William Christopher Barrett (1913 – 1992) was a professor of philosophy at New York University from 1950 to 1979. Precociously, he began post-secondary studies at the City College of New York when 15 years old. He received his PhD at Columbia University. He was an editor of Partisan Review and later the literary critic of The Atlantic Monthly magazine. He was well-known for writing philosophical works for nonexperts. Perhaps the best known among these were Irrational Man: A Study in Existential Philosophy and The Illusion of Technique , which remain in print.
I read this book many years ago. It influenced my view of literary criticism through the filter of existential nihilism and 20th century aesthetic philosophy.
