In the Principles of the Penal Code, Jeremy Bentham described offences that he labelled presumed or evidentiary. The conduct penalized under such offences is punished not because it is intrinsically wrong, but because it probabilistically indicates the presence of an intrinsic wrong. Bentham was sceptical of the need to create offences, but grudgingly accepted their value in light of deficiencies in procedure and the judiciary. These days the scepticism is even greater, with courts and commentators in the United States, Canada, the United Kingdom and elsewhere believing that such ‘proxy’ offences deny a defendant the right to establish that he did not engage in the conduct that the presumed offence probabilistically but not necessarily indicates. On closer analysis, however, such scepticism appears unjustified. Almost all offences, and indeed almost all legal rules, are premised on a probabilistic relationship between the behaviour the rule encompasses and the behaviour that is the rule-maker's real concern. Presumed offences may make this relationship especially obvious, but it is a relationship that exists whenever the law operates by the use of rules.

Despite the enormous impact that war and the threat of war have had on human well-being, utilitarians have had surprisingly little to say about when, if ever, we may fight wars. Discussion of this question has been dominated by realism, pacifism and just war theory. This article takes some preliminary steps toward remedying this situation. I begin by spelling out what I call the Utilitarian War Principle (UWP). After presenting some considerations in its favour and answering some possible objections to it, I compare UWP with pacifism and with the principles of jus ad bellum found in the work of contemporary just war theorists. I argue that adherents of UWP should treat those principles as secondary moral principles, which, although subordinate to UWP, can and should guide its application and which, in turn, should be refined and revised with this goal in mind.

What difference does it make to matters of value, for a desire-satisfactionist, if a given desire is absent, rather than present? I argue that it is most plausible to hold that the state in which a given desire is satisfied is, other things being equal, incommensurate with the state in which that desire does not exist at all. In addition to illustrating the internal attractions of the view, I demonstrate that this idea has attractive implications for population ethics. Finally, I show that the view is not subject to John Broome's ‘greedy neutrality’ worry.

I argue that Mill introduced the distinction between quality and quantity of pleasures in order to fend off the then common charge that utilitarianism is ‘a philosophy for swine’ and to accommodate the (still) widespread intuition that the life of a human is better, in the sense of being intrinsically more valuable, than the life of an animal. I argue that in this he fails because in order to do successfully he would have to show not only that the life of a human is preferable to that of an animal on hedonistic grounds, but also that it is in some sense nobler or more dignified to be a human, which he cannot do without tacitly presupposing non-hedonistic standards of what it means to lead a good life.

David Enoch recently defended the idea that there are valid inferences of the form ‘it would be good if p, therefore, p’. I argue that Enoch's proposal allows us to infer the absurd conclusion that ours is the best of all possible worlds.

In ‘Autonomy and Adaptive Preferences’, Ben Colburn claims that preferences formed through covert influences are defective. I show that Colburn's argument fails to establish that anything is wrong with preferences formed in this manner.
