ating without the right help, but knowing how to think logically isn't just for "experts." Logic should be your secret weapon. 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 Intermediate Logic for everyday students, teachers, and parents who've never used truth tables or formal proofs of validity to work with syllogisms, but who know just how important and applicable learning logic is.
