Anosognosia is literally ‘unawareness of or failure to acknowledge one’s hemi- plegia or other disability’ (OED). Etymology would suggest the meaning ‘lack of knowledge of disease’ so that anosognosia would include any denial of impairment, such as denial of blindness (Anton’s syndrome). But Babinski, who introduced the term in 1914, applied it only to patients with hemiplegia who fail to acknowledge their paralysis. Most commonly, this is failure to acknowledge paralysis of the left side of the body following damage to (...) the right hemisphere of the brain. In this paper, we shall mainly be concerned with anosognosia for hemiplegia. But we shall also use the term ‘anosognosia’ in an inclusive way to encompass lack of knowledge or acknowledgement of any impairment. Indeed, in the construction ‘anosognosia for X’, X might even be anosognosia for some Y. (shrink)

INTRODUCTION: Capgras delusion is sometimes defined as believing that close relatives have been replaced by strangers. But such replacement beliefs also occur in response to encountering an acquaintance, or the voice of a familiar person, or a pet, or some personal possession. All five scenarios involve believing something familiar has been replaced by something unfamiliar. METHODS: We evaluate the proposal that these five kinds of delusional belief should count as subtypes of the same delusion. RESULTS: Personally familiar stimuli activate the (...) sympathetic nervous system (SNS) much more strongly than unfamiliar stimuli. In Capgras delusion, this difference is absent, prompting the delusional idea that a familiar person is actually a stranger. We suggest this absence of an effect of familiarity on SNS response will occur in all five scenarios and will prompt the idea that the familiar has been replaced by the unfamiliar. CONCLUSIONS: We propose that: (a) all five scenarios be referred to as subtypes of Capgras delusion; (b) in all five, ideas about replacement are prompted by weakness of SNS responses to familiar stimuli; (c) this is insufficient to generate delusion. For a delusional idea to become a belief, a second factor (impaired hypothesis evaluation) must also be present. (shrink)

Article copyright 2002. We provide a battery of examples of delusions against which theoretical accounts can be tested. Then we identify neuropsychological anomalies that could produce the unusual experiences that may lead, in turn, to the delusions in our battery. However, we argue against Maher's view that delusions are false beliefs that arise as normal responses to anomalous experiences. We propose, instead, that a second factor is required to account for the transition from unusual experience to delusional belief. The second (...) factor in the etiology of delusions can be described superficially as a loss of the ability to reject a candidate for belief on the grounds of its implausibility and its inconsistency with everything else that the patient knows, but we point out some problems that confront any attempt to say more about the nature of this second factor.

In this book, psychologists and philosophers describe and discuss a range of case studies of delusional beliefs, drawing out general lessons both for the cognitive architecture of the mind and for the notion of rationality, and exploring connections between the delusional beliefs that occur in schizophrenia and the flawed understanding of beliefs that is characteristic of autism.

The question posed by Dunn and Kirsner (D&K) is an instance of a more general one: What can we infer from data? One answer, if we are talking about logically valid deductive inference, is that we cannot infer theories from data. A theory is supposed to explain the data and so cannot be a mere summary of the data to be explained. The truth of an explanatory theory goes beyond the data and so is never logically guaranteed by the data. (...) This is not just a point about cognitive neuropsychology, or even about psychology in general. It is a familiar point about all science. (shrink)

INTRODUCTION: In accounts of the two-factor theory of delusional belief, the second factor in this theory has been referred to only in the most general terms, as a failure in the processes of hypothesis evaluation, with no attempt to characterise those processes in any detail. Coltheart and Davies attempted such a characterisation, proposing a detailed eight-step model of how unexpected observations lead to new beliefs based on the concept of abductive inference as introduced by Charles Sanders Peirce. METHODS: In this (...) paper, we apply that model to the explanation of various forms of delusional belief. RESULTS: We provide evidence that in cases of delusion there is a specific failure of the seventh step in our model: the step at which predictions from hypotheses are considered in the light of relevant evidence. CONCLUSIONS: In the two-factor theory of delusional belief, the second factor consists of a failure to reject hypotheses in the face of disconfirmatory evidence. (shrink)

People acquire new beliefs in various ways. One of the most important of these is that new beliefs are acquired as a response to experiencing events that one did not expect. This involves a form of inference distinct from both deductive and inductive inference: abductive inference. The concept of abduction is due to the American pragmatist philosopher C. S. Peirce. Davies and Coltheart elucidated what Peirce meant by abduction, and identified two problems in his otherwise promising account requiring solution if (...) that account were to become fully workable. Here we propose solutions to these problems and offer an explicit cognitive model of how people derive new beliefs from observations of unexpected events, based on Peirce's work and Sokolov's ideas about prediction error triggering new beliefs. We consider that this model casts light not only upon normal processes of belief formation but also upon the formation of delusional beliefs. (shrink)

O ensaio tentar realizar um exercício hermenêutico de explicitar os sentidos de tempo que surgem no poema O tempo o homem, do poeta paraense Max Martins. Neste ensaio, as premissas interpretativas partem sobretudo do pensamento do filósofo paraense Benedito Nunes, tendo, no horizonte a Ontologia fundamental de Martin Heidegger, mas também de outros pensadores, como Giorgio Agamben. Além disto, o horizonte hermenêutico deste ensaio alcança um dos poetas que marcaram determinantemente a poesia de Max Marins, que foi seu amigo (...) Mário Faustino. Assim, o problema central desta investigação ensaística é a busca por saber o sentido dos tempos Ampulheta, Era, hera e Hora. A hipótese é que o aporte hermenêutico fenomenológico desenvolvido por Benedito Nunes para a relação dialógica, de “transa”, entre poesia e filosofia, viabilizada pelo que chamou de “passagem para o poético” (Kehre), oferece a tese de que o poema de Max Martins é um poema sobre o próprio poetar e sobre a “aventura” enquanto “evento” (Ereignis) da Hora que o artista faz.

Introduction: Cotard delusion—the delusional belief “I am dead”—is named after the French psychiatrist who first described it: Jules Cotard (1880, 1882). Ramachandran and Blakeslee (1998) proposed that the idea “I am dead” comes to mind when a neuropathological condition has resulted in complete abolition of emotional responsivity to the world. The idea would arise as a putative explanation: if “I am dead” were true, there would be no emotional responsivity to the world. Methods: We scrutinised the literature on people who (...) expressed the delusional belief “I am dead”, looking for data on whether such patients are reported as entirely lacking in emotional responsivity. Results: In numerous cases, patients with Cotard delusion are described as experiencing emotions including anxiety, fear, guilt, distress, euphoria and worry. Conclusions: We conclude that complete absence of emotional responsivity cannot be what prompts the delusional idea that one is dead. We propose that, in at least some cases, the idea “I am dead” comes to mind in response to symptoms of depersonalisation or derealisation, often present in cases of Cotard delusion, and give examples of Cotard patients with abnormalities in various neural areas that could be responsible for the presence of such symptoms.

The work reported in this paper investigated the putative functional dependence of pragmatic language skills on general mind‐reading capacity by testing theory‐of‐mind abilities and understanding of non‐literal speech in patients with schizophrenia and in healthy controls. Patients showed difficulties with inferring mental states on a false‐belief picture‐sequencing task and with understanding metaphors and irony on a story‐comprehension task. These difficulties were independent of low verbal IQ and a more generalised problem inhibiting prepotent information. Understanding of metaphors and understanding of irony (...) made significant and independent contributions to discriminating patients from controls, suggesting that metaphor and irony make distinct pragmatic demands.

A suggestion for research on Rosenzweig and Viktor von Weizsacker, Franz Rosenzweig's Philosophical legacy: Levinas or Strauss?

Lighting upon Weber as a history student in the late 1950s led to all round engagement with his work to the present day, beginning with rationality and bureaucracy, passing through appreciation of his synoptic vision of modernity, and arguing for the continuing relevance of his rationalization thesis. This emphasis on Weber’s contribution to understanding the course of modernity led in the 1990s to pointing out that his approach to epochal shift provides the basis for understanding the global age. The ever-developing (...) nature of his thought can be further illustrated in his studies of China. (shrink)

Max Weber is presented as a fervent supporter of the US-American life-style, its love of freedom and capitalist competition. After his return from the United States he makes all efforts at Americanizing Germany and bridging the transatlantic divide that Germany has brought about by its cultivation of "Gemütlichkeit" and "Bildung".

In their article “Out of nowhere: thought insertion, ownership and context-integration”, Jean-Remy Martin & Elisabeth Pacherie criticize the standard approach to thought insertion. However, their criticism is based on a misunderstanding of what the standard approach actually claims. By clarifying the notions ‘sense of ownership’ and ‘sense of agency’, I show that Martin & Pacherie’s own approach can be construed as a refined version of the standard approach.

Wallace, Max 1215 - Magna Carta raises the principle of equality through a 'fair trial for all', leading to the notion of the rule of law. 1517 - Martin Luther posts a document on the front door of the Catholic Church in Wittenberg, Germany. It contains 95 theses attacking church indulgences. Luther later spreads his ideas through the newly invented printing press. It is the start of the Reformation.

If and the function is partial recursive, it is easily seen that A is recursive. In this paper, we weaken this hypothesis in various ways (and similarly for ``min'' in place of ``max'') and investigate what effect this has on the complexity of A. We discover a sharp contrast between retraceable and co-retraceable sets, and we characterize sets which are the union of a recursive set and a co-r.e., retraceable set. Most of our proofs are noneffective. Several open questions are (...) raised. (shrink)

This review of Martin Matuštík’s Jürgen Habermas: A Philosophical-Political Profile questions whether Matuštík’s description of theexistentialist dimensions of Habermas’s political theory is adequate to the internal differentiation of Habermas’s conception of a substantive ethical life. In doing so, it questions whether Habermas’ own theory adequately distinguishes between first-person singular and first-person plural ethical discourse. The review closes with a reflection on ethical self-reflection and the collective past, a theme that Matuštík’s book discusses under the theme of “anamnestic solidarity.”.

Upon Scheler’ s death in 1928, Martin Heidegger remarked that he was the most important force in philosophy at the time. Jose Ortega y Gasset called Scheler "the first man of the philosophical paradise." The Human Place in the Cosmos, the last of his works Scheler completed, is a pivotal piece in the development of his writing as a whole, marking a peculiar shift in his approach and thought. He had been asked to provide an initial sketch of his (...) much larger works on philosophical anthropology and metaphysics--works he was not able to complete because of his early demise. Frings' new translation of this key work allows us to read and understand Scheler's thought within current philosophical debates and interests. The book addresses two main questions: What is the human being? And what is the place of the human being in the universe? Scheler responds to these questions within contexts of said two projected much larger works but not without reference to scientific research. He covers various levels of being: inorganic reality, organic reality (including plant life and psychological life), all the way up to practical intelligence and the spiritual dimension of human beings, and touching upon the holy. Negotiating two intertwined levels of being, life-energy ("impulsion") and "spirit," this work marks not only a critical moment in the development of his own philosophy but also a significant contribution to the current discussions of continental and analytic philosophers on the nature of the person.

With a few notable exceptions formal semantics, as it originated from the seminal work of Richard Montague, Donald Davidson, Max Cresswell, David Lewis and others, in the late sixties and early seventies of the previous century, does not consider Wittgenstein as one of its ancestors. That honour is bestowed on Frege, Tarski, Carnap. And so it has been in later developments. Most introductions to the subject will refer to Frege and Tarski (Carnap less frequently) —in addition to the pioneers just (...) mentioned, of course— , and discuss the main elements of their work that helped shape formal semantics in some detail. But Wittgenstein is conspicuously absent whenever the history of the subject is mentioned (usually briefly, if at all). Of course, if one thinks of Wittgenstein’s later work, this is obvious: nothing, it seems, could be more antithetic to what formal semantics aims for and to how it pursues those aims than the views on meaning and language that Wittgenstein expounds in, e.g., Philosophical Investigations, with its insistence on particularity and diversity, and its rejection of explanation and formal modelling. But what about his earlier work, the Tractatus (henceforth )? At first sight, that seems much more congenial, as it develops a conception of language and meaning that is both general and uniform, explanatory.. (shrink)
