What kind of duty do we have to try to stop other people doing wrong? The question is intelligible in just about any culture, but few of them seek to answer it in a rigorous fashion. The most striking exception is found in the Islamic tradition, where 'commanding right' and 'forbidding wrong' is a central moral tenet already mentioned in the Koran. As an historian of Islam whose research has ranged widely over space and time, Michael Cook is well (...) placed to interpret this complex subject. His book represents the first sustained attempt to map the history of Islamic reflection on this obligation. It covers the origins of Muslim thinking about 'forbidding wrong', the relevant doctrinal developments over the centuries, and its significance in Sunni and Shi'ite thought today. In this way the book contributes to the understanding of Islamic thought, its relevance to contemporary Islamic politics and ideology, and raises fundamental questions for the comparative study of ethics.

A co-authored article with Roy T. Cook forthcoming in a special edition on the Caesar Problem of the journal Dialectica. We argue against the appeal to equivalence classes in resolving the Caesar Problem.
Michael Cook's classic study, Commanding Right and Forbidding Wrong in Islamic Thought (Cambridge, 2001), reflected upon the Islamic injunction to forbid wrongdoing. This book is a short, accessible survey of the same material. Using Islamic history to illustrate his argument, Cook unravels the complexities of the subject by demonstrating how the past informs the present. At the book's core is an important message about the values of Islamic traditions and their relevance in the modern world.
Logical pluralism is the view that there is more than one correct logic. In this article, I explore what logical pluralism is, and what it entails, by: (i) distinguishing clearly between relativism about a particular domain and pluralism about that domain; (ii) distinguishing between a number of forms logical pluralism might take; (iii) attempting to distinguish between those versions of pluralism that are clearly true and those that are might be controversial; and (iv) surveying three prominent attempts to argue for (...) logical pluralism and evaluating them along the criteria provided by (ii) and (iii).

In his recent collection of essays, Language, Truth and History (2005), Donald Davidson appears to endorse a philosophy of language which gives primary importance to the notion of the speaker’s communicative intentions, a perspective on language not too dissimilar from that of Paul Grice. If that is right, then this would mark a major shift from the formal semanticist approach articulated and defended by Davidson in his Inquiries into Truth and Interpretation (1984). In this paper, I argue that although there (...) are many similarities between these two thinkers, Davidson has not abandoned his earlier views on language. (shrink)
The scholars who defend or dispute moral relativism, the idea that a moral principle cannot be applied to people whose culture does not accept it, have concerned themselves with either the philosophical or anthropological aspects of relativism. This study, shows that in order to arrive at a definitive appraisal of moral relativism, it is necessary to understand and investigate both its anthropological and philosophical aspects. Carefully examining the arguments for and against moral relativism, Cook exposes not only that anthropologists (...) have failed in their attempt to support relativism with evidence of cultural differences, but that moral absolutists have been equally unsuccessful in their attempts to refute it. He argues that these conflicting positions are both guilty of an artificial and unrealistic view of morality and proposes a more subtle and complex account of morality. (shrink)
Truth values are, properly understood, merely proxies for the various relations that can hold between language and the world. Once truth values are understood in this way, consideration of the Liar paradox and the revenge problem shows that our language is indefinitely extensible, as is the class of truth values that statements of our language can take – in short, there is a proper class of such truth values. As a result, important and unexpected connections emerge between the semantic paradoxes (...) and the set-theoretic paradoxes. (shrink)
Theodor W. Adorno and Jürgen Habermas both champion the goal of a rational society. However, they differ significantly about what this society should look like and how best to achieve it. Exploring the premises shared by both critical theorists, along with their profound disagreements about social conditions today, this book defends Adorno against Habermas' influential criticisms of his account of Western society and prospects for achieving reasonable conditions of human life. The book begins with an overview of these critical theories (...) of Western society. Both Adorno and Habermas follow Georg Lukács when they argue that domination consists in the reifying extension of a calculating, rationalizing form of thought to all areas of human life. Their views about reification are discussed in the second chapter. In chapter three the author explores their conflicting accounts of the historical emergence and development of the type of rationality now prevalent in the West. Since Adorno and Habermas claim to have a critical purchase on reified social life, the critical leverage of their theories is assessed in chapter four. The final chapter deals with their opposing views about what a rational society would look like, as well as their claims about the prospects for establishing such a society. Adorno, Habermas and the Search for a Rational Society will be essential reading for students and researchers of critical theory, political theory and the work of Adorno and Habermas. (shrink)
Wittgenstein's Metaphysics offers a radical new interpretation of the fundamental ideas of Ludwig Wittgenstein. It takes issue with the conventional view that after 1930 Wittgenstein rejected the philosophy of the Tractatus and developed a wholly new conception of philosophy. By tracing the evolution of Wittgenstein's ideas Cook shows that they are neither as original nor as difficult as is often supposed. Wittgenstein was essentially an empiricist, and the difference between his early views (as set forth in the Tractatus) and (...) the later views (as expounded in the Philosophical Investigations) lies chiefly in the fact that after 1930 he replaced his version of reductionism with something subtler. Nevertheless, he ended where he began, as an empiricist armed with a theory of meaning. (shrink)
The No-No Paradox consists of a pair of statements, each of which ?says? the other is false. Roy Sorensen claims that the No-No Paradox provides an example of a true statement that has no truthmaker: Given the relevant instances of the T-schema, one of the two statements comprising the ?paradox? must be true (and the other false), but symmetry constraints prevent us from determining which, and thus prevent there being a truthmaker grounding the relevant assignment of truth values. Sorensen's view (...) is mistaken: situated within an appropriate background theory of truth, the statements comprising the No-No Paradox are genuinely paradoxical in the same sense as is the Liar (and thus, on Sorensen's view, must fail to have truth values). This result has consequences beyond Sorensen's semantic framework. In particular, the No-No Paradox, properly understood, is not only a new paradox, but also provides us with a new type of paradox, one which depends upon a general background theory of the truth predicate in a way that the Liar Paradox and similar constructions do not.

This provocative study exposes the ways in which Wittgenstein's philosophical views have been misunderstood, including the failure to recognize the reductionist character of Wittgenstein's work. Author John Cook provides well-documented proof that Wittgenstein did not hold views commonly attributed to him, arguing that Wittgenstein's later work was mistakenly seen as a development of G. E. Moore's philosophy--which Wittgenstein in fact vigorously attacked. He also points to an underestimation of Russell's influence on Wittgenstein's thinking. Cook goes on to show (...) how these misunderstandings have had grave consequences for philosophy at large, and proposes that a more subtle appreciation of linguistic philosophy can yield valuable results.

Wittgenstein made numerous pronouncements about philosophical method. But did he practice what he preached? Cook addresses this question by studying Wittgenstein’s treatment of the problem of other minds, tracing a line of argument that runs through his writings and lectures from the early 1930s to the 1950s. Cook finds that there is an inconsistency between Wittgenstein’s methodological advice and his actual practice. Instead of bringing words back from their metaphysical to their everyday use, he allows himself to use (...) uncritically words whose provenance is clearly metaphysical.

A technique for the bilateral activation of neural nets that leads to a functional asymmetry of two simulated ''cerebral hemispheres'' is described. The simulation is designed to perform object recognition, while exhibiting characteristics typical of human consciousness-specifically, the unitary nature of conscious attention, together with a dual awareness corresponding to the ''nucleus'' and ''fringe'' described by William James (1890). Sensory neural nets self-organize on the basis of five sensory features. The system is then taught arbitrary symbolic labels for a small (...) number of similar stimuli. Finally, the trained network is exposed to nonverbal stimuli for object recognition, leading to Gaussian activation of the ''sensory'' maps-with a peak at the location most closely related to the features of the external stimulus. ''Verbal'' maps are activated most strongly at the labeled location that lies closest to the peak on homologous sensory maps. On the verbal maps activation is characterized by both excitatory and inhibitory Gaussians (a Mexican hat), the parameters of which are determined by the relative locations of the verbal labels. Mutual homotopic inhibition across the ''corpus callosum'' then produces functional cerebral asymmetries, i.e., complementary activation of homologous ''association'' and ''frontal'' maps within a common focus of attention-a nucleus in the left hemisphere and a fringe in the right hemisphere. An object is recognized as corresponding to a known label when the total activation of both hemispheres (nucleus plus fringe) is strongest for that label. The functional dualities of the cerebral hemispheres are discussed in light of the nucleus/fringe asymmetry. (shrink)

This essay examines the language of the Heng Xian and suggests that the text purposefully plays with Ru-style rhetoric, particularly that associated with the “Heart Method” for self-cultivation. The playful rhetoric is reminiscent of writings collected in the Zhuangzi and the use of parables associated with fourth century BCE philosopher Hu Shi.
The following paper continues discussions within this journal about how the work of Delueze and Guattari can inform radical pedagogy. Building primarily on Noel Gough's 2004 paper, we take up the challenge to move towards a more creative form of 'becoming cyborg' in our teaching. In contrast to work that has focused on Deleuzian theories of the rhizome, we deploy Guattari's work on institutional schizoanalysis to explore the role of group creativity in radical pedagogy. The institutional therapies of Felix Guattari's (...) schizoanalytic practice in the 1950s and 1960s and, before him, the Francophone educationalist Celestin Freinet, who founded the Modern School Movement, are explored and used to illuminate examples of some of our own attempts to set the classroom up as a space for collective engagement. We conclude by exploring how this understanding of the class as subject group may be used to mobilise action and de-stabilise the coordinates of existing academic divisions of labour. (shrink)
Value creation has long been hailed as the major objective of business firms by many management researchers. Some authors state that a firm must create value for its shareholders; some insist that value must be created not just for shareholders but also for all stakeholders. However, most discussions of value creation do not address an important question: "For whom the value is created?" The purpose of this paper is to take a first step to fill this void and propose a (...) model of value creation along three dimensions: financial, nonfinancial, and time. It is hoped that the model will contribute to a better understanding of how strategic and operational decisions of managers may create value for some stakeholders while destroying it for others.

While there exist numerous applications of Kuhn's analysis of scientific revolutions to economics, there is yet to be an application to econometrics. The present paper addresses this via an analysis of the often-documented transition between the textbook and LSE methodologies witnessed in British time series econometrics. This exercise allows a number of issues to be raised. First, it will be questioned whether the observed transition in econometrics is an appropriate subject for analysis within the Kuhnian framework. This is the primary (...) concern of the paper. Second, the adoption of Kuhn's approach will allow the witnessed transition in econometric methodology to be viewed from a different perspective to that permitted by more conventional historical accounts. This is seen to lead a number of interesting conclusions. Third, implications of the present study for Kuhn's analysis will be discussed. (shrink)
A long tradition regards Robert Desgabets as a Cartesian empiricist. He says things that sound strikingly like Locke, and he argues against anti-empiricist reasoning in Descartes, Malebranche, and Arnauld. Moreover, throughout his writings he endorses the empiricist principle that nothing is in the intellect except what was previously in the senses. Since the Cartesians are generally supposed to be prototypical non -empiricists, Desgabets’s being a Cartesian empiricist would make him a particularly interesting specimen. In this paper, however, I challenge the (...) case for taking Desgabets to be an empiricist. (shrink)
IN an article on Rousseau’s annotations of a popular botany text, Henry Cheyron describes the Genevan philosopher as ‘ce botaniste me´juge´’. 3 The misapprehension of Rousseau’s botanical practice identiﬁed by Cheyron has its roots, I believe, in Rousseau’s own depiction of his botanising in the Reˆveries; in the ‘Septie`me promenade’ Rousseau selfconsciously portrays this study as socially isolated, lazy and lacking in direction: ‘La botanique est l’e´tude d’un oisif et paresseux solitaire... Il se prome`ne, il erre librement d’un objet a` (...) l’autre, il fait la revue de chaque ﬂeur avec inte´reˆt et curiosite´.’4 Neither does Rousseau disguise botany’s role for him as a ‘the´rapeutique improvise´e’; the therapeutic purpose has tended to obscure the rigour, application, time and knowledge that Rousseau put into his botanical studies so that no less a scholar than Jean Starobinski asserts: ‘Jean-Jacques herborise en collectionneur, et non pas en naturaliste. C’est pour lui une occupation, un amusement, plutoˆt qu’une ve´ritable action.’5 Finally, Rousseau fuels this misunderstanding.. (shrink)
E-learning has been widely utilized in medical education and suggested by some proponents to represent a fundamental advance in educational methodology. We challenge this conclusion by examining e-learning in the context of broader learning theories, specifically as they relate to instructional design and methods. Core tenets of educational design are applied to e-learning in a unified model for instructional design, and examples of e-learning technologies are examined in the context of medical education, with reflections on research questions generated by these (...) new modalities. Throughout, we argue that e-learning is a tool that, when designed appropriately, can be used to meet worthy educational goals. (shrink)
At various times in history, a single power finds itself, at least for its region and time, a 'sole remaining superpower'. This paper explores the parallels between Athens' superpower status at the end of the Persian War and the US's superpower status in the contemporary world. Athens mismanaged her situation in ways that precipitated her own demise in the Peloponnesian War. The question of what might be analogous to Athens' conduct in contemporary US policy is explored to serve as a (...) kind of 'cautionary tale' for modern US strategy. (shrink)
The integration of biomedical terminologies is indispensable to the process of information integration. When terminologies are linked merely through the alignment of their leaf terms, however, differences in context and ontological structure are ignored. Making use of the SNAP and SPAN ontologies, we show how three reference domain ontologies can be integrated at a higher level, through what we shall call the OBR framework (for: Ontology of Biomedical Reality). OBR is designed to facilitate inference across the boundaries of domain ontologies (...) in anatomy, physiology and pathology. (shrink)
Let H be a proof system for quantified propositional calculus (QPC). We define the Σ q j -witnessing problem for H to be: given a prenex Σ q j -formula A, an H-proof of A, and a truth assignment to the free variables in A, find a witness for the outermost existential quantifiers in A. We point out that the Σ q 1 -witnessing problems for the systems G * 1 and G 1 are complete for polynomial time and PLS (...) (polynomial local search), respectively. We introduce and study the systems G * 0 and G 0, in which cuts are restricted to quantifier-free formulas, and prove that the Σ q j -witnessing problem for each is complete for NC 1. Our proof involves proving a polynomial time version of Gentzen’s midsequent theorem for G * 0 and proving that G 0-proofs are TC 0-recognizable. We also introduce QPC systems for TC 0 and prove witnessing theorems for them. We introduce a finitely axiomatizable second-order system VNC 1 of bounded arithmetic which we prove isomorphic to Arai’s first order theory AID + Σ b 0 -CA for uniform NC 1. We describe simple translations of VNC 1 proofs of all bounded theorems to polynomial size families of G * 0 proofs. From this and the above theorem we get alternative proofs of the NC 1 witnessing theorems for VNC 1 and AID. (shrink)
The concept of reproductive health promises to play a crucial role in improving women's health and rights around the world. It was internationally endorsed by a United Nations conference in 1994, but remains controversial because of the challenge it presents to conservative agencies: it challenges policies of suppressing public discussion on human sexuality and regulating its private expressions. Reproductive Health and Human Rights is designed to equip healthcare providers and administrators to integrate ethical, legal, and human rights principles in protection (...) and promotion of reproductive health, and to inform lawyers and women's health advocates about aspects of medicine and healthcare systems that affect reproduction. Rebecca Cook, Bernard Dickens, and Mahmoud Fathalla, leading international authorities on reproductive medicine, human rights, medical law, and bioethics, integrate their disciplines to provide an accessible but comprehensive introduction to reproductive and sexual health. They analyse fifteen case-studies of recurrent problems, focusing particularly on resource-poor settings. Approaches to resolution are considered at clinical and health system levels. They also consider kinds of social change that would relieve the underlying conditions of reproductive health dilemmas. Supporting the explanatory chapters and case-studies are extensive resources of epidemiological data, human rights documents, and research materials and websites on reproductive and sexual health. In explaining ethics, law, and human rights to healthcare providers and administrators, and reproductive health to lawyers and women's health advocates, the authors explore and illustrate limitations and dysfunctions of prevailing health systems and their legal regulation, but also propose opportunities for reform. They draw on the values and principles of ethics and human rights recognized in national and international legal systems, to guide healthcare providers and administrators, lawyers, governments, and national and international agencies and legal tribunals. Reproductive Health and Human Rights will be an invaluable resource for all those working to improve services and legal protection for women around the world. -/- Updates to this book, and information on translations to French, Spanish, Portuguese, Chinese and Arabic are now available at www.law.utoronto.ca/faculty/cook/ReproductiveHealth.html.

Individuals with traumatic brain injury (TBI) exhibit deficits in executive control, which may impact their reasoning abilities. Analogical reasoning requires working memory and inhibitory abilities. In this study, we tested adolescents with moderate to severe TBI and typically-developing (TD) controls on a set of picture analogy problems. Three factors were varied: complexity (number of relations in the problems), distraction (distractor item present or absent), and animacy (living or non-living items in the problems). We found that TD adolescents performed significantly better (...) overall than TBI adolescents. There was also an age effect present in the TBI group where older participants performed better than younger ones. This age effect was not observed in the TD group. Performance was affected by complexity and distraction. Further, TBI participants exhibited lower performance with distractors present than TD participants. The reasoning deficits exhibited by the TBI participants were correlated with measures of executive function that required working memory updating, attention, and attentional screening. Using MRI-derived measures of cortical thickness, correlations were carried out between task accuracy and cortical thickness. The TD adolescents showed negative correlations between thickness and task accuracy in frontal and temporal regions consistent with cortical maturation in these regions. This study demonstrates that adolescent TBI results in impairments in analogical reasoning ability. Further, TBI youth have difficulty effectively screening out distraction, which may lead to failures in comprehension of the relations among items in visual scenes. Lastly, TBI youth fail to show robust cortical-behavior correlations as observed in TD individuals. (shrink)
Major Depressive Disorder (MDD) is marked by disturbances in brain functional connectivity. This connectivity is modulated by rhythmic oscillations of brain electrical activity, which enable coordinated functions across brain regions. Oscillatory activity plays a central role in regulating thinking and memory, mood, cerebral blood flow, and neurotransmitter levels, and restoration of normal oscillatory patterns is associated with effective treatment of MDD. Repetitive Transcranial Magnetic Stimulation (rTMS) is a robust treatment for MDD, but the mechanism of action (MOA) of its benefits (...) for mood disorders remains incompletely understood. Benefits of rTMS have been tied to enhanced neuroplasticity in specific brain pathways. We summarize here the evidence that rTMS entrains and resets thalamocortical oscillators, normalizes regulation and facilitates reemergence of intrinsic cerebral rhythms, and through this mechanism restores normal brain function. This entrainment and resetting may be a critical step in engendering neuroplastic changes and the antidepressant effects of rTMS. It may be possible to modify the method of rTMS administration to enhance this mechanism of action and achieve better antidepressant effectiveness. We propose that rTMS can be administered: 1) synchronized to a patient’s individual alpha rhythm (IAF), or synchronized rTMS (sTMS); 2) as a low magnetic field strength sinusoidal wave form; and, 3) broadly to multiple brain areas simultaneously. We present here the theory and evidence indicating that these modifications could enhance the therapeutic effectiveness of rTMS for the treatment of MDD. (shrink)
The main result established in this paper is the following: If the base normed spaceV of completely additive weights is a norm-determining subspace of the space of finitely additive weights V acting on the order unit space spanning the operational logic, thenV has the ε-Jordan-Hahn property iff V has the approximate Jordan-Hahn property. Several examples illustrating the theory are given.
This article examines the attempted reform of education within an emerging audit culture in Australia that has led to the implementation of a high-stakes testing regime known as NAPLAN. NAPLAN represents a machine of auditing, which creates and accounts for data that are used to measure, amongst other things, good teaching. In particular, we address the logics of a policy intervention that aims to improve the quality of education through returning ?good teaching?. Using Deleuze?s concepts of series, events, copies and (...) simulacra, we suggest that an attempt to return past commonsense logics of ?good teaching? as a result of NAPLAN is not possible. In an audit culture as exemplified by NAPLAN, ?good teaching? is being reconceptualized through those practices and becomes unrecognizable. Whilst policy claims to improved equity and quality are admirable, this article suggests that the simulacral change to logics of good teaching may actualize something very different. (shrink)
It is shown that the logical truth of instances of the T-schema is incompatible with the formal nature of logical truth. In particular, since the formality of logical truth entails that the set of logical truths is closed under substitution, the logical truth of T-schema instances entails that all sentences are logical truths.
It is sometimes suggested that impure sets are spatially co-located with their members (and hence are located in space). Sets, however, are in important respects like numbers. In particular, sets are connected to concepts in much the same manner as numbers are connected to concepts—in both cases, they are fundamentally abstracts of (or corresponding to) concepts. This parallel between the structure of sets and the structure of numbers suggests that the metaphysics of sets and the metaphysics of numbers should parallel (...) each other in relevant ways. This entails, in turn, that impure sets are not co-located with their members (nor are they located in space). (shrink)
