I would like to see added to every educational curriculum a course in how to think. I imagine that in olden days the study of philosophy filled that bill, however irrelevant or misguided many of the philosophies might themselves be. But we all tend to assume that logical thinking's a natural function like breathing and excreting; in reality, it's something that has to be learned . . . and many of us never in fact learn it, being able to "get by" without doing so.
