What is the Darwinian revolution and why is it important for philosophers? These are the questions tackled in this Element. In four sections, the topics covered are the story of the revolution, the question of whether it really was a revolution, the nature of the revolution, and the implications for philosophy, both epistemology and ethics. ‘The refreshing aspect of this rambling romp through the history and philosophy of the Darwinian revolution is that although Ruse is writing for young philosophers of science, he does so from a place of comfort both with the science and the history. In doing so, he provides the perfect introduction to this diffuse and contentious literature, which can be rather foreign terrain for uninitiated biologists.’ John Reiss, The Quarterly Review of Biology Covers the Darwinian revolution, whether it really was a revolution, its nature, and the implications for epistemology and ethics.
