 612 animal. For of predicates some are predicated of one thing alone, as individuals, for instance, "Socrates," and "this man," and "this thing;" but others are predicated of many, as genera, are predicated species, differences, properties, and accidents, predicated in common, but not peculiarly to any one. Now genus is such as "animal," species as "man," difference as "rational," property as "risible," accident as " white," "black," "to sit." From such things then, as are predicated of one thing only, genera differ in that they are predicated of many, but on the other hand, from those which are predicated many and from species, (they differ) because those species are predicated of many things, yet not of those which differ in species, but in number only, for man being a species, is predicated of Socrates and Plato, who do not differ from each other in species, but in number, while animal being a genus is predicated of man, and ox, and horse, which differ also in species from each other, and not in number only. From property, moreover, genus differs because property is predicated of one species alone of which it is the property, and of the individuals under the species, as "risible" of man alone, and of men particularly, for genus is not predicated of one species, but of many things, which are also different in species. Besides, genus diners from difference and from accidents in common, because though differences and accidents in common are predicated of many things, different also in species, yet they are not so in reply to what a thing is, but (what kind of a thing) it is. For when some persons ask what that is of which these are predicated, we reply, that it is genus; but we do not assign in answer differences and accidents, since they are not predicated of a subject, as to what a thing is, but rather as to what kind of a thing it is. For in reply to the question, what kind of a thing man is, we say, that he is rational, and in answer to what kind of a thing a crow is, we say that it is black, yet
