  1. Focused on " understanding media ", the article analyses in chapter i the key media theory of employing what could be of mcluhan in a thoughtful angle , and advances the viewpoint of " human being - the extending of media ? ". in chapter ii 、 in the following third part , the idea of " media ' s endding " is expounded and demonstrated , which is composed of three parts : extreme of speed , content of the content , and human being ' s last extending - the extending of central nerves 。 in the final part , the general conclusion ? ? electronic media ' s influence on human behavior is given , that is human are under universal narcissism and pacing to the bottom of it impelled by electronic speed. the article has five original points in it : first of all, in virtue of " content theory " , it analyzes the theory of " meida equals to information " by mcluhan from a scale theory stand. secondly, the tremendous power of electronic media is emphasized from an implosion view. in the third point, the article advanced originally that, after extension of central nerve system, human themsevels reverse to an extension of media and turns into a node of it ; at the same time, the article proposes that, all extensions before that of central nerve are " controllable extension ", however, it reverses to " uncontrollable extension " while extending ; then the authur put forward for the first time that, the concernful reason obsessing human is the failure of their in - body central nerve system " s jointing and controlling on out - body central nerve system naturally. 。 the fourth point is, the article demonstrates systematically the idea of " media ' s endding " from three levels solely by thoughtful means, and this is the most revolutionary point of it all

    論文的創新之處有五點:一是從「尺度論」的角度,藉助「內容論」來解讀麥克盧漢的「媒介即訊息」的思想;二是從「內爆」的角度突出電子媒介的巨大力量;三是獨創提出在電子媒介時代,人類延伸了自己的中樞神經系統之後,人類本身被逆轉為媒介的延伸,成為電子媒介的一個節點;同時在本章節中提出中樞神經延伸之前的所有延伸為「可控延伸」 ,而中樞神經被延伸時「可控延伸」逆轉為「不可控延伸」 ,並首次提出,困擾人類種種問題的重要原因是體內的中樞神經系統縫地接和控制被延伸出去的體外中樞神經系統;四是獨自運用思辯的力量從三個層面綜合論證了「媒介的終結」的觀點,此處論證為本文最大創新之處,而此結論也將具有重大的理論與現實意義;五是根據以上幾個部分的論述,人類目前的總體狀態作了一個性的判斷,即:我們這個時代的迷惘在於我們深陷於自戀的漩渦里難以自拔,在電子媒介以其固有的電力速度的推動下,我們走自戀的盡頭。
