Book excerpt: In addition to his influential scholarship on economic and social theory, F. A. Hayek greatly impacted theoretical psychology with his book "The Sensory Order." Perhaps because he was a social scientist, Hayek s work in psychology has been mostly overlooked. Editor Viktor Vanberg frames "The Sensory Order" as an essential work necessary for any deeper understanding of Hayek s economic and social philosophy while adding on several important essays by Hayek that help illuminate the ideas of the book since its original publication in 1952. As volume 14 of the Collected Works of F. A. Hayek, "The Sensory Order "will definitively take its place as an integral and foundational part of Hayek s oeuvre."
