Editing Naturalism in a Fine-Tuning Feature
A science magazine has a 1,600-word freelance feature on cosmologist Dr. Lena Alvarez, who has published on fine-tuning and argues that the multiverse is a metaphysical rather than a physical hypothesis. The draft contains this passage: 'Like every scientist, Alvarez is a naturalist - which is why she rejects any design hypothesis. Her colleague Dr. Okafor, who is a theist, is therefore working outside the bounds of science. The two positions are simply non-overlapping: science answers how, religion answers why.' The fact-checker has flagged all three sentences but cannot say precisely what is wrong. The editor has 48 hours before publication and three options: cut the passage, run it as the writer's opinion, or correct it. The magazine's style guide requires that contested philosophical claims be attributed to a named source rather than asserted in the magazine's voice, and that positions be described using the terms their holders use.
1. Distinguish methodological naturalism, metaphysical naturalism, and scientism, then identify which error each of the three sentences commits.

Methodological naturalism is a rule of method: in explaining natural phenomena, inquiry restricts itself to natural causes, not because nothing else exists but because the method is what has produced reliable, testable results. It is a procedural commitment compatible with many metaphysical positions.
Metaphysical (or ontological) naturalism is a claim about what exists: nature is all there is, and there is no God, soul, or non-natural entity. It is a substantive philosophical position, not a methodological one, and it is not entailed by the success of scientific method.
Scientism is the further claim that science is the only or the supreme source of knowledge, so that claims outside its scope are not merely untestable but meaningless or irrational.
Sentence one ('Like every scientist, Alvarez is a naturalist - which is why she rejects any design hypothesis') commits two errors. The universal quantifier is false as an empirical matter: many working scientists are theists, and the magazine's own style rule would forbid asserting this in its voice. More importantly, it slides from method to motive. Rejecting a design hypothesis is usually a judgment about testability, explanatory scope, and the track record of naturalistic explanation - not a metaphysical commitment doing the work.
Sentence two conflates theism with science-incompetence. A theist can practise methodological naturalism perfectly well; Okafor's theism bears on his metaphysics, not on his ability to run a survey or fit a spectrum. Calling him 'outside the bounds of science' is scientism smuggled in as description.
Sentence three is the non-overlapping magisteria claim, which is a contested thesis stated as though it were a truism.
2. Rewrite the passage so that it is accurate and complies with the style guide.

Sample rewrite: 'Alvarez describes herself as a methodological naturalist: she holds that cosmology should appeal only to natural causes, and she argues that the multiverse, because it may be untestable, is a metaphysical rather than a physical hypothesis. Critics reply that this cuts against her own position as much as against design arguments. Her colleague Dr. Okafor is a theist who works within the same methodological constraints; he argues that theism and scientific practice answer different questions, though he does not claim the two never intersect. Whether the design hypothesis counts as science is contested among philosophers of science, and the disagreement is not settled by the methods of cosmology itself.'
The rewrite does four things. It replaces the universal claim about scientists with an attributed claim about one scientist. It separates what Alvarez holds (method) from the inference the writer wanted to draw (motive). It describes Okafor's position using his own terms, so that theism is not equated with scientific incompetence. It marks the demarcation question as contested and attributes it.
What the rewrite deliberately does not do is adjudicate. The magazine's job is to report that Alvarez and Okafor disagree about whether the multiverse is physics or metaphysics, and to represent each position at its strongest, not to settle a live philosophical dispute in a feature. If the editor wants a verdict, it must come as a signed opinion piece with a named author, clearly separated from reporting.
3. Evaluate the claim 'science answers how, religion answers why.' Under what conditions does it hold, and when does it fail?

The formula descends from the non-overlapping magisteria proposal and is attractive because it promises peace. It holds only under narrow conditions: when 'why' is restricted to questions of purpose, meaning, and value, and when the religious claims in question make no empirically assessable assertions.
It fails on at least three fronts. First, the how/why distinction is not clean. 'Why did the dinosaurs go extinct?' is a causal question answered by science; 'why is there something rather than nothing?' is a metaphysical question on which science has partial and contested things to say. The particle 'why' does not track the boundary.
Second, religions routinely make claims that are in principle empirical or historical - about events in the world, about the age of the earth, about the efficacy of petitionary prayer, about the fate of a body after death. Once a claim is empirical, silence is not neutrality; it is a missed prediction, and the formula cannot protect it.
Third, the formula is asymmetric in practice. It is usually deployed to keep religion out of scientific disputes while leaving science free to imply that religious questions are merely decorative. That asymmetry is why critics on both sides reject it - some theists because it trivializes their truth claims, some naturalists because it grants immunity to claims they think are false.
A more defensible formulation abandons the geography metaphor: science and religion make overlapping and non-overlapping claims, case by case, and the overlaps have to be argued rather than zoned away. For the feature, that means the sentence should never appear in the magazine's voice.
