Consider the skeptic about the external world. Let’s straightaway concede to such a skeptic that perception gives us no conclusive or certain knowledge about our surroundings. Our perceptual justification for beliefs about our surroundings is always defeasible—there are always possible improvements in our epistemic state which would no longer support those beliefs. Let’s also concede to the skeptic that it’s metaphysically possible for us to have all the experiences we’re now having while all those experiences are false. Some philosophers dispute (...) this, but I do not. The skeptic I want to consider goes beyond these familiar points to the much more radical conclusion that our perceptual experiences can’t give us any knowledge or even justification for believing that our surroundings are one way rather than another.

On the face of it, some of our knowledge is of moral facts (for example, that this promise should not be broken in these circumstances), and some of it is of non-moral facts (for example, that the kettle has just boiled). But, some argue, there is reason to believe that we do not, after all, know any moral facts. For example, according to J. L. Mackie, if we had moral knowledge (‘‘if we were aware of [objective values]’’), ‘‘it would have (...) to be by some special faculty of moral perception or intuition, utterly different from our ordinary ways of knowing everything else’’(1977,p.38).But wehavenosuchspecialfaculty.So,wehavenomoralknowledge. Following Mackie, let us distinguish two questions: Q1: Assuming that we have moral knowledge, how do we have it? Q2: Do we in fact have any moral knowledge? In response to the first question, I argue that if we have moral knowledge, we have some of it in the same way we have knowledge of our immediate environment: by perception. Many people think that this answer leads to moral skepticism, because they think that we obviously cannot have moral knowledge by perception. But I will argue that this is incorrect. The plan for the paper is as follows. In Sections 2–4, I work up to my answer to Q1 by considering rivals. In Section 5, I explain what marks my answer to Q1 as a distinctive view, and defend it. In Section 6, I briefly discuss how this answer to Q1 affects what we say in response to Q2. (shrink)

This essay distinguishes between metaphysical and epistemological conceptions of analyticity. The former is the idea of a sentence that is ‘true purely in virtue of its meaning’ while the latter is the idea of a sentence that ‘can be justifiably believed merely on the basis of understanding its meaning’. It further argues that, while Quine may have been right to reject the metaphysical notion, the epistemological notion can be defended from his critique and put to work explaining a priori justification. (...) Along the way, a number of further distinctions relevant to the theory of analyticity and the theory of apriority are made and their significance is explained. (shrink)

A while ago I pulled the short straw, and became chair of my department. One nice part of the job is to praise people I work with, which I can do sincerely because they are very praiseworthy. I also have to read a lot of praise by others; the familiar things—project evaluations, letters of recommendation, promotion dossiers, and so on and so forth. As a result, I have learnt to attend to praise a little more closely.

My goal in this paper is to explain what ethical naturalism is, to locate the pivotal issue between naturalists and non-naturalists, and to motivate taking naturalism seriously. I do not aim to establish the truth of naturalism nor to answer the various familiar objections to it. But I do aim to motivate naturalism sufficiently that the attempt to deal with the objections will seem worthwhile. I propose that naturalism is best understood as the view that the moral properties are natural (...) in the sense that they are empirical. I pursue certain issues in the understanding of the empirical. The crux of the matter is whether any synthetic proposition about the instantiation of a moral property is strongly a priori in that it does not admit of empirical evidence against it. I propose an argument from epistemic defeaters that, I believe, undermines the plausibility of a priorism in ethics and supports the plausibility of naturalism. (shrink)
