> R Hansen says: >>Forget a sixth grader, how exactly do you teach modus ponens to anyone? >>Again, to my analogy, how do you teach someone what a rose smells like? # You take them to a rose bush, and let them smell it, and say, "This is how roses smell". If you are unwilling to call that "teaching", you have have confused "teaching" with "telling" ... as have all too many American educators.
You are confused. Schools don't teach speaking (except for special cases) because people learn language naturally. Schools teach writing (or rhetoric even), because, though its related, it doesn't come entirely naturally. Also, quite naturally for you, you conflate the two, and interpret my broad way of speaking in the narrowest possible terms, as if I care.
People don't learn how to construct careful arguments naturally, even though its based on language. Learning to *recognize* modus ponens, as *part* of that skill, is likewise not a naturally acquired skill. Its more like writing, or constructing a simple proof whose logic is summarized by a picture. By the way, *recognizing* a rose, as distinct from another similar flower, is not a skill that comes naturally, like speaking a language. Your arguments doesn't pass the smell test.
