Abstract

A number of philosophers have recently defended “contrastivist” theories of knowledge, according to which knowledge is a relation between at least the following three relata: a knower, a proposition, and a contrast set. I examine six arguments that Jonathan Schaffer has given for this thesis, and show that those arguments do not favour contrastivism over a rival view that I call “evidentiary relativism”. I then argue that evidentiary relativism accounts for more data than does contrastivism
