“You must always remain master of the situation and do what you please. No school tasks, ah, no! no tasks!”

In the Name of Sanity (1954)
Context: Today, all the normal mischances of living have been multiplied, a million-fold, by the potentialities for destruction, for an unthinking act of collective suicide, which man's very triumphs in science and invention have brought about. In this situation the artist has a special task and duty: the task of reminding men of their humanity and the promise of their creativity.

Though this has been quoted extensively as if it were a statement of Wittgenstein, it was apparently first published in A Brief History of Time (1988) by Stephen Hawking, p. 175, where it is presented in quotation marks and thus easily interpreted to be a quotation, but could conceivably be Hawking paraphrasing or giving his own particular summation of Wittgenstein's ideas, as there seem to be no published sources of such a statement prior to this one. The full remark by Hawking reads:
: Philosophers reduced the scope of their inquiries so much that Wittgenstein, the most famous philosopher of this century, said, “The sole remaining task for philosophy is the analysis of language.” What a comedown from the great tradition of philosophy from Aristotle to Kant!
