Saul Smilansky presents an original new approach to the problem of free will, which lies at the heart of morality and self-understanding. He maintains that the key to the problem is the role played by illusion. Smilansky boldly claims that we could not live adequately with a complete awareness of the truth about human freedom and that illusion lies at the center of the human condition.

Recent suggestions to supply quantum mechanics (QM) with realistic foundations by reformulating it in light of quantum information theory (QIT) are examined and are found wanting by pointing to a basic conceptual problem that QIT itself ignores, namely, the measurement problem. Since one cannot ignore the measurement problem and at the same time pretend to be a realist, as they stand, the suggestions to reformulate QM in light of QIT are nothing but instrumentalism in disguise.

Loop quantum gravity predicts that spatial geometry is fundamentally discrete. Whether this discreteness entails a departure from exact Lorentz symmetry is a matter of dispute that has generated an interesting methodological dilemma. On one hand one would like the theory to agree with current experiments, but, so far, tests in the highest energies we can manage show no such sign of departure. On the other hand one would like the theory to yield testable predictions, and deformations of exact Lorentz symmetry (...) in certain yet– to–be–tested regimes may have phenomenological consequences. Exposing their shortcomings, here I discuss two arguments that exemplify this dilemma, and compare them to other cases from the history of physics that share their symptoms. (shrink)

Drawing on feminist and queer critiques that see violence as constitutive of identities, this essay points to subject-positions whose construction is necessarily conditioned by exercising violence. Focusing on settler colonialism, I reverse the optics of the first set of critiques: rather than seeing the self as taking form through the injuries she suffers, I try to understand selves that are structurally constituted by causing injury to others. This analysis refuses the assumption that violence is in conflict with (liberal) identity, and (...) that, therefore, the endurance of violence of liberal states/societies is dependent upon mechanisms of active blindness (or denial, deferral, and other forms of dissociation). I argue that this assumption, which is shared by many critiques of violence, fails to perceive that people can desire the violent arrangements supporting their communities. They therefore fail to address political settings wherein violence is an affirmative element of political identities. (shrink)

I shall argue that compatibilism cannot resist in a principled way the temptation to prepunish people. Compatibilism thus emerges as a much more radical view than it is typically presented and perceived, and is seen to be at odds with fundamental moral intuitions.

Denialism concerning free will and moral responsibility combines, in its minimal form, the rejection of libertarian free will and the rejection of compatibilism. I will address the more ambitiously “happy” or “optimistic” version of denialism, which also claims that we are better off without belief in free will and moral responsibility, and ought to try to radically reform our moral, social and personal lives without such beliefs. I argue that such denialism involves, for various reasons, a dangerous gamble, which it (...) would be morally irresponsible to follow. I conclude by reflecting upon the implications. (shrink)

Combining physics, mathematics and computer science, quantum computing and its sister discipline of quantum information have developed in the past few decades from visionary ideas to two of the most fascinating areas of quantum theory. General interest and excitement in quantum computing was initially triggered by Peter Shor (1994) who showed how a quantum algorithm could exponentially “speed-up” classical computation and factor large numbers into primes far more efficiently than any (known) classical algorithm. Shor’s algorithm was soon followed by several (...) other algorithms that aimed to solve combinatorial and algebraic problems, and in the years since theoretical study of quantum systems serving as computational devices has achieved tremendous progress. Common belief has it that the implementation of Shor’s algorithm on a large scale quantum computer would have devastating consequences for current cryptography protocols which rely on the premise that all known classical worst-case algorithms for factoring take time exponential in the length of their input (see, e.g., Preskill 2005). Consequently, experimentalists around the world are engaged in attempts to tackle the technological difficulties that prevent the realisation of a large scale quantum computer. But regardless whether these technological problems can be overcome (Unruh 1995; Ekert and Jozsa 1996; Haroche and Raimond 1996), it is noteworthy that no proof exists yet for the general superiority of quantum computers over their classical counterparts. -/- The philosophical interest in quantum computing is manifold. From a social-historical perspective, quantum computing is a domain where experimentalists find themselves ahead of their fellow theorists. Indeed, quantum mysteries such as entanglement and nonlocality were historically considered a philosophical quibble, until physicists discovered that these mysteries might be harnessed to devise new efficient algorithms. But while the technology for harnessing the power of 50–100 qubits (the basic unit of information in the quantum computer) is now within reach (Preskill 2018), only a handful of quantum algorithms exist, and the question of whether these can truly outperform any conceivable classical alternative is still open. From a more philosophical perspective, advances in quantum computing may yield foundational benefits. For example, it may turn out that the technological capabilities that allow us to isolate quantum systems by shielding them from the effects of decoherence for a period of time long enough to manipulate them will also allow us to make progress in some fundamental problems in the foundations of quantum theory itself. Indeed, the development and the implementation of efficient quantum algorithms may help us understand better the border between classical and quantum physics (Cuffaro 2017, 2018a; cf. Pitowsky 1994, 100), and perhaps even illuminate fundamental concepts such as measurement and causality. Finally, the idea that abstract mathematical concepts such as computability and complexity may not only be translated into physics, but also re-written by physics bears directly on the autonomous character of computer science and the status of its theoretical entities—the so-called “computational kinds”. As such it is also relevant to the long-standing philosophical debate on the relationship between mathematics and the physical world. (shrink)

We live within political systems that increasingly seek to control movement, organized around both the desire and ability to determine who is permitted to enter what sorts of spaces, from gated communities to nation-states. In _Movement and the Ordering of Freedom_, Hagar Kotef examines the roles of mobility and immobility in the history of political thought and the structuring of political spaces. Ranging from the writings of Locke, Hobbes, and Mill to the sophisticated technologies of control that circumscribe the (...) lives of Palestinians in the Occupied West Bank, this book shows how concepts of freedom, security, and violence take form and find justification via “regimes of movement.” Kotef traces contemporary structures of global mobility and resistance to the schism in liberal political theory, which embodied the idea of “liberty” in movement while simultaneously regulating mobility according to a racial, classed, and gendered matrix of exclusions.

I distinguish between two concepts of effort, E-effort and T-effort. E-effort is the familiar one, which focuses on the experiential qualities of making an effort (such the energy and time we put into effort making, or the hardship we endure). Teleological effort (or T-effort) is the motivated and active focus on the intended purpose or goal of the effort; the aim to do what it takes to reach the target of the effort. When we make a T-effort we concentrate on (...) the best way of getting to where we want to be, which may involve putting in less E-effort. Focusing upon T-efforts should help us both to better understand the relationship between effort and success; and to make what I call Real Efforts. (shrink)

In a previous work I considered the philosophically neglected phenomenon of “Fortunate Misfortune” (or FM). This follows from the way in which sometimes what seems an obvious misfortune turns out, in fact, to be actually good fortune. The paradox, in a certain class of cases, is this: if a seemingly unfortunate aspect of a life has proven to be beneficial overall, then it has not been a real misfortune. However, certain aspects of actual lives seem to be obvious misfortunes, irrespective (...) of what follows. Often, saying both that the life-aspects under consideration are misfortunes and denying that they are, seem unacceptable. In the present paper I aim to survey some of the conceptual, moral and social implications of cases of Fortunate Misfortune. This will be mostly done in the form of questions, exploring the perplexities FM brings up and the challenges it hence poses for further work. (shrink)

I describe a case involving two countries at war, Benevolentia and Malevoran. Malevoran is an unjust aggressor, which does not follow the requirements of the prevailing morality of warfare. The leadership and army of Benevolentia closely follow those requirements, and as a direct result Benevolentia loses. I claim that this is a reductio of the prevailing morality of warfare: in the victory of Malevoran over Benevolentia morality has lost. I draw some tentative conclusions concerning the morality of warfare, and urge (...) that we need to gain a richer understanding of what it means for morality to win, see this as a distinct and important moral consideration, and think afresh how morality can triumph much more often. (shrink)

It is commonly thought that morality applies universally to all human beings as moral targets, and our general moral obligations to people will not, as a rule, be affected by their views. I propose and explore a radical, alternative normative moral theory, ‘Designer Ethics’, according to which our views are pro tanto crucial determinants of how, morally, we ought to be treated. For example, since utilitarians are more sympathetic to the idea that human beings may be sacrificed for the greater (...) good, perhaps it is permissible to give them ‘priority’ as potential victims. This odd idea has manifold drawbacks but I claim that it also has substantial advantages, that it has some affinities to more commonly accepted moral positions, and that it should be given a significant role in our ethical thinking.

The past is full of terrible tragedies, including slavery, World War I, and the Holocaust. Morality would clearly appear to support the preference that the victims of those calamities would have lived free and peaceful lives. And yet, a puzzle or even a paradox appears to be lurking here. Moral evaluation can be either personal or impersonal, yet neither one of these two perspectives, nor any other prevalent moral evaluation of events, appears to yield the morally expected conclusion. To the (...) best of my knowledge this puzzle has not been discussed before. If there is no way to escape this surprising conclusion, then morality appears to be much more grim and unsympathetic than we normally think. (shrink)

Bernard Williams once said that doing moral philosophy could be hazardous because there, presumably unlike in other areas of philosophy, we may run the risk of misleading people on important matters.1 This risk seems to be particularly present when considering the topic of terrorism. I would like to discuss what seems to be a most striking feature of contemporary terrorism, a feature that, as far as I know, has not been noted. This has implications concerning the way that we should (...) view terrorism (and counterterrorism) and shows the force of a number of neglected illusions surrounding the issue of terrorism, as well as its justification.

In Free Will, Agency, and Meaning in Life, Derk Pereboom proposes an optimistic model of life that follows on the rejection of both libertarian and compatibilist beliefs in free will, moral responsibility, and desert. I criticize his views, focusing on punishment. Pereboom responds to my earlier argument that hard determinism must seek to revise the practice of punishment in the direction of funishment, whereby the incarcerated are very generously compensated for the deprivations of incarceration. I claimed that funishment is a (...) practical reductio: of hard determinism. Pereboom replies, but I claim that he misses a key component of my reductio, the idea that moving in the direction of funishment will considerably weaken the deterrence of potential criminals so that hard determinism becomes self-defeating in practice. Beyond the challenge of funishment, I raise various other difficulties with Pereboom’s model, concerning its deeply unintuitive implications, the harm it does to the motivation of potential criminals, its weakness in resisting utilitarian-like dangers, and more. Our conclusions should lead to a re-evaluation of the compatibilist interpretation of moral life, as a richer, more plausible, and safer interpretation than hard determinism. This needs to be combined with a true hard determinist acknowledgment of the deep injustice and tragedy involved in punishment in light of the absence of libertarian free will. Such a complex view will come closer to doing justice to notions of justice, morality, and decency. (shrink)

In his recent monumental book On What Matters, Derek Parfit argues for a hard determinist view that rejects free will-based moral responsibility and desert. This rejection of desert is necessary for his main aim in the book, the overall reconciliation of normative ethics. In Appendix E of his book, however, Parfit claims that it is possible to mete out fair punishment. Parfit’s position on punishment here seems to be inconsistent with his hard determinism. I argue that Parfit is mistaken here, (...) in a way that leads him to unjustified optimism about the possibility of fair penalization. Insofar as we take the free will problem seriously, we cannot reconcile a belief in the absence of desert with a belief in the fairness of penalization. (shrink)

ABSTRACT All ethical systems seem to call for more ethical sensitivity. The dangers to personal life of too much ethical sensitivity have received much attention lately, in attempts to limit the demands of morality. But the ethical dangers of ethical sensitivity have hardly been noticed. I argue that, in a number of different ways, too much ethical sensitivity can be ethically harmful. The normative, the psychological and the pragmatic pictures are for more complex than is commonly realised.

In Smilansky (1996) I proposed an outline of a theory of responsibility and desert, which I claimed both (a) enables us to see responsibility as a condition for desert even in the major apparent counter-examples such as those proposed in Feldman (1995); and (b) represents the ordinary way of seeing the connection between responsibility and desert better than previous formulations. Behind this proposal lies a crucial distinction between two ways in which responsibility can be a condition for desert. From (...) Feldman’s reply (1996) it seems that this crucial distinction was not suffi- ciently brought out in my paper. (shrink)

A remarkable theorem by Clifton, Bub and Halvorson (2003) (CBH) characterizes quantum theory in terms of information--theoretic principles. According to Bub (2004, 2005) the philosophical significance of the theorem is that quantum theory should be regarded as a ``principle'' theory about (quantum) information rather than a ``constructive'' theory about the dynamics of quantum systems. Here we criticize Bub's principle approach arguing that if the mathematical formalism of quantum mechanics remains intact then there is no escape route from solving the measurement (...) problem by constructive theories. We further propose a (Wigner--type) thought experiment that we argue demonstrates that quantum mechanics on the information--theoretic approach is incomplete. (shrink)

An analysis of the two routes through which one may disentangle a quantum system from a measuring apparatus, hence protect the state vector of a single quantum system from being disturbed by the measurement, reveals several loopholes in the argument from protective measurement to the reality of the state vector of a single quantum system.

Huw Price (1996, 2002, 2003) argues that causal-dynamical theories that aim to explain thermodynamic asymmetry in time are misguided. He points out that in seeking a dynamical factor responsible for the general tendency of entropy to increase, these approaches fail to appreciate the true nature of the problem in the foundations of statistical mechanics (SM). I argue that it is Price who is guilty of misapprehension of the issue at stake. When properly understood, causal-dynamical approaches in the foundations of SM (...) offer a solution for a different problem; a problem that unfortunately receives no attention in Price’s celebrated work.

I point out an odd consequence of the role that broadly pragmatic considerations regularly play in determining moral demands. As a result of the way in which moral demands are formed, it turns out that people will frequently become morally good in a strange and rather dubious way. Because human beings are not very good, we will lower our moral demands and, as a result, most people will turn out, in an important sense, to be morally good. Our relative badness, (...) by giving us good reasons to limit moral demands, makes us morally good. (shrink)

This article examines the cultural ways in which traditional Judaism understands the relationship between an individual and Divinity. The article shows that this understanding has deep gendered dimensions. Grounded in feminist critiques of theology, as well as in Jewish studies and cultural studies, the article shows that the conceptualization of God-person relationship, in both Orthodox and Kaballic Jewish streams, is based on a hierarchical division to three different spaces. These spaces are: Mitzvah, Grace, and Desire or Will. The Mitzvah is (...) perceived to be the highest space and is represented as 'manly'. The intermediate space-Grace-is represented as a 'good woman' or as 'mother'. This space is characterized by a sacred yearning, as well as by lack of stability and continuity, paralysis, and even death. The lowest space is the space of Desire and personal will, which is culturally represented by a child or a whore-woman. This space is characterized by an attitude of disregard, resistance and fear. The article demonstrates how this cultural division of Divinity in to three, contradicts the declared Jewish position that God/divinity is 'One, Sole and Unique', and points at the inherent need of genderless conceptualization of Divinity in Judaism.

One defining feature of the Hindu religious worldviews is a belief in the impermanence of the body and its perception as a source of suffering due to a misguided attachment of the self to its corporeal manifestation. This view is expressed in several important traditions, including classical yoga, which perceives the physical body as an impediment to attaining liberation and irrelevant in the state of liberation.However, the perception of the physical body in liberation is going through ontological changes in early (...) medieval Haṭhayoga texts. The dichotomy between embodied and disembodied states of the body when one is liberated is the focus of this article. In several medieval yoga texts dating between the eleventh and the fifteenth centuries, the ontological immortal state of living liberation is more similar to physical death. Often the exact text holds both views of embodied and disembodied states simultaneously with no overt inconsistency. I argue that these tensions and contradictions can be explained in two ways: by looking at the assessed timeline of the texts and by reflecting on their sectarian and social origin. (shrink)

W chwilach szczególnego zagrożenia ludzie zwykle błagają Boga o pomoc dla siebie lub swoich bliskich, modląc się na przykład, żeby lawina zmieniła kierunek lub żeby znalazł się dawca organów dla czyjegoś umierającego dziecka. Taka modlitwa wydaje się naturalna, a dla wierzących nawet rozumna i akceptowalna. Niestosowne wydaje się potępianie takiej typowej modlitwy jako czegoś złego. Ale kiedy dokładnie zbadać, co się rzeczywiście dzieje w takich sytuacjach, to okazuję się, że często tego rodzaju modlitwa jest moralnie dyskusyjna. Autor twierdzi, że taka (...) modlitwa powinna być postrzegana jako forma działania, a tym samym powinna spełniać wysokie standardy moralne, które odnoszą się do działań; ponadto autor twierdzi, że założenie dobroczynności Bóstwa nie wystarcza, aby taką modlitwę legitymizować.

I consider two difficulties which have been presented to egalitarianism: Parfit’s “Levelling Down Objection” and my “Paradox of the Baseline”. I show that making things worse for some people even with no gain to anyone is actually an ordinary and indeed necessary feature of our moral practice, yet nevertheless the LDO maintains its power in the egalitarian context. I claim that what makes the LDO particularly forceful in the case against egalitarianism is not the very idea of making some people (...) worse off with no gain to others, but the disrespect for value inherent in egalitarianism; and similarly that the POB is a reductio of choice -egalitarianism because of its inversion of the intuitively correct attitude to the generation of value. I conclude that in the light of the absurdity and paradox so frequently lurking in moral and social life, and particularly with the complexity of modern life and obliquity of change, we need to be much more modest than egalitarians have been in putting forth ambitious moral and social models.

First let's see what a paradox is. Broadly speaking, there are two opinions. One is lax; it is common among non-philosophers, but occasionally comes up in philosophy as well. According to the lax view, a paradox (or the paradoxical – there is a distinction, but I will not make it here) can be anything perplexing, unusual, unexpected, or ironic. The strict view closely connects paradoxes to the idea of a contradiction. Mark Sainsbury in PARADOXES defines it thus: “an apparently unacceptable (...) conclusion derived by apparently acceptable reasoning from apparently acceptable premises” (1996:1). (shrink)

Looking at one site, the Israeli checkpoints in the occupied Palestinian territory, this article seeks to understand the mechanisms by which violence can present itself as justifiable (or justified), even when it materializes within frames presumably set to annul it. We look at the checkpoints as a condensed microcosmos operating within two such frames. One is the prolonged Israeli-Palestinian ‘peace process’ (the checkpoints became a primary technology of control in the period following the beginning of the peace process), and the (...) other is regulatory power (disciplinary and biopower), which in the Foucauldian framework presumably sidelines the violent form which sovereign power takes. We argue that the checkpoints, which dissect the Palestinian occupied territories into dozens of enclaves and which are one of the most effective and destructive means of control within the current stage of occupation, can be seen as more than obstacles in the way of Palestinian movement; we suggest that they also function as corrective technologies that are meant to fail. It is with this failure that violence can appear as justified. In order to show the operation of this embedded failure, we examine one mechanism operating within the checkpoints: ‘the imaginary line’. The imaginary line is both a component within, and an emblem of a mode of control that constantly undoes itself in order to summon violence. Since it is never visibly marked in the physical space, the imaginary line is bound to be unintentionally crossed, thereby randomly rendering Palestinians as ‘transgressors’ of the rule and thus facilitating eruptions of violence by the soldiers stationed at the checkpoints. This article proposes an analysis of this hidden demarcation of space in order to question the different relations between subjects and power which it both assumes and constitutes. (shrink)
