True wisdom lies in one's confession about the limits of one's knowledge.
Knowledge is our ultimate good.
Happiness is unrepented pleasure.
Fear of women love more than hate the man.
The warm love has the coldest end.
...one thing I am ready to fight for as long as I can, in word and act: that is, that we shall be better, braver and more active men if we believe it right to look for what we don't know than if we believe there is no point in looking because what we don't know we can never discover.
