“Just as we cannot stop the movement of the heavens, revolving as they do with such speed, so we cannot restrain our thought.”

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.

A Propos of Lady Chatterley's Lover (1929)
Context: We are today, as human beings, evolved and cultured far beyond the taboos which are inherent in our culture. This is a very important fact to realise. Probably, to the Crusaders, mere words were potent and evocative to a degree we can't realise. The evocative power of the so-called obscene words must have been very dangerous to the dim-minded, obscure, violent natures of the Middle Ages, and perhaps are still too strong for slow-minded, half-evoked lower natures today. But real culture makes us give to a word only those mental and imaginative reactions which belong to the mind, and saves us from violent and indiscriminate physical reactions which may wreck social decency. In the past, man was too weak-minded, or crude-minded, to contemplate his own physical body and physical functions, without getting all messed up with physical reactions that overpowered him. It is no longer so. Culture and civilisation have taught us to separate the reactions. We now know the act does not necessarily follow on the thought. In fact, thought and action, word and deed, are two separate forms of consciousness, two separate lives which we lead. We need, very sincerely, to keep a connection. But while we think, we do not act, and while we act we do not think. The great necessity is that we should act according to our thoughts, and think according to our acts. But while we are in thought we cannot really act, and while we are in action we cannot really think. The two conditions, of thought and action, are mutually exclusive. Yet they should be related in harmony.

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.
