Abstract
This is an enormously ambitious book. The author not only develops a theory of empirical knowledge, but also develops a theory of reference, argues for both metaphysical and scientific realism, and deals with numerous subsidiary issues. He is extremely thorough in considering and critically discussing alternative views, and very careful and meticulous in the presentation and defense of his own. The book is also rich in interesting and occasionally ingenious ideas. It will make rewarding reading for anyone interested in these issues. It might also make an ideal starting point for someone who has been away from these fields for, say, a couple of decades, and wants to catch up on the state of the art.
