Durbin, history and philosophy of science scholar and writer, has created a volume that includes about 100 terms from the natural and social sciences. For each term there is an extended definition and discussion of related philosophic issues. Each entry, about three and one-half pages, also provides a bibliography of some six to a dozen sources. A thorough index includes all terms and people discussed in the entries. This is an excellent source for an entree to the scholarly literature on basic topics such as chance, gender, history, indeterminism, instrumentalism, paradigm, scientific method, and vitalism.
