power

The word power has a twofold meaning. One is the possession of power over somebody, the ability to dominate him; the other meaning is the possession of power to do something, to be able, to be potent. The latter meaning has nothing to do with domination; it expresses mastery in the sense of ability. (…) Thus power can mean one of two things, domination or potency. Far from being identical, these two qualities are mutually exclusive. (…) To the extent to which an individual is potent, that is, able to realize his potentialities on the basis of freedom and integrity of his self, he does not need to dominate and is lacking the lust for power. Power, in the sense of domination, is the perversion of potency, just as sexual sadism is the perversion of sexual love. ― (1941a: Escape from Freedom, New York (Farrar and Rinehart) 1941, p. 162.)
