“No one doubts that an ordinary man can get on with this world: but we demand not strength enough to get on with it, but strength enough to get it on. Can he hate it enough to change it, and yet love it enough to think it worth changing? Can he look up at its colossal good without once feeling acquiescence? Can he look up at its colossal evil without once feeling despair? Can he, in short, be at once not only a pessimist and an optimist, but a fanatical pessimist and a fanatical optimist? Is he enough of a pagan to die for the world, and enough of a Christian to die to it? In this combination, I maintain, it is the rational optimist who fails, the irrational optimist who succeeds. He is ready to smash the whole universe for the sake of itself.”
“You know, any man can get any woman he wants if he tries hard enough, there's nothing in that, but once he's got her, only a man who thinks the world of women can get rid of her without humiliating her.”
“The pessimist says, ‘It can’t get any worse!’ And the optimist replies, ‘Oh yes it can!”
“I am an optimist, unrepentant and militant. After all, in order not to be a fool, an optimist must know what a sad place the world can be. It is only the pessimist who finds this out anew every day.”
“The man who is a pessimist before 48 knows too much; if he is an optimist after it he knows too little.”
“Don't ever become a pessimist, Ira; a pessimist is correct oftener than an optimist, but an optimist has more fun--and neither can stop the march of events.”
