I'm a pessimist. But I'm a pessimist with a sense of responsibility.

A pessimist sees the difficulty in every opportunity; an optimist sees the opportunity in every difficulty.

A pessimist is a well-informed optimist.

Let me declare expressly that in the days when mankind was not yet ashamed of its cruelty, life on earth was more cheerful than it is now that pessimists exist.

Remember that a man, a true man, never hates. His rages and his bad moods never last beyond the present moment-like electric shocks.

Everything in the world displeases me: but, above all, my displeasure in everything displeases me.
