natural law?

There is a division between the thing itself and the laws which govern it.  Unless, of course, one holds that it is self-governed or autonomous (Gk: auto, self; Gk: nomos, law), which seems just as assumptive as claiming it is ruled by an ‘other’.

If nature is governed by laws, then those laws themselves are not themselves the thing they are governing, and are therefore not ‘within’ (Lat: intra) nature.  This could only mean that they are other than, outside of or ‘above’ (Lat: supra) nature.
