Imagination

“Imagination” is said in at least three major ways. Aristotle minimalistically characterized phantasia as a production of images that both plays a role in our experience of sense perception and can operate independent of it, as in dreaming. Spinoza treated imagination as kind of a passive belief. For him, this was strongly associated with common illusions and wishful thinking – especially with regard to our status as agents — in ordinary life. The Romantics identified imagination with creativity.

Beatrice Longuenesse in her marvelous Kant and the Capacity to Judge has developed in detail Kant’s argument that the same basic “categories” used in reflective thought are already implicit in our pre-reflective apprehensions of things in what Kant called a synthesis of imagination. I think this means not that the Kantian categories have some pre-given or metaphysical status, but rather that for the kind of beings we are, even “pre-reflective” apprehensions have some dependency on previous reflective apprehensions. We are never either entirely active or entirely passive. (See also Passive Synthesis, Active Sense; Voluntary Action; Middle Part of the Soul.)

Richard Kearney in On Paul Ricoeur: The Owl of Minerva nicely develops Ricoeur’s view that imagination is not so much a special way of seeing as “the capacity for letting new worlds shape our understanding of ourselves…. This power would not be conveyed by images, but by the emergent meanings in our language” (quoted in Kearney, p. 35). According to Kearney, Ricoeur associated imagination first and foremost with “semantic innovation”. What Aristotle in a different context called “searching for a middle term” is an aspect of this creativity with respect to meaning.

The Greek root for “poetry” (poiesis) fundamentally means making or doing in a much more general sense. The Romantics added a stress on innovation, which they saw as coming from the inner depths of the soul. Ricoeur’s treatment of imagination as fundamentally involving the emergence of new meaning nicely takes up the Romantic stress on imagination as innovation, without depending on the Romantics’ dubious metaphysical psychology of interiority.

What We Really Want

Aristotle distinguished willing from unwilling actions, noting that there are mixed cases in which we do something we ordinarily would not do, in order to avoid a greater evil or to further a greater good. Hegel suggested that what we actually do is the best guide to understanding what we really want. Does this make Aristotle’s distinction meaningless? I want to say no.

It may be that Hegel would reject Aristotle’s secondary distinction between unwilling actions and mixed cases. Hegel might even say that all of Aristotle’s “willing” and “unwilling” actions are better thought of as mixed. Paul Ricoeur has somewhat similarly argued that agency always involves a combination of active and passive aspects.

Aristotle said that we should either judge mixed cases by the particulars of the relevant tradeoffs, or simply consider them as occasions calling for forgiveness. I think this is compatible with Hegel’s perspective. What we actually did in some situation is not necessarily the key to what we really wanted, full stop, but rather the key to what we really wanted under the applicable conditions. (See also Context; Rethinking Responsibility; Brandomian Forgiveness.)

Formal and Informal Language

Paul Ricoeur suggested that more formal kinds of explanation and informal understanding are related to one another by the first playing a mediating role in the second, and used this in a very nice reconciliation of Aristotelian and Kantian ethics. From the formal side, the mathematician Haskell Curry — whose work has greatly influenced the theory of programming languages — argued in the 1950s that the ultimate metalanguage for all formal languages can only be ordinary natural language. Amid the tremendously rich development of formal languages in the 20th century, this point got somewhat lost, but more recently Robert Brandom’s expansion of Wilfrid Sellars’ work on material inference has provided a detailed account of how this works. The circumscribing role of informal natural language in all formal developments is related to the great Kantian insight of the primacy of practical over theoretical reason.

Aristotelian Probability

Things Aristotle calls “probable” have nothing to with statistics. The legal notion of “probable” cause is much closer to Aristotle’s concept of probability. It refers to conclusions for which there are good reasons, but which are not expected to be established beyond reasonable doubt.

Mathematics achieves certainty and rigorous necessity through the artifice of abstracting away real-world complication and ambiguity. Whenever we are concerned with the real world as we actually experience it, whatever conclusions we reach at best follow probably rather than necessarily.

Keeping in mind the probable character of judgment in general should not prevent us from acting decisively. This kind of “probability” is all the basis we need to have well-founded practical confidence. We can have strong confidence without false pretenses of certainty.

To claim certain knowledge in these cases amounts to what Kant called dogmatism. The deep roots of American pragmatist philosophy have more to do with something like an Aristotelian emphasis on the practical sufficiency of probable judgments than with later reductive, utilitarian theories of value. (See also Aristotelian Dialectic; Dialectic Bootstraps Itself; The Epistemic Modesty of Plato and Aristotle; Demonstrative “Science”?; Kantian Discipline; Copernican.)

Multiple Explanations

One of the great strengths of Aristotle’s approach to things is the way it makes use of multiple, complementary kinds of explanation. The paired modalities of actuality and potentiality and the four “causes” (ends and means, form and materiality) all interweave together to create rich tapestries of understanding. Aristotle famously said that to know is to be able to explain, and his notion of explanation is clearly hermeneutic and expansive, rather than reductive. (See also Interpretation; What and Why.; Difference; Classification; Definition.)

First Principles?

The works of Aristotle as they have come down to us include what seem to be nearly opposite statements about the knowledge of first principles. Book 1 of the Topics, Aristotle’s treatise on dialectic, says that dialectic, which assumes no pre-existing truth and does not yield certain conclusions, turns out to be the best way to the investigate first principles.

However, striking a much more Platonic note, book 1 of the Metaphysics says that knowledge of first principles or “wisdom” is the most difficult of all, but is also the most exact kind of the knowledge in the strong sense that is often translated as “science”. This is said to include knowledge of goods or ends, along with other sorts of causes. But then again, book 1 of the Nicomachean Ethics insists that ethics and the practical judgment associated with it are necessarily inexact. This latter difference seems to have to do the status of first principles as universals, in contrast to the concern of ethics with particular actions.

While book 1 of the Metaphysics is a beautiful text with many valuable insights, the idea that knowledge of first principles could be what is most exact seems incongruous to me. It seems to assume an unequivocal priority of universals over particulars, whereas I think the overall balance of Aristotle’s work shows a much more even-handed view. The ethics, the dialectic, the biological works all take a more nuanced approach. My favorite part of the diverse collection that is the Metaphysics is the very dialectical part in the middle about substance, potentiality, and actuality. (See also Interpretation; What and Why; First Principles Come Last.)

Hermeneutic Biology?

Aristotle’s biological works are quite fascinating and lively. They contain abundant experiential reports, including some hearsay, intermixed with thoughtful reflection. Ultimately it is the reflective aspect that gives them their enduring value.

Sometimes, the content is surprising. For instance, book 1 of Parts of Animals is the place where he thoroughly criticizes the notion of classification by dichotomy. With concrete illustrations from the animal kingdom, he shows that commonly recognized kinds cannot be arrived at by successive dichotomous distinctions. Aristotelian distinction is n-ary rather than binary, pluralist rather than dualist.

Elsewhere (Metaphysics 982b) he famously said that philosophy begins in wonder. At Parts of Animals 645a, he added, “We therefore must not recoil with childish aversion from the examination of the humbler animals. Every realm of nature is marvelous: and as Heraclitus, when strangers who came to visit him found him warming himself at the furnace in the kitchen and hesitated to go in, is reported to have bidden them not to be afraid to enter, as even in that kitchen divinities were present, so we should venture on the study of every kind of animal without distaste; for each and all will reveal to us something natural and something beautiful. Absence of haphazard and conduciveness of everything to an end are to be found in natures’s works in the highest degree, and the end for which those works are put together and produced is a form of the beautiful” (Complete Works, revised Oxford edition vol. 1, p. 1004; see also Natural Ends; Sentience).

Searching for a Middle Term

“But nothing, I think, prevents one from in a sense understanding and in a sense being ignorant of what one is learning” (Aristotle, Posterior Analytics; Complete Works revised Oxford edition vol. 1, p. 115). The kind of understanding spoken of here involves awareness “both that the explanation because of which the object is is its explanation, and that it is not possible for this to be otherwise” (ibid). To speak of the “explanation because of which” something is suggests that the concern is with states of affairs being some way, and the “not… otherwise” language further confirms this.

Following this is the famous criterion that demonstrative understanding depends on “things that are true and primitive and immediate and more familiar than and prior to and explanatory of the conclusion…. [T]here will be deduction even without these conditions, but there will not be demonstration, for it will not produce understanding” (ibid). The “more familiar than” part has sometimes been mistranslated as “better known than”, confusing what Aristotle carefully distinguishes as gnosis (personal acquaintance) and episteme (knowledge in a strong sense). I think this phrase is the key to the whole larger clause, giving it a pragmatic rather than foundationalist meaning. (Foundationalist claims only emerged later, with the Stoics and Descartes.) The pedagogical aim of demonstration is to use things that are more familiar to us — which for practical purposes we take to be true and primitive and immediate and prior and explanatory — to showcase reasons for things that are slightly less obvious.

Independent of these criteria for demonstration, the whole point of the syllogistic form is that the conclusion very “obviously” and necessarily follows, by a simple operation of composition on the premises (A => B and B => C, so A=> C). Once we have accepted both premises of a syllogism, the conclusion is already implicit, and that in an especially clear way. We will not reach any novel or unexpected conclusions by syllogism. It is a kind of canonical minimal inferential step, intended not to be profound but to be as simple and clear as possible.

(Contemporary category theory grounds all of mathematics on the notion of composable abstract dependencies, expressing complex dependencies as compositions of simpler ones. Its power depends on the fact that under a few carefully specified conditions expressing the properties of good composition, the composition of higher-order functions with internal conditional logic — and other even more general constructions — works in exactly the same way as composition of simple predications like “A is B“.)

Since a syllogism is designed to be a minimal inferential step, there is never a question of “searching” for the right conclusion. Rather, Aristotle speaks of searching for a “middle term” before an appropriate pair of premises is identified for syllogistic use. A middle term like B in the example above is the key ingredient in a syllogism, appearing both in the syntactically dependent position in one premise, and in the syntactically depended-upon position in the other premise, thus allowing the two to be composed together. This is a very simple example of mediation. Existence of a middle term B is what makes composition of the premises possible, and is therefore what makes pairings of premises appropriate for syllogistic use.

In many contexts, searching for a middle term can be understood as inventing an appropriate intermediate abstraction from available materials. If an existing abstraction is too broad to fit the case, we can add specifications until it does, and then optionally give the result a new name. All Aristotelian terms essentially are implied specifications; the names are just for convenience. Aristotle sometimes uses pure specifications as “nameless terms”.

Named abstractions function as shorthand for the potential inferences that they embody, enabling simple common-sense reasoning in ordinary language. We can become more clear about our thinking by using dialectic to unpack the implications of the abstractions embodied in our use of words. (See also Free Play; Practical Judgment.)

Dialectic Bootstraps Itself

Here is a subtle but vital point. I’ve just reiterated that dialectic assumes no prior truth. Dialectic approaches coherence in an iterative and incremental way, sometimes backing up and trying a new path. As a philosopher in what I take to be the genuine spirit of Plato and Aristotle, I think seriously taking up such a work is the very best we mortals can honestly do to achieve high levels of practical confidence about the things that matter most in life. No, it does not have the precision or definitiveness of mathematics, but mathematics is like Aristotelian demonstration in that all it tells us with certainty is that certain conclusions follow from certain premises, so the conclusions are only as applicable to life as the premises and their assumed mapping to the real world.

The vital point is that dialectic — the development of richer meaning — can make real progress, without ever assuming a foundation. No, we’ll never say the last word, but we can iteratively and incrementally build cumulative results. With iterative and incremental development of coherent articulations of what we care about and an openness to acknowledging error, we can progressively improve interpretive confidence.

I think this is what is behind Hegel’s somewhat mystifying talk about spirit producing itself. (See also Interpretation; Dialogue; Ethical Reason; Practical Reason; The Autonomy of Reason; Openness of Reason; Reason, Feeling.)

Demonstrative “Science”?

The “historiographical” notes on the history of philosophy I offer here from time to time are a sort of compromise. For much of my life, I’ve been very concerned with the fine grain of such history, and with casting a broad net encompassing many historical figures. Here, I made a strategic decision to focus instead on a mere handful of philosophers I consider most important.

Discussion of actualization in Hegel led to actualization in Aristotle, which led me to indulge my fascination with the Aristotelian commentary tradition. To the extent that it is possible to generalize about the historic readings discussed in the Greek, Arabic, Hebrew, and Latin commentaries, my own view of Aristotle is quite different on a number of key points, having more in common with some modern readings. Nonetheless, I am enormously impressed by the levels of sophistication shown by very many writers in this tradition.

I just mentioned al-Farabi again. As previously noted, al-Farabi (10th century CE) played a great historic role in the formulation of Arabic (and consequently, Hebrew and Latin) views of Aristotle. The Syrian Christians who did the majority of the translating of Aristotle to Arabic from Syriac had access to most of Aristotle’s works, but publicly only taught from the logical treatises. It was al-Farabi who initiated public teaching of the full range of Aristotelian philosophy in the Islamic world. He flourished during the so-called Islamic golden age, a time of tremendous interest in ancient learning not only by aristocrats but by many literate skilled crafts people. The political climate of the Islamic world at the time was much more embracing of secular learning than it came to be between the 13th and 19th centuries CE.

One unfortunate aspect of al-Farabi’s reading was a very strong privileging of a notion of demonstrative “science” over Aristotle’s own predominant use of dialectic in philosophical development. This was based on a reading of Aristotle’s Posterior Analytics as propounding a model of “science” as a deductive enterprise expected to result in certain knowledge, which is still dominant today, but which I (following a number of modern interpreters) think involves a misreading of the basic aims of Aristotelian demonstration.

The idea that Aristotle was fundamentally concerned to develop “sciences” yielding certain knowledge gave a more dogmatic cast to his whole work, which has been a contributing factor in common negative stereotypes of Aristotle. Many modern commentators who still accept this reading of Posterior Analytics have been puzzled by the huge gap between this and Aristotle’s actual practice throughout his works, which in fact is mainly dialectical. I think a careful reading of the Topics (on dialectic) and Posterior Analytics (on demonstration) with consultation of the Greek text on the originals of some key phrases yields a view that is far more consistent with Aristotle’s actual practice.

Demonstration is a pedagogical way of showing very clear reasons for certain kinds of conclusions. It works by assuming some premises are true, whereas dialectic makes no such assumption. Thus the only necessity that results from demonstration is the “hypothetical” one that if the premises are true, then the conclusion is also true. But the more important point in regard to the classic syllogistic form is that the common “middle term” that allows the major and minor premises to be both formally and materially composed together illuminates why we ought to consider it appropriate to assume the conclusion is true if we believe the premises are true.

Dialectic, as I have said, is cumulative, exploratory discursive reasoning about meanings in the absence of initial certainty. This is how Aristotle mainly approaches things. Dialectic implicitly relies on the same logical form of syllogistic argument explicitly used in demonstration, but Aristotle distinguishes dialectic and demonstration by whether premises are treated as hypotheses to be evaluated, or as hypothetically assumed “truths” to be interpreted.

It is also important to note that in the Latin scholastic tradition, the dogmatic trend resulting from wide acceptance of claims about demonstrative science was significantly mitigated by a strong counter-trend of evenhandedly analyzing arguments pro and con, which effectively revived a form of dialectic.
