The Problem of Harmonizing Laws.

More laws obtain in the world, it appears, than just those of microphysics – e.g. laws of genetics, perceptual psychology, economics. This paper assumes there indeed are laws in the special sciences, and not just scrambled versions of microphysical laws. Yet the objects which obey them are composed wholly of microparticles. How can the microparticles in such an object lawfully do more than what is required of them by the laws of microphysics? Are there additional laws for microparticles – which seems to violate closure of microphysics – or is the ``more'' a coincidental outcome of microphysics itself? This paper argues that the appearance of violation is illusory, and the worry about coincidence misleading. We cannot expect to understand the special sciences at the level of the microparticles.
