Through an integrated multi-disciplinary theory, Michael Robbins proposes that the human mind consists of two mental structures, the one we share with other animate creatures, and a capacity for reflective representational thought which is unique.

Michael Robbins is a psychoanalyst, member of the American and International Psychoanalytic Societies, former professor of Clinical Psychiatry at Harvard Medical School, and author of 5 previous books and more than 40 articles in refereed journals.
