“It may be in our sexuality that we are most easily enslaved, both men and women. It may be there, even as free men and women, that we find freedom hardest to keep. The politics of the flesh are the roots of power.”

Introduction
Capitalism and Freedom (1962)
Context: The free man will ask neither what his country can do for him nor what he can do for his country. He will ask rather "What can I and my compatriots do through government" to help us discharge our individual responsibilities, to achieve our several goals and purposes, and above all, to protect our freedom? And he will accompany this question with another: How can we keep the government we create from becoming a Frankenstein that will destroy the very freedom we establish it to protect? Freedom is a rare and delicate plant. Our minds tell us, and history confirms, that the great threat to freedom is the concentration of power. Government is necessary to preserve our freedom, it is an instrument through which we can exercise our freedom; yet by concentrating power in political hands, it is also a threat to freedom. Even though the men who wield this power initially be of good will and even though they be not corrupted by the power they exercise, the power will both attract and form men of a different stamp.

Context: These apparently opposed perspectives meet on the common ground of sexual conservatism. The monogamists uphold the traditional wife's "official" values: emotional commitment is inseparable from a legal/moral obligation to permanence and fidelity; men are always trying to escape these duties; it's in our interest to make them shape up. The separatists tap into the underside of traditional femininity — the bitter, self-righteous fury that propels the indictment of men as lustful beasts ravaging their chaste victims. These are the two faces of feminine ideology in a patriarchal culture: they induce women to accept a spurious moral superiority as a substitute for sexual pleasure, and curbs on men's sexual freedom as a substitute for real power.
