This is a very useful introduction to formal logic. However, what is even better is the recognition that formal logic bears as much relation to truth as the game Risk does--none.
a most rigorous textbook of logic
Published by Thriftbooks.com User , 24 years ago
There are so many textbooks of logic. It's just one of them. And it seems that it becomes (or has already become) out of date. But it has still the virtues that the author promised in its introduction. If we expect strictness and rigidity in the field of logic, it's the best textbook of that kind. It is mainly written from the point of the natural deduction, but it doesn't forget the axiomatic method. It first deals with the propositional logic, and second, the first-order logic. And it contains some features of metalogics and the brief history of logic. It shows all the range of the real "Elemetary Logic" as its title says.It is a standard (too standard, it maybe the only fault it has) textbook of logic. Of course, it doesn't deal with the informal or inductive logic. You need another book on that. But if you read this book with "The Computability and Logic" by Boolos and Jefferey, you would have already entered deep in this field of the formal logic. It's a good start. Although too hard or standard for lots of student, it's worth trying for.
