Given that we exist in a universe that manifests itself in concepts such as relativity and quantum mechanics, I would question if there is an objective reality, or is it dependent on our participation and observation for its existence and direction, so that it exists at least in part subjectively.
Like the uncertainty principle with regards to a particle, where we can know its velocity or position, but not both, as the act of observation / measurement alters the particles' properties. Therefore, it could, but not necessarily would, be the case that our active involvement in reality, affects reality and perception, and could mislead us into thinking that our subjective experiences are in fact independent objective entities that exist of their own volition.
How could we know the difference?
How could I possibly know that my experience of reality is the same experience that everybody else has?
Yes, it is generally accepted that for the most part we experience reality through our five senses. But this leaves out other possible sources of information.
Who can definitively deny the reality of revelation, when the acquisition of such knowledge can not be demonstrated or tested?
Such testing already assumes a mechanistic overview of reality, and disallows the possibility of fluidity and a more clustered and less homogeneous state within which we exist.
