Laws of God or Laws of Nature?
The appeal to laws of nature as an explanatory principle is often regarded as fundamental to naturalism. Yet when the idea that there were immutable, mathematical laws of nature first rose to prominence in the seventeenth century it was deeply connected to a theological understanding of natural order. Descartes thus imagined laws of nature to be divine commands, and attributed their immutability to the immutability of their divine source. For Descartes, Boyle, and Newton, the invariable uniformity of nature was understood as a consequence not of God’s withdrawal from the world, but of his direct and incessant engagement with it. It followed that the world was to be investigated empirically, because this was the only way in which the otherwise inscrutable will of God could be discerned. Over the course of the following centuries, however, laws came to be reimagined as simply observational generalizations, or brute features of the natural world.
