Easy.
Truth is what is Objectively Real.
Our job is to clean the lens of perception, to network, to contrast and compare and thus build up an internal map of the Objective Reality around us.
One of the things I like about the C's message is the confirmation that Objective Reality is, well, Objectively Real.
This IS an article of faith, and that's fine by me. We all need a Religion, and mine is the belief in Objective Reality.
Believing this allows me to side step the swampy shadow world of two-bit philosophers who use word games and mental buggeryboo to hide from the work of dealing with life.
It's a huge load off! It's an eternal spring of energy and solace!
Having some jackalope who tries to drag me down into their swamp of perpetual befuddlement is easy to flick away because, guess what? The premise that, "Oooooh, reality isn't really there. You can't proooooove it! Everything is subjective! Everybody's personal reality is right!" is just plain navel-gazing foolishness.
As I build out my map of Objective Reality, I become stronger and more powerful. More than once I have, from a deep place of contentment and certainty, brushed aside frail philosopher trolls, leaving them wondering. Until that point, they were able to batter the sanity of others, crush the self-confidence of the uneducated! This is their special power; to dissolve other's sense of reality, to cast them into doubt and fear. To defeat others!
But.., why, oh, why does it not work on him (me)?
I had one such feverish fool become obsessed with me after we had a long discussion and he discovered that none of his tricks worked. I had reasonable answers to all his bullshit. I was accomplished in science knowledge. In reason. In all sorts of areas. I wasn't hiding behind dogma or simplicity or stubborn ignorance. I thought about his questions, found them interesting, and pointed out their weaknesses. He was baffled! "That guy is really confident. He is happy! He is more powerful than me! How does he do that? I must follow him like a lost lamb!"
Psh. Sorry, bub! Brushing off such wraiths is also just as easy as blowing away their swamp gas. The discussion (or series of them) was the lesson. Now go work with what I've explained and leave me alone.
Of course.., the path to truth does involve knowing that your internal map isn't going to be perfect, that you need to constantly update it and accept that your assumptions may be wrong. But when you know that you're building on God's firmament, you've got solid ground to push off from with each step.
I found my faith, baby! I believe that Objective Reality exists, and gosh, it sure seems to work out nicely whenever I apply that base assumption.
Life is Religion.
