Tractatus Pathetico-Poeticus [6.53]

6.53 The proper mandate of poetry would ideally be the following: to say nothing except what can be said, i.e., the sentences of cultural politics--i.e., something that has nothing to do with poetry--and then, whenever someone wanted to say something anthropological, to demonstrate to him that he had failed to strip certain signs in his sentences of meaning. Although it would not be satisfying to the other person--he would not have the feeling that we were teaching him poetry--this mandate would be the strictly proper one.
