Abstract

This chapter provides an account of how a proposition E has to be related to a proposition H in order to make it possible for someone to know H inferentially on the basis of the evidence provided by E. It argues that the relationship between E and H that does the job is an objective, contingent probabilistic relation. More specifically, evidential support requires a high likelihood ratio and a high value for the probability of H given E. The resulting account of evidential support is very close to the theory of evidence presented in Sherrilyn Roush’s recent book.
