Any 'dictionary' like this is only as good as its contributors, and for the most part, the contributors to The Cambridge Dictionary of Philosophy are well enough versed in their field to be able to give clear, concise synopses of the topics addressed. That's not to say that the dictionary does not have its more obtuse passages, where--either because the material is simply not able to be made more digestible or because the writer is unable to make it so--things get dense, and the purpose of a dictionary like this--to make a thinker or idea quickly accessible to the novice who has stumbled upon them (usually in some tangential capacity) in their own work--is thwarted. Unfortunately (for someone like me who works in modern theology), the time-period most commonly left complicated by this dictionary is modernity. If you're interested in post-Cartesian philosophy, it might be worth checking out a few other options. But if you're confident in your reading and abstract thinking abilities, this is an otherwise fine, mostly comprehensive work.
