Susan Sontag
Ever since reading, " Illness as Metaphor", it's been far easier to embrace sickness as a kind of religious experience than it was after reading "Science and Health with Key to the Scriptures" by Mary Baker Eddy, which teaches that disease is either a sort of delusion, a mis-alignment of one's self with the godhead, or completely non-existent.
The idea that there can actually be something good in it, feeling bad, that is to the degree that feeling bad could kill you, is mind blowing.
How fun it might've been to hear Sontag debate Baker Eddy, somewhere in New England where such things are done – perhaps Harvard –on the topic, 'are sin, disease and death real?'
