In the first comprehensive work to articulate a psychoanalytic metaphysics based on process thought, the author uses dialectical logic to show how the nature and structure of mental life is constituted. Arguing that ego development is produced not only by consciousness but also evolves from unconscious genesis, he makes the controversial claim that an unconscious semiotics serves as the template for language and all meaning structures. A thought-provoking account of idealism, Origins confronts the limitations of materialism and empiricism while salvaging the roles of agency and freedom that have been neglected by the biological sciences.
