Note 108 — Chapter III · CATEGORIÆ.

Hobbes says:— “Now that accident (i.e. attribute) for which we give a certain name to any body, or the accident which denominates its Subject, is commonly called the Essence thereof; as rationality is the essence of a man, whiteness of any white thing, and extension the essence of a body” (Hobbes, Philosophy, ch. viii. s. 23). This topic will be found discussed, most completely and philosophically, in Mr. John Stuart Mill’s System of Logic, Book I. ch. vi. ss. 2-3; ch. vii. s. 5.
