Abstract

Deals with the initial phase of the reaction, by Moore and Russell, against Idealism. In opposition to that view, they developed an extreme form of realism, which the author calls ‘Platonic Atomism’. The idea of a ‘proposition’ is fundamental for this view. Truth is undefinable, and facts are merely those propositions that happen to be true. Among the most important works here are Moore's ‘Nature of Judgement’ and Russell's 1901 book on Leibniz; the same metaphysical view underlies Moore's Principia Ethica.
