John Lennox on AI as God, Science versus Atheism, and the Return to Theism
Oxford mathematician and philosopher of science John Lennox speaks with OCCA Oxford for the Veritas Forum on the cultural reversal underway in the science-versus-religion debate, the logical self-destruction of materialism, artificial intelligence as a God-surrogate, and why secular utopias fail to address the central human problem of guilt and forgiveness.
Key ideas
- The conflict is science versus atheism, not science versus religion. Materialism holds that the brain is the product of a mindless, unguided process — yet science requires trusting that brain to reason correctly. A computer generated by a mindless process would not be trusted in any lab; the same logic applies to the materialist’s own mind. The argument, drawn from CS Lewis and Alvin Plantinga, is that naturalism is self-refuting.
- ‘Le grand renversement’ — a cultural great reversal. Jordan Peterson, Tom Holland, and Ayaan Hirsi Ali have each moved from scepticism or active atheism toward Christianity, not despite their intellectual rigour but through it. The pioneers of science — Galileo, Kepler, Newton — were Christians who expected law in nature because they believed in a lawgiver.
- AI cannot be God because consciousness cannot be engineered. Materialism has no explanation for consciousness; without that, any claim of machine consciousness is empty. The danger is not a technological god but a cultural one: AI filling the void left by the loss of transcendent purpose.
- Iain McGilchrist on the need for God. Lennox reports a direct conversation with McGilchrist in which McGilchrist said ‘we must make room for God.’ McGilchrist’s left-brain/right-brain analysis converges with Lennox’s diagnosis: left-hemisphere dominance produced materialism; restoration requires recovering what the right hemisphere knows — that the world is not merely a mechanism to be manipulated.
- Secular utopias fail at guilt. The Enlightenment promised that education and reason would make people good. It did not address the power to change. No system of laws or gurus provides the capacity to keep them. The Gospel’s claim — a fundamental flaw, a diagnosis, and a cure — is radical precisely because no alternative offers anything analogous.
The great reversal
Lennox opens with CS Lewis quoting Whitehead: ‘Men became scientific because they expected law in nature, and they expected law in nature because they believed in a lawgiver.’ The 16th- and 17th-century pioneers of science were Christians; the science-versus-religion framing is a 19th-century confection. The grand renversement is the return of serious thinkers — Peterson, Holland, Hirsi Ali — to that earlier consilience.
The case for Christianity is not weakened by intellectual scrutiny but strengthened by it. Oxford’s own motto — Dominus illuminatio mea, the Lord is my light — was chosen by people who thought about God as the precondition of knowledge.
The self-refutation of naturalism
The argument runs: (1) naturalism holds that mind emerged from a mindless, unguided evolutionary process; (2) science requires trusting one’s mind to reason correctly; (3) therefore, under naturalism, the tool used to establish naturalism cannot be trusted. Lennox uses a concrete analogy: no scientist would trust a computer produced by a mindless process to deliver reliable results tomorrow. The naturalist faces the same problem with their own cognition. Shoot yourself in the foot is survivable; shoot yourself in the brain is not.
The argument is closely related to Alvin Plantinga’s evolutionary argument against naturalism (EAAN). See Consciousness and the treatment in Iain McGilchrist on Consciousness, Attention, and the Nature of Reality (TOE).
AI as God-surrogate
Lennox identifies a cultural logic: Christianity was removed, but polytheism rather than atheism took over — each person their own deity. AI amplifies this danger. The claim that machines are or will become conscious runs aground on the hard problem: nobody knows what consciousness is, so nobody can engineer it. The danger is not a genuinely conscious machine but the treatment of AI as God: omniscient, omnipresent, not bound by human weakness.
A secondary danger: treating oneself as God produces misery because self-deification requires perfection, and failure must therefore always be someone else’s fault. Nietzsche saw this: ‘If there were a God, I couldn’t bear not to be he.‘
McGilchrist and the left-brain critique of materialism
Lennox describes a recent conversation with Iain McGilchrist in which McGilchrist articulated a ‘left-brained solution to the demolition of materialism’ — using the rigour of analytical thought to expose its own limits. McGilchrist’s hesitation about doctrine (doctrine = left-brain codification) is understood, but Lennox argues both hemispheres are needed: history’s high points are times of balance. McGilchrist explicitly concluded that ‘we must make room for God’ and ended an Oxford lecture with Dominus illuminatio mea. See Iain McGilchrist on Attention, the Sacred, and Consciousness as Ontological Primitive.
Guilt, forgiveness, and the failure of Utopias
The Enlightenment’s bet was that reason and education would render guilt obsolete. It did not work. The culture now has no tools for dealing with guilt — it is barely acknowledged — yet the demand for forgiveness persists. The palette of self-help gurus supplies rules but not power. Tom Holland’s reading of the Cross is relevant here: the strangeness of a God who enters history to bear guilt on behalf of the guilty is precisely what stands against every Greek or Roman value of strength and self-sufficiency.
Revelation and reason
Lennox counters the false opposition between revelation and reason using the Aunt Matilda cake analogy: all the science in the world cannot explain why she made it without her telling you — yet once she tells you, you use your reason to evaluate her statement. Revelation does not suspend reason; it gives reason something to work on that observation alone cannot supply.
