Title: Difference-making conditionals and the Relevant Ramsey Test 
Abstract: 
This talk explores conditionals expressing that the antecedent makes a difference for the consequent. A 'relevantised' version of the Ramsey Test for conditionals is employed in the context of the classical theory of belief revision. The idea of this test is that the antecedent is relevant to the consequent in the following sense: a conditional is accepted just in case (i) the consequent is accepted if the belief state is revised by the antecedent and (ii) the consequent fails to be accepted if the belief state is revised by the antecedent's negation. The connective thus defined violates almost all of the traditional principles of conditional logic, but it obeys an interesting logic of its own. If there is time, I will also compare difference-making conditionals with 'evidential conditionals' or 'contraposing conditionals' as studied recently by Crupi & Iacona and Raidl
