Austrian-born Israeli Jewish Theologian, Philosopher and Writer
The great man is powerful, involuntarily and composedly powerful, but he is not avid for power. What he is avid for is the realization of what he has in mind, the incarnation of the spirit. So long as a man's power is bound to the goal, the work, the calling, it is, in itself, neither good nor evil, only a suitable or unsuitable instrument. But as soon as this bond with the goal is broken off or loosened, and the man ceases to think of power as the capacity to do something, but thinks of it as a possession, then his power, being cut off and self-satisfied, is evil and corrupts the history of the world.
Man's great guilt does not lie in the sins he commits, for temptation is great and his strength is limited. Man's great guilt lies in the fact that he can turn away from evil at any moment, and yet he does not.
