Abstract
In his later work, Marcuse concerned himself with the nexus between social movements and unconscious dimensions of human nature. He understood Nature as an “ally” in the revolutionary process. In this paper, I seek to explore his insight through the concept of the “eros effect,” which I first uncovered while analyzing the global revolt of 1968. Forms of direct democracy and collective action developed by the New Left continue to define movement aspirations and structures. Although contemporary rational choice theorists cannot comprehend instinctual motivations, a different understanding is central to my conception
