本文除了討論雪萊對法律本質，罪犯處罰，死刑及教育的必要性的見解外，並檢視其所關注的問題是否在英國已付諸施行。雪萊批判當時英國法律的多樣與模糊，律師的邪惡，處罰的公平性及標準等。他主張廢除死刑及教育的必要性。強調預防勝於處罰。他對當代英國法律制度的批判，無擬地可被視為一幅生動實景。在英國，罪犯處罰並沒有如雪萊所期望的加以廢除，但當今英國的法律制度，由於它的公平性、穩定性及尊嚴性，已頗負盛名，並與雪萊的見解相當吻合。

　　　　　The objective of this paper is to discuss Shelley's views on the nature of law, the punishment of crime, the punishment of death, and the necessity of education. In addition, the paper also examined whether his views are applicable to the present state in Britain. Shelley condemned the multiplicity and obscurity of laws, the wickedness of lawyers, the equality of penalties, and the criteria of punishment. He also stated that the punishment of death should be abolished and education is needed to make the law perfect and reasonable. Prevention is better than punishment. In reality, the punishment of crime has never been abolished as Shelley expected, but his views could be considered a vivid, real picture of the history of British law system in Shelley's day. The British legal system has been improved to such an extent that it now enjoys a good reputation for fairness, stability, and dignity.
