I want to know the answer to the following question:
When did Bertrand Russell die?
All the background I'm provided with is that "They saw in the logical symbolism elaborated by Frege (1848–1925) and Bertrand Russell (1872–1970) a powerful instrument that could rationally reconstruct all scientific discourse into an ideal, logically perfect, language that would be free of the ambiguities and deformations of natural language.". Is that enough to answer the question?
