An excellent account of the subject matter. Superb presentation and very rigorous indeed.

In my opinion Warren's book - contrary to the above - is an intriguing and expansive treatment of Epicurus' moral theory. To dismiss Warren's conclusion so out of hand suggests to my mind misunderstanding more than anything else. Democritus seen as a model for Epicurus is in fact a hypothesis which is well substantiated, lucid and an exciting new angle on this topic.
I recommend this book unreservedly.
