Reality is that which, when you stop believing in it, doesn't go away.
Nice one. I agree.
But it's naughty of you not to give credit where credit is due: the man who said that first was every paranoiac's favourite science-fiction writer,
Philip K. Dick.
On a different note, subatomic particles don't become waves of possibilities when nobody's looking. Slight misunderstanding of the wave function
there.
Quantum uncertainty does not call the reality of our perceptions into question; it does, however, suggest that some of our inferences from those
perceptions may not be valid. But that is something quite common in the history of knowledge--it was once thought that Earth was at the centre of the
universe, for example.
As to the nature of reality, I see absolutely no reason to deny that it is what my senses (suitably augmented as required) tell me it is. Of
course, it could just be a dream I'm dreaming; but then that dream is my reality. I embrace and believe in reality as it manifests itself to the kind
of being I am. That's all the reality anyone needs.
