I happened to come across a short article by Henri Poincaré regarding the evolution of laws. You surely haven’t read it as it is out of print, something only bibliophiles can find. Émile Boutroux, who was a philosopher, raised the question whether it was unthinkable that laws themselves evolve. Poincaré, who was a mathematician, got all up in arms at the idea of such evolution, since what a scientist is seeking is precisely a law insofar as it does not evolve. It is exceedingly rare for a philosopher to be more intelligent than a mathematician, but here a philosopher just so happened to raise an important question. Why, in fact, wouldn’t laws evolve when we conceive of the world as having evolved? Poincaré inflexibly maintains that the defining characteristic of a law is that, when it is Sunday, we can know not only what will happen on Monday and Tuesday, but in addition what happened on Saturday and Friday. But it is not at all clear to me why the real would not allow for a law that changes.
