Picture the moment after someone lets go. A door with a spring closes on its own; nobody is pushing it. Something set up beforehand is now running the next step, so the human hand is out of the picture — not because the person is absent, but because their choosing is no longer part of it. Every use of `automatic` is that same missing hand: in a machine, in a rule, in a habit.

automatic 可以想成「手放開之後」的那一刻。裝了彈簧的門自己關上,沒有人推它;事情之所以繼續走下去,是因為有人事先把它裝好了,所以現在這一步不需要有人再決定一次。人不見得不在場,只是他的「選擇」已經不參與了。機器、規定、習慣,這個字用在哪裡都是同一隻消失的手。

From the word’s history

From Greek automatos, autos "self" plus a root meaning "thinking, animated" — literally acting of itself. English took the adjective in 1812 for things "self-acting"; the machinery sense follows in 1850, and the nouns are recent: automatic weapon 1902, car with automatic transmission 1949.

automatic 來自希臘文 automatos:autos 是「自己」,後半的字根有「會動、有心思」的意思,合起來就是「自己動起來」。英文 1812 年借來當形容詞,指「自己會動的」;1850 年才專指機器,名詞用法更晚——自動武器 1902 年,自排車 1949 年。所以「不用人動手」一直是這個字的中心,後面的意思只是換了場景。
