Q&A 15: What, Exactly, IS Gravity?

by Max Andrews


Hello Max,

My name is Chad Gross and I am the director of Truthbomb Apologetics.  Brian Auten of Apologetics315 recommended that I email you with a question that I have.

My question deals with gravity and whether or not it is immaterial.  It seems to me that gravity is not composed of matter and/or energy; therefore, it is immaterial.  However, when interacting with an unbeliever on the topic on this post and he said the following:

“Without mass there would be no gravity, right? It’s true that gravity itself isn’t made of atoms, but you must admit that the material world is more than just particles. Einstein showed that matter and energy are equivalent and can transform into each other. When I talk about something being material, therefore, I’m thinking of both matter and energy.

It’s true again that gravity might not be a form of energy, since it’s just a force. Maybe gravity arises due to the nature of space and time. But without matter, there would be no space and time. So I think it’s uncontroversial to consider the physical forces to be “material.”

When I think of things that are not material, I’m thinking of spirit, or soul. God isn’t made of matter or energy, and God would still exist even without any matter or energy, right?” 

Now, I realize gravity is not immaterial in the same way that moral judgments, mathematics, logic, etc.  Here is my reply to him:

Which Comes First, Science or Philosophy?

by Max Andrews

The Pre-Socratics were the first philosophers of science.  They were known as the sophos (the wise ones).  They were ecliplised by the British and German philosophers of science in the seventeenth century and were largely disconnected from science hence forth. Science sets the agenda, but philosophers bring philosophical reasons instead of scientific reasons.  Science answers the questions. The Pre-Socratics were the first to deal with metaphysics and did so to provide a rational philosophy.  This allowed for a rational and objective observation and the use of reason to systematize and order the content to make it coherent.

The Sophists were worldly-wise in contrast with the sophos–frustrated by the plurality of answers in the current philosophy. The Sophists were the original skeptics as evidenced in Pyrrho. They came out of the sixth century BC and broke away from religious dogma, which had never happened before.  Their methods were pragmatic and subjective–rhetorical and fashionable.  The phrase, “The One and the Many” became important.  The One (reality) had everything related to it (Many).  This is where we get Monism–the quality of oneness.  We see Monism appear later in Leibniz’s monads, which take us to a single substance and leads to atomic theory.

Ionian cosmology picked up the discourse. The poet, Hesiod, promoted a moral consistency with the gods and the Milesians used this as the next step of consistency to get to the natural order. Thales (624-546 BC) is often referred to as the first philosopher when he predicted an eclipse of the sun.  This was the first step in the evolution of metaphysical discovery. Thales’ theorem postulated that if angles A and C were the diameter of a circle then angle B was a right angle.  The world was rational and could be predicted and ordered.

Immanuel Kant’s Use of Newtonian Mechanics

by Max Andrews

Newtonian physics treated space and time as absolute inertial reference frames. Space and time was independent of all that it embraced and in that sense, absolute.  Space and time was isomorphic, and together with the particle theory of nature formed a mechanistic universe and static concepts that go along with it. Kant used Newtonian physics of space and time as intuitions.  The sensorium (reference frame) was transferred from space and time itself (or even God) to the mind of the subject.  Thus, the intellect imposes its laws upon nature and not nature upon the intellect.  Kant believed our thought imposes Newtonian concepts on our experiences.  Independent of experience our minds are organized to think about the world in the Newtonian framework.  Scientific knowledge was considered a priori knowledge of synthetic truths.[1]

This is what accounted for deductive methodology—using fixed premises and drawing one’s conclusions from these premises.  Kant believed that one could not know the Ding an Sich by pure reason.  The subject is limited to the fixed categories of the mind and one shapes the apprehensions through these categories.  Kant used these space and time intuitions as necessary. It proved inept for scientists to follow Kant’s use of Newton’s ideas as permanent features of the intellectual landscape having based their philosophy on his model of the universe.[2]

In 1865 James Clerk Maxwell had unified electricity and magnetism by developing his equations of electromagnetism.[3]  It was soon realized that these equations supported wave-like solutions in a region free of electrical charges or currents, otherwise known as vacuums.[4]  Later experiments identified light as having electromagnetic properties and Maxwell’s equations predicted that light waves should propagate at a finite speed c (about 300,000 km/s).  With his Newtonian ideas of absolute space and time firmly entrenched, most physicists thought that this speed was correct only in one special frame, absolute rest, and it was thought that electromagnetic waves were supported by an unseen medium called the ether, which is at rest in this frame.[5]

Scientific Theology and Evidentialism

by Max Andrews

I am approaching the world as a realist. (For a background of my epistemology please see: My Evidentialist Epistemology).  What I mean by this is that the external reality is how it appears to be to an observer making an epistemic inquiry, the measurements from science accurately depicts reality.  This is in contrast to instrumentalism, which suggests that our inquiry of the world, scientifically, do not accurately depict reality but as useful fictions.  An instrumentalist is more concerned about data fitting theories and predictions than with an accurate depiction of reality.

For the realist-evidentialist, the ontology of the world determines one’s epistemology.  They congruently correspond.  It is important to note the order of entailment.  Antecedently, reality determines our epistemology.  It would be illicit to reverse the term order and as Roy Bhaskar notes, it would be the epistemic fallacy.  I am not advocating a naïve realism where reality acts on the human mind without personal inquiry nor am I advocating postmodern anti-realism where one can construct whatever type of reality is desired.  I am advocating a form of critical realism.

Lorenzo Valla’s (1406-1457) interrogative (interrogatio) form of inquiry.  Valla’s mode of inquiry yield results that are entirely new, giving rise to knowledge that cannot be derived by an inferential process from what was already known.  Valla transitioned from not only using this method for historical knowledge but also applied it as “logic for scientific discovery.”[1]

Is Heisenberg a Defeater for an Evidentialist Epistemology?

by Max Andrews

(For further context on my epistemology see Einstein’s Impact on the Epistemic Method.  I would consider myself a moderate evidentialist.)

Scientific theology takes Einstein’s knowing and being and his understanding of reality as a whole and applies this method of theology in Christian theology.  If the world is indeed the creation of God, then there is an ontological ground for a theological engagement with the natural sciences.  It is not an arbitrary engagement, which regresses back to Newtonian engagement, but it is a natural dialogue, grounded in the fundamental belief that the God about whom Christian theology speaks is the same God who created the world that the natural sciences investigate.[1]

A major problem that presses my theory of knowledge is the Heisenberg Principle.  This principle states that an observer changes the current state of affairs being observed.  For instance, if I am measuring the velocity of a particle I cannot know the position of the particle and vise versa.  This is called uncertainty.  How this comes into the epistemic process is whether or not this principle is epistemic or ontic.  This uncertainty creates an epistemic limit.

If this principle is epistemic then what relationship does the nature of reality have on our epistemic faculty?  Heisenberg himself believed that this uncertainty was not merely epistemic but it was ontic. Back to the example of velocity and position, if Heisenberg’s ontic uncertainty is true then if an object that is not in an eigenstate[2] of position then the object does not have a position.  Position then becomes a potential property.  When the observer measures the position it is then actualized.[3]

If this principle is ontic then this may potentially be a defeater for my position.  By way of realism, there is a certain element of reality that truly is uncertain.  Causation is even worse than what Hume told us.  That is still not to say that causation does not occur, it must, but this ontic uncertainty may affect more than just the quantum world.  If all of reality is composed of particles then there is a certain extent to which properties of particle can be extrapolated to a set aggregate of particles.  It’s easy to see how this can affect evidence and meeting sufficiency for belief.  I do not believe that ontic uncertainty makes reality unknowable since, intuitively, there are some propositions that we do know to be true such as the reality and existence of the external world.  So, even if it were the case that there is an element to ontic uncertainty it would not affect my epistemic theory in a capacity that would render it void and untenable.  There may be minor nuances to my theory that would render this theory questionable but given epistemic charity or probability one may still be justified in believing any proposition that is onticly uncertain as true as long as it meets the criteria for sufficiency.

The Relationship Between Science and Philosophy

by Max Andrews

How far can science take us and at what point does philosophy and metaphysics take over?  Here is the general process of science and philosophy.

  1. METHOD. Science’s modus operandi is to observe the data while philosophy is examining the data and reasoning through it.
  2. MATERIAL. Science’s materials are facts. There are certain data that provide empirical fact to work with.  Philosophy’s material are conceptual–concepts that are the basis for the rest of the process.
  3. PURPOSE. Science is descriptive.  Empirical investigation can only observe what happens and the purpose of it is to describe the mechanism or process taking place.  The purpose, in relation to philosophy, is to be able to construct an argument.
  4. GOAL.  The goal of science is prediction.  We will see this in the strength of a theory by principle of verification and falsification.  The philosophical role is providing an explanation of the data.  Explanation is philosophical and not scientific.
  5. OUTCOME. The end of science is the production of technology. The general history of science runs in the direction of greater efficiency in its function.  Likewise, in the history of science, philosophy’s outcome is developing a worldview system.  Consider the historical development of science with Copernicus, Galileo, and Newton.  Copernicus changed the worldview system with the Copernican revolution as did Newton.  I would actually argue that Newtonian physics may have made a greater philosophical impact than Copernicus in light of Kant (thanks Kant…).
  6. REASON.  We’ve already touched on this briefly, but the reason for why one does science is for efficiency.  The reason for philosophy is a search and understanding for meaning.

A Quick Note on Transcendence and Immanence

by Max Andrews

The Enlightenment restricted knowledge to experience and the phenomenal. Post-Enlightenment thought sought to progress in knowledge while considering the advances the Enlightenment had made.  The Christian faith attempted to develop a new relationship between transcendence and immanence.  Transcendence has to do with God’s being self-sufficient and beyond or above the universe.  Immanence corresponds with God being present and active in creation, intimately involved in human history.  Newtonian physics did not permit God to be immanent in the universe.  This came into question was brought into light by the unmistakable success of science.[1]

Einstein’s GTR permitted the possibility that God interacts with the created order without interrupting the physical cause and effect system.[2]  The most important task for scientific theologians was how to avoid de facto deism—not merely by calling it unorthodox and expressing a dislike for the Newtonian theistic system, but by actually showing why it is an unnecessary conclusion drawn from science.  Christian theologians must be in the position to say what they mean by God’s activity in the world and how God’s activity can be consistent with the belief that God has created a finite order with a goodness and perfection of its own.[3]

Einstein’s Impact on the Epistemic Method

by Max Andrews

Lorenzo Valla (1406-1457) developed the interrogative (interrogatio) rather than the problematic (quaestio) form of inquiry.  Valla’s mode of inquiry was one in which questions yield results that are entirely new, giving rise to knowledge that cannot be derived by an inferential process from what was already known.  This method was similar to the works of Stoic lawyers and educators like Cicero and Quintilian; that is, questioning witnesses, investigating documents and states of affairs without any prior conception of what the truth might be.  Valla transitioned from not only using this method for historical knowledge but also applied it as “logic for scientific discovery.”[1]

Valla’s logic for scientific discovery was the art of finding out things rather than merely the art of drawing distinctions and connecting them together.  He called for an active inquiry (activa inquisitio).  John Calvin (1509-1564) applied this method to the interpretation of Scripture and thus became the father of modern biblical exegesis and interpretation.[2]  Francis Bacon (1561-1626) applied it to the interpretation of the books of nature, as well as to the books of God, and became the father of modern empirical science.[3]

This methodology created a split between subject and object, knowing and being, and gave rise to phenomenalism.  Newton claimed that he invented no hypotheses but deduced them from observations produced rationalistic positivism, which engulfed contemporary European science.  This split’s gulf was widened by David Hume’s (1711-1776) criticism of causality, depriving science of any valid foundation in necessary connections obtaining between actual events and of leaving it with nothing more reliable than habits of mind rooted in association.[4]  Hume weighed heavy in Immanuel Kant’s (1724-1804) philosophical development.  Given the Newtonian understanding of space and time, Kant transferred absolute space and time from the divine sensorium to the mind of man (the transfer of the inertial system), thus intellect does not draw its laws out of nature but imposes its laws upon nature.  According to Kant one cannot know the Ding an Sich (thing itself) by pure reason; one is therefore limited to the sensual and shaping mental categories of the mind.  That which comes through sensation the intuitions are shaped by the mind’s a priori categories.  It is in this sense that Kant played an essential part in the development of the idea that man is himself the creator of the scientific world.

Throughout Einstein’s work, the mechanistic universe proved unsatisfactory.  This was made evident after the discovery of the electromagnetic field and the failure of Newtonian physics to account for it in mechanistic concepts.  Then came the discovery of four-dimensional geometry and with it the realization that the geometrical structures of Newtonian physics could not be detached from changes in space and time with which field theory operated.  Einstein stepped back into stride with Newton and his cognitive instrument of free invention.  It was free in the sense that conclusions were not reached under logical control from fixed premises, and it was invented under the pressure of the nature of the universe upon the intuitive apprehension of it.  Einstein used Newton and Maxwell’s partial differential equations in field theory to develop a mode of rationality called mathematical invariance.  Mathematical invariance established a genuine ontology in which the subject grips with objective structures and intrinsic intelligibility of the universe.[5]

Einstein’s categories are not some form of Kantian a priori but conceptions that are freely invented and are to be judged by their usefulness, their ability to advance the intelligibility of the world, which is dependent of the observer.  As he sees it, the difference between his own thinking and Kant’s is on just this point:  Einstein understands the categories as free inventions rather than as unalterable (conditioned by the nature of the understanding).  Einstein asserts that the real in physics is to be taken as a type of program, to which one is not forced to cling a priori.[6]

Principles of method are closely related to empirical observations.  As Einstein put it, “the scientist has to worm these general principles out of nature by perceiving in comprehensive complexes of empirical facts certain general features which permit of precise formulation.”[7]  These principles, not “isolated general laws abstracted from experience” or “separate results from empirical research,” provide the basis of deductive reasoning.[8]

There is a long tradition within Christian theology of drawing on intellectual resources outside the Christian tradition as a means of developing a theological vision.  This approach is often referred to by the Latin phrase ancilla theologiae (a ‘handmaid of theology’).  The evolution of thought and method from Newton to Einstein vitalized scientific theology.  Scientific theology argues that the working methods and assumptions of the natural sciences represent the best—or the natural—dialogue partner for Christian theology.[9]

Here too logico-deductive argumentation from static concepts and mechanistic systems are rejected.  There is another reorientation of man’s knowledge leaving epistemic and cosmological dualism behind in operations that have to do with the unity of form and being.  Scientific theology is concerned with the discovery of appropriate modes of rationality or cognitive instruments with which to enter into the heart of religious experience, and therefore with the development of axiomatic concepts with which to allow interior principles to be disclosed, and in that light to understand the rational structure of the whole field of God’s interaction with man and the world.[10]

Scientific theology takes Einstein’s knowing and being and his understanding of reality as a whole and applies this method of theology in Christian theology.  If the world is indeed the creation of God, then there is an ontological ground for a theological engagement with the natural sciences.  It is not an arbitrary engagement, which regresses back to Newtonian engagement, but it is a natural dialogue, grounded in the fundamental belief that the God about whom Christian theology speaks is the same God who created the world that the natural sciences investigate.[11]
