Universal (logic)

Definition and stakes

Portrait of Georg Wilhelm Friedrich Hegel Georg Wilhelm Friedrich Hegel,  Science of Logic (1816)

“ But the universal of the notion is not a mere sum of features common to several things, confronted by a particular which enjoys an existence of its own. It is, on the contrary, self-particularising or self-specifying, and with undimmed clearness finds itself at home in its antithesis. For the sake both of cognition and of our practical conduct, it is of the utmost importance that the real universal should not be confused with what is merely held in common. ”

“ When the universal is made a mere form and co-ordinated with the particular, as if it were on the same level, it sinks into a particular itself. Even common sense in every-day matters is above the absurdity of setting a universal beside the particulars. Would any one, who wished for fruit, reject cherries, pears, and grapes, on the ground that they were cherries, pears, or grapes, and not fruit? But when philosophy is in question, the excuse of many is that philosophies are so different, and none of them is the philosophy,—that each is only a philosophy. ”

“ The traditional Logic of the text-books, when it reasons from universals to their subalternate particulars, or derives particular conclusions from universal premises, does so by tacitly and, in general, by unjustifiably assuming the external existence of the objects reasoned about, while all the time still sundering external and internal. Reasoning itself is, to be sure, experience, but is, by hypothesis, experience of internal meanings, not of the external meanings which are taken, by this sort of thinking, to be the Reality. ”
