Full Idea
There is indeed natural uniformity in the negative charge of electrons, but the reason for this is that it is an essential property of being an electron that something be negatively charged. It would not be an electron otherwise.
Gist of Idea
The only full uniformities in nature occur from the essences of fundamental things

A Reaction
See Idea 14570 for the first part of this thought. This doesn't feel right. The behaviour of gravity according to the inverse square law, or General Relativity, seems to be a uniformity that extends beyond the essences of the ingredients.
