This paper is built around a single, simple idea. It is widely agreed that there is a distinctive kind of awareness each of us has of his own bodily actions. This action-awareness is different from any perceptual awareness a subject may have of his own actions; it can exist in the absence of such perceptual awareness. The single, simple idea around which this paper is built is that the distinctive awareness that subjects have of their own mental actions is a form of action-awareness. Subjects’ awareness of their own mental actions is a species of the same genus that also includes the distinctive awareness of bodily actions. More specifically, I claim

The classical problem of free will is one instance of the Integration Challenge. The Integration Challenge in its general form is that of reconciling our metaphysics of any given area with our epistemology for that same area. In the case of free will, the challenge is that of reconciling our seeming first-person knowledge of our exercise of free thought, deliberation, choice and action with a description of what is really going on in the world as characterized in terms of causation, determination, explanation and causal possibility

where F is a contradiction (I use his numbering). Tim says about these equivalences: (1) “modulo the implicit recognition of this equivalence, the epistemology of metaphysically modal thinking is a special case of the epistemology of counterfactual thinking. Whoever has what it takes to understand the counterfactual conditional and the elementary logical auxiliaries ~ and F has what it takes to understand possibility and necessity operators.” (158) (2) The idea that we evaluate metaphysically modal claims “by some quite different means [from those we use to evaluate counterfactuals – CP] is highly fanciful, since it indicates a bizarre lack of cognitive economy and has no plausible explanation of where the alternative cognitive resources might come from” (162) (3) “the capacity to handle metaphysical modality is an “accidental” byproduct of the cognitive mechanisms that provide our capacity to handle counterfactual conditionals” (162). The biconditional corresponding to a proposed definition of a concept C may be necessary and a priori. But that leaves open these questions: (1) Does the definition contribute to an explanation of why what are in fact truths containing C are true? (The Explanation Question) (2) Does the definition contribute to an explanation of our knowledge of certain contents containing C? (Epistemic Question) (3) Does the definition contribute to an explanation of our understanding or grasp of contents containing C? (Understanding Question) I argue that applied to (17) and (18), considered as definitions, the answers to these three..

There are issues in the theory of concepts about which A Study of Concepts could have said more. There are also some issues about which it would have done well to say something different. The commentators in this symposium have successfully identified a series of issues of one or other of these two kinds, and I am very grateful for their thought and detailed attention. I have learned from reflection on their comments, and I take this opportunity to try to carry the discussion forward by addressing a range issues underdeveloped in A Study of Concepts. Georges Rey raises global questions about the project of SoC. Answerability, Quinean challenges and the relations between my approach and covariation or ‘locking’ theories are amongst the problems he raises. The comments of David Papineau are at an intermediate level of generality. He poses questions about the subject-matter of a theory of concepts, and rejects my critique of teleological theories of content. He is also dissatisfied with my account of the relations between actual thought and the normative properties of concepts. I will consider that issue at some length. Jane Heal considers my elaboration of the approach for a specific concept, that of belief. I will take the topics in that order.

Representing one thing metaphorically-as something else is something that can occur in thought, imagination or perception. When a piece of music is heard as expressing some property F, some feature of the music is heard metaphorically-as F. The metaphor is exploited in the perception, rather than being represented. This account is developed and deployed to address some classical issues about music, including Wagner's point that the emotions expressed need not be those of a particular person on a particular occasion, and the widely accepted point that what is significant in a piece of music cannot be translated into any other medium.
