Metaphysics is how you tune the lens settings for our reality filters. Change the underlying assumptions, while the external reality may not change - you are living and responding to a different reality than before. 

Can't really get past that. if you're lens is foggy, you're not going to get a clear representation of anything you are seeing. Problem is, the lense is multidimensional and there is no single correct orientation, but there are clearly wrong ones. You'll see an image, but the experienced photographer can infer the settings of the filter.
