Section 9: Virtue Is Not Chosen for Pleasure explained simply

IX. “But,” says our adversary, “you yourself only practise virtue because you hope to obtain some pleasure from it.” In the first place, even though virtue may afford us pleasure, still we do not seek after her on that account: for she does not bestow this, but bestows this to boot, nor is this the end for which she labours, but her labour wins this also, although it be directed to another end. As in a tilled-field, when ploughed for corn, some flowers are found amongst it, and yet, though these posies may charm the eye, all this labour was not spent in order to produce them—the man who sowed the field had another object in view, he gained this over and above it—so pleasure is not the reward or the cause of virtue, but comes in addition to it; nor do we choose virtue because she gives us pleasure, but she gives us pleasure also if we choose her. The highest good lies in the act of choosing her, and in the attitude of the noblest minds, which when once it has fulfilled its function and established itself within its own limits has attained to the highest good, and needs nothing more: for there is nothing outside of the whole, any more than there is anything beyond the end. You are mistaken, therefore, when you ask me what it is on account of which I seek after virtue: for you are seeking for something above the highest. Do you ask what I seek from virtue? I answer. Herself: for she has nothing better; she is her own reward. Does this not appear great enough, when I tell you that the highest good is an unyielding strength of mind, wisdom, magnanimity, sound judgment, freedom, harmony, beauty? Do you still ask me for something greater, of which these may be regarded as the attributes? Why do you talk of pleasures to me? I am seeking to find what is good for man, not for his belly; why, cattle and whales have larger ones than he.
