Earnest, I didn't know that synesthesia was that common...I'll drive more carefully now
Plato's Allegory is very much to the point here, thanks for that link: a very thought-provoking examination that opens up a whole lot of self-analysis. And yes, you are anticipating my next proposition, so let's go:
Proposition 2: Everything we "know" is nothing more than someone else's interpretation.
Purport: Every self-determination we make is based on non-truth.
"Well now, Craig, what you say about self-determination at least offers a positive idea about our personal self-worth, and dignifies our moral right to make decisions for ourselves. But here you turn around and say that those very decisions are misinformed? How is that "good?" And what's more, I'm learning new things every day; I'm far from ignorant, and to suggest that I am ignorant is just plain insulting!"
The "misinformation" of which I speak has nothing to do with how many "facts" we accumulate, or how much understanding we have, or how much experience we've had. It has to do with how we think and learn. For example, take a newborn baby, fresh out of the womb. We lean over, smile, and say "Oh, aren't you just a cutie?" What does that baby think about that? Nothing. Our facial expression means nothing to him, our words mean nothing to him. Or, we show the baby a congratulatory card we got from a friend. What does the picture on that card mean to the baby? or the writing on that card? Nothing, because the baby has not yet developed the ability to associate meaning with abstract symbols in the world around him. He has no "ideas" in his mind, he's a blank slate.
How then does that baby develop ideas? All the people around him superimpose their own perceptions on that baby! For example, we say the word "chair," and gesture toward that object with which we have associated that symbol (i.e., the "word" chair), and so then the baby also associates that symbol with that object. But it's not his definition or perception, it's ours. Eventually, that baby accumulates more and more such associations; for example, he learns that those inkblots on a piece of paper are not just random patterns, but are symbolic letters, and that those letters combine together to form symbolic words, and as he absorbs more and more words (all of which are nicely defined for him in a handy dictionary), his thinking processes get increasingly complex. All kinds of abstract associations form in his mind, and eventually he becomes "smart;" ahhhh, he's finally thinking for himself.
In fact, he never starts thinking for himself! His entire perception of the universe is nothing more than a reflection of the thousands of interpretations and meanings of symbols that have been superimposed on him by others. What he calls "truth" is nothing more, and nothing less, than somebody else's idea of what truth is.
And it can never be any other way. That is the standard (or moral) of our existence.
To tie this in with the topic that started all this: No JW is less "informed" than any of the rest of humanity. The "reasons" each and every one of us accept as our own fall equally short of being "truth."
