"[In this book] believers in the value of reasoning will find themselves in very hospitable territory, where they will have the pleasure on confronting ideas that are defined with argument, and to which, should they on occasion disagree with one or the other of them, they will always feel that nothing less than a carefully reasoned response is called for. And that is the highest praise that I can think of for its author. Like Socrates, he is in love with reason; and like Socrates, he finds that other lovers of reason sense a kindred spirit and engage." Thomas M. Robinson, University of Toronto.
