The Ramsey Test as an inference rule

Crocco, Gabriella and Herzig, Andreas


The so-called Ramsey test has been used as a way of giving meaning to conditionals by basing them on an operation of belief change. Contrarily to the usual AGM account we suppose that belief change corresponds to an operator in the object language. This permits to state the Ramsey test in terms of two inference rules. We investigate the minimal logic of updates and conditionals that supports these two inference rules. We show that such a logic can be based on the basic semi-normal logic of conditionals Ck as defined by Chellas.
