I just learned that Jason’s new book Knowledge and Interests will be out late summer or early fall with Oxford. Here’s the central claim of the book:
There are cases in which two people are similarly situated, but one has knowledge, whereas the other does not, because one has greater practical investment in the truth or falsity of her beliefs. The central purpose of this book is to argue that we must take our intuitions about these cases at face-value.
Some of the ideas in the book are on this blog and have appeared in previous papers of Jason’s, but I’m sure that leaves plenty of justification for buying the book!
