Natural and social sciences seem very often to hedge their laws by ceteris paribus clauses - a practice which is philosophically very hard to understand because such clauses seem to render the laws trivial and unfalsifiable. This volume collects the most prominent philosophers of science in the field and presents a lively, controversial, but well-integrated, highly original discussion of the issue. It will be the reference book in the coming years concerning ceteris paribus laws.
