I've said this before, verbally to real people, but I'm going to set it in stone. Meaning the internet which could explode at any moment because who caches a random blog.
The glass is half-full if you have been filling the glass and stopped.
The glass is half-empty if you have been drinking the glass and stopped.
You might counter by saying that I have stumbled into a room with a glass at 50% capacity and have no way of knowing how it got to its current state.
However, to reach this state of 50% capacity the glass would have either had to be previously filled or emptied. The objective truth of how the glass reached this point exists regardless of my having witnessed it. There is an objective truth, it is just impossible for me to know.
No matter whether I was there or not, a thing happened. The universe started somehow. Will I ever know? No, because I wasn't there. But I can see its aftermath, i.e. me and everything around me, and know that some thing did occur at one point.
