I disagree with pg about the use of philosophy. If nothing else, Plato should disabuse anyone of the notion that what's obvious to them isn't really that solid

I disagree with pg about the use of philosophy. If nothing else, Plato should disabuse anyone of the notion that what's obvious to them isn't really that solid. Aristotle at least demonstrates your point about just how hard it is to think systematically about this stuff. The humility gained from those encounters would do a great deal to open people's minds that "there's more on heaven and earth than are dreamt of in your philosophy". Maybe people would less adamant, and pay more attention to why they hold their opinions. If everyone did that, we'd have far more productive discussions.
