[.ca] Logic: A Very Short Introduction (ISBN 0192893203)

Very good, essential, compact:
This book is a perfect introduction to logic. It is short and goes straight to the point. It features intelligent examples, interesting exercises and a fresh and modern style. It may seem a little too short, but the reader interested in logic is likely to take this book just as an ispiration for buying more complex, specific and comprehensive books on the subject. Some logic dilemmas are left to the reader to interprete, the author just renounces to go in depth in their analysis. This may actually leave a bitter after-taste at the end of each chapter, but it stimulates to further readings in the field of logic and phylosophy of logic.

Save Your Money:
Save your money, this book is completely unreadable. If you're hoping (like I was) for a good introduction to this discipline, find another title because this one isn't it.

One of the Greatest Books Ever Written (seriously):
I purchased and read this book a few years ago when I saw someone reading it at a Harvard Square restaurant. I was curious because: (a) I was interested in logic, and (b) because it was in an intriguing new format called "A Very Short Introduction" (more on that later). After buying and working through this book, I came away loving almost every bit of the book. Even as the years have gone by since finishing Graham Priest's book, I still feel that it is one of the best books that I have ever read (and I've read quite a few). In fact, as the title of my review suggests, I honestly feel that 'Logic: A Very Short Introduction' is one of the greatest books ever written and that ANY intelligent and educated person -- even if they have little or no initial interest in formal logic, philosophy, or mathematics -- MUST buy and read this book. So what is this book about. In order to answer that question, I have to discuss the general format of this series of books as well the specifics of this book itself. Oxford Univ. Press' "A Very Short Introduction" format is a series of books that are designed to INTRODUCE an intellectual discipline to readers that can be considered LAYMAN in that particular subject. These books are brilliant because: (a) they are relatively short and, thus, busy people who have a vague interest in a subject can get an accessible account of it, (b) it is compact so that it can literally fit in a shirt or jacket pocket, and (c) they are INEXPENSIVE (all of them sell for under $10). I put some of the words above in bold letters because some of the other reviewers criticize Graham Priest's book for being too elementary. My response is: No duh, that's what it was INTENDED to be. If you are honestly an expert (as opposed to posing as one), then you probably should be reading another book (but as I will mention below, even experts in the relevant fields can probably get something out of this book). The content of this book is, as I suggested above, an accessible introduction to formal logic (from the fields of philosophy and, to some extent, mathematics and computer science). It covers most of the standard issues dealt with in a typical logic class PLUS it covers some advanced and/or non-traditional topics such as 'non-classical' logic (modal, multi-valued truth values, etc.) and more inductive (as opposed to deductive) issues such as probability theory and decision theory. To repeat myself, of course this is all at a basic, overview level but it's intended audience (laypeople interested in the field, busy intellectuals, people who need to review of fill in some gaps, etc.) will find this to book to be highly valuable. Another positive for this book is that Graham Priest is the author. I commend Oxford Univ. Press for choosing him to author the book. He is a very innovative (or controversial depending on your viewpoint) scholar in the field of logic. I appreciate the fact that he has a mathematical background (I think at least one of his degrees was in maths). I think that an implicit objection that some negative reviewers have, based on some of the quirky book recommendations involving religion, is that Mr. Priest is very irreligious and his biases shows up in the book. I'm not an atheist myself and I have to admit that the MINOR little bit where his (lack of) beliefs showed was a bit bothersome for me as well. However, I am enough of an intellectual to get over it and just accept the book for what it is: An excellent introduction to logic. And, to be fair to Prof. Priest, he does play devil's advocate with his own viewpoints and one can't fairly claim that he crams his personal views on his readers because he doesn't do that. So this and any other reasons offered up for trashing this book (and I'm writing this review because I love this book and hate to see the unfair bashing of a book I love) are really not reasonable at all. A truly magnificent and unique aspect of this book is that "Logic: A Very Short Introduction" has end of the chapter excercises for each chapter with SOLUTIONS to EVERY problem (available on the Oxford UP website for the book). I can't even begin to fully describe how great that is for autodidactic (self-study learners) folks. You can't really learn math (which logic falls under) without solving problems, and you can't be sure you've solved something without the solutions. Graham Priest's book addresses both of those issues. Even more rigourous and formal textbooks on logic sometimes nelgect to offer exercises and usually do not give solutions to all the problems. This aspect of the book alone makes it valuable to potential readers. What about the more advanced reader? As I've noted above, I think this book offers something for everyone who is smart and curious, including people who have some familiarity with logic. First, it's written by Graham Priest, a scholar with some interesting ideas on logic. Second, it covers some non-classical logics and inductive topics like probability -- things that even those who are familiar with logic may need either review in or a solid introduction to. Third, it offers questions with fully worked out solutions for each and every one of those problems, something that even dedicated texts on the subject often fail to do. Finally, it's cheap and handy so that, even if you don't find any of the above arguments satisfactory justification for buying this book, you can at least give it to your friends, family, or significant other just in case you feel they need to be educated about thinking logically. Bottom line: This is a solid introduction and overview of logic with some extras that one might not expect in a book such as this. IMHO, it is one of the greatest books ever written. It's cheap and compact. If you haven't bought it and read it, please do yourself a favor and do both. BTW, Oxford's VSI series has other great books. I would also recommend the books on intelligence (as in IQ) and linguistics.

Difficult but rewarding:
On this page, there are negative reviews, saying either that this book is unreadably difficult, or that it is superficial and elementary. Let me start by straightening this out. This book is an introduction. You can't expect it to be tremedously in-depth - it would leave readers new to the subject (those it is aimed at) out of their depth and render a broad overview impossible in the short space available. You can already see some are having difficulty as it is, but this is because Logic is a difficult topic. Having said this, this seems to be as lucid as it could be given the difficulty of the academic discipline. I read this book because I am considering doing Philosophy at university, and this is an area of Philosophy I am not familiar with. To be honest, it gave me some doubts. I found it hard for an introduction (compared with about 5 other volumes I've read it the same series). Having said this, the author does say there will be times where you have to stop, think and go back over text, and maybe I was being too impatient. So it gave me doubts about the subject. However, as far as the book itself is concerned, it is excellent. Priest does a magnificent job of making what, in the hands of almost anyone else, could be studiously dull, engaging. He applies logic to everyday problems, questions and scenarios and writes in an engaging style with wide use of examples. The mathematical nature of logic means it is not for everyone, but if you want an introduction, this is the book (I've heard that other so-called 'introductions' to the subject are rather difficult for the layman). It is rewarding when you do understand and master concepts, and it makes you think about different questions and go deeper into basic issues, adding a whole new dimension to philosophical thought.

A logical choice:
Graham Priest is author of several books on logic, including 'An Introduction to Non-Classical Logic' and 'Towards Non-Being: The Logic And Metaphysics Of Intentionality'. He has experience as a professor of logic at the University of Queensland in helping to determine the needs of those who are in need of logic help. This book, part of the Very Short Introductions series of Oxford University, is both an introduction and a refresher for those who have had logic before. Because of its brevity, it might be a bit too condensed for those looking for a logic course; however, used together with a larger text (Copi's logic book is the one I used in my early logic days), this VSI book provides good supplemental information and helps clarify key points. This book provides an introduction both to symbolic logic as well as linguistic logic. Issues such as probability, truth and fact statements, conditional statements, decision theory and validity are all presented in clear, concise ways. There are fourteen chapters (a lot of chapters for book with barely over 100 pages of text), and each chapter deals with a few key points summarised in a pull-quote box at the end of each chapter. There are diagrams, sentences and equations to illustrate the points in visual as well as language terms. The final chapter, 'A Little History and Some Further Reading', is a good short review of key figures and historical issues that underpin the material presented in the previous chapters. There is a helpful glossary of terms, and Priest also provides a page of logic puzzles and problems to be worked by the students, keyed to an Oxford University Press website that has the solutions to the questions. This is a good book for review of logic prior to taking tests (such as the LSAT) or graduate courses that require understanding of logical thought processes (systematic theology or philosophy). As some reviewers have noted, this is not a lock-step presentation of standard analytic logic (indeed, many of Priest's other writings have a more non-standard approach), but does provide some good insights in the overall way in which logic is structured and done.
