Abstract

Bentham’s An Introduction to the Principles of Morals and Legislation (IPML) was originally intended to introduce a utilitarian penal code. Such a code would apply the principle of utility to the task of designing a system of criminal law. Part I, Section I of this two-part paper gives an overview of IPML, in which the basic moral assumptions of utilitarianism are presented, and the central concept of mischief is emphasised. The principle of utility favors making into criminal offences actions that are mischievous and profitable to punish. Section II discusses Chapter XVI of IPML. This chapter is a taxonomy of possible offences and the penal code would explain which acts in the taxonomy are mischievous and profitable to punish. This chapter also suggests how Bentham was beginning to see the need for other utilitarian legal codes. Section III discusses Bentham’s concept of a ‘catechism of reasons’ to be included in the code, which would explain to the citizenry why each action in the code is mischievous. Section IV discusses two important sets of manuscripts that illustrate the reasoning that was to accompany the code. The first briefly treats the offence of cruelty to animals and expands on the thinking in the famous footnote to Chapter XVII that argues that non-human animals can be treated wrongly, while the second examines the remarkable treatment of ‘paederasty’, that is, consensual sex between adult males. IPML does not mention paederasty, although several passages are relevant to it. These passages suggest that paederasty is not mischievous. The manuscripts expand on these suggestions, and explicitly argue that paederasty ought not to be an offence. Several new issues are discussed, such as the effect of paederasty on population size. In the subsequent Part II of this paper, Bentham’s treatment of punishment in IPML, The Rationale of Punishment, and the penal code will be discussed.
