Context

“(Cf. the Definition of Appetite, III. ix. note, and Def. of the Emotions, i.) . Therefore, every man, solely by the laws of his nature, desires the one, and shrinks from the other, &c. Q.E.D. PROP. XX. The more every man endeavours, and is able to seek what is useful to him—in other words, to preserve his own being—the more is he endowed with virtue; on the contrary, in proportion as a man neglects to seek what is useful to him, that is, to preserve his own being, he is wanting in power. Proof.—Virtue is human power, which is defined solely by man's essence” source
