Apparently when astronauts view the Earth from outer space they experience a cognitive shift in awareness. It's called the overview effect - the experience of seeing firsthand the reality of the Earth in space, a tiny, fragile ball of life hanging in the void.
I think that that's kind of like what Toni Morrison's novels do - inject immediate, transcendental awareness about the human condition. Change you forever. (Gabriel Garcia Marquez is another writer that seemed to have this power. Maybe David Foster Wallace.)
So next level. So much to process.
