The Logic Manual

Fantastic help for daughter who struggles with maths.

The book is brilliantly explanatory and thus, extremely helpful.

We could all use a class in logic.

I bought this book at the same time as I bought Wilfrid Hodges's Logic. I struggled with Hodges, and turned to this present volume for assistance but had to give up on page 9. I read a couple of simpler books ( Siu-Fan Lee's "Logic", Graham Priest's "Logic - A Very Short Introduction") before going back to Hodges. Having completed that, I can now understand this book. It's as dry as dust but this in a way makes it quite attractive (there aren't many laughs in Aristotle either) and the book itself is very high quality production that is a pleasure to handle and to read.

This book is extremely analytical and at times hard to read. It is probably essential reading for budding philosophers though.

The material is well-presented for a student with little to no background in logic or set theory. However, the order is jumbled - semantics are studied before Natural Deduction, which leads one to the counter-intuitive position of having studied counterexamples to claims before proofs. With a reworked order, the book could be formidable.

A clear introduction to the study of formal logic - including the systems of propositional and predicate logic (with identity) and the natural deduction system of proof. This book is the current set text for those studying the subject at Oxford where the author is the lecturer in this field. Very suitable for those who need a high level entry into the subject, not at all recommended for someone who is looking for a light holiday read!

I was looking an introductory text to logic and stumbled across this one. It provided a detailed, yet clear and easy to understand, introduction to propositional, predicate and predicate logic with identity. It came with additional material such as exercises, lecture slides and a sample paper - all found online.If you want an introduction to logic, then this one is good.

This book and Copi's Introduction to logic are the perfect "starter pack" for logic.

Warning: This book contains logic. Not recommended for Republicans.

Clear, concise introduction to Modern Logic. It is based on Natural Deduction metods for the proofs. And it is -also- a very cheap edition.

excellent livre de référence en logique, avec les bases de la logique propositionnelle et prédicative. L'auteur aborde également les bases du raisonnement, arguments valides, et la théorie des ensembles.

I'm new to modern logic, and have been reading introduction-level books for about the last six months or so. The Logic Manual is one of the better ones, but perhaps not for starters; I think Tarski's  Introduction to Logic  is an excellent place to start, then Jc. Beall's Logic, and then possibly the Manual or Lemmon's intro book. I read the Manual before Lemmon and Lemmon's natural deduction proof system was a breeze, but that's mainly because the Manual's natural deduction system was less than clear until I used the associated on-line lecture notes. Those combined with the manual led to a bit of an "ah-ha" moment. Basically I think Halbach provides a bit less than full disclosure in his explanations, or is assuming some basic level of knowledge of logic of his readers. Without Tarski (at least) I would have been at a complete loss with the Manual; with Tarski and Beall (both 5 stars) I still had a bit of an issue, but only really with the natural deduction proofs.Having access to the on line materials is certainly a plus with this one, and I highly recommend it as a second or third read for those new to philosophical logic.
