A Fallacy of Cosmic Proportions – the Kalam Cosmological Argument

A further response to Gary Robertson’s Is naturalism more probable than supernaturalism? which was a rejoinder to Naturalism vs Supernaturalism – the False Dichotomy


Most contemporary philosophers regard the cosmological argument as unconvincing. Despite the best efforts of William Lane Craig, the famous argument never recovered from the assault it took at the hands of David Hume and Immanuel Kant. According to the Stanford Encyclopedia of Philosophy, even noted theologian, Alvin Plantinga concludes “that this piece of natural theology is ineffective”. Other philosophers similarly reject the argument: Michael Martin (1990: chap. 4), John Mackie (1982: chap. 5), Quentin Smith (Craig and Smith 1993), Bede Rundle (2004), Wes Morriston (2000, 2002, 2003, 2010), and Graham Oppy (2006: chap. 3).

To hang one’s metaphysical hat on the cosmological argument is to watch it sail away on the breeze.

William Lane Craig’s recent form of the Kalam Cosmological argument:

  1. Whatever begins to exist has a cause.
  2. The Universe began to exist.
  3. Therefore, the Universe had a cause.
William Lane Craig

Gary Robertson disagrees the KCA invokes the fallacy of composition by applying the same principle of causality which applies to the universe’s constituent parts, to the universe as a whole. Citing philosopher Edward Feser, who unconvincingly asserts that “it is hard to see how” things which are individually contingent are no less contingent when part of a group, the objection conveniently ignores what is so special about the mystery of existence.

The universe is not merely just an assortment of planets and stars. The riddle of existence, “Why is there something rather than nothing?”, would not be a riddle if it could be so simply answered, “it must have been caused!”. The riddle is founded upon Parmenides famous statement – “from nothing, nothing comes”. So, when musing about the answer to existence itself, the question becomes perspicuously different. We are now talking about the origin of existence itself, and why does it exist instead of nothing at all, and how and whether it arises from nothing.

Further, the powerful and interacting forces of nature, such as the pulling and repulsing of gravity, which determine the complex relations between physical things within the universe, tells us emphatically that reality is more than just a hamper full of stuff. The universe is not a glass menagerie, nor is it a bag of mixed lollies.

We could further speculate on the origin of the principle of causality. One assumes that the theist would say it was part of God’s creation. Viz. not an eternal principle. Thus, it’s circular and self-referential to invoke the causal principle to explain the existence of the universe of which it is a part.

And so, for the aforementioned reasons, it is indeed a fallacy of composition to assume that what is true of causality in the universe applies to the universe itself.

Gary Robertson disputes my objection to premise 1 of the KCA, that the universe had a beginning, by claiming the consensus of physicists and cosmologists agree the universe had a beginning. This may well be true, but I could more powerfully argue that a larger consensus of physicists and cosmologists reject a supernatural cause of the universe. As stated, a consensus of philosophers rejects the KCA! A consensus, being a survey of opinions, does not prove anything. Thus, the challenge to premise 1 remains.

Gary claims a brute fact, in the sense of an eternal force governing all of nature, can be ruled out, because it would have to exist before the Big Bang and be either timeless or self-caused. Thus, it would either transcend or sit outside of nature. But this objection only suggests such a force would sit outside of Gary’s rather narrow view of “nature” – which evidently constitutes the known universe from the time of the Big Bang.

Even on Gary’s definition this does not preclude a “supernatural” force. But if we did discover such a force, or identify it through evidence gathered in the material world, it’s only a matter of semantics as to whether we would name it as natural or supernatural. Thus, it’s a reification fallacy, given that human definitions have no bearing on what actually exists in the universe. Further, scientists consider the prospect of multiverses to be eminently possible, but none posits these as supernatural, as they would be under Gary’s definition.


Brute Facts and Necessary Beings

nexessary being

The denial of God as a brute fact highlights the special pleading required to insert God as a necessary cause. Gary Robertson cites Broussard (2016) who exempts God from being an unexplained brute fact, because his existence is explained by his essence. It seems childish and unnecessary to point out how circular this argument is – how can the essence of a hypothetical, unverified being ever be established – not to mention how it might be used in favour of any potential being, thing or force.

From the Stanford Encyclopedia of Philosophy entry on the Cosmological Argument:

“If theists are willing to accept the existence of God as the necessary being as a brute fact, why cannot nontheists accept the existence of the universe as a brute fact, as a necessary being? Bede Rundle, for example, argues that what has necessary existence is causally independent. Matter has necessary existence, for although it undergoes change as manifested in particular bits of matter, the given volume of matter found in the universe persists, and as persisting matter/energy does not have or need a cause. This accords with the Principle of Conservation of Mass-Energy, according to which matter and energy are never lost but rather transmute into each other. As indestructible, matter/energy is the necessary being. Consequently, although the material components of the universe are contingent vis-à-vis their form, they are necessary vis-à-vis their existence. On this reading, there is not one but there are many necessary beings, all internal to the universe. Their particular configurations are contingent, but since matter/energy is conserved it cannot be created or lost.”

The theist argues that the existence of the universe points to a necessary being – since all contingent things look to something else for their existence. Thus, the creator is a necessary being.

But the theist also maintains that the universe at some point did not exist, and in fact, was created from nothing by the necessary being. This indicates that the description of a creator as a necessary being is contingent on his own decision to create a universe, in such, that if the universe did not exist there could be no necessary being. Since the universe could have failed to exist by the theists own argument, then the concept of a necessary being becomes self-defeating.

hume's necessary being

Finally, even if we accepted the Cosmological argument, it still doesn’t get us to God. If we accepted the logic that everything has a cause, this does not demonstrate a cause which is “supernatural”, or some kind of deity.

The further arguments B and C presented to purportedly deduce the nature of a cause are silly arguments. For instance:

“B. It is logically impossible to provide a natural explanation for how nature came into existence as such an explanation must assume the existence of nature in its opening premises, thus committing the circular fallacy.”

No, it may mean that nature contains another element which is as yet unobserved. Or even an existing element of nature which has the, as yet unrecognised, property of seeding the universe. Further, a brute fact is a candidate because, by definition, it has no explanation.

The theist is all too keen to fill any uncertainty with supernatural explanations. As per my previous post, it will not be philosophers who solve the riddle of the universe’s origin. It will not happen by using logic. The secrets of nature have been gradually revealed using the scientific method. Cosmologists, astrophysicists and many other scientists continue to search the universe for answers. It is now time to dispense with the semantic trickery of the cosmological argument and indeed the other discredited logical arguments, and look to Hadron colliders, telescopes and space probes for the answer.

Naturalism remains undefeated: an answer to Plantinga’s Evolutionary Argument against Naturalism

Naturalism remains undefeated – a rejoinder to the Alvin Plantinga argument used in Post 3 that naturalism is self-defeating. Post 5.


lightning church

Popularizing the claim that naturalism and evolution are mutually self-defeating, Alvin Plantinga argues in the Evolutionary Argument Against Naturalism (1993), that, given unguided evolution, our beliefs have no intrinsic relation to the truth.

Drawing on previous arguments made by C.S. Lewis and Arthur Balfour, Plantinga claims that if humans are the product of undirected processes, then we cannot reasonably rely on what we perceive. In fact, it’s just “as likely …that we live in a sort of dream world as that we actually know something about ourselves and our world.”

Thus, if we cannot rely on our beliefs, then we cannot rely on our belief in naturalism and thus, naturalism is defeated.

Well, it would be very worrying if we couldn’t rely on any of our beliefs. But evidently, humans have good reason to rely on their cognition, and we do so in myriad situations daily.

We also have no reason to distrust the accepted science of evolution and the various mechanisms which operate within it; such as the mutation of genes, natural selection, and genetic drift.

Given there is no reason to discount both our cognitive capacities and the science of evolution, then the argument becomes problematic. Another way of expressing Plantinga’s argument is that we should distrust our knowledge of evolution based on our knowledge of evolution. Nonsense.

Second, even if we somehow accepted the unreliability of our beliefs, this would mean only that we could not rely on our belief in naturalism; not that naturalism is untrue. But, nor could we rely on our cognition that it is false. Therefore, if true, the unreliability-of-beliefs premise is either self-defeating for beliefs in naturalism and theism, or not self-defeating for both. Thus, it gets us precisely nowhere.

Third, the argument presumes that theism somehow provides humans with reliable cognition.

Plantinga explains,

“God has created us in his image, and an important part of our image bearing is our resembling him in being able to form true beliefs and achieve knowledge”.

But, inserting a supernatural element (God) as a fact, is a circular argument. Viz. if God exists, naturalism must be untrue, so there’s no use invoking God as evidence that naturalism is untrue. (Prove God exists first!).

Further, the Philosopher William Ramsay has observed how human faculties are, in fact, slightly unreliable – look at our impressive array of cognitive biases! Ramsay further posits that evolution and naturalism explain this better than theism. In fact, the well-established foibles in our thinking pose a considerable challenge to Plantinga’s suggestion that we are the perfect perceivers of truth one would expect as the product of an omnipotent Creator.

Plantinga’s argument trades upon the philosophical knowledge-problem: the difficulty in providing a neat solution to the foundation of knowledge: how do we know we can rely on our beliefs? But this philosophical problem is not specific to either evolution of naturalism: the challenge pertains to all of our beliefs.

In fact, our evolution by natural selection justifies a moderate level of trust in our cognitive faculties. The brain size of the various human species has increased from 400cc to 1350cc over several millions of years. In this time, archaic humans developed more sophisticated stone tools, harnessed fire, developed language, and began to use symbolic thought. Natural selection seems to have been effective in providing reproductive advantage by selecting for those traits. Claiming this is “accidental” misunderstands natural selection. Increases in brain size and thinking ability, are selection effects we could expect to correlate to accurate perceptions about reality. Indeed, it is hard to imagine how we could have survived as a species if our perceptions and beliefs have no relation to the real world.

Nevertheless, Plantinga draws strength from a quote of Darwin expressing worry about the veracity of evolved human thought.

“But then with me the horrid doubt always arises whether the convictions of man’s mind, which has been developed from the mind of the lower animals, are of any value or at all trustworthy. Would any one trust in the convictions of a monkey’s mind, if there are any convictions in such a mind?”

— Charles Darwin, to William Graham 3 July 1881

One can only wonder whether Darwin would have revised his doubts had he been able to witness the magnificent confirmation of his theory of natural selection via subsequent discoveries in the fossil record, and the field of genetics.

Natural selection has become the cornerstone of modern biology. There is no longer any doubt about the fact of our unguided evolution from prior species, and our connection to other forms of life.

Indeed, the yearning to understand our world has been a feature in the development of humans. When we observed natural events that we could not explain, we posited underlying causes. Recall, hunter gatherers performing rain dances, ancient tribes sacrificing animals and children. Up until the last 500 years, theology posited supernatural causes for most unexplained phenomena. In the 18th century hundreds of church bell ringers were electrocuted, as they tried to ward off the devils who cast lightning upon the earth.

To the current day, science and religion offer competing views of how to understand the world. Science uses the scientific method which relies on hypothesis, testing and prediction, and is always subject to revision. Theologians will always seek to explain mysteries by inserting supernatural elements such as ghosts and deities.

But science has uncovered other invisible, underlying causes of natural events. These include things like electromagnetism, gravity, and Heisenberg’s uncertainty principle. Needless to say, none of these could be arrived at through intuition alone. The gradual accumulation of scientific knowledge, where the work of one scientist enabled another, has helped humans to understand physical forces which are deeply counterintuitive; even, seemingly incomprehensible. Think of how light behaves as a wave and a particle at the same time; how particles can seemingly exist in multiple places at the same time; of how the universe is only 5% matter, the rest being made of dark matter and dark energy.

The invisible forces have been discovered and thus, we no longer need supernaturalism. We have no need to postulate other undefined and unverifiable forces. We certainly have no reason to entertain the idea that the discoveries of science are vulnerable to a superimposed truth-giving deity. Plantinga’s argument is but a rationalization allowing theists to question evolution and naturalism. But it relies on doubting accepted science, and inserting a supernatural element, and thus, is itself, self-defeating.
