In 1884 Sir William Thomson (later Lord Kelvin) delivered a significant series of lectures on physics at the Johns Hopkins University in Baltimore. This book presents the twenty lectures in their original form for the first time.

William Thomson, later Lord Kelvin, played a major role in the nineteenth century in changing scientific theory from the statical view, associated with imponderables, to the dynamical view which conceived of energy as a separate and convertible entity. Thomson's conversion from the statical to the dynamical view of nature was due to the influence of experimentalists, Michael Faraday and James Prescott Joule. It was Thomson's use of mathematical metaphor that enabled him to interpret on a theoretical (...) level the physical explanation given by Faraday and Joule. (shrink)

Thomson, Kelvin You might be surprised to learn that China, home of the much derided one-child policy, has a higher birth rate than Italy, home of the Vatican. This suggests Chinese families are quietly defying their political leaders and Italian families are quietly defying their religious ones. But the overall global picture is one of rapid population growth.

G. G. Stokes and Lord Kelvin helped bring about conceptual and institutional changes that transformed the science of physics. Indeed, they and their Victorian colleagues constituted one of the most significant groups of scientists in the whole history of science. This collection of letters was first published in 1990, and provides, therefore, invaluable insight and information for a period of major historical importance. Stokes and Kelvin corresponded for over fifty years as professors in Cambridge and Glasgow, respectively, thus amassing what (...) is easily the largest extant correspondence between two Victorian physicists. The letters range widely over the people, ideas, and institutions of the age. They illuminate the histories of Cambridge and Glasgow Universities and the Royal Society of London, for example, as well as developments in electromagnetism, hydrodynamics, elasticity, optics, and X-rays. The editor's introduction describes the context of the pair's careers, while guiding the reader into their correspondence. (shrink)

Based largely on unpublished manuscript material from the Kelvin papers, and especially on a series of letters exchanged in 1867 between Fleeming Jenkin and William Thomson , this paper aims to examine the background and content of the Thomson-Jenkin speculations on the nature of matter. The letters formed an interlude in a long collaboration over electrical patents and raise the fundamental question of whether these speculations, involving the construction of a variety of conceptual models, derive primarily from (...) older traditions of speculative matter theory, or from contemporary problems within natural philosophy qua physics. The correspondence also provided the immediate background to Jenkin's North British review article of 1868 on ‘Lucretius and the atomic theory’. (shrink)

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)

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.

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)
