Plato: The Republic

9. BOOK IX (continued)

And this is clearly seen to be the intention of the law, which is the ally of the whole city; and is seen also in the authority which we exercise over children, and the refusal to let them be free until we have established in them a principle analogous to the constitution of a state, and by cultivation of this higher element have set up in their hearts a guardian and ruler like our own, and when this is done they may go their ways.

Yes, he said, the purpose of the law is manifest.

From what point of view, then, and on what ground can we say that a man is profited by injustice or intemperance or other baseness, which will make him a worse man, even though he acquire money or power by his wickedness?

From no point of view at all.

What shall he profit, if his injustice be undetected and unpunished? He who is undetected only gets worse, whereas he who is detected and punished has the brutal part of his nature silenced and humanized; the gentler element in him is liberated, and his whole soul is perfected and ennobled by the acquirement of justice and temperance and wisdom, more than the body ever is by receiving gifts of beauty, strength and health, in proportion as the soul is more honourable than the body.

Certainly, he said.

To this nobler purpose the man of understanding will devote the energies of his life. And in the first place, he will honour studies which impress these qualities on his soul and disregard others?

Clearly, he said.

In the next place, he will regulate his bodily habit and training, and so far will he be from yielding to brutal and irrational pleasures, that he will regard even health as quite a secondary matter; his first object will be not that he may be fair or strong or well, unless he is likely thereby to gain temperance, but he will always desire so to attemper the body as to preserve the harmony of the soul?
