君主たるもの良くない人間になり得ることを学ぶべきであり、必要が命ずるときはそれを実行する覚悟が必要である、と説いたイタリアの政治思想家ニッコロ・マキャヴェッリ（1469-1527年）。本書は『君主論』をはじめとする著作にみられる思想をじっくり検証する手ごろな入門書です。改訂新版は『君主論』で議論されている君主として権力を保持し続けるにはどのような「ヴィルトゥ（徳、技量）」が必要かについて、キケーロやリウィウスら古代ローマの倫理学者・歴史家からマキャヴェッリが受けた影響について新たな考察を加えています。(cf.

Niccolò Machiavelli taught that political leaders must be prepared to do evil so that good may come of it, and his name has been a byword ever since for duplicity and immorality. Is his sinister reputation deserved? In answering this question Quentin Skinner traces the course of Machiavelli's adult life, from his time as Second Chancellor of the Florentine republic, during which he met with kings, the pope, and the Holy Roman Emperor; to the fall of the republic in 1512; to his death in 1527. It was after the fall of the Republic that Machiavelli composed his main political works: The Prince, the Discourses, and The History of Florence. 
    
In this second edition of his Very Short Introduction Skinner includes new material on The Prince, showing how Machiavelli developed his neo-classical political theory, through engaging in continual dialogue with the ancient Roman moralists and historians, especially Cicero and Livy. The aim of political leaders, Machiavelli argues, should be to act virtuously so far as possible, but to stand ready 'to be not good' when this course of action is dictated by necessity. Exploring the pivotal concept of princely virtù to be found in classical and Renaissance humanist texts, Skinner brings new light to Machiavelli's philosophy of a willingness to do whatever may be necessary - whether moral or otherwise -to maintain a position of power.
