John Lennox on Science, God, and the Rationality of Belief

OCCA Oxford — The Veritas Forum | ~2019

A public lecture in which Oxford mathematician John Lennox argues that the conflict between science and God is a category error: science and theology occupy different explanatory levels, and the real contest is between two worldviews — atheism and Christian theism — neither of which is delivered by the science itself. The lecture adds a detailed treatment of miracles and theodicy to Lennox’s standard case.

Key ideas

  1. Science rests on faith, not against it. Newton expected law in nature because he expected a lawgiver — and that expectation drove the scientific revolution. Einstein could not imagine a scientist without faith in rational intelligibility. Framing the debate as ‘science versus faith’ already hands the ground to the atheist; both sides require faith, and the real question is which grounds rational inquiry more securely: faith in a rational cosmos produced by Mind, or faith in reason produced by a mindless, unguided process.

  2. Newton and Hawking, same physics, opposite metaphysics. Newton used the law of gravity to argue for God; Hawking used the same law to deny it. The science is identical. Their divergence is philosophical — different worldviews applied to identical data. Science does not interpret itself; interpretation requires a framework that stands outside the science. See Scientism.

  3. Miracles don’t break the laws of nature — they reveal that the universe isn’t a closed system. Hume assumed the universe is causally closed; Lennox denies it. The hotel-room analogy: $200 in a drawer overnight becoming $50 does not refute arithmetic — it proves someone reached in. The constant law is what reveals the intrusion. Needing the laws to recognise a miracle means the laws and the miracle are not in competition; recognising the resurrection required knowing the norm.

  4. A mindless brain cannot ground rational trust. If the brain evolved without design from matter in motion, its outputs — including every scientific theory — have no epistemic warrant. CS Lewis made this point in the 1940s; Alvin Plantinga formalised it as the evolutionary argument against naturalism; Thomas Nagel, an atheist philosopher, concedes materialism faces a serious problem here. Rational thought existing at all is evidence for a rational ground of the universe.

  5. Theodicy reframed: not why, but who. The standard formulation — if God is good, powerful, and omniscient, why is there suffering? — has never resolved. Lennox reformulates: given that the world contains both beauty and bombs, is there any evidence of a God you could trust with it? The cross — God entering human suffering — and the resurrection — guaranteeing final justice — constitute the Christian answer. Not a philosophical explanation, but a window.
