It might be unrelated, but I followed the link to the critique of Bertrand Russell's history of Western Philosophy. The author claims its inaccurate, and proceeds to say anything about it but why its inaccurate. For instance, it says that the book ignores the role of Eastern Philosophy, well dah, the book is on Western philosophy. Russell is an admirer of Eastern Philosophy and has bee arguing that more of it needs to be consumed in the west (For more info, check Bertrand's The Problem of China). Then there is the claim that russell's logic lead him to believe that Rousseau led to Nazism, again no evidence of that whatsoever.

The piece was extremely unfounded, writing off at the beginning of the article because of that critique was a bad idea.
