The Complete Works of Plato

by Plato

SOCRATES: For if a man, my dear Alcibiades, has the power to do what he likes, but has no understanding, what is likely to be the result, either to him as an individual or to the state—for example, if he be sick and is able to do what he likes, not having the mind of a physician—having moreover tyrannical power, and no one daring to reprove him, what will happen to him? Will he not be likely to have his constitution ruined?

Sounds familiar.
