Reddit mentions of A Concise Introduction to Logic

I wasn't taught it until recently, when I got into philosophy at uni. The way I've learnt it (and the way most tend to) is through studying logic. Stanford encyclopedia of philosophy has a good page on informal logic here.

If you want to learn more about logic itself, I would recommend reading into it with the relevant texbooks, such as Patrick J Hurley's concise introduction to logic or Samuel Guttenplan's The Languages of Logic. I would highly recommend the first, over the second. If you can't buy the books, there's a good series on formal logic here that I've gone through, before.

It can be a hard thing to learn, but it is extremely rewarding. Logic gets you to think with better clarity, deconstruct ideas better and make stronger arguments. Best of luck!

I learned logic from 'A concise introduction to Logic.' by hurley

Do you have some idea of the type of logic you want to learn? an introduction into modern logic usually encompases two aspects: propositional (sentential) and predicate (first-order) logic. Once you learn these, you can learn other types of fun logic like metalogic, modal logic, and maybe even set theory. There's also Aristotelian logic (i.e. syllogisms and the square of opposition.) I learned this, but i never use it so i wouldn't recommend learning it (although the text i provided has chapters on both)

Overall, I think it's a great text and you can easily learn everything in the book on your own without a teacher. The book's pricey, but it's worth it if you're serious about learning Logic. I still use it whenever i want to learn what a specific term is called, remember a rule of inference, predicate logic restriction, etc.

i've found that this is a pretty good resource if you want a written introduction online:

I'm using this book for a second logic course in an undergrad philosophy program, and even though it's in its 5th edition, it's full of typos—in the text, in the exercises, and in the answers (downloadable from the publisher's web site). I'm compiling a list to submit at the end of the semester. The quality control is just terrible.

Also, I take to logic easily, so I learn the material despite the book. But I'm helping some of my friends study, and its teaching method is doing them no favors.

The textbook we used for the first course, Hurley's A Concise Introduction to Logic, was much better, but it won't cover the advanced material OP is interested in.
