  Anaxagoras is adamant that nous is completely different from the ingredients that constituted the original mixture. It is the only thing to which the Everything-in-Everything principle does not apply. Mind is present to some things, but it is not an ingredient or share as flesh and blood are ingredients in a dog (B11: “In everything there is a share of everything except nous, but there are some things in which nous, too, is present”). In B12 (the longest extant fragment), Anaxagoras claims that if nous were just another ingredient it could neither know nor rule in the way that it does.
