The body cannot be cured without regard for the soul.

The right way to begin is to pay attention to the young, and make them just as good as possible.

The perfect human being is all human beings put together, it is a collective, it is all of us together that make perfection.

I am wiser than this man, for neither of us appears to know anything great and good; but he fancies he knows something, although he knows nothing; whereas I, as I do not know anything, so I do not fancy I do. In this trifling particular, then, I appear to be wiser than he, because I do not fancy I know what I do not know.

Wisest is he who knows he knows not.

I know nothing but the certainty of my own ignorance.

I am a fool, but I know I'm a fool and that makes me smarter than you.
