Context

“Accordingly, for the apprehension of truth, the speculative reason is perfected by understanding; the practical reason, by counsel. In order to judge aright, the speculative reason is perfected by wisdom; the practical reason by knowledge. The appetitive power, in matters touching a man's relations to another, is perfected by piety; in matters touching himself, it is perfected by fortitude against the fear of dangers; and against inordinate lust for pleasures, by fear, according to Prov. 15:27: "By the fear of the Lord every one declineth from evil," and Ps. 118:120: "Pierce Thou my flesh with Thy fear: for I am afraid of Thy judgments."” source
