Abstract
David Sanford's If P, Then Q is an ambitious book, aimed at two difficult tasks and addressed to two audiences. It combines a survey of historical and contemporary work on-conditionals with a presentation-of, Sanford's personal views. And it is addressed to both undergraduate students, without, logical training, and professionals seriously interested in conditionals. It is marred by the impossibility of achieving both aims in a book this size, and by the strains of simultaneously addressing audiences with such different needs and interests.
