AllTimeJeff -
I very much enjoyed reading your search to this question.
So to be at peace with the possibility that there is no one right universal truth (as is evidenced by the 7 billion people all over the planet, with disparate belief systems and ideas about god) leaves 2 other options. (maybe more, just my opinion.)
- There is no truth's at all, and we can be upset about that, or
- There only needs to be your truth, and it needs the approval of no one but yourself.
This is interesting to me. You start with there is not one right universal truth because of how divided people are and all the religions are...
HOWEVER: aren't there some things agreed upon in most social societies, most legal systems and even agreed upon in the all the major world religions? I would say the majority of human kind have the quite a few of the same values; the same moral truths: We all tend to agree on things such as rape, child molestation and murder as being bad. We tend to agree that the pursuit of happiness, a sense of family and love are good. If someone thinks otherwise it is generally agreed by the general population that the person who thinks differently is in the wrong. Yes: we are divided on the specifics... but, at least in my humble opinion, there are some things that ARE universal truths. Not to mention universal truths of an other nature: natural law: physics, math... etc...
My problem with your option #1 is that I don't think either of us agree with that.
My problem with your option #2 is: while most of us are moral, upstanding people (at least I'd like to believe in people) there are still the bad apples... Would you say that a person with a mental illness, or even more specifically, a person who is a sociopath/psychopath, only needs his truth and only needs his approval for that truth? Serial Killers tend to have high IQs and tend to be contributing members of society. If we base people deciding truths for themselves based on intellect then are we considering serial murders socially tolerable? Don't we have the moral obligation, regardless of creed or lack thereof, to say: "NO! His truth is not correct."????
