Hi HF;
I understand your point and apologize if I misinterpreted your view. Ones beliefs of reality, I think, are based on ones perceptions. I know of no other way of assimilating the physical universe.
Even though we can touch, see and taste something through our perceptions, how do I , without a doubt, know it's any more real than an idea I have.
All the data we have in our I/O brainbox is based on perceptions we have picked up over a lifetime.
Thanks for a lively discussion. All the best to you.
Jeff
