" Profound in-depth insight into the world of evil from a scientific (psychological)point of view. As a psychology graduate myself, I find Dr.Peck's work highly valuable. Also, he usually lays out the facts as well as his personal findings or interpretations and does not force them on the reader. He offers room for much skepticism, thus -I believe- he is a man who is truly in search of the truth! "
