Abstract

The vast majority of canonical early modern authors reject Aristotelian physics and metaphysics. Instead, many of them are mechanists, that is, they explain all natural change in the material world simply through the motions and collisions of inertial matter in motion. This typically means that they deny that there is immanent teleology in the natural world; sometimes, it even means eliminating purposiveness from natural philosophy altogether. Thus, some writers attempt to provide explanations of natural phenomena that do not rely on teleology. Because this proves enormously difficult, others retain, or reintroduce, teleology in various forms. The section “Rejections of Teleology” explores the reasons why certain early modern authors reject teleology more or less generally. The section “Defenses of Extrinsic Teleology” shows that quite a few writers embrace extrinsic teleology: they hold that many natural things and processes have ends in virtue of being part of God’s plan for the world. Some of these authors also advocate the use of teleology in natural philosophy, for instance, to discover natural laws. Finally, the section “Defenses of Immanent Teleology” shows that there are a few early modern philosophers and scientists who go even further than that, insisting on the need for immanent teleology in the natural world.
