"與肌肉運動有關的",1841年,來自希臘語 kin ē tikos "運動的,使運動",來自 kin ē tos "被移動",是 kinein "移動"的動詞形容詞(來自 PIE 詞根 *keie- "使運動")。
Buster Keaton's subject was kinetic man, a being he approached with the almost metaphysical awe we reserve for a Doppelgänger. This being was, eerily, himself, played by himself, then later in a projection room, watched by himself: an experience never possible to any generation of actors in the previous history of the world. [Hugh Kenner, "The Counterfeiters," 1968]
巴斯特·基頓(Buster Keaton)的主題是動力人,一種他以幾乎形而上學的敬畏之心來接近的存在,我們爲之保留了對於 Doppelgänger 的敬畏之心。這個存在是他自己,由他自己扮演,然後在放映室裏,由他自己觀看:這是任何一代演員在世界歷史上以前的任何時候都不可能經歷的體驗。[休·肯納(Hugh Kenner),《僞造者》,1968年]
