jouissance occupied an interesting position in Lacan’s theorizing, as the core or nucleus of human psychology. It was a kind of Moebius strip, where feeling ascends to ecstasy and then circles back on itself, ouroborically you might say, to become a kind of primitive, material, and mute drive. Sometimes called “surplus enjoyment,” on the analogy of Marx’s surplus value, Lacan’s followers like Žižek built a whole Marxian-psychoanalytic critique of political-economy around the infusion of political structures with this substance or energy and its ability to be extracted or exploited in late capitalism.
