Language Proof and Logic is available as a physical book with the software included on CD and as a downloadable package of software plus the book in PDF format. The all-electronic version is available from Openproof at ggweb.stanford.edu.The textbook/software package covers first-order language in a method appropriate for first and second courses in logic. An on-line grading services instantly grades solutions to hundred of computer exercises. It is designed to be used by philosophy instructors teaching a logic course to undergraduates in philosophy, computer science, mathematics, and linguistics.Introductory material is presented in a systematic and accessible fashion. Advanced chapters include proofs of soundness and completeness for propositional and predicate logic, as well as an accessible sketch of Godel's first incompleteness theorem. The book is appropriate for a wide range of courses, from first logic courses for undergraduates (philosophy, mathematics, and computer science) to a first graduate logic course.The software package includes four programs:Tarski's World 5.0, a new version of the popular program that teaches the basic first-order language and its semantics;Fitch, a natural deduction proof environment for giving and checking first-order proofs;Boole, a program that facilitates the construction and checking of truth tables and related notions (tautology, tautological consequence, etc.);Submit, a program that allows students to submit exercises done with the above programs to the Grade Grinder, the automatic grading service.Grade reports are returned to the student and, if requested, to the student's instructor, eliminating the need for tedious checking of homework. All programs are available for Windows, Macintosh and Linux systems. Instructors do not need to use the programs themselves in order to be able to take advantage of their pedagogical value. More about the software can be found at lpl.stanford.edu.The price of a new text/software package includes one Registration ID, which must be used each time work is submitted to the grading service. Once activated, the Registration ID is not transferable.

I was recommended this recently book while visiting my old Philosophy Advisor while in Boston. I've been hooked ever since! While for me it has been a great review of logic, the problems and ability to have them anonymously graded on the net is great fun! At the end of chapter 3 one is already versed well enough in logic to use the more complicated search engines with boolean operators. (altavista advanced for example). Being able to use sophisticated search engines will prove to be more and more valuable..
Overall, this is not a bad book. In fact, I can see how it can be quite helpful for some. However, I must admit I'm not impressed by this book and would certainly not use it to teach a logic class.Pro:This book provides generous background information and explanation to the terms, concepts, rules, methods, etc. contained within. It also comes with a CD-Rom with helpufl information that guides you through the learning process. With this book, it is possible to submit your work to the "gradegrinder" grading s..
I bought a used copy of the book and software at the beginning of the term, for a class. Now that we're starting it, I find out that a) we will be using the CD's software, including the online grading service, and therefore b) the copy I bought is useless to me.
