Beware of the man who does not return your blow: he neither forgives you nor allows you to forgive yourself. Maxim for Revolutionists

I am quite ready, Simmias and Cebes, that I ought to be grieved at death, if I were not persuaded that I am going to other gods who are wise and good and to men departed who are better than those whom I leave behind; and therefore I do not grieve as I might have done, for I have good hope that there is yet something remaining for the dead, and, as has been said of old, some far better thing for the good than for the evil. The Trials Of Socrates

There are two tragedies in life. One is not to get your heart's desire. The other is to get it. Man and Superman
