I bought this books as a reference after reading Russell’s famous books on similar subjects. I found this book is very clear in describing different schools of western philosophy and I got some new insights and understandings of a lot of difficult philosophical thinkers. Contrary to my expectations I did not need to consult the original English texts because the Chinese translation is clear and smooth enough for me to read. Hats off the the translators. Highly recommended to anyone interested in getting a quick picture of the western philosophical thinking.
