Meditation:

If we can only meaningfully talk about parts of the universe that can be pinned down inside the causal graph, where do we find the fact that 2 + 2 = 4? Or did I just make a meaningless noise, there? Or if you claim that "2 + 2 = 4" isn't meaningful or true, then what alternate property does the sentence "2 + 2 = 4" have which makes it so much more useful than the sentence "2 + 2 = 3"?

While it seems viable to say that mathematical truths exert causal (albeit time-invariant) influence on the universe, you might think it prima facie unlikely that we could causally influence them. However, it perhaps we can causally affect the outputs of decision algorithms.
