Let alone how this applies to the Dickian Gnosticism we talked about just a few days ago!
Okay, this joke's totally on you! Dick (and some earlier Gnostics) essentially made the very same suggestion on metaphysical knowledge that I entertain here about social knowledge; it's an unknown known that most people already happen to possess, but which must be brought to the forefront of consciousness via a revelation event he called "Anamnesis".
I would like an answer to the tribal question I posed. Do you see how this argument applies to leftism?
As Multiheaded added, "Personal is Political" stuff like gender relations, etc also may belong here.
