Many of the above are strawman[s] to the OP.
I wrote in the OP:
"Here is reference where Science merely assumes the existence of a mind-independent external world, i.e. external objective reality which is
unprovable by Science itself'; ..."
Assumptions be can of the following;
- 1. Proven scientific facts
2. Provable scientific facts - empirically possible
3. Unprovable by science
4. Fictions
5. Contradictions
6. Whatever that can be thought
If I assumed [in a thesis] there are
human-like aliens in another
planet 10
light years away, this is verifiable, justifiable and provable by science. Since the variables are all empirical, it is a matter of providing the empirical evidences for science to verify, justify and prove whether it is scientifically real via a human-based scientific FSK.
As such whatever the thesis in confirmed, it is limited by the assumption, but it is nevertheless possible to be real conditionally.
But in the case of Science, esp. Newtonian and Einsteinian Physics, science assumes
the existence of a mind-independent external world.
Science itself admit this external objective reality is
unprovable by science, so, it has to be assumed. [note unprovable to be emphasized]
Philosophical realists insist, while it is unprovable by science and unknowable by science, this
assumed mind-independent external world is nevertheless REAL!
The point is
'what is REAL' is conditioned to a human-based FSR-FSK of which the human scientific FSR-FSK enable the most-realistic* emergence and realization of reality.
"What is real" on a FSR-FSK basis comes degrees depending on the credibility, reliability and objectivity of the specific FRR-FSK. e.g. the scientific-FSK @ 99/100 [most real]; the p-realist FSK @ 10/100, the theistic FSK @ .1/100.
- 1. what is most real via FSR-FSK is human-based,
2. Human-based involved humans, body, brain and mind
it follows deductively,
3. what is most real is conditioned upon humans, body, brain and mind
As such, what is most real CANNOT be unconditioned upon humans, body, brain and mind, i.e.
thus what is most real CANNOT be CANNOT be mind-independent.
Philosophical realism claims that reality and things are mind-independent.
Therefore philosophical realist is not realistic [most real].
Philosophical realists insist, while the
assumed mind-independent external world even if unprovable by science and unknowable by science, this
assumed mind-independent external world is nevertheless REAL!
On the contrary, as demonstrated above, the assumed mind-independent external world even if unprovable by science and unknowable by science, CANNOT and is impossible to be REAL [most FSK-ed real].
