If you mean my example using people who were born blind, I meant that much like they develop their own system and theory to identify what they cannot sense (visible space), so do all humans in regards to identifying how the external world/the cosmos functions. It isn’t about which one is “less real”, unless we claim that there is one being (or one group of beings etc) which witness an actual reality. That itself is highly debatable (eg Descartes, and some other thinkers, usually reversed such a role for a deity).
I don’t understand how the heard world is less real than the seen world.
