Yeah, that’s what Dawkins says. I’d agree that theists in 2019 are less intellectually responsible than naturalists (especially what I’d call the exoteric theists). But I’m not sure the point about simplicity helps much. In some ways, the micro world is far more complex than the macro one of our daily experience. Things get very complicated at the quantum level, and the regularities we experience at the level of tables and chairs are child’s play by comparison, perhaps even epiphenomenal or otherwise illusory (as Eastern traditions often have it).
But by “complex” you mean to say tables and chairs metaphysically or mereologically include all the lower levels, whereas quantum events necessarily include fewer of them. The point I was trying to make in this article, though, is that the naturalist never lands on the lowest level, because of methodological naturalism, so it seems to be turtles all the way down. In that case, the appeal to greater simplicity at the “lower” ontological levels is vacuous. There are no such levels, because the naturalist always finds herself digging deeper.
