 Fingarette's work deals with issues in philosophy of mind, psychology, ethics, law, and Chinese philosophy.In his 1969 monograph "Self-Deception", Fingarette presents an account of the titular concept influenced by the work of Jean-Paul Sartre, Sören Kierkegaard and Sigmund Freud, as well as contemporary work in physiology and analytic philosophy.Fingarette argues that traditional accounts of self-deception fall invariably into paradox because these accounts see self-deception in terms of perception or knowledge.
