Stace's first 4 books - A Critical History of Greek Philosophy (1920), The Philosophy of Hegel: A Systematic Exposition (1924), The Meaning of Beauty (1929), and The Theory of Knowledge and Existence (1932) - were all published while he was employed by the Ceylon Civil Service.
His work in the 1930s and 40s bears a strong influence of phenomenalism, a form of radical empiricism (not to be confused with phenomenology, which examines the structure and content of consciousness) [REF].
