 Russell’s philosophical method has at its core the making and testing of hypotheses through the weighing of evidence. Hence Russell’s comment that he wished to emphasize the “scientific method” in philosophy. His method also requires the rigorous analysis of problematic propositions using the machinery of first-order logic. It was Russell’s belief that by using the new logic of his day, philosophers would be able to exhibit the underlying “logical form” of natural-language statements. A statement’s logical form, in turn, would help resolve various problems of reference associated with the ambiguity and vagueness of natural language.
