Every modern democratic state imprisons thousands of offenders every year, depriving them of their liberty, causing them a great deal of psychological and sometimes physical harm. Relationships are destroyed, jobs are lost, the risk of the offender being harmed by other offenders is increased and all at great expense to the state. How can this brutal and costly enterprise be justified? Traditionally, philosophers answering this question have argued either that the punishment of wrongdoers is a good in itself (retributivism), or that it is a regrettable means to a valuable end, such as the deterrence of future wrongdoing, and thus justifiable on consequentialist grounds. This book offers a critical examination of those theories and advances a new argument for punishment's justification, calling it the 'duty view'. On this view, the permission to punish offenders is grounded in the duties that they incur in virtue of their wrongdoing. The most important duties that ground the justification of punishment are the duty to recognize that the offender has done wrong and the duty to protect others against wrongdoing. In the light of these duties the state has a permission to punish offenders to ensure that they recognize that what they have done is wrong, but also to protect others from crime. In contrast to other justifications of punishment grounded in deterrence, the duty view is developed in the light of a non-consequentialist moral theory: a theory which endorses constraints on the pursuit of the good. It is shown that it is normally wrong to harm a person as a means to pursue a greater good. However, there are exceptions to this principle in cases where the person harmed has an enforceable duty to pursue the good. The implications of this idea are explored both in the context of self-defense, and then in the context of punishment. Through the systematic exploration of the relationship between self-defense and punishment, the book makes significant progress in defending a plausible set of non-consequentialist moral principles that justify the punishment of wrongdoers, and marks a significant contribution to the philosophical literature on punishment. "A stimulating, original and well-written account that prompts a reconsideration of the existing foundation of punishment." --Legal Studies, Vol 32 No 3, 30/11/2012 "Tadros has put his agile, analytical mind to work to solve a problem that should be of central concern to all of us. And in that spirit, his work should be read and celebrated." --Kimberly Kessler Ferzan, Jotwell "If Tadros is right, philosophers of punishment must be moral and political philosophers too, and their philosophical horizons must expand accordingly. That it doubles as an attempt to meet this challenge makes The End of Harm an invigorating read." --James Edwards, Law Quarterly Review "In a nutshell, the duty view offers a deontological justification of punishment that is based on the deterrence effects of punishment, but avoids any commitment to the idea that proportionate punitive suffering is non-instrumentally valuable. This theoretical positioning is fascinating. It alone ensures that the duty view merits, and will receive, close scrutiny by theorists of punishment. Add to this the fact that Tadros' defense of his position is ingenious, draws on a wide range of philosophical resources, and manifests great sensitivity to moral nuance, and it becomes clear that the duty view is a powerful arrival among the justifications of punishment available today." --Kasper Lippert-Rasmussen, Criminal Law and Philosophy "I find a a great deal in [Tadros's] account of punishment to admire and even to borrow; this book is a magnificent contribution to criminal law theory. Tadros's arguments go directly to the heart of the deepest and most difficult questions about the normative foundations of the criminal law, serving as a painful reminder of the difficulty of constructing any rationale for our punitive practices. The Ends of Harm should induce all of us to rethink, refine, qualify, and even to abandon views that we have uncritically presupposed for a long time." --Douglas Husak, Law and Philosophy "Victor Tadros has produced a powerful and highly original moral justification for a practice of state punishment that would be more purposeful and humane than any presently existing system of criminal punishment. He argues with great cogency that the permissibility of punishment and the permissibility of self-defense have their common source in the enforcement of duties that wrongdoers owe to their victims. In the course of meticulously defending these comprehensive accounts of the right to punish and the right of self-defense, he illuminates a range of central issues in normative ethics, political philosophy, and legal theory. The Ends of Harm presents a profound and brilliant challenge both to our institutions of punishment and to our traditional ways of justifying them." --Jeff McMahan, Rutgers Univers
