In this essay, Ian Hardy argues that a research process involving generalizing from professional educational practice can and should inform the work of educators, including academic researchers, policymakers, and practitioners, but that these generalizations need to be derived from, and in dialogue with, the complexity and specificity of actual practice, the myriad ways such practice might be understood, and a conception of practice as historically informed. In making this case, Hardy draws upon social theorist Raewyn Connell's concept of (...) "dirty theory," and he uses an example of teacher professional learning in a rural community in southeast Queensland, Australia, to show how Connell's notion of dirty theory might be applied to research professional educational practice. Hardy maintains that such an approach has the benefit of making historically informed, context-aware, and epistemologically sensitive generalizations available as resources for informing the work of researchers, policymakers, and practitioners. He concludes by providing examples of such generalizations as evidence of the potential of Connell's theory. (shrink)
Rather than providing a list of "how-tos" and "must dos," this volume is premised on the understanding that by learning more about the current conditions under which teachers and other educators work and learn, it is possible to understand, ...
In this paper I present three problems for Simmons' singularity theory of truth as he presents it in Universality and the Liar. I begin with a brief overview of the theory and then present the three problems I see for it. The first problem shows that the singularity theory is in conflict with our ordinary notion of truth. I present a set of sentences that the singularity theory evaluates differently than does our pretheoretic concept of truth. The second problem shows (...) that Simmons' theory is incomplete, in the sense that there are sentences of its object language of which it does not have the resources to evaluate. The third problem suggests that Simmons theory does not, contrary to the claim of the book, allow for semantic universality. I consider Simmons' extension of the singularity theory to accommodate truth-in-a-context and show that it is inconsistent with his basic theory. Specifically I present a sentence which diagonalizes out of the basic theory. (shrink)
We consider probability theories in general. In the first part of the paper, various constraints are imposed and classical probability and quantum theory are recovered as special cases. Quantum theory follows from a set of five reasonable axioms. The key axiom which gives us quantum theory rather than classical probability theory is the continuity axiom, which demands that there exists a continuous reversible transformation between any pair of pure states. In the second part of this paper, we consider in detail (...) how the measurement process works in both the classical and the quantum case. The key differences and similarities are elucidated. It is shown how measurement in the classical case can be given a simple ontological interpretation which is not open to us in the quantum case. On the other hand, it is shown that the measurement process can be treated mathematically in the same way in both theories even to the extent that the equations governing the state update after measurement are identical. The difference between the two cases is seen to be due not to something intrinsic to the measurement process itself but, rather, to the nature of the set of allowed states and, therefore, ultimately to the continuity axiom.

In Brazil, every study involving human beings is required to produce an informed consent form that must be signed by study participants: this is stated in Resolution 196/96. 1 Consent must be obtained through a specific structured process. Objective: To present the opinions of women regarding how the process of obtaining informed consent should be conducted when women are invited to participate in studies on contraceptive methods. Subjects and Methods: Eight focus groups were conducted, involving a total of 51 women (...) living in the metropolitan region of Campinas. The women involved in the study were either participating in a clinical trial in the area of women's health or had participated in such a trial in the previous 12 months. A thematic guide was used to conduct the focus group discussions; the discussions were recorded, transcribed and a thematic analysis performed. Results: In general, the person who invites a woman to participate in a study should be a member of the research team but not the principal investigator. Information relating to the study should be given orally and in writing, both individually and in the group setting. Study volunteers should be informed about, among other things, the risks, possible side effects and discomforts, including long-term effects. The use of audiovisual aids to provide information was suggested. Conclusion: The process for obtaining informed consent was seen as a means of establishing a relationship between the volunteers and the investigator/research team. The information that the study participants expected to be given coincides with the requirements established under Resolution 196/96. The use of audiovisual aids would improve understanding of the information provided. (shrink)
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.
In a recent paper [e-print quant-ph/0101012], Hardy has given a derivation of “quantum theory from five reasonable axioms.” Here we show that Hardy's first axiom, which identifies probability with limiting frequency in an ensemble, is not necessary for his derivation. By reformulating Hardy's assumptions, and modifying a part of his proof, in terms of Bayesian probabilities, we show that his work can be easily reconciled with a Bayesian interpretation of quantum probability.
http://dx.doi.org/10.5007/1808-1711.2008v12n2p121 O objetivo deste trabalho é discutir e desenvolver o diagnóstico que efetua van Fraassen (1987, p. 110) da lei de Hardy-Weinberg, de acordo coo qual esta: 1) não pode ser considerada uma lei a ser utilizada como un axioma da teoria genética de populações, pois é uma lei de equilíbrio que só vale sob certas condições especiais, 2) só determina uma subclasse de modelos, 3) sua generalização resulta vácua e 4) variantes complexas da lei podem ser deduzidas para (...) pressupostos mais realistas. A discussão e desenvolvimento deste diagnóstico será levada a cabo tomando como base noções propostas por outra das concepções semânticas afim daquela desenvolvida por van Fraassen, a saber: a concepção estruturalista das teorias, e uma reconstrução da genética clássica de populações no marco de uma tal metateoria, também apresentada neste trabalho.

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)

[Ian Rumfitt] Frege's logicism in the philosophy of arithmetic consisted, au fond, in the claim that in justifying basic arithmetical axioms a thinker need appeal only to methods and principles which he already needs to appeal in order to justify paradigmatically logical truths and paradigmatically logical forms of inference. Using ideas of Gentzen to spell out what these methods and principles might include, I sketch a strategy for vindicating this logicist claim for the special case of the arithmetic of the (...) finite cardinals. /// [Timothy Williamson]The paper defends the intelligibility of unrestricted quantification. For any natural number n, 'There are at least n individuals' is logically true, when the quantifier is unrestricted. In response to the objection that such sentences should not count as logically true because existence is contingent, it is argued by consideration of cross-world counting principles that in the relevant sense of 'exist' existence is not contingent. A tentative extension of the upward Löwenheim-Skolem theorem to proper classes is used to argue that a sound and complete axiomatization of the logic of unrestricted universal quantification results from adding all sentences of the form 'There are at least n individuals' as axioms to a standard axiomatization of the first-order predicate calculus.

This article explores the proposal offered by Ian Hacking for the distinction between natural and social sciences—a proposal that he has defined from the outset as complex and different from the traditional ones. Our objective is not only to present the path followed by Hacking's distinction, but also to determine if it constitutes a novelty or not. For this purpose, we deemed it necessary to briefly introduce the core notions Hacking uses to establish his strategic approach to (...) social sciences, under the assumption that they are less well known that the ones corresponding to his treatment of natural sciences. Key Words: Ian Hacking • natural sciences • social sciences • distinction. (shrink)
Representing and Reconstructing: A Hermeneutical Reply to Ian Hacking. Hacking published in 1983 Representing and Intervening which has provoked, particularly in the US, the so called realism/anti-realism debate which is still alive today. He lays claim to anti-realism for theory and to realism for the experiment. Following him, only that which can be used for manipulating something (e.g., the path of an electon) is realistic. H. Putnam is a severe critic of this dualism. In my paper I am (...) going to take the Hacking-Putnam controversy as a starting-point for the problem about the determination of the relation between theory and experiment in the natural sciences. I shall then follow M. Schlick's discussion of this problem and the current solution to the problem as offered by H. Pietschmann. The differing interpretation of Kant according to the three perspectives shall be the guideline for the argumentation. The goal of my argumentation is that theory and experiment do not live their own lives, that in experimenting one always continues traditional chains of action, and that natural science cannot be regarded independently of the life world it takes place in. This insight into the representing and reconstructing overturns in natural science, due to the necessity of human decisions, opens up their hermeneutical dimension. (shrink)
I use Ian Hacking's views to explore ways of classifying people, exploiting his distinction between indifferent kinds and interactive kinds, and his accounts of how we 'make up' people. The natural kind/essentialist approach to indifferent kinds is explored in some depth. I relate this to debates in psychiatry about the existence of mental illness, and to educational controversies about the credentials of learner classifications such as 'dyslexic'. Claims about the 'existence' of learning disabilities cannot be given a clear, simple (...) and unambiguous interpretation. In particular I show that science cannot deliver a definitive taxonomy of learner categories, and that this has important implications for teachers and policy makers. (shrink)
Thomas Hardy is notorious for persecuting his characters mercilessly with coincidences and untimely chance and luck. I suggest that this idiosyncrasy is his exploration of the problem of "moral luck" to confront the reader with such fundamental ethical questions as how to make moral judgments and attribute moral responsibility.Making moral judgments is an essential part in our life, and our moral thoughts and beliefs invariably find expression mainly in the form of judgments. When we make moral judgments we are (...) applying moral concepts to ourselves and others to make sense of our lives, to provide a common ground for interpersonal moral communication and to enable our moral growth. Making such judgments is also an .. (shrink)
In Of Apes and Ancestors, Ian Hesketh attempts to de-mythologize the famous Oxford debate between Samuel Wilberforce, the bishop of Oxford, and Charles Darwin’s friends, Thomas Huxley and Joseph Hooker. Hooker and Huxley clashed publicly with Wilberforce at a meeting of the British Association for the Advancement of Science (BAAS) in June of 1860. At issue was the scientific content and general implication of Darwin’s Origin of Species. Hesketh argues that this event is best understood as a minor episode in (...) a complex web of personal and professional rivalries between two generations of naturalists. He further argues that Huxley aggressively reinterpreted the actual events of the debate for years afterwards, turning them into a “Galileo moment” for the nineteenth century, a moment in which science bravely stood up to religious authority and refused to back down. While his treatment of the debate and its context is well supported, the connection Hesketh draws between Huxley’s narrative and modern historiography is somewhat tenuous. (shrink)
This paper examines Ian Hacking's arguments in favor of entity realism. It shows that his examples from science do not support his realism. Furthermore, his proposed criterion of experimental use is neither sufficient nor necessary for conferring a privileged status on his preferred unobservables. Nonetheless his insight is genuine; it may be most profitably seen as part of a more general effort to create a space for a new form of scientific and philosophical certainty, one that does not require foundations.
While Ludwik Fleck's Genesis and Development of a Scientific Fact is mainly concerned with social elements in science, a central argument depends on his case study of the development of a serum test for syphilis, the Wasserman Reaction, which Fleck argues was the product of skill and of laboratory practice, not a simple discovery. Ian Hacking interprets the creation of new phenomena in science very differently, arguing that it can seen as an argument for scientific realism. Hacking's argument shows that (...) Fleck's case study does not lead to the conclusion Fleck expects, and may solve one of the main problems in Fleck's work, how to define an objective element of knowledge. (shrink)
This article examines the ethical implications of Ian Mitroff's scholarly contribution to the study of Organizational Communication. Although Mitroff does not specifically ground his work in ethics, this article considers an ethic of choicemaking to be a significant interpretive key for understanding the contribution of his research. In addition, this article provides another conceptual key for understanding the considerable quantity of Mitroff's work by organizing it around three major themes: science, decision-making, and myth. The goal of this article is to (...) make explicit two conceptual keys to Mitroff's scholarship, an ethic of choice and a three-fold division of his work that exemplifies his commitment to maximizing choice in organizational settings.

Summary Ian Hunter's early work on the history of literature education and the emergence of English as school subject issued a bold challenge to traditional accounts that have in the main focused on English either as knowledge of a particular field or as ideology. The alternative proposal put forward by Hunter and supported by detailed historical analysis is that English exists as a series of historically contingent techniques and practices for shaping the self-managing capacities of children. The challenge for the (...) field is to advance this historical work and to examine possible implications for English teaching. (shrink)

L. Hardy has formulated an axiomatization program of quantum mechanics and generalized probability theories that has been quite influential. In this paper, properties of typical Hamiltonian dynamical systems are used to argue that there are applications of probability in physical theories of systems with dynamical complexity that require continuous spaces of pure states. Hardy’s axiomatization program does not deal with such theories. In particular Hardy’s fifth axiom does not differentiate between such applications of classical probability and quantum (...) probability. (shrink)
Summary What are the connections between Ian Hunter's specific criticisms of cultural studies and his more general criticisms of those strands of the humanities that take issue with instrumental reasoning? How are these connections informed by his assessments of the limitations, and the consequences, of the ?moment of theory?? What are the implications of his critique of anti-instrumental defences of the humanities for contemporary debates concerning the future trajectories of cultural studies? In exploring these questions I consider the continuities between (...) Hunter's initial criticisms of cultural studies and the broader contours of his subsequent engagements with contemporary diagnoses of the fading critical vocation of the humanities. While endorsing the general tenor of Hunter's remarks on these questions, I conclude by arguing the need for genealogies of cultural studies and of the humanities that cast their nets more widely than Hunter's primary focus on textual disciplines.

Summary Ian Hunter's essay pursues several lines of argument, one explicit and the others not. The first is that of an historian correcting the mistaken view among Kantian commentators that Kant's conception of international justice had displaced Vattel's as the dominant one in nineteenth- and twentieth-century international thought. The second, which is not acknowledged, is that of a philosopher entering a debate over the relative cogency of the two conceptions. To accomplish this unacknowledged philosophical task, Hunter exaggerates the importance of (...) Kant's metaphysics in his treatment of international justice and understates the element of raison d'état in Vattel's casuistical ethics. The subtext in both lines of argument is criticism, political rather than either historical or philosophical, of Kant's effort to articulate principles of international justice, together with implicit advocacy of Vattelian ethics as a corrective to Kantian ideology.

In a recent article Mark Ian Thomas Robson argues that there is a clear contradiction between the view that possible worlds are a part of God's nature and the theologically pivotal, but philosophically neglected, claim that God is perfectly beautiful. In this article I show that Robson's argument depends on several key assumptions that he fails to justify and as such that there is reason to doubt the soundness of his argument. I also demonstrate that if Robson's argument were sound (...) then this would be a problem for all classical theists and not just those who hold the possible worlds view. (shrink)
Today's educational environment forms the stage for a host of debates, many of which centre on the use of standardized assessment in the classroom. With this push towards standardization, less time is being devoted to incorporating ?experiential? knowledge, or that knowledge which comes from hands?on, travel, natural and other worldly experiences, into the learning environment. William Wordsworth and Thomas Hardy, two somewhat unlikely sources of educational insight, do have a pertinent message to add to this ongoing educational discussion. The (...) two authors, through their personal experiences and through their literary works, draw from and examine the roles of formal education and the functions of various facets of knowledge in education. They exemplify the importance of finding a balance between formal educational experiences and informal avenues of education. Both men remind society that without the incorporation of experiential knowledge into the educational experience, students cannot reach the full potential of their intellectual, emotional, spiritual and social growth. Through an examination of the lives and works of Wordsworth and Hardy, the importance of non?formal, non?standardized experiences is reasserted at a time when it is of utmost importance to evaluate the components that make up modern education.
