The BlackSapientia Digest

Classical theism describes God as the uncaused, necessary being who has no beginning and no end, exists outside of time, and requires nothing else for His existence. This is the God of Aquinas, Augustine, Anselm, and the major Abrahamic traditions. But here's a strange thing: I never questioned that definition until one afternoon when I did something embarrassingly simple. I opened a dictionary. Not a theology textbook. Not a philosophy journal. A plain, everyday dictionary. And within thirty seconds, I realised that the God of classical theism cannot exist, not because of a complex logical paradox, but because of how the word "existence" actually works. However, let me show you what I found.

Frequently Asked Questions 

Isn't it a category mistake to apply a human dictionary definition to God? 

That's a fair objection, and classical theists like Thomas Aquinas would agree that we cannot apply words like "existence" to God in the same way we apply them to creatures. This is the doctrine of analogical predication. However, the problem remains: for an analogy to work, there must be some real similarity between the two uses. What similarity does "existence" have when applied to a finite, time-bound cat versus an infinite, timeless God? The cat began; God did not. The cat will end; God will not. The cat is contingent; God is necessary. They share no common feature of "existence." Without a shared anchor, the analogy collapses into equivocation, using the same word to mean completely different things. At that point, saying "God exists" tells you nothing more than "God flibbertigibbets." So either the word loses all informative content, or we admit that God does not "exist" in any normal sense, which means classical theism's central claim is either false or meaningless.

What about abstract objects like numbers or logical truths? They don't have a beginning or end, but we say they "exist" all the time.

This is a sharp counterexample, and philosophers debate it extensively. However, note two key differences. First, when mathematicians say "numbers exist," they usually mean they have abstract existence outside space and time, without causal powers, consciousness, or agency. The God of classical theism is supposed to be a concrete being who creates, acts, and responds. Concreteness and timelessness are a notoriously difficult combination (how does a timeless being act at a specific moment?). Second, many philosophers (nominalists) deny that abstract objects "exist" at all; they say numbers are useful fictions or linguistic conventions. But even among realists, they admit that "existence" for numbers is radically different from "existence" for dogs. The blog post's argument is directed at the concrete, personal, causal God of classical theism. If you want to say God exists like a number exists, as an abstract, non-causal, non-temporal entity, then you have abandoned the God who answers prayers, creates universes, and performs miracles. Most believers aren't willing to do that.

But the dictionary definition of "existence" doesn't explicitly say "requires a beginning and an end." Isn't the blog post reading that into the examples?

Good eye. No dictionary says "existence = having a beginning and an end" as a formal definition. The point is implicit in every single usage example. Try a test: find one dictionary example sentence where the subject of "existence" has no beginning and no end. You won't. Why? Because the English language does not need such a sentence, we never encounter beginning-less things. The concept of "existence" is inextricably tied to temporal boundedness in practice. That's not a logical flaw; it's a linguistic fact. The blog post is not claiming that the dictionary explicitly defines God out of existence. It is claimed that if you take the word as it is actually used, a beginning-less, endless being fits no known model of "existence." So you have two choices: either change the definition (special pleading) or admit that classical theism uses "exists" in a way disconnected from ordinary language, which makes the claim unfalsifiable and arguably meaningless. The 30-second test is a rhetorical device, not a formal logical proof, but it reveals a genuine problem that theologians have struggled with for centuries.

A Personal Discovery Narrative (The 30-Second Accident)

I was writing an Essay about whether unicorns "exist" in mythology versus reality. To be precise, I looked up "existence" on my phone. Merriam-Webster, first result:

1. Existence: The state of having actual being; continuance in being. That seemed fine. But then I scrolled to the usage examples. Every single one referred to things that began at some point and will end at some point: "the existence of dinosaurs," "the existence of poverty," "the existence of life on other planets." Nevertheless, not one example of something that never started and never stops.

I tried other dictionaries. Cambridge: "the fact of something or someone being real." Their examples: "Scientists are investigating the existence of a new species." A new species has a beginning. Oxford: "the state of living or having objective reality." Examples: "The organisation has been in existence for 15 years." Fifteen years implies a start date. That's when it hit me: We never use the word "existence" for anything that lacks a beginning and an end. Not once. Not in any ordinary sentence. If I said, "A number has existence but no beginning," you would correct me: numbers don't exist that way; they are abstract. However, if I said, "The universe exists without a beginning," a physicist would say, "Actually, the Big Bang suggests it began."

So I asked myself: if the God of classical theism has no beginning and no end, in what sense does this God "exist"? The dictionary doesn't have a separate definition for divine beings. The same word applies to rocks, rabbits, and galaxies. And every rock, rabbit, and galaxy began. That accidental lookup turned into an hour of reading. And by the end, I couldn't unsee it.

Word Origin: Where "Existence" Actually Comes From

To understand why the dictionary definition matters, let's look at the word's roots. "Existence" comes from the Latin existere (or exsistere), which breaks down into:

i. Ex: Meaning "out of" or "from"

ii. Sistere: Meaning "to stand, place, or cause to stand"

Literally, existere means "to stand forth, to emerge, to appear." In ancient Roman usage, something existed if it had stepped out of non-being into being. It had emerged from a prior state of not being there. The word inherently implies a transition, a starting point. You cannot "stand forth" if you have always been standing. You cannot "emerge" if you were never hidden.

Even the Greek equivalent, hypostasis (often translated as "existence" or "substance"), carries a sense of standing under or coming to be. The pre-Socratic philosophers contrasted genesis (coming into being) with phthora (passing away). Something that neither comes into being nor passes away was called aidion (eternal), but they specifically did not say it "exists" in the same way as perishable things. Plato called the Forms "eternal," but he struggled to say they "exist",  he used ontos on (truly being) to mark the difference. So the very history of the word "existence" ties it to temporal emergence. A beginning is baked into the etymology. You cannot strip that away without breaking the word.

Theological Implications: Why Classical Theism Can't Escape This

Now let's apply this to the God of classical theism. The standard divine attributes include:

1. Aseity: (self-existence, not caused by another)

2. Eternality: (no beginning, no end; often timelessness)

3. Necessity: (cannot exist)

At first glance, these seem majestic. But under the dictionary definition and etymology, they become contradictions. Why? Because "existence" is a temporal predicate. When we say something exists, we implicitly place it on a timeline with a start date (even if unknown) and an expected or potential end date. If you remove both, you are no longer talking about existence; you are talking about something else entirely. Call it "eternal subsistence," "necessary being," or "the ground of all reality." But do not call it existence, because that word belongs to the realm of beginnings and endings.

Classical theists often respond: "God exists in a different sense, analogically, not univocally." Thomas Aquinas said we predicate "existence" of God only by analogy. Fair enough. But here's the problem: analogy requires a shared anchor. When I say "John is healthy" (applies to a person) and "this food is healthy" (applies to food), the anchor is the same concept of health (promoting bodily well-being). What is the anchor for "existence" when applied to God versus a dog? A dog began; God did not. A dog will end; God will not. They share no common feature of existence. So the analogy collapses into equivocation, using the same word with no shared meaning.

Other theologians (Paul Tillich, John Macquarrie) admitted this and said God is "being-itself" rather than "a being who exists." That is intellectually honest. But that is not the God of classical theism, who is a personal agent who creates, responds to prayers, and interacts with history. A being-itself does not part the Red Sea. Thus, the dictionary definition doesn't just challenge a minor point of theology. It reveals that the God of classical theism cannot be said to "exist" in any recognisable sense. And if a being does not exist in the recognisable sense, then that being is not real or at least, the claim "God exists" is meaningless.

Shareable Takeaway: What You Can Say Next Time

So here's the one-paragraph summary you can share with a friend, post on social media, or keep in your back pocket:

1.  "I looked up 'existence' in a dictionary. Every definition and example assumed a beginning and an end. The word comes from Latin existere 'to stand forth, to emerge.' You can't emerge if you never began. The God of classical theism has no beginning and no end. Therefore, God cannot 'exist' in the actual meaning of the word. You can call God eternal, necessary, or the ground of being, but then stop saying 'God exists' as if that means the same thing as 'my cat exists.' Language matters. And by the rules of language, the classical theistic God fails the definition of existence."

2. Your 30-second challenge: Open any dictionary right now. Look up "existence." Read the examples. Ask yourself: Does any example describe something without a beginning and an end? If not, then ask: why would we make an exception for God? That exception isn't logic; it is special pleading.

Wind Up

Furthermore, this doesn't prove there is no divine reality. It proves that the word "existence" cannot hold the weight classical theism places on it. So the next time someone says "God exists," ask them: "In the dictionary sense of 'existence', the one that applies to trees and toasters or in a completely new, made-up sense?" Their answer will tell you everything. What do you think? Is this a semantic trick or a genuine philosophical problem?
