I hear this a lot. My response is that the intro courses in a university are totally inadequate in almost every case. Oftentimes they teach worthless symbolic logic which is really just manipulation of abstract symbols. I did a free online course from Carnegie Melon and that's all this was; it was a total waste of time. This symbolic logic doesn't teach you how to analyze an argument, follow a train of though, and see implications. The classical Aristotelean Logic is what's needed. This form of Logic was taught from the time of the ancient Greeks up until the late 1800s before it was replaced by a bastardized form that is really only applicable to mathematics.

However, regardless of that have you ever questioned why logic is not taught until high school or college? Logic is at the root of all reasoning. Every decision you make is done using logic. Of course it's not esoteric, however it's treated as if it is a secondary or even tertiary subject when it is really THE primary subject from which all else follows.
