Abstract
Deals with the evolution of Russell's metaphysical and epistemological views, from roughly 1906 to 1913. In metaphysics, he gives up on the primacy of propositions and the undefinability of truth; facts become fundamental, and truth defined. Epistemology becomes a far more central concern of Russell's than before and is dominated by the idea of acquaintance, a presuppositionless relation between the mind and entities outside the mind. In both fields, Russell develops a constructivist method, greatly influenced by logic, which was to have a far‐reaching influence on later analytic philosophy.
