The Supremacy of Reason

13 Our inquiry, accordingly, is whether reason is sovereign over the emotions. 14 We shall decide just what reason is and what emotion is, how many kinds of emotions there are, and whether reason rules over all these. 15 Now reason is the mind that with sound logic prefers the life of wisdom. 16 Wisdom, next, is the knowledge of divine and human matters and the causes of these. 17 This, in turn, is education in the law, by which we learn divine matters reverently and human affairs to our advantage. 18 Now the kinds of wisdom are rational judgment, justice, courage, and self-control. 19 Rational judgment is supreme over all of these, since by means of it reason rules over the emotions. 20 The two most comprehensive typese of the emotions are pleasure and pain; and each of these is by nature concerned with both body and soul. 21 The emotions of both pleasure and pain have many consequences. 22 Thus desire precedes pleasure and delight follows it. 23 Fear precedes pain and sorrow comes after. 24 Anger, as a person will see by reflecting on this experience, is an emotion embracing pleasure and pain. 25 In pleasure there exists even a malevolent tendency, which is the most complex of all the emotions. 26 In the soul it is boastfulness, covetousness, thirst for honor, rivalry, and malice; 27 in the body, indiscriminate eating, gluttony, and solitary gormandizing.

28 Just as pleasure and pain are two plants growing from the body and the soul, so there are many offshoots of these plants,f 29 each of which the master cultivator, reason, weeds and prunes and ties up and waters and thoroughly irrigates, and so tames the jungle of habits and emotions. 30 For reason is the guide of the virtues, but over the emotions it is sovereign.

Observe now, first of all, that rational judgment is sovereign over the emotions by virtue of the restraining power of self-control. 31 Self-control, then, is dominance over the desires. 32 Some desires are mental, others are physical, and reason obviously rules over both. 33 Otherwise, how is it that when we are attracted to forbidden foods we abstain from the pleasure to be had from them? Is it not because reason is able to rule over appetites? I for one think so. 34 Therefore when we crave seafood and fowl and animals and all sorts of foods that are forbidden to us by the law, we abstain because of domination by reason. 35 For the emotions of the appetites are restrained, checked by the temperate mind, and all the impulses of the body are bridled by reason.
