As many as two million people in the United Kingdom repeatedly see people, animals, and objects that have no objective reality. Hallucinations on the border of sleep, dementing illnesses, delirium, eye disease, and schizophrenia account for 90% of these. The remainder have rarer disorders. We review existing models of recurrent complex visual hallucinations (RCVH) in the awake person, including cortical irritation, cortical hyperexcitability and cortical release, top-down activation, misperception, dream intrusion, and interactive models. We provide evidence that these can neither (...) fully account for the phenomenology of RCVH, nor for variations in the frequency of RCVH in different disorders. We propose a novel Perception and Attention Deficit (PAD) model for RCVH. A combination of impaired attentional binding and poor sensory activation of a correct proto-object, in conjunction with a relatively intact scene representation, bias perception to allow the intrusion of a hallucinatory proto-object into a scene perception. Incorporation of this image into a context-specific hallucinatory scene representation accounts for repetitive hallucinations. We suggest that these impairments are underpinned by disturbances in a lateral frontal cortex–ventral visual stream system. We show how the frequency of RCVH in different diseases is related to the coexistence of attentional and visual perceptual impairments; how attentional and perceptual processes can account for their phenomenology; and that diseases and other states with high rates of RCVH have cholinergic dysfunction in both frontal cortex and the ventral visual stream. Several tests of the model are indicated, together with a number of treatment options that it generates. Key Words: Blindness; Charles Bonnet; cholinergic; cortical release; delirium; dementia; dream intrusion; hallucination; Perception and Attention Deficit (PAD) model; schizophrenia. (shrink)
Commentators agree that the Perception and Attention Deficit (PAD) model is a promising model for accounting for recurrent complex visual hallucinations (RCVH) across several disorders, though with varying detailed criticisms. Its central tenets are not modified, but further consideration of generative models of visual processing and the relationship of proto-objects and memory systems allows the PAD model to deal with variations in phenomenology. The commentaries suggest new ways to generate evidence that will test the model.
The analytical notion of ‘scientific style of reasoning’, introduced by Ian Hacking in the middle of the 1980s, has become widespread in the literature of the history and philosophy of science. However, scholars have rarely made explicit the philosophical assumptions and the research objectives underlying the notion of style: what are its philosophical roots? How does the notion of style fit into the area of research of historical epistemology? What does a comparison between Hacking’s project on styles of thinking and (...) other similar projects suggest? My aim in this paper is to answer these questions. Hacking has denied that his project of styles of thinking falls into the field of historical epistemology. I shall challenge his remark by tracing out the connections of the notion of style with historical epistemology and, more in general, with a tradition of thought born in France in the beginning of twentieth-century.

Ian Rumfitt has proposed systems of bilateral logic for primitive speech acts of assertion and denial, with the purpose of ‘exploring the possibility of specifying the classically intended senses for the connectives in terms of their deductive use’ : 810f). Rumfitt formalises two systems of bilateral logic and gives two arguments for their classical nature. I assess both arguments and conclude that only one system satisfies the meaning-theoretical requirements Rumfitt imposes in his arguments. I then formalise an intuitionist system of (...) bilateral logic which also meets those requirements. Thus Rumfitt cannot claim that only classical bilateral rules of inference succeed in imparting a coherent sense onto the connectives. My system can be extended to classical logic by adding the intuitionistically unacceptable half of a structural rule Rumfitt uses to codify the relation between assertion and denial. Thus there is a clear sense in which, in the bilateral framework, the difference between classicism and intuitionism is not one of the rules of inference governing negation, but rather one of the relation between assertion and denial.

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)
In his book The Boundary Stones of Thought, Ian Rumfitt considers five arguments in favour of intuitionistic logic over classical logic. Two of these arguments are based on reflections concerning the meaning of statements in general, due to Michael Dummett and John McDowell. The remaining three are more specific, concerning statements about the infinite and the infinitesimal, statements involving vague terms, and statements about sets.Rumfitt is sympathetic to the premisses of many of these arguments, and takes some of them to (...) be effective challenges to Bivalence, the following principle: Each statement is either true or false.However, he argues that counterexamples to Bivalence do not immediately lead to counterexamples to Excluded Middle, and so do not immediately refute classical logic; here, Excluded Middle is taken to be the following principle: For each statement A, is true.Much...

The rosy dawn of my title refers to that optimistic time when the logical concept of a natural kind originated in Victorian England. The scholastic twilight refers to the present state of affairs. I devote more space to dawn than twilight, because one basic problem was there from the start, and by now those origins have been forgotten. Philosophers have learned many things about classification from the tradition of natural kinds. But now it is in disarray and is unlikely to (...) be put back together again. My argument is less founded on objections to the numerous theories now in circulation, than on the sheer proliferation of incompatible views. There no longer exists what Bertrand Russell called ‘the doctrine of natural kinds’—one doctrine. Instead we have a slew of distinct analyses directed at unrelated projects. (shrink)
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.

. In my response to Ian Barbour's criticisms, I first argue for the anthropological dimensions and contextuality of any theology. Next I examine and criticize Barbour's thesis that I am an in‐compatibilist about divine action. Finally I illustrate the fact that I see genuine opportunities for a dialogue between theologians and scientists without apologetics, category mistakes, or relegating theology to the fringes of science, by pointing to evolutionary explanations of religion.
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)
In the Mead–Freeman controversy, Ian Jarvie has supported much of Derek Freeman’s critique of Margaret Mead’s Coming of Age in Samoa, arguing that Samoan society was sexually repressive rather than sexually permissive, that Mead was “hoaxed” about Samoan sexual conduct, that Mead was an “absolute” cultural determinist, that Samoa was a definitive case refuting Mead’s “absolute” cultural determinism, that Mead’s book changed the direction of cultural anthropology, and that Freeman’s personal conduct during the controversy was thoroughly professional. This article calls (...) into question these empirical and theoretical arguments, often using Freeman’s own field research and publications. (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.
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 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)
Charles Taylor's work has recently taken a religious turn, with Taylor becoming more explicit about his own religious faith and its influence on his thinking. Ian Fraser offers a systematic, critical exploration of the nature of Taylor's Catholicism as it appears in his writings. This reply to Fraser endorses his belief in the importance of looking carefully at Taylor's religious views. However, it raises doubts about some of Fraser's particular arguments and conclusions, and aims to foster a clearer understanding of (...) Taylor's religious beliefs. It poses questions for Fraser about what Taylor is setting out to do in A Catholic Modernity?; why he invokes the figure of Matteo Ricci; whether he believes that acts of practical benevolence are impossible without a religious foundation; and whether his religiously-inspired pluralism suffers an inherent contradiction.

This article reviews the research of “top rebirth scientist” Ian Stevenson on spontaneous past-life memory cases, focusing on three key problems with Stevenson’s work. First, his research of entirely anecdotal case reports contains a number of errors and omissions. Second, like other reincarnation researchers, Stevenson has done no controlled experimental work on such cases; yet only such research could ever resolve whether the correspondences found between a child’s statements and a deceased person’s life exceed what we might find by chance. (...) Finally, the best reincarnation research should at least meet the standards met by typical empirical research, but Stevenson’s methodology does not even meet the standards expected of third- or fourth-year college students. -/- 1.

Ian Hacking has defined himself as a philosopher in the analytic tradition. However, he has also recognized the profound influence that Michel Foucault had on much of his work. In this article I analyse the specific imprint of certain works by Foucault—in particular Les mots et les choses—in two of Hacking’s early works: Why Does Language Matter to Philosophy? and The Emergence of Probability. I propose that these texts not only share a debt of Foucauldian thought, but also are part (...) of what I believe is Hacking’s central project: the analysis of the historical and situated conditions of possibility for the emergence of concepts and of objects, inspired also by the French philosopher’s thought.

There is widespread acceptance in medical humanities circles that reading is good for doctors and that, in medical educational terms, it is particularly good at making better doctors by widening perspective and developing the sensibilities. Recent recommendations on medical education in the UK have allowed medical students to take courses in literature as a component of their degrees, and some have suggested that this option should be compulsory for all doctors. It is possible, however, that in our eagerness to assert (...) the primacy of a literary education for personal development, we can ignore other routes to enlightened, sensitive doctoring. This paper appraises the instrumental role of a literary education for doctors through an analysis of Ian McEwan’s novel Saturday, which deals with the dramatic events in the day in the life of a neurosurgeon.

. Using as a model contemporary analyses of scientific cognition, Ian Harbour has claimed that religious cognition is neither immediate nor inferential but has the structure of interpreted experience. Although I contend that Barbour has failed to establish his claim, I believe his views about the similarities between scientific and religious cognition are well founded. Thus on that basis I offer an alternative proposal that theistic religious cognition is essentially inferential and that religious experience is in fact the use of (...) inferentially acquired religious beliefs to interpret ordinary nonreligious experiences.

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)

How is a person's freedom related to his or her preferences? Liberal theorists of negative freedom have generally taken the view that the desire of a person to do or not do something is irrelevant to the question of whether he is free to do it. Supporters of the “pure negative” conception of freedom have advocated this view in its starkest form: they maintain that a person is unfree to Φ if and only if he is prevented from Φ-ing by (...) the conduct or dispositions of some other person. This definition of freedom is value-neutral in the sense that no reference is made to preferences over options or indeed to any other indicators of the values of options, either in the characterization of “Φ-ing” itself or in the characterization of the way in which Φ-ing can be constrained.

In the first part of chapter 2 of book II of the Physics Aristotle addresses the issue of the difference between mathematics and physics. In the course of his discussion he says some things about astronomy and the ‘ ‘ more physical branches of mathematics”. In this paper I discuss historical issues concerning the text, translation, and interpretation of the passage, focusing on two cruxes, the first reference to astronomy at 193b25–26 and the reference to the more physical branches at 194a7–8. In (...) section I, I criticize Ross’s interpretation of the passage and point out that his alteration of has no warrant in the Greek manuscripts. In the next three sections I treat three other interpretations, all of which depart from Ross's: in section II that of Simplicius, which I commend; in section III that of Thomas Aquinas, which is importantly influenced by a mistranslation of, and in section IV that of Ibn Rushd, which is based on an Arabic text corresponding to that printed by Ross. In the concluding section of the paper I describe the modern history of the Greek text of our passage and translations of it from the early twelfth century until the appearance of Ross's text in 1936.

A careful analysis of Harold Pinter’s screenplays, notably those written in the 1980s and early 1990s, renders an illustration of how the artist’s cinematic projects supplemented, and often heightened, the focus of his dramatic output, his resolute exploration of the workings of power, love and destruction at various levels of social interaction and bold revision of received values. It seems, however, that few of the scripts did so in such a subtle yet effective manner as Pinter’s intriguing fusion of the (...) erotic, violence and ethical concerns in the film The Comfort of Strangers, directed by Paul Schrader and based on Ian McEwan’s 1981 novel of the same name. The article centres upon Pinter’s creative adaptation of McEwan’s deeply allusive and disquieting text probing, amongst others, the intricacies and tensions of gender relations and sexual intimacy. It examines the screenplay-regarded by many critics as not merely an adaptation of the novel but another, very powerful work of art-addressing Pinter’s method as an adapter and highlighting the artist’s imaginative attempts at fostering a better appreciation of the connections between authoritarian impulses, love and justice. Similarly to a number of other Pinter filmscripts and plays of the 1980s and 1990s, the erotic and the lethal alarmingly intersect in this screenplay where the ostensibly innocent-an unmarried English couple on a holiday in Venice, who are manipulated, victimized and, ultimately, destroyed-are subtly depicted as partly complicit in their own fates.

There is, I gloomily suspect, little which is significantly new that remain to be said about psycho-analysis by philosophers. The almost profligate theorising that goes on within the psycho-analytic journals will, no doubt, continue unabated. It simply strikes me as unlikely that such theorising will generate further issues of the kind that excite the philosophical mind. Though in making such an observation, I recognise that I lay claim upon the future in a manner that many might believe to be unwise. (...) The place of psycho-analysis upon the intellectual map, the implications that psycho-analytic theory and practice have for the various kinds of judgements that we make about human behaviour, have been exhaustively discussed in recent times. Rather more specifically, whether psycho-analysis should be accorded the dignity of being labelled a ‘science’, what the significance is of psycho-analysis for those complex problems bounded by the notions of Reason, Freedom, Motivation, have occasioned much fruitful philosophical debate. It is not any wish of mine to add to the literature on these problems in the forlorn hope that even slightly different answers might be forthcoming. (shrink)
Post-war argumentation theorists have tended to regard argumentation as one thing and mathematical proof as another. Perelman (1958, 1969), for example, defined the word ‘argumentation’ stipulatively as a contrast term to ‘demonstration’: whereas mathematical reasoning as theorized by modern formal logic, he writes, is a matter of deducing theorems from axioms in accordance with stipulated rules of transformation, argumentation aims at gaining the adherence of minds (Perelman 1969, pp. 1–2). Toulmin (1958) contrasted his “jurisprudential model” of argument, according to which (...) the validity of an argument is a matter of its following proper procedure, with a “geometrical model” according to which validity is a matter of its having a proper shape comparable to the shape of a triangle (Toulmin 1958, p. 95).

From the time of its clearest origins with Pascal, the theory of probabilities seemed to offer means by which the study of human affairs might be reduced to the same kind of mathematical discipline that was already being achieved in the study of nature. Condorcet is to a great extent merely representative of the philosophers of the seventeenth and eighteenth centuries who were led on by the prospect of developing moral and political sciences on the pattern of the natural sciences, (...) specifically physics. The development of economics and the social sciences, from the eighteenth century onwards, may be said in part to have fulfilled and in a manner to have perpetuated these ambitions. In so far as the new sciences have been susceptible of mathematical treatment, this has not been confined to the calculus of probabilities. But there is a temptation at every stage to ascribe fundamental significance and universal applicability to each latest mathematical device that is strikingly useful or illuminating on its first introduction. It is the theory of games that enjoys this position at present, and shapes the common contemporary conception of the very same problems that preoccupied Condorcet. (shrink)
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)
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)
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.
