Symbolism and Reality [PDF ebook] 
A study in the nature of mind

Charles W. Morris‘ doctoral thesis Symbolism and Reality, written in 1925 at Chicago under George H. Mead, has never before been published. It sets out to prove that thought and mind are not entities, nor even processes involving a psychical substance distinguishable from the rest of reality, but are explicable as the functioning of parts of the experience as symbols to an organism of other parts of experience. Being then the symbolic portion of experience, the psychical or mental can neither be sharply opposed to the rest of experience nor identical with the whole of experience. This edition includes a preface by Achim Eschbach, an extensive bibliography of Morris‘ works, and indices of names and subjects.
