You cannot possibly gain new knowledge about physics by doing moral philosophy.
This seems untrue. If you have high credence in the two premisses:
If X were a correct physical theory, then Y.
Not Y.
then that should decrease your credence in X. It doesn’t matter whether Y is a proposition about the behaviour of gases or about moral philosophy (although the implication is likely to be weaker in the latter case).
