The “body image” is a putative mental representation of one’s own body, including structural and geometric details, as well as the more familiar visual and affective aspects. Very little research has investigated how we learn the structure of our own body, with most researchers emphasising the canonical visual representation of the body when we look at ourselves in a mirror. Here, we used non-visual self-touch in healthy participants to investigate the possibility that primary sensorimotor experience may influence cognitive representations of (...) one’s own body structure. Participants used the fingers of one hand , to touch the fingers of the other . A conflict between the experience of the active and passive hand was introduced by experimenter interleaving their fingers with the fingers of the participant’s passive hand. This led to the active hand experiencing that it touched more fingers than the passive hand felt it was being touched by. The effects on representation of body structure were assessed using an implicit measure based on Kinsbourne and Warrington’s ‘in-between task’. We found an underestimation of the number of fingers in the central part of the hand specifically linked to the experience of self-touch. This pattern of results corresponds to the experience of the passive hand, but not the active hand. Nevertheless, comparable reorganisation of fingers within the hand representation was found for both active and passive hands. We show that primary sensorimotor experience can modify the representation of body structure. This modification is driven by the passive experience of being touched, rather than by the active experience of touching. We believe this is the first experimental study of effects of self-touch on the mental representation of the body. (shrink)

The recent distinction between sense of agency and sense of body-ownership has attracted considerable empirical and theoretical interest. The respective contributions of central motor signals and peripheral afferent signals to these two varieties of body experience remain unknown. In the present review, we consider the methodological problems encountered in the empirical study of agency and body-ownership, and we then present a series of experiments that study the interplay between motor and sensory information. In particular, we focus on how multisensory signals (...) interact with body representations to generate the sense of body-ownership, and how the sense of agency modulates the sense of body-ownership. Finally, we consider the respective roles of efferent and afferent signals for the experience of one’s own body and actions, in relation to self-recognition and the recognition of other people’s actions. We suggest that the coherent experience of the body depends on the integration of efferent information with afferent information in action contexts. Overall, whereas afferent signals provide the distinctive content of one’s own body experience, efferent signals seem to structure the experience of one’s own body in an integrative and coherent way.

The perception of sensory effects generated by one’s own actions is typically attenuated compared to the same effects generated externally. However, it is unclear whether this specifically relates to self-generation. Recent studies showed that sensory attenuation mainly relies on action preparation, not actual action execution. Hence, an attenuation of sensory effects generated by another person might occur if these actions can be anticipated and thus be prepared for.Here, we compared the perceived loudness of sounds generated by one’s own actions and (...) actions of another person that either could or could not be anticipated. We found an attenuation of the perceived loudness for self- as compared to other-generated sounds. This difference was independent of whether the sound-eliciting actions of the other person could be anticipated or not. Thus, sensory attenuation seems to be specifically tied to self-generation instead of being a secondary effect of agent-independent preparation for an upcoming action. (shrink)

To what extent can we feel what someone else feels? Data from neuroscience suggest that empathy is supported by a simulation process, namely the neural activation of the same or similar regions that subserve the representation of specific states in the observer. However, expectations significantly modulate sensory input, including affective information. For example, expecting painful stimulation can decrease the neural signal and the subjective experience thereof. For an accurate representation of the other person’s state, such top-down processes would have to (...) be simulated as well. However, this is only partly possible, because expectations are usually acquired by learning. Therefore, it is important to be aware of possible misleading simulations that lead to misinterpretations of someone’s state. (shrink)

In 2002, Dvurečenskij extended Mundici’s equivalence between unital abelian l -groups and MV-algebras to the non-commutative case. We analyse the relationship to Bosbach’s cone algebras and clarify the rôle of the corresponding pair of L -algebras. As a consequence, it follows that one of the two L -algebra axioms can be dropped.

We continue the investigation of generalized Bosbach states that we began in Part I, restricting our research to the commutative case and treating further aspects related to these states. Part II is concerned with similarity convergences, continuity of states and the construction of the s-completion of a commutative residuated lattice, where s is a generalized Bosbach state.

"El nacimiento de la fenomenologí­a. Las Investigaciones Lógicas de Edmund Husserl a los cien años de su publicación" Husserl introdujo el término Fenomenologí­a en 1901, en el contexto de sus Investigaciones Lógicas y fue bajo esta denominación que comprenderí­a en lo suscesivo su propia reflexión. Husserl se convirtió con ello en el fundador de la Fenomenologí­a, cuyo desarrollo marco, gradualmente, a toda la filosofí­a más allá de las fronteras de su natal Alemania. Heidegger, Ingarden, Schí¼tz, Sartre, Merleau Ponty, Lévinas o (...) Ricoeur, por ejemplo, son autores cuya obra serí­a impensable sin la veta del pensamiento que abrió Husserl. A partir de este texto, los esfuerzos de Husserl habrán de orientarse en dirección de una nueva fundamen-tación de la lógica pura y de la teorí­a del conocimiento. "The birth of the Phenomenology. The Edmund' Husserl"™s Logical Investigations at the hundred years of their publication." Husserl introduced the term Phenomenology in 1901, in the context of his Logical Investigations and it was under this denomination what he would understand in his latest reflection. Husserl became, with this conceptualization, the founder of the Phenomenology whose development mark, gradually, the whole philosophy beyond the frontiers of his native Germany. Heidegger, Ingarden, Schiitz. Sartre. Merleau Ponty, Levinas or Ricoeur, for example, are authors whose work would be imposible without the ground of the thought that Husserl opened up. Starting from this text, the efforts of Husserl had being guided in address of a new foundation of the pure logic and of the theory of the knowledge. (shrink)

BACKGROUND: Hallucinations and delusions that complicate Parkinson’s disease could lead to nursing home placement and are linked to increased mortality. Cognitive impairments are typically associated with the presence of hallucinations but there are no data regarding whether such a relationship exists with delusions. OBJECTIVE: We hypothesized that hallucinations would be associated with executive and visuospatial disturbance. An exploratory examination of cognitive correlates of delusions was also completed to address the question of whether they differ from hallucinations. METHODS: 144 PD subjects (...) completed a neuropsychological battery to assess cognition and the SAPS to examine psychosis. Correlational analyses assessed associations between hallucinations and delusions with cognitive domains. RESULTS: 48 subjects reported psychotic symptoms: 25 experienced hallucinations without delusions, 23 had symptoms dominated by delusions. Severity and/or number of hallucination subtypes were significantly correlated with lower scores in language, memory, attention, executive functioning, and visuospatial ability. Correlations with delusions were non-significant. Tests of differences in the size of the correlations between groups revealed a significant relationship between language and visuospatial performance with hallucinations. CONCLUSIONS: Cognitive correlates of hallucinations and delusions appear to be different in PD, suggesting distinct pathogenic mechanisms and possibly anatomical substrates. Hence, delusions may not share the same associations with dementia as hallucinations. Since this is a new finding, further studies will be needed to confirm our results. (shrink)

Questions of patient autonomy have formed an important part of ethical debate in medicine from at least the post-war period onwards. Although initially important as a counterweight to widespread medical paternalism, recent years have seen a reaction against a widely perceived ‘triumph of autonomy’. In particular, competent patients' refusal of life-saving or clearly beneficial treatment presents complex dilemmas for both healthcare professionals and ethicists. Discussion of the mechanism provided by the Israel Patient's Rights Act of 1996 for ethics committees to (...) override refusal of treatment by such patients has provided several examples in which it seems an obligation to benefit the patient can outweigh concerns regarding respect for their autonomy. However, such analyses as have been undertaken so far may be seen to omit important elements of the moral decision-making process that takes place even when the latter appears to ‘win out’. In addition to helping better prepare clinicians to meet such challenges in the future, a fuller appreciation of those elements that are present in justified cases of coercive treatment may enable them to arrive at a better understanding of what autonomy itself can mean in a medical context.

Scholarship on the Euthydemus has largely focused on the protreptic character of the Euthydemus—that is, the manner by which Socrates attempts to turn the young Cleinias toward philosophy. By focusing on the dramatic structure of the text, and above all its comic tenor, this article argues that it is Crito—he to whom Socrates tells his hilarious story of his encounter with the two sophist-brothers—who is the real object of Socrates’s protreptic speech.

Hegel’s basic position so far on the various meanings of evil as necessary and thereby intelligible directly in the development of spirit might be summed up as follows. Evil is always a necessary moment of instability which gives impetus in the movement from various meanings of particularity to various meanings of universality; from the more abstract expression of potential unity and truth to the more actualized notion and unity.

The period from Kant to Hegel is one of the most intense and rigorous in modern philosophy. The central problem at the heart of it was the development of a new standard of theoretical reflection and of the principle of rationality itself. The essays in this volume, published in 2000, consider both the development of Kant's system of transcendental idealism in the three Critiques, the Metaphysical Foundations of Natural Science, and the Opus Postumum, as well as the reception and transformation (...) of that idealism in the work of Fichte, Schelling and Hegel.

Consideration of the work of Sade in relation to Adorno usually refers to the much-discussed chapter from Dialektik der Aufklärung. But Adorno made a number of other remarks across his career that suggest a very different reading. I will discuss the three most significant of these remarks and show how they develop an approach to the libidinal aspect of aesthetic experience that challenges our understanding of the relation of thought and language. In doing so, Sade’s works indicate an extraordinary liberation (...) of the dialectic of natural-history through a mimesis of desire, which is made apparent in what Sade’s texts literally present; in their contingency and also their facticity.

Health professionals do not always have the luxury of making “right” choices. This article introduces the “devil's choice” as a metaphor to describe medical choices that arise in circumstances where all the available options are both unwanted and perverse. Using the devil's choice, the paper criticizes the principle of double effect and provides a re-interpretation of the conventional legal and ethical account of symptom relief in palliative care.

This paper deals with the genesis, development, and impact of Military Keynesianism in the U.S. Its impact on the civilian sector is examined in terms of: geographical distribution of military spending, sectoral militarization, labor market and occupational distortion, the militarization of R & D, R & D's impact on American competitiveness in the international market, the parasitic role of the military contract system and the unethical and exploitative role of military contractors. This paper exarnines the issues related to disarmament and (...) economic conversion with special reference to bills pending before the Congress. The author suggests are definition of "national security" in tune with the INF Treaty and the end of cold-war ideology. (shrink)

This work is the first to demonstrate the differences and similarities between Plato's myths and the traditional kind of which he was critical. It also actively demonstrates the extent to which his own myths support or undermine the philosophical ideas of the dialogues in which they are set. It offers new arguments and criticism on point of detail concerning modern interpretations.
