Is it your belief that human perception could function without time and space?
If a human nervous system perceiving time and space was altered, by the motion of a scalpel or projectile through space, would the perception not be affected or even terminated?
If the arrow of time did not exist except in human perception, would neurons even be able to metabolize sugars, releasing energy to enable the reactions of transmitters across synapses? What would it mean for a potential to travel along the neural membrane, and for the synaptic gap to clear after the synapse fired? How would the signals that are perceived be processed?
Is the ongoing fusion reaction in the sun, which is the source of energy for practically all life on earth, a human perception? Would plants do photosynthesis if no humans were there to witness it?
I'm not here to invalidate your beliefs, but very curious how such a radically idealist world-view addresses questions like the ones I asked.
I appreciate a philosophical line of questioning like this one.
I believe time and space belong to the corporeal plane. We can't function without them as incarnated humans, and space is a big part of the corporeal plane.
Physicists dispute the notion of time in some theories, so to speak. The events we observe in the universe are a form of time travel, and space travel itself would be a form of time travel if we went to the next solar system and then back to Earth. Time does play a big role in the corporeal plane, but contemporary science indicates such role may be more fluid than our everyday strict notion of time.
Anyway, the spiritual plane operates in different conditions, in which time and space as we know them don't exist (which doesn't necessarily mean that they don't exist in another form, as part of a different dimension). Our true selves, our souls, are free from the restraints of the corporeal plane when our bodies die, and thus aren't subject to time and space as we know them. That's what I meant.
Plants have their own souls and their own purposes in God's creation (from a human perspective, it's mostly to feed us and other animals). I'd rather think they'd still exist and do their own business if humankind wasn't around, since they were on Earth long before we came to be and may as well continue existing here if (or when) we stop reincarnating. Maybe God didn't create life exclusively in places where there's self-aware life. Maybe we'll find planets that are strictly jungles, with nothing but plant life.
