What should one hope for from a philosophical study of practical thinking? Broadly speaking, one should hope for two things: first, an articulation of the similarities and differences between practical thinking and its more widely celebrated and carefully studied kin, comtemplative hinking; and second, an elaboration of what goes into practical thinking as well as of what practical thinking itself is a part. In Thinking and Doing Hector-Neri CastaŇeda presents a detailed and comprehensive theory of practical thinking, a presentation in which he carries out precisely this plan of study.
