It appears that the true nature of reality may simply be impossible for any human mind to grasp. Even worse, it may turn out that the true nature of reality can only be understood, even at its most fundamental level, by a very tiny percentage of human minds. I say "worse" because it is is one thing to realize nature may be too subtle or complex for any human to comprehend, but it would be truly devastating to realize that others can see it, but you can't.

Human beings can do remarkable things with their minds and bodies, we are capable of interacting with physical reality to produce things of great beauty and complexity, but most of our talent appears to be subconscious, automatic, muscle memory rather than logic or intelligence. Think of a dancer or an athlete, the exquisite partnership of a man on horseback, a pilot in a plane, or a rider on a motorcycle, or a sailor on small boat. We can interact with reality and accomplish phenomenal feats, but we can't really understand how we do it, we can't even explain to anyone else how we do it.

I spent this afternoon listening to Bach's "The Art of the Fugue", by the Emerson String Quartet.
I'm not a musician, and I understand no music theory at all, but I can see what was inside JSB's head 400 years ago when he wrote those notes. I can see it, but I can't do it, I can't explain it. I can't even understand it.

"A source of Bach's power is that the meaning of his work is not abstract but inherent in the sounding music, much as Gothic cathedrals embody divine order in their use of stone and space (counterpoint was, after all, a Gothic invention). The patterns seem to suggest natural forms, the growths of cells or crystals, or the deep structures of psychology."

--Paul Epstein, in the liner notes.

I can't duplicate or even fully understand what Bach did, but I can somehow grasp it emotionally, at some deep fundamental level. I can't do that with modern physics, and that breaks my heart.
