My only criticism of the book is also one of its chief virtues, that is, it lacks statistical tables, charts, diagrams and numbers drawn from the author’s vast experience. However, such recapitulation of what is already documented in other sources is unnecessary to the mission of this book, which is to provide a useful and readable source for the profession and the public to deal with this enormous social problem. Left unexplained, although fully described, is the biological defect or perhaps adaptive flaw that produces personalities who can lie, cheat, and steal without feeling guilt. In The Inferno of Dante, Ulysses is in the eighth circle of hell, which is a place reserved for con men, where he has been placed for deceiving his crew on his self-serving search for adventure or what Cloninger would describe as sensation-seeking behavior. Ulysses illustrates the paradox of antisocial personality disorder by his speech to his men, who were misused for his own purposes, with the deceit, "You are not born to live as a mere brute does, but for the pursuit of the knowledge and the good" (8, Canto 227). Thus, the paradox of human nature is that knowing what is right and good and claiming to have been reformed, mankind continues to lie, cheat, steal, and make war to its own detriment and to the consternation and misery of others.
