ABSTRACTThe quartz clock, the first to replace the pendulum as the time standard and later a ubiquitous and highly influential technology, originated in research on means for determining frequency for the needs of telecommunication and the interests of its users. This article shows that a few groups in the US, Britain, Italy and the Netherlands developed technologies that enabled the construction of the new clock in 1927–28. To coordinate complex and large communication networks, the monopolistic American Telephone and Telegraph Company, (...) and national laboratories needed to determine and maintain a common ‘standard’ frequency measurement unit. Exploiting novel piezoelectric quartz methods and valve electronics techniques, researchers in these organizations constructed a new crystal-based frequency standard. To ensure its accuracy they compared it to an accepted absolute standard - an astronomical clock, constructing thereby the first quartz clock. Other groups, however, had different, though connected, technological aims, which originated from the diverse interests of the industrial, governmental and academic institutes to which they belonged, and for which they needed to measure, control and manipulate with frequencies of electric oscillations. The present article suggests a comparative examination of the research and development paths of these groups on their incentives, the technological and scientific resources they utilized, and the kind of research carried out in the various institutional settings.

Historians, philosophers, and physicists portray the 1920s and 1930s as a period of major theoretical breakthrough in physics, quantum mechanics, which led to the expansion of physics into the core of the atom and the growth and strengthening of the discipline. These important developments in scientific inquiry into the micro-world and light have turned historical attention away from other significant historical processes and from other equally important causes for the expansion of physics. World War II, on the other hand, is (...) often seen as the watershed moment when physics achieved new levels of social and technical engagement at a truly industrial scale. Historians have shown that military interests and government funding have shaped physics to unprecedented degree, and according to some, to the extent of discontinuity with earlier practices of research (Forman 1987; Kevles 1990; Kaiser 2002). In this vein, Stuart Leslie wrote, “Nothing in the prewar experience fully prepared academic scientists and their institutions for the scale and scope of a wartime mobilization that would transform the university, industry, and the federal government and their mutual interrelationships” (Leslie 1993, 6). While one can never befullyready for novelties, the contributors to this issue show that developments in interwar physics did prepare participants for their cold war interactions with industry and government.

ArgumentConcentrating on the important developments of quantum physics, historians have overlooked other significant forces that shaped interwar physics, like that of technology. Based on the case of piezoelectricity, I argue that interests of users of technics (i.e. devices of methods) channeled research in physics into particular fields and questions relevant for industrial companies and governmental agencies. To recognize the effects of such social forces on physics, one needs to study the content of the scientific activity (both experimental and theoretical) of (...) the researchers within its social and disciplinary contexts. By examining paths of individual scientists along with a study of the research in the field as a whole this paper exposes a range of reasons that led researchers to studies pertinent to technics. In particular, it shows that commercial, social, and military powers shaped interwar research through institutions aimed at fostering technology, some of them newly founded, and by a general view that academic research should help technology, a position that became more common at the time.

In his recent authoritative Helmholtz and the Conservation of Energy, Kenneth Caneva has claimed that earlier authors had invoked the principle of conservation of living force only in cases of a system returning to an earlier state, or of one without Newtonian forces. Relaying on texts in the tradition of the French Analytical Mechanics form Lagrange to Coriolis, I argue that this was not the case, and that the principle had been formulated and used for cases where living force proper (...) (mv2) was not conserved but its sum with an integral function (refers today as potential) was constant. In addition. I show that contrary to Caneva’s claim, the principle had been connected to the impossibility of creating power out of nothing. The two points indicate a stronger link between the analytical tradition and Helmholtz and his readers than usually portrayed, and the significant contribution of mechanics to the emergence of energy conservation. On a methodological level the use of living force shows that a common term and even a concept, like energy, is not always needed for its successful employment. (shrink)

In 1918–1919 Walter G. Cady was the first to recognize the significant electrical consequences of the fact that piezoelectric crystals resonate at very sharp, precise and stable frequencies. Cady was also the first to suggest the employment of these properties, first as frequency standards and then to control frequencies of electric circuits—an essential component in electronic technology. Cady’s discovery originated in the course of research on piezoelectric ultrasonic devices for submarine detection (sonar) during World War I. However, for the discovery (...) Cady had to change his research programme to crystal resonance. This change followed Cady’s experimental findings and the scientific curiosity that they raised, and was helped by the termination of the war. Cady’s transition was also a move from “applied” research, aimed at improving a specific technology, to “pure” research lacking a clear practical aim. This article examines how Cady reached the discovery and his early ideas for its use. It shows that the discovery was not an instantaneous but a gradual achievement. It further suggests that disinterested “scientific” research (rather than “engineering” research) was needed in this process, while research aimed at design was required for the subsequent development of technological devices.

Summary Between 1911 and 1914, Owen Richardson formulated a theory of photoelectricity based on thermodynamics and statistical reasoning. Although this theory succeeded in accounting for most of the relevant phenomena and despite the lack of competing causal or descriptive accounts of the phenomena, it failed to attract other physicists. This paper seeks the reasons for the neglect of this theory in contemporary cultures of photoelectric research. Four main causes of neglect are identified: the relatively high number and the nature of (...) the theory's assumptions, the contradiction of one of these assumptions with contemporary views, the failure to suggest new predictions or to account for hitherto unexplained regularities, and the view shared by many scientists that the problem of electromagnetic radiation required a radical solution that a descriptive theory could not provide. The expectation for a radical solution defines the revolutionary character of a research field. In the case of photoelectricity, it originated in a web of evidence to which other fields contributed. The very possibility of Richardson's theory shows that, taken separately, this phenomenon could receive an account which, unlike Einstein's light quantum, did not require deep changes in the conception of nature.

Exact measurements are a central practice of modern physics. In certain cases, they are essential for determining values of coefficients, for confirming theories, and for detecting the existence of effects. The history of piezoelectricity at the end of the nineteenth century reveals two different methods of exact measurement: a mathematical versus an “artisanal” approach. In the former, a scientist first carried out the experiment and later employed mathematical methods to reduce error. In the latter, a scientist physically manipulated the experimental (...) apparatus to bypass possible sources of error before its performance. These two approaches were related to German theoreticians and to French experimentalists, respectively. However, affiliation with a particular school rather than nationality was the decisive factor in the differences between the two approaches. Despite differences, adherents of both approaches sought to attain high precision and to eliminate even small experimental errors. This history exhibits the complexity and flexibility of experiments and their analysis. It supports the claim of the “New Experimentalism” that theory does not supply complete directions for practical experimental decisions. An example for this is found in the way an experimental error was discovered only by a comparison to an earlier experiment rather than to a theory. (shrink)

This book demonstrates that we need not choose between seeing so-called Presocratic thinkers as rational philosophers or as religious sages. In particular, it rethinks fundamentally the emergence of systematic epistemology and reflection on speculative inquiry in Hesiod, Xenophanes and Parmenides. Shaul Tor argues that different forms of reasoning, and different models of divine disclosure, play equally integral, harmonious and mutually illuminating roles in early Greek epistemology. Throughout, the book relates these thinkers to their religious, literary and historical surroundings. It (...) is thus also, and inseparably, a study of poetic inspiration, divination, mystery initiation, metempsychosis and other early Greek attitudes to the relations and interactions between mortal and divine. The engagements of early philosophers with such religious attitudes present us with complex combinations of criticisms and creative appropriations. Indeed, the early milestones of philosophical epistemology studied here themselves reflect an essentially theological enterprise and, as such, one aspect of Greek religion. (shrink)

Developers are often the engine behind the creation and implementation of new technologies, including in the artificial intelligence surge that is currently underway. In many cases these new technologies introduce significant risk to affected stakeholders; risks that can be reduced and mitigated by such a dominant party. This is fully recognized by texts that analyze risks in the current AI transformation, which suggest voluntary adoption of ethical standards and imposing ethical standards via regulation and oversight as tools to compel developers (...) to reduce such risks. However, what these texts usually sidestep is the question of how aware developers are to the risks they are creating with these new AI technologies, and what their attitudes are towards such risks. This paper asks to rectify this gap in research, by analyzing an ongoing case study. Focusing on six Israeli AI startups in the field of radiology, I carry out a content analysis of their online material in order to examine these companies’ stances towards the potential threat their automated tools pose to patient safety and to the work-standing of healthcare professionals. Results show that these developers are aware of the risks their AI products pose, but tend to deny their own role in the technological transformation and dismiss or downplay the risks to stakeholders. I conclude by tying these findings back to current risk-reduction recommendations with regards to advanced AI technologies, and suggest which of them hold more promise in light of developers’ attitudes.

This article argues that Empedocles’ trust in Strife (DK31 B115.14 = LM22 D10.14) is not, as the prevailing interpretation has it, only a past misjudgement and failure. Rather, trust in Strife still, and to his own lament, infects Empedocles’ mind and informs his life. This detail then offers a fresh perspective on Empedocles’ self-conception and on how, through the daimōn’s cosmic peregrinations, Empedocles raises and pursues questions of agency and responsibility. Furthermore, it sheds light on Empedocles’ understanding of his own (...) ethical standing: common assumptions to the contrary notwithstanding, he does not see himself as an unqualifiedly successful embodiment of his own ideals.

Scalar implicatures depend on alternatives in order to avoid the symmetry problem. I argue for a structure-sensitive characterization of these alternatives: the alternatives for a structure are all those structures that are at most as complex as the original one. There have been claims in the literature that complexity is irrelevant for implicatures and that the relevant condition is the semantic notion of monotonicity. I provide new data that pose a challenge to the use of monotonicity and that support the (...) structure-sensitive definition. I show that what appeared to be a problem for the complexity approach is overcome once an appropriate notion of complexity is adopted, and that upon closer inspection, the argument in favor of monotonicity turns out to be an argument against it and in favor of the complexity approach.

Postliberal theology has been a topic of considerable theological debate over the past few decades. In his 2011 book Another Reformation, Peter Ochs deploys a postliberal theological model for the purpose of developing a sophisticated understanding of the future of interreligious relations. Ochs argues that postliberal theology is a reparative theology focusing on alleviating human suffering. He argues that the Christian idea of supersessionism may be the most challenging for Christians to confront as they explore avenues for making interreligious dialogue (...) more effective. Ochs critiques the Mennonite theologian John Howard Yoder's understanding of Zionism as Jewish Constantianism for being an instance of an ostensibly postliberal theology losing its way. In this essay, I offer a critique of Ochs's reading of Yoder, claiming that Yoder's view actually mirrors an important intra-Jewish debate about the relationship between political power and piety, and retrieves an ingenious contribution of both early Judaism and early Christianity that is effaced in today's growing Constantinian approach to Christian imperialism and Jewish nationalism.

This contribution to the Common Knowledge symposium on xenophilia examines the life choices of two Jews who loved Christianity. Elijah Zvi Soloveitchik, born into an ultra-Orthodox, nineteenth-century rabbinic dynasty in Lithuania, spent much of his life writing a Hebrew commentary on the Gospels in order to document and argue for the symmetry or symbiosis that he perceived between Judaism and Christianity. Oswald Rufeisen, from a twentieth-century secular Zionist background in Poland, converted to Catholicism during World War II, became a monk, (...) and attempted to immigrate to Israel as a Jew in 1958. Rufeisen, while permitted to move to Israel to join a Carmelite monastery in Haifa, was denied the right to immediate citizenship of Israel which the Law of Return guarantees to all bona fide Jews. And this particular Soloveitchik has largely been forgotten, given the limits of Jewish interest in the New Testament and of Christian attention to rabbinic literature. This article explores the complex and vexing questions that the careers of these two men raise about the elusive distinctions between Judaism and Christianity, on the one hand, and, on the other, between the Jewish religion and Jewish national identity.

The computation of both Scalar Implicatures (SI) and Association with Focus (AF) is characterized with reference to sets of alternatives. However, it has generally been assumed that the relevant alternatives are determined in different ways for the two processes. Specifically, it has been assumed that the alternatives for SI – scalar alternatives – are computed by a special procedure specifically designed for implicatures, whereas the alternatives for AF – focus alternatives – are determined by the general theory of association with (...) focus – focus semantics. As far as we know, the only attempt to connect the two is Krifka (1995), under which scalar alternatives and focus alternatives are identical and determined by focus semantics. However, Krifka’s result is based on a specific stipulation about scalar items, which he borrows from Horn and incorporates into focus semantics, namely that scalar items are inherently focused and have their Horn Scale as their lexically specified focus values.

The sensitivity of focus to context has often been analyzed in terms of focus-based anaphoric relations between sentences and surrounding discourse. The literature, however, has also noted empirical difficulties for the anaphoric approach, and my goal in the present paper is to investigate what happens if we abandon the anaphoric view altogether. Instead of anaphoric felicity conditions, I propose that focus leads to infelicity only indirectly, when the semantic processes that it feeds—in particular, exhaustification and question formation—make an inappropriate contribution (...) to discourse. I outline such an account, in line with Roberts (In Papers in semantics, Vol. 49 of Working papers in linguistics, 91–136, The Ohio State University, 1996 ) and incorporating recent insights from Büring (In Questions in discourse, Vol. 36 of Current research in the semantics/pragmatics interface, 6–44, Leiden: Brill, 2019 ) and Fox (In Proceedings of Sinn und Bedeutung 22, 403–434, 2019 ). This account, which I motivate on conceptual grounds, has no anaphoric conditions on focus placement and has only an economy condition as a potential felicity condition on focus. However, there are cases where the fine control offered by anaphoricity seems needed, either to block deaccenting that would be licensed by a question or to allow local deaccenting that is not warranted by a question. Such cases challenge non-anaphoric accounts such as the present one and appear to support recent anaphoric proposals such as Schwarzschild (In Making worlds accessible. Essays in honor of Angelika Kratzer, 167–192, 2020 ), Wagner (In The Wiley Blackwell companion to semantics, Oxford: Wiley-Blackwell, 2020 ), and Goodhue (Journal of Semantics 39: 117–158, 2022 ). I argue that this potential motivation for anaphoricity is only apparent and that to the extent that anaphoric conditions on focus from the literature are not inert, they are in fact harmful.

Following the lead of Duncan Pritchard’s “Wittgensteinian Pyrrhonism,” this paper takes a further, comparative and contrastive look at the problem of justification in Sextus Empiricus and in Wittgenstein’sOn Certainty. I argue both that Pritchard’s stimulating account is problematic in certain important respects and that his insights contain much interpretive potential still to be pursued. Diverging from Pritchard, I argue that it is a significant and self-conscious aspect of Sextus’ sceptical strategies to call into question large segments of our belief systemen (...) masseby exposing as apparently unjustifiable fundamental propositions which are closely related in their linchpin role to Wittgenstein’s hinge propositions. In the first instance, the result is a more complex account of both a deeper affinity between Wittgenstein’s approach to hinge propositions and Sextus’ approach to what I termarchaipropositions and a divergence between the two. In the second instance, I suggest how the comparison withOn Certaintycan be illuminating for the interpreter of Sextus. In particular, it can help us to see how the Pyrrhonist’s everyday conduct—common assumptions to the contrary notwithstanding—involves rational procedures of justification, in line with a naturalism reminiscent of Wittgenstein. Furthermore, it can help us to reflect on the Pyrrhonist’s attitude to what Wittgenstein would have called her ‘worldview’. Throughout, I suggest that the comparison with Wittgenstein is interesting, although it must be cashed out differently, not only on the interpretation—or, perhaps, strand—of ancient Pyrrhonism which has the sceptic exempt ordinary beliefs from her suspension of judgement, but also on the interpretation (or strand) which has her disavow all beliefs categorically.

_ Source: _Volume 60, Issue 1, pp 3 - 39 This paper pursues a new approach to the problem of the relation between Alētheia and Doxa. It investigates as interrelated matters Parmenides’ impetus for developing and including Doxa, his conception of the mortal epistemic agent in relation both to Doxa’s investigations and to those in Alētheia, and the relation between mortal and divine in his poem. Parmenides, it is argued, maintained that Doxastic cognition is an ineluctable and even appropriate aspect (...) of mortal life. The mortal agent, however, is nonetheless capable of sustaining the cognition of Alētheia by momentarily coming to think with—or as—his divine soul. (shrink)

We revisit a typological puzzle due to Horn (Doctoral Dissertation, UCLA, 1972) regarding the lexicalization of logical operators: in instantiations of the traditional square of opposition across categories and languages, the O corner, corresponding to ‘nand’ (= not and), ‘nevery’ (= not every), etc., is never lexicalized. We discuss Horn’s proposal, which involves the interaction of two economy conditions, one that relies on scalar implicatures and one that relies on markedness. We observe that in order to express markedness and to (...) account for a bigger typological puzzle, namely the absence of lexicalizations of ‘XOR’ (= exclusive or), ‘all-or-none’, and many other imaginable logical operators, one must restrict the basic lexicalizable elements to a small set of primitives. We suggest that an ordering based perspective, following Keenan and Faltz (Boolean semantics for natural language, 1985), makes the stipulated primitives that we arrive at more natural. We also propose a modification to Horn’s proposal, based on recent work on implicatures, in which only the implicature condition is operative and in which markedness is part of the definition of the alternatives for scalar implicatures rather than an independent condition.

This book provides the reader with a theoretical and practical understanding of two health care delivery models: the patient/child centred care and family-centred care. Both are fundamental to caring for children in healthcare organizations. The authors address their application in a variety of paediatric healthcare contexts, as well as the ethical and legal issues they raise. Each model is increasingly pursued as a vehicle for guiding the delivery of health care in the best interests of children. Such models of health (...) care delivery shape health care policies, programs, facility design, resource allocation decisions and day-to-day interactions among patients, families, physicians and other health care professionals. To maximize the health and ethical benefits these models offer, there must be shared understanding of what the models entail, as well as the ethical and legal synergies and tensions they can create. This book is a valuable resource for paediatricians, nurses, trainees, graduate students, practitioners of ethics and health policy. (shrink)

This article investigates Levinas’s readings of Plato and Descartes in Totality and Infinity, in relation to the question of teaching. Levinas identifies Plato’s Form of the Good and Descartes’s idea of the infinite as two models for his own conception of the Other. Yet while Levinas lauds Descartes’s theory of teaching, he is highly critical of Plato’s. Plato’s theory of teaching as recollection or maieutics is judged by Levinas to display merely the circular return of the Same to its own (...) interiority. In contrast, the Cartesian God supplies the idea of the infinite to a subject incapable of generating it for itself, offering an account of teaching that respects the Other’s transcendent exteriority. I nonetheless argue for the possibility of a rapprochement between Levinas and Plato with regard to teaching. Ultimately, this serves to bolster Levinas’s own theory of teaching, for which both Plato and Descartes can rightly serve as fitting predecessors. (shrink)

We present an argument for revising the theory of alternatives for Scalar Implicatures and for Association with Focus. We argue that in both cases the alternatives are determined in the same way, as a contextual restriction of the focus value of the sentence, which, in turn, is defined in structure-sensitive terms. We provide evidence that contextual restriction is subject to a constraint that prevents it from discriminating between alternatives when they stand in a particular logical relationship with the assertion or (...) the prejacent, a relationship that we refer to as symmetry. Due to this constraint on contextual restriction, discriminating between alternatives in cases of symmetry becomes the task of focus values. This conclusion is incompatible with standard type-theoretic definitions of focus values, motivating our structure-sensitive definition instead. (shrink)

This essay is a close examination of one of Nahman of Bratslav's early and largely unexamined texts, Sefer ha‐Middot. The question it addresses is whether one can call this a study of “ethics” or, in Jewish nomenclature, musar, a work that seeks to cultivate human behaviors and describe ethical formation. In addition, it asks whether Sefer ha‐Middot can be called a text of “virtue ethics” given its focus on virtues and their enactment. The essay argues that Nahman's peculiar metaphysical notion (...) that all mitzvot are inextricably intertwined prevents any analysis of behavioral causality severing his “ethics” from any Aristotelian or Kantian tradition and brings him closer to Alasdair MacIntyre's notion of ethics as tied to traditional norms. And even with MacIntyre, the comparison is quite limited. Discussing “faith,” the “zaddik,” and “money,” the essay explores Nahman's view of how these and other virtues are cultivated and achieved.

This article explores antiphilosophical polemics written by Muslim and Jewish thinkers in the medieval Mediterranean world. These writings demonstrate, in both traditions, a struggle with the incorporation of nontraditional texts and interpretations of theology and textuality. My examination of these writings “against the philosophers” suggests that, far from constituting the reflexive, antiphilosophical fundamentalism that typically characterizes assessments of these texts, authors like al-Ghazali, Halevi, and Ibn Arabi were concerned with what they believed to be the subordination of Jewish and Islamic (...) tradition to Greek philosophy—a rhetoric that, for them, undermined the “conditions of identification” for Muslims and Jews. I argue that these antiphilosophical texts highlight the extent to which these thinkers believed that writing was the battleground for identity in the medieval Middle East. (shrink)

The current study uses a repeated measures design to compare two-time points across the COVID-19 pandemic. The first was conducted at the end of the “first wave” [T1] and the second was carried out on October 12-14 2020 in Israel. The participants completed the same questionnaire at both time points. The study examined the predictions of hope and morale at T2 by psychological and demographic predictors at T1. Results indicated the following: The three types of resilience significantly and positively predicted (...) hope and morale. Well-being significantly and positively predicted hope and morale. Younger age significantly and positively predicts higher hope, but not morale. A higher level of religiosity significantly and positively predicts higher hope and morale. More right-wing political attitudes significantly and positively predict higher hope, but not moral. More economic difficulties due to the pandemic, significantly and negatively predict hope and morale. We concluded that hope and morale can serve as significant indicators of the population's ability to cope with the COVID-19 pandemic. Furthermore, they can serve as a “thermometer” for the general mood of the population and can be used by decision-makers to assess coping ability at varied stages of the pandemic. (shrink)

In this response to the essays in the symposium on my book Meir Kahane: The Public Life and Political Thought of an American Jewish Radical I tried to clarify and expand some of the thoughtful and astute themes in the remarks of my interlocutors, especially about how the book was not intended to be about one figure but rather an intervention into postwar American and Israeli Judaism through the lens of a maligned figure who is ignored by most American Jews (...) and demonized by most Israeli Jews. Meir Kahane remains present because he never went away. And he never went away because he offered solutions that, while unpopular and egregious, continue to resonate when Jews begin to feel unstable about their place in America or Israel. He is the dark underside of the modern Jewish project that will not go away. (shrink)
