“Freedom gives us a chance to realize our human and individual uniqueness.”
Journal entry (28 March 1959)
Working and Thinking on the Waterfront (1969)
Context: The significant point is that people unfit for freedom — who cannot do much with it — are hungry for power. The desire for freedom is an attribute of a "have" type of self. It says: leave me alone and I shall grow, learn, and realize my capacities. The desire for power is basically an attribute of a "have-not" type of self. If Hitler had had the talents and the temperament of a genuine artist, if Stalin had had the capacity to become a first-rate theoretician, if Napoleon had had the makings of a great poet or philosopher they would hardly have developed the all-consuming lust for absolute power.
Freedom gives us a chance to realize our human and individual uniqueness. Absolute power can also bestow uniqueness: to have absolute power is to have the power to reduce all the people around us to puppets, robots, toys, or animals, and be the only man in sight. Absolute power achieves uniqueness by dehumanizing others.
To sum up: Those who lack the capacity to achieve much in an atmosphere of freedom will clamor for power.

Context: We do not "come into" this world; we come out of it, as leaves from a tree. As the ocean "waves," the universe "peoples." Every individual is an expression of the whole realm of nature, a unique action of the total universe. This fact is rarely, if ever, experienced by most individuals. Even those who know it to be true in theory do not sense or feel it, but continue to be aware of themselves as isolated "egos" inside bags of skin.
