Two unverifiable beliefs. What is it you are missing?
Ah. What can we say that we "know" at all. How much is, as Kant styled it, the "already out there now real" and how much is our imposing a structure on reality? And what about those things that we have to change even to be able to observe them in the first place?
And "time," what's with that? Did you ever notice how our perception of time can be altered significantly by the chemical composition of our blood? Is it more than just football jargon that the game "slows down" for the great quarterbacks? Is there something about how they interact with reality that's different than others? Same for the great hitters in baseball who say they can see the seams on the ball almost stop rotating as it comes to the plate
Our very perception of reality is largely a complex set of assumptions that we weave together in a familiar manner.
I once had a brilliant (but marginally sane) Philosophy Prof, who posed this scenario: "Now suppose, Mr. X, that you had kept a parakeet in your home for a year or so, feeding and caring for it. Then, one day, in front of your eyes, it exploded. What might you conclude? Would you conclude that it was not a parakeet in the first place or that you now know something new about parakeets, namely that "they explode?'"
I stopped studying Philosophy and got an MBA, but I've never been able to answer that question, with all its ramifications, to my satisfaction.
Maybe I should just blame this post on 4/20?
