Abstract
Conventional wisdom has long maintained that Descartes considered animals to be unfeeling machines with no capacity for perceptual states like pain, and that Descartes's mechanistic view of animals was the basis for his claim that we owe animals no moral obligations. Several recent commentators have sought to repudiate this conventional wisdom, either by denying that Descartes had a purely mechanistic conception of animal perception or by attempting to argue that Descartes allowed for the possibility that animals have souls. An examination of Descartes's writings in the light of his Greek and Christian philosophical precursors shows that he did indeed consider animals to be pure mechanisms without immortal souls; it was not this belief, however, but rather the Stoic principle of community that was the basis of his views on the moral status of animals
