I don't believe there are many objective truths out there. Lots of people would disagree with me on that, and have a list ready to prove me wrong with. To use a common example that I think a lot of people would agree with, I'll say:
"Murder is wrong."
This belief seems reasonable enough, I mean you do go to prison for doing such a thing, but let's question it for a moment. If someone would have murdered Hitler to save millions of lives, would murder have been wrong? Even the most obvious truths are really not that obvious. It's easy to dismiss things as true or false when you're just looking at them topically.
The more you know, the less you know, because the more you see that nearly every situation differs... especially situations involving human beings. I believe a whole lot of the world's problems as well as individual issues could be solved with this simple fact kept in mind at all times. To think that everything is a certain way, or if not that way, then this way(or "black and white") is to deny personal growth. We have a lot of silly metaphors that end up confining us. What if nothing is black or white? What if it's all gray? Red? Hell, what if it's a rainbow? What if color doesn't even exist?
You are basically throwing in the maturity towel as a human being by assuming that you know absolutely everything, or even everything about a certain subject, person(including yourself), or group of people. You may want to resist this truth with all of your might but you cannot, no matter who you are, deny that you have been proven wrong more than once in your life time. How much resistance did you present in the face of that situation? How agonizing and grueling was it to have to re-design your belief system in the face of defeat?
Why is that? Why do people hate to be proven wrong so much? It's as if they are saying, in so many words, that they despise learning new things.
All great inventors or thinkers of our generation and the ones before it had one thing in common. They questioned what they knew and what they were told. Nothing innovative would ever happen if everyone took what they were told at face value.
If everyone, collectively, decided they were done learning, and that truth as they knew it was truth, plain and simple, where would we be? Where would we go? I'm guessing nowhere fast.
What possibilities are you closing yourself off to by clinging to this metaphor? I ask you to question your personal truths, however seemingly obvious, and see what happens.
