given the axiom that truth consists of the set of objective facts which determine or characterize the universe or some domain within the universe, and considering that human brains are essentially "imaginary" organs with a limited capacity to comprehend or describe the universe or more likely some much smaller subdomain of reality, it is likely that everything we think is "rational" and/or that we could expect to be "true" is probably only approximately true and probably applies accurately to an even smaller domain. . . ..
So "rational" has only a slight advantage in the claim of "truth" over our irrational notions.
I know with all our chemical fluxes coursing through our bodies there is a comforting release of some dopamine when we are satisfied with our notions, but chemistry can hardly validate merely associated neural phenomena. "Truth" is probably something beyond what we are projecting in our brains.
A babe post that I actually understand!!! Was that a blast of dopamine I just felt?
