In his (1988), Brian Baigrie criticizes my earlier discussion of the rationality of science (Siegel 1985). In this response, I argue that (1) Baigrie misses the point of my tripartite distinction between different questions one can ask about science's rationality, (2) Baigrie's argument that the history of the development of methodological principles is crucial to philosophical discussion of the rationality of science is flawed, and (3) Baigrie's charge that my view is “anemic” rests on a failure to appreciate the point of my tripartite distinction.
