Homoiomereia (Gr. ὁμοιομέρεια) describes a fundamental Stoic assumption about the structure of matter: that the parts of the cosmos are similarly or identically constituted. This is closely connected to the idea of Apokatastasis — because the cosmic parts are homoiomerous, restoration can occur with exact precision. The principle also supports the Stoic concept of Sympatheia (universal interconnectedness), since parts that share the same structure are necessarily related to one another.
