    Keynes's framework permits no learning from experience and thus cannot adequately justify analogical reasoning when negative analogy exists

    Reasons For

    2 perspectives
    Reason for 1 of 2
    ?
    • 1.Keynes treats probability as a purely logical relation between propositions, fixed by their content alone, independent of empirical updating.
      ?

      Think about whether this reason is strong or weak

    • 2.Carnap's later inductive logic explicitly showed that purely logical probability systems require a continuum of lambda values to handle negative analogy, which Keynes's single framework cannot accommodate.
      ?

      Think about whether this reason is strong or weak

    • 3.A probability measure that cannot shift its assignments in response to accumulated negative instances fails the basic Bayesian coherence condition that posteriors must differ from priors given relevant evidence.

      Think about whether this reason is strong or weak

    Reason for 2 of 2
    ?
    • 1.Mill's methods of induction require that negative instances actively disconfirm analogical hypotheses, a dynamic process Keynes's static logical relations structurally prohibit.
      ?

      Think about whether this reason is strong or weak

    • 2.When negative analogy exists, Keynes's framework assigns the same probability to the analogical conclusion as before those disanalogous instances were identified, rendering the negative analogy epistemically inert.
      ?

      Think about whether this reason is strong or weak

    • 2.If there is a non-trivial negative analogy, the probability of the conclusion remains unchanged under Keynes's framework

    Recasting analogy as a deductive argument may help to bring out background assumptions, but it makes little headway with the problem of justification. That problem re-appears as the need to state and establish the plausibility of a determination rule, and that is at least as difficult as justifying the original analogical argument. 2 Inductive justification Some philosophers have attempted to portray, and justify, analogical reasoning in terms of some well-understood inductive argument pattern.
