Since all of us desire to be happy, and since we evidently become so on account of our use—that is our good use—of other things, and since knowledge is what provides this goodness of use and also good fortune, every man must, as seems plausible, prepare himself by every means for this: to be as wise as possible. Right?

I know you won't believe me, but the highest form of Human Excellence is to question oneself and others.

Those then who know not wisdom and virtue, and are always busy with gluttony and sensuality, go down and up again as far as the mean; and in this region they move at random throughout life, but they never pass into the true upper world; thither they neither look, nor do they ever find their way, neither are they truly filled with true being, nor do they ever taste of pure and abiding pleasure.

The soul then, as being immortal, and having been born again many times, and having seen all things that exist, whether in this world or in the world below, has knowledge of them all . . . all enquiry and all learning is but recollection.

If I can assign names as well as pictures to objects, the right assignment of them we may call truth, and the wrong assignment of them falsehood.

Flattery is like friendship in show, but not in fruit.

All men's souls are immortal, but the souls of the righteous are immortal and divine.
