Right now, necessarily so.

The more mysteries that science solves, the more we unweave the rainbow*, the worse the tension between rationality and our sense of what we are. Am I the atoms, or the pattern betwixt? Am I the present moment alone, my memories mere shadows of past patterns and my current form doomed to be a shadow to a future pattern of these self-same atoms?

Sometimes even the question is unbearable.

There are many mysteries of the universe, but who we are, to the extent that I am rejecting the comment I replied to, is not one of them. I would love to see how humans explore reality and being (if we survive!) as time goes on and we figure more out, but I hope we do so as a whole species and not through the designs of a handful of zealots.
