Jonathan Lear clearly introduces and assesses all of Freud's thought, focusing on those areas of philosophy on which Freud is acknowledged to have had a lasting impact. These include the philosophy of mind, free will and determinism, rationality, the nature of the self and subjectivity, and ethics and religion. He also considers some of the deeper issues and problems Freud engaged with, brilliantly illustrating their philosophical significance: human sexuality, the unconscious, dreams, and the theory of transference. Freud is one of the most important introductions and contributions to understanding this great thinker to have been published for many years, and will be essential reading for anyone in the humanities, social sciences and beyond with an interest in Freud or philosophy.
