Summary: A book chock full of logic
Review: "Schaum's Outlines Logic" covers more material than you can learn in a single semester course in logic. If you will select what to learn after you buy the book, include the chapter on logical fallacies. Logical fallacies are noticable in conversation and in your own thinking. You can find fallacies in newspaper articles, political speeches, and your arguments with your loved ones. My first college course in logic covered the propositional calculus, the final exam involved solving argument forms for validity. This book covers propositional calculus in a chapter, before it goes on to the predicate calculus in two following chapters. You need mathematics skills to handle the pace this book sets, chapter by chapter. You'll find it easier to follow along if you already know some logic. So stick out the earlier chapters to make it through the later chapters. A bonus final chapter gives you a peek at advanced studies in logic, if those might interest you. The book's explanations are terse. Solved problems and end-of-chapter problems help you learn the material. I don't like that only a quarter of the end-of-chapter problems have solutions you can look up. But the book was great for my needs, so I give it five stars.

Summary: A book better than Copi's thick volume
Review: Although it is thinner than Copi's, I think the author processes the tutorial in a better way, more appealing to me, at least. It is a necessary for a beginner at the gate of logic. It suffices the three standards of a good textbook: general, simple and clear. After that, you can go deeper in some specific areas.
In short, I recommend this book without reservation.

Summary: For me it was useless
Review: I bought the book on the good reviews. I am taking a college level course in logic for which we are doing first order logic, not predicate logic. After looking in the index for topics from the class text and not finding the first six topics I needed, I gave up. Plus nothing in the book is similar in anyway to what I'm doing. If you need a book for predicate logic, it looks to be very good for that. If you need a book for first order logic, look elsewhere.

Summary: Excellent book for the price
Review: I have purchased quite a number of Schaum's Outline books. Most of those books give the reader the sense of being rushed. The material isn't always comprehensive or is so abbreviated as to be incomprehensible. On the other hand, this particular outline on Logic is not merely an outline but serves extremely well as a standalone textbook. In fact,it covers in great detail most of the topics it discusses. The examples and explanations of the topics were very easy to understand, and the structure of the books is very logical. I heartily recommend this book.

Summary: excellent intro to logic for anyone
Review: If you are learning logic for the first time, either as a non-mathematician or as an engineer, then this is an excellent place to start. The book covers propositional calculus, predicate calculus, induction, and of interest to computer science majors with an interest in automated reasoning, it covers refutation trees and probability calculus. The book does have a peculiar approach to predicate calculus that it does not include functions when it first covers predicate calculus. Functions are introduced in a later chapter. A very interesting chapter covers fallacious forms of argument. Overall, an excellent introduction to logic.

Summary: The best intro. to Logic book around
Review: If you only study one logic book, this Schaum's outline should be the one. This book makes clear what other books leave fuzzy and unclear. And its price is a fraction that of other books! If, after studying this Schaum's book, you want to go deeper into sentential logic, then study "Intro. to Logic" by Copi. If you want to understand the more informal use of logic in mathematical proofs, then I recommend studying Schaum's first, and then "How to Prove It", by Daniel Velleman.

Summary: Excellent value, well written, a bit old fashioned.
Review: The good news. This book is excellent value for the money, and is the best written Schaum's Outline I have ever read. It is certainly not excessively mathematical, compared to nearly everything that passes for logic nowadays. Schaum's outlines are seldom written by first-raters in their respective fields. This is a clear exception; Varzi is a first rate contemporary philosopher. This book is an excellent example of modern scientific communication. The bad news. The book's approach to logic is a bit on the old fashioned side. Much of the material on traditional logic could have been omitted. The book shares a flaw that is sadly all too common: trivial propositions take 20-40 lines to prove. The refutation tree or natural deduction machinery of this and other contemporary books is far too ponderous. This book, like all too many books in the philosophical logic tradition, devotes time to topics that leave me cold, such as modal logic. Meanwhile, it slights or omits topics that fascinate me, such as mereology, the isomorphism between truth functors and Boolean algebra, and metatheory. I like probability and inductive logic and feel that these have a great deal to offer to logic and philosophy, but this book only scratches the surface of these topics. The main comsumers of logic nowadays are computer scientists. It is not at all clear that this book would be of any value to them. On the other hand, this is an excellent book for your typical philosophy major.

Summary: excellent introduction to the mechanics of logic
Review: This book is an excellent introduction to what I call the
mechanics of logic. If you are interested in metalogic
proofs, like the deduction theorem, then don't look here.
This book teaches the basics of logic. It presents logic
in several different ways: using Aristole's version (strictly
for historical reasons), using Venn diagrams, a Hilbert-style
logic (rules to introduce and remove boolean operators), and
semantic tableaux. Also, it first introduces propositional
logic, then it proceeds to predicate logic. The book has
a peculiar approach that it does not introduce functions (not
predicate functions) until much later. One of the more interesting chapter covers fallacious arguments.

Summary: By far the best logic textbook
Review: This is by far the best textbook that I have seen. It's clear and detailed, and full of solved exercises which help the reader verify their understanding of the material. Too bad the cover suggests it's cheap, because it is really a thorough introduction to logic. You'll love it for sure. (To the reader from Miami: First-order logic is the same thing as predicate logic, so what you were looking for IS in this book!)
