Quick Summary

The Monadology is a philosophical work by Gottfried Wilhelm Leibniz that outlines his theory of monads. Leibniz proposed that monads are the fundamental, immaterial substances that constitute the universe. Each monad is unique, indestructible, and dynamic, with its properties determined by its perceptions and appetites.123

Monads lack spatial extension and do not interact causally with each other. Instead, their apparent interactions are explained by a "preestablished harmony" established by God at the beginning of time, synchronizing all monads. The material world, in Leibniz's view, is composed of collections of these monads.14
