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)

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 identity, and that, (...) therefore, the endurance of violence of liberal states/societies is dependent upon mechanisms of active blindness. 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)

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)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 63.4 (2002) 555-575 [Access article in PDF] Measurer of All Things:John Greaves (1602-1652), the Great Pyramid, and Early Modern Metrology Zur Shalev [Figures]Writing from Istanbul to Peter Turner, one of his colleagues at Merton College, Oxford, John Greaves was deeply worried: Onley I wonder that in so long time since I left England I should neither have received my brasse quadrant which (...) I left to be finished for my journey thither, nor any notice of it [...]. I agreed with mr. Allen upon price and the time that he should finish it, if he hath failed me he hath done me the greatest injury that can be. 1A great injury indeed, because Greaves's journey to Italy and the Levant was all about measuring—luckily the instrument did reach him at some later stage. The thirty-six-year-old Professor of Geometry at Gresham College was taking the measurements of countless monuments and objects in the locations he visited. In Rome he measured, among many other ancient structures, Cestius' Pyramid and St. Peter's basilica. In Lucca, deeply impressed, he counted his paces around the beautiful city walls. In Siena he observed together with a "Mathematical Professor" one of the Sidera Medicea using "a glass." In Egypt he even hurt his eyes gazing at the sun, looking for sunspots and measuring its diameter. 2 His measuring mission, however, culminated in the fixing of the [End Page 555] latitudes of Istanbul, Rhodes, and Alexandria. As Bishop Juxton wrote before the trip to Greaves's employers at Gresham College (apparently using Greaves's own promotional language): This worke I find by the best astronomers, especially by Ticho Brache [ sic ] and Kepler, hath beene much desired as tending to the advancement of that science, and I hope it wil be an honour to that nation and prove ours if we first observe it. 3A mathematician-Orientalist, commanding the ancient and modern astronomical and geographical literature of Latin, Greek, Hebrew, Arabic, and Persian authors, Greaves was arguably the best qualified European at the period to perform the task. That he miscalculated the latitude of Rhodes is of less consequence for his present-day readers. 4 However, one of the most obscure and therefore telling of his measurement activities was the survey of the Pyramids of Giza, which resulted in the Pyramidographia (1646). 5 This remarkable learned treatise and travel account hybrid, which is at the focus of the present study, gives us a glimpse into the rich and complex world of scientific antiquarians.Greaves is most conveniently remembered today as an Orientalist. While we must be thankful to Edward Said for broadening the meaning of Orient-alism—from an academic discipline, accumulating objective knowledge of the East, into a much wider cultural discourse, his emphasis on the nineteenth and twentieth centuries and on the European colonial mindset is less useful for making historical sense of what early modern Orientalists were doing—physically and culturally. We can understand Greaves's "Oriental" enterprise in its [End Page 556] depth and variety only within long established European traditions of scholarship and keeping the intellectual concerns of his time in mind. 6But beyond articulating for us the nature of early Orientalism, the Pyramidographia, as well as Greaves's entire scientific career, situated in their wider European context, provide a fine entry point into a foreign world of learned practices and methods. It teaches us how well into the seventeenth century astronomy and philology, observation and bookishness, could coalesce in one figure, in one enterprise. 7 We still lack a modern biography of Greaves, a complex protagonist of a complex period, and even a full evaluation of his intellectual work. While this paper surely cannot compensate for that, I do attempt here a brief exposition of Greaves's Pyramidographia. 8Modern historians of archaeology and Egyptology, preoccupied mostly with the disciplines' progress and development of scientific standards, have noted the Pyramidographia in passing and praised its precise language and rigorous research...

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.

It is proved that for every positive integer n, the number of non-Tukey-equivalent directed sets of cardinality $\leq \aleph _n$ is at least $c_{n+2}$, the $(n+2)$ -Catalan number. Moreover, the class $\mathcal D_{\aleph _n}$ of directed sets of cardinality $\leq \aleph _n$ contains an isomorphic copy of the poset of Dyck $(n+2)$ -paths. Furthermore, we give a complete description whether two successive elements in the copy contain another directed set in between or not.

A recent attempt to compute a (recursion‐theoretic) noncomputable function using the quantum adiabatic algorithm is criticized and found wanting. Quantum algorithms may outperform classical algorithms in some cases, but so far they retain the classical (recursion‐theoretic) notion of computability. A speculation is then offered as to where the putative power of quantum computers may come from.

In this paper I investigate responses to sentence (“yes-no”) questions in Greek dialogue which are neither a clear-cut ‘yes’ nor a ‘no’. I describe, classify, and discuss a range of patterns for expressing this strategy of indirectness, beginning with an example termed μέση ἀπόκρισις in the commentary of Olympiodorus to Plato Gorgias. Ancient rhetorical sources also discuss strategies for evading clear-cut non-polar responses to sentence questions in sections on the notion of ἀπόκρισις (and ἐρώτησις) without a fixed terminology. The fabricated (...) and quoted examples which these ancient sources give, serve as a point of departure for my classification of patterns in occurrences collected from literary dialogues (selections from Plato, and a corpus study of the Greek comedies of Aristophanes and Menander). The analysis of mechanisms for these non-polar responses draws on philological as well as linguistic scholarship from Greek antiquity through contemporary dialogue analysis, and refers also to contexts and conventions of characterization in Ancient Greek sources.

We consider bargaining situations where two players evaluate outcomes with reference-dependent utility functions, analyzing the effect of differing levels of loss aversion on bargaining outcomes. We find that as with risk aversion, increasing loss aversion for a player leads to worse outcomes for that player in bargaining situations. An extension of Nash's axioms is used to define a solution for bargaining problems with exogenous reference points. Using this solution concept we endogenize the reference points into the model and find a (...) unique solution giving reference points and outcomes that satisfy two reasonable properties, which we predict would be observed in a steady state. The resulting solution also emerges in two other approaches, a strategic (non-cooperative) approach using Rubinstein's (1982) alternating offers model and a dynamic approach in which we find that even under weak assumptions, outcomes and reference points converge to the steady state solution from any non-equilibrium state.

Quantum computers are hypothetical quantum information processing (QIP) devices that allow one to store, manipulate, and extract information while harnessing quantum physics to solve various computational problems and do so putatively more efficiently than any known classical counterpart. Despite many ‘proofs of concept’ (Aharonov and Ben–Or 1996; Knill and Laflamme 1996; Knill et al. 1996; Knill et al. 1998) the key obstacle in realizing these powerful machines remains their scalability and susceptibility to noise: almost three decades after their conceptions, experimentalists (...) still struggle to maintain useful quantum coherence in QIP devices with more than a pair of qubits (e.g., Blatt and Wineland 2008). This slow progress has prompted debates on the feasibility of quantum computers, yet the quantum information community has dismissed the skepticism as “ideology” (Aaronson 2004), claiming that the obstacles are merely technological (Kaye et al. 2007, 240). In a recent paper (Hagar 2009) I’ve argued that such a skepticism with respect to the feasibility of quantum computers need not be deemed ideological at all, and that the aforementioned ‘proofs of concept’ are physically suspect. Using analogies from the foundations of classical statistical mechanics (SM), I’ve also argued that instead of active error correction, the appropriate framework for debating the feasibility of large–scale, fault–tolerant and computationally superior quantum computers should be the project of error avoidance: rather than trying to constantly ‘cool down’ the QIP device and prevent its thermalization, one should try to locate those regions in the device’s state space which are thermodynamically ‘abnormal’, i.e., those regions in the device’s state space which resist thermalization regardless of external noise. This paper is intended as a further contribution to the debate on the feasibility of large–scale, fault–tolerant and computationally superior quantum computers. Relying again on analogies from the foundations of classical SM, it suggests a skeptical conjecture and frames it in the ‘passive’, error avoidance, context.. (shrink)

It is occasionally claimed that the important work of philosophers, physicists, and mathematicians in the nineteenth and in the early twentieth centuries made Kant’s critical philosophy of geometry look somewhat unattractive. Indeed, from the wider perspective of the discovery of non-Euclidean geometries, the replacement of Newtonian physics with Einstein’s theories of relativity, and the rise of quantificational logic, Kant’s philosophy seems “quaint at best and silly at worst”.1 While there is no doubt that Kant’s transcendental project involves his own conceptions (...) of Newtonian physics, Euclidean geometry and Aristotelian logic, the issue at stake is whether the replacement of these conceptions collapses Kant’s philosophy into an unfortunate embarrassment.2 Thus, in evaluating the debate over the contemporary relevance of Kant’s philosophical project one is faced with the following two questions: (1) Are there any contradictions between the scientific developments of our era and Kant’s philosophy? (2) What is left from the Kantian legacy in light of our modern conceptions of logic, geometry and physics? Within this broad context, this paper aims to evaluate the Kantian project vis à vis the discovery and application of non-Euclidean geometries. Many important philosophers have evaluated Kant’s philosophy of geometry throughout the last century,3 but opinions with regard to the impact of non-Euclidean geometries on it diverge. In the beginning of the century there was a consensus that the Euclidean character of space should be considered as a consequence of the Kantian project, i.e., of the metaphysical view of space and of the synthetic a priori character of geometry. The impact of non-Euclidean geometries was then thought as undermining the Kantian project since it implied, according to positivists such.. (shrink)

Relying on the universality of quantum mechanics and on recent results known as the “threshold theorems,” quantum information scientists deem the question of the feasibility of large‐scale, fault‐tolerant, and computationally superior quantum computers as purely technological. Reconstructing this question in statistical mechanical terms, this article suggests otherwise by questioning the physical significance of the threshold theorems. The skepticism it advances is neither too strong (hence is consistent with the universality of quantum mechanics) nor too weak (hence is independent of technological (...) contingencies). *Received June 2009; revised August 2009. †To contact the author, please write to: Department of History and Philosophy of Science, College of Arts and Sciences, Indiana University, Bloomington, IN 47405; e‐mail: [email protected].

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)

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.

I discuss the philosophical implications that the rising new science of quantum computing may have on the philosophy of computer science. While quantum algorithms leave the notion of Turing-Computability intact, they may re-describe the abstract space of computational complexity theory hence militate against the autonomous character of some of the concepts and categories of computer science.

I discuss a rarely mentioned correspondence between Einstein and Swann on the constructive approach to the special theory of relativity, in which Einstein points out that the attempts to construct a dynamical explanation of relativistic kinematical effects require postulating a fundamental length scale in the level of the dynamics.

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)

A recent proposal to solve the halting problem with the quantum adiabatic algorithm is criticized and found wanting. Contrary to other physical hypercomputers, where one believes that a physical process “computes” a (recursive-theoretic) non-computable function simply because one believes the physical theory that presumably governs or describes such process, believing the theory (i.e., quantum mechanics) in the case of the quantum adiabatic “hypercomputer” is tantamount to acknowledging that the hypercomputer cannot perform its task.

The early history of the attempts to unify quantum theory with the general theory of relativity is depicted through the work of the under--appreciated Italo-Brazilian physicist Gleb Wataghin, who is responsible for many of the ideas that the quantum gravity community is entertaining today.

One of the recurrent problems in the foundations of physics is to explain why we rarely observe certain phenomena that are allowed by our theories and laws. In thermodynamics, for example, the spontaneous approach towards equilibrium is ubiquitous yet the time-reversal-invariant laws that presumably govern thermal behaviour in the microscopic level equally allow spontaneous departure from equilibrium to occur. Why are the former processes frequently observed while the latter are almost never reported? Another example comes from quantum mechanics where the (...) formalism, if considered complete and universally applicable, predicts the existence of macroscopic superpositions—monstrous Schr¨odinger cats—and these are never observed: while electrons and atoms enjoy the cloudiness of waves, macroscopic objects are always localized to definite positions.

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.

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.

Among the alternatives of non-relativistic quantum mechanics (NRQM) there are those that give different predictions than quantum mechanics in yet-untested circumstances, while remaining compatible with current empirical findings. In order to test these predictions, one must isolate one’s system from environmental induced decoherence, which, on the standard view of NRQM, is the dynamical mechanism that is responsible for the ‘apparent’ collapse in open quantum systems. But while recent advances in condensed-matter physics may lead in the near future to experimental setups (...) that will allow one to test the two hypotheses, namely genuine collapse vs. decoherence, hence make progress toward a solution to the quantum measurement problem, those philosophers and physicists who are advocating an information-theoretic approach to the foundations of quantum mechanics are still unwilling to acknowledge the empirical character of the issue at stake. Here I argue that in doing so they are displaying an unwarranted double standard. r 2007 Elsevier Ltd. All rights reserved. (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, 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’, and the other is regulatory power, 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)

This essay traces the evocations of the Chinese practice of foot-binding in Western political thought. I examine the changing deployments of the image: as a contrast to European freedom or as a mirror reflecting its own limitations. The bound feet not merely illustrate a lack of freedom through an image of disabled mobility. They also situate freedom within global and gendered frameworks. Via a reading of the image and its contexts, we see that European freedom-as-movement emerged on the backdrop of (...) two imperial contrasts: images of nomadism, which are only marginally considered in this paper, and an assumed stagnation, that presumably prevailed in the East. Yet surprisingly, the image was often evoked to say something about Europe itself, rather than about its “others.” Therefore, it also reveals the corporeal dimensions of a concept of freedom that has underlaid a long liberal tradition. The crushed and squeezed feet of girls in China thus marked both a gendered and an imperial divide between those who can move freely, and therefore rule, and those who cannot rule because of their lack of mobility; yet at the same time, it undid this division by allowing the East and its stationariness to permeate Europe through a multiply foreign body: feminized, racially alien, and geographically distanced.

In the chapter “The Geometry of Visibles” in his ‘Inquiry into the Human Mind’, Thomas Reid constructs a special space, develops a special geometry for that space, and offers a natural model for this geometry.

By reviewing Reid’s ideas on visible space and confronting him with Kant and Berkeley, I hope, moreover, to resolve an alleged impasse in (...)

We present a brief history of decoherence, from its roots in the foundations of classical statistical mechanics, to the current spin bath models in condensed matter physics. We analyze the philosophical import of the subject matter in three different foundational problems, and find that, contrary to the received view, decoherence is less instrumental to their solutions than it is commonly believed. What makes decoherence more philosophically interesting, we argue, are the methodological issues it draws attention to, and the question of (...) the universality of quantum mechanics. (shrink)

For many among the scientifically informed public, and even among physicists, Heisenberg's uncertainty principle epitomizes quantum mechanics. Nevertheless, more than 86 years after its inception, there is no consensus over the interpretation, scope, and validity of this principle. The aim of this chapter is to offer one such interpretation, the traces of which may be found already in Heisenberg's letters to Pauli from 1926, and in Dirac's anticipation of Heisenberg's uncertainty relations from 1927, that stems form the hypothesis of finite (...) nature. Instead of a mere mathematical theorem of quantum theory, or a manifestation of "wave-particle duality", the uncertainty relations turn out to be a result of a more fundamental premise, namely, the inherent limitation on spatial resolution that follows from the bound on physical resources. The implication of this view are far reaching: it depicts the Hilbert space formalism as a phenomenological, "effective", formalism that approximates an underlying discrete structure; it supports a novel interpretation of probability in statistical physics that sees probabilities as deterministic, dynamical transition probabilities which arise from objective and inherent measurement errors; and it helps to clarify several puzzles in the foundations of statistical physics, such as the status of the "disturbance" view of measurement in quantum theory, or the tension between ontology and epistemology in the attempts to describe nature with physical theories whose formalisms include subjective probabilities. Finally, this view also renders obsolete the entire class of interpretations of quantum theory that adhere to "the reality of the wave function". (shrink)

In the latter half of the 20th century, Western medicine moved death from the home to the hospital. As a result, the process of dying seems to have lost its spiritual dimension, and become a matter of prolonging material life by means of medical technology. The novel quandaries that arose led in turn to medico-legal regulation. This paper describes the recent regulation of dying in Israel under its Dying Patient Law, 2005. The Law recognizes advance directives in principle, but limits (...) their effect and form through complex medico-legal artifices. It reflects a culture that places high value on both scientific medicine and the sanctity of life as such, and illustrates a medical culture that pitches battle against death. At the same time, the Law constructs the will of the individual in a medico-legal language that is alien to the lay person. The paper suggests an alternative approach to advance care planning that is patient-centred and addresses the psycho-social needs of the individual in terms of her relational autonomy. From this perspective, advance care planning becomes an opportunity to extract the patient from the medical context and allow her to speak about her approaching death with close ones in her own terms of reference. To this end, there is a need for facilitation of an intimate encounter where patients can speak about their concerns with their loved ones. The paper also presents a methodological approach of attentive listening, which can be applied across diverse cultures and circumstances. (shrink)

The military service of combat soldiers may pose many threats to their well being and often take a toll on body and mind, influencing the physical and emotional make-up of combatants and veterans. The current study aims to enhance our knowledge about the combat experiences and the challenges that female soldiers face both during and after their service. The study is based on qualitative methods and narrative analysis of in-depth semi-structured personal interviews with twenty military veterans. It aims to analyze (...) the narratives of American and Israeli female combat soldiers regarding their military service, with emphasis on the soldiers’ descriptions, in their own words, about their difficulties, challenges, coping and successes during their service and transition to civilian life. A recurring theme in the interviews with the veterans of both militaries was the need to be heard and the fact that societies, therapists, and military institutions do not always truly listen to female veterans’ experiences and are not really interested in what actually ails them. Our research suggests that conventional methods used in research relating to veterans might at times be inadequate, because the inherent categorization might abstract, pathologize, and fragment a wide array of soldiers’ modes of post-combat being. Moreover, female veterans’ voices will not be fully heard unless we allow them to be active participants in generating knowledge about themselves. (shrink)

Scientific realism is dead, or so many philosophers believe. Its death was announced when philosophers became convinced that one can accept all scientific results without committing oneself to metaphysical existence claims about theoretical entities (Fine 1986, 112).

This is a retrospective of surrogacy in Israel in the context of medically assisted reproduction. The practice of surrogacy emerged in the 1980s, suggesting a radical view of women as autonomous reproductive agents free from double standards of patriarchy. In 1995 Israel enacted a law that regulated domestic surrogacy for the benefit of infertile married women in accord with orthodox views of halakha. In recent years we see the growth of inter-country practices catering to otherwise ineligible intended parents, and a (...) demand for posthumous male reproduction. Meanwhile, women become objects of intrusive medical procedures and commodities of a global market, more often than not for the benefit of others rather than themselves. Yet the essence of human reproduction remains relational, and calls for care and responsibility. (shrink)
