Are Moral Facts Real?

Beyond Good and Evil: The Cheat Sheet to Metaethics

 

Introduction

Most ethical debates center on applied questions: Is lying ever justified? Is taxation fair? But beneath these everyday arguments lies a deeper, more fundamental branch of philosophy: Metaethics. Rather than asking which actions are right or wrong, metaethics asks what goodness and wrongness actually are. Are moral claims objective facts built into the fabric of the universe like the laws of physics, cultural conventions agreed upon for convenience, or mere emotional outbursts disguised as truth? Understanding metaethics means investigating the very foundation of how we judge reality.

Metaethics—the study of what morality actually is (rather than just which actions are right or wrong).

Here is a breakdown of the common views, organized by how they answer the question: "Are moral facts real?"

Moral Realism (The "Objective" View)

This view holds that moral facts exist independently of our opinions, much like scientific facts (e.g., gravity or the shape of the earth).

• The Core Belief: "Killing is wrong" is a fact that is true regardless of what anyone thinks or feels about it. If the whole world voted that killing was okay, the Moral Realist would say the whole world is simply mistaken.

• Analogy: Math. $2+2=4$ is true whether you like it or not.

Moral Anti-Realism (The "Subjective" Views)

This is the broad category for views that deny that objective moral facts exist. It is usually broken down into three specific positions:

A. Moral Relativism (Cultural or Individual)

This is the most common alternative view. It holds that moral statements can be true, but only relative to a specific standpoint.

• The Core Belief: "Killing is wrong" is true for us because our culture says so, but it might be "right" for a different culture (e.g., the Aztecs practicing sacrifice). There is no "God's eye view" to say which culture is correct.

• Analogy: Etiquette or Law. Driving on the left side of the road is "right" in the UK but "wrong" in the US. Neither is objectively correct by the laws of physics; it depends on where you are.

B. Non-Cognitivism (Emotivism)

This view argues that moral statements aren't facts at all—they are expressions of emotion.

• The Core Belief: When you say "Killing is wrong," you aren't stating a fact. You are essentially screaming "Boo on killing!" or expressing a negative feeling. It is neither true nor false; it is just an emotional outburst or a command.

• Analogy: Cheering for a sports team. Yelling "Go Team!" isn't true or false; it's an expression of support.

Error Theory (Moral Nihilism)

This is the skeptical view that moral talk is trying to state facts, but it always fails because moral properties don't exist.

• The Core Belief: "Killing is wrong" is a false statement. But "Killing is right" is also a false statement. Morality is a fiction we invented, like witches or unicorns.

• Analogy: Atheism regarding mythology. If someone asks, "Is Zeus stronger than Apollo?", the Error Theorist says, "Neither, because Greek gods don't exist."

Quick Comparison Table

View	Are moral claims True/False?	Is morality objective?	"Murder is wrong" means...
Moral Realism	Yes	Yes	"It is an objective fact that murder is wrong."
Moral Relevatism	Yes	No (Relative)	"My culture/society disapproves of murder."
Non Cognitivism	No	No	"Murder? Boo! Don't do it!"
Error Theory	No (All false)	No	"We made up the concept of 'wrongness'; it doesn't exist."

"Soft" Realism (The Middle Ground)

True because we prove/construct them; yes, but

There is a nuanced view often called Constructivism (associated with philosophers like Kant). It argues that morality is "constructed" by human reason. It isn't a floating physical fact like an atom (Anti-Realism), but because all rational humans must agree on it to function, it acts as if it is objective (Realism).

The "Hard" Realist View (Metaphysical Objectivity)

Morality is objective because it exists independently of human minds, like a rock, a planet, or a law of physics.  If all humans vanished tomorrow, the fact "Murder is wrong" would still float around the universe, just like the law of gravity would.

The "Soft" Realist / Constructivist View (Rational Objectivity)

Morality is objective because it is the necessary outcome of correct reasoning. It doesn't exist "out there" like a rock; it exists like a math proof. If all humans vanished, morality would vanish (because there are no minds to reason). However, as long as rational minds exist, there is only one correct answer to moral questions.

It's still objective, since it's not a matter of opinion or culture. If you disagree with a moral fact, you aren't just different you are irrational. You have made a logic error.

Conclusion

Metaethics reveals that the way we frame our moral language directly dictates what those morals can actually accomplish. If morality is purely subjective, ethical disputes reduce to matters of personal taste or cultural etiquette; if it is objective, moral progress is real and wrongdoing is a factual error, not just an unpopular opinion. Whether you view morality as an independent metaphysical truth, an inescapable demand of human reason, or a useful human invention, clarifying your metaethical foundation is the essential first step to making sense of right and wrong.

The Infinity Equivocation: Vicious vs. Benign Regress in Apologetics

Borrowing from Nowhere: Why the Universe Cannot Have an Infinite Past

Introduction

When defending the Kalam Cosmological Argument or the Prime Mover, defenders frequently encounter a common objection: "If numbers can stretch backward into infinity, why can't the history of the universe do the same?"

This counter-argument hinges on an equivocation fallacy—treating every kind of infinity as functionally identical. In philosophy and logic, there is a fundamental distinction between a benign infinity (an abstract, harmless mathematical sequence) and a vicious infinity (a dependent chain of physical causes that prevents an outcome from ever occurring). Confusing the two treats a mathematical concept on paper as if it were a physical bridge across time.

The Domino Analogy: An Endless Falling Line vs. A Static Ruler

Benign Infinity (The Static Number Line): Imagine an infinitely long measuring tape or a number line stretching left into negative infinity. Every number simply sits at its assigned coordinate. The number 10 doesn’t wait for -1,000,000 to be counted before it can exist; the entire structure is static, abstract, and present all at once. Nothing is waiting on a prior action to happen.

Vicious Infinity (The Falling Dominoes): Now imagine an infinite line of falling dominoes stretching backward into eternity, where today is the final domino falling. For today's domino to fall, the one before it had to fall, and the one before that, ad infinitum. If the chain of topples has no first domino to kick off the sequence, the chain reaction could never have started—meaning the domino representing "today" could never fall.

Numbers on a ruler coexist without causing one another (benign). Physical events must sequentially cause the next event to occur in time (vicious).

The Fatal Confusion: Equating the two is like looking at an endless ruler and concluding you could physically finish walking an infinite road to get home today. Abstract infinite sets can exist on paper, but a dependent, sequential task requires a starting point to ever reach the present

Infinity means endlessness, boundlessness, or something larger than any number, representing unlimited space, time, quantity, or extent, symbolized by ∞. It signifies a concept of "without end," applying to vast physical scales like the cosmos or abstract ideas like eternal cycles, and is used in mathematics for values beyond any finite number.

The Vicious vs Benign Infinity is useful to point out to critics who try to attack the first premise of the Kalam Cosmological Argument (KCA) - "Whatever begins to exist has a cause" or Prime Mover Argument, by trying to invoke an infinite regress. 

They will invariably attempt to point out a mathematical infinity/regress similar to (2) below and attempt to infer that it applies to (1) below. But this is the equivocation fallacy - is a logical error where a single word or phrase is used with different meanings in the same argument, making it seem valid when it's not. This is done by shifting meaning from one premise to the conclusion. Like using "right" to mean "entitled" in one part and "moral" in another. 

 

1. Vicious Infinity (The "borrowing money" analogy)

A vicious infinity, or vicious infinite regress, describes a situation where a task or object cannot exist because it depends on an infinite number of prior steps being completed first. Since an infinite number of steps can never be completed, the final result should not exist. If it does exist, the explanation leads to a logical contradiction.

• The money analogy: "It’s like a chain of people borrowing money from each other... if Darren pays Evan $10, and Darren got the $10 from Charlie... so on into infinity, no one actually took the money out of their pocket to start with, Evan never get paid."

• Why it is "Vicious": Because the payout depends on a source that never arrives. The chain has no foundation, so the event (Evan getting paid) is impossible. In the context of the universe, this argues that if the past were infinite, we would never have arrived at "today."
  

2. Benign Infinity (The "Fibonacci" analogy)

A benign infinity is an infinite series that exists conceptually or mathematically but does not prevent the current reality from existing. It often applies to abstract concepts (like math) or situations where the current step doesn't require the completion of the infinite series to exist.

• The Fibonacci sequence as an example: "There are still logically consistent continuations of the Fibonacci sequence that extend it all the way to negative infinity."

• Why it is "Benign": Because the number 10 doesn't "wait" for the negative infinity numbers to be counted before it can exist. The numbers are abstract and exist simultaneously. The regress is just a property of the number line, not a barrier to the existence of the number.

Summary Comparison

Feature	Vicious Infinity	Benign Infinity
Core Problem	Lack of foundation or starting point.	Infinite quantity without functional issues.
Causality	Dependent: Step B cannot happen until Step A finishes.	Independent: Steps typically exist abstractly or simultaneously.
Result	The event never happens (Logical Absurdity).	The concept is valid (Logical Consistency).
Example	An infinite chain of borrowers; no one ever gets paid.	The negative integers (... -3, -2, -1); they just exist.

Conclusion

Mathematical infinity allows negative integers to exist simultaneously without needing to be physically counted, making it entirely benign. In contrast, physical reality requires causal succession: today cannot arrive until yesterday has finished, and yesterday cannot finish until all prior days have elapsed.

An infinite causal past is a vicious regress—a loan with no original lender, a check that can never clear. Recognizing this distinction dismantles the attempt to use mathematical abstractions against cosmological realities, reaffirming that a dependent universe must ultimately rest upon an uncaused First Cause.

Moral Realism - Objective Morality Is Unavoidable

The Yardstick of Reality: The Logical Case for Moral Realism

Introduction

We readily agree that mathematics and physical laws exist independently of human opinion - 2 + 2 = 4 whether anyone believes it or not. Yet when it comes to morality, modern culture often retreats into relativism, reducing profound ethical truths to mere taste, social conditioning, or cultural convention.

Moral Realism cuts through this skepticism by making a straightforward claim: objective moral facts exist, and they remain true regardless of what any individual, majority, or culture believes. Far from being an outdated intuition, the existence of mind-independent moral truths is the only coherent foundation for logic, science, and human progress.

The concept of Moral Realism is the philosophical position that morality is objective, much like science or mathematics. It holds that there are moral facts about the world that are true regardless of what anyone thinks, feels, or believes.

This view contrasts with Anti-Realism (which claims morality is subjective, culturally constructed, or fictitious) and Non-Cognitivism (which claims moral statements are just expressions of emotion, like booing or cheering).

The Core Concept

To be a moral realist, one must generally accept three pillars:

1. Cognitivism: Moral statements (e.g., "Murder is wrong") express beliefs that can be true or false. They are not just emotional outbursts.
2. Truth-Aptness: These moral beliefs describe facts. "Murder is wrong" is capable of being true in the same grammatical way that "The cat is on the mat" is true.
3. Objectivity (Independence): The truth of these facts does not depend on the observer's opinion. If the entire world believed that torturing innocents was "good," the moral realist would argue that the entire world is simply mistaken, just as if everyone believed the earth was flat.

Here is the robust defense of Moral Realism, structured by its strongest arguments.

---

1. The "Companions in Guilt" Argument

This is arguably the strongest logical defense of moral realism. It argues that if you attack moral facts for being invisible or non-physical, you inadvertently destroy other things we believe are real, like mathematics and logic. This is essentially a philosophical strategy of mutually assured destruction. It defends Moral Realism by asserting that the arguments used to kill off morality would also accidentally kill off mathematics and logic—two disciplines that almost everyone (including skeptics) believes are objective and true.

Critics say moral facts (like "murder is wrong") are weird because you can't touch them or put them in a test tube. Since You cannot touch "wrongness." It isn’t made of atoms. it cannot exist. Since we can’t see/touch them, how do we know them? We must rely on "intuition," which skeptics claim is unscientific.

The Defense: You also cannot touch or see the number 7, or the logical rule of Modus Ponens, or the concept of validity. Yet, we believe 2+2=4 is an objective fact, not just an opinion. Thus, If mathematical truths can exist without being physical objects, why can't moral truths? To reject moral realism because it isn't "physical" forces you to reject mathematics and logic. If you want to keep math, you have to allow room for non-physical objective truths (companions)

2. The Argument from Epistemic Norms

Epistemic norms are the rules and standards that govern how we form, maintain, and revise our beliefs. While moral norms tell you how to act (e.g., "don't steal"), and prudential norms tell you what is in your best interest (e.g., "eat healthy food"), epistemic norms tell you how to be a "good thinker." They are strictly concerned with truth, knowledge, and justification.

• You ought to believe p only if p is true.
• You ought to proportion your belief to the strength of your evidence
• You ought not believe both p and not-p at the same time.
• You should only tate as fact that which you know.

This version is arguably stronger because it focuses on Normativity (rules about what you ought to do). It is largely associated with philosopher Terence Cuneo and his book The Normative Web.

The Attack on Morality

Skeptics argue that "Ought" statements are not real facts. The universe just is; it contains atoms and energy. It does not contain instructions on what you should do. Therefore, moral "oughts" (e.g., "You ought not kill") are just human inventions or emotions.

The "Guilt" of Logic

The fact is Logic and Science are entirely built on "ought" statements. These are called Epistemic Norms (norms of belief).

• If you believe P and you believe P > Q, logic dictates that you ought to believe Q.
• If you see overwhelming evidence for a theory, you ought to believe that theory is likely true.
• You ought not believe that A and non-A are both true at the same time.

If the skeptic says, "There are no objective 'oughts' in the universe," they fall into a trap:

• If there are no "oughts," then there is no rule saying I ought to accept their argument, even if it is valid.

• If they say, "But my argument is the best explanation, so you should accept it," they are appealing to a binding, objective norm (a logical "ought").

• Therefore, to argue against moral norms, they must utilize epistemic norms. They are proving that objective norms exist in the very act of trying to disprove them

Thus, one cannot do Science without Morality (or at least, normative facts).

The "Companions in Guilt" argument forces the skeptic to choose between two uncomfortable positions:

Position	Consequence
Accept the Companions	If you admit that Math and Logic are objective, non-physical realities, you lose your main reason for rejecting Morality. You have opened the door to "abstract objective truths."
Reject the Companions	If you bite the bullet and say "Okay, Math and Logic are not objectively true either," you destroy your ability to reason or make scientific arguments. You end up in total Nihilism.

3. The Argument from Moral Progress

This one of the most intuitive and historically grounded defenses of Moral Realism. It posits that the undeniable improvement in human morality over time (e.g., the abolition of slavery, the recognition of women's rights) cannot be logically explained unless there is an objective moral standard we are discovering.  

Here is an expanded analysis of how this argument works, why it is powerful, and how it defends itself against skeptics.

The "Yardstick" Analogy.

The argument rests on a simple logical rule: To say something has "improved," you must measure it against a fixed standard.

Imagine you are trying to determine if a child has grown taller. You cannot just compare the child to themselves from yesterday (too small a change) or to a cloud (which keeps moving). You need a ruler (a fixed standard). If there is no ruler, you can only say the child has changed, not that they have grown.

If Moral Realism is false, there is no "moral ruler. A Relativist can say, "*We used to like slavery; now we dislike it.*" They can describe the change. But they **cannot** say, "*We are better now.*" To say we are better implies we are closer to the "correct" answer than our ancestors were.  So the question to relativists is "is society better without slaves"? 

Almost everyone believes that abolishing chattel slavery was a genuine improvement, not just a random change in fashion (like switching from bell-bottoms to skinny jeans). The moment you admit it was better, you implicitly admit there is an objective standard of "Good" that slavery failed to meet.

Historical Evidence: The Phenomenon of "Convergence"

Realists argue that moral history does not look like random drift; it looks like scientific convergence.

In science, we started with many different theories (alchemy, humors, flat earth). Over centuries, scientists from different cultures converged on a single truth (chemistry, germ theory, round earth) because they were all studying the same objective reality

Realists argue morality shows a similar pattern.  Ancient cultures were vastly different (some sacrificed children, some had slaves, some were warrior castes). Over millennia, the world has slowly converged on specific values: Human Rights, equality, and the reduction of unnecessary suffering.

Realists argue that this convergence is best explained by the fact that we are slowly discovering the same moral facts, just as we discovered the same physics facts.

One of the most powerful formulations of this argument comes from philosopher Peter Singer.  Singer observes that moral progress almost always follows a specific direction: the expansion of the circle of moral concern.

• Primitive: "Only me and my kin matter."
• Tribe: "Only my tribe matters; strangers can be killed."
• Nation: "Only my countrymen matter."
• Humanity: "All humans matter (Universal Declaration of Human Rights)."
• Future: "Animals and future generations matter."

If morality were just random cultural "drift," we might expect the circle to shrink sometimes and expand others randomly. The fact that it consistently widens suggests a directional discovery process: we are realizing that the boundaries we drew were arbitrary errors.

4. Defense Against Skeptics

Skeptics (Anti-Realists/Evolutionary Debunkers) try to debunk this argument by saying we didn't abolish slavery because it was "objectively wrong." We abolished it because free markets were more efficient, or because cooperation helped us survive better. "Progress" is just "better adaptation," not moral truth.

However, this ignores the reasons people actually gave. When the British ended the slave trade, they did so at massive economic cost to themselves. It wasn't efficient; it was expensive. The people fighting for it didn't say, "This is inefficient." They said, "This is evil."

If we explain away progress as just "economic adaptation," we have to believe that every great moral reformer (Gandhi, King, Wilberforce) was deluded about their own motivations. Realism takes their insights seriously.

Skeptic's also argue that Realists are just biased - *You think the present is "better" because you live in it. If the Nazis had won, they would call their world "progress.*

But, we can objectively demonstrate incoherence in past moralities. The American Founders wrote "*All men are created equal*" but owned slaves. This is a logical contradiction.

Progress happened because we fixed the contradiction (we realized "All men" must include Black men, and women).

The Nazis were objectively wrong because their ideology relied on false scientific claims (e.g., that Jews were biologically inferior). Real moral progress is often the result of better reasoning and removing logical contradictions, which is an objective process.

The Argument from Moral Progress is the Realist's strongest emotional and historical weapon. It forces the skeptic into an uncomfortable corner:

To deny Moral Realism, you must be willing to look at the Holocaust, Slavery, and Apartheid and say, "*We didn't solve these because they were truly wrong; we just changed our minds, and our current view is no more 'true' than the views of the slaveholders.*"

If morality were just subjective taste (like preferring chocolate to vanilla), we couldn't say abolishing slavery was "better"—only "different." We would have to admit that a slave-owning society is just as valid as a free one, merely "different flavors."

Our strong intuition that we have improved as a species implies there is a standard (a "moral yardstick") we are measuring ourselves against. Realism is the only view that allows for the concept of genuine progress  Most people find that conclusion impossible to live with, which drives them back toward Realism.

5. The "Euthyphro" Defense (Independence)

The "Euthyphro" Defense is a crucial strategic move by Moral Realists. It borrows its name from one of Plato’s most famous dialogues, the Euthyphro, to argue that Moral Realism is the only ethical framework that prevents morality from becoming a tool of tyranny.

This defense essentially argues that if you reject objective, independent moral facts, you accidentally embrace a world where "Might Makes Right."

1. The Original Dilemma (Plato)

To understand the defense, you first need the context of the dilemma Plato presented in the Euthyphro. Socrates asks Euthyphro a deceptively simple question about the nature of "piety" (or "the good"):

"Is the pious loved by the gods because it is pious, or is it pious because it is loved by the gods?"

This creates a fork in the road for how we define Goodness:

Horn 1 (Independence/Realism): Goodness is independent. God (or society/law) loves it because it is already good.

Horn 2 (Voluntarism/Subjectivism): Goodness is dependent. It becomes good simply because God (or society/law) decides it is.

The Realist argues that if you choose the second option (that morality is created by a mind, whether God's or the Majority's), you destroy the meaning of morality itself.

The Arbitrariness Problem

If morality is merely "what the powerful say it is" (Horn 2), then the rules are arbitrary. If the majority commanded us to torture innocent children for fun, would that become morally good?

If you say "Yes," you have admitted that morality has no actual content; it’s just blind obedience. "Good" loses its meaning and just means "what I was told to do."

Realists say, "No, even if God commanded that, it would still be wrong." This proves there is a standard of Right and Wrong above the commander. This standard is the "Moral Fact" (Realism).

If Moral Realism is false, then morality is likely a construct of society.

Imagine a totalitarian government passes a law that legalizes genocide against a minority group. The majority of society supports it.

The Non-Realist Dilemma: If morality is defined by "society's agreement" or "the law," then by definition, the genocide is now morally right in that country. A non-realist has no platform to stand on and say, "This law is wrong." They can only say, "I personally don't like it."

The Realist Defense: Realism allows you to say: "The Law says X, and Society agrees with X, but X is objectively WRONG." This separates Power from Rightness. It gives the dissenter (the Martin Luther King Jr., the Sophie Scholl) the metaphysical ground to stand against the entire world and declare the world mistaken.

Who defines "Good"?	Consequence
The Subject / The State	"Might Makes Right." If the Nazis win and brainwash everyone, they become "morally right."
Reality Itself	"Right Makes Might." Even if the Nazis win, they are objectively wrong. Truth exists independently of power.

Finally, Moral Realism offers the most robust defense against authoritarianism.

If morality is created by minds (Subjectivism) or by society (Relativism), then the majority is always right. If 51% of a society votes to exterminate a minority, and morality is defined by that society, then the extermination is "morally right" by definition.

Moral Realism provides the only coherent ground to stand up and say, "The King is wrong," "The Law is wrong". It's the only philosophical shield that protects minorities and dissenters from the tyranny of the majority opinion.

Summary of the Defense

Argument	The Defense in a Nutshell
Companions in Guilt	If you deny moral facts, you must deny Math and Logic too.
Epistemic Norms	Science relies on "oughts" (rules of reasoning). If "oughts" aren't real, Science collapses.
Moral Progress	We have improved (e.g., ending slavery). Progress requires an objective standard to measure against.
Euthyphro	if you reject objective, independent moral facts, you accidentally embrace a world where "Might Makes Right."

Conclusion

Denying moral realism forces us into an unlivable intellectual corner. If morality is merely a subjective construct, we lose the ability to call atrocities like slavery or genocide objectively wrong, reducing the fight for human dignity to a clash of arbitrary preferences.

By grounding ethics in objective reality alongside logic and mathematical truth, Moral Realism provides the essential yardstick for genuine progress. It gives the individual dissenter the authority to stand before a corrupt majority and declare not just "I disagree," but "You are mistaken."

Atheism Defintion

How Atheism Shifted from "No God" to "No Belief"

Introduction

Ask an academic philosopher what "atheism" means, and you will get a very different answer than if you ask an online secular debater. For centuries, atheism was straightforward: a positive metaphysical claim asserting that God does not exist. Today, however, popular culture widely treats atheism as merely a passive "lack of belief."

This linguistic shift was neither accidental nor ancient; it was a calculated pivot to reframe the burden of proof in the debate over the existence of God.

For a significant portion of history, the standard definition of atheism was specifically the positive assertion that "God does not exist".

While many modern atheists define the term as a simple "lack of belief" (a psychological state), this is a relatively recent shift in the word's primary usage.

Here is the breakdown of how the definition has evolved from "denial" to "lack of belief."

1. The Historical Definition (16th–Mid-20th Century)

From its entry into the English language (via the French athéisme) in the 16th century until the mid-20th century, atheism was almost exclusively defined as the specific metaphysical claim that there is no God.

Academic Standard: In philosophy, atheism was traditionally viewed as the mirror opposite of theism. If theism was the proposition "God exists," atheism was the proposition "God does not exist."

The Agnostic Distinction: Because "atheist" was seen as a claim of knowledge (asserting a negative), it was distinct from "agnostic." In the late 19th century, Thomas Henry Huxley coined the term agnosticism specifically to describe people who "lacked belief" but refused to assert that God didn't exist because they felt the evidence was insufficient to claim either way.

2. The Shift: Antony Flew & The "Presumption of Atheism"

The definitions began to change significantly in 1976, when the philosopher Antony Flew wrote The Presumption of Atheism.

Flew argued that the burden of proof should lie with the believer. To achieve this logically, he proposed re-defining "atheism" not as a positive claim ("God does not exist") but as a negative state ("I do not hold a belief in God"). He explicitly admitted he was using the word in a new, "unusual" way to win a debate advantage. 

He wrote: "The word 'atheism', however, has in this contention to be construed unusually... I want the word to be understood not positively but negatively." This "negative definition" became incredibly popular among secular activists because it removed the burden of proof. If you are just "lacking belief," you don't have to prove anything, since this is just a statement about one's inner psychological state.

Note: Flew later rejected atheism ("there is no God" definition) and wrote There Is a God: How the World's Most Notorious Atheist Changed His Mind

Update:

"That was done to win a debate advantage", was not a quote, but that idea was in his book "The Presumption of Atheism" - 3rd chapter, 2nd paragraph. Here it is in full:

The word 'atheism', however, has in this contention to be construed unusually. Whereas nowadays the usual meaning of 'atheist' in English is 'someone who asserts that there is no such being as God', I want the word to be understood not positively but negatively. I want the originally Greek prefix 'a' to be read in the same way in 'atheist' as it customarily is read in such other Greco-English words as 'amoral', 'atypical', and "asymmetrical'. In this interpretation an atheist becomes: not someone who positively asserts the non-existence of God; but someone who is simply not a theist. Let us, for future ready reference, introduce the labels 'positive atheist' for the former and 'negative atheist' for the latter. What the protagonist of my presumption of atheism wants to show is that the debate about the existence of God ought to be conducted in a particular way, and that the issue should be seen in a certain perspective. His thesis about the onus of proof involves that it is up to the theist: first, to introduce and to defend his proposed concept of God; and, second, to provide sufficient reason for believing that this concept of his does in fact have an application. 

Here is a PDF of Chapter 3 - The Presumption of Atheism. The only way Flew could achieve his goal was to turn atheism from a claim into a non-claim.

3. The Current Split

Today, you will encounter two different definitions depending on who you are talking to:

• In Philosophy: Most academic encyclopedias (like the Stanford Encyclopedia of Philosophy) still define atheism as the view that there are no gods. They typically use the term "non-theism" for the broader lack of belief.

• In Public Discourse: Most self-described atheists and activist groups (like American Atheists) use the broader definition: "A lack of belief in gods."

To bridge this gap, people now often use qualifiers:

• Negative/Weak Atheism: Lacking belief (closer to the modern definition).

• Positive/Strong Atheism: Asserting God does not exist (the historical definition).

Short Video


Conclusion

The evolution of "atheism" from a positive assertion of fact to a passive psychological state has fundamentally altered modern apologetics. While the "lack of belief" definition offers secular debaters tactical cover against bearing a burden of proof, it flattens the distinction between active rejection and mere agnosticism.

Whether one adopts the classical metaphysical definition or the modern psychological one, shifting the vocabulary does not eliminate the underlying question: which worldview best explains the reality of the cosmos?

Is the Argument from Reason is Too Successful For its Own Good?

 A Redditor tried to refute the Argument From Reason. I'll examine it here.

The Reddit post will be presented here in italics. 

Thesis: the argument from reason mistakenly applies a general doubt about the validity of reason to the specific case of naturalism, but in reality applies equally to supernaturalism, as well as any other account of the universe, theistic or not. Therefore, it is not a relevant argument in discussions of theism.

TL;DR

The argument from reason states that naturalism (the view that only the natural exists and the supernatural does not) depends on reason, but makes it impossible to trust that same reason. On this grounds, it rejects naturalism. However, it is impossible to trust reason under any worldview, including theism. This has nothing to do with naturalism - it's just a feature of reason. Therefore, the argument from reason, if successful, succeeds at rejecting all worldviews (including the claim that the argument from reason itself is valid). So the argument from reason contradicts itself and must fail.

The Argument from Reason

The argument from reason is an argument associated with Christian apologist C. S. Lewis and popular with online Christian apologists in general (though it does not relate to Christianity specifically). The argument seeks to disprove a view of the universe called "naturalism", which basically holds that only natural things and the relationships between them exist, and that the supernatural doesn't. Some versions of the argument also further try to prove supernaturalism or theism.

Here is C. S. Lewis's description of the argument from reason:

One absolutely central inconsistency ruins [the naturalistic worldview].... The whole picture professes to depend on inferences from observed facts. Unless inference is valid, the whole picture disappears.... [U]nless Reason is an absolute--all is in ruins. Yet those who ask me to believe this world picture also ask me to believe that Reason is simply the unforeseen and unintended by-product of mindless matter at one stage of its endless and aimless becoming. Here is flat contradiction. They ask me at the same moment to accept a conclusion and to discredit the only testimony on which that conclusion can be based.— C. S. Lewis, "Is Theology Poetry?", The Weight of Glory and Other Addresses

In simpler terms, the argument basically goes like this:

If we claim naturalism is true, then we and everything we are is the result of natural, mindless, non-rational forces acting without any purpose.

If we are the result of nonrational forces, there is no reason to think that they would produce humans with an ability to use reliable reason.

Therefore, we have no reason to trust our own reasoning, and so we can't trust the reasoning that led us to naturalism.

A common counterargument to this is to point to evolution. 

Evolution, the defender of natural logic will say, favors humans who can correctly reason over those they cannot! Therefore there is a reason to think mindless forces produced reliable reason in us! It is at this point the proponent of the argument from reason will usually smirk, and say, "Oh? And how exactly do you know evolution is true? Did you use reason to conclude that? Hohohoho!", pushing up their glasses as they gently stroke their signed copy of Mere Christianity.

The apologist's defense here is simple but quite impenetrable. Any counterargument you present to defend your naturally-created reason will be based on, you guessed it, reason. So any counterargument you make will be circular! You cannot use unreliable reason to show that same reason to be reliable!

My response:

 But they forget that in a naturalistic worldview, everything is the result of matter acting in accordance with the physical laws. Not the laws of logic. So, when the atheist cites "reason" or a "reasonable conclusion", it really just the result of an unintelligent, mindless, material process that follows the physical laws, not logic/reason. 

But what of the Theist? She is not bound by the natural or by the physical laws. Thus, that which constrains the atheist/naturalist brain does not do so to the Theist. The Theist is free from the bounds of the physical and can engage in critical thinking as governed by the laws of logic. - From my post on the Argument From Reason

Back to the Redditors argument: 

So, what are we to do? Do we give up and convert to theism post-haste? Instead, let's take a trip - in our favorite rocket ship - to visit Planet Populon.

Planet Populon

Planet Populon is a distant planet not so different from Earth. On it live a race on beings called the Popularians, who are little purple creatures with four arms and six toes on each foot. They are very similar to humans, save for one important difference: they are incapable of understanding the logical fallacy of appeal to popularity.

The appeal to popularity is a simple logical fallacy that says "because an idea is popular, it must be true." To us humans, it's easy to see why this is false. For example, it was once popular to think the earth was flat! In some places, it's popular to think that pineapple tastes good on pizza! And yet those things are obviously false.

But the Popularians are different from us. They are incapable of recognizing this as a fallacy. Whenever one of them begins to think about the problems or contradictions that arise from an appeal to popularity, a special gland in their brains immediately floods their minds with thoughts of the last sports-ball match they watched, and they stop thinking about logical fallacies. Thus, the Popularians never realize that an appeal to popularity is fallacious - they are convinced that it's a valid form of reasoning.

The Popularians, too, believe in God. In fact, they have a logical proof of God's existence, known as the populogical argument. It goes a little something like this: most Popularians believe God exists – therefore, God exists. It's a flawless argument, beautiful in its simplicity, so elegant and minimal that there's no room for logical errors to possibly slip in. Furthermore, for those crazies that question whether reason itself is valid, the Popularians have an answer! It's popular to think that if God exists, he would create the Popularians with reliable reason. And since it's popular, it must be true! So the Popularians' reason must be reliable.

But we, from the side, know there is an error in the populogical argument. The argument commits a logical fallacy - an appeal to popularity. This means the Popularians' reason is not reliable, God or no. But the very fact that their reasoning is unreliable makes them unable to find the flaws in their proofs of their reasoning being reliable!

The Point

So what's the point of our visit to Planet Populon? It's simple. How do we know we are not like the Popularians?

If our reason was unreliable, and there was some fallacy we were incapable of noticing or some rule of logic we were missing, then all of our arguments would be moot. No matter how hard we worked to prove that the sky is blue, or that God exists, or that our reasoning was reliable, it would be pointless, because the very reason we used to tell the good arguments from the bad would be misfiring. And there's no way to prove we'd know if this was the case - after all, to prove that, we need to assume reason is reliable in our proof! It is impossible to prove that reason is reliable, because you need to use reason to do so.

So what does this have to do with the argument from reason? Well remember, the argument from reason was an argument targeted at naturalism. It said that naturalism must be false, because it implies our reason can't be trusted. But the Popularians don't believe in naturalism, and their reasoning still can't be trusted! It turns out, you can never prove your reason is trustworthy. No matter your worldview, you must assume your reason is reliable in order to make any argument at all.

My response:

This is the flaw! The argument from reason doesn't say that "reason is unreliable", it states that "reason is unreliable under a naturalistic worldview".  And that's because a naturalistic brain is constrained by the physical laws. Every human action, including thoughts, is the result of the physical laws. The laws of logic play zero part in the thinking process.  

Redditor: This means that the argument from reason succeeds not just against naturalism, but against any worldview! For example, here's the argument again, but directed at theism this time.

If we claim theism is true, then we and everything we are is the result of supernatural, mindful, rational forces acting without any purpose.

My response: 

Strawman argument - a logical fallacy where someone misrepresents, exaggerates, or distorts an opponent's actual argument to make it easier to attack, creating a weak "straw man" version to knock down instead of the real, stronger position. Thus, appearing to win the debate without addressing the core issue. It's a deceptive tactic in debates, often involving oversimplification or taking words out of context, to make one's own stance seem superior.

I do not argue, nor do I know of any Christian who argues for a "supernatural, mindful, rational forces acting without any purpose"

Redditor:

'If we are the result of rational forces, there is no reason to think that they would produce humans with an ability to use reliable reason.

Therefore, we have no reason to trust our own reasoning, and so we can't trust the reasoning that led us to theism.

A theist might object and say, "of course we have reason to think rational forces would produce rational minds!" But this time we can smirk, push up our glasses, and say, "Oh? And how exactly do you know rational forces would produce rational minds? Did you use reason to conclude that?" Once again, any argument you use to show that human reason is reliable under theism is itself based on that same reason

Once again, any argument you use to show that human reason is reliable under theism is itself based on that same reason.

Notice a parallel here. It's quite reasonable to think that we can trust our reason under theism - after all, we can propose a simple mechanism for it (God made it that way). Just as before, it was quite reasonable to think that we can trust our reason under naturalism - after all, we can propose a simple mechanism for it (evolution made it that way). But in both cases, establishing these mechanisms relies on our reason, so ends up being circular. 

My response: 

Under a theistic worldview, human reasoning is not viewed as a mere evolutionary byproduct for survival but as a reflection of a divine mind.

In this framework, the ability to think logically is often treated as a "gift" or an "imprint" of the Creator, ensuring that the human mind is attuned to the structure of the universe. This perspective changes why we trust our thoughts and how we use them.

The central premise of theistic reasoning (particularly in the Abrahamic traditions) is the concept of Imago Dei - that humans are created in the "image of God."

Since God is viewed as the ultimate rational being (the Logos), creating humans in His image implies endowing them with a "spark" of that rationality. This gives humans the unique ability to step beyond instinct (like animals) and engage in abstract thought, mathematics, and moral judgment. We reason because we are "mini-reasoners" modeled after the "Great Reasoner."

In a theistic worldview, the laws of logic (like A cannot be non-A) are not arbitrary rules invented by humans, nor are they rules that God simply "decided" to create. Instead, they are believed to be reflections of God's own nature.

Because God is consistent and cannot lie or contradict Himself, the universe He created operates on consistent, non-contradictory laws. When humans use logic, they are not inventing a tool; they are discovering the fabric of reality. To reason correctly is to think God's thoughts after Him.

Since a rational God designed the human mind specifically to know and understand the world, then we have a valid reason to trust our cognitive faculties. We can assume that our logic maps onto reality because both were made by the same Author.

Contrary to the popular cultural idea that faith and reason are opposites, the classical theistic view (championed by figures like Thomas Aquinas and Augustine) sees them as partners. It's actually atheism/naturalism v reason that are opposites, or incompatible. 

"Faith Seeking Understanding": This famous Latin phrase (fides quaerens intellectum) suggests that faith is the starting point that orients the mind, while reason is the tool used to explore and understand that faith.

 Theists often describe two sources of knowledge:

1. The Book of Scripture: Specific revelation (moral laws, nature of God).

2. The Book of Nature: General revelation (science, physics, logic). Since both books have the same Author, theists believe they cannot ultimately contradict each other. If they seem to, it is presumed that our human interpretation of one (or both) is wrong.

Theistic worldviews also offer an explanation for why human reasoning fails (bias, error, delusion). This is often called the "noetic effect of sin" or human finitude.

While the capacity for reason is divine, the execution is flawed because humans are imperfect/fallen.

Summary: The Difference

Feature	Naturalistic View	Theistic View
Origin of Reason	Evolutionary adaptation for survival.	Imprint of the Divine Mind (Imago Dei).
Basis of Logic	None. Thoughts are the result of physical laws not  logical laws..	Reflection of God's internal consistency.
Why Trust It?	Can't as it works for survival, not truth seeking	It was designed to find Truth.
Goal	To adapt and survive. Logic/truth not relevant.	To know God and understand His creation/reality.

Redditor: This is just how reasoning works. You can't use reason to prove itself, because reason itself precludes it. Reason an axiom - you must assume it to use it. But I'd say it's a pretty reasonable assumption to make.

Conclusion

The argument from reason is too successful. It's an example of a class of arguments I've witnessed more and more in recent years, that I call "sinking canoe" arguments. The name comes from the following story:

Two men are sitting in a canoe. Suddenly, a leak springs in the bottom of the canoe, and it begins to fill with water. The man in the back stands up, walks to the front, carefully examines the other man's seat, and declares: "Yep! Your half is sinking!"

The format of the fallacy is much like the argument from reason. Let's say you believe in idea A, and want to refute some competing idea B. Take a general issue that plagues both A and B, change up some wording and introduce some terminology to make it seem specific to B, and then present it as a refutation of B. These arguments are so very effective because to refute the specific argument against B usually seems impossible, because it's not an argument against B at all. What really must be done is to see the argument for what it is: a general issue that rests on a deeper level than the contest between A and B, and that supports them both – an issue that must be resolved before either A or B can succeed, or must refute them both, but that offers no insight into which of A or B is the better idea. The canoe sinks for us both, and we must either patch it together, or both go down with the ship.

My Response: 

The only axiom is Reason is the basis for knowledge

The argument from reason is too successful vs atheism/naturalism, not Christian theism. 

I'm sorry to tell you, but we are not sitting in the same boat. Since your naturalism cannot account for or give grounding to reason, critical thinking, or logic. However, God can. 

So yes, your boat is sunk, not the Christian's!

TL/DR

• The Redditor's Argument: The Argument from Reason claims that naturalism undermines trust in human rationality because naturalism treats thought as a product of mindless forces. However, the Redditor argues this issue applies to all worldviews - including theism - because any attempt to prove that human reason is reliable relies on reason itself, creating circular logic (illustrated by the "Planet Populon" thought experiment). Thus, the argument fails by being a "sinking canoe" that refutes all worldviews equally.

• The Counter: The Argument from Reason specifically targets naturalism, where thoughts are driven purely by physical laws rather than logical ones. Under Christian theism, human rationality is grounded in the Imago Dei (being made in the image of a rational God). Because human reason and the laws of logic reflect God's nature, theists have a valid foundation to trust human reason rather than trapped in circularity.

Conclusion

Naturalism fails because it cannot adequately account for or ground logic and critical thinking, whereas Christian theism provides a consistent foundation for human rationality. Ultimately, because the naturalistic worldview reduces every thought to physical reactions dictated purely by material laws, it destroys the very framework necessary to evaluate truth. By contrast, grounding logic in an inherently rational Creator allows theists to trust their cognitive faculties without falling into the trap of circular self-refutation.

Why Naturalists Can’t Trust Their Own Brains

Can Chemicals Think? Why Naturalism Destroys Its Own Logic

Introduction 

If philosophical materialism is true, every thought, conviction, and calculation you experience is ultimately reduced to electro-chemical reactions governed entirely by the non-rational laws of physics. But here lies the foundational paradox of the naturalist worldview: if your mind is merely a byproduct of unguided, physical processes, what rational justification do you have to trust that those physical processes produce truth? By reducing human rationality to mindless chemistry, naturalism pulls the rug out from under its own ability to argue, evaluate, and conclude anything at all.

Consider shaking a box of Scrabble tiles until letters spill onto the floor. If they happen to arrange themselves into a legible sentence—say, "It is raining outside"—you might recognize the letters, but you would never rely on that arrangement as a verified weather report. The sequence was dictated by friction, gravity, and kinetic impact, not by an awareness of the weather outside.

In the exact same way, if the neural firing in our brains is dictated strictly by physical laws and blind evolutionary pressure. Relying on our brains to discover transcendent truths about reality is no different than trusting randomly scattered Scrabble tiles to dictate philosophy.

The Core Syllogism

• Premise 1: If naturalism/materialism is true, all mental states (beliefs, judgments, inferences) are entirely determined by non-rational physical causes (neurochemistry, physics, evolutionary wiring).

• Premise 2: If mental states are entirely determined by non-rational physical causes, no belief is held on the basis of rational insight or objective logical grounding.

• Premise 3: A belief held without rational insight or logical grounding cannot claim rational justification.

• Conclusion: Therefore, if naturalism is true, no belief - including the belief in naturalism itself - can be rationally justified.

Survival vs. Truth: Natural selection acts exclusively on adaptive behavior, not metaphysical accuracy. As philosopher Alvin Plantinga famously demonstrated, evolution favors whatever neural wiring helps an organism survive, hunt, and reproduce. If a prehistoric human survived by falsely believing that every rustling bush was a demon rather than the wind, that false belief still preserved his life. Fitness only demands that adaptive actions occur, leaving cognitive reliability completely unguaranteed.

The Gap Between Causes and Reasons: A physical cause (a sodium-potassium pump firing in an axon) is fundamentally different from a logical ground (affirming that A = B and B = C; therefore, A = C). Physical events explain why something happens mechanistically, but they cannot confer logical validity. If naturalism is true, every philosophical conclusion - including atheism itself - is an involuntary physiological reaction, not an objective logical insight.

The Self-Defeating Loop: The materialist attempts to use logical deduction to establish that all thought is merely physical. Yet, if all thought is merely physical, that very deduction loses its authority as a rational act. As C.S. Lewis succinctly put it: "Unless I believe in God, I cannot believe in thought: so I can never use thought to disbelieve in God."

Why Natural Selection Cannot Rescue Reason

Materialists often argue that evolution bridges this gap by selecting for organisms with accurate brains. However, this conflates adaptive behavior with truth-tracking logic:

• Evolution operates exclusively on survival and reproduction (fitness). It selects for neural outputs that cause appropriate physical reactions, not for accurate metaphysical insight.

• A creature can survive equally well on falsehoods, provided the falsehood triggers the right physical response (e.g., fleeing a harmless rustle because it falsely believes a demon is there rather than a gust of wind).

• Even if evolution wires our brains to recognize basic immediate threats, it provides zero warrant for trusting our cognitive faculties when doing abstract philosophy, theoretical physics, or evaluating ultimate worldviews.

The Inescapable Self-Defeat

The naturalist arrives at materialism by constructing an argument: presenting evidence, evaluating premises, and inferring a conclusion.

Yet, if their conclusion is correct, the very process of formulating that argument was merely an involuntary cascade of physical reactions. The naturalist uses the authority of reason to dethrone reason, creating an inescapable epistemic circle.

The Theistic Grounding

Rationality requires that mind and reason are fundamental to the cosmos, not a freak accident of unguided particles. In a theistic framework:

• Objective logic and rationality originate in the supreme Mind (the Logos).

• Human beings possess rational faculties designed to apprehend objective truth and understand the universe.

• Reason is not an illusion generated by fizzing chemistry; it is a direct window into the rational order of reality.

Is the Argument from Reason is Too Successful For its Own Good?

The Big Bang’s Smoking Gun: Why the Universe Needs a Personal Creator

The Cosmological Argument

Introduction

For decades, modern materialism leaned on a comfortable assumption: the cosmos had simply always existed. But 20th-century astrophysics dismantled that safety net, replacing an eternal backdrop with a concrete cosmic birthday. If the universe had an absolute beginning, then matter, energy, space, and time were brought into being by a cause outside of themselves. Tracing the physics to its logical conclusion reveals that the initial catalyst could not have been an impersonal mechanical force, but a personal agent possessing free will.

To understand why the cause of the universe must be personal rather than a mindless physical law, consider the difference between water freezing and a person standing up:

• The Impersonal Process (Water Freezing): If the temperature drops below 0°C, liquid water freezes into ice automatically and immediately. Cause and effect are locked in an automatic chain. If the freezing temperature had existed from all eternity, the ice would also have existed from all eternity; you could never have an eternal cause suddenly produce a temporal ice cube out of nowhere.

• The Personal Choice (The Person Standing): Now imagine a person sitting quietly in a chair from eternity past. That person possesses volition and free agency. They can sit indefinitely, and then freely choose to stand up at a specific moment without any prior physical trigger pushing them.

An impersonal, eternal force produces an eternal effect. Only a personal agent with free will can exist eternally and choose to initiate a brand-new temporal event.

The Shattered Static Model: The Death of the Eternal Universe

In the early 20th century, physics rested on the assumption of a static, uncreated cosmos. If matter had always existed, materialists faced no burden to account for its origin.

• Einstein’s General Relativity (1915): Albert Einstein’s field equations pointed toward an unstable, dynamic universe that was either expanding or contracting.

• The Hubble Discovery (1929): Edwin Hubble analyzed galactic red-shifts and confirmed that galaxies are actively flying apart from one another in all directions.

• The Singularity: Rewinding cosmic expansion leads inexorably back to an absolute origin point—the Big Bang—roughly 13.8 billion years ago.

• The Borde-Guth-Vilenkin (BGV) Theorem (2003): Modern cosmology established that any universe with an average cosmic expansion rate greater than zero ($H_{av} > 0$) must have a past space-time boundary. The cosmos is not past-eternal.

The Materialist Trap: You Cannot Use Physics to Explain Physics

The Big Bang is not an explosion of matter inside pre-existing empty space; it marks the boundary where matter, energy, physical space, and time itself began.

• No Material Precursor: You cannot appeal to the laws of chemistry, gravity, or quantum mechanics to explain the origin of the cosmos, because those physical laws did not exist before the space-time manifold itself emerged.

• The Principle of Causality: Out of nothing, nothing comes (ex nihilo, nihil fit). A state of literal non-being possesses zero potentiality, zero causal powers, and zero properties.

• The Fallacy of Self-Creation: The universe could not cause itself, because that would require it to exist before it existed in order to do the causing.

 Deductive Profiling: The Blueprint of the First Cause

Because an effect cannot be identical to its cause, the entity responsible for bringing time, space, and matter into existence must transcend them entirely:

Cosmic Characteristic	Required Nature of the Cause	Logical Deduction
Space Came into Being	Spaceless (Non-spatial)	Cannot be physically extended or bounded within dimensions.
Time Came into Being	Timeless (Eternal)	Exists beyond the temporal sequence of past, present, and future.
Matter/Energy Began	Immaterial (Incorporeal)	Cannot consist of atoms, particles, mass, or mechanical forces.
Entire Cosmos Produced	Unimaginably Powerful	Capable of bringing the total energy of the universe into reality ex nihilo.

The Clincher: Why the Cause Must Be Personal

There are only two candidate entities in classical metaphysics that can be timeless, spaceless, and immaterial: abstract objects (such as numbers or mathematical sets) or an unembodied personal mind.

• Abstract Objects Are Causally Impotent: The number 7 or the concept of geometry cannot cause a single physical event in the real world.

• The Problem of the First Effect: If the cause were an unguided, mindless set of necessary and sufficient conditions, its effect would be co-eternal with it. An eternally existing physical mechanism cannot "wait" billions of years before deciding to activate.

• Volitional Agency: The only coherent explanation for how a temporal effect with a discrete beginning can emerge from an eternal, changeless state is libertarian free choice. A conscious agent decided to initiate a temporal reality.

---

The claim that the cosmos erupted out of pure nothingness without an external cause contradicts foundational principles of logic, reason, and empirical science. Tracing the universe back to its beginning yields a cause that is spaceless, timeless, immaterial, overwhelmingly powerful, and personal. Physics does not bury the theistic worldview; it leads straight to the doorstep of a Creator.
