Query: A Good survey of Russel's Work

Grayling has achieved a good survey of Russel's Work in the realm of logic and philosophy as well as his contributions to social, moral, political and educational debates. The selling point for me is the fact that he does it with so much brevity and crispness. Without going into the gory details of his philosophical and logical ideas, Grayling still strikes a good balance and makes for some intersting reading.Highly recommended for people who'd like a quick introduction to Russel.
