I beseech you to treasure up in your hearts these my parting words: Be ashamed to die until you have won some victory for humanity.

Better one thorn pluck'd out than all remain.

He can afford to be a fool.

Enjoy in happiness the pleasures which each hour brings with it.

To grow a philosopher's beard.
