This paper argues for a shift in the debate surrounding McDowell’s conceptual-ism: from contents to capacities. This shift is important because the conceptual nature of a capacity is revealed in the way the capacity figures in the life of the animal, in particular in how the animal acquires and sustains the capacity. More specifically, I argue that a capacity is conceptual insofar as the subject can improve it by systematically exploiting interconnections among the features involved in its exercise. I first develop this notion through an analysis of skillful action, showing how a skilled agent perceives the interlocking demands of a situation and uses this perception to refine her performance. I then extend the model to perception itself, arguing that perceptual learning exhibits the same structure: theoretical knowledge can reshape perceptual organization, bringing it under conceptual control. This yields what I call a systematically rational capacity, which, I argue, comes in degrees and is not specific to humans. I next examine McDowell’s account of virtue, where practical wisdom is shown to consist in an intimate harmony between intellect and sensibility rather than a computation between independent components. I argue that this harmony, far from being restricted to the ethical domain, characterizes the relation between reason and sensibility in general:our intelligence just is the properly molded state of our perceptual capacities, reflectively adjusted. Finally, I turn to the role of language, which enables a degree of systematic integration unavailable to non-linguistic animals, and argue that language’s deepest contribution is not merely representational but ethical, and that here we can find what is special about us:language initiates us into a shared form of life in which we matter to one another and have a say in shaping what matters.

In this article, I examine Davidson’s surprising argument, in his John Locke Lectures, that speaking the truth is what he calls an essentially disengaged act. I show he defends in these lectures a type of semantic conventionalism, and how he took this conventionalism to entail the essentially disengaged character of speaking the truth. I then show how his characterization of the Principle of Charity, in those lectures themselves, suggests a powerful argument against the essentially disengaged character of speaking the truth, and, thus, against semantic conventionalism. Finally, I examine how he could have failed to notice this in the lectures by examining his changing picture of communication and the role the Principle of Charity plays in such exchanges.

In this article, I will offer some remarks about Tarski’s nominalism. First, I will show that, even though it was mainly developed in private conversation and lectures, Tarski did try to develop a rigorous nominalistic theory, which shows that the issue was of some importance to him. In particular, I show how Tarski’s formulation is based on the idea of a humanly understandable language and show how he tried to develop this idea throughout his career. Unfortunately, even though his formulation is interesting, it seems to face an insurmountable obstacle, which I examine in detail in the article. Finally, I offer some remarks about what went wrong with Tarski’s nominalist program.
