本文以司馬遷與班固所記錄的西漢游俠為研究對象，分成四章進行討論： 第一章考察先秦到兩漢之間，有關「俠」的詞彙，歸納「游俠」概念的轉變與擴充，以及各個詞彙的運用時代。然後討論司馬遷、班固與荀悅描繪游俠的立場；接著整理所有游俠的個案後，認為西漢游俠是具有交友或養客、干犯法禁、助人於危難等行為的人。 第二章講述從家庭、宗族到社會的眾多型塑游俠性格的因素，進而了解游俠在構築人際網絡時，如何於鄉里、官場中，採取各種手腕來展露個性、博取友誼與名聲，並分析這些人際關係的性質。 第三章討論游俠們生長分布的環境特性，以及他們踏入社會後，受限於身份的貴卑，運用不等同的資源來遠行、遷居，造成了他們的活動範圍極限也相異的現象，並附帶討論俠名的傳播。 第四章分析西漢社會中，統治階層內的不同身分者，他們對游俠抱持的觀感，和游俠的應對之道；次論西漢統治階層內部的變化，對游俠所產生的影響。最後檢討政府的法律規範，與其他治俠方策的成效。 總括而論，西漢游俠是承繼先秦沒落貴族的遺風，保存尚武重義的精神，即使後世游俠漸衰，行徑卻在大眾之間不時展現。 This article is talking about the arrant knight in early Han Dynasty witch Sy Maa-Chian and Ban Guh had been mention.
