Can we consistently identify God and the Universe?

Abstract
In this essay I argue that it is reasonable to identify the god of classical theism with the universe revealed by physics. I follow variations of the cosmological form of argument for the existence of God from Aristotle’s first mover to Aquinas’ “first way”. I then propose re-interpretation of ancient terminology to suggest the consistency of physics with the idea that the universe is a purely actual, living, intelligent being similar to the ancient understanding of god. The next step is to suggest that Einstein’s general and special relativity are consistent with the present hypothesis. I then turn to quantum theory, understood as description of network computation and communication, to argue that this structure, by analogy with animal central nervous systems, justifies seeing the universe as mind, laying a foundation for panpsychism. This enables a consistent monist interpretation of reality that sees god and the universe as identical.

Does god exist: Aristotle and the cosmological argument
Aristotle argues in Book 8 of the Physics and Book 12 of the Metaphysics “that there must be an immortal, unchanging being, ultimately responsible for all wholeness and orderliness in the sensible world” (Aristotle). He applies his notions of possibility and actuality to arguing for the existence of an unmoved mover as the source of all motion in the world. He defines motion as the transition from possibility to actuality. He assumes that it is axiomatic, that no possibility can actualize itself. Something already in existence is required to realize a possible new being. If we imagine a sequence of such causes, and observe that there is motion in the world, we are led to postulate a first unmoved mover lest we be confronted with an infinite sequence of agents with no beginning. Aristotle, Metaphysics

This argument is a representative of a general line of argument for the existence of god which takes the form (1) the observable world has certain features (eg motion); (2) the world cannot of itself explain these features; so (3) there must be another explanation for these features which we will agree to call god. It is implicit in this argument that the being that terminates the explanatory regression is a necessary being which needs no explanation because its nature is to exist.

We may then ask if this god is part of the world or other than the world? The traditional theistic position, the conclusion sought by proofs for the existence of god, is that it is other than the world. The alternative assumption, consistent with Aristotle’s view, is that it is part of the world, and I shall proceed on that basis.

From the point of view of traditional theism this assumption appears to raise a host of difficulties since at first glance, the God of theism and the world of experience appear very different. A more careful analysis, however, suggests that this difference may be illusory. Recent developments in the quantum theory of information and computation (the execution of logic), suggest that matter has properties consistent with mind. From a thoroughgoing monist point of view this discovery may ground an identification of matter and spirit, eliminating the ancient theoretical distance between heaven and earth.

Aquinas and the “first way”>
In the Summa, Aquinas provides five ways to argue for the existence of God (Aquinas, I, 2, 3). “The first and more manifest way is from motion.” He closely follows Aristotle’s argument for the first unmoved mover, concluding “Therefore it is necessary to arrive at a first mover, put in motion by no other; and this everyone understands to be God.” True to his Mosaic and Christian faith, Aquinas believes this god to be other than the world. He also concludes, following Aristotle that this god is pure actuality, actus purus, since it is the realization of all possibility. Aquinas Summa I, 2, 3: Does God exist?

This characterization of God raises a question which I have not seen raised by theists. If God is the realization of all possibility, how can there be “room” for a created world other than God? If we identify God and the world, this difficulty does not arise.

Aquinas goes on to use the pure actuality of God to argue for all the other standard attributes of God, simplicity, immobility, eternity, omnipotence, omniscience and so on. Aquinas, Summa, I, 3, 7: Is God altogether simple?

Aristotle meets Galileo and Newton

Aristotle, observing instances where friction was involved, concluded that a continual application of force was needed to keep a body in motion. This ideas was rejected by Galileo and became Newton’s first law of motion: “A body at rest remains at rest and a body in motion continues its motion in a straight line unless it is acted upon by a force”. Isaac Newton: The Mathematial Priciples of Natural Philosophy

Newton modelled the action of force with his second law: “The acceleration of a body acted upon by a force varies directly as the strength of the force impressed and inversely as the mass of the body.” Together with the third law: “action and reaction are equal and opposite”, Newton was able to formulate his law of universal gravitation and show that both celestial and terrestrial bodies obeyed the same dynamics, weakening the ancient belief that the heavens are radically different from the sublunary world. Although Newton’s four laws are quite simple, their application to the gravitational dynamics of three or more bodies is mathematically intractable. This led to two important developments, the conservation of energy and the use of variational methods which made action the most important dynamical variable and paved the way for quantum mechanics and the quantum of action.

The life of God

Like Jehovah before him, the Christian God is a living God. In the Summa Aquinas faces the objection that life is defined as self motion and motion as the passage from potential to actuality so that life and motion cannot be attributed to a being of pure actuality. Aquinas resolves this objection by referring to Aristotle’s De Anima where it is noted that “intellectual” motion (as in God) proceeds not from potency to actuality but from actuality to actuality. Aristotle De Anima: 431a6

Aristotle’s argument for the unmoved mover sees motion as proceeding from potential to actuality, subject to the axiom that no potential can actualize itself. The conservation of energy was not understood until it was realized that energy comes in two forms, potential and kinetic. We might identify these physical terms with Aristotle’s metaphysical potentiality and actuality. The difference, in post newtonian physics, is that potential and kinetic energy are equivalent, as we see in a frictionless pendulum which unceasingly converts its energy from potential to kinetic and back again. Here Aristotle’s axiom does not apply, and we may see the life and motion of the universe, as exemplified by the pendulum, as intellectual motion, from actuality to actuality. I suggest that the equivalence of kinetic and potential energy provides a bridge between the traditional theology of the living God and the physical dynamics which we observe from our position, according to the present hypothesis, “inside” God. This is consistent with the panpsychist interpretation of quantum mechanics discussed below.

General relativity: god and the initial singularity

We may argue: (1) God has four attributes: existence, eternity, absolute simplicity and creation. (2) The initial singularity, predicted by the general theory of relativity has the same four properties. So (3) we may identify God and the initial singularity.

(1) is to commonly agreed by theists.

(2) The theory of general relativity was published by Einstein in 1916 (Einstein 1916). Since then its major predictions have been verified and it is generally considered to be the standard model of the large scale structure of the universe. It is in everyday use for precision celestial navigation and global positioning systems. The mathematical work to extract the predictions of the initial singularity and black holes from the theory was published in 1975. The authors write:

Einstein's General Theory of Relativity . . . leads to two remarkable predictions about the universe: first that the final fate of massive stars is to collapse behind an event horizon to form a 'black hole' which will contain a singularity; and secondly that there is a singularity in our past which constitutes, in some sense, a beginning to our universe. Our discussion is principally aimed at developing these two results. Hawking & Ellis: The Large-Scale Structure of Space-Time

Einstein said that the “happiest thought of his life” was the realization that a freely falling person does not feel their own weight. Free fall is inertial motion, the gravity free state of motion in which Newton’s first law holds. A particle in inertial motion is said to follow a “geodesic”. The curvature of space described by general relativity causes particles on nearby geodesics accelerate toward one another even though they feel no force, a violation of Newton’s second law. A singularity is indicated by “geodesic incompleteness”, a situation where the history of a freely moving observer does not exist after (or before) a finite interval of proper time (Hawking and Ellis page 258). Proper time is time measured by a clock carried by the observer.

The existence of theoretically predicted initial singularity is supported by observational evidence, although the first 400 000 years or so of the life of the universe are invisible to us. This singularity ‘predates’ space and time. It is therefore without space-time structure, or any of the structure contained within space-time, so it is simple and eternal. It is the source of the universe. We can no more ask where it came from that we can ask where God came from. Insofar as there is are no grounds for distinguishing these two entities, it seems reasonable to identify them.

The mathematical formalism of the general theory predicts that the universe must either expand or contract. We observe that as a whole the universe is expanding, but local contractions form back holes. We may extrapolate the expansion back in time to the initial sinularity

Cosmologists understand the initial singularity to be the source of the “big bang”. This is not an explosion of stuff into existing space, but rather the creation of space-time and all that it contains. The cosmic background radiation gives us evidence back to about 400 000 years after the beginning, and evidence from high energy physics is used to extrapolate back to very close to the beginning (Hinshaw et al). Cosmological evidence for, the existence of black holes is now very strong and the recent detection of gravitational waves gives us a new window on very high energy interactions close to the beginning. Begelman: Evidence for Black Holes

Special relativity, formalism and communication

Einstein conceived the need for the special theory when he imagined himself travelling alongside a light beam. Classical mechanics predicted that the beam would appear stationary, but this contradicts Maxwell’s equations for the propagation of light. Einstein thus sought a transformation that held the velocity of light is a constant for every observer in an inertial frame, regardless of their state of motion relative to the source of the light. An observer travelling at the velocity of light, c, toward a source of light, must measure the velocity of the oncoming light as c. The Lorentz transformation explains this result, apparently paradoxical in Newtonian mechanics, that c + c = c (Lorentz transformation - Wikipedia). The special theory describes the local structure of space-time which the general theory extends to a picture of the whole universe. Maxwell's equations - Wikipedia

Except for some nuclear interactions, all communication in the universe is mediated by photons. Photons follow paths known as null geodesics whose property is that the spacetime interval between their endpoints is 0. The ‘time dilation’ and ‘length contraction’ implicit in the Lorentz transformation for a particle moving at the velocity of light show that from the point of view of an observer, the lifetime of any photon is 0 and its length is 0. This suggests that particles on null geodesics are effectively outside space and time, formally identical to the initial singularity and god. A pantheist might say the world is full of gods. Feynman: QED: The Strange Story of Light and Matter

Quantum mechanics: a step toward panpsychism?

The two theories of relativity are classical theories, built on continuous mathematics and considered to be deterministic. They describe the macroscopic behaviour of the world, but do not tell us how things actually work. This is the role of quantum mechanics, which describes the computational processes behind the scenes.

Quantum mechanics began when in 1900 when Max Planck discovered that the communications between matter and radiation occurs in finite discrete steps which have come to be called quanta of action. These steps are effectively atoms of action and are extraordinarily small by human standards. Quantization was a shock, and it remains a difficult problem in quantum theory to reconcile the continuous complex linear algebra that forms its mathematical foundation with its digital output. This is called the “measurement problem” or ‘the collapse of the wave function’. The explanation did not come until 1948 when Shannon showed that error free communication in the presence of noise could be achieved by quantizing messages. Wojciech Hubert Zurek: Quantum origin of quantum jumps: breaking of unitary symmetry induced by information transfer and the transition from quantum to classical, Claude E Shannon: A Mathematical Theory of Communication

The interpretation of the quantum mechanical formalism became clearer when Feynman and others realized that the the mathematical operators of quantum mechanics could be interpreted as logical operators, thus founding the closely related disciplines of quantum communication and quantum computation. Nielsen & Chuang: Quantum Computation and Quantum Information

Quantum field theory sees all motion as the creation and annihilation of quantum states, which we may understand as the execution of a logical function whose input is annihilated on the creation of its output, thus conforming to the conservation of energy. In the past, matter has been seen as something dead and inert the absolute antithesis of a God which is alive, intelligent and eternally active. The advent of quantum mechanics has shown us that the universe is in fact a huge network of computation and communication. By analogy of the human central nervous system, it would be quite reasonable to see the universe as mind rather than matter, an approach which removes much of the cognitive dissonance from the identification of god and the world. Zee: Quantum Field Theory in a Nutshell

Discussion:

1: The identity of god and its attributes

Traditional theology maintains that the absolute simplicity of God means that it and its attributes are identical. This remains true on the present hypothesis. The knowledge of god is encoded the structure of the universe. God is no longer outside the universe “looking in”, the universe is God's knowledge. The dynamics of the universe is God’s power; the elements of the universe like photons which are outside space-time are representatives of God’s eternity; the dynamic unity of the universe is god’s simplicity. We are inclined to think of separate entities in the universe like sheep as things, but they are better thought of as events, coupled to all the other events in the universe into a dynamically seamless whole.

2: Can theology be a science?

Medieval scholasticism defined science as a purely deductive exercise proceeding from premisses per se nota, which we would call analytic or basic. It claims theology to be a science since its premisses are allegedly revealed by a truth telling God. On the present hypothesis, God is observable and in fact all human experience is a subset of God’s experience. Scientific theology, in the accepted sense of science, is therefore possible. Since Galileo’s time all the sciences except theology have escaped from institutional and political control. As long as God is an arbitrary political creation, it will remain in captivity. By linking itself to reality, as the other sciences have done, theology can become independent. Because God and the universe are one, scientific theology can become unified like the other sciences, weakening a fertile source of political and religious conflict. Oppy & Scott: Reading Philosophy of Religion: selected texts with interactive commentary, (Plantinga pp 204 sqq), Paul Arthur Berkman: Could science diplomacy be the key to stabilizing international relations?

Conclusion

The arguments outlined here suggest that we can reasonably identify the universe revealed to us by physics with the god described by Aquinas. Aristotle laid the foundation for medieval Christian scholastic theology which is promoted by the Christian churches to this day. His arguments may be reformulated in the light of the last five hundred years of science to provide simple explanations of the traditional attributes of god such as creation and annihilation, providence, omniscience and omnipotence, and open the way for scientific, evidence based theology. Since science tracks reality, and god is one, we can expect theology to converge toward a unified view of the world as the other sciences are doing.

This hypothesis is speculative, but the political and social benefits of a scientific theology suggest that it may be worthy of being met halfway for further development.

Albert Einstein, The Field Equations of Gravitation, 'In two recently published papers I have shown how to obtain field equations of gravitation that comply with the postulate of general relativity, i.e., which in their general formulation are covariant under arbitrary substitutions of space-time variables. . . . With this, we have finally completed the general theory of relativity as a logical structure. The postulate of relativity in its most general formulation (which makes space-time coordinates into physically meaningless parameters) leads with compelling necessity to a very specific theory of gravitation that also explains the movement of the perihelion of Mercury. However, the postulate of general relativity cannot reveal to us anything new and different about the essence of the various processes in nature than what the special theory of relativity taught us already. The opinions I recently voiced here in this regard have been in error. Every physical theory that complies with the special theory of relativity can, by means of the absolute differential calculus, be integrated into the system of general relativity theory-without the latter providing any criteria about the admissibility of such physical theory.' back

I show that even imperfect copying essential in such situations restricts possible unperturbed outcomes to an orthogonal subset of all possible states of the system, thus breaking the unitary symmetry of its Hilbert space implied by the quantum superposition principle. Preferred outcome states emerge as a result. They provide framework for the ``wavepacket collapse'', designating terminal points of quantum jumps, and defining the measured observable by specifying its eigenstates. In quantum Darwinism, they are the progenitors of multiple copies spread throughout the environment -- the fittest quantum states that not only survive decoherence, but subvert it into carrying information about them -- into becoming a witness.' back
