So far, so good.
Agreed. It is the action of thinking which proves an entity exists. No problem with that. How that proves that there is a singular reality that is the same for all observers is what I question. There is no evidence that the universe is so. There is plenty of evidence that people with the same basic genetic makeup will agree about how things appear. Confusing that with how things actually are is being arrogant and conceited. Why should we ever believe that the way we perceive things is the way they are? All we can objectively say is that is how they appear. That is hardly the same.
There are, I reason, 3 possibilities.
1) One entity existing in, and comprising, a singular, objective and subjective, reality (itself).
2) Multiple entities existing within a single, objective, reality.
3) Multiple entities existing within multiple, subjective, realities.
I rule out the possibility of multiple, objective realities on the basis of the impossibility of any of these independent realities being able to interact. Such a scenario might exist, but the consequence would be identical to possibilty 1) above for each observer.
In scenario 1) it is true that this singular objective reality exists for all observers, likewise scenario 2).
Scenario 3) can only exist if we cannot conclude an objective reality exists. We can conclude this - even if it can only be shown for each observer, not all observers. I exist so there is something within which I exist. This something cannot be subjective, because it is not defined by my existence but is a necessary requirement of my existence. I know that it exists as I know I exist.
Hence a singular, objective, reality exists for all observers. I consider 2) to be the more likely, but we cannot say 1) is not the reality that exists.
