You SURE!.. Everything just might NOT add up.. even in this paradigm.. Example: geometry is about shape.. Just maybe shape is a second reality.. And mathematics about shape is quantifing a second reality.. To wit: Mathematics is measureing a dream.. in a dream..
Could be.. at least in my primitive mind.. Does 2 + 2 = 4 ?.. yes.. in this paradigm, always, unless you're wrong..
But are we limited to this paradigm?.. even now?.. Could be some are and some are not.. Is shape an ideology?.. I say it is.. a perception.. To wit: square might be square at all.. only in this paradigm is it square.. a second reality..
Thank you for your reply! In some worldviews, I would be a figment of your imagination - as would be all physical reality.
