Book excerpt: The concepts of form and function have traditionally been defined in terms of biology and then extended to other disciplines. Stephen T. Asma examines the various interpretations of form and function in science and philosophy, reflecting on the philosophical presuppositions underlying the work of Geoffroy, Cuvier, Darwin, and others. In the continental tradition of Canguilhem and Foucault, Asma's treatment of the historical form/function dispute analyzes the complex interactions among ideologies, metaphysical commitments, and research programs. Following Form and Function is a significant contribution to the history of science, history of philosophy, and disputes within contemporary biology.
