"Mmmm... on Mars, when we needed to know anything - anything at all - we could consult the Old Ones and the answer was never wrong.  Jill, is it possible that we humans don't have any 'Old Ones?' No souls, that has to mean.  When we discorporate - die! - do we die dead? die all over and nothing left?  Do we live in ignorance because it doesn't matter?  Because we are gone and not a rack behind in a time so short that a Martian would use it for one long contemplation?  Tell me, Jill.  You're human."
