Ceteris Paribus clauses in reasoning are used to allow for defeaters of norms, rules or laws, such as in von Wright’s example “I prefer my raincoat over my umbrella, everything else being equal”. I offer an analysis in which sets of formulas S, embedded in modal operators, provide necessary and sufficient conditions for things to be equal in ceteris paribus clauses. I’ll talk about how ceteris paribus preferences can be formalised and discuss questions that arise with the formalisation, and propose some solutions.
