Book I
Chapter 17
Likeness should be studied, first, in the case of things belonging to different genera, the formula being ‘A:B = C:D’ (e.g. as knowledge stands to the object of knowledge, so is sensation related to the object of sensation), and ‘As A is in B, so is C in D’ (e.g. as sight is in the eye, so is reason in the soul, and as is a calm in the sea, so is windlessness in the air). Practice is more especially needed in regard to terms that are far apart; for in the case of the rest, we shall be more easily able to see in one glance the points of likeness. We should also look at things which belong to the same genus, to see if any identical attribute belongs to them all, e.g. to a man and a horse and a dog; for in so far as they have any identical attribute, in so far they are alike.
