In the end, one is of course perfectly free to believe in the, so to speak, “just-there-ness” of the quantum order and of the physical laws governing it. I tend to see this as bordering upon a belief in magic, but that may be mere prejudice. What is absolutely certain is that the naturalist view of things is, as I have said, just a picture of the world, not a truth about the world that we can know, nor even a conviction that rests upon a secure rational foundation. The picture that naturalism gives us, at least at present, is twofold. On the one hand, the cosmos of space and time is a purely mechanistic reality that, if we are to be perfectly consistent, we must see as utterly deterministic: that is to say, to work a small variation on Laplace’s fantasy, if we could know the entire history of the physical events that compose the universe, from that first inflationary instant to the present, including the course of every particle, we would know also the ineluctable necessity of everything that led to and follows from the present; even what we take to be free acts of the will would be revealed as the inevitable results of physical forces reaching all the way back to the beginning of all things. On the other hand, this deterministic machine floats upon a quantum flux of ceaseless spontaneity and infinite indeterminacy. Together, these two orders close reality within a dialectical totality—a perfect union of destiny and chance, absolute determinism and pure fortuity—hermetically sealed against all transcendence. And yet, once again, the picture is radically incomplete, not only because it is unlikely that the classical Newtonian universe and the universe of quantum theory can be fitted together so seamlessly, but because neither level of reality explains the existence of the other, or of itself. And, also once again, nothing we know obliges us to find this picture more convincing than one in which higher causes (among which we might, for instance, include free will) operate upon lower, or in which all physical reality is open to a transcendent order that reveals itself in the very existence of nature.
