Continental philosophy is a group of Western philosophies first prominent in 20th-century continental Europe that derive from a broadly Kantian tradition of focusing on the individual and society. Continental philosophy includes German idealism, phenomenology, philosophical pessimism, existentialism, hermeneutics, structuralism, post-structuralism, deconstruction, French feminism, psychoanalytic theory, posthumanism, speculative realism, and the critical theory of the Frankfurt School as well as some Freudian, Hegelian, and Western Marxist views.
