Philip K. Dick was afflicted with the consequences of too much understanding, that eventually overwhelmed his reason and caused derangement in his interactions. He did write some incredible stories, and I have much enjoyed them.
"...truth may just be more than what we simply observe..."
It is impossible for the universe to be only what I can perceive of it, as I am a very infinitesimal speck of goo without much capability to perceive the majority of the universe. There is more to what we look at than we see.
Thanks!
