<注釋>The wordsautomatic pilot or automatic transmission bring to mind mechanical devices that operate with minimal human intervention. Yet the wordautomatic, which goes back to the Greek word automatos, .acting of one`s own will, self-acting, of itself,. made up of two parts,auto-, .self,. and -matos, .willing,. is first recorded in English in 748 with reference to motions of the body, such as the peristaltic action of the intestines: .The Motions are called automatic from their Resemblance to the Motions of Automata, or Machines, whose Principle of Motion is within themselves..Although the writer had machines in mind,automatic could be used of living things, a use we still have, although not the primary one. The association ofautomatic chiefly with machinery may represent one instance of many in which we have come to see the world in mechanical terms.
這些單詞automatic pilot 或 automatic transmission 帶給我們只需最小人力介入即可操作的機械裝置的意識。 但這個詞automatic， 追溯至希臘單詞 automatos， .以個人自身的意志行動，自我行動，. 由兩部分組成，auto-， .自我的，.和 -matos， .意愿，. 以作為身體運動的含義于748年首次記錄于英語，如體內(nèi)的腸蠕動： .這些運動被稱為身體內(nèi)自動的運動，是與機器運動的相似性得出的，其運動原理在于其自身內(nèi)部。.雖然作者頭腦中有機器印象，automatic 可以被用于生物，這種用法雖然不是基本的，但我們?nèi)栽谑褂谩?主要將automatic 與機器相聯(lián)系可能反映了我們眼中的世界越加機械化的情況
