It's the tool for learning how to use other tools. It's the bones that give a clenched fist its structure (and knuckles). With that in mind, we have painstakingly designed Introductory Logic for everyday students, teachers, and parents who've never tackled syllogisms or fallacies before, but who know just how important learning logic is.
