 ‘A New Species of Logic’

Show Summary Details


This is the central chapter of the book. It contains an extended argument to show that in formal probability theory we have an authentic logic of uncertain inference, of the same species as deductive logic. A soundness and completeness theorem is given for this logic, akin to the soundness and completeness theorems of deductive logic. The logical view of probability was propounded by Leibniz in the seventeenth century, and revived in the twentieth century by Keynes, Carnap, and Ramsey. It is Ramsey's view, that the rules of probability are consistency constraints, that is upheld.
