There’s something wrong with me. I stayed up late last night starting to read the textbook to Philosophy 160A, A Mathematical Introduction to Logic, by Enderton. Now that I’m more skilled in formal logic, I decided to try and go through the book again and see if I could understand it this time. Not just read through it, but thoroughly understand every statement, every example.
It took me more than an hour to get through part of chapter zero, an introduction to set theory, just a few pages. I was actually impressed by my progress.
