AristotleÕs central argument for teleologyÑthough not necessarily his conclusionÑis repeated in the teleological arguments of Isaac Newton, Immanuel Kant, William Paley, and Charles Darwin. To appreciate AristotleÕs argument and its influence I assert, first, that AristotleÕs naturalistic teleology must be distinguished from PlatoÕs anthropomorphic one; second, the form of AristotleÕs arguments for teleology should be read as instances of inferences to the best explanation. On my reading, then, both NewtonÕs and PaleyÕs teleological arguments are Aristotelian while their conclusions are Platonic. Kant and DarwinÕs arguments are likewise Aristotelian while their conclusions are unique
