“As the strata of the earth preserve in succession the living creatures of past epochs, so the shelves of libraries preserve in succession the errors of the past and their expositions, which like the former were very lively and made a great commotion in their own age but now stand petrified and stiff in a place where only the literary palaeontologist regards them.”

"On the Tendency of Varieties to Depart Indefinitely From the Original Type" (1858).
Context: The powerful retractile talons of the falcon- and the cat-tribes have not been produced or increased by the volition of those animals; but among the different varieties which occurred in the earlier and less highly organized forms of these groups, those always survived longest which had the greatest facilities for seizing their prey. Neither did the giraffe acquire its long neck by desiring to reach the foliage of the more lofty shrubs, and constantly stretching its neck for the purpose, but because any varieties which occurred among its antitypes with a longer neck than usual at once secured a fresh range of pasture over the same ground as their shorter-necked companions, and on the first scarcity of food were thereby enabled to outlive them. [... ] We believe we have now shown that there is a tendency in nature to the continued progression of certain classes of varieties further and further from the original type - a progression to which there appears no reason to assign any definite limits - and that the same principle which produces this result in a state of nature will also explain why domestic varieties have a tendency to revert to the original type. This progression, by minute steps, in various directions, but always checked and balanced by the necessary conditions, subject to which alone existence can be preserved, may, it is believed, be followed out so as to agree with all the phenomena presented by organized beings, their extinction and succession in past ages, and all the extraordinary modifications of form, instinct, and habits which they exhibit.

A Battle For Life (July 1958)
Context: Later the assistant chief surgeon told people that he had been a surgeon for eleven years, had seen not a few patients die and consequently had become quite cold and indifferent. He was interested only in diseases as such and had no feelings for his patients as people. But what Chiu Tsai-kang had said impressed him deeply. Even after he left the patient's room he thought it over for quite a long while. Here was a man awaiting death who had to clench his teeth to endure the searing pain of his whole body, but who constantly had the nation's steel production on his mind and who wholeheartedly desired to return to his furnace. In the past, he had read of people with such public spirit and unselfish character only in novels. He had regarded them as nothing but ideal, imaginary creations of literary writers. Now he has seen such a hero in the flesh with his own eyes.
