In the beginning section covering Aristotelian logic, Geisler tried to hastily cover in about 40 pages, what other textbooks took over a 100 pages to explain. Geisler just dumped out multitudes of terms and concepts that left me frustratingly confused. I had to turn elsewhere to actually learn it all. Even after getting a grasp of deduction from other introductory text, I still found, in returning to Geisler, his writing to be convoluted. Over all this is a simply terrible introduction to logic. ...more

For a person who has grown up in the television age and not used to rational thinking (90% of America), this book is pivotal for an understanding of logic. Upon first glance this book is hard to read because we are not used to thinking in terms of complex propositions. And, like any textbook, the more that you put into it, the more you will get out. An understanding of loigc is necessary for even a superficial reading of the Bible. St. Paul in every sentence is using logic to its deadly effect. ...more

I honestly did not know what to expect when I opened this book. It claims to be a christian book that could be used in a course on Introduction to Logic - that is, a christian logic textbook. It is just that. No book is perfect, and this one has its share of failures. However, It covers most of the important aspects that would be needed in an introduction to logic, and then some. Many of the examples come from the Bible, or theological debate. Each chapter is followed by a number of exercises th ...more

Great book to begin to study logic. But anyone and everyone can read this. Some ideas may take some time to really soak in; but a re-reading of the paragraphs or chapters is really worth it. After all, Christians use logic, need to be logical, and should be so in talking about their beliefs as well as in conversation on any topic. This book really brings it home in helping us to understand why we believe the things we say we do and better helps us to share with others logically what views that a ...more

For me, this was a good "refresher" course on Logic - and even better to get it in a Christian Apologetic framework.

There would be much benefit if more Christians were to come to understand the mechanics behind "reasoning", thus they would be able to put forward better arguments - I direct this at myself as well. Even though I have a Mathematical background, it is easy to get caught up in the emotional side of things and to make many of the "fallacies" explained in this book.

Having not studied formal logic before this book I was in over my head. Still, I advise one dive right it. It is clear enough if one takes the time to study the material and not merely read it.

It's a book to open the mind to the extensive possibilities of honorable debate. One, by Gods grace, will close the back cover determined to not only combats errant views but the errant arguments for his own views.

For those who aren't familiar with the study of logic, this is a good primer to start that endeavor. He discusses the proper and improper construction of logical argumentation as well as the basic laws of logic and their fallacies. There were some things in this book that it could have done without (such as the co-authors attempt to be humorous). Other than that and whether or not you agree with Geisler's theological stances, it would be beneficial to give this a read.
Geisler does a great job at making logic a lot easier to understand. The examples are all from the bible,theology and apologetics because it was written with Christians in mind. This book only goes into the very basics of logic. If you came onto the book thinking that there was going to be modal logic,predicate logic or any other more advanced topics in logic then you will be very disappointed. This book is a starting point and from this book you can move up the ladder to other logic texts.

As an introduction to logic, this is an excellent book. Reading each chapter carefully and doing the exercises after each chapter gave me a better understanding of logic, so I can tackle a more in depth material.
Feb 27, 2012 rated it liked it
A good introduction to semi-formal logic. Somewhat disconcerting in it's opening thesis which suggests a reading of John chapter one which reads, "In the beginning was the Logic." Nonetheless a good read for those wishing to encounter a Christian understanding of largely Platonic logic.
