Abstract

Issues of identity and reduction have monopolized much of the philosopher of mind’s time over the past several decades. Interestingly, while investigations of these topics have proceeded at a steady rate, the motivations for doing so have shifted. When the early identity theorists, e.g. U. T. Place ( 1956 ), Herbert Feigl ( 1958 ), and J. J. C. Smart ( 1959 , 1961 ), fi rst gave voice to the idea that mental events might be identical to brain processes, they had as their intended foil the view that minds are immaterial substances. But very few philosophers of mind today take this proposal seriously. Why, then, the continued interest in identity and reduction? Th e concern, as philosophers like Hilary Putnam and Jerry Fodor have expressed it, is that a victory for identity or reduction is a defeat for psychology. For if minds are physical, or if mental events are physical events, then psychologists might as well disassemble their laboratories, making room for the neuroscientists and molecular biologists who are in a better position to explain those phenomena once misdescribed as “psychological.” Th e worry nowadays is not that locating thought in immaterial souls will make psychology intractable, but that locating thoughts in material brains will make it otiose.
