In conversation I just had, i explained why i take it that there is only one reality, and i thought it might interesting to share, since it ended up as a kind of 'proof' via reducto ad absurdom, which goes like this:
the assumption first is that 'a reality' is everything that is 'real'. i personally cannot conceive of how it could be otherwise.
the second is that there are multiple realities.
for there to be multiple realities, they must be different. we can see this if take the usual mathematical definition of a set to describe a reality.
now, take one of said realities
by the first assumption, it contains everything that is real.
therefore, everything it does not contain must be unreal
since the 'other' realities are different, they must contain SOMETHING thats not in the first reality which has 'everything real'
this then implies that all 'other' realities are not realities by our definition of 'a' reality.
the first reality is therefore the only one, contradicting the second assumption.
just wanted to share my thoughts, feel free to add your own, or challenges if you have any :)
