Laws and Dispositions

Abstract

Laws are supposed to tell us how physical systems actually behave. The analysis of an important part of physical practice—abstraction—shows, however, that laws describe the behavior of physical systems under very special circumstances, namely when they are isolated. Nevertheless, laws are applied in cases of non-isolation as well. This practice requires an explanation. It is argued that one has to assume that physical systems have dispositions. I take these to be innocuous from an empiricist's standpoint because they can—at least in principle—be measured. Laws can be applied whenever such a disposition is present, they describe how the physical system would behave if the disposition were manifest.
