During the American sixties, the resurgent interest in Wilhelm Reich and the widespread impact of Marcuse's Eros and Civilisation encouraged the idea of coupling psychoanalysis and Marxism. Reich's works reminded radicals once again of the integral connection between political revolution and sexual freedom, while Marcuse's critique, a bold attempt of the mid-fifties to read Freud as a revolutionary utopian, suggested the desirability of a marriage between Marx and Freud, a marriage that would have seemed unnatural to many of the Old Left generation. Certainly, too, the writings of Norman O. Brown and Paul Goodman gave credence to the idea that sex, psychology, and radical politics were necessarily interrelated.
