Existentialism: An Introduction is a unique and contemporary textbook that goes beyond the traditional treatment of this important philosophical movement. Aiming to offer a more diverse understanding of existential thought this textbook asks questions such as, what is existence? What does it mean to be human? Can existence be justified? What is mental illness in existential terms? What is reality? by examining existential thought throughout history in Europe, Africa, Asia and the Americas. Features such as chapter summaries, further reading, examples and a comprehensive glossary make this the ideal textbook for students approaching the topic of existentialism for the first time.
