Contractualism and Punishment

Abstract

T. M. Scanlon's contractualism is a meta-ethical theory that explains moral motivation and also provides a conception of how to carry out moral deliberation. It supports non-consequentialism––the theory that both consequences and deontological considerations are morally significant in moral deliberation. Regarding the issue of punishment, non-consequentialism allows us to take account of the need for deterrence as well as principles of fairness, justice, and even desert. Moreover, Scanlonian contractualism accounts for permissibility in terms of justifiability: an act is permissible if and only if it can be justified to everyone affected by it. This contractualist thesis explains why it is always impermissible to frame an innocent person, why vicarious punishment is impermissible, and why there has to be a cap on sentences. Contractualism therefore allows us to take deterrence as a goal of punishment without the excess of utilitarianism. This paper further argues that the resulting view is superior to pure retributivism. Finally, it shows why legal excuses and mitigation can be justified in terms of the notion of negative desert.
