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.

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

It seems to be an obvious truth that There could be something that doesn't actually exist.That is, it seems to be obiously true that ◊∃×).It is sufficient for the truth of that there could be more people, or trees, or cars, than there actually are. It is also sufficient for the truth of that there could be some pepole, or trees, or cars that are distinct from all those that actually exist. Do and suchlike statements involve a commitment to possibilia, to things that possibly exist, but do not actually exist? If not, why not? And if so, what is the nature of the possibilia to which and its ilk commit us? These simple little questions are at the tip of an iceberg.

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.

This paper presents an account of the understanding of statements involving metaphysical modality, together with dovetailing theories of their truth conditions and epistemology. The account makes modal truth an objective matter, whilst avoiding both Lewisian modal realism and mind-dependent or expressivist treatments of the truth conditions of modal sentences. The theory proceeds by formulating constraints a world-description must meet if it is to represent a genuine possibility. Modal truth is fixed by the totality of the constraints. To understand modal discourse is to have tacit knowledge of the body of information stated in these constraints. Modal knowledge is attained by evaluating modal statements in accordance with the constraints. The question of the general relations between modal truth and knowability is also addressed. The paper includes a discussion of which modal logic is supported by the presented theory of truth conditions for modal statements.

The topic of Being Known is what I call the Integration Challenge, which is the challenge of providing, for any given domain, a simultaneously acceptable metaphysics and epistemology for that domain. In virtually every domain of thought, it is a substantive task to reconcile our metaphysics and our epistemology of that domain. In some cases, we have an intuitively acceptable metaphysics, but cannot find a plausible epistemology which would allow us knowledge of truths for which that is the right metaphysics. In others, the reverse situation obtains. In yet others, we have an intuitive metaphysics and an intuitive epistemology, but cannot see how they are to be reconciled.
