Okay, an intelligent R&S question?

The ancient Greek philosopher, Plato, believed in a Theory of Forms, that everything in the "real world" is just a shadow of something that exists in a supernatural dimension, a dimension we can only access though our minds. So, for example, the love and beauty that we humans perceive on Earth are just shadows (or reflections) of a perfect, universal love and beauty that would exist whether humans existed or not. Christianity picked this idea up and turned it into a spiritual phenomenon, that there is a "perfect" world beyond this world we live in. Whether you're religious or not, could you believe that we on Earth experience an imperfect, flawed existence, and that there is a perfect "world of the mind" which we can access only through renouncing the physical, material world we actually live in?
