The Development of Russell's Diagrams for Judgment

  • Rosalind Carey CUNY Lehman College


In his 1918 lectures, The Philosophy of Logical Atomism, Russell discusses the impossibility of drawing a diagram or "map-in-space" of the form of belief (judgment). In this paper, I argue that an examination of diagrams appended to Russell's Theory of Knowledge shows him already anticipating this symbolizing difficulty in 1913 and—in the midst of attempting to adopt Wittgenstein's doctrine of propositional bipolarity—jettisoning attempts to diagram the form of belief.
