Our study of a public inquiry shows how particular constructions of the older worker — as male and lacking in self-esteem — were privileged as a result of discursive manoeuvres that established comparative disadvantage among different identities. Paradoxically, traditional gender stereotypes were subverted to construct female willingness to accept low status, low paid jobs as a reason why they did not need help in the form of policy initiatives; while men's intransigence meant they deserved greater support. A second paradox (...) concerned the construction of the older worker as lacking self-esteem: it led to self-esteem based solutions that were the responsibility of the individual to remedy but, precisely because older male workers lacked self-esteem, they were unable to help themselves and needed the help of employment and welfare agencies. Thus we can see the link between particular identity constructions, discourse and the reproduction of particular institutional structures. (shrink)

This is an extended critique of comments made by Abner Shimony and Howard Stein on Henry Stapp’s proof of the non-locality of quantum mechanics. Although I claim that ultimately Stapp’s proof does not establish its purported conclusion, yet Shimony and Stein’s criticism contains a number of weak points, which need to be clarified.

Hardy’s non-locality paradox is a proof without inequalities showing that certain non-local correlations violate local realism. It is ‘possibilistic’ in the sense that one only distinguishes between possible outcomes (positive probability) and impossible outcomes (zero probability). Here we show that Hardy’s paradox is quite universal: in any (2,2,l) or (2,k,2) Bell scenario, the occurrence of Hardy’s paradox is a necessary and sufficient condition for possibilistic non-locality. In particular, it subsumes all ladder paradoxes. This universality (...) of Hardy’s paradox is not true more generally: we find a new ‘proof without inequalities’ in the (2,3,3) scenario that can witness non-locality even for correlations that do not display the Hardy paradox. We discuss the ramifications of our results for the computational complexity of recognising possibilistic non-locality. (shrink)

Hardy and Unruh constructed a family of non-maximally entangled states of pairs of particles giving rise to correlations that cannot be accounted for with a local hidden-variable theory. Rather than pointing to violations of some Bell inequality, however, they pointed to apparent clashes with the basic rules of logic. Specifically, they constructed these states and the associated measurement settings in such a way that the outcomes satisfy some conditionals but not an additional one entailed by them. Quantum mechanics avoids (...) the broken ‘if …then …’ arrows in such Hardy–Unruh chains, as we call them, because it cannot simultaneously assign truth values to all conditionals involved. Measurements to determine the truth value of some preclude measurements to determine the truth value of others. Hardy–Unruh chains thus nicely illustrate quantum contextuality: which variables do and do not obtain definite values depends on what measurements we decide to perform. Using a framework inspired by Bub and Pitowsky and developed in our book Understanding Quantum Raffles (co-authored with Michael E. Cuffaro), we construct and analyze Hardy–Unruh chains in terms of fictitious bananas mimicking the behavior of spin-1/2 particles. (shrink)

Hardy’s paradox was originally presented as a demonstration, without inequalities, of the incompatibility between quantum mechanics and the hypothesis of local causality. Equipped with newly developed tools that allow for a quantitative assessment of realism, here we revisit Hardy’s paradox and argue that nonlocal causality is not mandatory for its solution; quantum irrealism suffices.

Hardy’s nonlocality is a “nonlocality proof without inequalities”: it exemplifies that quantum correlations can be qualitatively stronger than classical correlations. This paper introduces variants of Hardy’s nonlocality in the CHSH scenario which are realized by the PR-box, but not by quantum correlations. Hence this new kind of Hardy-type nonlocality is a proof without inequalities showing that superquantum correlations can be qualitatively stronger than quantum correlations.

Parallel lives is a model which provides an interpretation of quantum theory that is both local and realistic. This model assumes that all quantum fields are composed of point beings called “lives”. Lives interact locally and have a memory of their previous interactions. The reduction of the state vector is not included in this model: lives can be divided into different worlds. This feature resembles many worlds interpretation. However in the parallel lives model, the division of lives into different worlds (...) takes place locally. The parallel lives model is expected to be compatible with special relativity, as the lives propagate at a speed that does not exceed the speed of light and interact locally. On the other hand, it is open to paradoxes based on counterfactual propositions, as it provides a realistic interpretation of quantum theory. In this paper, we confront the parallel lives model with the paradox proposed by Hardy. We show that the parallel lives model cannot overcome the dilemma in Hardy’s paradox. We discuss implications of this confrontation on special theory of relativity, and speculate a solution that we believe, fits the spirit of the parallel lives model. (shrink)

In this paper, we strengthen Hardy’s [1995] and Ketland’s [2005] arguments on the issues surrounding the self-referential nature of Yablo’s paradox [1993]. We first begin by observing that Priest’s [1997] construction of the binary satisfaction relation in revealing a fixed point relies on impredicative definitions. We then show that Yablo’s paradox is ‘ω-circular’, based on ω-inconsistent theories, by arguing that the paradox is not self-referential in the classical sense but rather admits circularity at the least transfinite (...) countable ordinal. Hence, we both strengthen arguments for the ω-inconsistency of Yablo’s paradox and present a compromise solution of the problem emerged from Yablo’s and Priest’s conflicting theses. (shrink)

Klyachko and coworkers consider an orthogonality graph in the form of a pentagram, and in this way derive a Kochen-Specker inequality for spin 1 systems. In some low-dimensional situations Hilbert spaces are naturally organised, by a magical choice of basis, into SO(N) orbits. Combining these ideas some very elegant results emerge. We give a careful discussion of the pentagram operator, and then show how the pentagram underlies a number of other quantum “paradoxes”, such as that of Hardy.

A so called “weak value” of an observable in quantum mechanics (QM) may be obtained in a weak measurement + post-selection procedure on the QM system under study. Applied to number operators, it has been invoked in revisiting some QM paradoxes (e.g., the so called Three-Box Paradox and Hardy’s Paradox). This requires the weak value to be interpreted as a bona fide property of the system considered, a par with entities like operator mean values and eigenvalues. I (...) question such an interpretation; it has no support in the basic axioms of quantum mechanics and it leads to unreasonable results in concrete situations. (shrink)

In the paper we will employ set theory to study the formal aspects of quantum mechanics without explicitly making use of space-time. It is demonstrated that von Neuman and Zermelo numeral sets, previously efectively used in the explanation of Hardy’s paradox, follow a Heisenberg quantum form. Here monadic union plays the role of time derivative. The logical counterpart of monadic union plays the part of the Hamiltonian in the commutator. The use of numerals and monadic union in the (...) classical probability resolution of Hardy’s paradox [1] is supported with the present derivation of a commutator for sets. (shrink)

We claim that the Universe’s fundamental structure is not discoverable through rationalism. The various frameworks studied are logic, mathematics, their application through theories in physics, and finally, the pivotally separate application of logic to historical evidence in formal religious belief. The basis of the prohibition is that rational structure has a limit for consistency that falls short of completeness in absolute terms. The limit of observability reaches only a framework in which correlated elements are formed paradoxically within a parent structure. (...) Apart from our advanced ability in human reasoning, we have the same fundamental sentience possessed by other living creatures. Beyond that limit of awareness, the Universe in its native form is immaculately nonordered. We examine the dimensional relationship between quantum and classical frameworks to justify the theory. Mathematics requires operational consistency across its elements. In contrast, the Universe incorporates a feature of inconsistency in its native form. The companion paper to this document examines in detail how complexity develops from a null condition across dimensional levels. The argument’s foundation applies a general framework of stationary action and self-organization principles to the theory and experimental data on Hardy’s paradox. The complementary format to the dichotomy of paradoxical elements is its sliding scale of uncertainty between their extremes. The argument extends that the root source of societal biases, conflicts, and bigotries is the fundamental and systemic mechanism of paradox. (shrink)

We review several no-go theorems attributed to Gisin and Hardy, Conway and Kochen purporting the impossibility of Lorentz-invariant deterministic hidden-variable model for explaining quantum nonlocality. Those theorems claim that the only known solution to escape the conclusions is either to accept a preferred reference frame or to abandon the hidden-variable program altogether. Here we present a different alternative based on a foliation dependent framework adapted to deterministic hidden variables. We analyse the impact of such an approach on Bohmian mechanics (...) and show that retrocausation necessarily comes out without time-loop paradox. (shrink)

A classical probabilistics explanation for a typical quantum effect in Hardy's paradox is demonstrated.

Quantum mechanical weak values of projection operators have been used to answer which-way questions, e.g. to trace which arms in a multiple Mach–Zehnder setup a particle may have traversed from a given initial to a prescribed final state. I show that this procedure might lead to logical inconsistencies in the sense that different methods used to answer composite questions, like “Has the particle traversed the way X or the way Y?”, may result in different answers depending on which methods are (...) used to find the answer. I illustrate the problem by considering some examples: the “quantum pigeonhole” framework of Aharonov et al., the three-box problem, and Hardy’s paradox. To prepare the ground for my main conclusion on the incompatibility in certain cases of weak values and logic, I study the corresponding situation for strong/projective measurements. In this case, no logical inconsistencies occur provided one is always careful in specifying exactly to which ensemble or sample space one refers. My results cast doubts on the utility of quantum weak values in treating cases like the examples mentioned. (shrink)

During his encounter with Lethaeus Amor in theRemedia amoris, in which he discusses techniques to forget a former lover, Ovid writes the following:quisquis amas, loca sola nocent: loca sola caveto;quo fugis? in populo tutior esse potes.non tibi secretis est opus; auxilio turba futura tibi est.tristis eris, si solus eris, dominaeque relictaeante oculos facies stabit, ut ipsa, tuos.This passage has been discussed in Hardie's treatment of Lethaeus Amor, and, while he directly addresses Ovid's use oflociin this passage as I shall below, (...) his focus is on the rich intertextuality – textual remembrances – within theRemediarather than the use oflociin thears memoriaeproper. Hardie points out numerous intertexts in theRemedia, using the character of Lethaeus Amor to highlight the paradox of a learned reader of love poetry being unable to forget the poetry he has read, despite this specific oblivion being a precondition for curing oneself of love. In this case, theloca solaOvid warns against are ‘topics of solitude’ which ‘conjure up for the experienced reader scenes of erotic despair’, thus calling to mind the lover's own lovelorn state.

Figure décisive et controversée de l'hégélianisme contemporain, repère pour tant de penseurs français d'avant et d'après-guerre au premier rang desquels Bataille, Lacan et Sartre, Alexandre Kojève apparaît avant tout comme un commentateur de la Phénoménologie de l'Esprit, dont la lecture est le fruit d'un croisement hardi d'heideggerianisme et de marxisme.

Cet ouvrage constitue donc la première analyse de fond du système philosophique de Kojève.

In lieu of an abstract, here is a brief excerpt of the content:The Role of Malebranche in Ernest Renan's Philosophical Development BENJAMIN ROUNTREE RENANHASBEENCALLEDwith some justification the "Malebranche du dix-neuvi~me si~cle." 1 In his praise of the seventeenth-century philosopher, Renan was unconciously inclined to call attention to the similarities between himself and Malebranche by pointing out qualities which they were apt to share. A thinker as sinuous as Renan was bound to appreciate the power of subtle reasoning in such a (...) work as the admirable Recherche de la V~rit6. In a certain sense Renan is even the heir of a spirit to which Malebranche gave fresh impetus. Like Malebranche, he inveighed against pedants, dilettantes, and idolators of antiquity; he turned his back on tradition to favor modem thought over ancient, and placed his faith in a world governed by knowledge and reason in which progress and human perfectibility promise man happiness. In his basic optimism, in his belief that man is capable of knowing truth, in his somewhat pantheistic mysticism, Renan joins hands with Malebranche across the eighteenth century. How well did Renan know Malebranche? What did he think of him? Did his opinion of him undergo any evolution? To find the answers to these questions one must go back to about 1840, when Renan, a.t seventeen, began his study of Malebranche. By the time he was twenty, Renan, under the guidance of M. Gosselin, who little suspected how great a contribution Malebranche would make to Renan's decision to leave the Church, was reading the philosopher with enthusiastic regularity. Indeed, the Oratorian had become "l'objet perp6tuel" of his reflections, he tells us. The speculative terminology of the Entretiens sur la M6taphysique and the M6ditations chrgtiennes echoed through his class compositions and notebooks. His ideas on the general action of Providence in the universe were already similar to those of this philosopher, who, "illustre" and "saint," soon became for him a kind of spiritual hero, a hero whose exemplary intellectual zeal drew Renan instinctively ever more deeply into the contemplative life, into.the fervent and determined quest for "Truth." This "penseur hardi" was destined to excite Renan's own paradoxical mind as "le plus beau r~veur et le plus terrible logicien" ever to exist.~ 1L.

Appleton, 1921), pp. 15-16; Jean Pommier, Renan (Paris: Perrin, 1923), p. 37; La Jeunesse clSricale d'Ernest Renan (Paris: Les Belles Lettres, 1933), p. 138; "Les Lectures de Renan au sSminaire,"La Revue d'histoire litt6raire de la France (1934), p. 93. [47] 48 HISTORY OF PHILOSOPHY For a moment Malebranche, like Pascal, even helped delay Renan's loss of faith. The attempt of a Christian to satisfy the intelligence through vigorous application of Cartesian rationalism to theology and science fascinated the young student in 1843 as he read the Conversations chr~tiennes and the Recherche de la Vdritd. He eagerly believed that reason leads one to knowledge of God, that the search for Truth is the search for God. Thus, equating the Diety to Truth and retaining his belief in a providence evident in immutable natural law, Renan continued to accept the Catholic dogma, the Bible and revealed truth in a "general sense," as he says in his Souvenirs. After Renan's first soul-shattering year of philosophy Malebranche still stood alongside Pascal and Bossuet as a model of piety, as a "grand esprit," a profound intelligence capable of remaining genuinely Christian, a powerful thinker "qui dit sa messe route sa vie." a He appeared as one solution to Renan's own growing spiritual problem, for Malebranche's example seemed a way of retaining intellectual independence without leaving the Church. Here was a priest, Renan thought, who, in a time of steadily increasing ecclesiastical authority, had been able to live "peacefully" even as a member of a religious congregation without... (shrink)

Is the mathematical description of the Universe quantum, classical, both or neither? The mandated assumption of rationalism is that if an argument is inconsistent, it is flawed for a conclusion. However, suppose the structural basis of the Universe is fundamentally inconsistent. In that case, paradoxes in the frameworks of logic and mathematics would not be anomalies. A geometric model with a counter-rational framework of inconsistent relationships is applied to analyze Hardy’s paradox, the fine structure constant, and the general (...) relationship between the correlated quantum and classical EPR-type structures. The model conjectures that the well-studied paradoxes found in theoretical arguments and empirically in EPR phenomena are not anomalies and instead point to a new framework for modelling universal structures that incorporates inconsistency. (shrink)

A geometric model previously developed to analyze the quantum structure of Hardy’s paradox and explore the generic structure of universal states is applied to the Moebius band. The Moebius band’s conformity to the model strengthens its hypothesis. The claim made is that universal states cannot be represented as singular structures without reference to a partition of entangled parts that do not share property with each other. In other words, universal states categorically incorporate a systemic feature of inconsistency within (...) their frameworks. In logic and mathematics, this is the prohibition to forming theoretical principles that are singularly fundamental as absolute truths. The Moebius band contains a dualism of two categorically separate formats. It has, firstly, two discrete and observable sides and secondly, a unitary path, in which the sides are entangled and indistinguishable. Quantum structures display a similar attribute of duality. However, unlike quantum structure, the Moebius band displays the full duality of its structure at the classical level. The geometric model demonstrates the common structural basis shared in the Moebius band and quantum structure. (shrink)

Predatory grooming is a form of abuse most familiar from high-profile cases of sexual misconduct, for example, the Nassar case at Michigan State. Predatory groomers target individuals in a systematic effort to lead them into relationships in which they are vulnerable to exploitation. This is an example of a broader form of epistemic misconduct that Leydon-Hardy describes as epistemic infringement, where this involves the contravention of social and epistemic norms in a way that undermines our epistemic agency. In this (...) chapter, Leydon-Hardy looks at the distinctive epistemic harm caused by epistemic infringement. She argues that this harm cannot be understood simply as the victim’s having a false belief, or even as her being alienated from her belief-forming mechanisms. A deeper understanding of the harm caused by infringement shows that it stems from damage to one’s epistemic agency, and indeed, to one’s personhood. (shrink)

Aristotle maintains that every man has, or should have, a single end, a target at which he aims. The doctrine is stated in E.N. I 2. ‘If, then, there is some end of the things we do which we desire for its own sake, and if we do not choose everything for the sake of something else, clearly this must be the good and the chief good. Will not the knowledge of it, then, have a great influence on life? Shall (...) we not, like archers who have a mark to aim t, be more likely to hit upon what is right?’. Aristotle does not here prove, nor need we understand him as claiming to prove, that there is only one end which is desired for itself. He points out correctly that, if there are objects which are desired but not desired for themselves, there must be some object which is desired for itself. The passage further suggests that, if there were one such object and one only, this fact would be important and helpful for the conduct of life. (shrink)

He was almost immediately afterwards dismissed from his Lectureship at Trinity College, Cambridge, by the College Council.

It is sometimes thought that the renowned essayist Isaiah Berlin was incapable of writing a big book. But in fact he developed some of his most important essays--including "Two Concepts of Liberty" and "Historical Inevitability"--from a book-length manuscript that he intended to publish but later set aside. Published here for the first time, Political Ideas in the Romantic Age is the only book in which Berlin lays out in one continuous account most of his key insights about the history of (...) ideas in the period that he made his own--the Romantic age. Distilling his formative early work in the history of ideas, the book also contains much that is not found elsewhere in his writings. The last of Berlin's posthumous books, it is of great interest both for his treatment of the subject and for what it reveals about his intellectual development. Written for a series of lectures at Bryn Mawr College in 1952, and heavily revised and expanded by Berlin afterward, the book argues that the political ideas of the Romantic age are still largely our own--down to the language and metaphors they are expressed in. Vividly expounding the central political ideas of leading European thinkers in the period 1760-1830, including Helvetius, Condorcet, Rousseau, Saint-Simon, Hegel, Schelling, and Fichte, the book is written in Berlin's characteristically accessible style. The book has been carefully prepared by Berlin's longtime editor Henry Hardy, and Joshua L. Cherniss provides an illuminating introduction that sets it in the context of Berlin's life and work.

One of the most dynamic areas of plant molecular biology is the investigation of the actions of three classes of herbicides: s‐triazines (atrazine, simazine), glyphosate, and sulfonylureas (chlorsulfuron, sulfometuron methyl) (Figure 1). The results of this work are expected to provide the first significant applications of plant biotechnology: directly, in the genetic engineering of crop plants resistant to specific herbicides and, indirectly, in providing a molecular basis for the rational design of new herbicides for specific biological targets.s‐Triazines affect photosynthesis by (...) inhibiting the binding of quinones to the chloroplast membrane QB protein. An s‐triazine resistant QB protein isolated from weeds in fields consistently treated with the herbicide has a serine in place of a glycine in this highly conserved protein. Glyphosate inhibits 5‐enolpyruvyl‐shikimate‐3‐phosphate synthase (EPSP synthase), an enzyme in the aromatic amino acid biosynthetic pathway. Mutagenized bacteria produce a resistant EPSP synthase with a substitution of serine for proline. Sulfonylureas inhibit the acetolactate synthase (ALS) of bacteria, yeast, and higher plants; this enzyme catalyzes the first step in the synthesis of branched chain amino acids. Resistant ALS has been found in bacteria, yeast and tobacco with a proline substituted by serine in yeast ALS. These findings provide a strong basis for developing projected plant biotechnology applications. (shrink)

In this paper I discuss Plato's conception of expertise as a part of the Platonic theory of a good, successful life (eudaimonia). In various Platonic dialogues, Socrates argues that the good life requires a certain kind of knowledge that guides all our good, beneficial actions: the “knowledge of the good and bad”, which is to be acquired by “questioning ourselves and examining our and others’ beliefs”. This knowledge encompasses the particular knowledge of how to recognize experts in a given technical (...) domain. The central element in Socrates’ account of an expert is what I call the truth-and-caring criterion: an expert has to make seeking the truth and avoiding (avoidable) error her supreme epistemic goal and she has to make caring for common goods the supreme goal of practising her expertise.

"The goal of philosophy is always the same, to assist men to understand themselves and thus to operate in the open, not wildly in the dark."--Isaiah BerlinThis volume of Isaiah Berlin's essays presents the sweep of his contributions to philosophy from his early participation in the debates surrounding logical positivism to his later work, which more evidently reflects his life-long interest in political theory, the history of ideas, and the philosophy of history. Here Berlin describes his view of the nature (...) of philosophy, and of its main task: to uncover the various models and presuppositions--the concepts and categories--that men bring to their existence and that help form that existence. Throughout, his writing is informed by his intense consciousness of the plurality of values, the nature of historical understanding, and of the fragility of human freedom in the face of rigid dogma.
