...can't Wigner's "unreasonable effectiveness" be explained in some way via the anthropic principle? (there should be a way to reason that intelligent life like us could only have evolved in an universe where predictions about physical systems can be made considering only a small subset of the initial condition variables, and also that "abstract mathematical ideas" could only appear in someone's mind from a sort of intuition of the universe's laws, so that the mathematicians' intuition can't come "out of the void" but is actually subconsciously "inspired" by the laws of nature at some level and this is why it explains them, and that what "feels" "simple and elegant" to a mathematician actually feels this way because it's in accordance with the universal laws of nature by witch his mind also works...)
