An allocation rule is ‘consistent’ if the recommendation it makes for each problem ‘agrees’ with the recommendation it makes for each associated reduced problem, obtained by imagining some agents leaving with their assignments. Some authors have described the consistency principle as a ‘fairness principle’. Others have written that it is not about fairness, that it should be seen as an ‘operational principle’. We dispute the particular fairness interpretations that have been offered for consistency, but develop a different and important fairness (...) foundation for the principle, arguing that it can be seen as the result of adding ‘some’ efficiency to a ‘post-application’ and efficiency-free expression of solidarity in response to population changes. We also challenge the interpretations of consistency as an operational principle that have been given, and here identify a sense in which such an interpretation can be supported. We review and assess the other interpretations of the principle, as ‘robustness’, ‘coherence’ and ‘reinforcement’. (shrink)

Discussions of over 200 selected ethical problems that face the practicing physician on a daily basis. Alphabetical arrangement of problems, ranging from abortion to Zen. Entry includes lengthy discussion and references.

A mathematical model based upon catastrophe theory is derived to describe the kinematics of the wing beat in Dipteran flight. The parameters of the model correspond to anatomical and physiological characteristics of the insect.

We consider the problem of fair allocation in economies with indivisible goods. Our primary concept is that of an envy-free allocation, that is, an allocation such that no agent would prefer anyone else's bundle to his own. Since there typically is a large set (a continuum) of such allocations, the need arises to identify well-behaved selections from the no-envy solution. First we establish the non-existence of ‘population monotonic’ selections. Then we propose a variety of selections motivated by intuitive considerations of (...) fairness. (shrink)

James Frederick Ferrier was born in Edinburgh on June 16th, 1808. He was educated privately and at the Royal High School, Edinburgh. After spending two sessions at Edinburgh University, he entered Magdalen College, Oxford, where he graduated in 1831. Returning to Edinburgh, he qualified as an advocate in 1832, but devoted himself to philosophical studies, largely as a result of his close friendship with Sir William Hamilton. In 1838-9, he published An Introduction to the Philosophy of Consciousness in Blackwood's (...) Magazine. This was followed by a number of interesting articles and reviews, chiefly on sense-perception. In 1844, Ferrier deputised for SirWilliam Hamilton in the Chair of Logic and Metaphysics at Edinburgh, and, in the following year, he became Professor of Moral Philosophy and Politica Economy in St Andrews. In 1854, he published The Institutes of Metaphysics. He died in 1864, leaving behind him a valuable course of Lectures on Greek Philosophy, which was published posthumously. (shrink)

The famous ‘trolley problem’ began as a simple variation on an example given in passing by Philippa Foot , involving a runaway trolley that cannot be stopped but can be steered to a path of lesser harm. By switching from the perspective of the driver to that of a bystander, Judith Jarvis Thomson showed how the case raises difficulties for the normative theory Foot meant to be defending, and Thomson compounded the challenge with further variations that created still (...) more puzzles of broader interest. In recent years, her thought experiments have even been co-opted by psychologists engaged in the empirical study of moral judgment . Yet more than thirty years after launching the trolley problem, Thomson has now strikingly reversed course, retracting the very claim she had originally used to raise puzzles for Foot. I shall argue that this reversal is a mistake, leading to a needlessly counterintuitive, contrarian position about damage-control cases. Instead of overturning her earlier position, her new variations merely uncover a surprising insight about the conditions under which one may permissibly sacrifice another for a good end.1. The central case at issue is what Thomson now calls Bystander's Two Options: you are a bystander who sees a runaway trolley headed toward five innocent people who cannot move off the track; you cannot stop the trolley, but you have access to a switch that will divert it onto a side track where one innocent person is trapped. Is it permissible to throw the switch and divert the trolley toward lesser harm? The common answer, and Thomson's earlier one, is that it is: in cases like this, where there is a public threat and we can act on it so …. (shrink)

James Thomson envisaged a lamp which would be turned on for 1 minute, off for 1/2 minute, on for 1/4 minute, etc. ad infinitum. He asked whether the lamp would be on or off at the end of 2 minutes. Use of “internal set theory” (a version of nonstandard analysis), developed by Edward Nelson, shows Thomson's lamp is chimerical; its copy within set theory yields a contradiction. The demonstration extends to placing restrictions on other “infinite tasks” such as (...) Zeno's paradoxes of motion and Kant's First Antinomy. Resolution of such logical-philosophical problems leads to some very general constraints which must be placed upon the syntax of physical theories. In particular, at some scale space and time would appear granular. The suitability of internal set theory for analyzing phenomena is examined, using a paper by Alper and Bridger (1997) to frame the discussion. (shrink)

William of Malmesbury's Regesta Regum Anglorum is one of the great histories of England, and one of the most important historical works of the European Middle Ages. Although its focus is national, its scope encompasses most of Western Europe and beyond, providing a full-scale account of the First Crusade. Apart from its formidable learning, it is characterized by narrative skill and entertainment value - with topics including unpowered flight and Henry I's zoo.

The Doctrine of Double Effect (DDE) is an influential non-consequentialist principle positing a role for intention in affecting the moral permissibility of some actions. In particular, the DDE focuses on the intend/foresee distinction, the core claim being that it is sometimes permissible to bring about as a foreseen but unintended side-effect of one’s action some harm it would have been impermissible to aim at as a means or as an end, all else being equal. This article explores the meaning and (...) application of the DDE along with current debates over the nature of the intend/foresee distinction and its moral significance. How is the line between intended effects and merely foreseen but unintended side-effects to be drawn, and how are problem cases best handled? What is an appropriate methodology for debating the tenability of the DDE? How might the DDE interact with other non-consequentialist principles, and how might it be modified to capture other related factors (resulting perhaps in a Doctrine of Triple Effect) or to avoid certain problem cases? Does the DDE make permissibility turn on the actual intentions of particular agents, as critics such as Thomson and Scanlon assume, or is the role of intention more abstract? (shrink)

Most opposition to abortion stands or falls on whether a fetus is the sort of being whose life it is seriously wrong to end. In her influential paper ‘A defense of abortion,’ Judith Jarvis Thomson effectively sidesteps this issue, assuming the fetus is a person with the right to life yet arguing this alone does not give it the right to use the mother’s body. In a recent article, Perry Hendricks takes inspiration from Thomson and assumes the fetus (...) is not a person, arguing that abortion is wrong because causing fetal impairment is wrong and abortion is worse than causing fetal impairment. Here I argue Hendricks’ impairment argument fails. For Hendricks, risking fetal impairment is wrong because it risks harm to a future person, but if we assume the fetus is not a person, abortion doesn’t harm anyone, it merely prevents them from existing.

Don Marquis is well known for his future like ours theory, according to which the killing beings like us is seriously morally wrong because it deprives us of a future we can value. According to Marquis, human fetuses possess a future they can come to value, and thus according to FLO have a right to life. Recently Mark Brown has argued that even if FLO shows fetuses have a right to life, it fails to show that fetuses have a right (...) to use their mother's body, evoking Judith Jarvis Thomson's famous violinist case. In the wake of Brown's conclusion, Marquis presents a new argument—the parenthood argument —which he believes shows that abortion is seriously morally wrong. Here I argue that the PA fails to show abortion is seriously morally wrong for the same reasons FLO fails to show abortion is seriously morally wrong. (shrink)

Richard Cartwright's impact on other philosophers has been as much a product of his own personal contact with students and colleagues as the result of his written work. The essays in this book demonstrate the deep influence he has had, not only by his thinking but equally by his style and manner and, above all, by his clarity and purity of intention. All of the essays are concerned with the questions of logic, language, and metaphysics that have been at the (...) core of Cartwright's own work. The chapters and their authors are: The Consistency of Frege's Foundations of Arithmetic, George Boolos. Russell's "No-Classes" Theory of Classes, Leonard Linsky. Quine's Indeterminacy, Charles S. Chihara. Justifying Symbolizations, Harold Levin. Substitutivity, Scott Soames. Moore-Paradox, Sincerity Conditions, and Epistemic Qualification, Charles E. Caton. Matching Illocutionary Act Types, William P. Alston. Scattered Objects, Roderick M. Chisholm. Parts and Places, Helen Morris Cartwright. Ruminations on an Account of Personal Identity, Judith Jarvis Thomson. G_del's Ontological Proof, Jordan Howard Sobel. "The Concept of the Subject Contains the Concept of the Predicate," David Wiggins. Judith Jarvis Thomson is Professor of Philosophy at MIT. Philosophical Essays, the first collection of Richard Cartwright's work, is being published simultaneously by The MIT Press. (shrink)

In “Abortion and Ownership” John Martin Fischer argues that in Judith Jarvis Thomson’s violinist case you have a moral obligation not to unplug yourself from the violinist. Fischer comes to this conclusion by comparing the case with Joel Feinberg’s cabin case, in which he contends a stranger is justified in using your cabin to stay alive. I argue that the relevant difference between these cases is that while the stranger’s right to life trumps your right to property in the (...) cabin case, the violinist’s right to life does not trump your right to liberty in the violinist case.

In this paper, Leighton Thomson provides the reader with an overview of early 16th century English history and he explores the achievements and reversals of the period in terms of the epoch of discovery, the Renaissance humanists and the first stirrings of the Reformation. A contrast is drawn between Thomas More and his contemporary reformers, particularly William Tyndale and Martin Luther.

Kolak’s arguments for the thesis ‘there is only one person’ in fact show that the subject-in-itself is not a countable entity. The paper argues for this assertion by comparing Kolak’s concept of the subject with Kant’s notion of the transcendental unity of apperception (TUAP), which is a formal feature of experience and not countable. It also argues the point by contrasting both the subject and the TUAP with the notion of the individual human being or empirical self, which is the (...) main concern standard theories of personal identity such as those of Williams, Parfit and Nozick. Unlike the empirical self, but rather like Kant’s TUAP, the subject-in-itself cannot be counted because it is not an object or substance, despite Kolak’s thesis that there is only one. The paper also maintains that Kolak’s contention that the subject is an entity hinges on a strong and less plausible interpretation of Kant’s transcendental idealism. (shrink)

Hendricks set out to construct an antiabortion version of Jeff McMahan’s Embryo Rescue case in which you have two choices—(1) save a woman from an unwilling pregnancy or (2) save a fetus from being killed. In his Pregnancy Rescue case, he contends we ought to choose (2), which he thinks shows abortion is immoral. However, I argue the Pregnancy Rescue case is a false dilemma because you can save both. I propose an alternative, more elegant dilemma, the Ectogenesis Rescue case (...) with the same choices (1) and (2). Hendricks also believes his case can serve as an antiabortion version of Thomson’s Violinist case, showing that abortion is immoral even if a fetus is not a person. However, while Thomson’s Violinist substitutes the fetus with a person, Hendricks fails to substitute the fetus with something that is not a person. I propose an alternative, the Snakebite Rescue case, which does this. (shrink)

Many people believe the morality of abortion stands or falls on the moral status of the fetus, with abortion opponents arguing fetuses are persons with a right to life. Judith Jarvis Thomson bypasses this debate, arguing that even if we assume fetuses have a right to life, this is not a right to use other people’s bodies. Recently Perry Hendricks attempts to bypass discussion of rights, assuming that if he can show that some people have a right to use (...) other’s bodies, then we ought to restrict abortion (and perhaps compel organ donation, charity, etc.). Hendricks attempts to illustrate this by way of a Feinberg-style cabin case. I argue Hendricks’ restrictivist argument fails. (shrink)

Michal Pruski and Richard C. Playford argue that if partial ectogenesis technology becomes available then it would undermine Judith Jarvis Thomson’s defense of abortion. Thomson argues that even if a fetus has a right to life, this is not a positive right to be given whatever one needs to survive; it is not a right to use the mother’s body or to risk her life without her permission. Pruski and Playford argue that when the risks involved in ectogenesis (...) are comparable to those of abortion, then minimal decency requires gestational mothers to opt for ectogenesis over abortion. This argument hinges on egregious misunderstandings of (1) ectogenesis technology, (2) medical and surgical abortion, and (3) medical consent. (shrink)

In his recent article “Even if the fetus is not a person, abortion is immoral: The Impairment Argument,” Perry Hendricks sets out to sidestep thorny metaphysical questions regarding human fetuses and present a new argument against abortion – if impairing a fetus with fetal alcohol syndrome is immoral, then killing the fetus is immoral. Hendricks takes inspiration from Judith Jarvis Thomson’s defense of abortion – that even if fetuses are persons with a right to life, the right to life (...) is not the right to use others, so it is acceptable to induce abortion. Together with Bruce Blackshaw, Hendricks set out to strengthen the impairment argument by appealing to Don Marquis’s future like ours (FLO) account of the wrongness of killing. Here I argue the impairment argument falls short in three ways. First, Hendricks and Blackshaw fail to assume fetuses aren’t persons, broadly construed. Second, they fail to show that impairing a fetus is immoral. Third, they overlook abortions that (merely) let the fetus die. Finally, I argue Thomson’s defense of abortion preempts the significance of the impairment argument; Thomson seems to show that even if killing a fetus is prima facie immoral, women still have the right to induce abortion.

This article defends the project of giving a single pleasure-based account of goodness against what may seem a powerful challenge. Aristotle, Peter Geach and Judith Thomson have argued that there is no such thing as simply being good; there is only (for example) being a good knife or a good painting (Geach), being serene or good to eat (Thomson), or being good in essence or in qualities (Aristotle). But I argue that these philosophersgoodgoodknife’.

For, I argue, hedonistic accounts of goodness tend to imply that the unqualified term ‘good’ has little or no application to the things we talk about; while if we qualify hedonic goodness in certain ways, we generate usable predicates that match the varieties of goodness recognized by the three philosophers. And those qualifications happen to be natural interpretations of signals we do use alongside ‘good’, such as ‘knife’. (shrink)
