Anton Chekhov

When a lot of remedies are suggested for a disease, that means it cannot be cured.

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, and the climate's ruined and the land grows poorer and uglier every day.- from Uncle Vanya

He who desires nothing, hopes for nothing, and is afraid of nothing, cannot be an artist.
