Abstract
Introduces several of the concepts and assumptions that will occupy center stage in the book's main argument. In particular, introduces the notion of a research programme, and provides characterizations of realism about material objects and its rival, constructivism. Also defends the conclusion that it is impossible to adopt a research programme on the basis of evidence. This constitutes the author's argument for the conditional claim that if naturalism is a research programme, its status as orthodoxy is without rational foundation. Introduces the central thesis of the book – that naturalists are committed to rejecting realism about material objects, materialism, and perhaps realism about other minds – and goes on to provide a brief outline of the remaining chapters.
