John Lennox on Has Science Buried God, Levels of Explanation, and Evidence-Based Faith
A lecture given by Oxford mathematician John Lennox at Southern Methodist University. Lennox dismantles the assumption that science and Christian faith are in competition: they occupy different explanatory levels, answer different kinds of question, and have historically reinforced each other. The lecture is a systematic rebuttal of the four main atheist arguments — the displacement argument, the self-sufficiency of science, the God-of-the-gaps charge, and the Freudian wish-fulfilment claim — using analogy throughout.
Key ideas
- Science explains how; theology explains why. The boiling kettle can be described by thermodynamics (mechanism) and by ‘I want a cup of tea’ (purpose and intention). Both answers are correct; neither replaces the other. Science cannot answer why — why there is something rather than nothing, why the universe is rationally comprehensible, why moral intuition persists. See Levels of Explanation.
- Scientism is self-refuting. ‘Science is the only way to truth’ is not a scientific statement and cannot be established by science. It is a philosophical position — a faith position — that fails its own test.
- Newton and Hawking used the same law of gravity, reached opposite conclusions. Their divergence was not scientific but philosophical: different worldviews applied to the same data. Science does not come with interpretations pre-attached.
- Faith means evidence-based trust, not credulity. The Greek pistis and Latin fides both mean fidelity, trust. Einstein’s faith that the universe is rationally intelligible was the engine of his science. All science operates on faith in the coherence of the universe.
- Freud’s wish-fulfilment argument reverses. Psychiatrist Manfred Lutz: the wish that there is no God to whom you are accountable is at least as plausible a psychological driver as the wish for a cosmic father. The argument from psychology proves nothing about whether God exists.
Science and religion as explanatory levels
The central move of the lecture is structural. Lennox argues that the opposition of ‘science versus God’ rests on a category error: treating God as if he were a competing scientific explanation — a mechanism that might be displaced by a better mechanism. The boiling kettle analogy makes this vivid. Henry Ford as inventor of the internal combustion engine is not displaced by an engineer explaining how combustion works; the two explanations are at different levels. God as creator and sustainer of the universe is not at the same level as the law of gravity; God is the reason there are physical laws at all.
This is Wittgenstein’s insight from the Tractatus and Philosophical Investigations: the laws of nature are not explanations of phenomena; they are descriptions. Asking ‘what explains the law of gravity?’ takes you outside physics. Naturalism has nothing to say here; theism has a natural answer.
Newton versus Hawking
Newton discovered the law of gravity and used it to argue for God; Hawking used the same law and argued against the need for God. The science is identical. The divergence is in worldview — the philosophical framework brought to the science. Lennox’s point is that this distinction is almost never made in popular discourse, where science is treated as if it carries its own interpretation. It does not. Philosophers of science have known this since at least the Vienna Circle; the point is standard in philosophy of science but absent from the science-versus-religion media debate.
The God-of-the-gaps distinction
Lennox carefully distinguishes the God of the gaps (a shrinking God who fills unexplained phenomena, justifiably threatened by scientific advance) from the God of classical theism (the primary cause who sustains the existence and rationality of the universe, not threatened by any advance in understanding secondary causes). Newton did not use God as a placeholder for ignorance; he saw law-governed regularity as evidence of a lawgiver. These are opposite moves.
The new atheist argument from the retreat of God-of-the-gaps explanations applies only to the first kind of God and has no force against the second. Most theologians in the Christian tradition have always distinguished primary and secondary causation; the new atheists are arguing against a straw man.
Faith and evidence
The Twain caricature — ‘believing what you know ain’t so’ — is not the biblical or theological concept of faith. Pistis (Greek) and fides (Latin, source of ‘fidelity’) are primarily about trust grounded in evidence. Lennox’s examples: sitting in an aeroplane (trust based on engineering track record), Einstein’s faith in rational intelligibility (the productive assumption on which all science rests). Biblical faith is tested, reasoned, evidence-responsive. The claim that faith is intrinsically irrational misreads both the word’s history and its use in scripture.
The Aunt Matilda analogy
Appears in both the AI lecture and this SMU lecture. Lennox uses it here for revelation: science is comprehensive within its domain but cannot reach the why of the universe without being told. Aunt Matilda’s reason for baking the cake — ‘for cousin Jane’ — cannot be recovered by any amount of chemical analysis. When she tells you, you use your reason to evaluate the claim (Is she credible? Consistent?). Revelation and reason are complementary, not opposed. This is also the argument for the necessity of Scripture: not to replace science but to answer the questions science is not designed to address.
