No two persons have identical experiences. I see you, and you see me. I experience you, and you experience me. I see your behavior. You see my behavior.
Natural science knows nothing of the relation between behavior and experience.
That is to say it is not a scientific problem. There is no traditional logic to express it. There is no developed method of understanding its nature. Valorizing scientific objectivity is also a choice made by a people at a particular stage in its history. And then when we both find out that we pretty much agree on its meaning, but you still don't explain why Scientism should enter into the argument.
