rational is difference, but black is accident. When however we are asked what man is, we answer, an animal, buy animal is the genus of man, so that from genus being predicated of many, it is diverse from individuals which are predicated of one thing only, but from being predicated of things different in species, it is distinguished from such as are predicated as species or as properties. Moreover, because it is predicated in reply to what a thing is. it is distinguished from differences and from accidents commonly, which are severally predicated of what they are predicated, not in reply to what a thing is, but what kind of a thing it is, or in what manner it subsists: the description therefore of the conception of genus, which has been enunciated, contains nothing superfluous, nothing deficient.[1]
10. Species predicated of every form, and under genus. Cf. Crakanthorpe's Log. lib. ii.; Aldrich and HillSpecies indeed is predicated of every form, according to which it is said, "form is first worthy of imperial sway;"[2] still that is called species also, which is under the genus stated, according to which we are accustomed to call man a species of animal, animal being genus, but white a species of colour, and triangle of figure. Nevertheless, if when we assign the genus, we make mention of species, saying that which is predicated of many things differing in species, in reply to what a thing is, and call species that which is under the assigned genus, we ought to know that, since genus is the genus of something, and species the species of something, each of each, we must necessarily use both in the definitions of both. They assign, therefore, species thus: species is what is arranged under genus, and of which genus is predicated in reply to what a tiling is:11. The latter predicated of the former "in quid." moreover, thus species is what is predicated of many things differing in number, in reply to what a thing is. This explanation, however, belongs to the most special,
- ↑ Porphyry does not recognise the distinction between "quale quid " and "quale," (cf. Aldrich, Abelard de Gen. et Spe. ed. Cousin,) but makes difference, property, and accident to be all predicated (
Greek characters): Boethius distinguishes quale in substantiâ, from quale non in substantiâ. Moreover, Porphyry makes difference to be always predicated de specie dilferentibus; upon his consideration of property, vide note to ch. 4, Isagog.
