I first encountered Professor Gerard Casey of University College, Dublin, in 2004, when I was having a debate on economics with some pretty nasty people. Across the water he was giving a public lecture in my defense, but with one caveat: I wasn’t hardcore enough, he said. This is my kind of guy, I thought.

I’m thrilled to announce that Prof. Casey has prepared a course called “Introduction to Logic” for my Liberty Classroom. He has been teaching logic and other courses in philosophy for over 30 years. He’s an outstanding addition to our roster. Here’s his very short pitch on spotting bad arguments, and on the importance of logic.
