Fyodor Dostoyevsky,
The Brothers Karamazov
(1880)
“ I mean an afflicted idiot, formerly the servant, and possibly the illegitimate son, of Fyodor Pavlovitch, Smerdyakov. At the preliminary inquiry, he told me with hysterical tears how the young Ivan Karamazov had horrified him by his spiritual audacity. ‘Everything in the world is lawful according to him, and nothing must be forbidden in the future—that is what he always taught me.’ I believe that idiot was driven out of his mind by this theory, though, of course, the epileptic attacks from which he suffered, and this terrible catastrophe, have helped to unhinge his faculties. ”
