Book excerpt: In Who Is the Dreamer Who Dreams the Dream? A Study of Psychic Presences, James Grotstein integrates some of his most important work of recent years in addressing fundamental questions of human psychology and spirituality. He explores two quintessential and interrelated psychoanalytic problems: the nature of the unconscious mind and the meaning and inner structure of human subjectivity. To this end, he teases apart the complex, tangled threads that constitute self-experience, delineating psychic presences and mystifying dualities, subjects with varying perspectives and functions, and objects with different, often phantasmagoric properties. Whether he is expounding on the Unconscious as a range of dimensions understandable in terms of nonlinear concepts of chaos, complexity, and emergence theory; modifying the psychoanalytic concept of psychic determinism by joining it to the concept of autochthony; comparing Melanie Klein's notion of the archaic Oedipus complex with the ancient Greek myth of the labyrinth and the Minotaur; or examining the relationship between the stories of Oedipus and Christ, Grotstein emerges as an analyst whose clinical sensibility has been profoundly deepened by his scholarly use of mythology, classical thought, and contemporary philosophy. The result is both an important synthesis of major currents of contemporary psychoanalytic thought and a moving exploration of the nature of human suffering and spirituality.
