“Tell me," Wittgenstein once asked a friend, "why do people always say, it was natural for man to assume that the sun went round the earth rather than that the earth was rotating?" His friend replied, "Well, obviously because it just looks as though the Sun is going round the Earth." Wittgenstein replied, "Well, what would it have looked like if it had looked as though the Earth was rotating?” What would it have looked like if we looked at all (...) sciences from the viewpoint of Wittgenstein’s philosophy? Wittgenstein is undoubtedly one of the most influential philosophers of the twentieth century. His complex body of work has been analysed by numerous scholars, from mathematicians and physicists, to philosophers, linguists, and beyond. This volume brings together some of his central perspectives as applied to the modern sciences and studies the influence they may have on the thought processes underlying science and on the world view it engenders. The contributions stem from leading scholars in philosophy, mathematics, physics, economics, psychology and human sciences; all of them have written in an accessible style that demands little specialist knowledge, whilst clearly portraying and discussing the deep issues at hand.

Autonomous and automatic weapons would be fire and forget: you activate them, and they decide who, when and how to kill; or they kill at a later time a target you’ve selected earlier. Some argue that this sort of killing is always wrong. If killing is to be done, it should be done only under direct human control. (E.g., Mary Ellen O’Connell, Peter Asaro, Christof Heyns.) I argue that there are surprisingly many kinds of situation where this is false and (...) where the use of Automated Weapons Systems would in fact be morally required. These include cases where a) once one has activated a weapon expected then to behave lethally, it would be appropriate to let it continue because this is part of a plan whose goodness one was best positioned to evaluate before activating the weapon; b) one expects better long-term consequences from allowing it to continue; c) allowing it to continue would express a decision you made to be resolute, a decision that could not have advantaged you had it not been true that you would carry through with it; d) the weapon is mechanically not recallable, so that, to not allow it to carry through, you would have had to refrain from activating it in the first place, something you expected would have disastrous consequences; e) you must deputize necessary killings to autonomous machines in order to protect yourself from guilt you shouldn’t have to bear; f) it would be morally better for the burden of responsibility for the killing to be shared among several agents, and the agents deputizing killing to machines can do this, especially where it’s not predictable which machine will be successful; g) a killing would be morally better done with elements of randomness and lack of deliberation, and a (relatively stupid) machine could do this where a person could not; h) the machine would be acting as a Doomsday Device, so that it could not have had its hoped for deterrent effect had you not ensured that you would be unable to recall it if enemy action activated it; i) letting it carry through is a necessary part of its own learning process, and you expect that this learning will have salutary effects later on; j) human intervention in the machine’s operation would disastrously impair its precision, or its speed and efficiency; k) using non-automated methods would require human resources you just don’t have in a task that nevertheless must be done (e.g., using land-mines to protect remote installations); l) the weapon has such horrible and indiscriminate power that it is doubtful whether it could be actually used in ways compatible with International Humanitarian Law and the Laws of War, which require that weapons be used only in ways respecting distinctness, necessity and proportionality, but its threat of use could respect these principles in affording deterrence provided human error cannot lead to their accidental deployment, this requiring that they be controlled by carefully designed autonomous and automatic systems. I then consider objections based on conceptions of human dignity and find that very often dignity too is best served by autonomous machine killing. Examples include saving your village by activating a robot to kill invading enemies who would inflict great indignity on your village, using a suicide robot to save yourself from a less dignified death at enemy hands, using a robotic drone to kill someone otherwise not accessible in order to restore dignity to someone this person killed and to his family, and using a robot to kill someone who needs killing, but the killing of whom by a human executioner would soil the executioner’s dignity. I conclude that what matters in rightful killing isn’t necessarily that it be under the direct control of a human, but that it be under the control of morality; and that could sometimes require use of an autonomous or automated device. (This paper was formerly called "Fire and Forget: A Defense of the Use of Autonomous Weapons in War" on Philpapers; the current title is the title of the published version.). (shrink)

Ideal rule utilitarianism says that a moral code C is correct if its acceptance maximizes utility; and that right action is compliance with C. But what if we cannot accept C? Rawls and L. Whitt suggest that C is correct if accepting C maximizes among codes we can accept; and that right action is compliance with C. But what if merely reinforcing a code we can't accept would maximize? G. Trianosky suggests that C is correct if reinforcing it maximizes; and (...) that right action is action that has the effect of reinforcing compliance with C. I object to this and argue that C is correct if both accepting and reinforcing C would maximize and if C is reinforcible; and that right action consists in coming as close as possible to perfect acceptance of and compliance with C.

For scholars of American philosophy, this anthology of essays on S. C. Pepper's works on metaphysics, aesthetics, and value theory is especially a welcome one. Also included is a reprint of a little known but valuable essay by Pepper entitled "Metaphor in Philosophy," which originally appeared in volume 3 of Phillip S. Wiener's Dictionary of the History of Ideas. In this essay, Pepper discusses his root metaphor theory in relation to Bacon and Kant, and some contemporary uses of the notion (...) of paradigm, e.g., Wittgenstein and Kuhn. Lewis E. Hahn's "The Stephen C. Pepper Papers, 1903-1972" gives an informative account of six book-length unpublished manuscripts in the Pepper Archives at the Southern Illinois University. The rest of the essays concentrate on the various aspects of Pepper's works. A few deal with aesthetic theory and its application to critical practice. Of philosophical interests are papers by Elmer H. Duncan, David B. Richardson, Robert J. Yanal, Robert L. Armstrong, and Brian Caraher, and a short essay by Charles Hartshorne and a response by Joseph H. Monast. Duncan gives a just but critical account of the neglect of Pepper's Sources of Value, and a highly appreciative appraisal of Pepper's World Hypotheses. Caraher's careful essay on the conflicting root metaphors in Frege's theory of meaning offers interesting application of Pepper's conception of formism and contextualism to problems in Frege's philosophy. A variety of problems such as the root metaphor theory, descriptive definition and aesthetic experience are discussed. Efron's long introductory essay entitled "Pepper's Continuing Value" serves its purpose well in terms of indicating Pepper's influence in non-philosophical disciplines and the problems that arise in Pepper's value theory. What is missed is a sustained critical examination of Pepper's root metaphor theory, characterization of the various world hypotheses including Pepper's own selectivism, and its relation to ethical theory. The anthology however is useful in indicating the scope of Pepper's influence and the need to examine his contributions with reference to contemporary philosophical problems.--A.S.C. (shrink)

Dr. Leaf's article in the Journal of Hellenic Studies has recalled our attention to the venerable problem of the Rhesus. I hasten to give my adhesion to his main contention that the play is a pièce d'occasion justifying or sanctifying the foundation of the city of Amphipolis. But, as he remarks, seeing that the oracle ordering the removal of the bones of Theseus from Skyros to Athens preceded the actual removal by some years, so this play may be intended to (...) prepare for the actual removal of the bones of Rhesus from Troy by Hagnon, and may be prior to it by several years. For this official theft—doubtless arranged beforehand—we have only the authority of Polyainos' Strategemata, but it is a story which seems likely in itself, and goes far to explain the previously obscure lament of the Muse at the end of the play. My object is to examine the play afresh and see whether anything prevents our believing that it was written and exhibited somewhere near 440 B.C., in which case of course it is almost certainly the work of Euripides and not far from his Cyclops in date.

This is a major contribution to post-Keynesian thought. With studies of the key pioneers - Keynes himself, Kalecki, Kahn, Goodwin, Kaldor, Joan Robinson, Sraffa and Pasinetti - G. C. Harcourt emphasizes their positive contributions to theories of distribution, pricing, accumulation, endogenous money and growth. The propositions of earlier chapters are brought together in an integrated narrative and interpretation of the major episodes in advanced capitalist economics in the post-war period, leading to a discussion of the relevance of post-Keynesian ideas to (...) both our understanding of economics and to policy-making. The appendices include biographical sketches of the pioneers and analysis of the conceptual core of their discontent with orthodox theories. Drawing on the author's experience of teaching and researching over fifty years, this book will appeal to undergraduate and graduate students interested in alternative approaches to theoretical, applied and policy issues in economics, as well as to teachers and researchers in economics.

George Bowles and Thomas Gilbert claim that illatives such as so, therefore, and hence convey the meaning that the premise confers upon the conclusion a probability greater than 1/2. This claim is false, for there are straightforward uses of these illatives that do not convey the meaning that the probability is greater than 1/2. In addition, because Bowles' and Gilbert's claim is false, a revision of their definition of argument is required.

It is hardly necessary to recapitulate Rhys Roberts' cumulative and convincing proof that the treatise ‘On the Sublime’ was not written by Cassius Longinus, the tutor of Zenobia, but belongs to the early days of the Empire. Not the least convincing of the arguments for this date is the fact that the treatise is suggested by and put out as a substitute for the Περ ״ϒψоνς of Caecilius of Calacte, who according to Suidas taught rhetoric in Rome in the time (...) of Augustus. Now Caecilius was an intimate friend of Dionysius of Halicarnassus : they were both Atticists and fellow-workers in leading literary Romans back to the best models of Greek prose style. But Dionysius is no candidate for the authorship of the extant treatise, which is not one that he could have written. On the other hand he gives a plain indication by which to identify its writer, which Rhys Roberts mentioned but did not adopt. It is the object of this paper to put this identification seriously forward. (shrink)

This paper and its predecessor () are about the question: 'Are the events in the entire universe encoded in and predictable from any of its parts?' To approach a positive answer in classical physics, the following result is proved and commented on: in Newton's theory of gravitation, the entire trajectory of a particle can be predicted given any segment of it, regardless of how the other particles are moving-provided that there is only a finite number of particles and that their (...) speeds remain bounded. (It is this condition, together with a set of parameters characterising the motion of the other particles, which enables us to estimate the effect of the other particles on the trajectory of the given particle.) The extension of this result to other theories, in particular to special relativity, is discussed. (shrink)

Many defenders of the possibility of time travel into the past also hold that such time travel places no restrictions on what said time travelers can do. Some hold that it places at least a few restrictions on what time travelers can do. In attempting to resolve this dispute, I reached a contrary conclusion. Time travelers to the past cannot do other than what they in fact do. Using a very weak notion of can, I shall argue that the correspondingly (...) strong cannot do otherwise applies in the case of backwards time travel. I defend this result from objections. (shrink)
