I bought this book after having my interest sparked in Plato and Aristotle last year. I found that Cooper answered most of what my professors had simply labeled controversies, with had no real definitive answer, with remarkable ease. Cooper's work is impressive, but he is not arrogant or dogmatic. I particularly enjoyed his essays on Aristotle's conception of Friendship, Aristotle's views on contemplation, and the Greeks views on suicide and euthanasia. In general, I found the book to be absolutely necessary for anyone who has even a cursory interest in the Ancient Greeks.
