The motivation for this volume is simple. For a variety of reasons,
clinical psychologists have long shown considerable interest in the
philosophy of science. When logical positivism gained currency in the
1930s, psychologists were among the most avid readers of what these
philosophers had to say about science. Part of the critique of Skinner's
radical behaviorism and thus behavior therapy was that it relied on, and
thus was logically dependent on, the truth of logical positivism-a claim
decisively refuted both historically and logically by L.D. Smith (1986)
in his important Behaviorism and Logical Positivism: A Reassessment of
the Alliance.
