My good friend, you are a citizen of Athens, a city which is very great and very famous for its wisdom and power - are you not ashamed of caring so much for the making of money and for fame and prestige, when you neither think nor care about wisdom and truth and the improvement of your soul?
PlatoBut that we shall be better and braver and less helpless if we think that we ought to enquire, than we should have been if we indulged in the idle fancy that there was no knowing and no use in seeking to know what we do not know; - that is a theme upon which I am ready to fight, in word and deed, to the utmost of my power.
Plato
