How to Know

“In his latest book, How to Know, Stephen Hetherington forcefully challenges the orthodox conception of knowledge that has come to dominate nearly all contemporary discussions of knowledge. Hetherington's project is not merely critical, however. Instead he proposes a novel alternative theory of knowledge that he calls Practicalism, a theory that says that at root, all propositional knowledge (knowledge that) is ultimately reducible to practical knowledge (knowledge how).  …  Presuppositions and supposed platitudes in philosophy deserve to be challenged. Hetherington's highly original and insightful book does just that. Whether or not one accepts all aspects of Hetherington's alternative positive proposal, epistemologists will have much to gain from engaging with the details of his substantial contribution to the field.”  (Notre Dame Philosophical Reviews, 28 February 2012)
