I took a critical thinking class over the last semester and we did some work with truth tables, but it was by no means a mathematical logic class. However, if you’re as into philosophy as it seems, I think you’ll like the class – just drink coffee when you wake up haha. It’s probably worth noting that as a philosophy major myself, I’ve found the difficulty of philosophy teachers on ratemyprofessor to be somewhat misleading. If you’re into a specific class/major you’re gonna have a much easier time doing the work than others who are dreadfully attempting it without any interest/curiosity present, and I think many of the negative ratings on ratemyprofessor come from students who were not interested in/curious about the course material.
Symbolic logic actually sounds pretty cool. There’s a lot of logic/reasoning buried within language that we are often unaware of, and logic classes help bring those aspects of human language up to the surface at a comprehendible level.
