I assess the debate over the Suicide Machine Argument. There are several lessons to be learned from this debate. First, there is a fruitful distinction to be made,between tensed and tenseless versions of presentism, despite the temptation to suppose that presentism is a tensed theory of time. Second, once we’ve made the distinction between different kinds of presentism, it is clear that Licon’s objection protects the tenseless version of presentism from the Suicide Machine Argument; (...) however, the argument is still effective against the tensed version. Finally, I argue that if the presentist wants to remain a card carrying presentist, in the face of the challenge posed by Hales, then she must abandon her commitment to tense. (shrink)

Democracy can be a means to independently valuable ends and/or it can be intrinsically (or non-instrumentally) valuable. One powerful non-instrumental defence of democracy is based on the idea that only it can publicly justify political authority. I contend that this is an argument about the reasonable acceptability of political authority and about the requirements of publicity and that satisfying these requirements has nothing to do with whether a society is democratic or not. Democracy, then, plays no role in publicly (...) justifying political authority. I also show that any non-instrumental defence of democracy must make claims about what justice requires and make several further claims that require substantial justification. (shrink)

Steven Hales constructs a novel argument against the possibility of presentist time travel called the suicide machine argument. Hales argues that if presentism were true, then time travel would result in the annihilation of the time traveler. But such a consequence is not time travel, therefore presentism cannot allow for the possibility of time travel. This paper argues that in order for the suicide machine argument to succeed, it must make (at least) one (...) of two assumptions, each of which beg the question. The argument must either assume that the sequence of moments is invariant, or that time travel requires distinct, co-instantiated moments. Because the former disjunct assumes that presentist time travel is impossible and the latter assumes that presentism is impossible, the suicide machine argument fails. (shrink)

In this paper, I defend my original objection to Hales’ suicide machine argument against Hales’ response. I argue Hales’ criticisms are either misplaced or underestimate the strength of my objection; if the constraints of the original objection are respected, my original objection blocks Hales’ reply. To be thorough, I restate an improved version of the objection to the suicide machine argument. I conclude that Hales fails to motivate a reasonable worry as to the supposed (...) suicidal nature of presentist time travel. (shrink)

In advanced technological societies there is growing concern about the prospect of protracted deaths marked by incapacitation, intolerable pain and indignity, and invasion by machines and tubing. Life prolongation for critically ill cancer patients in the United States, for example, literally costs a fortune for very little benefit, typically from $82,845 to $189,339 for an additional year of life. Those who return home after major interventions live on average only 3 more months; the others live out their days in a (...) hospital intensive care unit. (shrink)

In this paper I defend the compossibility of presentism and time travel from two objections. One objection is that the presentist’s model of time leaves nowhere to travel to; the second objection attempts to equate presentist time travel with suicide. After targeting some misplaced scrutiny of the first objection, I show that presentists have the resources to account for the facts that make for time travel on the traditional Lewisian view. In light of this ability, I argue that both (...) of the objections fail. (shrink)

In “Should We Impose Quotas? Evaluating the ‘Disparate Impact’ Argument Against Legalization of Assisted Suicide,” Ronald Lindsay argues that it should make no difference to the debate over legalizing assisted suicide whether the risks associated with legalization would fall disproportionately on the poor, people with disabilities, racial minorities, or any other especially vulnerable social group. Even assuming such an inequitable distribution of risks would occur, he maintains, attempting to avoid such an outcome is not a good reason (...) to deny assisted suicide to “competent persons who truly voluntarily choose it.”Those of us who worry that legalization will differentially burden already disadvantaged segments of society have generally taken it for granted that the possibility of such disparities raises significant public policy concerns. By insisting on an explanation of this assumption — and, in so doing, making explicit the tension between autonomy and equality that underlies the assisted suicide debate — Lindsay has significantly advanced the ongoing conversation. While I disagree with his analysis, I commend him for a thoughtful, provocative, and important contribution to the literature. (shrink)

In I used Turing machine arguments to show that computers can recognize humanly recognizable patterns in principle. In 1978 James D. Heffernan has expressed some doubts about such arguments. He does not question the propositions that I defend in the paper, nor the specific arguments in their support. What he does criticize are certain background assumptions.

In this article I explore various facets of Nozick’s famous thought experiment involving the experience machine. Nozick’s original target is hedonism—the view that the only intrinsic prudential value is pleasure. But the argument, if successful, undermines any experientialist theory, i.e. any theory that limits intrinsic prudential value to mental states. I first highlight problems arising from the way Nozick sets up the thought experiment. He asks us to imagine choosing whether or not to enter the machine and (...) uses our choice (or rather the choice he assumes most people will have) as evidence against experientialist theories. But for this strategy to succeed it must be possible to distinguish between self-interested and non-self-interested reasons for declining to enter the machine, and there is no obvious way to do this without begging the question against the hedonist. In successive sections I then (a) consider a common misconception of Nozick’s conclusion (that he thinks machine life is the worst life), (b) consider different intuitions about what is important to well-being but missing from machine life, and finally (c) explain what “the experience requirement” is, and describe its relationship to debates about experientialist theories.

:In a recent paper in Nature1 entitled The Moral Machine Experiment, Edmond Awad, et al. make a number of breathtakingly reckless assumptions, both about the decisionmaking capacities of current so-called “autonomous vehicles” and about the nature of morality and the law. Accepting their bizarre premise that the holy grail is to find out how to obtain cognizance of public morality and then program driverless vehicles accordingly, the following are the four steps to the Moral Machinists argument:1)Find out what (...) “public morality” will prefer to see happen.2)On the basis of this discovery, claim both popular acceptance of the preferences and persuade would-be owners and manufacturers that the vehicles are programmed with the best solutions to any survival dilemmas they might face.3)Citizen agreement thus characterized is then presumed to deliver moral license for the chosen preferences.4)This yields “permission” to program vehicles to spare or condemn those outside the vehicles when their deaths will preserve vehicle and occupants.This paper argues that the Moral Machine Experiment fails dramatically on all four counts.

The Experience Machine The experience machine is a thought experiment first devised by Robert Nozick in the 1970s.

Prominent among the arguments against the legalization of assisted suicide is the contention that legalization will have a disproportionately adverse, or “disparate,” impact on various vulnerable groups. There are many versions of this argument, with different advocates of this argument focusing on different vulnerable groups, and some advocates confusedly blending slippery slope and social justice concerns. Also, the weight placed on this argument by its various advocates is not uniform, with some including the argument in (...) a list of multiple, apparently similarly persuasive, reasons for not legalizing assisted suicide, while others place significant reliance on it and yet others advance the argument without any clear indication of its importance. Nonetheless, the various versions share a common core: One reason assisted suicide should not be legalized is that members of certain vulnerable groups are more likely to be pressured into requesting it, whether directly by those hostile or indifferent to their interests, or indirectly by social circumstances, such as an inability to pursue other healthcare choices.

Since the beginning of the twenty-first century there has been an increasing awareness that software rep- resents a blind spot in new media theory. The growing interest in software also influences the argument in this paper, which sets out from the assumption that Alan M. Turing's concept of the universal machine, the first theoretical description of a computer program, is a kind of bachelor machine. Previous writings based on a similar hypothesis have focused either on a comparison (...) of the universal machine and the bachelor machine in terms of the similarities of their structural features, or they have taken the bachelor machine as a metaphor for a man or a computer. Unlike them, this paper stresses the importance of the con- text as a key to interpreting the universal Turing machine as a bachelor machine and, potentially, as a self-portrait. (shrink)

Most people who endorse physician-assisted suicide are against commercially assisted suicide – a suicide assisted by professional non-medical providers against payment. The article questions if this position – endorsement of physician-assisted suicide on the one hand and rejection of commercially assisted suicide on the other hand – is a coherent ethical position. To this end the article first discusses some obvious advantages of commercially assisted suicide and then scrutinizes six types of argument about (...) whether they can justify the rejection of commercially assisted suicide while simultaneously endorsing physician-assisted suicide. The conclusion is that they cannot provide this justification and that the mentioned position is not coherent. People who endorse physician-assisted suicide have to endorse commercially assisted suicide as well, or they have to revise their endorsement of physician-assisted suicide. (shrink)

The properties of Turing’s famous ‘universal machine’ has long sustained functionalist intuitions about the nature of cognition. Here, I show that there is a logical problem with standard functionalist arguments for multiple realizability. These arguments rely essentially on Turing’s powerful insights regarding computation. In addressing a possible reply to this criticism, I further argue that functionalism is not a useful approach for understanding what it is to have a mind. In particular, I show that the difficulties involved in distinguishing (...) implementation from function make multiple realizability claims untestable and uninformative. As a result, I conclude that the role of Turing machines in philosophy of mind needs to be reconsidered. (shrink)

In his article “On Mechanical Recognition” R. J. Nelson brings to bear a branch of mathematical logic called automata theory on problems of artificial intelligence. Specifically he attacks the anti-mechanist claim that “[i]nasmuch as human recognition to a very great extent relies on context and on the ability to grasp wholes with some independence of the quality of the parts, even to fill in the missing parts on the basis of expectations, it follows that computers cannot in principle be programmed (...) to recognize or learn to recognize all patterns”, p. 24). Nelson proposes, contrary to this claim, that “gestalt recognition is not beyond digital automata”. in particular, he claims, he will establish by what he calls “Turing machine arguments” that the following four theses are true: automata can recognize different pattern types in one and the same set of instances;automata can recognize the “same” pattern in different sets of instances;automata can recognize incomplete, degraded patterns having missing or indeterminate parts;automata can recognize family resemblances.

Objections to the computational theory of cognition, inspired by twentieth century phenomenology, have tended to fixate on the embodiment and embeddedness of intelligence. In this paper I reconstruct a line of argument that focusses primarily on the abstract nature of scientific models, of which computational models of the brain are one sort. I observe that the critique of scientific abstraction was rather commonplace in the philosophy of the 1920s and 30s and that attention to it aids the reading of (...) The Organism ([1934] 1939) by the neurologist Kurt Goldstein. With this background in place, we see that some brief but spirited criticisms of cybernetics by two later thinkers much influenced by Goldstein, Georges Canguilhem (1963) and Maurice Merleau-Ponty (1961), show continuity with the earlier discussions of abstraction in science.

When in 1979 Zenon Pylyshyn, associate editor of Behavioral and Brain Sciences (BBS, a peer commentary journal which I edit) informed me that he had secured a paper by John Searle with the unprepossessing title of [XXXX], I cannot say that I was especially impressed; nor did a quick reading of the brief manuscript -- which seemed to be yet another tedious "Granny Objection"[1] about why/how we are not computers -- do anything to upgrade that impression.

The first aim of the paper is to proffer a series of objections to the God machine thought experiment, as presented by Savulescu and Persson, The Monist, 95, 399-421,. The second aim is to show that these objections must be overcome by any form of direct moral intervention by technological means, not just the God machine. The objections raised against the god machine involve questioning its intelligibility in light of established views on the relationship between beliefs, desires, (...) intention and intentional action, pointing out the seeming inability of individuals to attribute warranted moral praise to others or themselves in the case of abstentions from grossly immoral acts identifying a problematic ‘slippery slope’ argument, and questioning the rationale underlying the Freedom Lover’s intention to enrol on a moral enhancement course, as well as arguing that that Savulescu and Persson’s notion of ‘complete freedom’ is too stringent.

Money isn’t everything, so what is? Many government leaders, social policy theorists, and members of the general public have a ready answer: happiness. This paper examines an opposing view due to Robert Nozick, which centres on his experience-machine thought experiment. Despite the example's influence among philosophers, the argument behind it is riddled with difficulties. Dropping the example allows us to re-version Nozick's argument in a way that makes it far more forceful - and less dependent on people's (...) often divergent intutions about the experience machine.

According to the “discrimination argument,” it would be discriminatory and hence impermissible to categorically exclude people with mental illness (PMI) from access to assisted suicide (AS) if AS is accessible to people with somatic illnesses. In objection to this, it could be argued that excluding PMI is not discriminatory, but rather based on their inability to meet certain eligibility criteria for AS. Which criteria are deemed necessary depends on the approach taken to justifying AS. In this article, we (...) describe two distinct ethical approaches to justifying AS and the eligibility criteria they entail and examine whether PMI can fulfill these criteria. A widespread “joint” approach based on beneficence and autonomy assumes that AS is justified when it alleviates the severe and irremediable suffering of a person who autonomously requests AS. An alternative, exclusively autonomy‐based approach assumes that providing AS is justified when a person's request is autonomous, regardless of whether AS is in her best interests. The latter approach underlies an important judgment of the German Federal Constitutional Court from 2020. We argue that PMI can in principle fulfill both beneficence‐ and autonomy‐based eligibility criteria for AS, and that a blanket exclusion of all PMI from AS is thus discriminatory on either approach. However, depending on which approach is taken, there are differences regarding the subgroups of PMI that would be eligible for AS. Whether the exclusion of specific PMI is discriminatory therefore depends on how we understand and justify AS. (shrink)

This paper reassesses the criticism of the Lucas-Penrose anti-mechanist argument, based on Gödel’s incompleteness theorems, as formulated by Krajewski : this argument only works with the additional extra-formal assumption that “the human mind is consistent”. Krajewski argues that this assumption cannot be formalized, and therefore that the anti-mechanist argument – which requires the formalization of the whole reasoning process – fails to establish that the human mind is not mechanistic. A similar situation occurs with a corollary to (...) the argument, that the human mind allegedly outperforms machines, because although there is no exhaustive formal definition of natural numbers, mathematicians can successfully work with natural numbers. Again, the corollary requires an extra-formal assumption: “PA is complete” or “the set of all natural numbers exists”. I agree that extra-formal assumptions are necessary in order to validate the anti-mechanist argument and its corollary, and that those assumptions are problematic. However, I argue that formalization is possible and the problem is instead the circularity of reasoning that they cause. The human mind does not prove its own consistency, and outperforms the machine, simply by making the assumption “I am consistent”. Starting from the analysis of circularity, I propose a way of thinking about the interplay between informal and formal in mathematics. (shrink)

In this paper reling on Agamben’s genealogical endeavour with regard to the concept of oath, I shall try to discuss how he renders the relation between language and the destituent power that will lead me to address ‘the new experience of the word’, namely, pistis (faith), which is placed at the centre of the messianic announcement. In order to open up this point, I will take into consideration Jacques Derrida’s arguments related to faith and language which appear to be one (...) of the main addressees of Agamben’s critical undertaking, even though he is never mentioned in Agamben’s later book The Sacrament of Language, in which he elaborates the contours of the relation between language and pistis. For Derrida the opening of language is based on an oath, a promise of saying ‘yes’ and thus, speaking is an act of faith. However, it is this functioning of language that has to be suspended according to Agamben, since it is this very dispositif that is connected to sovereign power. It is through this suspension the living being who has language may cease to be homo sacer before language and sovereign power. (shrink)

Neural decoding studies seem to show that the “private” experiences of others are more accessible than philosophers have traditionally believed. While these studies have many limitations, they do demonstrate that by capturing patterns in brain activity, we can discover a great deal about what a subject is experiencing. We present a thought experiment about a super-decoder — the Atlantis machine — and argue that given plausible assumptions, an Atlantis machine could one day be built. On the basis of (...) this argument, we then argue for the rejection of robust notions of consciousness, which have generated numerous puzzles, including puzzles about the possibility of philosophical zombies. In light of the Atlantis machine, it can be seen that robust notions of consciousness do not earn their explanatory or descriptive keep. More modest concepts of consciousness are sufficient to account for all phenomena — in both senses of the term. This kind of antirobustness about consciousness is a deflationary approach to conscious experience that differs in important ways from illusionist approaches. (shrink)

I argue that John Searle's (1980) influential Chinese room argument (CRA) against computationalism and strong AI survives existing objections, including Block's (1998) internalized systems reply, Fodor's (1991b) deviant causal chain reply, and Hauser's (1997) unconscious content reply. However, a new ``essentialist'' reply I construct shows that the CRA as presented by Searle is an unsound argument that relies on a question-begging appeal to intuition. My diagnosis of the CRA relies on an interpretation of computationalism as a scientific theory (...) about the essential nature of intentional content; such theories often yield non-intuitive results in non-standard cases, and so cannot be judged by such intuitions. However, I further argue that the CRA can be transformed into a potentially valid argument against computationalism simply by reinterpreting it as an indeterminacy argument that shows that computationalism cannot explain the ordinary distinction between semantic content and sheer syntactic manipulation, and thus cannot be an adequate account of content. This conclusion admittedly rests on the arguable but plausible assumption that thought content is interestingly determinate. I conclude that the viability of computationalism and strong AI depends on their addressing the indeterminacy objection, but that it is currently unclear how this objection can be successfully addressed.

Prudential hedonism has been beset by many objections, the strength and number of which have led most modern philosophers to believe that it is implausible. One objection in particular, however, is nearly always cited when a philosopher wants to argue that prudential hedonism is implausible—the experience machine objection to hedonism. This paper examines this objection in detail. First, the deductive and abductive versions of the experience machine objection to hedonism are explained. Following this, the contemporary responses to each (...) version of the argument are assessed and the deductive version is argued to be relatively ineffective compared to the abductive version. Then, a taxonomy of the contemporary critical responses to the abductive version is created. Consideration of these responses shows that the abductive version of the objection is fairly powerful, but also that one type of response seems promising against it. This response argues that experience machine thought experiments seem to elicit judgments that are either too biased to be used as evidence for the objection or not obviously in favour of reality. It is argued that only this type of refutation seems likely to convince proponents of the abductive version that the objection is much weaker than they believe it to be. Finally, it is suggested that more evidence is required before anything definitive can be said on the matter. (shrink)

Nozick's well-known Experience Machine argument can be considered a typically successful argument: as far as I know, it has not been discussed much and has been widely seen as conclusive, or at least convincing enough to refute the mental-state versions of utilitarianism. I believe that if his argument were conclusive, its destructive effect would be even stronger. It would not only refute mental-state utilitarianism, but all theories considering a certain subjective mental state as the only valuable (...) state. I shall call these theories "mental state welfarist theories." I do not know whether utilitarianism or, in general, mental-state welfarism is plausible, but I doubt that Nozick's argument is strong enough to prove that it is not. (shrink)

This paper is a warning that objections based on thought experiments can be misleading because they may elicit judgments that, unbeknownst to the judger, have been seriously skewed by psychological biases. The fact that most people choose not to plug in to the Experience Machine in Nozick’s (1974) famous thought experiment has long been used as a knock-down objection to hedonism because it is widely thought to show that real experiences are more important to us than pleasurable experiences. This (...) paper argues that the commonplace choice to remain in reality when offered a life in the Experience Machine is best explained by status quo bias – the irrational preference for things to remain the same. An alternative thought experiment, empirical evidence, and discussion of how psychological biases can affect our judgments are provided to support this argument. (shrink)

This essay explores a series of sovereign ‘machines’ – slaves, puppets, automata – in political theory from Benjamin to Agamben. It is now well-documented that the philosophical question of ‘the machine’ – of whether a complex system requires a human operator or whether it can function autonomously – is also a crucial political question that haunts every discussion of sovereignty from Hobbes onwards. However, my wager in what follows is that this machine is not just a metaphor for (...) a metaphysical situation – whether it be rationality, bureaucratization, neutralization, historicism or governmentality – but a material phenomenon that carries transformative political promise and threat. To summarize the argument of this essay, I contend that ‘sovereign machines’ like slavery, puppets, automata or clockwork, lens, optics and mirrors (Hobbes, Kantorowicz, Benjamin, Lacan,... (shrink)

According to the standard no miracles argument, science’s predictive success is best explained by the approximate truth of its theories. In contemporary science, however, machine learning systems, such as AlphaFold2, are also remarkably predictively successful. Thus, we might ask what best explains such successes. Might these AIs accurately represent critical aspects of their targets in the world? And if so, does a variant of the no miracles argument apply to these AIs? We argue for an affirmative answer (...) to these questions. We conclude that if the standard no miracles argument is sound, an AI-specific no miracles argument is also sound. (shrink)

ABSTRACTIn this paper, I examine the arguments against physician assisted suicide . Many of these arguments are consequentialist. Consequentialist arguments rely on empirical claims about the future and thus their strength depends on how likely it is that the predictions will be realized. I discuss these predictions against the backdrop of Oregon's Death with Dignity Act and the practice of PAS in the Netherlands. I then turn to a specific consequentialist argument against PAS – Susan M. Wolf's feminist (...) critique of the practice. Finally, I examine the two most prominent deontological arguments against PAS. Ultimately, I conclude that no anti‐PAS argument has merit. Although I do not provide positive arguments for PAS, if none of the arguments against it are strong, we have no reason not to legalize it. (shrink)

Since the noun phrase `artificial intelligence' (AI) was coined, it has been debated whether humans are able to create intelligence using technology. We shed new light on this question from the point of view of themodynamics and mathematics. First, we define what it is to be an agent (device) that could be the bearer of AI. Then we show that the mainstream definitions of `intelligence' proposed by Hutter and others and still accepted by the AI community are too weak even (...) to capture what is involved when we ascribe intelligence to an insect. We then summarise the highly useful definition of basic (arthropod) intelligence proposed by Rodney Brooks, and we identify the properties that an AI agent would need to possess in order to be the bearer of intelligence by this definition. Finally, we show that, from the perspective of the disciplines needed to create such an agent, namely mathematics and physics, these properties are realisable by neither implicit nor explicit mathematical design nor by setting up an environment in which an AI could evolve spontaneously.

Searle has long maintained a position that non-biologically based machines , no matter how intelligently they may appear to behave, cannot achieve “intentionality” or “consciousness,” have a “mind,” and so forth. Standard replies to Searle’s argument, as commonly cited by researchers in Artificial Intelligence and related communities, are sometimes considered unsatisfactory by readers outside of such fields. One possible reason for this is that the Chinese Room Argument makes a strong appeal to some people’s intuitions regarding “understanding” and (...) necessary conditions for consciousness. Rather than contradict any such intuitions or conditions, I present what in my view is an independent and largely compatible intuition: If Searle’s argument is sound, then surely a human placed under similar testing conditions as a non-biological machine should succeed where a machine would allegedly fail. The outcome is a new rebuttal to the Chinese Room that is ideologically independent of one’s views on the necessary and sufficient conditions for having a “mind.”. (shrink)

There are 1,000 of us and one victim. We each increase the level at which a "discomfort machine" operates on the victim---leading to great discomfort. Suppose that consecutive levels of the machine are so similar that the victim cannot distinguish them. Have we acted permissibly? According to the "no-difference argument" the answer is "yes" because each of our actions was guaranteed to make the victim no worse off. This argument is of interest because if it is (...) sound, similar arguments threaten intuitive moral verdicts about many cases in which a large number of individual choices cumulatively make a great difference, while each choice seems to make no difference on its own. But the argument is not sound, as is shown by a simple objection based on a plausible dominance principle---an objection that avoids challenges that have been brought against previous criticisms of the no difference argument.

This book is a colorful journey into the fascinatingly diverse world of interneurons, an important class of highly heterogeneous cells found in all cortical neuronal networks. Interneurons are known to play key roles in many brain functions, from sensory processing to neuronal oscillations linked to learning and memory. The central aim of the volume is to provide new insights into the striking degree of cellular diversity found in interneuronal microcircuits. The book discusses the history of research into interneuronal variability, the (...) developmental origins of interneuronal diversity, the functional roles of heterogeneity in neuronal circuits, contemporary interneuronal classification systems, and the genetic and homeostatic mechanisms that shape the degree of cell to cell variability within interneuronal populations. It elaborates on new ideas about interneuronal diversity that rest upon theoretical and experimental results, with arguments touching upon evolution, animal behavior, and the mathematical theory of small world networks. This engaging volume is invaluable to neuroscientists and others interested in how neuronal newtworks function; electrical engineers, computational modelers, and physicists interested in neuronal network theory; neurologists and psychiatrists working on mechanisms of neurological and psychiatric disorders; and students and trainees in all of these fields.

Robert Nozick's experience machine thought experiment (Nozick's scenario) is widely used as the basis for a ?knockdown? argument against all internalist mental state theories of well-being. Recently, however, it has been convincingly argued that Nozick's scenario should not be used in this way because it elicits judgments marred by status quo bias and other irrelevant factors. These arguments all include alternate experience machine thought experiments, but these scenarios also elicit judgments marred by status quo bias and other (...) irrelevant factors. In this paper, several experiments are conducted in order to create and test a relatively bias-free experience machine scenario. It is argued that if an experience machine thought experiment is used to evaluate internalist mental state theories of well-being, then this relatively bias-free scenario should be used over any of the existing scenarios. Unlike the existing experience machine scenarios, when this new scenario is used to assess internalist mental state theories of well-being, it does not provide strong evidence to refute or endorse them.

Years ago Robert Nozick provided the experience machine argument, which states that since many people would forgo a life of artificially stimulated tremendous pleasure provided by an "experience machine," it must be that sometimes people are motivated by things other than the pursuit of their own pleasure.

In a recent book Elliot Sober and David Wilson defend the view that Nozick's argument does not provide adequate refutation of (...) psychological hedonism. This article defends Nozick's argument against their objections. (shrink)

There are striking differences between Camus’s early and late philosophical essays, but Camus often claimed that his works were part of one consistent project. This paper argues that, although Camus had a significant change in his views on the consequences of the absurd, throughout his life he also had a common concern with the relation of the absurd to morality. Showing this requires us to clarify what Camus meant by the “absurd,” and identify at least three different uses of the (...) term by Camus: lacking a purpose; lacking an explanation; and a tension between purpose and purposelessness. Clarifying the meaning of “absurd” allows one to show that Camus’s late argument against suicide, often dismissed as inadequate, is valid. This also illustrates the consistency of his concerns over time. (shrink)
