Yeah, The Common Law has been in print since 1881 where we see "felt necessities of the time" show up.

And while it does feel uncomfortable to think that the laws of the land just come from what amounts to low to high levels of mass hysteria, it also means that we can enact and/or ignore/repeal laws which just don't work.

Imagine a law which looks good on paper and is "proved" to be "good" with stringent mathematical underpinnings, but which fails to serve the people due to some higher order outcome which we simply do not have the cognitive or mathematical understanding to explain. You had better hope that "felt necessities of the time" lets us do something else.

[Of course 'felt necessities of the time' can also do some really messed up stuff. I have no defense. I only argue that just because something happens due to feelings or mass hysteria instead of reason, mathematics, or logic doesn't mean it has to be bad. The feelings or hysteria might be coming from some issue which we cannot otherwise verbalize.]

Well, shouldn't, I guess.

It should if we still want to call representatives representatives. If it's truly safe, then the discrepancy between feelings and reality should be addressed in good faith.
