by Herbert Marcuse
He was called the guru of the student movements in the 1960s.
Posner accused Marcuse of wrongly believing that polymorphous perversity would help to create a utopia and that sex has the potential to be a politically subversive force. Writing in Public Intellectuals: A Story of Decline (2001), he suggested that “1960s radicals”, influenced by Marcuse, claimed that “sexual promiscuity would undermine capitalism” but have been proven wrong.

the author proposes a non-repressive society, attempts a synthesis of the theories of Karl Marx and Sigmund Freud
an improvement over the previous attempt to synthesize Marxist and psychoanalytic theory by the psychoanalyst Wilhelm Reich.
He contends that Freud’s argument that repression is needed by civilization to persist is mistaken, as Eros is liberating and constructive.
Freud claimed that a clash between Eros and civilization results in the history of Man being one of his repression: “Our civilization is, generally speaking, founded on the suppression of instincts.” Sex produces the energy, and it is repressed so the energy can be channeled into progress — but the price of progress is the prevalence of guilt instead of happiness.[3] “Progress”, for Marcuse, is a concept that provides the explanation and excuse of why the system has to continue; it is the reason the happiness of people is sacrificed (see also “pleasure principle“).
The economist Richard Posner, writing in Sex and Reason, maintained that Eros and Civilization contains “political and economic absurdities” but also interesting observations about sex and art. He credited Marcuse with providing arguments that made his work a critique of conventional sexual morality superior to Bertrand Russell‘s Marriage and Morals (1929), but accused Marcuse of wrongly believing that polymorphous perversity would help to create a utopia and that sex has the potential to be a politically subversive force.

Marcuse’s point here is that while work is necessary for the maintenance of life, in our society there has been a transition from the basic amount of work needed to maintain life to what we might call surplus work. There is a distinction here between the work that is needed for one’s satisfaction and work that is needed for the apparatus. The worker has no control insofar as he has no say in what his wages will be and cannot determine the amount of work that is needed to meet his needs. Work in a capitalist society extends itself beyond what is required for the satisfaction of the worker to what will maximize profit for the capitalist. The “pre-established function” of the worker is to produce commodities and maximize profit for the capitalist. The worker must work to live but the conditions under which she works is determined by the apparatus.
Being used by the apparatus requires conformity with the apparatus. This is what Marcuse means by the performance principle. Members of society must perform according to the dictates of their pre-established function. This performance requires the restriction of the libido. The worker must be manipulated in such a way so that these restrictions seem to function as rational, external objective laws which are then internalized by the individual. The desires of the individual must conform to the desires of the apparatus. The individual must define himself as the apparatus defines all humanity. As Marcuse puts it, “he desires what he is supposed to desire” (Marcuse 1955: 46).
Marcuse’s criticism of western philosophy is very similar to recent criticisms by feminists and Africana philosophers. That is, philosophy tends to treat human beings as pure, abstract consciousness. The body and the passions are to be subdued by reason or Logos. Marcuse does not intend to subjugate Logos (reason) to Eros (desire). He simply wants to return Eros to its proper place as equal to Logos. It is Freud who recognizes the central role of Eros as a motivating factor in human action.
On March 7, 1974 Marcuse gave a paper at Stanford University entitled, “Marxism and Feminism”. In it he states:
I believe the women’s liberation movement today is, perhaps the most important and potentially the most radical political movement that we have. (Marcuse 2005: 165)
For Marcuse, the women’s liberation movement was important not only for the liberation of women, but also for the liberation of all oppressed people in our society. His hope was that the struggle for the liberation of women would create a new type of performance principle and aid in the cultivation of a new sensibility. In short, certain feminine qualities would replace brutish, violent, masculine qualities. Marcuse actually advocated a form of androgyny.
