There is no other start to philosophy but wonder.

It is our duty to select the best and most dependable theory that human intelligence can supply, and use it as a raft to ride the seas of life.

You ought not attempt to cure the eyes without the head, or the head without the body, so neither ought you attempt to cure the body without the soul.

The man who hath music in his soul will be most in love with the loveliest.

More will be accomplished, and better, and with more ease, if every man does what he is best fitted to do, and nothing else.

But this is not difficult, O Athenians! to escape death; but it is much more difficult to avoid depravity, for it runs swifter than death. And now I, being slow and aged, am overtaken by the slower of the two; but my accusers, being strong and active, have been overtaken by the swifter, wickedness. And now I depart, condemned by you to death; but they condemned by truth, as guilty of iniquity and injustice: and I abide my sentence, and so do they. These things, perhaps, ought so to be, and I think that they are for the best.

Friends should have all things in common.
