Concerning the cosmos, in the Timaeus, the title character also tells a "likely story" in which nous is responsible for the creative work of the demiurge or maker who brought rational order to our universe. This craftsman imitated what he perceived in the world of eternal Forms. In the Philebus Socrates argues that nous in individual humans must share in a cosmic nous, in the same way that human bodies are made up of small parts of the elements found in the rest of the universe.
