Глава XIX. Сходство и различие между родом и разностью

The similarity between genus and difference lies in the fact that both embrace species and speak synonymously about species and individuals. It should be noted that what is said synonymously about something as a subject will also be said synonymously about the subject of that subject; on the contrary, what is expressed homonymously, never. The difference between a genus and a variety is that the genus is wider than the varieties subordinate to it and the three other names; that the race embraces differences with force; that the genus answers the question: what is the object, and the difference - what is the object? that the closest genus is one, but there are many differences; that genus corresponds to matter, and difference to form.
