Proceed, then, Lucilius, and hasten, lest you yourself be compelled to learn in your old age, as is the case with me. Nay, you must hasten all the more, because for a long time you have not approached the subject, which is one that you can scarcely learn thoroughly when you are old. “How much progress shall I make?” you ask. Just as much as you try to make. Why do you wait? Wisdom comes haphazard to no man. Money will come of its own accord; titles will be given to you; influence and authority will perhaps be thrust upon you; but virtue will not fall upon you by chance. Neither is knowledge thereof to be won by light effort or small toil; but toiling is worth while when one is about to win all goods at a single stroke. For there is but a single good—namely, that which is honourable; in all those other things of which the general opinion approves, you will find no truth or certainty. Why it is, however, that there is but one good, namely, that which is honourable, I shall now tell you, inasmuch as you judge that in my earlier letter459 I did not carry the discussion far enough, and think that this theory was commended to you rather than proved. I shall also compress the remarks of other authors into narrow compass.
Everything is estimated by the standard of its own good. The vine is valued for its productiveness and the flavour of its wine, the stag for his speed. We ask, with regard to beasts of burden, how sturdy of back they are; for their only use is to bear burdens. If a dog is to find the trail of a wild beast, keenness of scent is of first importance; if to catch his quarry, swiftness of foot; if to attack and harry it, courage. In each thing that quality should be best for which the thing is brought into being and by which it is judged. And what quality is best in man? It is reason; by virtue of reason he surpasses the animals, and is surpassed only by the gods. Perfect reason is therefore the good peculiar to man; all other qualities he shares in some degree with animals and plants. Man is strong; so is the lion. Man is comely; so is the peacock. Man is swift; so is the horse. I do not say that man is surpassed in all these qualities. I am not seeking to find that which is greatest in him, but that which is peculiarly his own. Man has body; so also have trees. Man has the power to act and to move at will; so have beasts and worms. Man has a voice; but how much louder is the voice of the dog, how much shriller that of the eagle, how much deeper that of the bull, how much sweeter and more melodious that of the nightingale! What then is peculiar to man? Reason. When this is right and has reached perfection, man’s felicity is complete. Hence, if everything is praiseworthy and has arrived at the end intended by its nature, when it has brought its peculiar good to perfection, and if man’s peculiar good is reason; then, if a man has brought his reason to perfection, he is praiseworthy and has reached the end suited to his nature. This perfect reason is called virtue, and is likewise that which is honourable.
Hence that in man is alone a good which alone belongs to man. For we are not now seeking to discover what is a good, but what good is man’s. And if there is no other attribute which belongs peculiarly to man except reason, then reason will be his one peculiar good, but a good that is worth all the rest put together. If any man is bad, he will, I suppose, be regarded with disapproval; if good, I suppose he will be regarded with approval. Therefore, that attribute of man whereby he is approved or disapproved is his chief and only good. You do not doubt whether this is a good; you merely doubt whether it is the sole good. If a man possess all other things, such as health, riches, pedigree,460 a crowded reception-hall, but is confessedly bad, you will disapprove of him. Likewise, if a man possess none of the things which I have mentioned, and lacks money, or an escort of clients, or rank and a line of grandfathers and great-grandfathers, but is confessedly good, you will approve of him. Hence, this is man’s one peculiar good, and the possessor of it is to be praised even if he lacks other things; but he who does not possess it, though he possess everything else in abundance, is condemned and rejected. The same thing holds good regarding men as regarding things. A ship is said to be good not when it is decorated with costly colours, nor when its prow is covered with silver or gold or its figurehead461 embossed in ivory, nor when it is laden with the imperial revenues462 or with the wealth of kings, but when it is steady and staunch and taut, with seams that keep out the water, stout enough to endure the buffeting of the waves’ obedient to its helm, swift and caring naught for the winds. You will speak of a sword as good, not when its sword-belt is of gold, or its scabbard studded with gems, but when its edge is fine for cutting and its point will pierce any armour. Take the carpenter’s rule: we do not ask how beautiful it is, but how straight it is. Each thing is praised in regard to that attribute which is taken as
