John Deigh's new volume of previously published essays covers expansive ground—from moral psychology to the history of ethics, from James, Nietzsche and Freud to Hume, Sidgwick, and Strawson. Fully one quarter of the book, however, explores the philosophy of punishment. Deigh's dominant concern in this portion of the book is to develop and defend a novel principle of proportionality in punishment, one which provides that the severity of just punishment is a function of the damage the offense threatens or inflicts on the civil order. That is a welcome project, for philosophers of punishment widely agree that proportionality remains an elusive concept. Yet whether Deigh has solved the puzzle is uncertain. This essay raises doubts and sketches an alternative solution.

比例惩罚原则：对约翰·戴格的评论，从心理学到道德：伦理自然主义论文集

John Deigh 之前发表的新论文集涵盖了广阔的领域——从道德心理学到伦理史，从詹姆斯、尼采和弗洛伊德到休谟、西奇威克和斯特劳森。然而，整本书四分之一的篇幅探讨了惩罚的哲学。Deigh 在本书这一部分的主要关注点是发展和捍卫一种新颖的惩罚相称原则，该原则规定公正惩罚的严重程度是犯罪威胁或对民事秩序造成的损害的函数。这是一个受欢迎的项目，因为惩罚哲学家普遍认为相称性仍然是一个难以捉摸的概念。然而，Deigh 是否解决了这个难题尚不确定。这篇文章提出了质疑，并勾勒出另一种解决方案。
