Abstract

In Without Justification,[1] Jonathan Sutton undermines the orthodox view that a justified belief needn’t constitute knowledge; develops a battery of arguments for the unorthodox thesis that you justifiedly believe P iff you know P; and explores the topics of testimony and inference in light of his equation of justification and knowledge (J=K). This book is essential reading at epistemology’s cutting edge. In §I, we’ll take an extended tour of the book, raising various questions and objections along the way. In §II, we’ll assess Sutton’s three main arguments for J=K, which form the heart of his project.
