A fascinating series of lectures given at the university of St. Andrews in 1922. The lectures cover the topics of mental and no-mental emergence, relatedness, reference, memory, images, towards, reality and causation and causality. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
