Offering the first comprehensive examination of Hegel's theory of the unconscious abyss, Jon Mills rectifies a much neglected area of Hegel scholarship. Mills shows that the unconscious is the foundation for conscious and self-conscious life and is responsible for the normative and pathological forces that fuel psychic development. In addition, Mills illustrates how Hegel's idea of the unconscious abyss transcends his time and is a pivotal concept to his entire philosophical system—one that advances the current understanding of the psychoanalytic mind.
