 According to Russell, it is the philosopher’s job to discover a logically ideal language – a language capable of describing the world in such a way that we will not be misled by the accidental, imprecise surface structure of natural language. As Russell writes, “Ordinary language is totally unsuited for expressing what physics really asserts, since the words of everyday life are not sufficiently abstract. Only mathematics and mathematical logic can say as little as the physicist means to say” (1931, 82). Just as atomic facts (the association of properties and relations with individuals) combine to form molecular facts in the world itself, such a language will allow for the description of such combinations using logical connectives such as “and” and “or.” In addition to the existence of atomic and molecular facts, Russell also held that general facts (facts about “all” of something) are needed to complete our picture of the world. Famously, he vacillated on whether negative facts are also required (1918, 1919).
