Kantian Maxims

Kantian maxims are a kind of subjective rules providing rationale or justification for concrete ethical choices. A proper Kantian maxim should be a function from a list of conditions and a motive or aim to a uniquely determined conclusion that a particular concrete choice is or is not permissible for a moral being. It does not tell us exactly what to do, but it is expected to definitively tell us whether something is okay or not okay. It is a kind of inference rule.

Many maxims will fail to be universalizable. Kant says we should only trust the ones that can pass testing by the categorical imperative.

Where Aristotle had stressed an open-ended rational inquiry and the irreducibility of ethics to an exact science, Kant recommended focusing deliberation more narrowly on a search for deterministic functions satisfying the categorical imperative that will tell us if possible actions are okay or not.

Another important difference is that Kantian deliberation stops at what is permissible, whereas Aristotelian deliberation extends all the way to what to do, so the Aristotelian kind has a strictly broader scope.

The question is whether by thus narrowing the scope of ethical inquiry in conjunction with his other moves, Kant really succeeded in making the narrowed scope fully deterministic.

Kant talked much more about testing maxims than about searching for them or formulating them. If we were searching, presumably we would try to match on the conditions and aim that would be the inputs to the function. There might be questions about the granularity with which the conditions and aim are specified. To adequately address the complexities of real life, we would need a huge array of possible functions.

It is hard to even imagine a procedure for initially formulating the function-body of a maxim that would tell us specifically how to get from the inputs to a deterministic output. All we have is tests whether an already formulated candidate maxim is universalizable or not. Actual formulation of maxims thus seems to be left to trial and error. Kant might say the important thing is the ability to test, but it seems to me that if we cannot deterministically say how maxims are to be formulated, we cannot really claim to have a deterministic solution to the whole problem of ethical decision-making.

It seems as though Kant was successful in establishing that valid ethical conclusions do have necessary conditions that no one before him recognized, but unsuccessful in defining conditions that would be both necessary and sufficient to derive those conclusions, even at the level of just considering what is permissible. Thus, we still need Aristotelian open-ended deliberation and practical judgment, or an ethical analogue of Kant’s own notion of free play in aesthetics. I also still like the Leibnizian principle of wise charity — within reason, doing more and demanding less than what is nominally required of us.

Kantian Obligation

Kantian ethics is explicitly governed by a spirit of universality. Universality is the one principle that drives everything else. Arguably, a concern for universality has been implicit in rational ethics since Plato and Aristotle, but Kant made it explicit and absolutely central; formulated it in a more rigorous way; and suggested several informal tests for it (the different formulations of the categorical imperative) that could be used in deliberation. Because it is possible to test maxims for compliance with the categorical imperative, Kant’s one principle can actually serve as a criterion, unlike Plato’s undefinable Good.

Universality implies no exceptions, so it can underwrite a kind of unconditional moral necessity that had no precedent in rational ethics before Kant. It seems that Kant wanted to contest Aristotle’s conclusion that ethics can never be an exact science. Kant borrowed talk about duty from what Brandom has called the traditional one-sided authority-obedience model of morality, but gave it new, rational, universal content. For Kant, every ethical decision should be approached as an instance and application of universal law. This means that in deliberation, we are not just deciding for ourselves what is right here and now, but what would be right for any rational being in similar circumstances. Kant wants us to act as universal legislators, and to respect the principle of humanity in every person.

There is something compelling about this, even for a convinced Aristotelian such as myself. Kant really did come up with something new. But also, Aristotelian sensitivity to particulars has been to an extent historically abused and hijacked by people with “particularist” agendas that Aristotle did not countenance, so a nudge in the direction of universality and respect for all humans is a welcome corrective.

This is not the end of the story. As I’ve noted numerous times, the absolute necessity of the categorical imperative applies only at an extremely abstract level, quite some distance from real-world application. I think this is at the core of Hegel’s impatience with Kantian “formalism”. Hegel is not quite fair to Kant, but Kant often seemed to want to claim he had reduced the whole of ethics to necessity, while directing our attention away from the parts he actually left open.

Next, I need to take a closer look at Kantian maxims, which are supposed to provide the bridge to real life. (See also Categorical Imperative; Kant’s Groundwork; Necessity in Normativity; Deontic; Binding.)

Freedom Through Deliberation?

All sincere deliberation cumulatively contributes to opening our minds.

Kant did not discuss Aristotle directly, but he clearly wanted to assert a stronger notion of freedom than emerges just from Aristotle’s distinction of willing from unwilling actions. This relative kind of voluntariness was not enough to ground the kind of freedom Kant was after. For Kant, as long as we are under the sway of our own internal impulses, we are not free, so a lack of external compulsion is not sufficient. But that is not the end of the matter.

“Will” for Kant turned out to be a rational, positively developed alternative to impulse, grounded in a concept (i.e., thoughtful interpretation) of law. Aristotle’s version of thoughtful interpretation in this context is deliberation. It makes sense that active deliberation would positively, incrementally contribute to deautomatizing our tendency to act or respond impulsively. So, I think the closest analogue for what Kant would call true freedom in Aristotle is action on the basis of deliberation. Everything Aristotle says about what is in effect acquired emotional intelligence is also relevant to these Kantian considerations. (See also Beauty, Deautomatization.)

Ethical Skill?

In mentioning “ethical skills”, I by no means want to imply that ethics overall could be reduced to something like a technical skill. People can have all sorts of skills and still be profoundly unethical. However, specific kinds of attentiveness and deautomation of impulse do become easier with practice. Aristotle also talks about people who are skilled in deliberation. (See also Beauty, Deautomatization; Freedom Through Deliberation?)

Choice, Deliberation

Aristotle’s Nicomachean Ethics book 3 chapter 2 concerns choice. Choice is something willing, but not everything done willingly is done by choice. Things spontaneously done by children and animals and things done on the spur of the moment are done willingly and so are subject to praise or blame, but they are not done by choice.

Choice is not desire or spiritedness or wishing or opinion. It is involved with reason and thinking things through. It is the outcome of deliberation, the subject of chapter 3. It is the deliberate desire of things that are up to us (Sachs translation, p.43). It comes from desire combined with a rational understanding that is for the sake of something (p.103); it is “either intellect fused with desire, or desire fused with thinking, and such a source is a human being” (p.104). (The phrase “fused with” is actually an interpolation by the translator — the Greek actually just has “intellect and desire”, without specifying how they are related.)

We deliberate about things that are up to us and are matters of action. Deliberation is neither knowledge nor opinion. Inquiry about exact sciences or general truths or ends is not deliberation, but deliberation is a kind of inquiry. Deliberation applies to means for achieving ends, when outcomes can be predicted with some confidence, but are still uncertain. On big issues, we consult others. When there is more than one means to an end, deliberation seeks the one that is easier and more beautiful.

Deliberation may also examine how a thing will come about through a particular means, what other means are required for that means, and so on. Aristotle says that the analysis of dependencies of means and ends in particular works just like a mathematician’s analysis of a geometrical diagram.

Deliberating well overall belongs to people with good practical judgment (p.112). “What is deliberated and what is chosen are the same thing, except that the thing chosen is already determined, since the thing chosen is what is decided out of the deliberation.” (p.43.) Aristotelian choice is therefore anything but arbitrary. It is a normative and rational determination, emerging from an open, fallible, and pluralistic process. (See also Brandomian Choice.)
