Title: Not a very good book!
Review: Devlin's book is really superficial.For example, it is difficult to believe that anybody can write something like this:"This rule of deduction is still known today by its original Greek name, 'modus ponens' " (35).'Modus ponens' cannot be its original Greek name, for it is Latin.In fact the rule was named as such in the Middle Ages.I suspect that Devlin cannot tell the difference between Latin and Greek.
