I'm disputing something very specific. I'm not disputing that empirical reasoning is rational. What I'm disputing is that empirical reasoning is justified by empirical reasoning. This not being circular is not logically related to actual reality. Like, I'm just saying that this doesn't make sense:
1: If you try to pick a fight with reality, reality will win. (Empirical reasoning is evolutionary useful, etc.)
2: Thus, empirical reasoning is justified by empirical reasoning.
2 doesn't follow from 1. I accept 1, and I accept the rationality of empirical reasoning, but I don't accept 2.
