“existence credibility”-The amount and the significance of sensual contact with other sentient organisms
I would say a hermit lacks existence credibility because although he could be an enlightened Taoist monk, his existence is known by much fewer than say, for example, barrack obama. Its not so much about who you are but how you live. Good and evil or both simply tactics that help to raise awareness within the universe of your own personal existence. In this case, one is not more effective than the other.
Mathew, it has to do with an organisms collective impact on the world, not how i judge it. Its how every single sentient entity that said organism has ever come into contact with judges it. You could take the quantity or the quality approach which both put you pretty high on the “e/c” scale. Again, its a ratio.
Why even have that? That sounds like a horrible idea. You’re basically judging each person’s worth by how many people they interact with. If you do it that way, you might as well say that Hitler has more worth than a mute agoraphobic hermit. I don’t think anyone has the right or power to judge the worth of anyone else other than themselves.
