The general doctrine laid down by Aristotle, Metaphys. N. p. 1087, b. 34, seq., about the universality of [Greek: me/tron] as pervading all the Categories, is analogous to the passage above referred to in the Politicus of Plato, and implies the Relativity involved more or less in all predicates.] [Footnote 93: Aristot. Metaph. N. p. 1088, a. 29: [Greek: sêmei=on de\ o(/ti ê(/kista ou)si/a tis kai\ o)/n ti _to\ pro\/s ti_ to\ mo/non mê\ ei)=nai ge/nesin au)tou= mêde\ phthora\n mêde\ ki/nêsin, ô(/sper kata\ to\ poso\n au)/xêsis kai\ phthi/sis, kata\ to\ poio\n a)lloi/ôsis, kata\ to/pon phora/, kata\ tê\n ou)si/an ê( a(plê= ge/nesis kai\ phthora/.] Compare K. p. 1068, a. 9: [Greek: a)na/gkê trei=s ei)=nai kinê/seis, poiou=, posou=, to/pou. kat' ou)si/an d' ou)/, dia\ to\ mêthe\n ei)=nai ou)si/a| e)nanti/on, ou)de\ tou= pro/s ti.] Also Physica, v. p. 225, b. 11: [Greek: e)nde/chetai ga\r thate/rou metaba/llontos a)lêtheu/esthai tha/teron mêde\n meta/ballon.] See about this passage Bonitz and Schwegler's notes on Metaphys. p. 1068.] [Footnote 94: Hobbes observes (First Philosophy, part ii. ch. xi. 6): "But we must not so think of Relation as if it were an accident differing from all the other accidents of the relative; but one of them, namely, that by which the comparison is made. For example, the likeness of one white to another white, or its unlikeness to black, is the same accident with its whiteness." This may be true about the relations Like and Unlike (see Mr. John Stuart Mill, Logic, ch. iii. p. 80, 6th ed.) But, in Relations generally, the _fundamentum_ may be logically distinguished from the Relation itself. Aristotle makes the same remarks upon [Greek: to\ sumbebêko\s] as upon [Greek: to\ pro/s ti]:--That it verges upon Non-ens; and that it has no special mode of being generated or destroyed.
