Abstract

Nature, according to Cavendish, has “an Infinite Natural power, that is, a power to produce infinite effects in her own self, by infinite changes of Motions” (OEP II.XIV: 220). While Cavendish mentions powers with respect to human beings, medicines, occasional causes, and other entities, these powers are really just the power of self-moving matter to cause changes in the world. This paper examines why Cavendish attributes the power self-motion to matter, what this power is, how it arose, how it is enacted, and its limitations. In doing so, I discuss her views on causation, perception, and motion, and argue that motion is not reducible to change in mereological facts.
