Madhouse

"I remember a witty Spaniard saying when, two hundred and fifty years ago, the French built their first madhouses: 'They have shut up all their fools in a house apart, to make sure that they are wise men themselves.' Just so: you don't show your own wisdom by shutting some one else in a madhouse. 'K. has gone out of his mind, means that we are sane now.' No, it doesn't mean that yet."
-Fyodor Dostoyevsky,
"Bobok : From Somebody's Diary" as translated by Constance Garnett in Short Stories (1900)
