“You are quite right, I changed my mind and do no longer speak of “radical evil.” … It is indeed my opinion now that evil is never “radical,” that it is only extreme, and that it possesses neither depth nor any demonic dimension. It can overgrow and lay waste the whole world precisely because it spreads like a fungus on the surface. It is “thought-defying,” as I said, because thought tries to reach some depth, to go to the roots, and the moment it concerns itself with evil, it is frustrated because there is nothing. That is its “banality.” Only the good has depth that can be radical.(letter to Scholem from December 1964)”

“The trouble with lying and deceiving is that their efficiency depends entirely upon a clear notion of the truth that the liar and deceiver wishes to hide.”

“Revolutionaries do not make revolutions. The revolutionaries are those who know when power is lying in the street and then they can pick it up.”

“Power and violence are opposites; where the one rules absolutely, the other is absent. Violence appears where power is in jeopardy, but left to its own course it ends in power's disappearance.”

“No punishment has ever possessed enough power of deterrence to prevent the commission of crimes. On the contrary, whatever the punishment, once a specific crime has appeared for the first time, its reappearance is more likely than its initial emergence could ever have been.”

“No cause is left but the most ancient of all, the one, in fact, that from the beginning of our history has determined the very existence of politics, the cause of freedom versus tyranny.”
