“A writer in a well-known French newspaper once expressed his surprise: “Why is the notion of power raised by so many people today? Is it such an important subject? Is it so independent that it can be discussed without taking into account other problems?” This writer’s surprise amazes me. I feel skeptical about the assumption that this question has been raised for the first time in the twentieth century. Anyway, for us it is not only a theoretical question but a part of our experience. I’d like to mention only two “pathological forms” —those two “diseases of power”— fascism and Stalinism.
