Dr. Shaw simplifies the philosophical enterprise, often using helpful real life analogies to clarify the dizzying array of abstract terms that characterize philosophic endeavor. But it is still challenging to delineate the subtle nuances of the terms. That this book is written in 1929 is irrelevant, as philosophy is not science, and the meaning of life and existence and the nature of space, time, and things, is not limited to bare empirical fact, though they play a part. The discovery of relativity had occurred by 1929, and enters into the discussion. Of course, he surely had his own views which would somewhat prejudice his presentation, but he clearly makes an effort to present the various approaches thoroughly. The book certainly gave me a better handle on what philosophy is and consists of.
