The form of law which I propose would be as follows: In a state which is desirous of being saved from the greatest of all plagues-not faction, but rather distraction-there should exist among the citizens neither extreme poverty nor, again, excessive wealth, for both are productive of great evil . . . Now the legislator should determine what is to be the limit of poverty or of wealth.

'But the man who is ready to taste every form of knowledge, is glad to learn and never satisfied - he's the man who deserves to be called a philosopher, isn't he?'

I would fain grow old learning many things.

I shall never alter my ways, not even if I have to die many times.

Your dog is your only philosopher.
