The God of Anselm is understood as "that than which nothing greater can be conceived." From this definition, God can be presumed to be omnipotent, omniscient, omnipresent, perfectly free, uncaused, eternal, morally perfect, etc. God is fashioned as an infinite being, i.e. one who's abilities have no non-logical limitations. This definition, however, leaves us in an awkward epistemological position, as it ostensibly renders all potential evidence for such a being inherently ambiguous.

To speak specifically, any miracle, feat, or theophany wrought by an infinite being could—in principle—have also been performed by a finite being. That is to say, there seems to be an ineradicable ambiguity in any manifestation of an infinite being's power, precisely for the reason that the very same action could have been performed by a being that was not infinite. How might we finite beings ever know, definitively, which being we are actually dealing with?

How could any being, even God, possibly demonstrate His omnipotence? Omniscience? Moral perfection? How could we ever tell the difference between God and a being that is merely “God-like”? It would appear that these infinite attributes are—by their very nature—incapable of actual demonstration, and are thus intrinsically unverifiable. I am at a loss to explain how apologists set out in earnest to adumbrate the case for an infinite God when unambiguous evidence for such a being appears to be in principle unattainable.

Consider an analogous situation: Imagine that you are sitting in a room with nothing in it apart from a chain which enters from one side of the room and exits through the other side. From your vantage point you cannot see the outside world, but you can see that the chain clearly does not begin or end within the confines of the room. We are then asked, “Is this chain infinite?” How can our answer be anything other than a guess? What evidence or argument could possibly be adduced that would settle the matter definitively? It would appear that we are in no position to know which type of object we're dealing with, and therefore cannot verify that the chain is in fact infinite, even if it actually is. This epistemic hurdle seems to parallel any and all attempts to marshal evidence for an infinite God based on human experience (no matter how ineffable). Even if we were to experience the unmistakable presence of a powerful, immaterial, and personal being, we seem nevertheless to be in no position to say whether or not this being is essentially infinite.

How can we have unambiguous evidence for an infinite being if we cannot even verify that the being is infinite? How do we know it's not all in our heads? Perhaps to professional philosophers this not as big a problem as it appears to a layman like myself, but every time I try to think of ways to empirically justify theism, I fail to progress beyond this notion that any evidence for an infinite being is simultaneously evidence for an finite being. Am I completely off-base here?

  • Did you clearly define "infinite being?" What makes you think you're not already one yourself? A million years from now the atoms in your body will be repurposed to some other use. You never die, you only become a different aspect of the universe. You are as infinite as the universe is. Since it's clear that you never die, but just become a different part of the universe, what makes you think you're not already an infinite being? Or a part of one?

    @user4894 For one example, I cannot change the past, ergo I am not an infinite being. There is no need to persist in a Wittgensteinian obsession with language. For our purposes infinite equals unbounded, limitless, or essentially perfect.

    If you refuse to define what you mean, your question is meaningless. Where did this "change the past" rule come from? What is limitless? You are just making up words and imagining they have meaning to others. That's why in philosophy it is essential to define your terms. Else we aren't talking about anything. Oooh X isn't infinite because X can't cheat at solitaire. That's the kind of nonsense you fall into when you refuse to make a definition of your terms. What is "essentially perfect?" Is there an inessentially perfect? You're just making up buzzwords without meaning.

    @user4894 Cards on the table, I completely agree with you that the concept of an unsurpassably great being is nonsense. My ontological objections to theism are diverse and numerous. However, I was willing to elide them on the basis that if I only knew logic better perhaps it would make sense to me. However, this abiding problem of what I will call "Divine Demonstration" has prevented me from accepting it. I agree that retro-causality may be a poor example as it is more contentious than instructive. But what about moral perfection? Could we tell the difference between a virtuous being and God?

    By "virtuous" I mean exemplifying moral virtues to an incredible degree. Can we tell the difference between being incredibly virtuous and infinitely virtuous? Based on my limited understanding, I don't think we can. I am therefore surprised that anyone defends the claim that an infinite being exists given that we would not know infinity if it were staring us in the face.

Taking this as the core question:

How can we have unambiguous evidence for an infinite being if we cannot even verify that the being is infinite?

The short answer is: We cannot.

Assuming that we humans have finite powers of perception, it is impossible to distinguish a being that exactly fills our perception window from one that extends beyond it.

For example:

  • Any being that knows everything that we are able to verify is indistinguishable from an omniscient being: Any claim made by such a powerful (but not omniscient) entity outside our power to verify said claim may or may not be truth - say, claims about the native inhabitants of the 2nd planet around alpha centauri.

  • Any being that that can seem to be anywhere we are able to look is indistinguishable from an omnipresent being: Any place we can't look may be a place the powerful (but not omnipresent) being also isn't able to go - say, inside the planet's core or out in the Oort cloud.

  • Any being that can appear to do anything you can ask of it is indistinguishable from an omnipotent being: An interesting case would be a being with absolute power only in the domain of mental manipulation, being able to convince you and any number of co-witnesses (by creating false memories, etc.) without actually doing anything.

For an analogy:

Imagine that your entire life is spent in a large box with a single window looking out. Outside this window, all you ever see is a uniform, but pleasant, shade of mauve. This uniform mauve seems to extend in all directions, at least as best as you can determine by moving about in your box and using any tools that you have to try and improve your view.

  • Is the mauve infinite in time? Was it there before you (or historical records of the thought-experiment-historians) existed, will it continue after you exist? Is it there only when you're looking?

  • Is the mauve infinite in space? Maybe you're inside a small mauve bubble, or maybe the mauve ends a short distance beyond what you're able to see?

  • Is the mauve infinite in its powers of 'mauve-ness', or does it differ from 'true mauve' by some imperceptible degree? Does it change colour over timescales that your eyes/brain cannot detect/comprehend?

That said, as a species we've developed a pretty big perception-window that an infinite-being candidate would have to fill!

(And if one day we do encounter a being indistinguishable from an actually-infinite one we'll probably have to say 'Close enough. Now what?')

  • It's this "close enough" move that I am objecting to. Arguably, we could have said close enough at any point in history and been dead wrong about what we were witnessing. An exceptionally skilled illusionist could get the nod by the standards adumbrated in your answer. That said, I like where you are taking the question.

  • @BrysonS. - Fair call on the final parenthetical. I was more focused on the 'Now what?' when I wrote it, since a sufficiently-powerful being along those lines would probably force a complete re-think of physics at the minimum.

A god demonstrating his omnipotence would mean to make something which makes us convinced of his omnipotence. The simplest way to do that would be to manipulate our mind in a way that we believe in his omnipotence. An omnipotent god can almost certainly do that.

The only way an omnipotent god might not be able to do so (noticed by virmaior in the comments) is if there was a logical inconsistency, that is, if creating such a believe would inevitably destroy the ability to believe it. However evidence shows that we are able to believe all sorts of things, even against all evidence, and thus one can conclude that obviously our mind is able to hold believes independent of evidence. Indeed, many people even alrady hold the believe that there exists an omnipotent being, so that believe is not impossible. It is very unlikely that all people's minds being in such a state would be logically impossible if some people's mind being in that state isn't. If it is not logically impossible, an omnipotent god of course can put our minds in such a state.

  • It actually depends on how omnipotence plays out with respect to laws of logic. It's possible that omnipotence has limits such as not being able to coerce belief without undermining the capacity to believe. Moreover, the implications that God can do so and God does do so are different such that the mere absence of doing so does not imply that God cannot do so nor that God does not exist.

  • "Moreover, the implications that God can do so and God does do so are different such that the mere absence of doing so does not imply that God cannot do so nor that God does not exist." — That was not the question. The question was if it is possible that an omnipotent god demonstrates his omnipotence, not if it is inevitable, or even just if it would be a wise move for an omnipotent god to do so. Your argument about logical possibility is sound, but I'd say evidence speaks against it: People manage to believe all sorts of nonsense even against evidence, so obviously there are states …

There are logical arguments for proving the infinity of God. What you quoted from Anselm is, however, not an argument. The link you referenced does summarize his argument, but the validity and the actual implications of the argument are debatable.

Firstly Anselm’s argument is an indirect argument proven through reductio ad absurdum. Such arguments often don’t illuminate the essence of the subject under examination beyond the presumed definition. As in this case the argument doesn’t directly prove and elucidate the infinity of God, it only disproves his finiteness by arguing that finiteness indicates defect which contradicts the presumed definition, and as such God’s infinity follows. However the actual meaning and implications of infinity itself remains to be elucidated.

Also, Anselm’s argument suffers from a serious fundamental flaw. The problem is where Anselm confuses the concept of an infinite being with its actual external referent! Conceiving that which nothing greater than can be conceived, doesn’t imply the necessity of an actual infinite being in the outside world, because ‘infinite being’ when conceived in the mind (contrary to the external world) is just a concept and therefore limited and finite, whereas it is in reality that an infinite being is really infinite! This subtle and mind-boggling flaw was first pointed out by muslim philosophers.

Therefore Anselm’s argument fails to prove both existence and infinity of God. There are however valid arguments for both premises proposed by muslim philosophers following the Mulla Sadra’s school of Transcendent Philosophy which I refuse to explain here as they go off topic.

But assuming that an infinite God is indeed proven to exist we can deal with the rest of your question.

To speak specifically, any miracle, feat, or theophany wrought by an infinite being could—in principle—have also been performed by a finite being. That is to say, there seems to be an ineradicable ambiguity in any manifestation of an infinite being's power, precisely for the reason that the very same action could have been performed by a being that was not infinite. How might we finite humans ever know, definitively, which being we are actually dealing with?

The validity of the above statement (i.e. any manifestation of an infinite being can also belong to a finite being) can be questioned depending on one’s theory of God and His relationship to the creation. For example, if we take the theory of Unity of Existence (as advocated by Mulla Sadra), there’s in essence nothing in existence except God. That is, all that there is, all that is done trace back to the infinite God. God is the only actual actor and agent in existence. Creations are only His “beams and shades” who have no independent, separate existence of their own. So no act or perfection can be essentially attributed to the creation (i.e. finite beings).

But as for observable evidences of his infinity, one can just look at the infinite and endless expressions of life on Earth; the endless unique identities of individual instances of creation. The natural universe is considered by many metaphysicians to be infinite in size. That if proven could count as evidence of God’s infinity; in their own right, the endless number of stars and galaxies in the cosmos. Also consider the endless emergence of phenomena around you. The world is in constant motion and development and at each instant unique realities come into existence, endless settings, relations and combinations of things.

In the above statements, it is presumed that all supreme attributes of God find expression even in the most trivial of phenomena. An ant is as just inclusive of God's attributes as is Archangel Gabriel, however, an angel enjoys an extremely higher more intense degree of the Divine qualities.

    Two beings stand before you: one is infinite, one is not. How do you tell which is which? If you cannot, how do you even know that an infinite being exists without assuming it a priori? I am asking about evidence, not subjective impressions of the grandeur of the universe (which can be just as readily expressed in non-theistic terms).

    "one can just look at the infinite and endless expressions of life on Earth ..." -- But you are confusing "infinite" with "really really big." There are only finitely many atoms on earth and only finitely many possible combinations of atoms. There is in fact a finite amount of biological variation on earth. If you look at a large finite number and call it infinite, you will be led to faulty conclusions.

    @infatuated Can you quote any scientific evidence that the world is infinite? "All individual forms of being (animate or inanimate, living or lifeless) are completely unique and identical." -- Only finitely many people have ever lived and will ever live on earth. Finitely many. I can only repeat myself to point out that a large finite number is not infinite. Of course in a lyrical sense we all have "infinite potential," but that's not a statement about anything that exists in the actual universe. It's imperative to make this distinction.

    @infatuated: But if the universe is finite in time the number of states the universe will experience will again be mind-blowingly, computer-breakingly huge... but still, strictly speaking, a finite number.

Why or how the Infinite became the finite is an impossible question as it is self-contradictory. We can see this from another side when we seek to know how the Absolute has become the relative. Supposing we knew the answer, would the Absolute remain the Absolute? It would have become relative. What is meant by knowledge in our common sense idea? It is only something that has become limited by our mind, that we know, and when it is beyond our mind, it is not knowledge. Now if the Absolute becomes limited by the mind, It is no more Absolute; It has become finite. Everything limited by the mind becomes finite. Therefore, to know the Absolute is again a contradiction in terms. That is why the question has never been answered, because if it were answered, there would no more be an Absolute. A God known is no more God; He has become finite like one of us. He cannot be known. He is always the Unknowable One.

  • If there is a God, He is in our own hearts. Have you ever seen Him? It is an actual perception. Only the man who has actually perceived God has religion. Those who have perceived Him have perceived Him in a more intense sense then you see this external world. You will know the Truth because you have become the Truth. But it is done with great difficulty. Saints of different religions have realized Him through the power of introspection, he who has seen Him has seen the Reality, beyond being and non-being. He cannot be 'known' but He can be perceived. Jul 26, 2014 at 14:35

  • There is no proof or evidence in the sensual world. All proofs given in the sensual world are limited by time, space and causation and are therefore limited... All proofs in the sensual world are limited by the limits of language. Everything in the sensual world is limited. To those who have perceived the Reality, it is self-evident; no proof is required. Jul 27, 2014 at 2:35

There are two possible answers to the main question:

1) No, there can't ever be evidence for an infinite being,

2) There is evidence, but since human beings are incapable of "perceiving" it, it is the same as if there is no evidence.

In regards to the question, would we be capable of distinguishing between something performed by an infinite being or a "not so infinite" being? The answer would also be no, as long as the "not so infinite" being performance is also beyond our perception. If both performances are beyond our perception, we would not be able to tell which being did what?


Don't you see that what you described in your naive and fascinated way is already answer to your question? Your mental search and failure to find Is already a manifestation of something bigger than you.

That fascinating and magnificent thing/things going ON in your head while you write to us, do you see them as infinite and powerful manifestations of Gods?

Your imagination. You will not call it infinite?

Don't you see that finite is just another side of infinite? (think continuity)

Yes, pending a slight change to the question. (see A → B, below)

I suggest we utilize Solomonoff induction (LW's narrative intro for those who don't know some basic theory of computation) in order to examine the issue. I will need one other tool: the concept of a non-recursively enumerable set of axioms. I claim that there are two kinds of infinite being:

  1. infinite in number
  2. infinite in description

Many people seem to think in terms of #1, but I want to argue that this is not a helpful way to think. Instead, I say we should think of an infinite being as not being describable by a [finite] computer program. That is, no longer how many lines of code you right in your simulator of the infinite being, you'll always be in error. You could get closer and closer to describing that infinite being, but you'd never 'finish', except as t → ∞ (which may be what John 17:3 claims).

Solomonoff induction plays on the idea of simplicity, which is notoriously hard to define. We may, however, be able to use Kolmogorov complexity, as argued in The Computational Theory of the Laws of Nature (I suggest reading the section "God's Problem" and "God's language"). When we want to explain a sequence of observations, per Ockham's razor, we want to pick the simplest explanation. That would be the algorithm with lowest Kolmogorov complexity. So, I can rephrase the question:

Could a sequence of observations ever be best-explainable via a type-2 infinite being, where "best-explainable" means having lower Kolmogorov complexity than any description?

I claim that this, however, is not quite the right question. It asks us to explain what already is. What if we wish, instead, to predict the next observation? This is a subtle shift, from:

     A. What best explains a given sequence of observations?
     B. Where does a given sequence of observations most likely point?

If I am allowed to tweak your question from A → B, then we can talk about two different options for B:

     I. The next observation will be like previous, and require no increase in Kolmogorov complexity.
    II. The next observation will be different, and require an increase in Kolmogorov complexity.

If we run into enough II-type observations, I claim we are justified in inferring that our universe is infinite in description, via induction, despite the problem of induction. Furthermore, via Fitch's Paradox, the potential for infinite knowledge requires an extant omniscient being. So either everything that is knowable is already known, which would lock us into an epistemically finite universe, or there is an extant omniscient being, which means that being is infinite.

  • Would such an omniscient being "know" how to create new information? If so then it would create something previously unknown to it (which should be impossible), If not then there is something is presently does not know, namely how to create new information. Is the concept not self-contradictory?
    – Bryson S.
    Jul 19, 2014 at 3:07
  • @BrysonS., What requires an omniscient being to create new information? I'm a bit worried that this is going to rabbit-trail down a discussion of how divine attributes can intermingle, which seems like it is too far afield. That really ought to get its own question, linked from here, don't you think?
