It can reasonably be argued that “there is no objective REALITY” is a definitional impossibility. If there truly is no objective REALITY…then that IS the objective reality. No amount of subjective considerations can change that.
Let me see if I can make my point about the objective reality this way:
If the question at hand is, “Is there sentient life on any planet circling the nearest five stars to Sol?”…we can sit around and discuss the issue for as long as we want; we can introduce probability using the Drake equation or the Rare Earth equation; we can “philosophize” from here to Hell and back; we can use the opinions of common folk or scientific wonders…and can, by arm twisting and persuasion, arrive at a consensus as to whether there is or not.
But…there is an objective reality about the answer. Either there is sentient life on one of the planets circling the nearest five stars to Sol…or there is no sentient life on any of those planets...and no amount of agreement between the people discussing it can change that objective reality in any way.
That is the REALITY of that issue.
When we speak of the more general REALITY of existence…that same things holds. What EXISTS…exists; what IS…is. It may be that “what is” is that each of us has a separate REALITY; that the REALITY is like a quantum particle that changes as it is being observed; that it is static and the same for everyone; or that it is different for everyone.
But ultimately, whatever exists...is what exists.
Apparently nobody is going to change his/her mind here…and that is just fine. We are here to discuss stuff we probably cannot discuss in our non-cyber life, because the conditions for such discussions do not present themselves easily or readily.
I’m enjoying it…and I hope everyone participating enjoys it also. We are not going to resolve anything…I think we all know that. But I hope each of us is getting what we can out of the interplay.
