(2nd edition), 1882.) Butler convicts Darwin of saying first that this condition was in the main the result of Selection, with disuse aiding, and in another place that the main cause of degeneration was disuse, but that Selection had aided. To Darwin however I think the point would have seemed one of dialectics merely. To him the one paramount purpose was to show that somehow an Evolution by means of Variation and Heredity might have brought about the facts observed, and whether they had come to pass in the one way or the other was a matter of subordinate concern.英文原著 · 《Darwin and Modern Science》
"Perhaps I feared to make Alphonse jealous," she interjoined, with excessive naivete. That made them all laugh. The right hand jealous of the left! The heart jealous of the soul! But for that matter, the Creole husband is never jealous; with him the gangrene passion is one which has become dwarfed by disuse.英文原著 · 《Awakening & Selected Short Stories》

The Hotel de los Extranjeros was a dreary hostelry, in great disuse both by strangers and friends. It stood at a corner of the Street of the Holy Sepulchre. A grove of small orange-trees crowded against one side of it, enclosed by a low, rock wall over which a tall man might easily step. The house was of plastered adobe, stained a hundred shades of color by the salt breeze and the sun. Upon its upper balcony opened a central door and two windows containing broad jalousies instead of sashes.英文原著 · 《Cabbages and Kings》
Use and disuse have here come into play and served to reduce the function to its present rudimentary condition. That these rudimentary organs are rarer in machinery than in animal life is owing to the more prompt action of the human selection as compared with the slower but even surer operation of natural selection. Man may make mistakes; in the long run nature never does so. We have only given an imperfect example, but the intelligent reader will supply himself with illustrations.英文原著 · 《Canterbury Pieces》
To others it has always seemed that the emphasis should be laid on Function,--on use and disuse, on doing and not doing. Practice makes perfect; c'est a force de forger qu'on devient forgeron. This is one of the fundamental ideas of Lamarckism; to some extent it met with Darwin's approval; and it finds many supporters to-day. One of the ablest of these --Mr Francis Darwin--has recently given strong reasons for combining a modernised Lamarckism with what we usually regard as sound Darwinism.
