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. And this "nous" must be in the "genos" of being a cause of all particular things as particular things.
