An Enquiry Concerning Human Understanding (1748)
Context: THERE is no method of reasoning more common, and yet none more blameable, than, in philosophical disputes, to endeavour the refutation of any hypothesis, by a pretence of its dangerous consequences to religion and morality. When any opinion leads to absurdities, it is certainly false; but it is not certain that an opinion is false, because it is of dangerous consequence. Such topics, therefore, ought entirely to be forborne; as serving nothing to the discovery of truth, but only to make the person of an antagonist odious.

(...) De nouvelles connaissances conduisent à reconnaître dans la théorie de l'évolution plus qu'une hypothèse. Il est en effet remarquable que cette théorie se soit progressivement imposée à l'esprit des chercheurs, à la suite d'une série de découvertes faites dans diverses disciplines du savoir. La convergence, nullement recherchée ou provoquée, des résultats de travaux menés indépendamment les uns des autres, constitue par elle même un argument significatif en faveur de cette théorie.
early news reports mistranslated the French phrase plus qu'une hypothèse as "more than one hypothesis". http://www.cartage.org.lb/en/themes/sciences/LifeScience/PhysicalAnthropology/EvolutionFact/Evolution/Evolution.htm
