical. Let us push this a bit in this blog to see where it goes.
As the quote up top indicates, Lonergan is defining final cause in terms of the good. In this section on vertical finality where he criticizes the positivist, Lonergan notes that the positivist can acknowledge motives and terms, but only as efficient causes. The blindspot of the positivist is the denial of these motives as good and these terms as good. In short, Lonergan is saying that in the potency, there is an orientation to the good that he calls finality.
One can find this orientation to the good throughout Lonergan’s later writings. In fact, it becomes more prominent, not less, as he formulates in a clear fashion the fourth level of consciousness and delineates the capacity for self-transcendence not in terms of one notion (being) as he does in Insight, but in terms of three transcendental notions — intelligibility, being, and the good (Method in Theology, 34 – 35 or 104- 105). As well, one can think of his formulation of the human good in chapter 2 of Method in Theology, especially the notion of the “terminal good” (Method in Theology, 51). In both cases, whether one thinks of the transcendental notion of the good/value or in terms of terminal value, these operate in the same manner as Lonergan’s formulation of a final cause in 1943. In other words, the transcendental notion of value operates like the notion of being, and hence it is isomorphic with the good. And terminal value is the good as a term that is truly good.
Though their is a similar heuristic element to final cause in 1943 and Lonergan’s formulation of the notion of value later, there is an expansion. Just as an expansion occurs in relating finality (whether horizontal or vertical) to the notion of being in Insight, so now one can isomorphically relate finality to the entire capacity for self-transcendence, which is constituted by the three transcendental notions–intelligibility, being, and the good. To do this is not to say that what Lonergan defined as finality in 1943 is wrong, but rather it is to open up its meaning to the entire nature of the universe of intelligible and existing goodness.
Think about how Lonergan’s development of the capacity for self-transcendence actually points out a limitation in Insight. Lonergan would have formulated the good in Insight in a manner similar to Aquinas, as convertible with being. This point would be true later as well, but it receives some nuances. The good as a distinct transcendental notion in later writings, hence distinct in the human subject’s apprehension of the good, especially the hierarchy of the good/value, indicates the differential of something as existing (or some occurrence of a conjugate form as occurring) versus something as good. In 1943, Lonergan introduced this goodness to being in terms of a final cause. In other words, being and the good are more explanatorily developed in later writings but still operative in earlier writings. Final cause is not eliminated so much as explanatorily developed. The manner that he used it in 1943 is still valid within its frame work.
Why was it and is it still valid? This validity is similar to how the Newtonian formulation of gravitation is valid within general relativity, but it is a more limited account. One can transpose the 1943 Lonergan into 1983 by formulating finality as the metaphysical and meta-ethical isomorphism with the capacity for self-transcendence. This would further open the heuristic exploration of marriage and love that he formulated in 1943, and place his insights within a larger framework. Already in the last blog, I have started to do this by uniting horizontal and vertical finality in terms of potency as one finds in Insight. One can do more by relating finality to emergent probability as the emergent good. The upwardly directed dynamism of finality for intelligibility, being, and the good/value (I have been using good partially because I do get tired of the relativistic overtones of the term “value” in modern culture). Such a finality would apprehend the universe in its proportionate existence as an emerging good. This recognizes the universe as an ultimate friendly universe in its very nature. This also means that the entire intelligibility and being of marriage is not only real but good — and so getting that meaning right is crucial if the historical and traditional breakthrough into marriage is not to fade into the shadowland of scotosis or individual bias or group bias or the general bias (on the notion of scotosis and bias, see Insight, chapters 6 and 7).
By David Fleischacker
Four ideas about the generic relationship of horizontal and vertical finality stand out in Lonergan’s 1943 essay – “Finality, Love, and Marriage.” It is important to note that I have not passed much beyond exploring the first section of the 1943 essay, which makes general statements about finality. In his later sections, he treats of love and the personalist elements of marriage within the framework of finality, and so these later elements will be crucial to comprehend what he contributed with this essay. That will be for future blogs.
First Idea: Horizontal as Essential, Vertical as Excellent
The first deals with linking horizontal to what is essential, and then vertical to what is excellent. This is mentioned a number of times (see for instance pages 18, 22-23, and 48). Essence refers to what something is (Lonergan uses nearly the same formulations of horizontal, vertical, and absolute finality in his 1976 essay, Mission and Spirit, but instead of essence he just writes that the proportionate end “results from what a thing is” — A Third Collection, page 24). Essence constitutes a kind of limit to the types of activities or operations that a thing can engage upon or into which it can develop. The excellent refers to a higher level perfection that can emerge from the lower. Lonergan’s use of essential and excellent is directly linked to the course he was teaching on marriage at the time, and to Casti Cannubii, in which the essential and excellent ends of marriage were distinguished. I find it interesting that he defines horizontal in terms of essence, but he does not define vertical in terms of excellence. Rather, he defines vertical finality in terms of a dynamic emergence of properties that arise from a conjoined plurality.
This distinction between horizontal and vertical finality seems to be lost by the time of Insight where the terms are not used at all. I would argue that this is a result of a broader, more general formulation of finality in which it is understood as proportionate or isomorphic with the notion of being (and hence the desire to know). Finality is the “upwardly but indeterminately directed dynamism towards ever fuller realization of being” (Insight, chapter 15, section 6). As such, it is simply the potency of the universe for the emergence and maintenance of each and all intelligible being. However, Lonergan does use the term “vertical” in a similar fashion to its use in 1943, though only once, when discussing the relations of a lower manifold to a higher order (Insight, chapter 15, section 7.3). Hence he is not speaking of finality but of developmental relations. And instead of horizontal, he speaks of lateral developments. In Insight, the only kind of distinction he makes regarding finality is in terms of minor and major flexibility (hence not horizontal and vertical), but explanatorily these are not different, especially in terms of the meaning of finality as a potency that is a directed dynamism (Insight, chapter 15, section 5). In Insight, finality as such is not merely within an individual, or species, or genus, but it is the potency for fuller being in each and all individuals, species, and genii.
There is one key notion that links the 1943 essay and Insight. It is the notion of a concrete plurality which becomes formulated into terms of both the non-systematic and statistic residues in Insight. The potency of a plurality of acts ends up being central to understanding the open ended dynamism of each individual, species, and genus. Take for instance a carbon atom. The carbon atom itself is a chemical conjugate, and if in act, it is an existing chemical atom. Within an existing atom of carbon, the concrete plurality that is a potency for other chemical forms is the sub-atomic elements which are either quarks or compounds of quarks. These quarks and compounds of quarks are the lower manifold pluralities that have the potentiality for being informed as other chemical elements or compounds. In carbon, there are sufficient materials to form other elements or compounds through atomic or nuclear changes–as long as the total masses of these elements and compounds does not exceed that of carbon. One could theoretically form hydrogen or helium, or any other elements up to carbon from a carbon atom. Hence this concrete plurality of sub-atomic elements is the location of the potency for dynamic change.
In 1943, Lonergan tended to limit this dynamic notion of finality to vertical finality, since such finality is based in the “fertility of a concrete plurality” (and this is equal to an indeterminate but directed dynamism to his use of vertical finality). However, one finds this concrete plurality to some degree in his use of horizontal as well. There are a few points in his 1943 essay where Lonergan identifies a statistical relationship between two events on the same horizontal level (namely the conjugal act and conception—see page 46, footnote 73), but he tends to identify horizontal as rooted in essence still, rather than the potency of a non-systematically related set of aggregates that can become “conjoined” into an order whether on the same plane of being or a higher plane.
As mentioned, later in his life, Lonergan does reintroduce vertical and horizontal finality in his third collection that reprints a 1976 paper titled “Mission and Spirit.” He more or less repeats the same definitions as given in 1943 but without the link of horizontal to essence/natural law and vertical to concrete plurality and statistical law. Hence has a similar meaning as in 1943, but he has the developments of Insight in the background, along with the question of evolution. It is almost if he had re-read the 1943 piece, and decided to bring the notions of horizontal, vertical, and absolute finality to attention. Just a few years earlier, in Method in Theology published in 1972, he introduces horizontal and vertical liberty (not finality) taken from Joseph de Finance (Method, pages 40, 122, 237-8, 269) but there is no clear indications of any connections to finality and the 1943 essay (one can make connections however).
Second Idea: Horizontal within the field of natural law and vertical within the field of statistical law
Horizontal finality results from abstract essence; it holds even when the object is in isolation; it is to a motive or term that is proportionate to essence. But vertical finality is in the concrete; in point of fact it is not from the isolated instance but from the conjoined plurality; and it is in the field not of natural but of statistical law, not of the abstract per se but of the concrete per accidens. (22)
Tied to linking horizontal to “abstract essence” is the idea that it is in the field of natural law (I am presuming this is what he is implying above, but I could be wrong) rather than in the field of statistical law. The notion of natural law as well as the location of horizontal finality are modified by the time of Insight. “Nature” in Insight is formulated in terms of a heuristic notion that is like naming an unknown “X” that needs to be understood (Insight, chapter 2, section 2.2). In this context, nature, and one could argue natural laws, and statistical fields are not distinct, but rather closely linked. Nature as transposed into correlations identify the conjugate forms, and statistics deals with ideal frequencies of the actuation of those forms. Hence, in Insight, Lonergan differentiates nature (and natural laws) into correlations (or functional relationships) and their statistical ideal realizations. I would argue as well that developmental operators also belong to the realm of “nature” for Lonergan. Hence, in Insight, Lonergan will shift finality not only to potency, but to a potency that is an indeterminate but directed dynamism to fuller being. Lonergan was moving in this direction with vertical finality in 1943, but had not worked it out in terms of horizontal yet.
Third Idea: Horizontal is not dynamic, the Vertical is the source of dynamism.
The claim that horizontal finality is not dynamic on the one hand and that vertical is dynamic on the other is closely related to the above two ideas. Because Lonergan was conceiving of horizontal finality in terms of essence and a type of static natural law, he had not thought through the dynamism for fuller being that actually takes place due to horizontal finality. Since in Insight, he works out his notion of finality in terms of potency and then how this notion fits in with his general theory of development (Insight, chapter 15, sections 5 – 6), even what he is getting at with horizontal finality will turn out to be dynamic as well, because there can be fuller realization of being on the same genus of conjugates. Think for example about the illustration of arithmetic development in chapter 1. Arithmetic is presented the first of three levels in math, and there are both deductive and homogeneous expansions at this level. These expansions are developmental in nature, and they arise in the potency of operating with numbers from the moment one “combines” or adds numbers. Or look at Lonergan’s formulation of minor and major flexibilities of development. Both illustrate these same points since both “rest on an initial manifold” and thus are rooted in a kind of potentiality that Lonergan would have a called a plurality in 1943 (Insight, chapter 15, section 6). Minor flexibility refers to something that can have some variation while it unfolds into its mature state, but it still reaches the same mature state. In major flexibility, a thing can unfold in a new and surprising manner which results in a shift in its mature state (Insight, chapter 15, section 6). This shift could be a different species but on the same genus, hence horizontal, or it could be to a new genus, hence vertical. An example would be if a grass became a shrub (I am presuming these are different species, and the complexity of the change from one into another may be extremely difficulty or unlikely—I do not want to enter into the explanatory challenges to this within the realm of biochemistry, genetics, and molecular biology, though I acknowledge the challenge) (If you would like to see a bit into my understanding of explanation within biology, take a look at my blog on Behe’s book Darwin’s Black Box). In this case, the relationship of the initial potency to this new species is a horizontal finality. However, the major shift could be a shift from a lower to a higher genus, in which case then a vertical development has taken place, and the relationship of the initial potency to this vertical realization is one of vertical finality. Such an example would be the shift from a vegetative form of life into something that is sensate. This is perhaps best illustrated by the development of an animal (dog, cat, etc.) from a single zygote that starts with cellular operations (or what was traditional called the vegetative level–a lower genus) and then adds sensitive operations (a higher genus).
In 1943, Lonergan tended to see horizontal finality in a static manner because of his formulation of it in terms of a kind of an essence (interestingly, he defines it similarly in his 1976 essay, so one wonders a) whether I am right in thinking that he had a more static notion of essence in 1943, or b) whether Lonergan had thought through the notion in light of Insight when he reintroduced it in 1976). However, his illustrations show that there are dynamic elements to this as well. I already mentioned the statistical link between the conjugal act and conception. Another example is the link between fecundity, the conjugal act, and the adult offspring (41). Adult offspring require development of course. And Lonergan is thinking of adult offspring in terms of the matured and differentiated organic operations, not in terms of how these are then sublated into educated adult offspring, or religiously educated adult offspring. And so, when he uses the phrase “adult offspring” alone, he identifies it as having a horizontal relationship to fecundity and the conjugal act (which is the actualization of fecundity in the union of two semi-fecundities). Yet, there is clearly a developmental relationship, similar to what he later calls a homogeneous expansion or development. Perhaps a more significant example is when he talks about the two levels above the organic, namely the life of reason and the life of grace. With the life of reason, he talks about how the potency for a life of reason in both the man and the woman at this civil level is horizontally related to the historically unfolding good life (42). This clearly recognizes a developmental unfolding which is not fully determinate, yet dynamically directed by the desire to be intelligent and reasonable.
Fourth Idea: The vertical emerges all the more strongly as the horizontal is realized the more fully
If, then, reason incorporates sex as sex is in itself, It will incorporate it as subordinate to its horizontal end , and so marriage will be an incorporation of the horizontal finality of sex much more than of sex itself; nor is this to forget vertical finality, for vertical and horizontal finalities are not alternatives, but the vertical emerges all the more strongly as the horizontal is realized the more fully. (46)
Notice here that there is a kind of dynamic element implied in the horizontal. Again, if we grasp that horizontal finality is a potency for dynamic realization of being (development), and it is distinct from mere flexible ranges of operations that are already in place, then such development is from an initial potency, and it is the dynamism in that potency that gives rise to it. And this dynamism can be more fully or less fully realized. If one turns to Lonergan’s arithmetic illustration in Insight, one can see this point right away. Arithmetic provides the “image” for algebra. The more arithmetic one does, the more one will apprehend general intelligible patterns in arithmetic. These patterns are algebraic. Adding A to B results in the same answer as adding B to A. This results in the rule that states A + B = B + A, an algebraic rule. And this is just one rule. If one has engaged in a number of operations over and over again not only with addition, but with subtraction, multiplication, division, powers, and roots, then one will begin to grasp all kinds of other patterns. One will see that multiplying A to B results in the same answer as B to A. In contrast, one will notice that one cannot do the same for subtraction or division (A-B does not equal B-A, nor does A divide by B equal B divided by A — unless A and B are the same). Algebra emerges all the more strongly as arithmetic is realized the more fully. The same is true in chemistry and biology. The more that one carries out rightly designed experiments on matter, the more fully insights arise into patterns of elements and compounds. And the more these are unfolded within living organisms, the more one understands higher order organic properties. Through DNA and biochemical processes, one grasps more fully the organic operations of the cell. And as one unpacks these cellular operations within multicellular organisms, the more one grasps the operations of those multicellular organisms (eg. respiration, immunity, digestion, etc.). These cognitive expansions horizontally and vertically have ontological parallels within all developmental entities.
It is important to note that the vertical cannot emerge and be sustained without the proper operations of the horizontal. If you eliminate the realization of the finality of stem cells which maintain and perfect cellular systems, then the systems will cease to function (respiration, immunity, etc). And if these organic events and schemes cease, then sensitive operations and schemes will cease, along with the potential for deductive and homogeneous expansions of sensitive operations. And if sensitive operations and their development fail, then there will be no insight into images, or judgment based on insights and evidence, or decisions based on judgments of fact and value, or the development of viewpoints. The lower has to flourish for every higher order to flourish that is dependent upon the lower.
In terms of finality, this means that the more vibrantly that the horizontal finality is realized, the more fully the vertical can be realized. Both the horizontal and vertical are rooted in potency, and the fact that the same potency is for both, and that the realization of higher is dependent on the lower, means that the two finalities are always necessarily dependent upon each other. The ability to see is rooted in the neural networks that are tied to sight. This potency to see is realized horizontally when the eyes are opened, the optical neurons are activated by light waves, and the associate and sensory cortices are integrating the neural activities initiated by the light waves. It is realized vertically when these lower activities arise into a conscious sensory percept. A similar relationship accrues to the development of sensory operations in relationship to the development of neural patterns, and these developments are actualizations of the finality, or potentiality, of each of these levels.
And interestingly, the higher can come to assist in the greater realization of the lower. Problems, needs, and wants that arise with regard to higher level operations require a type of expansion–sometimes a shift, and even potentially a conversion–of the lower orders such that these can then bear fruit for the higher. Lonergan in his later life sometimes called this the top down element, or the gift element, that allowed for the flourishing the lower. This does not mean that the higher is free or independent of the lower. Rather the fulfillment or realization of the higher still depends upon the lower, even if the higher is self-assembling, and acts as a mediator of the perfection of that lower. So to continue the illustration of an animal, associations of the percepts can take place through a kind of willful use of the sensory organs (cortices, etc.). An animal can “pay attention” to this or that, it can shift its body or head to see or hear or taste or touch or smell something. This higher order guidance and activation of the lower level neural manifolds allows for the further unfolding of those lower manifolds so that they can contribute to the construction of associative memories, imaginative constructs, and even feelings.
This point about the dependence of the vertical upon the horizontal–the dependence of the dynamic unfolding of the higher upon the lower–is expressed in a mulitude of ways in Lonergan’s later writings. In Insight, examine chapter 8 on things, or chapter 15 on explanatory genera and species. In Method in Theology, see his formulation of the levels of consciousness and the levels of the functional specialities. In 1943, the fecundity that is actualized through a union of two semi-fecundities has a horizontal relationship to adult offspring. The more fully this fecundity is realized at the horizontal level, the more fully it provides for a realization at the higher vertical levels and ends (good life and eternal life). One could differentiate these ends and levels in light of Lonergan’s later writings both within the parents (the four/five levels of consciousness) and the levels of the child. One could as well, place these within the unfolding of all levels of being from quarks to the actuation of the capacity for self-transcendence in a state of being in love with God.
I intend on saying more about these higher levels in later blogs. At this point, I wanted to just comment on a basic metaphysical principle regarding the relationship of the lower to a higher level of being, whether that being is conscious or not. If one eliminates the finality at a lower level, one destroys the possibility of the emergence of the higher. And the more that the lower flowers, the more that the higher can flourish.
Grasping this finality within marriage sets up a heuristic that allows one to explore marriage in a differentiated and integrated way. The differentiation is over the different generic levels of reality as sublated within human historical process. As integrated, these provide the mode of inquiry into the relations of higher and lower orders of intelligibility as well as the potency for new types of operations and new levels of conscious life. In this 1943 essay, Lonergan introduced this heuristic first so that he could then suggest specific ways to explore the meaning of marriage.
