Abstract

The Ramsey test for indicative conditionals suggests that they are to be understood in terms of subjective probability. This concept is explained, and elements of probability logic expounded. Indicative conditionals are mostly zero intolerant, meaning that such a conditional is useless to someone who is really sure that its antecedent is false. The Equation is introduced: i.e. the thesis that your probability for ‘If A, C’ (indicative) is your conditional probability for C given A.
