All-there-is is represented by real phenomena which can be verified and justified empirically and philosophically within a human-based framework and system of reality [FSR] or knowledge [FSK].
Whatever phenomena that is not known yet [if claimed to be possibly real] must at least be empirically and philosophically possible to be verified and justified within a FSK.
E.g. a square-circle is not empirically and philosophically possible.
A thing-in-itself is not empirically and philosophically to be real within reality - all-there-is.
Human-liked aliens in a planet 100 light years away is an empirical and philosophically possibility.
Thus what is real within reality cannot be independent of a human-based framework and system of reality [FSR/FSK].
However there are many [philosophical realists] who claimed there is "something prior" i.e. real objective reality for reality - all-there-is and all phenomena that is beyond what are perceived or appeared.
- What is that "something prior?"
Let say you saw [perception 1] a mirage of water in the middle of a desert.
But you think this is based on perception [2] of "something prior" i.e. the replication of actual water.
On more closer perception[3] the truth is the actual water is something of a liquid.
On more closer perception[4] the liquid is wet.
On more closer perception[5] using a microscope, the wet liquid is make H20 molecules.
On more closer perception[6] using an electron microscope, the cellulose molecules [H20] are comprised of 2 hydrogen and 1 oxygen atoms.
On more closer perception[7], those molecules are a bundle of generic atoms
On more closer perception[8], those atoms are a bundle of generic electrons and proton,
On more closer perception[9], there are various types quarks
On more closer perception[10], it is bundle of either wave or particle depending on how it is perceived. So, what is seemingly ultimate is not something objectively real but rather subjectively [observer's based] real.
Thereafter, we are lost and do what know what is the ultimate substance - the Objective Reality of the water we perceived[2] earlier.
As far as science is concern, it merely ASSUMEs there is an ultimate something prior, thus for science that something prior is an impossibility to be real scientifically.
So there is no other credible way we can ever find what is the real ultimate something prior that is independent of human-based framework and system of reality..
Science being the standard bearer of truth [the most credible] deny such 'other reality beyond it' exists as real and that it is impossible to be scientifically real, thus merely ASSUMES it exists.
Why philosophical realists are so desperate to reach for the 'other reality beyond it' -the impossible to be real - is due to subliminal psychological existential crisis and cognitive dissonance, else they will feel suspended and very uneasy.
I asked,
Btw, what do you gain for yourself or for humanity in insisting,
"there is an other objective reality beyond phenomena independent of humans"
