Two black riddles make a white answer.
In fairyland we avoid the word "law"; but in the land of science they are singularly fond of it.

Thus they will call some interesting conjecture about how forgotten folks pronounced the alphabet, Grimm's Law.

But Grimm's Law is far less intellectual than Grimm's Fairy Tales.
The tales are, at any rate, certainly tales; while the law is not a law.
A law implies that we know the nature of the generalisation and enactment; not merely that we have noticed some of the effects.
