With reasonable men, I reason; with humane men, I plead; but with tyrants I give no quarter.
Just as love is an orientation which refers to all objects and is incompatible with the restriction to one object, so is reason a human faculty which must embrace the whole of the world with which man is confronted.
Those who will not reason, are bigots, those who cannot, are fools, and those who dare not, are slaves.
I always disagree, however, when people end up saying that we can only combat Communism, Fascism or what not if we develop an equal fanaticism. It appears to me that one defeats the fanatic precisely by not being a fanatic oneself, but on the contrary by using one's intelligence.
