Reality vs Delusion" Reality can only be realized through rational thought & reasoning. However, that reasoning must be based solely on whats really there & that isn’t always easy. "
Well R v D, I think it's a happy coincidence, your avatar name. As for its appearance, your description is quite amusing and close to my slightly warped view.
I think I mostly agree with you about perception with one major difference: the way we achieve or determine reality. You say:" Reality is not a perception, an idea, or a belief. Our personal understanding, knowledge, and feelings are simply NOT reality. They are only our limited understanding, our limited knowledge, and our feelings " and "Reality is simply fact and is beyond our personal perceptions and feelings". My major fundamental concern is that reality, whatever it is, is limited to how we attain it. I mean that in a very profound sense as well as in everyday life. Here's one example:
I have a recurring pleasant reality when I pet my tiny fuzzy dog. But along with other capabilities, I have determined that I have never done anything like pet my tiny fuzzy dog. Petting involves touching and atoms do not actually touch. So my perception of touching, softness, warmth, smooth or rough does not involve the experience of my atoms "mingling" with other atoms. It has more to do with the secondary effects of forces I don't fully understand operating on my atoms and causing tertiary waves that my brain interprets as touching, softness, warmth, smooth or rough. Moreover, I can actually experience the exact same sensation without actually petting anything. I have done so many times with other sensations in my dreams and it seems just as real.
But for a slight condition in our brains (like not being able to feel pain), our reality is severely altered. CIPA (Congenital Insensitivity to Pain with Anhidrosis) is a rare genetic condition that makes the bearer unable to feel pain, heat, cold or even the urge to pee.
As we move in complexity up the world line, reality is even more subject to our limited perceptions. Imagine if we could see the world in the entire range of light spectrum. Our reality would be significantly different. What I'm suggesting is that while we share a great deal of commonality in our share reality, there are variances, subtle and not so subtle, that affect that reality.
I think you're right in saying that "Reality can only be realized through rational thought & reasoning". That is precisely an indicator that reality is not always correct by virtue of our perceptions. With reasoning we can possibly come to a more accurate understanding of what reality is. If we just hold to what we observe we are giving in to our person delusions, the ones that cloud our perception of what we would like to know is true and real.
I'm suggesting that as a species, we have limitations and that as individuals we have a nuances that affect our view of the world (reality). Even with the deepest kind of reasoning, it may still not be possible to determine what the nature of the world is, in a literal sense. We have not yet determined whether light is a particle or a wave or both. We can't determine where an electron is and if we do, we know nothing about its state; we can't determine the nature of matter at all. Yet, we assume something and go on.
I was a Mathematics major in college and was blown away when my Calculus professor proved, using the basic rules of addition and subtraction that 1 + 1 = 3 (given a=b and a=1 so b=1). I know that it's based on a mathematical fallacy. But you can't tell that using notation and can only know after substituting for real values. Even so, there are a lot of mathematical oddities that push the boundaries of reason. Math is not a natural science and therefore is not subject to the same rules of verification. In the observable world, however, we must constantly test our observations in order to determine what is real. Why? Because what we think is real sometimes is not.
