In this essay, I propose a novel way of thinking about Kant’s philosophical methodology during the critical period. According to this interpretation, the critical Kant can generally be understood as operating within a “capacities‐first” philosophical framework – that is, within a framework in which our basic rational or cognitive capacities play both an explanatorily and epistemically fundamental role in philosophy – or, at least, in the sort of philosophy that limited creatures like us are capable of. In discussing this idea, (...) I consider the complicated relationship between the explanatory and epistemic roles that such capacities play in Kant. I also sketch how this way of thinking about Kant’s methodology can illuminate the foundations of both his theoretical and his practical philosophy, before discussing some of Kant’s reasons for finding this approach to philosophy attractive. I close with a brief discussion of the contemporary relevance of this approach. (shrink)

A measure of good and bad is internal to something falling under it when that thing falls under the measure in virtue of what it is. The concept of an internal standard has broad application. Compare the external breed standards arbitrarily imposed at a dog show with the internal standards of health at work in the veterinarian's office. This paper is about practical standards, measures of acting well and badly, and so measures deployed in deliberation and choice. More specifically, it (...) is about the attempt to explain the unconditional validity of certain norms (say, of justice and prudence) by showing them to be internal to our agency and the causality it involves. This is constitutivism. Its most prominent incarnations share a set of assumptions about the nature of agency and our knowledge of it: conceptualism, formalism and absolutism. This essay investigates the merits and viability of rejecting all of them while still seeking the ground of practical normativity in what we are, in our fundamental activity. (shrink)

Why should we be interested in Kant's ethical theory? One reason is that we find his views about our moral responsibilities appealing. Anyone who thinks that we should treat other people with respect, that we should not use them as a mere means in ways to which they could not possibly consent, will be attracted by a Kantian style of ethical theory. But according to recent supporters of Kant, the most distinctive and important feature of his ethical theory is not (...) his claims about the particular ethical duties that we owe to each other, but his views about the nature of value. They argue that Kant has an account of the relationship between practical reason and value, known as "Kantian constructivism" that is far superior to the traditional "value realist" theory, and that it is because of this that we should accept his theory.1 It is now standard for both supporters and critics to claim that Kant's moral theory stands or falls with Kantian constructivism.2 But this is a mistake. In this paper, I sketch a rival Kantian theory of value, which I call Kantian value realism. I argue that there is textual evidence that Kant himself accepted value realism rather than constructivism. Whilst my aim in this paper is to set out the theory clearly rather than to defend it, I will try to show that Kantian value realism is preferable to Kantian constructivism and that it is worthy of further study.

Practical cognitivism is the view that practical reason is the self-conscious will and that practical cognition is self-conscious volition. This essay addresses two puzzles for practical cognitivism. In akratic action, I act as I understand is illegitimate and not as I understand is legitimate. In permissible action, I act as I understand is legitimate and also do not act as I understand is legitimate. In both types of action, practical cognition seems to come apart from volition. How, then, can practical (...) reason be our will and practical cognition be volition? Practical cognitivists can solve these puzzles because the claims that practical reason is our will and that practical cognition is volition are about the nature of a capacity, and the nature of a capacity establishes standards of correctness for its exercises. Akratic action is a type of erroneous exercise of practical reason as tripping is an erroneous exercise our capacity to walk. Permissible action is a successful exercise of practical reason as stepping first with my right foot rather than my left is a successful exercise of my capacity to walk. The puzzles of akratic and permissible action do not refute practical cognitivism. (shrink)

The possibility of error conditions the possibility of normative principles. I argue that extant interpretations of this condition undermine the possibility of normative principles for our action because they implicitly treat error as a perfection of an action. I then explain how a constitutivist metaphysics of capacities explains why error is an imperfection of an action. Finally, I describe and defend the interpretation of the error condition which follows.

Properly understood, the instrumental rule says to take means that actually suffice for my end, not, as is nearly universally assumed, to intend means that I believe are necessary for my end. This alternative explains everything the standard interpretation can—and more, including grounding certain correctness conditions for exercises of our will unexplained by the standard interpretation.
