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 assume s there indeed are laws int he special sciences, and not just scrambled ver sions of microphysical laws. Yet the objects which obey them are composed w holly of microparticles. How can the microparticles in such an object lawfu lly 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 itse lf? This paper argues that the appearance of violation is illusory, and the worry about coincidence misleading. We cannot expect to understand the spe cial sciences at the level of the microparticles.
