>>24517376 (OP)No, Russell, for whatever strengths and merits he had as a mathematician and logician, was not a scholar of philosophers, excepting Leibniz (his book on Leibniz is very good). He wrote this to frankly make money, and, while written in an engaging and witty way, it's clearly Russell just sharing his opinions and musings over quick and sometimes very partial readings. One gets the impression sometimes that he didn't read some of the philosophers he discusses, but rather encyclopedia or textbook summaries.
A stronger alternative is Copleston. Copleston, while a Catholic, makes a valiant effort to give each thinker their due. His work is split into multiple volumes, so one way to use him is to select a volume for whatever period you're interested in.
