“The unexamined life is not worth living.” – Socrates
Philosophy is essential for grappling with life’s biggest questions about existence, morality, and meaning. While not all atheists misunderstand philosophy, some atheists make errors in their critiques of theism or philosophical reasoning. Below are 15 common mistakes and why they fail to undermine belief in God.
1. Philosophy is Irrelevant in a Scientific Age
Some atheists dismiss philosophy as outdated, claiming that science alone provides truth. This argument overlooks the foundational role philosophy plays in every discipline, including science.
Daniel Dennett, an atheist philosopher, admits, “There is no such thing as philosophy-free science; there is only science whose philosophical baggage is taken on board without examination.”¹
Anticipating Objection:
- Objection: “Philosophy is unnecessary; science answers everything.”
- Response: Science explains the “how,” but philosophy addresses the “why.” Questions about meaning, morality, and existence fall squarely within philosophy’s domain.

2. Morality is Entirely Subjective
Atheists often argue that morality is a human construct with no objective basis. However, this view struggles to explain universal moral intuitions, such as the wrongness of murder or the value of compassion.
Philosopher William Lane Craig argues, “If God does not exist, then objective moral values do not exist. But objective moral values do exist; therefore, God exists.”²
Anticipating Objection:
- Objection: “Morality evolves with culture and has no objective basis.”
- Response: While moral practices may change, the existence of universal moral principles—such as justice or human dignity—points to a transcendent moral lawgiver.

3. The Burden of Proof Lies Solely on Theists
Some atheists claim that only theists bear the burden of proof in debates about God. This argument misunderstands the philosophical nature of atheism as a worldview that also requires justification.
Philosopher Alvin Plantinga states, “Both the theist and the atheist make claims about reality, and both are required to defend those claims.”³
Anticipating Objection:
- Objection: “Atheism is just a lack of belief, not a claim.”
- Response: Atheism implicitly denies the existence of God, making it a philosophical stance that requires evidence and argumentation to support its validity.
³ Alvin Plantinga, God and Other Minds: A Study of the Rational Justification of Belief in God (Ithaca: Cornell University Press, 1967).
4. The Euthyphro Dilemma is Irrefutable
Atheists often use the Euthyphro Dilemma to challenge theistic morality: Is something good because God commands it, or does God command it because it is good? This argument creates a false dichotomy.
William Lane Craig counters, “God’s nature is the standard of goodness, and His commands flow necessarily from His character.”⁴ Morality is neither arbitrary nor independent of God—it is grounded in His unchanging nature.
Anticipating Objection:
- Objection: “The Euthyphro Dilemma shows morality doesn’t need God.”
- Response: Grounding morality in God’s nature resolves the dilemma, avoiding arbitrariness and providing a coherent foundation for objective morality.

5. Free Will is an Illusion
Many atheists, especially materialists, argue that free will is an illusion caused by deterministic physical processes. This view undermines moral responsibility and rationality itself.
C.S. Lewis observed, “If the solar system was brought about by an accidental collision, then the appearance of organic life was also an accident… and all our present thoughts are mere accidents.”⁵ Theism affirms free will, recognizing humans as moral agents created in God’s image.
Anticipating Objection:
- Objection: “Free will doesn’t exist; our actions are determined by our biology.”
- Response: Theism allows for free will by recognizing the soul as distinct from the body, while materialism reduces humans to mechanistic beings.
⁵ C.S. Lewis, The Problem of Pain (New York: HarperOne, 1940).
6. Logic and Reason are Independent of God
Atheists often claim that logic and reason exist independently of any worldview. However, theism provides a coherent foundation for immaterial, universal, and unchanging logical laws.
Alvin Plantinga writes, “The laws of logic are grounded in the nature of God, who is the ultimate source of truth and rationality.”⁶
Anticipating Objection:
- Objection: “Logic is self-evident and doesn’t need God.”
- Response: The universal and immaterial nature of logic aligns with a transcendent Creator, whereas atheistic materialism cannot adequately explain their existence.
⁶ Alvin Plantinga, Warrant and Proper Function (New York: Oxford University Press, 1993).
7. The Problem of Evil Disproves God
The existence of evil is often presented as evidence against an all-good, all-powerful God. However, the argument presupposes an objective moral standard that atheism cannot justify.
C.S. Lewis noted, “My argument against God was that the universe seemed so cruel and unjust. But how had I got this idea of just and unjust? A man does not call a line crooked unless he has some idea of a straight line.”⁷
Anticipating Objection:
- Objection: “If God is good, why is there evil in the world?”
- Response: God allows evil to exist temporarily to achieve greater goods, such as human free will and the possibility of moral growth and redemption.
⁷ C.S. Lewis, Mere Christianity (New York: HarperOne, 1952).
8. Faith is Belief Without Evidence
Atheists often caricature faith as blind belief without evidence. However, this misrepresents both the biblical and philosophical understanding of faith.
Thomas Aquinas defined faith as “the assent of the intellect to what is divinely revealed,” which is grounded in reason and evidence.⁸ Faith in the Bible is trust based on evidence, such as eyewitness testimony (John 20:31).
Anticipating Objection:
- Objection: “Faith means believing something without evidence or proof.”
- Response: Faith is not opposed to evidence; it involves trust in what evidence supports. Christianity invites examination of its claims, as seen in Acts 17:11, where the Bereans examine Paul’s teachings against the Scriptures.
⁸ Thomas Aquinas, Summa Theologica.
9. Meaning Can Be Fully Constructed Without God
Some atheists claim that meaning and purpose can be entirely self-constructed. While subjective meaning is possible, it lacks ultimate significance in a godless universe.
Philosopher Friedrich Nietzsche, a staunch atheist, recognized the existential crisis this creates: “When one gives up the Christian faith, one pulls the right to Christian morality out from under one’s feet.”⁹ Without God, ultimate meaning and purpose dissolve into personal preference.
Anticipating Objection:
- Objection: “We can create our own meaning without needing God.”
- Response: Self-constructed meaning fails to answer why the universe exists at all or why human life has intrinsic value. Theism offers a transcendent purpose: glorifying God and enjoying Him forever.
⁹ Friedrich Nietzsche, The Gay Science (New York: Vintage Books, 1974).
10. The Cosmological Argument is Obsolete
Atheists often dismiss the cosmological argument, claiming it has been refuted or rendered unnecessary by modern science. However, this argument remains philosophically robust, particularly in its Kalam formulation:
- Whatever begins to exist has a cause.
- The universe began to exist.
- Therefore, the universe has a cause.
Philosopher William Lane Craig argues, “If the universe began to exist, then it must have a transcendent cause, which we understand to be God.”¹⁰ Modern cosmology supports the premise that the universe had a beginning, aligning with this argument.
Anticipating Objection:
- Objection: “The universe could have come from nothing without a cause.”
- Response: Philosophical and scientific reasoning both affirm that nothing comes from nothing. A transcendent Creator remains the most plausible explanation for the universe’s origin.
¹⁰ William Lane Craig, Reasonable Faith: Christian Truth and Apologetics (Wheaton: Crossway, 2008).
11. The Teleological Argument is ‘God of the Gaps’
Critics often dismiss the teleological argument (fine-tuning) as a “God of the gaps” explanation. This misrepresents the argument, which is based on empirical evidence, not ignorance.
Physicist Paul Davies remarked, “The impression of design is overwhelming.”¹¹ The fine-tuning of the universe’s constants and conditions points to intentionality and purpose, hallmarks of a Creator.
Anticipating Objection:
- Objection: “The multiverse explains fine-tuning without needing God.”
- Response: The multiverse hypothesis lacks empirical evidence and only pushes the question back: why does the multiverse itself exist and follow specific laws? Theism provides a more parsimonious explanation.

12. Consciousness Can Be Fully Explained by Materialism
Materialist atheists argue that consciousness is purely a product of physical brain processes. However, this fails to address the “hard problem” of subjective experience.
Philosopher David Chalmers writes, “Consciousness is an anomaly that stubbornly resists reduction to physical processes.”¹² Theism explains consciousness as part of being made in the image of God (Genesis 1:27).
Anticipating Objection:
- Objection: “Consciousness is just brain activity.”
- Response: While brain activity correlates with consciousness, it does not explain subjective experience or the immaterial aspects of thought and self-awareness.
¹² David Chalmers, The Conscious Mind: In Search of a Fundamental Theory (New York: Oxford University Press, 1996).
13. Atheism is the Default Position
Atheists often claim that atheism is the “default” position, requiring no justification. This argument confuses atheism (a claim that God does not exist) with agnosticism (a lack of belief either way).
Philosopher Peter Kreeft clarifies, “Atheism is not merely a lack of belief in God; it is a denial of the existence of God, which entails its own philosophical commitments.”¹³ Both atheism and theism require evidence and argument.
Anticipating Objection:
- Objection: “Atheism is simply a lack of belief.”
- Response: A lack of belief in God does not absolve atheism from addressing the deeper philosophical questions of existence, morality, and meaning.
¹³ Peter Kreeft, Handbook of Christian Apologetics (Downers Grove: IVP Academic, 1994).
14. The Universe is Self-Explanatory
Some atheists argue that the universe exists as a “brute fact,” requiring no further explanation. This view violates the principle of sufficient reason, which states that everything that exists must have a reason for its existence.
Philosopher G.W. Leibniz famously asked, “Why is there something rather than nothing?”¹⁴ Theism provides a coherent answer: the universe exists because it was created by a necessary being—God.
Anticipating Objection:
- Objection: “The universe just exists without explanation.”
- Response: A self-existent, necessary being (God) explains the universe’s existence better than the assertion that the universe itself is necessary or uncaused.
¹⁴ G.W. Leibniz, Monadology.
15. Atheism is Neutral
Atheists often present their worldview as neutral, free from bias or assumptions. However, atheism entails significant metaphysical claims about reality, morality, and meaning.
Alister McGrath writes, “Atheism is not a default position but a complex worldview that demands critical evaluation.”¹⁵ Theism offers a more comprehensive and coherent explanation of reality, addressing questions that atheism often overlooks.
Anticipating Objection:
- Objection: “Atheism doesn’t need a worldview; it’s just a rejection of God.”
- Response: Atheism still requires a framework for explaining existence, morality, and human purpose, which are deeply philosophical questions.

A Final Challenge to Atheism
Philosophy is essential for addressing life’s biggest questions. While atheism often dismisses theism, it struggles to account for logic, morality, consciousness, and existence itself. Could it be that the answers lie in the God who is the ultimate foundation of truth, meaning, and reason?
