[filed under theme 26. Natural Theory / D. Laws of Nature / 7. Strictness of Laws ]

The laws of nature are not simple descriptions of what can be seen to happen. They are descriptions of abstractions and idealisations from a somewhat messy reality.

Gist of Idea

Laws describe abstract idealisations, not the actual mess of nature

A Reaction

This view seems to have increasingly gripped modern philosophers, so that the old view of God decreeing a few simple equations to run the world has faded away.

Laws describe abstract idealisations, not the actual mess of nature [Harré]
We take it that only necessary happenings could be laws [Harré]
Must laws of nature be universal, or could they be local? [Harré]
Being lawlike seems to resist formal analysis, because there are always counter-examples [Harré/Madden]
If there are no finks or antidotes at the fundamental level, the laws can't be ceteris paribus [Burge, by Corry]
Strict laws make causation logically necessary [Maslin]
Strict laws allow no exceptions and are part of a closed system [Maslin]
A 'ceteris paribus' clause implies that a conditional only has dispositional force [Mumford/Anjum]
Hume's Dictum says no connections are necessary - so mass and spacetime warping could separate [Friend/Kimpton-Nye]
