Ἐναντία

According to Aristotle the contraries are joined to each other in six ways, and their conjunction, in four ways, creates a contrariety.¹ 'Contraries' is the name for the [elements] which are very different from each other or the ones which make each other false. But this being said, anyone starting from these [principles] would not be able to demonstrate that one element is contrary only to one other, since one can take even many elements whose difference from each other is great, in the same kind: 'yellow' and 'pale' are both very distant from 'white', but they are also able to make the white false, and that [white] is able to make these false. But one can take elements whose difference from each other is great even in different kinds. For the two differ [from each other], one to one.²
