Evidence and epistemic evaluation

This chapter examines a problematic consequence of the popular probability-raising conception of evidential support, namely that any proposition which is evidence for some hypothesis is evidence for itself. It examines whether the defender of the probability-raising account can avoid this consequence by modifying either of the two conditions they place on a proposition p being evidence for a subject for a hypothesis h: that 1) p is part of the subject’s evidence; and, 2) p raises the probability of h. The chapter defends an invariantist modification of the second condition which appeals to the notion of warrant transmission.
