But the hidden assumption here is that somehow our perceptions don’t generalise to the actual goings on in the universe, when they clearly do. Our perceptions seem extremely well correlated with reality, and even when this isn’t the case for someone psychotic, the rest of us perceive that perfectly normally. I’m agnostic and obviously can’t make any statements about where things came from or why, but I’m entirely confident that I perceive my lot in life accurately enough that I don’t need any philosophical angst about it.
