“The traditional disputes of philosophers are, for the most part, as unwarranted as they are unfruitful.”
Source: Language, Truth, and Logic (1936), Ch. 1, first lines.
Context: The traditional disputes of philosophers are, for the most part, as unwarranted as they are unfruitful. The surest way to end them is to establish beyond question what should be the purpose and method of a philosophical enquiry. And this is by no means so difficult a task as the history of philosophy would lead one to suppose. For if there are any questions which science leaves it to philosophy to answer, a straightforward process of elimination must lead to their discovery.

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.

...replacer, autant que possible, les œuvres dans les conditions concrètes où elles ont été écrites, conditions spirituelles d’une part, c’est-à-dire tradition philosophique, rhétorique ou poétique, conditions matérielles d’autre part, c’est-à-dire milieu scolaire et social, contraintes venues du support matériel de l’écriture, circonstances historiques. Toute œuvre doit être replacée dans la praxis dont elle émane.
