"[Heraclitus] did not require humans or their..." - Quote by Friedrich Nietzsche

“When we talk in company we lose our unique tone of voice, and this leads us to make statements which in no way correspond to our real thoughts.”

“Of what is great one must either be silent or speak with greatness. With greatness--that means cynically and with innocence.”

“The discipline of suffering, of great suffering- do you not know that only this discipline has created all enhancements of man so far? That tension of the soul in unhappiness which cultivates its strength, its shudders face to face with great ruin, its inventiveness and courage in enduring, preserving, interpreting, and exploiting suffering, and whatever has been granted to it of profundity, secret, mask, spirit, cunning, greatness- was it not granted to it through suffering, through the discipline of great suffering?”

“Men who are lovers of wisdom [i.e., philosophers] must be inquirers into many things.”

“I advance in life, I grow more simple, and I become more and more patriotic for humanity.”

“Somewhere somebody must have some sense. Men must see that force begets force, hate begets hate, toughness begets toughness. And it is all a descending spiral, ultimately ending in destruction for all and everybody. Somebody must have sense enough and morality enough to cut off the chain of hate and the chain of evil in the universe. And you do that by love.”

“Abandon knowledge and your worries are over.”

“The problem in my life and other people's lives is not the absence of knowing what to do but the absence of doing it.”

“When you learn, teach, when you get, give.”
