ABSTRACT
There were two main episodes in Russell’s thought about probability and inductive inference. The first occurred around 1930 when he published some short discussions: chapter XXV of his book Philosophy (1927), a popular article ‘Heads or Tails’ in the Atlantic Monthly (1930), a review of Ramsey’s book in Mind (1931), and a shorter review of that same book in the journal Philosophy (1932). The outcome of this first brush was a survey of problems, with attention mainly to Keynes and von Mises, and a passing glance at Ramsey’s subjectivist alternative.
