Reality is only one thing. There aren't many and various realities! Subjective belief, yes; reality? No.
There is concrete reality and philosophicla reality and subjective reality.
Reality is what is. It is accessible by all regardless of opinion or point of view.
Yes.
You can tell a blind person in a room there is a chair in the middle of his path. When he reaches the spot your words will either be proved true
or false.
Yes, but if he misses the chair, doe sit make reality false or his perception of reality false?
Playing around with reality could only really be changing your mind opinion-wise. What we think does NOT impact on real things.
Of course it does, how can you say it doesn't?
Do you k now why we fly? because someone thought that, against reality, we could.
You can, for example, think "this gun is not loaded". Go ahead and pull the trigger. That is Falsifiability! What happens within reality always has the last laugh on our opinion of reality.
100 years ago the reality was the a "virgin birth" was NOT reality, and here we are now, in a different reality where, if a virgin wanted to have a child, she could, quite easily as a matter of fact.
50 years ago, running the 100 under 10 seconds was not reality, no way it was humanly possible and yet, here we are in a time where running under 10 seconds is common place in elite level competition.
Reality is subjective to our perception and our place in time.
Certainly certian realites are concrete- we all die for example, yet we shouldn't believe for a minute that O UR reality of today will be the reality of tomorrow.
