Life: A Necessary Concept?

Hegel argues that we ultimately cannot explain intelligibility without presupposing Aristotelian/Kantian “internal” teleology, which in turn requires the concept of the distinction between living and nonliving beings.

With nonliving beings, events simply happen. A piece of iron may rust, for instance, and that is that. It is still iron.

A living being, however, is always subject to a normative comparison to its concept. For Hegel, a plant that is dying of thirst is a “failing” instance of what it is to be a plant. There is no comparable status for the rusting piece of iron.

Mechanistic explanation offers an allegedly complete system of causality. But for Hegel, it raises the same “problem of indifference” that the logic of being encountered.

In a similar kind of move to what he has been doing in the Logic as a whole, Hegel argues that mechanism implicitly presupposes a more comprehensive kind of explanation, that it cannot really solve its own problems when it is pursued as the only valid form of explanation. He then considers in succession “chemism”, which additionally takes into account internal properties of materials that affect how they may combine with one another; “external” teleology applicable to artificial things, which explicitly presupposes a designer; and finally the immanent “internal” teleology considered by Aristotle and Kant.

Pippin dwells extensively on the similarities and differences between Kant and Hegel in this area. On the Kantian side, this involves an important evolution of Kant’s thought that occurred while he was writing what became the Critique of Judgment.

“In early 1789 Kant began to formulate the new problem of reflective judgment, as well as a new a priori principle for such a faculty, the purposiveness of nature. What is important to notice for our purposes is that with that development, the shape of the entire critical project began to change dramatically” (Hegel’s Realm of Shadows, p. 290).

“Kant had realized that something like the deep structure of judgments like ‘this rose is beautiful’ actually contravened its own surface structure, that the predicate ‘beautiful’ was not really functioning as a standard predicate, as it appeared to. It referred to no objective property or mere secondary quality. Instead, he concluded, it involved a nonconceptually guided reflective activity on the part of the subject of the experience, whose novel logic required notions like a free play of the faculties, purposiveness without a purpose, disinterested pleasure, a commonsense and universal subjective validity” (pp. 290-291).

“The realization of the distinct features of this reflective activity was only the beginning of a series of more strikingly novel claims of interest to us…. [T]he reflective judging that resulted in aesthetic judgments, also constituted the basic structure of teleological judgments, and so could account for the unique intelligibility of organic beings” (p. 291).

“And then a number of other issues seem to be thrown into the same reflective judgment pot. The formulation of scientific theories not fixed or determined by empirical generalizations involved this activity and its logic, as did the systematizing of empirical laws necessary for genuine scientific knowledge. Finally, even the determination of ordinary empirical concepts now seemed to require this newly formulated reflective capacity…. So reflective judging and its a priori principle were now necessary not only for explaining the possibility and validity of aesthetic judgments, but in accounting for the necessary distinction between organic and nonorganic nature, the formation of empirical concepts, the proper integration of genera and species, the general unification of empirical laws into systems of scientific law, theory formation itself, and the right way to understand the attribution of a kind of necessity to all such principles, judgments, concepts, laws, and systems” (ibid).

“Kant continued to hold that such reflective judging was not constitutively necessary for there being objects of experience at all, and so could not be properly called cognition…. But Kant himself seems to be conceding that that result alone leads to an impoverished notion of cognition…. We wouldn’t know much… without empirical concepts, laws, systems, and distinctions between living and nonliving. So all the above products of reflective judgment must count as indispensable, and in a way that is not just convenient, but nevertheless remains merely regulative” (p. 292).

“Given their necessity and indispensability, given how much we would miss in the world if we could not claim to know that things fall into kinds (that there are empirical concepts), that nature is law-governed with necessity, that species fall under genera, and that some beings are alive, the Hegelian question is: Why does Kant persist, even after the expansion of his system in the third Critique, in claiming that we do not really know any of these things, that we just require them of ourselves and can’t see a way to abandon such commitments?” (ibid).

Kant seems to have held that in spite of its value for subjective understanding, teleology stands in conflict with scientific explanation; that the only objective causality is efficient causality; and that an objective teleology would imply a sort of “backwards” determination in time. Hegel contests all of this.

“For Kant, a living being requires us to think something we cannot, how the whole causes the parts that cause it” (p. 293).

Pippin, like Kant, seems to regard the last formulation as a reduction to absurdity. But he himself notes that in biological reproduction, parts and whole are produced simultaneously. And many processes in nature work by a kind of feedback, which involves circular dependencies that play out over time in an alternating or simultaneous way.

“[J]ust as Kant did not attempt to deduce the necessary existence of events in causal relations, but sought to show that any event that did exist must stand in a necessary relation to some prior event, and just as Kant did not try to deduce the necessary existence of living beings, but tried to show that any world that required mechanistic explanations of what exists, or any world in which change is a matter of efficient causation, must also allow, cannot rule out, that there are changes like gestation, birth, growth, reproduction, disease, and death, which cannot be accounted for by the logical form appropriate for nonliving beings, so Hegel is not out to deduce a priori the necessary existence of living beings, but has an ambition similar to Kant’s… but much greater because Hegel denies that teleological explanations are merely subjectively necessary” (p. 274).

“In terms of the logic of the Concept where the concept of life appears, [Hegel] means to show that there could not be adequate mechanistic and chemical and ‘external’ teleological explanations (say, the production of an artifact guided by a maker’s representation) without the contrasting distinction with living beings, without, following Kant, ‘internal’ teleology. (That is, a case where an element is for the sake of the whole without its being the — impossible — case that the element or part intends to be for the whole, and without reference to any designer’s intention.) His unusual thesis is that teleology is ‘the truth of mechanism’. That is, mechanistic explanations are domain specific, and so represent an abstraction from a more comprehensive and complex domain that includes subjective or intentional teleology and objective teleology in organic beings” (pp. 275-276).

“For Hegel, … the conceptual forms required for the unity of judgment are, at the same time, the forms necessary for any object determinacy. The forms of thought are the forms of being” (p. 276).

This is not because thought has magic powers, but because of the kind of thing that being has turned out to be in the investigations of the Logic. In my estimation at least, Hegel has convincingly shown that true being is inseparable from meaning and intelligibility. It is not some dumb and arbitrary “existence”.

“Life is said to be the ‘immediate’ manifestation of the Idea” (p. 277).

What this means is that “Life will reveal at an initial level the true unity of subjectivity and objectivity. This is said in the sense in which even plants, for Hegel, have ‘subjectivity’ even as objects. Their growth and nutrition cannot be comprehended adequately as just the product of mechanical forces. Each can be said to ‘direct’ the course of its life as it requires; each has an inner distinct from an outer, where this does not just mean inside as opposed to outside its surface” (ibid).

It was not clear to me that the Idea would even have an “immediate manifestation”. At this point, the Idea seems to me to be something that in itself would be purely mediate, even though experience always involves an element of immediacy. But at least within a human subjectivity, something purely mediate can always be represented, and the representation in itself does have a kind of immediacy. This case is a little different, but the argument that a plant has a kind of rudimentary “subjectivity” while also being a kind of object does, I think, suggest a way of understanding this simultaneous subjectivity and objectivity that could be seen as a simple instance of the union of subjectivity and objectivity that characterizes the Hegelian Idea.

“[H]aving shown the truth of the object in self-consciousness, in conceptuality, Hegel proposes to investigate the concept in that status, now understood as being-true, or in its being the ground of the intelligibility of the object. As he says, now ‘the concept determines itself as objectivity’…. This begins after a consideration of the concept in its formality, in the structure of concept, judgment, and syllogism. This then suggests the question of the world of objects, of ‘the truth’, of being-in-and-for-itself, already reflected in the truth-preserving inferential structure of such a syllogistic. To have reached this stage, presupposing everything that has gone before, is to see the logic of the relation among concepts in judgments and of judgments in inferential syllogistic relations as comprehending objects and their interrelations as explicable in a system” (p. 278).

This kind of use of “system” simply expresses the coherence in real intelligible being, and does not have the objectionably pretentious character that was all too common in talk of philosophical “systems” in Hegel’s Germany. Since Hegel does use “system” in this more benign and substantial sense, I am inclined to be forgiving of his rhetorical participation in the enthusiasm for philosophical “systems”.

“At such a point, we will have fleshed out considerably the ‘object’s being its concept’ in a much fuller logical system of judgmental interrelations, systematically, and a modally robust one, prescribing what must and cannot happen under this or that condition. In this fuller systematic picture, we need a determinate characterization of the norm, comprehensibility, as such. Such a norm or pure concept of genuine understanding will tell us what a thing is in terms of its relevant relational properties” (pp. 278-279).

With the concept, we have explicitly entered the territory of normativity. A concept for Hegel is never just a representation. Every Hegelian concept has a normative character.

“That determinate norm of comprehensibility is what is introduced by the pure concept Mechanism — more broadly in the claim that true comprehensibility is and is only mechanistic, paradigmatically Newtonian mechanics. Yet again, it is this sort of overreach that reveals the limitations and incompleteness of such a norm of comprehensibility. This is the first, immediate, simplest manifestation of the a priori claim to a norm for determinate explicability…. This is essentially a ‘billiard balls’ model of moving and inertial forces, in which there is what Hegel continually calls ‘an indifference’ in the relation among objects. And therein will lie its chief problem” (p. 279).

The concept of mechanism now shows a dynamic very similar to what we saw before with the concept of Being. In both cases, Hegel wants to extract as much insight and value as possible from their respective failures.

“That is, the indifference of objects external to each other, or comprehended only as matter moving and colliding in space, means there is no real explanation of what happens, just a formalization of what happens. There is no way (except pragmatically or ‘subjectively’ for Hegel) to select in or out the relevant relations among such indifferent objects, and we will find instead that we are awash in infinite contingency, with no real ground for our isolation of the relevant units of comprehension” (pp. 279-280).

“Chemism does make such an appeal to internal properties, the chemical properties, to explain why some chemical compounds are possible and others are not. Objects considered chemically are not ‘indifferent’ but determine their relationality as dependent on the kind they are” (p. 280).

“When we say that average acceleration over a period of time is its change in velocity divided by the duration of the period, or when we say that the hydrogen and oxygen molecules combined to form water, or when we say that that clock functions poorly, or that wolf is deformed, these are not empirical distinctions within a common notion of comprehensibility. In Hegel’s language, they are objective aspects of the logical distinctions between immediacy, mediation, and self-mediation necessary for all objective intelligibility” (p. 281).

Hegel in the Logic aims to develop a kind of universal logical meta-language for explaining the more concrete concepts we use to explain the world.

“A living being’s concept is not external to it as a particular being. That particularity is essentially nothing other than the becoming of its concept. The concept is internal to its nature, and that nature is self-determining, not determined from without. (Hence the claim that life is the first, immediate manifestation of the Absolute Idea, the unity of subjectivity and objectivity.)” (ibid).

“Now, a simple way to sum all of this up, however misleading, would be to say that for Hegel life is an objectively necessary pure concept because we know that mechanism is such a concept, and that chemism is, and that artifactual teleology is, and that these pure concepts are incomplete without teleological concepts, ultimately the concept of living organisms” (p. 282).

“As we have already seen, Kant distinguishes, and Hegel praises him for doing so, between an element in a complex that is purposive because it satisfies the ends of the designer or maker, like a radiator in a car, or external purposiveness, and an element the purposiveness of which is determined not by any appeal to an external designer, but rather ‘internally’ in an organic self-organizing and self-maintaining whole. We explain the parts by reference to this whole, which itself is, reciprocally, the reason the parts are as they are; and all of this without any intention of the parts, such as organs, to represent anything as their end. So, for example, we can say what leukocytes, white blood cells, are for, without reference to a designer of the system, but by reference to the internal ends of the living being, such as maintaining health by attacking foreign invaders like bacteria or parasites. As Kant says, we can show that the parts of a living being ‘as far as their existence and their form are concerned are possible only through their relation to the whole'” (pp. 283-284).

“But, again, [for Kant] this is all a matter of what we must think for the sake of a satisfying explanation…. It must be merely that because… teleological causality makes no sense in the scientific terms Kant considers himself to have established…. ‘Strictly speaking, therefore, the organization of nature has nothing analogous to any causality known to us'” (p. 284).

“But all of this is supposed to be consistent with the unavoidability of teleological explanations, that is, with their necessity…. He asserts as a philosophical truth that we will never be able to [reduce life to mechanistic principles], and even that it is ‘absurd’ to imagine that we could. (No ‘Newton for a blade of grass’, ever.) He says clearly that we can no more give up the teleological principle and the idea of final causality than we could give up the universal causal principle itself” (pp. 284-285).

“One brief reason [Kant] gives for this is that this abandonment would leave us without anything ‘for guidance in observing’…. While we have the possibility of a physical and chemical account of cell division, we are not observing a mere series. With that account alone, we would have no way of understanding that these processes are part of one series, no way to isolate anything like ‘what comes next’ and so no language to explain what happens when it does not” (p. 285).

“What [Hegel] tries to show is that mechanism as a principle, as a pure or logical principle…, already amounts to, implicitly, what is most distinctive about teleology, an ‘explanation by concept’, how a thing ‘matches up’ to its concept, although in mechanism this concept is only ‘in itself’, not ‘for itself’…. [H]is claim is that while mechanism posits a radical independence among objects in motion, the results of mechanism itself reveal a regular dependence, fixed and unvarying, among such putative independent objects, and it must transform itself into a position that can do this justice, not treat it as an astonishing accident” (p. 288).

Final installment in this series: The Logic’s Ending

Spontaneity

Spontaneity has a technical meaning in Kant and Husserl that is at odds with common usage. In ordinary speech, we are said to do something “spontaneously” when we do it on the spur of the moment, without a previous plan. But Kant and Husserl call everything guided by reason “spontaneous”, even though reason is involved with conscious deliberation and thinking things through.

According to an older usage, things in nature were said by some to occur “spontaneously” when they had no discernible cause. In the scholastic tradition, others argued that “nothing comes from nothing”, and rejected the assumption that things with no discernible cause really happen without a cause, as was purported to occur in what was called “spontaneous generation”.

Leibniz embraced and codified the “nothing from nothing” argument as the principle of sufficient reason. The principle of sufficient reason does not itself imply the kind of particular providence associated with the popular expression “everything happens for a reason”. It just says that everything has some kind of reasonable explanation, not that what we subjectively perceive as cosmic injustice is part of a divine plan, even though Leibniz separately argued for that as well.

Of course, it matters a lot what kinds of causes or reasonable explanations we recognize. In Leibniz’s time, the notion of cause had already been greatly contracted by early modern writers, who further transformed the late scholastic notion of efficient cause in a mechanistic direction, while accentuating the late scholastic tendency to reduce all other causes to efficient causes. Leibniz himself recommended the use of only mechanistic explanations in natural science, but did not see natural science as all-encompassing, and defended the use of teleological explanation in broader philosophy. He compensated for the narrowness of mechanistic causality by speaking of sufficient reason rather than sufficient cause, and kept a place for form and ends as reasons.

Kant ultimately also defended a kind of teleology, especially in biology and in his account of beauty, but he was much more reserved about using it in general explanation than Leibniz, due to his scruples about grounding all “theoretical” explanation in experience. However, he assigned all ethical matters to a separate “practical” domain, which he wanted to exempt from the kind of narrow causal explanation that he considered the norm for physics, and he argued that for us humans, “practical” reason is more fundamental.

Human action for Kant belongs to the practical domain, which he famously argued is governed by “spontaneity” and “freedom”. I now think “spontaneous” and “free” for Kant simply mean not subject to mechanistic explanation. Thus insofar as we are positively motivated by moral imperatives or values, he would say we act spontaneously and freely. I think he also believed that all human thinking is ultimately motivated by ultimate ends, and therefore called it spontaneous and free.

Kant confused generations of scholars by borrowing voluntaristic rhetoric, which he did with the aim of emphasizing that human thought and action are not reducible to mechanistic physics. But freedom and spontaneity in Kant do not mean arbitrariness, as they effectively do for defenders of voluntarism. Rather, they are meant to allow room for positive motivation by moral imperatives or values.

Another confusing move Kant made was to argue for a special “causality of freedom” that he never explained adequately. Due to its contrast with physical causality, it sounded at times like a kind of supernatural break in the natural order he otherwise recognized. Many commentators thought Kant contradicted himself in arguing both that the natural order is self-contained and that there is a separate causality of freedom. I think these problems are ultimately explained by the narrowness of the mechanical concept of causality in nature. The “causality of freedom”, I want to say, simply means motivation by moral imperatives or values rather than by impulse. Kant considered impulse to be within the realm of natural-scientific causality, and therefore opposed it to spontaneity, whereas contemporary common usage associates “spontaneity” with acting on impulse.

(Aristotle, with his much broader notion of cause that essentially identifies causes with any kinds of “reasons why”, would treat values and moral imperatives as one kind of final causes, or what I have been calling “ends”.)

Husserl’s way of speaking about these matters is to contrast human motivation with causality. For him, “causality” is exclusively the causality of modern physical science, but human thought and action are to be explained by “motivation” rather than causality. Husserl’s use of “spontaneity” is related to that of Kant, and applies to everything that he explains in terms of motivation. (See also Kantian Freedom; Kantian Will; Allison on Kant on Freedom; Freedom Through Deliberation?.)

Observing Reason

Hegel had suggested that a Fichtean idealism ends up attempting to fill out its extreme abstraction by ad hoc adoption of a complementary Lockean empiricism. He goes on to treat something like Lockean empiricism, under the title of “Observing Reason”. The bulk of Hegel’s discussion ends up focusing on the empirical study of organic nature, with brief remarks on attempts to define psychological “laws of thought” and other psychological “laws”. Then he turns to physical anthropology, polemicizing at length against the old pseudo-sciences of physiognomy and phrenology, which purported to make predictions about human character from body types and skull shapes. Here we also reach the end of the first volume of Harris’ commentary on the Phenomenology, subtitled “The Pilgrimage of Reason”. The concluding second volume will be “The Odyssey of Spirit”.

Hegel dwells at length on the concept of organism, taking up Kant’s practical vindication of Aristotelian teleology in biology. The unity of an organism has to do with a pure “purpose” internal to the organism. None of its particular observable characteristics turn out to be essential in themselves; rather, they all have a fundamentally relational character. In Force and Understanding he had argued that mathematical physical law is purely relational; here he treats an organism as a purely relational unity held together by an internal “purpose”. Force and Understanding had been concerned with the formal unity of the physical world; the notion of organism introduces the notion of individuation within a world. Hegel picturesquely says that animals actively individuate themselves — distinguish themselves from the surrounding world — by means of their teeth and claws. By comparison, plants in their “quiescence” have only a minimal kind of individuality. Previously, he had quipped that animals must be unimpressed by the putative separateness of objects, because without ceremony they fall to and gobble them up.

Harris says in his commentary, “Observing Reason is a ‘return’ of Sense-Certainty and Perception together, because it is concerned with the ‘essence’ of real things. It wants to conceptualize them, but it is naive, like the Understanding” (Hegel’s Ladder I, p. 474).

“Locke’s standpoint differs from that of Sense-Certainty and Perception, both because he insists that the mind can know only its own ideas, and because what he calls the ‘plain historical method’ is a descriptive technique that aims to uncover the universal laws and principles of rational epistemology” (p. 475). The world is “stripped” to the pure concept of “matter or extension” (p. 476). “Here at the beginning we are faced by a Reason that wants to know not itself, but the world of things” (p. 477).

In the context of organic nature, “[Hegel] is now going to show us that the Kantian concept of mathematical schematism (which is a direct descendant of Gailleo’s distinction [between primary and secondary qualities of bodies]) fails completely as a bridge between the observed data and the conceptual structures used by the scientific ‘observers’. The observing consciousness of Reason itself is now going to learn what we learned when we observed the perceptual consciousness. It will learn that the thing is a Hegelian concept, (not a Galilean or Lockean one). The consciousness we are observing will discover that the [Galilean or Lockean “thing”] cannot correspond to Reason because it is essentially and necessarily dead” (p. 478).

(I confess I don’t recognize the reference to Kantian “schematism” as mathematical; I think of Kantian schematism more generally as a mediation between sensible “intuition” and conceptual thought through imagination.)

“Everywhere it observes things; but what it seeks is their Concept, or the law of their behavior…. It will observe first the natural world, then itself (as subjective spirit); and finally it will observe the relation between subjective spirit and its natural embodiment. But because the object of observation must always be a stably inert Gestalt, an observable thing, the results achieved become less satisfactory at every step” (pp. 478-479).

“[T]he ‘immediacy’ of the standpoint means that we are not observing it in the proper way…. Consciousness must first descend ‘into its own depth’. Thinking must discover what it is, as an activity; it must discover the dialectical logic that is its own ‘living spirit'” (p. 479). But this is only a beginning.

“The logical priority of ‘consciousness’ as the ‘own proper shape’ of Reason can only be established by the reductio ad absurdum of the alternate route through ‘things’. It must be established in this way, because the structure of ‘consciousness’ determines that Reason will naturally begin by trying to find itself in ‘things’…. Hence it is part of the object of the present chapter to show that we cannot make a direct descent into the depths of consciousness as subjectivity. If we try to do this (as Kant and Fichte did) what we discover is only an abstract essence of Reason that is perfectly valid, but almost completely useless. Its only real use will be to serve as the guiding light for the subsequent descent into the depths of our cultural world. We have to experience both the quest for the ‘essence of things’ and the quest for the ‘essence of consciousness’ before we can properly embark upon the discovery of the self in its thing-world” (ibid).

Harris develops Hegel’s distinction between inert “representations” of “things” and active thought. “The controlling conception in Hegel’s mind is the self-individuation of the Aristotelian form” (p. 486).

In this context of organic nature, Harris notes Hegel’s general preference for Plato and Aristotle over Newton, and thinks Hegel also takes from Aristotle the less fortunate view that nature has no history. I take Aristotle’s remarks about the “eternity” of species, the motions of the stars, etc., as having the valid pragmatic sense that such things had not been observed to change within living social memory. (I note also that Plato in the Laws already suggested that organic species do in fact come to be and perish.) Hegel defends Aristotelian “internal” teleology, while rejecting both the biological mechanism of Descartes and the “external” teleology of the argument from design used by Newton and others. Purposefulness for Hegel does not presuppose a mind (p. 502).

In spite of his criticisms of philosophical empiricism, Hegel defends the importance of empirical verification of hypotheses. Harris actually calls Hegel a “spiritual empiricist” in both natural science and ethics (p. 490). He says that Hegelian “necessity” is neither physical nor formal, but “logical” in Hegel’s sense. Hegel is much more concerned to criticize the “formalism” of philosophies of nature developed by followers of Schelling than actual scientific work.

In spite of the importance of “Life” in contrast to “dead” things in Hegel’s view, he has no use for vitalism. “Life is not more on the ‘inside’ of the organism than it is on the ‘outside’…. It is the ‘general fluidity’ within which the parts and organs of the body are formed and dissolved…. Observing Reason makes the Newtonian mistake of granting priority to visible stability” (p. 507). Hegel discusses notions of “sensibility” and “irritability” current in the biology of his time, adding in his own notions of “fluidity” and “elasticity”. He is very skeptical about “laws” in biology.

Between remarks on zoology and psychology, Hegel briefly (and dismissively) discusses so-called “laws of thought”. These relate to the early modern tradition of psychologizing in logic. With somewhat different motivation, Hegel anticipates Frege and Husserl’s rejection of such “psychologism”.

He also has no use for early modern psychology. In Harris’ summary, “Observational psychology operates with a mechanical toy that is all in pieces, so that the soul is observed and discussed like a bag full of loose bits” (p. 562). Hegel adds some sympathetic remarks on biography before launching a devastating critique of the now-forgotten pretensions of physiognomy and phrenology to discern purely physical indications of human character. What is important in the last is his general contention that even animal behavior cannot be adequately explained in a purely mechanistic way.

In spite of all of this, the idea of “observing” the objective dimension of a self in its concrete actualization in the world as contrasted with any direct intuition of pure interiority will turn out to have pivotal importance in the development to come. This is in fact how we experience others, and how others experience us. For Hegel it is our shared experience of one another rather than anyone’s private experience that is the basis of ethics. (See also Individuality, Community.)

Next in this series: Toward Spirit

Higher Order

Before and after early modern mechanism and in contrast to it, Plato, Aristotle, Kant, and Hegel all broadly agreed on the normative importance of higher-order things.

In modern terms, Plato’s forms are higher-order things, as distinct from first-order things. Plato trusts higher-order things more than first-order ones, because he considers only higher-order things to be knowable in the sense of episteme, because only higher-order things contain an element of universality, and episteme applies only to universals, not particulars.

Aristotle agrees that higher-order things are ultimately more knowable, but believes it is possible to say more about first-order things, by relating them to each other and to higher-order things; that our initial rough, practical grasp of first-order things can help us to begin to grasp higher-order things by example; and that going up and down the ladder of abstraction successively can help us progressively enrich our understanding of both.

(Incidentally, I have always read the Platonic dialogues as emphasizing the normative importance of acquiring a practical grasp of forms more than specific existence claims about “the forms”. Aristotle’s criticisms make it clear that at least some in the Platonic Academy did understand Plato as making such existence claims, but particularly in what are regarded as later dialogues like Parmenides, Sophist, and Theaetetus, what is said about form seems relatively close to an Aristotelian view. It is even possible that these dialogues were influenced by the master’s even greater student.)

Early modern mechanism completely discarded Plato and Aristotle’s higher-order orientation. Descartes famously recommends that we start by analyzing everything into its simplest components. This temporarily played a role in many great scientific and technological advances, but was bad for philosophy and for people. Hegel calls this bottom-up approach Understanding, as distinct from Reason.

Early and mid-20th century logical foundationalism still adhered to this resolutely bottom-up view, but since the later 20th century, there has been an explosion in the use of higher-order formal concepts in mathematics, logic, and computer science. It turns out that even from an engineering point of view, higher-order representations are often more efficient, due to their much greater compactness.

Leibniz already tried to reconcile mechanistic science with a higher-order normative view. He also contributed to the early development of higher-order concepts in mathematics.

Kant and Hegel decisively revived an approach that is simultaneously higher-order and normative.

Free Will and Determinism

Free will and determinism both represent overly strong claims when applied in an unqualified way. I’ve already written a bit about the evils of voluntarism.

Aristotle’s “cause” or aitia can be any kind of reason why something is the way it is, and a way that something is typically has multiple reasons of different kinds. The modern notion of cause, by contrast, is intended to provide a single, complete explanation of why an event does or does not occur. The modern notion, unlike the Aristotelian one, is univocal. (See also Equivocal Determination.)

In the reception of Aristotle, historically too much attention was paid to the identity of the underlying “something”, as contrasted to the way something is, emphasized by Aristotle himself — to the point where the standard Latin translation for ousia (Aristotle’s main word for a way of being) came to be substantia or “substance” (something standing under). By contrast, the central books of Aristotle’s Metaphysics start from the notion of something persisting through a change and ask what that is, but in addressing that question eventually reverse the order of explanation, and argue that what can best be said to be underlying just is a way that something is actively what it is. An ousia may be expressed in speech as a simple noun, but this is only a kind of shorthand that can always be unpacked into something like an adverbial expression.

In general, Aristotle suggests that we should value ends more than origins. How something turns out is much more important than where it came from.

Already in Neoplatonism, there was a decidedly non-Aristotelian turn toward putting higher value on origins than results, based on the idea that the One was the origin of everything, and nobler than everything. For monotheistic theologians, it was obvious that God as origin was superior to creation.

Aristotle ends up suggesting that what he calls efficient causes — the direct means by which change is triggered or effectuated, which would include mechanical cases like the classic bumping billiard balls — are not what is most fundamental in making things the way they are. By contrast, the Latin medievals made the efficient cause the root of all others, also applying it to God’s activity of creation from nothing.

Common early modern notions of causality started from this medieval reversal of Aristotle, assuming that efficient causes of the billiard-ball variety came first in the order of explanation. This was related to a widespread anti-Aristotelian privileging of immediacy. Kant and Hegel later developed strong critiques of the privileging of immediacy, but this aspect of their thought was not adequately understood and highlighted until recently. A reduction of all causes to allegedly immediate causes is an error common to both voluntarism and determinism.

Descartes developed a bottom-up explanatory model, starting from simple mechanical causes. This was good for science at a certain stage of development, but bad for philosophy. I would not wish to say that bottom-up explanations have no use (in delimited contexts, they most certainly do). I mean only that it is a delusion to think that nothing else is required, or that they can provide an absolute starting point.

In ethics, Aristotle’s notion of character is a nice relief from the seesaw of free will and determinism. Character is an acquired disposition to act in certain ways. The character of an individual resembles the culture of a community, and the same word (ethos) is used for both. We acquire it gradually over time, from an accumulation of our actions and things that have happened to us. Due to the contributing role of our actions in successive layers of character formation, we are in a broad way accountable for our disposition. On the other hand, it makes little sense to blame someone for acting in accordance with their disposition.
