The philosophical zombie is an imaginary being that is just like us in every way, except that philosophical zombies don't have experience. Elite athletes who are 'in the zone' also lack experience, therefore, while in a zone state they are similar to philosophical zombies.

© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

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)

In Religious Studies xxvi Harold W. Noonan and Charles B. Daniels severally take issue with my ‘Reincarnation and Relativized Identity’. Both make valuable points but both, I think, have somewhat missed the point of my original article. In that paper I singled out five different views on the possibility of life after death: that we are reincarnated in the self-same body we had in our pre-mortem state; that we are reincarnated in another — in a different — body; that we (...) continue to exist in a disembodied form, which may or may not culminate in re-embodiment; that pre-mortem life is a dream from which postmortem life is the awakening; that none of the above holds: there is no life after death.

This chapter conceptually analyzes the post-traumatic stress injuries called moral injury, moral fatigue or exhaustion, and broken spirit. It then identifies two puzzles. First, soldiers sometimes sustain moral injury even from doing right actions. Second, they experience moral exhaustion from making decisions even where the morally right choice is so obvious that it shouldn’t be stressful to make it; and even where rightness of decision is so murky that no decision could be morally faulted. The injuries result of mistaken moral (...) self-evaluation. Methods of preventing and treating these injuries are defended, including training in self-forgiveness, moral off-loading of actions and decisions to persons and devices less likely to feel inappropriate guilt, and the use of drugs to prevent such guilt. The foregoing has been about moral injury erroneously resulting from the non-violation of a correct moral code. But the chapter then introduces the concept of moral pseudo-injury—felt moral injury that has in reality resulted from violation of a false moral code, so that no one has really been morally injured. This can be used as a method in warfighting. And since the injuries it produces are illusory, this would be morally superior to physical violence. For it causes less injury to its victims, and should cause less guilt in those who must inflict it. Historical precedents are considered. Finally, our enemies often use moral pseudo-injury against us, in the form of terrorist violence against civilians. Terrorism causes comparatively few harms, yet we mistakenly see it as more morally horrific than conventional combat that causes much worse loss of life among armed forces members. Here we need the nuancing and clarifying power of philosophy to restore a sense of proportion, thence to prevent or therapize the moral pseudo-injury we may experience from these sorts of attacks. (This is a pre-penultimate version of the published version, available from OUP at the external link, which contains minor variances. The paper was earlier known as "PTSD Weaponized: A Theory of Moral Injury"; that now superseded version is archived under "past conferences" on the Center for Ethics and the Rule of Law website.).

This chapter discusses the fundamental question of the defense industry’s role and legitimacy for societies. It begins with a parable of a psychopath doing something self-serving that has beneficial moral consequences. Analogously, it is argued, the defense industry profiting by selling weapons that can kill people makes it useful in solving moral problems not solvable by people with ordinary moral scruples. Next, the chapter argues that while the defense industry is a business, it is also implicated in the security of (...) its home nations. In addition, its products can be used for good or evil. Thus, it must navigate conflicting values, with the result that the rules often thought to rightly regulate the industry—codes of business ethics, engineering ethics, procurement ethics, plus laws of the land, and dicta of conscience—need supplementing by general moral reflection. This chapter argues for a principle that tells how to decide when to violate the rules, for a theory of rational choice on which choosing by this principle is rational, and for teaching that theory to defense industry employees to ensure their ethical behavior.

This book provides a thought-provoking analysis of the role of metaphysics within the Christian theological tradition. Douglas Clyde Macintosh argues that the tendency to prioritize abstract, speculative thinking over more concrete, practical concerns has been a major contributing factor to the decline of religious faith in the modern era. He proposes a return to a more grounded, experiential approach to theology, one that emphasizes the importance of community, tradition, and ethical action. A timely and compelling call to reconsider the (...) foundations of Christian thought and practice.

While Autonomous Weapons Systems have obvious military advantages, there are prima facie moral objections to using them. By way of general reply to these objections, I point out similarities between the structure of law and morality on the one hand and of automata on the other. I argue that these, plus the fact that automata can be designed to lack the biases and other failings of humans, require us to automate the formulation, administration, and enforcement of law as much as (...) possible, including the elements of law and morality that are operated by combatants in war. I suggest that, ethically speaking, deploying a legally competent robot in some legally regulated realm is not much different from deploying a more or less well-armed, vulnerable, obedient, or morally discerning soldier or general into battle, a police officer onto patrol, or a lawyer or judge into a trial. All feature automaticity in the sense of deputation to an agent we do not then directly control. Such relations are well understood and well-regulated in morality and law; so there is not much challenging philosophically in having robots be some of these agents — excepting the implications of the limits of robot technology at a given time for responsible deputation. I then consider this proposal in light of the differences between two conceptions of law. These are distinguished by whether each conception sees law as unambiguous rules inherently uncontroversial in each application; and I consider the prospects for robotizing law on each. Likewise for the prospects of robotizing moral theorizing and moral decision-making. Finally I identify certain elements of law and morality, noted by the philosopher Immanuel Kant, which robots can participate in only upon being able to set ends and emotionally invest in their attainment. One conclusion is that while affectless autonomous devices might be fit to rule us, they would not be fit to vote with us. For voting is a process for summing felt preferences, and affectless devices would have none to weigh into the sum. Since they don't care which outcomes obtain, they don't get to vote on which ones to bring about. (shrink)

While agreeing with his conclusion , I disagree at almost every step with his method of arriving at it.

This article focuses on the effectiveness of antihomophobia discourses and explores the process of teaching and learning about heteronormativity. The author offers an interrogation of the regulatory fictions within heteronormativity and frameworks of resistance and examines attempts to move beyond established views of sexual minority students and explore the ways in which queer research has, and continues to, bring a counternarrative to staid liberal notions of reform and the well-intentioned rhetoric of diversity and difference. This analysis raises critical questions about (...) the possibility of moving beyond standard antihomophobia curricula and questions approaches such as the one-off lecture format and other condensed discussions of heteronormativity and homophobia.

The indexical thesis says that the indexical terms, “I”, “here” and “now” necessarily refer to the person, place and time of utterance, respectively, with the result that the sentence, “I am here now” cannot express a false proposition. Gerald Vision offers supposed counter-examples: he says, “I am here now”, while pointing to the wrong place on a map; or he says it in a note he puts in the kitchen for his wife so she’ll know he’s home even though he’s (...) gone upstairs for a nap, but then he leaves the house, forgetting to remove the note. The first sentence is false by virtue of “here” not necessarily referring to the place of utterance, the second sentence, by virtue of “now” not necessarily referring to the time of utterance. We argue that these sentences express falsehoods only because the terms are being used demonstratively, not indexically – the distinction pertains not to words simpliciter, but to uses of words. When used indexically, the terms refer in accord with the indexical thesis; but when used demonstratively, their referents depend on how devices of ostension are used with their utterance – pointings, and the like. Thus Vision’s first sentence really says, “I am there now”, referring to the place on the map the finger is pointing to. As for his second sentence, we distinguish the time of utterance or production of a sentence from the time of its uptake. Due to the pragmatics of interpretation, the sentence really says “I” – the person ‘uttering’ the note – “am here” – here where the note is, with the note serving as a kind of proxy ‘finger’ – “now” – where “now” refers to the time of uptake of the note, i.e., when it is read. “I” refers indexically, “here”, demonstratively, and “now”, indexically, but indexically to the time of uptake. Since the sentence is not purely indexical, its falsehood doesn’t threaten the indexical thesis. A similar treatment is given of teletyped messages about the typer’s location. (shrink)

Theories of practical rationality say when it is rational to form and fulfill intentions to do actions. David Gauthier says the correct theory would be the one our obeying would best advance the aim of rationality, something Humeans take to be the satisfaction of one’s desires. I use this test to evaluate the received theory and Gauthier’s 1984 and 1994 theories. I find problems with the theories and then offer a theory superior by Gauthier’s test and immune to the problems. (...) On this theory, it is rational to treat something different as the aim when doing so would advance the original aim. I argue that the idea that this would be irrational bad faith entails contradictions and so is false, as must be theories saying that rationally we must always treat as the aim the bringing about of objectively good states of affairs or obeying a universalizable moral code.

The New Evil Demon problem has been hotly debated since the case was introduced in the early 1980’s (e.g. Lehrer and Cohen 1983; Cohen 1984), and there seems to be recent increased interest in the topic. In a forthcoming collection of papers on the New Evil Demon problem (Dutant and Dorsch, forthcoming), at least two of the papers, both by prominent epistemologists, attempt to resist the problem by appealing to the distinction between justification and excuses. My primary aim here is (...) to critically evaluate this new excuse maneuver as a response to the New Evil Demon problem. -/- Their response attempts to give us reason to reject the idea that victims of the New Evil Demon have justification for believing as they do. I shall argue that this approach is ultimately unsuccessful, however much of value can be learned from these attempts. In particular, progress in the debate can be made by following those who advance the excuse maneuver and make explicit the connection between epistemic justification and epistemic norms. By doing so, the questions being debated are clarified, as is the methodology being used to attempt to answer them. (shrink)

For the tradition, an action is rational if maximizing; for Gauthier, if expressive of a disposition it maximized to adopt; for me, if maximizing on rational preferences, ones whose possession maximizes given one's prior preferences. Decision and Game Theory and their recommendations for choice need revamping to reflect this new standard for the rationality of preferences and choices. It would not be rational when facing a Prisoner's Dilemma to adopt or co-operate from Amartya Sen's "Assurance Game" or "Other Regarding" preferences. (...) But there are preferences which it maximizes to adopt and co-operate from. (shrink)

The move towards the use of new technologies and the new focus on citizen engagement in Scotland provides the opportunity for e-democracy to emerge. Working towards the goal of e-democracy, the International Teledemocracy Centre is developing a body of ICT, supporting skills, tools and techniques, designed specifically to facilitate the use of technology, capable of enhancing democratic engagement. This paper begins to articulate how citizens are engaging with government and with their elected representatives about issues that concern them, using technology (...) specially designed for the purpose. The paper examines the nature of e-democracy and considers concepts of democracy, issues of democratization, and issues surrounding citizen access and participation. In addition, the paper discusses the design and use of two electronic tools developed by the ITC between 1999 and 2001 i. e. e-consultant and e-petitioner. Finally, the paper presents analyses of findings drawn from research to monitor and evaluate the use of these tools and the arrangements which accompany their entry into society. (shrink)

There are various equivalent formulations of the Church-Turing thesis. A common one is that every effective computation can be carried out by a Turing machine. The Church-Turing thesis is often misunderstood, particularly in recent writing in the philosophy of mind.

David Gauthier suggested that all genuine moral problems are Prisoners Dilemmas (PDs), and that the morally and rationally required solution to a PD is to co-operate. I say there are four other forms of moral problem, each a different way of agents failing to be in PDs because of the agents’ preferences. This occurs when agents have preferences that are malevolent, self-enslaving, stingy, or bullying. I then analyze preferences as reasons for action, claiming that this means they must not target (...) the impossible, they must be able to be acted on in the circumstances, their targets must be attainable, and having the preferences must make their targets more likely. For groups of agents to have a distribution of preferences, their preferences must jointly have those four features, this imposing a kind of universalizability requirement on possible preferences. I then claim that, if all agents began with preferences satisfying these requirements, their preferences would not be of the morally problematic sort (on pain, variously, of circularity or contradiction in the specification of their targets). Instead, they would be either morally innocent preferences, or ones which put the agents in PDs. And it would then be instrumentally rational for the agents to prefer mutual co-operation. Thus if all agents initially had rationally permissible preferences and made rational choices of actions and preferences thereafter, they would never acquire immoral preferences, and so never be rationally moved to immoral actions. Further, the states of affairs such agents would be moved to bring about would be compatible with what Rawls’ agents would chose behind a veil of ignorance. Morality therefore reduces to rationality; necessarily, the actions categorically required by morality are also categorically required by rationality. (shrink)

It is widely thought that stealing, trading and destroying cultural artifacts in time of war are inherently immoral actions, and that it is right that they be treated as war crimes, which, indeed, they currently are. But oppressive cultures have their heritage and cultural artifacts too, in the form of monuments, sites of worship, and so on; and for the oppressed, these things may be awful reminders of their subordination, and may even perpetuate it. This chapter suggests that, since cultural (...) objects can be both tools and symbols of unjust oppression, their theft and destruction ought to be seen as appropriate when this would be a means of overcoming oppression. Whatever current law may say, in these instances, it would be morally inappropriate to count such acts as war crimes. Furthermore, it is bizarre that theft and destruction of cultural property are counted as war crimes when soldiers killing each other is not (due to combatant immunity). Surely killing is worse than property destruction and theft. It is therefore argued that, where possible, it would be better for conflicts to be fought using the latter methods. Finally, the chapter responds to many objections to using theft and destruction of cultural property as a method of warfare. E.g. to the objection that such property has timeless, trans-cultural, aesthetic, historical and scientific value, it is replied that justice is a more important value; and to the objection that these practices amount to cultural genocide it is replied that unjust cultures have no right to exist unmodified.

Quentin Smith argues that if God exists, He had a duty to ensure life's existence; and He couldn't rationally have done so and made a big bang unless a counter-factual like "If God had made a big bang, there would have been life," was true pre-creation. But such counter-factuals are not true pre-creation. I argue that God could have made a big bang without irrationality; and that He could have ensured life without making big bangs non-random. Further, a proper understanding (...) of the truth-conditions of counter-factuals like the one above lets them have determinate truth-values pre-creation. But the explanation of how the above counter-factual can be true pre-creation is more complicated than that offered by William Lane Craig. (shrink)

Gauthier and Hobbes reduce Prisoners Dilemmas to co-ordination problems (CPs). Many think rational, face-to-face agents can solve any CP by agreed fiat. But though an agent can rationally use a symmetry-breaking technique (ST) to decide between equal options, groups cannot unless their members' STs luckily converge. Failing this, the CP is escapable only by one agent's non-rational stubbornness, or by the group's "conquest" by an outside force. Implications: one's strategic rationality is group-relative; there are some optimums groups in principle cannot (...) rationally choose; thus justice cannot always be a rationally contracted optimum. Howard Sobel provides the point of departure. (shrink)

In Warranted Christian Beliet Alvin Plantinga claims that “The Enlightenment looked askance at testimony and tradition; Locke saw them as a preeminent source of error.” Locke, Plantinga suggests, is the “fountainhead” of this stance. This is importantly wrong about Locke and Locke”s views, and an examination of the views of Locke’s much admired friend and slightly older contemporary, Robert Boyle, reveals that the claim is mistaken about him as well, reinforcing the view that Plantinga is in general mistaken about the (...) intellectual milieu in which Locke wrote. In this paper I consider the views of Locke and Boyle on demonstration, observation, experiment, and testimony with a view to showing what, in the case of science and religion, their views actually were. For Locke I draw mainly on the Essay, while for Boyle I draw heavily on the MSS in the Royal Society Library, as well as on the printed works. (shrink)
