Abstract

I invoke the conceptual machinery of contemporary possible-world semantics to provide an account of the metaphysical status of “bridge laws” in intertheoretic reductions. I argue that although bridge laws are not definitions, and although they do not necessarily reflect attribute-identities, they are supervenient. I.e., they are true in all possible worlds in which the reducing theory is true.
