If genera are different and co-ordinate, their differentiae are themselves different in kind.
But where one genus is subordinate to another, there is nothing to prevent their having the same differentiae: for the greater class is predicated of the lesser, so that all the differentiae of the predicate will be differentiae also of the subject.
Correlatively, the "status" of
differentiae only becomes "an unsolvable problem if one supposes that Categories is offering up an ontology" (p.
Guido d'Eu even draws into his theoretical web the psalm tone
differentiae, an aspect of practice more conventional than logical in nature.
Arguably, however, if one adverts to certain parallels in Aristotle's reasoning manifested in his considerations of method and his use of
differentiae in biological analyses, his reflections on politeia are set into greater relief.
This same point, in fact, appears in other terms in 8.2, where Aristotle characterizes substance, in the sense of actuality, as a differentia or
differentiae of substance in the sense of matter.
(18) Finally, when commenting on Aristotle's claims in chapter 11 he says that "A mortal rational animal is a man" is single but would become multiple if "and" should be inserted between the
differentiae. (19) Bacon, on the other hand, gives no indication in 2.192 that he is even aware of a discussion about the implication of such pauses for single statements.

differentiae enim per se diversificant speciem." Compare De malo, q.
Marenbon thus examines Abelard's ontology, how he understood substance and the difference between accidents and
differentiae, the possibility of language (especially helpful here is Marenbon's explanation of the difference between voces and sermones) as well as its relationship to forms, human perception, and knowledge, and the role of universals.
Os Doutores perceberao minuciosamente as numerosas
differentiae, que na situacao juridica do vassalo derivam do seu ser dominus e nao usufructuarius: cabe-lhe, como ha pouco se dizia, a reivindicatio e nao a simples acao confessoria prevista para as servidoes (e, portanto, para o usufruto) (39); torna seus os frutos pendentes, enquanto o usufrutuario os conquista unicamente com a percepcao (40); pode constituir direitos reais limitados sobre o fundo, poder que e negado ao usufrutuario (41).
Whitney is, as should now be apparent, among the supreme colorists of contemporary painting, but what's amazed me in his drawings has been his mysterious ability to communicate the variable weights and densities of color, as he does in his paintings-without actually using color at all, instead relying on pure line to express, as if through metaphor, chromatic
differentiae.
[...] Altero modo possunt accipi practicum et speculativum, non ut sunt
differentiae determinatae et contrariae, sed ablatis imperfectionibus, quibus inter se opponuntur: et hoc modo conveniunt scientiae divinae>>.
