Reddit mentions of The Logic Book

My symbolic logic course used The Logic Book by Bergmann, Moor, and Nelson. It was a solid introduction to formal logic. I've found the knowledge to be useful across a wide variety of disciplines.

The Logic Book is a good text for FOL and the early theorems of meta-logic (soundness and completeness of propositional and first-order logics). It's somewhat slow going though.

A more mathematically inclined text is Herbert Enderton's Introduction to Mathematical Logic. Enderton goes into more of the meta-logic, including incompleteness, Lowenheim-Skolem, and computability. He also touches on second-order logic toward the end.

Along the lines of meta-logic, Boolos and Jeffrey's Computability and Logic is very good as well. (Er, and Burgess. I can only vouch for the 3rd edition, which is pre-Burgess.)

Given that you're already familiar with FOL, I'd lean toward Enderton or Boolos and Jeffrey with the caveat that The Logic Book has endless practice problems and, iirc, answers to many of them in the back of the book (the others have fewer (but more interesting) problems).

If you want to go beyond FOL, I second stoic9's suggestion of Priest's book.

Please read this and educate yourself. You are making yourself look like a fool.

Perhaps after studying and educating yourself, you may see how your statements are in error. I would advise you stop throwing around "logical fallacies" everywhere. It makes you look like a fool, it is elitist and highly cringe-worthy. I used to be like you, but I acquired an education in philosophy (Kant is my main area of research, as is the philosophy of mind), and realized how foolish I had been. You're the embodiment of /r/atheism, grasping at the straws by (wrongly) insinuating the other person has committed logical fallacies by naming fancy ones- is at best cringe worthy. You are like a child who has been proven wrong by a professor who cannot accept his defeat, so he resorts to nit picking fictitious fallacies. It's funny how you must think you are a superb armchair internet intellectual, looking about a list of logical fallacies to use as your main driving point in arguments. I too, felt euphoric whenever I thought someone else committed a logical fallacy by going "ah ha! What you've just stated is a FALLACY! What now?" but I was young and foolish. This is epistemic poverty. I urge you to at least skim through the books I have suggested or any other logic book. They helped me immensely during my undergrad and grad years. I would recommend developing a strong background in logic and epistemology (mainly the JTB account and the Gettier Response to it). After having done that and you no longer want to grasp at the straws and act like a child, I will be more than willing to help.

This is a good place to start: http://www.amazon.com/Logic-Book-Merrie-Bergmann/dp/007353563X/ref=pd_sim_b_2

I believe that this is the standard for Logic classes. It's the one I have, and you can find a solutions guide online to check your answers. It's a tad bit expensive, unfortunately!

I am a fan of The Logic Book
