““Science constantly furnishes us with astonishing ideas about the nature of reality. Physics tells us that there may be an infinite number of universes, of which ours is just one, and that perhaps two particles in no physical contact with one another can somehow influence each other’s properties. From evolutionary biology we learn that birds are the only living descendents of dinosaurs. Geologists reveal that, as a result of the current trajectory of the Earth’s tectonic plates, Australia will eventually collide with Alaska. Contemporary educated people have grown used to the idea that, at least where the causal structure of the world uninfluenced by human agency is concerned, our stock of“commonsense” assumptions and principles is systematically unreliable as a guide to the facts. Our everyday scale of perceptions, along both its temporal and its spatial dimensions, is simply too pinched and unrepresentative to be trusted as a direct window onto wider truths, at least about physics, geology, astronomy, microbiology, and so on.””
