Like their contemporary, R. D. Laing, and like Reich before them, Deleuze and Guattari make a connection between psychological repression and social oppression. By means of their concept of desiring-production, however, their manner of doing so is radically different. They describe a universe composed of desiring-machines, all of which are connected to one another: "There are no desiring-machines that exist outside the social machines that they form on a large scale; and no social machines without the desiring machines that inhabit them on a small scale." When they insist that a social field may be invested by desire directly, they oppose Freud's concept of sublimation, which posits an inherent dualism between desiring-machines and social production. This dualism, they argue, limited and trapped the revolutionary potential of the theories of Laing and Reich. Deleuze and Guattari develop a critique of Freud and Lacan's psychoanalysis, anti-psychiatry, and Freudo-Marxism (with its insistence on a necessary mediation between the two realms of desire and the social). Deleuze and Guattari's concept of sexuality is not limited to the interaction of male and female gender roles, but instead posits a multiplicity of flows that a "hundred thousand" desiring-machines create within their connected universe; Deleuze and Guattari contrast this "non-human, molecular sexuality" to "molar" binary sexuality: "making love is not just becoming as one, or even two, but becoming as a hundred thousand," they write, adding that "we always make love with worlds."
