Ahhh, finally. Here's where everything you've said falls apart. Since you don't belief that there are absolute truths, nothing you say should be taken as truth for anyone else.
Well obviously, Felgar. And the same applies to YOUR truths. In that sense, everything doesn't fall apart, but comes together. My truths are relative as well as anybody else's. In sharing my truths, there is the chance than somebody might identify with them as well as oppose them.
Could you give me an example of absolute truth? OK, let's rule out "a priori" truths, like "It's raining outside", or 2 + 2 = 4, or something obvious like that. I think we are discussing a truth that lends itself more to subjectivity.. ("a posteriori" truths). It may be a contradiction to ask you to give me an example of an absolute, but "a posteriori" truth, but maybe you can sense what I am asking?
I chose materialism because it is as close I can get to truths which are empirical and present the least amount of subjectivity. Supernatural truths are real hard to verify and lead one into traps that can be set by people with ulterior motives. Supernatural truths are best discussed in abstract, and our day-to-day existence is usually a matter of interacting with truths that are more concrete. Truths like what time it is, what side of the road do I drive on, how much does it cost, etc. Truths like this may not be very exciting, but at least they are readily verified and don't cause a lot of endless arguing.
The abstract is fine for church, or chit-chat, or whatever, but it often remains a matter of opinion as to what defines this kind of truth. What is Love? Does your wife love you? How do you know? Is God real? Who is God? What is God saying? It's hard to escape conjecture and speculation when defining such truth. It gets into the abstract, and in many cases, you can use intuition, which oftentimes is quite valid. However it is difficult to accept someone else's intuition as verification of a truth which you don't see or understand to be true. Is the universe intelligently designed or not? How do you verify this?
Of course, the reality is that there ARE absolute truths. Unfortunately in your quest to be objective and search only for concrete reality, you have actually undermined your own capacity to accept the very reality that you are searching for.
You see? This is the very kind of vagueness that leads me to choose materialism. When you make a declaritive statement like "There are absolute truths", you have to prove it. There is nothing to accept that is not explained or verified. If anyone is undermining anything, it is YOU and you are short circuiting your right to investigate ALL truths that come your way, lest you get bamboozled or led into a dark alley.
So in your best knowledge, please give me an example of a truth that is non-relative and doesn't "fall apart" at some point.
