Once a man gets a fixed idea, there's nothing to be done.

Man has been endowed with reason, with the power to create, so that he can add to what he's been given. But up to now he hasn't been a creator, only a destroyer. Forests keep disappearing, rivers dry up, wild life's become extinct, the climate's ruined and the land grows poorer and uglier every day.

Nothing better forges a bond of love, friendship or respect than common hatred toward something.

How unbearable at times are people who are happy, people for whom everything works out.

The more cultured a man, the less fortunate he is.

Everything on earth is beautiful, everything -- except what we ourselves think and do when we forget the higher purposes of life and our own human dignity.

The critics suppose that it is easy to write a play. They aren't aware that writing a good play is difficult and writing a bad one is twice as hard.
