And the same can be directed at philosophy far more pointedly because .....drum roll drum roll drum roll...logic is the cornerstone of philosophy.
But without a way to pit its ideas and conclusions against reality, it's logic might be valid but unsound, to only name a single possible issue. That "logic" is part of the deal doesn't mean it's right, or better, or whatever.
But every time we try to prod to find out exactly in what way it answers questions, for some reason it becomes either words games or semantics.
