I start from the presupposition that the use of force against another is justified only in self-defence or in defence of others against aggression. If so, the main work of justifying punishment must rely on its deterrent effect, since most punishments have no other significant self-defensive effect. It has often been objected to the deterrent justification of punishment that it commits us to using offenders unacceptably, and that it is unable to deliver acceptable limits on punishment. I describe a sort (...) of deterrent theory which can avoid both of these objections. (shrink)

The slogan that criminal liability requires an ‘act’, or a ‘voluntary act’, is still something of a commonplace in textbooks of criminal law. There are, it is usually added, certain exceptions to this requirement— cases in which liability is in fact, and perhaps even properly, imposed in the absence of such an act: but the ‘act requirement’ is taken to represent a normally minimal necessary condition of criminal liability. Even offences of strict liability, for which no mens rea is required, (...) require an act: thus to the familiar slogan that actus non facit reum nisi metis sit rea we can add the prior, more fundamental slogan that mens non facit reum nisi actus sit reus ; before we ask whether a defendant acted with mens rea or fault, we must ask whether he committed a criminal act at all.

Intention is at the heart of criminal law. If it is not the mens rea requirement found most often in offences, it is still the standard against which other grades of fault tend relatively to be judged. It has generated much controversy, as the crucial question, “Did the defendant intend X?” is resistant to clear answers. This paper argues that intention-questions are difficult because intention is not the thing law takes it to be: Importantly, contrary to law's assumptions, it is (...) neither a state of mind nor is it connected in an exclusive manner to the reasons for which we act.

Anglo-American criminal law traditionally demands a criminal purpose for an attempt conviction, even when the crime attempted requires only foresight or recklessness. Some legal philosophers have defended this rule by appeal to an alleged difference in the moral character or intentional structure of intended versus non-intended harms. I argue that there are reasons to be skeptical of any such differences; and that even if conceded, it is only on the basis of an unworkable view of criminal responsibility that such a (...) distinction would support a rule restricting attempts to criminal purpose. I defend instead the continuity thesis, according to which attempts are functionally continuous with endangerment offenses: both are legal efforts to regulate unreasonably dangerous conduct. The upshot of the continuity thesis is that there is little substantive difference between attempt and endangerment in principle, no matter how they are labeled in law. (shrink)

This essay defends the asymmetry between the badness of spontaneous and induced abortions in order to explain why anti-abortionists prioritize stopping induced abortions over preventing spontaneous abortions. Specifically, it argues (1) the distinction between killing and letting-die is of more limited use in explaining the asymmetry than has sometimes been presumed, and (2) that accounting for intentions in moral agency does not render performances morally inert. Instead, anti-abortionists adopt a pluralist, nonreductive account of moral analysis which is situated against a (...) backdrop that sees the limits of our ability to control the process of fertility as themselves valuable. Although this view is complex, the paper concludes by arguing that it has the advantage of explaining features of the anti-abortion outlook that have sometimes been overlooked. First, it accounts for why the pre-Roe regime of abortion restrictions primarily imposed penalties on doctors who induced abortions rather than the women who seek them. Second, it explains why the advent of ectogestation will not prompt anti-abortionists to compromise on ‘disconnect abortions,’ which putatively let the embryo die by extracting it from the mother’s womb.

Although widely used across psychology, economics, and philosophy, the concept ofeffort is rarely ever defined. This article argues that the time is ripe to look for anexplicit general definition of effort, makes some proposals about how to arrive at thisdefinition, and suggests that a force-based approach is the most promising. Section 1presents an interdisciplinary overview of some chief research axes on effort, and arguesthat few, if any, general definitions have been proposed so far. Section 2 argues thatsuch a definition is (...) now needed and proposes a basic methodology to arrive at it, whosefirst step is to make explicit the various tacit assumptions about effort made acrosssciences and ordinary thinking. Section 3 unearths 4 different conceptions of effortfrom research on effort so far:primitive-feelings accounts,comparator-based accounts,resource-based accountsandforce-based accounts. It is then argued that the first 2kinds of accounts, although interesting in their own right, are not strictly speaking abouteffort. Section 4 considers the 2 most promising general approaches to efforts: re-source-based and force-based accounts. It argues that these accounts are not only compatible but actually extensionally equivalent. This notwithstanding, it explains why force-based accounts should be regarded as more fundamental than resource-basedaccounts -/- . (shrink)
