Abstract

Drawing upon neuroscientific research, Schroeder argues that there is biological evidence in favor of his philosophical conclusions. Specifically, the brain areas that show activity correlated with feelings of pleasure are distinguishable from those that seem to be associated with the consciousness of possible reward; and, in theory, these latter areas “could exist” in an organic being that lacked the capacity for behavior. At this point, the partly theoretical basis of Schroeder’s scientific claims might worry a reader who has doubts about the whole program of neurophilosophy: after all, to what degree can empirical findings help us to understand a complex mental phenomenon such as desire? This question, which begs to be asked, is given an oblique answer in Three Faces of Desire when the reader is assured that what Schroeder is advocating is neither an identity theory, in which desire would be equated with certain neuronal events, nor a reductive project which aims to replace philosophical discussion of desire and other mental phenomena with the language of quantitative measurement. Like many other contemporary philosophers of mind, Schroeder accepts that mental functions are “multiply realizable” : that is, no matter how a process may be realized in the embodied human mind, it still could be instantiated differently, in another kind of living organism.
