In 30 secondsHarris is an American neuroscientist and author, one of the 'Four Horsemen' of the New Atheism. He rejects belief in God and judges religions by whether they help human flourishing. He argues that free will is an illusion and that the sense of a separate self is one too. He holds that science can say what is good, because morality is about the well-being of conscious creatures. He practises meditation and defends a spirituality without religion.
Key facts

Positions

Does God exist?God
AtheismTheism
Stated explicitly
Position

A leading voice of the New Atheism. He opposes dogmatic belief and debated Rick Warren (2007) and William Lane Craig (2011) on God and morality.

Why
What is objected, and the reply

The moral argument: without God, there would be no objective right and wrong.

Harris

He calls the idea that our morality comes from Christianity "one of these shibboleths of organized religion" that needs to be retired.

The kalam argument: whatever begins to exist has a cause, so the universe has a cause, and that cause is God.

No known reply from them.

Defends : The problem of evil

Is the mind more than matter?Mind and body
MaterialismDualism
Interpretation
Position

He takes the hard problem of consciousness seriously: consciousness is 'the fact that the lights are on', and 'the hard problem still stays hard'. He does not say the mind is a separate substance.

Are we truly free?Freedom
Determinism (no free will)Free will
Stated explicitly
Position

In Free Will (2012) he argues that free will is an illusion: our thoughts and choices come from causes we do not control. He says this does not destroy morality.

Why
What is objected, and the reply

Compatibilism: we are free in the sense that matters (acting on our own reasons), even if determinism is true.

Harris

He says most people think we must live with the illusion of free will or soften the talk about it, and argues that this is a mistake.

O
Objection

Without free will, moral responsibility and the law would collapse.

Harris

He says morality and law do not really depend on free will. He adds that giving up the belief is a direct antidote to hatred: with another life story, anyone could have been the murderer.

Criticizes : The only freedom worth wanting

What makes an action good?Basis of morality
Duty (deontology)Consequences (consequentialism)Character (virtue ethics)Other (divine law, relationships, value creation…)
Interpretation
Position

He bases morality on the well-being of conscious creatures. Critics such as Kwame Anthony Appiah say this amounts to a form of utilitarianism. In 2020 he said that helping others is 'the wiser form of selfishness' if you want to be happy.

Do good and evil exist objectively?Status of morality
Anti-realism (morality is human-made)Moral realism (objective moral truths)
Stated explicitly
Position

He rejects moral relativism: moral questions have better and worse answers, grounded in facts about human flourishing.

Why
What is objected, and the reply

You cannot get an "ought" from an "is": showing what helps societies does not show what we ought to want.

Harris

He says one only has to grant that a universe where everyone suffers as much as possible for as long as possible would be bad, by any measure of bad. Every step away from it is then better, and science can study such facts about conscious experience.

Persons are ends in themselves: adding up well-being cannot justify sacrificing one person for others.

No known reply from them.

Mixed : The drowning child: helping distant people is a duty, Turning the trolley: one death rather than fiveCriticizes : Reason is the slave of the passions: morality is felt, not demonstrated

Can reason judge everything, faith included?Faith and reason
Primacy of faith / the heartReason alone judges
Interpretation
Position

In The End of Faith he criticises belief held without evidence and judges religions by their effects on human well-being, not by their own authority. In 2021 he adds that errors in science are cured by more and better science, not by another way of knowing.

Why
What is objected, and the reply

Believing in God without proof can be rational: for many people, belief in God is a basic belief, like trusting memory or other minds.

No known reply from them.

On the big questions

Does God exist?Atheism

A leading New Atheist. In 2025 he finds a well-known atheist's conversion to Christianity unconvincing, because she gave no reasons for thinking the doctrine true.

Why
What is objected, and the reply

The moral argument: without God, there would be no objective right and wrong.

Harris

He calls the idea that our morality comes from Christianity "one of these shibboleths of organized religion" that needs to be retired.

The kalam argument: whatever begins to exist has a cause, so the universe has a cause, and that cause is God.

No known reply from them.

Defends : The problem of evil

The question on the site: all the arguments
Does life have a meaning?A meaning to create

In 2025 he says the point of our being here is to make life worth living, then to refine it and make human happiness more beautiful.

Why
The question on the site: all the arguments
Are we free?No free will

Free will is an illusion, he argues in Free Will (2012) and again in 2021: neither determinism nor randomness gives us free will.

Why
What is objected, and the reply

Compatibilism: we are free in the sense that matters (acting on our own reasons), even if determinism is true.

Harris

He says most people think we must live with the illusion of free will or soften the talk about it, and argues that this is a mistake.

O
Objection

Without free will, moral responsibility and the law would collapse.

He says morality and law do not really depend on free will. He adds that giving up the belief is a direct antidote to hatred: with another life story, anyone could have been the murderer.

Criticizes : The only freedom worth wanting

The question on the site: all the arguments
What makes something right?Consequences

Morality is about the well-being of conscious creatures.

Why
What is objected, and the reply

You cannot get an "ought" from an "is": showing what helps societies does not show what we ought to want.

Harris

He says one only has to grant that a universe where everyone suffers as much as possible for as long as possible would be bad, by any measure of bad. Every step away from it is then better, and science can study such facts about conscious experience.

The question on the site: all the arguments
Should we fear death?Nothing to fear

In 2021 he says one can just as easily argue that the transience of everything magnifies its beauty, rather than that death robs life of meaning.

Why
What is objected, and the reply
O
Objection

If death is the end of experience, that finality robs life of any purpose, meaning or significance.

Harris

He rejects this religious intuition: one could just as easily argue that it is the transience of everything that magnifies its beauty.

The question on the site: all the arguments
Who am I, really?No fixed self

In Waking Up he argues that the sense of self is an illusion, which meditation can reveal. In 2022 he says that seeing this illusion is the most important thing he has learned.

Why
The question on the site: all the arguments
Should we believe without proof?No belief without evidence

He criticises religious belief held without evidence (The End of Faith, 2004).

Why
What is objected, and the reply

Believing in God without proof can be rational: for many people, belief in God is a basic belief, like trusting memory or other minds.

No known reply from them.
The question on the site: all the arguments
Does history have a direction?Progress

He sees real progress, in knowledge and in how societies treat violence, but says it is not guaranteed: no law of history ensures things keep getting better, and the same power that improves life can destroy us.

Why
What is objected, and the reply

Progress is a storm: what looks like improvement piles up ruins behind it.

No known reply from them.
The question on the site: all the arguments

In their words

Neither determinism nor randomness, nor any combination of the two, justifies the feeling that most people have that goes by the name of free will.
There is no will in randomness.
Being able to experience the illusoriness of the self has been the most important thing I've ever learned in my life.
Consciousness is the fact that the lights are on.
3 more quotes
The facts tell us that free will is an illusion.
There's no will that's free from the universe.
The purpose of meditation is to truly wake up from the unhappy dream you call your life, not merely to lower your blood pressure.

  9. 2021Final thoughts on free will

    He restates his case: neither determinism nor randomness gives free will, and we only witness our decisions once they are made.

    In their words
    « the feeling of having free will is directly connected to the feeling of being a self »He ties the feeling of free will to the feeling of being a self. watch
    « neither determinism nor randomness, nor any combination of the two, justifies the feeling that most people have that goes by the name of free will »Neither determinism nor randomness, nor a mix, supports the feeling of free will. watch
    « There is no will in randomness. »Randomness would not give us free will: a random act would be out of character, not free. watch
  10. 2021The Paradox of Death

    In a solo episode he says one can just as easily argue that the transience of everything magnifies its beauty, rather than that death robs life of meaning.

    In their words
    « I think one could easily argue it's the treny of everything that magnifies the beauty of everything »He argues that the fleeting nature of things magnifies their beauty, so death does not rob life of meaning. watch
    « if death really is the end of us if it's synonymous with the end of experience well then that finality robs life of any conceivable purpose or meaning or significance »He presents and rejects the religious intuition that death as the end of experience would make life meaningless. watch
  11. 2022The illusion of the self

    With Jay Garfield he says that seeing the self is an illusion is the most important thing he has learned, and calls this insight a 'universal solvent' of psychological suffering.

    In their words
    « being able to experience the illusoriness of the self has been the most important thing i've ever learned in my life »He says seeing that the self is an illusion is the most important thing he has learned. watch
    « it is not there in the first place and it can be discovered its absence can be discovered in a way that changes the character of experience »He claims there is no self to begin with, and its absence can be directly seen. watch
    « this insight into selflessness is a kind of psychologically speaking a kind of universal solvent of psychological suffering »He calls the insight into selflessness a universal solvent of psychological suffering. watch
  12. 2023Free will: rival intuitions

    After a long exchange with Tim Maudlin, he says that certain rival intuitions about free will cannot be settled by argument alone; if you experience yourself in a certain way, some points cannot land.

    In their words
    « certain rival intuitions on the topic of Free Will can't quite be resolved through argument »After a long exchange with Maudlin on free will, he concludes that rival intuitions on the topic cannot be settled by argument alone. watch
    « if you experience yourself in a certain way certain points just can't land »He says that if you experience yourself in a certain way, some points about free will cannot land, and with a different experience they seem obvious. watch
  13. 2024The Moral Landscape clarified

    In a solo episode he restates that we know to a moral certainty that human life can be better, and compares our intuitive morality to intuitive physics: it may be wrong.

    In their words
    « we know to a moral certainty that human life can be better »He says we know with moral certainty that human life can be better, which grounds objective moral truths. watch
    « are members of the Islamic State wrong about morality yes really wrong yeah yes can we say so from the perspective of science yes »He says science can tell us that the Islamic State is really wrong about morality. watch
    « this paints an unrealistic picture of the human mind »He rejects Hume's view that moral truths can only move us when combined with some passion, calling it an unrealistic picture of the mind. watch
  14. 2025No free will, and compassion

    Talking with Dan Harris, he says nobody has free will and that giving up the belief is a direct antidote to hatred: with another life story, anyone could have been the murderer.

    In their words
    « I think being a pacifist is really just a way of outsourcing a real ethical consideration of violence to other people who are not pacifists »He argues that pacifism is a way of outsourcing the ethics of violence to others, and not a moral high ground. watch
    « my position on free will I actually don't think anyone has it and I think everyone is just kind of playing out the causes and conditions »He says nobody has free will: everyone is playing out causes and conditions such as genes, environment and neurochemistry. watch
    « I too could have been that person »He says that with another life story, genes and upbringing, anyone could have been a murderer, so compassion is possible even for the worst. watch
  15. 2026Consciousness and machines

    He defines consciousness as the fact that the lights are on. If AIs seem conscious, he says, people will treat them as conscious, and it is easier to assume that other humans are conscious than machines.

    In their words
    « consciousness is the fact that the lights are on. And it's synonymous with the fact of experience »He defines consciousness as the fact that the lights are on, i.e. experience. watch
    « there really couldn't be a Westworld because, you know, only psychopaths could go there »If AIs seem conscious, people will treat them as conscious, so a Westworld park could not exist. watch
    « it is parsimonious to assume every every one like us, you know, born Homo sapiens are are very likely conscious when they say they are »He says we can assume other humans are conscious, but it is hard to say the same of machines. watch
  16. 2026Today's language models

    He says he has no concern that current language models are conscious, while he already said in 2023 that we do not know when consciousness emerges and that AIs will come to seem conscious.

    In their words
    « there's simply no question that we have built intelligent machines and we're continuing to build them and they are intelligent »He says machines are already intelligent in the sense of competent, whether or not there is anything it is like to be them. watch
    « we simply don't know you know how and when Consciousness emerges and whether it comes along for the ride at a certain level of complexity »He says we do not know how or when consciousness emerges, or whether it comes with a certain level of complexity and intelligence. watch
    « at a certain point they're going to seem conscious and we're going to treat them as though they were conscious whether or not we ever know the ground truth there »He predicts that AIs will come to seem conscious and be treated as conscious, whether or not we ever know the truth. watch

Turning the trolley: one death rather than fivePhilippa Foot · What makes something right?Mixed

The same 2025 episode with David Edmonds covers 'trolleyology'. The page does not give his verdict.

The hard problem of consciousness and zombiesDavid Chalmers · Is the mind the brain?

In 2021 he tells Anil Seth he is 'taken in more by the so-called hard problem of consciousness'. Even without zombies, 'the hard problem still stays hard'.

What is it like to be a bat?Thomas Nagel · Is the mind the brain?

He uses Nagel's definition: consciousness is 'the fact that it's like something to be a system'.

Criticizes · 2
The only freedom worth wantingDaniel Dennett · Are we free?

Dennett defends a compatibilist free will and said Harris attacked only the popular idea. Harris answered with 'The Marionette's Lament' (2014).

Reason is the slave of the passions: morality is felt, not demonstratedHume · What makes something right?

Took part in the 2010 Nightline face-off on whether God has a future.

DDaniel KahnemanDisagrees

In 2020 he says they disagree: for him the remembering self is just a mode of the experiencing self.

Signature ideas

A science of morality

Some lives and societies are better than others, and this depends on facts about brains and the world. So he thinks values are open to scientific study; he answers the 'is-ought' objection by arguing that well-being is the base.

Spirituality without religion

Spiritual experience is real and valuable, he says, but it does not prove any religious claim. Meditation can show that the self is an illusion.
