We never know, believe me, when we have succeeded best.

If it is nothingness that awaits us, let us make an injustice of it, let us fight against destiny, even without hope of victory.

Philosophy fulfills the need to create for ourselves a single and complete concept of the world and of life.

My aim is to agitate and disturb people. I'm not selling bread; I'm selling yeast.

Man is perishing. That may be, and if it is nothingness that awaits us let us so act that it will be an unjust fate.

Cure yourself of the affliction of caring how you appear to others. Concern yourself only with how you appear before God, concern yourself only with the idea that God may have of you.

Piensa el sentimiento, siente el pensamiento." (roughly translated, "Think about the emotional and feel the intellectual")
