Aristotelian Causes

I’ve explained each of the four classic Aristotelian “causes” as playing what Brandom would call an expressive role, helping to explain other meaning, and pointed out how different this is from standard modern notions of what I’ve been calling univocal causality. An Aristotelian cause (aitia) is much more like a nonexclusive reason than it is like anything expressed by mechanical metaphors.

There is another very important modern way of thinking about these matters, inspired by Hume’s critique of realism about causes in the modern sense. Hume pointed out that modern-style talk about cause and effect involves a kind of inferential extrapolation from observed regular patterns of succession. Implicitly influenced by this, much work in the sciences relies directly on statistical correlations observed in data from controlled experiments. What particular causes are said to be at work then becomes a matter of optional statistical inference, subject to possible debate.

Then, too, from the side of subject matter, in fields concerned with complex dynamical systems that can only be modeled in a very tentative way — like ecology, economics, and medicine — it has come to be widely recognized that many causes combine to produce the results we see.

Both the statistical approach and what I’m gesturing at as a “complex systems” approach to causality avoid reliance on mechanical metaphors. Neither of these perspectives rules out underdetermination or overdetermination, or the simultaneous presence of both.

Aristotelian “causality” is simultaneously underdetermining and overdetermining. That is to say, in advance it leaves room for varying outcomes, but in hindsight it provides multiple rationales for a given outcome. Its purpose is to provide not certain prediction, but intelligibility and reasonableness.

In principle, nothing would stop us from combining this with statistical or complex-systems views, but these are still very different approaches. The statistical approach is quantitative and relies on counting minimally interpreted facts, where the Aristotelian approach is qualitative and puts the whole emphasis on rational interpretation. The complex-systems view relativizes causes in the modern event-based sense, without making them like any of the Aristotelian ones, none of which corresponds to an event. It is also not interpretive in the sense developed here.

One might consider mathematical-physical law as a kind of formal cause. Statistics and things like dynamic models could be taken as modern, quantitatively oriented descriptions of what I have called material tendencies. (See also Secondary Causes; Form; Aristotelian Matter; Efficient Cause; Ends; Natural Ends; Aristotelian Identity; Aristotelian Demonstration.)

Natural Ends

Early modern science sought to banish consideration of ends from the empirical world, in favor of purely mathematical and factual description. Kant recovered a heuristic use of teleology, especially in biology (see Kant’s Recovery of Ends), and numerous more recent biological researchers have followed suit.

It is relatively easy to see that any kind of desire (say on the part of an animal) is a desire for something that is usually more general than a concrete object that satisfies the desire. More broadly, living things can also plausibly be said to have indwelling tendencies of nutrition and reproduction.

The case of inorganic nature is a bit more challenging for us to understand this way, but where modern science sees abstract mathematical-physical laws in operation, the effect of which may be modified by various circumstances, Aristotle saw concrete material tendencies for things to develop in certain ways, subject to similar modifications. At a certain level of abstraction, observable material tendencies can be viewed as “moving” things in a way broadly analogous to desire. The heavy object “wants” to fall. This just refers back to the observed fact that heavy objects have a tendency to fall, when not impeded by something else. At a level of common-sense interpretation of experience, this does not lead to any false conclusions.

There is no reason why the mathematical-law description and the material-tendency description cannot coexist. The predictive power of mathematically formulated laws makes them invaluable for engineering applications. But for ordinary life, what we are usually interested in are qualitative distinctions that have practical significance.

Thus, in addition to rational ends, there seem to be three kinds or degrees of natural ends or endlike things: ends of desire; primitive vital ends; and endlike tendencies associated with Aristotelian matter of various kinds and descriptions. (See also Ends; Aristotelian Matter.)

Aristotelian Equality

Aristotle explains justice as a kind of proportionality, or equality of relations between people and similar objects of concern. The pseudo-Aristotelian treatise Magna Moralia virtually identifies justice with equality between people, but then disappointingly goes on to say that since, e.g., there is no equality between father and son or master and servant, the concept of a justice between them does not apply. Aristotle himself was careful to point out that empirically existing distinctions between people in the positions of masters and servants do not necessarily reflect inherent ones between people, and this ought to be generalized. Surviving texts do not explicitly put the same caveat on, e.g., existing inequalities between the sexes, but it seems to me the same logic should apply.

It also seems to me that equality of relations between people and similar objects of concern actually implies effective equality between people. A generalized equality between people would have been a highly controversial assertion in Aristotle’s time, and it seems to me he should be commended for implying it, rather than criticized for failing to make it explicit. It is in this spirit that I consider the Kantian emphasis on ethical univerality a welcome addition, complementing rather than conflicting with Aristotle’s highly cultivated sensitivity to the nuances of particular situations.

Theory and Practice

Unlike Plato, Aristotle did not make theoretical knowledge an ethical criterion, although he played a great role in the development of many fields of inquiry. Nonetheless, he placed intellectual “virtue” alongside friendship or love as an essential component of the highest ethical development.

I previously suggested there is an indirect way in which any inquiry can help make us better deliberators. Knowledge can of course help, but only if it is relevant to the question at hand. But the ethical value of inquiry lies more in a kind of theoretical practice than in the particular knowledge that may result. Intellectual virtue, I want to say, has to do especially with practices of free and well-rounded interpretation.

Aristotelian Virtue

Aristotelian ethics is not just about cultivating virtue as a kind of good character. Although he does emphasize it a lot, ultimately character is just a means and a potentiality for actualization of the real goal of that part of living well that is under our power. The actualization itself comes from good practice (praxis), grounded in sound, well-rounded deliberation and choice. Aristotle also says the very best life is that of the philosopher. Not only is philosophy valuable in itself, but it also helps us deliberate.

The best deliberation and choice is supported by intellectual virtues, a concern for justice, and a spirit of friendship or love, but it would not even get off the ground without progress in the classic “moral” virtues, which are all said to pertain to our emotions or passions, and to how we are affected by pleasure and pain. Aristotle characterizes each of these emotional virtues as a kind of mean, or balanced emotional state.

Thus, courage is presented as a mean between rashness and cowardice. Temperance is a mean between self-indulgence and insensibility. Interestingly, justice and prudence are also included among emotional virtues, and subjected to a similar analysis. Other emotional virtues are presented as following the same pattern. Unlike the Stoics, neither Plato nor Aristotle advocated suppressing the emotions.

Auspicious Grafts

Ideas of different philosophers — or interpretations of them — cannot just be arbitrarily combined, but they may turn out to be compatible if there is some common basis, or if they have a different scope of application. My semantic Aristotle has a substantial common basis with Brandom’s Kant and Hegel, which is not too surprising, since my reading of Aristotle has among other things benefited from thinking about Brandom’s work, and at a deeper historical level, independent of Brandom, there is a common basis in guiding notions of reason and rational ethics.

I’ve recently commented on connections between Aristotelian and Hegelian dialectic, and previously on Aristotle’s partial anticipation (in his discussion of friendship) of Hegel’s key notion of mutual recognition. It also seems to me that in a very broad way, something like the idea of Kantian synthesis was implicit in Aristotle, so a fuller account can be treated as a welcome addition. Related to this, Kant’s notion of unity of apperception — particularly with Brandom’s way of reading it as an ethical goal — sounds very good from an Aristotelian point of view concerned with ends. (See also Aristotle and Kant; Hegelian Genealogy; Retrospective Interpretation.)

Retrospective Interpretation

In studying the past, we should first do all we can to understand it in its own terms, and only then consider possibly anachronistically applying concepts from a later time. But sometimes, such retrospective application can yield real insight. For instance, some time ago I realized that the logical meaning of Aristotle’s two proposition-forming operations of “combination” and “separation” of terms is actually very well explicated by Brandom’s notions of material consequence and material incompatibility (see Aristotelian Propositions).

Philosophers sometimes develop their own very distinctive meanings for common terms, in which case interpreting those terms in the common way can result in serious misunderstanding, and naturally this can also affect the validity of applying them retrospectively. So, for instance, under a “common” interpretation, Hegel’s talk about the concerns of Socrates for Self-Consciousness and Freedom makes little sense. But with a better understanding of Hegel’s distinctive use of these terms, it is much more intelligible. (See also Hegelian Genealogy.)

Summing Up So Far

A philosophical approach to ethics brings in many considerations that may initially seem remote from the question of what to do, but can greatly enrich our ability to think about it.

Philosophy is not just any view of the world, but an inquiry into the meaning of things that is sustained and free. It also could not be the activity of an isolated individual. It is an intrinsically historical development, because it is a cumulative achievement of the virtual universal community of talking animals across space and time, through various ups and downs. The best way into it is through a kind of dialogue with the great philosophers. Pursuing this in depth turns out to involve many historiographical questions.

Truth does not come to us ready-made. What we take as truth is always the provisional result of a development. The primary activity of reason is the determination of meaning through a kind of open-ended interpretation. It is therefore involved with a kind of hermeneutics.

Ethics involves us as whole beings. Subjectivity is manifold. Its ethically important aspects have to do both with our acquired emotional constitution and with shareable contents and commitments.

Plato vs Aristotle?

Plato and Aristotle agreed on some matters, and disagreed on others. Throughout the modern period, authors have frequently resorted to rather stereotyped contrasts between them. In the ancient world, the neoplatonists made a serious effort to read Aristotle in terms of their own traditionally “metaphysical” reading of Plato, and thus to largely reconcile the two (see Fortunes of Aristotle; Plotinus). This resulted in a lot of distortion of Aristotle — some of which has persisted to this day — alongside a lot of original development that is only very recently again being appreciated and studied.

I’m putting forward a largely reconciling view, but going in the opposite direction from that of the neoplatonists. That is to say, while the works of Plato will always remain literary classics, I think Aristotle captured the best of Plato philosophically, while adding tremendously valuable further development. Where Aristotle criticized Plato or others in the Academy, the criticisms generally seem sound to me. I also think what are considered late works of Plato like Theaetetus, The Sophist, and even Parmenides may show development in a more Aristotelian direction, especially with regard to the theory of form.

Platonic Truth

Plato was much more concerned with what might be called truths of essence than with truths of fact. Truths of essence involve interpretation of meaning, and always have an implicit normative dimension. They are inseparably involved with questions of what is good or right. As Aristotle might say, they tell us what and why something is rather than merely “that” something is.

There is no general way to test whether we have completely grasped an essence, and not just what Hegel would call a one-sided view of it. As Brandom might say, all grasping of essences is defeasible. Plato makes his leading characters say many things that apply this in particular cases. Essences are the object of interpretation, not certain knowledge.
