Learn, understand, then decide whether you accept or reject.
Don't let the fact that this is the shortest one of the Great Courses discourage you from picking it up. It's worth listening to more than once, and its length encourages it.
This is a concise, educational and interesting buy. I was familiar with the Art of War, but the Professor, who has plenty of experience in the US military and a passion for the Art of War, quickly delivers the facts with efficient, no-nonsense lectures that keep you interested.
With the exception of a single lecture about Islam, this course focuses on European and American philosophy. While it is good and detailed about Western philosophy, I was hoping for an all-encompassing look at global philosophy.
I listened to this right after its Western counterpart, and immediately noticed a lot of parallels (debates on the meaning of life) and deviance (emphasis on spirituality until very recently.) There is a lot of concentrated wisdom in this course from China, Japan, India and (in a single lecture) Korea. I was disappointed at the complete absence of Russia in this course, however.
