Thanks so much for your kind words, A-G! The Light is not "phenomenal." I've recently been struck by how closely Einstein's remark regarding reality as we experience it -- i.e., it is a "persistent illusion" -- tracks with the meaning of Plato's Myth of the Cave.... In the past you've observed that Einstein really was a Platonist, an unconscious one perhaps, even though he took the "Aristotelian side of the argument" with his friend Godel. I'm pretty sure you are right about this! :^)
