Context: Science cannot be stopped. Man will gather knowledge no matter what the consequences – and we cannot predict what they will be. Science will go on — whether we are pessimistic, or are optimistic, as I am. I know that great, interesting, and valuable discoveries can be made and will be made… But I know also that still more interesting discoveries will be made that I have not the imagination to describe — and I am awaiting them, full of curiosity and enthusiasm.

Book XXIII, ¶ 7,as rendered in the epigraph to Ch. 3 of The Lathe of Heaven (1971) by Ursula K. Le Guin, based upon the 1891 translation by James Legge, Le Guin was subsequently informed that this was a very poor translation, as there were no lathes in China in the time of Zhuangzi. The full passage as translated by Legge reads:
He whose mind is thus grandly fixed emits a Heavenly light. In him who emits this heavenly light men see the (True) man. When a man has cultivated himself (up to this point), thenceforth he remains constant in himself. When he is thus constant in himself, (what is merely) the human element will leave him, but Heaven will help him. Those whom their human element has left we call the people of Heaven. Those whom Heaven helps we call the Sons of Heaven. Those who would by learning attain to this seek for what they cannot learn. Those who would by effort attain to this, attempt what effort can never effect. Those who aim by reasoning to reach it reason where reasoning has no place. To know to stop where they cannot arrive by means of knowledge is the highest attainment. Those who cannot do this will be destroyed on the lathe of Heaven.
