Can materialism be true at all?

Materialism is the belief that matter is the ultimate reality, that is to say that everything is material so that there are no such things as souls or numbers.


In a previous post, I argued that materialism seems to be self-contradictory because the concept of “everything” appears to be irreducible to anything more fundamental.

In the following blog post, I want to reformulate my argument in a way that makes it easier to be analysed and criticised.

It basically goes like this:

1) According to materialism, every truth corresponds to a material state of affairs independent of human language, i.e. a combination of interacting particles located in space and time.

2) But the truth of materialism itself cannot correspond to any such combination of spatially and temporally located interacting particles.

3) Hence materialism cannot be true.

3) is entailed by 1) and 2).

Consequently, you have to reject at least one of these to avoid the conclusion.

Can the truth of materialism correspond to a material state of affairs?

First of all, readers might be astounded by my assertion in 2). I shall try to lay out here what I mean by it.

The truth of materialism means that ALL things are material. This in itself consists of two conditions.

A) Entity 1, entity 2…entity n (whereby n can be infinite) are material, that is to say combinations of interacting particles located in time and space.

B) Entity 1, entity 2…entity n (whereby n can be infinite) are everything that exists.

This is illustrated in the following figure.


Materialism cannot just depend on condition A). For it not only entails that the entities in the circle are material but also that they are ALL THERE IS, so that there is NOTHING outside the circle.

And that very property can neither be located in space nor in time. Nor can it consist of 100,00; 10E+34 or any other number of particles.

What are truths under materialism?

This naturally leads us to examine claim 1).

All materialists are nominalists which means that they reject the existence of abstract objects (such as numbers) that they view as useful human conventions aiming at describing the natural world.

They also believe that truths such as “It is dangerous to drive after having drunk a bottle of Vodka in five minutes” are ultimately nothing more than the product of human language describing material states of affairs, i.e. a representation in our brains of facts of the external world.


In that particular case, there is nothing over and above the fact that almost every actual human being having ever been in that state is totally incapable of coordinating a complex activity such as steering a car.

Now, what would it mean to reject claim 1)?

A first option would be to reject my assertion that a material state of affairs has to be a combination of particles located in time and space. It is certainly true that materialism itself isn’t well defined. But all materialists I know believe there are no objects outside of time and space and I think that any view denying this would deserve another name altogether.

Finally, you can reject my claim that materialism implies that every truth corresponds to a material state of affairs. That might perhaps be the best way to defeat my argument.
But at the moment, I fail to see how this could make any sense. Basically, this would amount to saying: “Everything is material but certain truths go beyond the material world” which sounds self-contradictory to me.

So I am under the impression that materialism cannot possibly be true.

I’d certainly be glad to learn where you think my reasoning is mistaken.


Could material facts account for the non-existence of any immaterial realms?

Someone objected that I haven’t proven that “there exists no immaterial realms” cannot correspond to a complex set of material states of affairs.

For materialism to be true, there must not be any immaterial parallel realm which has never been and will never be connected with our universe and has no common origin with it.

Could the particles in our universe along with their physical properties render the existence of such a realm impossible ?

Now, the state of the elementary particles making up our universe can have no logical consequence on a realm of existence that has never interacted and will never interact with them and that does not share any common origin with them.

This just isn’t possible unless the particles have some metaphysical power and would, thus, cease to be physical particles.

So I think that premise 2) is the safest part of my reasoning. Regardless of their spatial distribution and energy levels, the elementary particles our universe (or multiverse) is composed of cannot account for the fact of there not being anything else.


Why can’t “everything is material” just be such a material fact?

Someone said that my argument is fundamentally flawed because “everything is material” is a perfectly fine material fact.

At this point, it is important to reflect on the role of language and truth. For a materialist, concepts such as numbers, triangles, everything or nothing are only useful human conventions aiming at describing the empirical world. According to materialism, every truth corresponds to a material state of affairs independent on human language such as the temperature distribution on the surface of the sun.

So the sentences “there are no immaterial realms“, “The material multiverse is all there is” etc. aren’t physical facts as explained in premise 2).

Instead, if they were true they would be metaphysical facts as they would go beyond the physical world.

Whenever we imagine that the universe (or multiverse) is all that there is, we consider “everything” and “nothing” to be real features of the external reality rather than mere human conventions.

Can we define the truth of materialism?

In a previous post, I explained why I believe that materialism (the belief that matter is the only reality) cannot make sense of the truth of materialism.

The Red Spider Nebula: Surfing in Sagittarius - not for the faint-hearted!

My reasoning was hard to follow and this prompted me to try to reformulate my argument.

Platonism and Nominalism

According to Platonism, abstract objects not existing in space and time (such as numbers, mathematical operations, concepts such as “everything“, “nothing” etc.) are real and  necessary to talk about the world.

For instance, while considering the sentence

All roses in my garden are red


a Platonist will consider the words “all” and “red” as examples of abstract objects (or universals) which determine its truth or falsehood.

A Nominalist rejects the existence of abstract objects which are considered to be useful human conventions.

According to them, the above sentence can be rephrased as

“Rose number 1, 2, 3…. and N have roughly the same colour as tomatoes”

thereby seemingly doing away with the indispensability of abstract concepts.

It is important to realise that the plausibility of Nominalism stands and falls with its ability to reformulate such statements without the use of any abstract objects.

If abstract objects can be shown to be indispensable to give a meaning to a true sentence describing the real world, Nominalism is false.

What is the truth of materialism?

Materialists MUST be Nominalists as they reject the existence of anything not located in space and time.

At face value, the truth of materialism can be expressed in different equivalent ways:
Everything is material
There is nothing immaterial
If (any object)* A exists, A is material

If (any object)* A is real, A is material“.
But is there a way to formulate this proposition without (explicitly and implicitly) appealing to any abstract entities?

It seems to me that in that specific context, all words I have underlined are abstract entities or require the meaning of abstract entities such as existence.

The sentences “there exists no such thing as the concept of existence” or “the concept of reality is not real” appear self-contradictory to me.

Note that I am not saying that the underlined words cannot be interpreted nominallistically in other situations.

But here it seems impossible to me to express the truth of materialism while only appealing to material entities.

If I’m right about that, whenever we assert the truth of materialism, we must resort to non-material concepts. In other words, if the truth of materialism is meaningful, non-material concepts must be meaningful as well.

Conversely, if non-material concepts are meaningless, so is the truth of materialism.

Another way of looking at this is to consider the  truth-value of  materialism, that is to say the state of affairs of the world that would make it true.

Suppose that 2 billions years later, our highly advanced descendants feel confident that they know everything that exists.

Would the state of affairs corresponding to materialism simply be: “Object 1 is material, object 2 is material…object N is material“?

No, for it must also include “And objects 1 to N are everything that exists” or ‘”there is nothing else than objects 1 to N”.

It thus appears that as an ensemble, objects 1 to N must have a non-material property (namely that of exhaustiveness) that is not localised in time and space and cannot be identified with any set of interacting primary particles.

Therefore, the impossibility of defining materialism without relying on immaterial concepts goes hand in hand with the impossibility of it being true.

The Cosmos of materialists
The cosmos in a nutshell. Materialism implies BOTH that the entities in the oval are material and that the oval is all there is. This property of the oval is non-physical in that it cannot be localised in time and space.

I’d be interested to learn if you think I’m wrong and that you know such formulations which do not merely shift the problem. Of course, one solution of the issue might be to use more modest definitions of materialism that do not try to convey the idea of “nothing else”.


*Some might object that the sentence

If (any object) A is real, A is material

can simply be formulated as

If A is real, A is material.

This clearly raises questions about the implicit meaning of A.

The sentences

If love exists, love is material

If telepathy exists, telepathy is material

can obviously  not serve as the definition of materialism, although they naturally follow from its truth.

Nor can this role be played by the sentence

If Lyurmur exists, it is material

which concerns a specific entity called “Lyurmur“.

It is because of mathematical conventions and our use to them that we automatically assume that “A” in the original sentence means “any object having that property“.

It thus follows that we cannot do away with that concept in such a manner.


A creation of human brains

Someone answered that this isn’t a problem as “everything” can be viewed as an abstraction created by human brains.

If that is the case, without conscious lives in the cosmos, materialism couldn’t be true! Materialism would be a fact of the external world that would not be true if there were no consciousness. That’s certainly a very odd position to hold. Many would say it is plainly absurd as one of the main claims of materialism is the denial that consciousness is anything fundamental.
Moreover, if the concept of “everything” is only a useful convention to simplify our daily talks and theory building, then what does it mean in such a situation where it cannot be reduced to anything else?
I think that the following argument can be developed:
1) If the sentence M “everything is material” is true, then the concept of “everything” must exist either as such or as something reducible to other concepts or objects and not *merely* as a creation of the brain.
2) In that specific context, “everything” cannot be reduced to more fundamental objects.
3) Hence, if M (materialism) is true, “everything” exists as a fundamental object.
I have argued for 2) above and believe it is very implausible that anyone could reduce “everything” to something more fundamental and do away with abstract objects.
I shall thus take it for granted.
Denying 1) would mean that “A is…” can be true even though A does not carry any external meaning and is only correlated to a bunch of neurons. That too seems very implausible as the proposition “The fountain of youth is material” and “The fountain of youth is immaterial” are both false if the fountain of youth does not refer to a putative object.
Consequently, it is very hard to see how a materialist can consider that “everything” is nothing more than neural currents without meaning while believing that the sentence “everything is material” is true.
Not a noun?
Another person asserted that “everything is material” is perfectly fine for a materialist as “everything” is a pronoun and not a noun. I don’t think this is the case.

For an abstract object not existing in time and space does not have to be a noun in a specific language.
Consider for example the sentences:
0 roses are red
3 roses are red
7 roses are red
9 roses are red
NO rose is red.
ALL roses are red
EVERY roses are red.

“No”,”All” and “every” are as much abstract objects as “3”, “7” and “9” are.
If “0”, “3”, “7”, “9” have no meaning, neither do the four first sentences.
If “no”, “all” and “every” have no meaning, neither do the three last sentences.

“all” and “every” depend on the concepts of everything in the same way as “something” depends on the concept of something.

The sentence “Fijhfhdfgx is blue” is meaningless without a concept of “Fijhfhdfgx“.

What is more, everything in that context can only mean “every OBJECT” as opposed to “every pineapple or “every wild bears”.

So, I still don’t see how “everything” (every thing) can have a meaning here without the concept of everything and the concept of object.

Replacing “every” by an enumeration
Someone suggested I could just replace “every” by an enumeration of all elements making up reality.

I also first thought of “everything” as a summation (U).
If all the materialist was claiming were that the objects KNOWN TO US are material, an enumeration such as
– This laptop is material
– This rose is material
– Donald Trump’s brain is material
would indeed be perfectly correct.
The problem is that most materialists also include all potentially unknown object.And as such, the summation (U) will also have to explicitly mention
and all potential objects we know nothing about are material

so that the problem does remain the same.

This seems to be inevitable. Our descendants in 200 000 000 million years would also face the same problem as they too could not rule out the existence of unknown objects in, say, parallel universes.

So I remain convinced that phrases such as “and nothing else exists” cannot be replaced by any combinations of concrete objects.

 Actually, in order to avoid a tautology (such as ‘all material things are material’), it appears to me that you must allow for the possibility that the object A could be non-material. And as such, A cannot be considered a physical thing of our universe from the outset without begging the question.

On God’s hiddenness and the nature of faith

I was recently involved in an interesting debate about the nature of faith in God and the alleged moral guilt of disbelievers.

It revolved around the problem of divine hiddenness: if God really exists and is interested in people believing in Him, then why does He not unambiguously prove His existence?

God's hiddeness
God’s hiddenness: despite all the wonders delighting our eyes and filling our soul with awe, nature remains very ambiguous and conceals its ultimate reality.

The discussion took place in the comment section of a blog post written by progressive Evangelical theologian Randal Rauser entitled “Is the Atheist my Neighbour?


When I wrote Is the Atheist My Neighbor? I had a very short endorser wish-list. That list consisted of folks who were leaders in their professions and exemplars of the kind of irenic dialogue between atheist and Christian that was the book’s reason for being.

Neither Richard Dawkins nor Ray Comfort made the list.

One of the people who did make that list was J.L. Schellenberg, Professor of Philosophy at Mount Saint Vincent University. Schellenberg is an atheist and one of the leading philosophers of religion in the world today. His most important work in philosophy of religion is a powerful argument for atheism from divine hiddenness, an argument that he has honed over more than twenty years. Professor Schellenberg has pushed the dialogue and debate forward with a thoughtful and powerful argument, and all without animus or rancor. Indeed, while I have never met him, I know several Christian philosophers who count him not only an esteemed and worthy opponent, but a personal friend as well. You can visit Professor Schellenberg online at his website here.

All this is to say that I was delighted to receive the following endorsement from Professor Schellenberg for Is the Atheist My Neighbor? Given my goals in writing this book, an endorsement like this is worth its weight in gold, and that would hold even if the endorsement were etched in granite. The first sentence alone provides one of the best introductions to a book endorsement that I’ve ever read:

“There are some whose way of following the first of the great commandments has, in the matter of nonbelief, meant violating the second. In this brief and lively but remarkably full and acute discussion, Rauser shows the way out of this problem. Impressively fair, and writing not perfunctorily but with feeling, he has found a way to express genuine neighborliness both to atheists like me and to Christians who struggle to reconcile love and loyalty.”



Andy Schüler, a German Atheist reacted to another commentator arguing that rejecting God’s existence is never an innocent action.

Among many other things, he wrote:


Schellenberg´s argument requires that at least some people who are open to the possibility of God’s existence and do not resist this truth still live and die as unbelievers. If you interpret the Bible in such a way that the existence of such people is impossible – then your interpretation makes the Bible evidently wrong about this matter (in a way that makes any further discussions impossible, because it forces you to accuse people who claim that they indeed are sincerely open to the possibility of God’s existence, yet also sincerely do not believe that there is a God, of simply lying about this). 


You don´t teach your kid that he or she shouldn’t touch a hot stove by letting him touch it. Or rather – you would be a terrible parent if you did it). And the scripture you refer to depicts God in an even worse light, God is like a parent that is an extremely skilled mentalist and not only does nothing to stop his little kid from touching the hot stove, but rather uses his skills to convince him that he  should touch it!


My response follows. Please forgive me for the small pieces of German dialect scattered here and there 🙂

Hi Andy! 🙂
Long time, no see!
(Sit longi Zit hon ich nix meh von dir gehert!).

“Innocence or lack thereof has nothing to do with anything here. Schellenberg´s argument requires that at least some people are open to the possibility of God existing / not resisting the truth of this, yet still live and die as unbelievers.”

My own view is that people “dying as unbelievers” (or atheists for that matter) but sincerely and humbly striving for justice and love will inherit eternal life whereas people dying as egoistical self-righteous bigots will irremediably lose their existence and be no more.

In all his parables, Jesus never threatened anyone with hellfire for not believing in Him or engaging in sexual immorality but for
1) failing to feed the poor, weak, hungry or neglected
2) not repenting from one’s own unjust pride.

Even Paul himself didn’t embrace the whole view often attributed to him in that he wrote

“God “will repay each person according to what they have done.”[a] 7 To those who by persistence in doing good seek glory, honour and immortality, he will give eternal life. 8 But for those who are self-seeking and who reject the truth and follow evil, there will be wrath and anger. 9 There will be trouble and distress for every human being who does evil: first for the Jew, then for the Gentile; 10 but glory, honour and peace for everyone who does good: first for the Jew, then for the Gentile. 11”

If you read Roman 2, it seems quite clear to me that Paul believed in the salvation of righteous heathens dying as such, his other ideas notwithstanding.

It is ironic that those arrogant and unloving fundamentalists who keep preaching about “salvation by faith” and eternal torment are those who are the most likely to miss everlasting life, according to Jesus.

Given that, I find that Schellenberg´s challenges are far less impressive (albeit not entirely unproblematic, of course).

God is under no moral obligation to give clear evidence of His existence to atheists if their unbelief while dying isn’t going to damn them.

You’re quite right that we cannot make a choice about what we deem to be reasonable
(obwohl die Engländer das Wort “decide” sowohl als “entscheiden” als auch als “bestimmen”, “herausfinden” verwenden 🙂 )

Yet, the same thing cannot necessarily be said about our hopes .

Obviously, someone convinced that theism is extremely implausible cannot entertain any hope in that direction.

But what if you’re completely ignorant about whether theism or atheism is true?

Or what if you (as I do) believe there are intriguing pieces of evidence for the existence of a non-material world which aren’t, however, compelling?

It appears quite reasonable to think one can, in that case, consciously choose to entertain and cultivate hope in either direction.

One example might make that concept a bit more palatable.

Consider the proposition: “Our world is actually some kind of simulation run by beings we know nothing about . It all started five minutes ago with the appearance of age.”

Brain in the vat:
Brain in a vat. My thought experiment here is far broader than that and include the possibility of being part of a simulation of beings radically different from everything we can conceive of. Or being fooled by a deceitful demon about whose abilities and psychology we know nothing.

I’ve no doubt that most of us find that pretty absurd on an emotional level .
Yet, I do not think that anyone can show this to be widely implausible without begging the question and smuggling in assumptions about reality. And I spent quite a few hours exploring propositions aiming at rationally dismissing that possibility.
(You can try to prove me wrong if you so wish 🙂 ).

Therefore, I think that in order to ground our entire knowledge and existence, one has to take a leap of faith and make a pragmatic decision (Entscheidung) not based on whatever reasons.

On the Self Consistency of Reductive Materialism


Reductive Materialism (RM) is the belief that everything which is real is identical to interacting particles.


It is most likely the most popular form of atheism among Western elites.

The existence of truth has always been a problem for Reductive Materialism (RM), but I think a specific, obvious example suffices to show its self-defeating character.

My argument is described below.

1| everything which is real is identical to interacting articles(premise for the reduction)

2| the fact of RM is real

3| therefore the fact of RM is IDENTICAL to a specific set of particles in energy fields

4| not only can we not conceive of this, but the very idea of seeking for such a bunch of particles in the universe sounds utterly absurd

5| therefore RM is an utterly absurd worldview

Now I’m trying to consider all possible objections.

A proponent of RM might reject 2) but then her own worldview would become meaningless.

My guess is that all attacks will be concentrated on step 4|, she will tell me that there does exist a set of elementary particles identical to the truth of RM.

The best answer I could think of would be that the fact of RM is identical with all the matter in the entire universe. But there is a huge problem here: all the particles of the universe (or of the multiverse for that matter) do not contain in themselves the information they are alone and lonesome.


For the existence of all this particles forbids us by no means to think there are transcendent universes with transcendent laws of nature.

Therefore the (alleged) fact everything which is real is identical interacting particles cannot be identical to all existing material things because this don’t make the existence of other realms unlikely.

Now materialists might respond that the fact of reductive materialism is real and can be identified with a bunch of processes going on within human brains.

I would gladly accept the fact that the truth of materialism only exists within the brains of materialists.

Über die Selbstkonsistenz des reduktiven Materialismus


Der reduktive Materialismus (RM) ist der Glaube, dass alles, was real ist, mit wechselwirkenden Teilchen identisch ist.

Das ist höchstwahrscheinlich die beliebteste Form des Atheismus unter der westlichen Elite.


Die Existenz der Wahrheit ist immer ein Problem für den Reduktiven Materialismus (RM) gewesen, aber ich denke, dass ein besonderes, offensichtliches Beispiel seinen selbstzerstörenden Charakter offenlegt.

Mein Argument beschreibe ich in den folgenden Zeilen.

1| alles, was real ist, ist mit wechselwirkenden Teilchen identisch (Annahme für die Reductio Ad Absurdum)

2| die Wahrheit des RM ist real

3|deswegen ist die Wahrheit des RM mit einem spezifischen Satz von Partikeln in Energiefeldern identisch

4|wir können das gar nicht auffassen und die Idee selbst, nach einem solchen Haufen von Partikeln im Universum zu suchen, scheint völlig absurd zu sein

5| deshalb ist der RM eine völlig absurde Weltanschauung.

Nun versuche ich, all die möglichen Einwände zu berücksichtigen.

Eine Anhängering vom RM könnte 2| ablehnen, aber dann würde ihre eigene Weltanschauung sinnlos werden.

Ich errate, dass alle Einwände sich auf den vierten Schritt 4| konzentrieren werden, sie wird mir sagen, dass es wirklich einen solchen Satz von Partikeln gibt, der mit der Wahrheit des RM identisch ist.

Die beste Antwort, die mir eingefallen ist, wäre, dass die Wahrheit von RM mit der ganzen Materie des gesamten Universums identisch ist.
Aber es gibt ein riesiges Problem hier: all die Teilchen des Universums (oder des Multiversums, wenn man so will) enthalten nicht in ihnen die Information, dass sie allein und einsam sind.

Denn die Existenz all dieser Partikel verbietet uns keineswegs, zu denken, dass es transzendente Universen mit transzendenten Naturgesetzen gibt.


Deswegen kann die vermeintliche Wahrheit „Alles, was real ist, ist mit wechselwirkenden Teilchen identisch“ nicht mit allen existierenden materiellen Dingen identisch sein, weil  sie uns keinesfalls zeigen, dass die Existenz von anderen, transzendenten Welten unwahrscheinlich wäre.

Nun könnten Materialisten darauf antworten, dass die Wahrheit des reduktiven Materialismus real ist und mit einer gewissen Anzahl von Hirnprozessen identifiziert werden kann.

Ganz froh akzeptiere ich die Tatsache, dass die Wahrheit des Materialismus nur in den Gehirnen von Materialisten existiert.
