Sextus Empiricus offers an underappreciated and under-discussed version of dream-based skepticism. Most philosophers interested in dreams and skepticism focus on the question of how you know you are not currently dreaming. Sextus points out that our waking experiences and dreams often conflict. And, the challenge goes, what reason do you have to trust the one over the other? This question presupposes that dreams and waking experiences are distinguishable. Thus the kinds of responses typically offered against dream-based skepticism do not apply. (...) And if we accept an idea upheld by one camp in the contemporary debate over the epistemology of disagreement, Sextus’ challenge is difficult to answer. A G.E. Moore-inspired response to the problem is also proposed and explored. It is argued that Sextus’ version of the problem reveals a certain limitation in that sort of approach to skeptical problems.

This paper proposes a methodological turn for the epistemology of disagreement, away from focusing on highly idealized cases of peer disagreement and towards an increased focus on disagreement simpliciter. We propose and develop a normative framework for evaluating all cases of disagreement as to whether something is the case independently of their composition—i.e., independently of whether they are between peers or not. The upshot will be a norm of disagreement on which what one should do when faced with a disagreeing (...) party is to improve the epistemic properties of one’s doxastic attitude or, alternatively, hold steadfast.

Norman forms the belief that the president is in New York by way of a clairvoyance faculty he doesn’t know he has. Many agree that his belief is unjustified but disagree about why it is unjustified. I argue that the lack of justification cannot be explained by a higher-level evidence requirement on justification, but it can be explained by a no-defeater requirement. I then explain how you can use cognitive faculties you don’t know you have. Lastly, I use lessons from (...) the foregoing to compare Norman’s belief, formed by clairvoyance, with Sally’s theistic belief, formed by a sensus divinitatis. (shrink)

To understand rational response to ethical disagreement, we need to consider how epistemic and ethical factors interact. The notion of an ethical peer is developed, and the roles that epistemic and ethical peers play in disagreement are compared. In the light of some literary examples, the view that conciliation in response to an ethical peer can be called for, even if that peer is an epistemic inferior, is defended.
