Disputationes tres

And therefore it is shameful to wish to invent or establish some similarity, and indeed such a one, in disparate or heterogeneous things. For those things which, as Cyril testifies, are compared and collated with one another are of the same nature; nor do they receive a comparison from their essence, but from the accidents by which they differ. For it will seem ridiculous, says Cyril, for anyone to compare things that are naturally diverse, just as if someone were to contend that the sun is more shining than wood. For since heterogeneous things are joined by no nature, they cannot be compared with each other; nor can one be said to be similar to another. For one does not rightly compare a man to an ass, or to a sheep; but a man to a man, and a sheep to a sheep. For comparisons are accustomed to be made within the same species; and although sometimes things that are different in species may receive a comparison of quality, it is done less correctly. For things that are similar to something are not one with it according to nature.
