  Fragment B12 ends with a further discussion of mixture and separation, and Anaxagoras’ enunciation of what has come to be called the “Principle of Predominance.” After reasserting that no ingredient is ever fully dissociated or separated from any other (except for nous, which is not an ingredient), Anaxagoras adds that all nous is alike (that is, cosmic nous and mind in us share the same nature), but “Nothing else is like anything else, but each one is and was most manifestly those things of which there are the most in it.” Thus, something is hot, if hot predominates over the cold in it, flesh if flesh predominates over other ingredients, and so on. The principle does not claim that there is any single predominating ingredient at each place in the mixture. Rather, the predominance seems to be along numerous lines of possibility: more flesh than blood, more hot than cold, more red than green, and so on (Furley 2002).  This need not mean that there is more humanity than doghood in a human being (indeed it could not mean this, on the account advanced in this article, which rules out dogs and humans as Anaxagorean ingredients). Rather, to be a human being is to have a certain set of predominant characteristics arranged in a certain way (that arrangement may be the work of soul — perhaps nous — in a living thing).
