The authority of science in contemporary culture is enormous, and largely deserved. The scientific method (formulating testable hypotheses, gathering empirical evidence, revising theories in response to data) has produced the most reliable body of knowledge about the physical world that human beings have ever assembled. From germ theory to genetics, from quantum mechanics to cosmology, science has transformed what we understand and what we can do.
Science’s authority has a scope. It applies to empirically testable claims about the physical world. It does not apply to all claims, including some of the most important ones human beings face.
What scientism is
Scientism is the view that science is the only reliable method of acquiring knowledge, that any question science cannot in principle answer is not a genuine question, or has no genuine answer. Scientism is distinct from science itself, which is a method for investigating the physical world. Scientism is a philosophical claim about the nature and limits of knowledge, and it is a claim that cannot itself be established scientifically.
The self-refutation is decisive. The claim “only empirically testable claims are meaningful” is itself a non-empirical philosophical proposition about epistemology. The claim cannot be established by the very method it privileges. Scientism is a philosophical position that fails by its own stated criteria.
Questions science does not answer
Science describes how things work. It does not explain why there is anything to work at all. The existence of the universe (that there is something rather than nothing) is not a scientific question in any straightforward sense. Science begins with the universe already in existence and investigates its structure and regularities. The question of why the universe exists, rather than not, lies outside the domain where the scientific method has purchase.
Science describes the structure of consciousness (which neurons fire, which chemicals are released, which brain regions activate). It does not explain why any of this physical activity is accompanied by subjective experience. Why is there something it is like to see red, to feel pain, to experience joy? This question (the hard problem of consciousness) is something other than a gap that further neuroscience will close. It is a philosophical problem about the relationship between physical processes and inner experience that sits outside the reach of empirical measurement.
Science describes how moral reasoning works (the evolutionary pressures that may have shaped moral intuitions, the neural correlates of moral judgements). It does not establish what is actually good or right. The fact that some societies evolved norms of cooperation says nothing about whether those norms are objectively binding. The move from “this is how morality evolved” to “this is what morality is” is a philosophical step that science cannot take.
The limits are internal, not external
These limits are not imposed on science from outside by people who want to protect religion. They are limits that emerge from understanding what scientific investigation actually does. Scientists themselves (including some of the most prominent figures in physics, biology, and philosophy of science) have acknowledged that their methods have a defined domain, and that questions about meaning, consciousness, ethics, and existence sit outside it.
This matters for the God question because a common move in popular atheism is to say that science has shown there is no room for God. Science does not have tools for examining the God hypothesis. It can investigate whether particular miraculous claims are consistent with natural regularities. It cannot investigate whether a non-physical cause of the physical world exists. That question lies in the domain of metaphysics and philosophy of religion, rather than in the domain of empirical investigation.
The Quranic view of knowledge
The Quran takes a position on the limits of human knowledge that is consistent with the philosophical analysis above:
The verse identifies a structural feature of the human epistemic condition. Human knowledge is real but finite. The acknowledgement is the precondition for the proper use of the faculties God has given. Scientism, by contrast, fails to acknowledge the structural limits of the method it privileges. The Quran’s framing is the framing the philosophy of science itself has converged on: knowledge is genuine but partial, methods have proper domains, and the recognition of those limits is the mark of intellectual maturity rather than its absence.
The Quran also celebrates rational inquiry within its proper scope. The text repeatedly directs the reader to observe, reflect, and reason about the natural world:
The verse uses the term ulū al-albāb (people of understanding, those whose intellects function with depth and discernment). The Quran is not opposed to scientific inquiry. The Quran encourages it, and identifies the empirical investigation of the natural world as one of the principal routes by which the human creature comes to recognise the signs of God. What the Quran rules out is the move from empirical investigation to scientism: the claim that the empirical method exhausts the domain of legitimate knowledge.
What this does not establish
Noting the limits of science does not establish that God exists, that religion is true, or that any particular metaphysical claim is well-grounded. It establishes that the most influential cultural argument against theism (that science has replaced God, that the God hypothesis is superfluous in a scientific age) rests on a confusion about what science is and what it does.
The God question must be answered in the domain where it belongs: philosophy of religion, metaphysics, examination of the arguments.
Notice what the restriction to scientific method actually requires. Science itself depends on logical inference, on the assumption that valid arguments track truth, that evidence is relevant to conclusions, that the universe is rationally structured in a way that makes investigation possible. These assumptions are not established by scientific method. They are presupposed by it. If you ask why rational inference is reliable, why the universe is intelligible, why mathematical structures describe physical reality, science cannot answer those questions from within itself. They are prior to science. Answering them requires philosophy and, ultimately, an account of what kind of universe we are in. A universe whose rational structure is self-explaining is not obviously more credible than one whose rational structure is grounded in a rational Creator. The question is open, and it is not settled by appealing to the method whose foundations are themselves in question.
In that domain, the case for a Creator is not obviously weaker than the case against one. It deserves to be assessed there rather than dismissed by pointing to telescopes and laboratories that were never designed to look for what is being asked about.
The Islamic framework on the unity of truth
The Islamic principle that bears most directly on the limits-of-science question is the unity of truth: if God is one and the source of all reality, then science (which investigates the patterns of God’s creation) and revelation (which addresses the questions science cannot reach) are complementary rather than rival sources of knowledge. The reduction of all legitimate knowledge to one of them is a violation of the unity. The classical Islamic intellectual tradition produced six centuries of scientific work alongside its theological and philosophical work because its operating principle was that truth is one, that empirical and metaphysical questions both have answers, and that the rigorous pursuit of either kind of question is part of the human creature’s vocation. The contemporary reader who has been told that science has replaced religion is being asked to accept a fragmentation of knowledge that the Islamic tradition rejected from its foundations.
