He（Wittgenstein）became for a time very religious, so much so that he began to consider me too wicked to associate with. In order to make a living he became an elementary school-master in a country village in Austria, called Trattenbach. He would write to me saying: 'The people of Trattenbach are very wicked.' I would reply: 'Yes, all men are very wicked.' He would reply: 'True, but the men of Trattenbach are more wicked than the men of other places.' I replied that my logical sense revolted against such a proposition.
