Chapter 22

Genus and accident have this in common: that they are predicated of several things. Distinguishing peculiarities of genus and accident are: that the genus is prior to the species in which the accidents subsist, whereas the accidents are posterior to the species; that the participation oi the genus is equal, but not that of the accidents; that the accident exists antecedently in the individuals and consequently in the species, whereas the contrary is true of the genus; and that the genera are predicated of the essence of a thing, whereas the accidents are predicated of its sort, or how the thing is.
