 It is with these kinds of examples in mind that Russell suggests we adopt what he calls “the supreme maxim in scientific philosophizing,” namely the principle that “Whenever possible, logical constructions,” or as he also sometimes puts it, “logical fictions,” are “to be substituted for inferred entities” (1914c, 155; cf. 1914a, 107, and 1924, 326). Anything that resists construction in this sense may be said to be an ontological atom. Such objects are atomic, both in the sense that they fail to be composed of individual, substantial parts, and in the sense that they exist independently of one another. Their corresponding propositions are also atomic, both in the sense that they contain no other propositions as parts, and in the sense that the members of any pair of true atomic propositions will be logically independent of one another. Russell believes that formal logic, if carefully developed, will mirror precisely, not only the various relations between all such propositions, but their various internal structures as well.
