belong to _Quantum_, Change to _Quale_, Generation, simple and absolute, to Essence or Substance.[93] New relations may become predicable of a thing, without any change in the thing itself, but simply by changes in other things.[94] [Footnote 84: Simplikius ap.

Dexippus, and after him Simplikius, observe justly, that the characteristic mark of [Greek: prô/tê ou)si/a] is this very circumstance of being _unum numero_, which belongs in common to all [Greek: prô=|tai ou)si/ai], and is indicated by the Proper name: [Greek: lu/sis de\ touo/tou, o(/ti au)to\ to\ mi/an ei)=nai a)rithmô=|, koino/s e)sti lo/gos]. (Simpl. in Categor., fol. 22 [Greek: D]].; Dexippus, book ii. sect. 18, p. 57, ed. Spengel.)] [Footnote 86: Aristot. Categ. p. 2, b. 5.

And we can no more imagine a substance without attributes, than we can imagine attributes without a substance." (System of Logic, bk. i. ch. iii. p. 61, 6th ed.)] [Footnote 87: Aristot. Physic. ii. p. 194, b. 8. [Greek: e)/ti tô=n pro/s ti ê( u(/lê; a)/llô| ga\r ei)/dei a)/llê u(/lê.] Plotinus puts this correctly, in his criticisms on the Stoic Categories; criticisms which on this point equally apply to the Aristotelian: [Greek: pro/s ti ga\r to\ u(pokei/menon, ou) pro\s to\ e)n au)tô=|, a)lla\ pro\s to\ poiou=n ei)s au)to/, kei/menon.
