Science works. The germ theory of disease, the structure of DNA, the age of the universe, the mechanism of evolution, the behaviour of subatomic particles. These are genuine achievements of human inquiry, established through a rigorous method of hypothesis, experimentation, and revision in response to evidence. Anyone who dismisses the authority of science on questions within its domain is making an error.
The question is whether science is all there is, whether every genuine question is in principle a scientific question, and whether questions that science cannot answer are therefore not genuine questions.
That position (scientism) is held explicitly by some and implicitly by many more. It is also, on examination, incoherent.
The self-refutation of scientism
Scientism is the claim that only empirically testable claims are meaningful or capable of being known. The claim itself is not empirically testable. You cannot design an experiment to test whether “only empirically testable claims are meaningful.” The claim belongs to philosophy rather than to science. It is a metaphysical position about the nature and limits of knowledge, exactly the kind of position it declares to be meaningless.
This is a structural objection rather than a trivial one. Scientism undermines itself before it gets started. It is not a position that can be defended using the methods it endorses.
Questions science does not answer
Even setting aside the self-refutation, there is an obvious practical problem: many of the most important questions human beings face are not scientific questions. Why does the universe exist? What makes an action genuinely right or wrong? Is the external world real or a representation in a mind? What is it for a mathematical proof to be valid? Is there meaning in conscious experience beyond what physical processes produce?
These are not questions science has failed to answer yet. They are questions of a different kind (philosophical, logical, metaphysical) that the empirical method was not designed to address. Science investigates the physical world by gathering data about it. Questions about the ground of the physical world, the basis of logic, the nature of consciousness, and the reality of moral facts are prior to the scientific enterprise rather than within it.
What this means for the God question
The claim “science has disproved God” is therefore a category error. Science can provide evidence relevant to the God question. The Big Bang points toward a beginning, fine-tuning raises questions about design, the existence of consciousness raises questions about the reducibility of mind to matter. Science contributes to the inquiry. It cannot resolve it, because the God question is at its core a metaphysical question: is there a transcendent ground of reality? That question is asked at a level prior to empirical investigation, and it must be answered (or left unanswered) through philosophical rather than experimental means.
The person who says “I only believe what science tells me” is not being scientific. They are making a philosophical commitment that goes beyond what science itself can establish. And if they are willing to make philosophical commitments, then the philosophical arguments for God’s existence deserve the same hearing as any other serious philosophical inquiry.
Does science need God to function?
There is an argument that goes further than compatibility. The scientist assumes that the same cause will always produce the same effect, that nature operates according to immutable patterns. Why should this be true? From pure empirical observation, you can only say that a cause has produced a certain effect so far. You cannot derive from observation alone that it will always do so. David Hume demonstrated this, and no empiricist has answered him.
The Islamic tradition has an answer. Al-Ghazālī made the argument in the eleventh century: the orderliness of nature (the very thing that makes science possible) is not self-grounding. It rests on the constancy of God’s creative will. The laws of nature are God’s sunan (immutable patterns), implanted in creation and sustained by His continuous action. They are immutable because God does not change His way, rather than because matter has some inherent compulsion to obey them. The Quran states this directly:
The Muslim has a rational basis for trusting that nature is lawful, a basis the materialist does not have. The materialist’s trust that tomorrow’s experiment will behave like today’s is, as Santayana noted, a piece of “animal faith.” The Muslim’s trust is grounded: God’s patterns are constant because God is constant. Science works because creation is not chaos, and creation is not chaos because its Author is One.
The Prophet on the pursuit of knowledge
The Prophet ﷺ established the seeking of knowledge as a religious duty:
The hadith establishes that the pursuit of knowledge is something other than a peripheral concern of the faith. It is a binding religious duty. The classical Islamic tradition has always read the obligation as covering both the religious sciences and what the scholars called al-ʿulūm al-ʿaqliyyah (the rational sciences): mathematics, medicine, astronomy, natural philosophy, logic. The civilisations that produced the House of Wisdom in Baghdad, the medical works of Ibn Sīnā, the astronomical work of al-Bīrūnī, and the optical treatises of Ibn al-Haytham were operating on this hadith’s instruction. Science is one of the forms that Islamic religious obligation takes, rather than a conflict with it.
Faith and science: the actual relationship
The great theistic traditions have no stake in the failure of science. The tradition of serious rational inquiry, which across many centuries and civilisations has been inseparable from religious scholarship, is not a tradition threatened by honest empirical investigation. The conflict is between faith and scientism (the philosophical position that science has replaced all other modes of knowing), rather than between faith and science. That position is refuted by reason before religion gets a word in. Science is a method. What it cannot do is validate the philosophical claim that it is the only valid method, since that claim exceeds what any experiment can establish.
God as the source of normativeness
There is a further step that most Western discussions of God miss entirely. In the Islamic philosophical tradition, God is the core of normativeness, rather than merely the first cause or even a personal mind. His existence is a moral event rather than just a metaphysical fact. Every attribute of God (His knowledge, His justice, His mercy) simultaneously functions as a command. To know that God is just is to know that justice is required of you. To know that God is the source of being is to know that your being has a purpose you did not author.
The position distinguishes the Islamic conception from the deist’s distant clockmaker. The deist’s God creates and withdraws. The God of tawḥīd creates and remains the permanent ground of all value, all obligation, all meaning. His existence does not leave the universe as it was. His existence restructures everything. The laws of nature are His patterns. The moral law is His command. Human consciousness, the one part of creation capable of freely choosing to align with those patterns, becomes the bearer of a cosmic vocation.
Proving God’s existence is therefore the beginning of the inquiry rather than the end. Once the reality of a conscious, good, purposive Creator is established, the question is no longer whether you believe; the question is what you owe.
Much of the force of the objection depends on treating one element of Islam in isolation. Once the larger picture is restored (God, accountability, mercy, justice, and the purpose of revelation) the argument usually looks less decisive than it first appeared.
The unity of truth is the foundational principle. If God authored both revelation and the natural world, then the findings of science and the claims of revelation cannot ultimately contradict. Where they appear to, the contradiction is in human understanding, and the Islamic tradition demands that both be re-examined rather than either being dismissed. This is the deepest possible commitment to truth from every source, rather than an anti-science stance.
