In quantum mechanics, the Heisenberg uncertainty principle states that certain
pairs of physical properties, like position and momentum, cannot both be known
to arbitrary precision. That is, the more precisely one property is known, the
less precisely the other can be known.
I had some seemingly wise insight into good vs evil to go along with the uncertainty principle but my brain is not working for me very well tonight so you will just have to wait. It had something to do with not being able to know with any certainty whether the consequences of an action, be they judge good or evil, will turn out in the same direction has the original action. By that I mean just because an action is judge to be a good action now doesn't mean that the eventual outcome of that action will have good results.
Any way this is all you get for tonight. Maybe some other day I can come back and fill this in a bit more.
