Perhaps I know best why it is man alone who laughs; he alone suffers so deeply that he had to invent laughter.

I assess the power of a will by how much resistance, pain, torture it endures and knows how to turn to its advantage.

We should consider every day lost on which we have not danced at least once. And we should call every truth false which was not accompanied by at least one laugh.

What makes us heroic? Confronting simultaneously our supreme suffering and our supreme hope.

He who has a why to live for can bear almost any how.

Man must be sustained in suffering by a hope so high that no conflict with actuality can dash it-so high, indeed, that no fulfilment can satisfy it: a hope reaching out beyond this world.
