  The literature about reduction and molecular genetics has influenced philosophers' thinking about reduction in other sciences. For example, Kitcher's concept of reduction, which he uses to explain why molecular genetics cannot reduce classical genetics, has subsequently been employed by Hardcastle (1992) in her examination of the relationship between psychology and neuroscience. On the other side, Sober develops and extends the criticism of Kitcher's gory details objection (section 3.3) by re-examining the arguments of Putnam (1967, 1975) and Fodor (1968, 1975) on multiple-realizability.
