This is Mortimer J. Adler's 1937 study, "What Man Has Made of Man." Within it, he explores consequences of Platonism and Positivism in psychology. This fascinating book is highly recommended for students of psychology, and it is not to be missed by fans and collectors of Adler's seminal work. Mortimer Jerome Adler (1902 - 2001) was an American educator, philosopher, and popular author. He is most famous for his work as a philosopher within the Aristotelian and Thomistic traditions. Other notable works by this author include: "Aristotle for Everybody: Difficult Thought Made Easy" (1978), "The Conditions of Philosophy" (1965), and "How to Mark a Book" (1941). Many vintage books such as this are becoming increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in a modern, high-quality edition complete with the original text and artwork.
