Barry Allen, drawing on Wittgenstein's standard-metre example from Philosophical Investigations, argues there can be no determinate similarities or differences in the absence of a practice of measuring such similarities or differences. I contend that one can accept Allen's premises without accepting his conclusion if we draw a distinction between being and being true of the following sort: although it was not true, in the absence human or other epistemic practices, that water was H2O, nonetheless, before there were any human or other epistemic practices, water was H2O. This, I argue, is compatible with retaining the truism that it is true that p if and only if p, and it allows us to avoid the idealism of Allen's conclusion.

It is sometimes objected that anti-individualism, because of its assumption of the constitutive role of natural and social environments in the individuation of intentional attitudes, raises sceptical worries about first-person authority--that peculiar privilege each of us is thought to enjoy with respect to non-Socratic self-knowledge. Gary Ebbs believes that this sort of objection can be circumvented, if we give up metaphysical realism and scientific naturalism and adopt what he calls a “participant perspective” on our linguistic practices. Drawing on broadly Wittgensteinian considerations, I argue that Ebbs is right about this, and I show how two likely objections to his view can be circumvented. I also argue that mere adoption of the participant perspective does not serve to refute external-world sceptic.

In "What Truth Does the Emotive-Imperative Answer to the Open-Question Argument Leave to Moral Judgments?" David Braybrooke claims that the justification of a moral claim is independent of the justification of morality generally–that ethical justification does not have to be traced back to meta-ethical justification. I support this claim by appealing to a contextualist theory of epistemic justification. Drawing on the work of Michael Williams and Robert Brandom, I contend, first, that every claim is justified by default and requires articulated reasons only when it is challenged. Not every challenge is a reasonable challenge–only those that share the burden of proof are. Secondly, I hold that sceptics about moral truth and justification, such as J. L. Mackie, are committed to a substantive philosophical position, closely linked to foundationalism, that Williams has called “epistemological realism”, insofar as they hold that moral claims are intrinsically less certain than claims about non-moral facts on which moral facts might be taken to supervene. But there is no reason to believe that any propositions are intrinsically more certain than any others. Certainty is a function of epistemic context, not semantic or empirical content. Therefore, although moral claims may presuppose the truth of some meta-ethical claims, the justification of moral claims does not depend on the justification of meta-ethical claims.
