School of thought (Vienna Circle, Ayer). A claim means its method of verification; the rest is noise. Canonical summary, not a person.

Positions & sources
| Question | Position | Source |
|---|---|---|
| Humans came to exist by: | Evolution by natural processes, no guidance needed | Vienna Circle manifesto (1929) — the scientific world-conception, as above. |
| God exists | The question itself is meaningless — there is no proposition here to evaluate | Ayer, Language, Truth and Logic (1936): the utterance 'God exists' is metaphysical — literally nonsensical, neither true nor false; this profile takes the question itself to be meaningless. |
| Human beings arose entirely through unguided natural processes | Probably true | "The Scientific Conception of the World: The Vienna Circle" (manifesto, 1929) — the school's programmatic alignment with the findings of modern natural science, unguided by anything supernatural. |
| Consciousness is produced entirely by the brain | Probably true | Carnap, "Psychology in Physical Language" (Erkenntnis, 1932) — the physicalist thesis: psychological statements are translatable into the physical language. |
| With the past exactly the same, our choices could have gone otherwise | Probably false | Ayer, "Freedom and Necessity," in Philosophical Essays (1954) — compatibilism: freedom is absence of constraint, not alternative possibilities from an identical past. |
| Some actions are wrong no matter what any person or culture believes | The question itself is meaningless — there is no proposition here to evaluate | Ayer, Language, Truth and Logic (1936), ch. VI: ethical utterances express feeling rather than propositions — 'wrong' is not truth-apt, so there is no proposition here to rate. |
| Long-standing traditions usually contain wisdom we can't see | Probably false | Vienna Circle manifesto (1929) — the scientific conception defines itself against inherited metaphysical tradition. |
| Experts are usually right about questions in their own field | Probably true | Ayer, Language, Truth and Logic (1936) — empirical questions are the province of science; its methods are the paradigm of knowledge. |
| What makes a claim meaningful and truth-evaluable? | It must be empirically verifiable in principle, or analytically true by virtue of its meaning | Ayer, Language, Truth and Logic (1936): a proposition is meaningful if it is either analytic or empirically verifiable in principle — the verification criterion of meaning. |
| An unfamiliar chemical is in a product you use at home. Which would most convince you it is toxic? | A controlled study showing harm in animals at realistic doses | The empiricist answer, after Ayer, Language, Truth and Logic (1936): a factual claim about a chemical is justified by controlled observation and experiment. |
| Consider a statement about the ultimate nature of reality. Its proponents say it expresses a deep truth, but they cannot identify any possible experience that would count for or against it, and it is not true by definition or logic. Is the statement cognitively meaningful? | It is cognitively meaningful only if it is analytically true or has empirical implications that make it verifiable in principle; otherwise, it does not express a factual proposition | Ayer, Language, Truth and Logic (1936): a statement with no empirical implications and no analytic truth is literally nonsensical — the stipulated case is the textbook example. |
