...I feel Martyn Oliver provided a fair assessment of N. in History of Philosophy, which is why I bought it in the first place. I recommend History of Philosophy as a fun reference guide for the layperson to further his or her interests or for someone who has a beginning interest in philosophy and doesn't know where to start or what philosophies might interest him/her.
Other recommendations: Will Durant's The Story of Philosophy, T.Z. Lavine's From Socrates to Sartre, Hilary Lawson's Reflexivity, Albert Camus' The Rebel.
