How should the contrastivist formulate closure? That is, given that knowledge is a ternary contrastive state Kspq (s knows that p rather than q), how does this state extend under entailment? In what follows, I will identify adequacy conditions for closure, criticize the extant invariantist and contextualist closure schemas, and provide a contrastive schema based on the idea of extending answers. I will conclude that only the contrastivist can adequately formulate closure.

In order for us to have epistemic justification, Sinnott-Armstrong believes we do not have to be able to rule out all sceptical hypotheses. He suggests that it is sufficient if we have 'modestly justified beliefs', i.e., if our evidence rules out all non-sceptical alternatives. I argue that modest justification is not sufficient for epistemic justification. Either modest justification is independent of our ability to rule out sceptical hypotheses, but is not a kind of epistemic justification, or else modest justification is (...) a kind of epistemic justification, but is not truly independent of our ability to rule out sceptical hypotheses.

This paper defends the view that standards, which are typically social in nature, play a role in determining whether a subject has knowledge. While the argument focuses on standards that pertain to reasoning, I also consider whether there are similar standards for memory and perception.Ultimately, I argue that the standards are context sensitive and, as such, we must view attributions of knowledge as indexical. I exploit similarities between this view and a version of the relevant alternatives reply to skepticism in (...) order to defend this reply against the objection that it is ad hoc. (shrink)

This précis summarizes my book Moral Skepticisms, with emphasis on my contrastivist analysis of justified moral belief and my Pyrrhonian moral scepticism based on meta-scepticism about relevance. This complex moral epistemology escapes a common paradox facing moral philosophers.
