Although being generally safe, the use of Deep Brain Stimulation has been associated with a significant number of patients experiencing postoperative psychological and neurological harm within experimental trials. A proportion of these postoperative severe adverse effects have lead to the decision to medically prescribe device deactivation or removal. However, there is little debate in the literature as to what is in the patient’s best interest when device removal has been prescribed; in particular, what should be the conceptual approach to ethically (...) guide the decision to remove or maintain implants. The purpose of this article is to examine the ethical issues raised when patients refuse brain device explantation despite medical prescription. In order to illustrate these issues, we report and discuss a clinical case involving a patient suffering from treatment resistant depression who experienced forms of postoperative self-estrangement, as well as suicidal attempts, but who resists giving consent to device explantation.

Haeusermann et al. (Citation2023) draw three overall conclusions from their study on closed loop neuromodulation and self-perception in clinical treatment of refractory epilepsy. The first is that closed-loop neuromodulation devices did not substantially change epileptic patient’s personalities or self-perception postoperatively. The second is that some patients and caregivers attributed observed changes in personality and self-perception to the epilepsy itself and not to the DBS treatments. The third is that the devices provided participants with novel ways to make sense of their (...) illness. These findings further demonstrate a misalignment between some neuroethicists’ concerns about putative postoperative changes to personality, and the empirical evidence for such changes. Haeusermann et al. nonetheless concede that “neurotechnology directed at persisting rather than episodic clinical phenomena could have greater implications for personality or self-perception, either because they operate more continuously or are directed at clinical phenomena that are more stably integrated into patients’ self-concepts” (41). We acknowledge that the hypothesis that participants did not report changes because they were only episodically and not continually stimulated offers an interesting line for future investigation. Nonetheless, we would like to propose that potential postoperative personality changes might be correlated with the pathophysiology itself, rather than the stimulation effects of the technology. Generally, we advance the view that unintended effects solely induced by the technology cannot be excluded per se. Regardless, this comment aims to highlight that ethicists’ starting premise should be that patients suffering from diverse pathophysiology, or patients who are treated with stimulation in different brain regions and with differing parameters, would likely not react in the same way to treatment.

An argument opposing the unrestricted use of quantification in modal logic has been put forward by Quine. Central to this argument are the two phrases, The Morning Star, The Evening Star.One form of the argument is obtained by considering the following two statements: It is necessary that the Morning Star is identical with the Morning Star. It is not necessary that the Evening Star is identical with the Morning Star.

Postmortem evidence of chronic traumatic encephalopathy (CTE) in the brains of American National Football League players who suffered concussions while playing have intensified concerns about the risks of concussion in sport.1 Concussions are frequently sustained by amateur and professional players of Australia’s three most popular football codes (Australian football, rugby league, and rugby union) and, to a lesser extent, other contact sports such as soccer. This raises major concerns about possible long-term neurological damage, cognitive impairment and mental health problems in (...) players of these sports. (shrink)

The idea of creation as the free, spontaneous, and joyous play (līlā) of the gods has been a pervasive motif in Indian thought since Vedic times. In the tradition of Advaita Vedānta, however, where the sole Reality is Brahman alone, divine playfulness is given an illusionistic interpretation and līlā becomes an expression of the deceptive power of māyā.

In their article published in Nanoethics, “Ethical, Legal and Social Aspects of Brain-Implants Using Nano-Scale Materials and Techniques”, Berger et al. suggest that there may be a prima facie moral obligation to improve neuro implants with nanotechnology given their possible therapeutic advantages for patients [Nanoethics, 2:241–249]. Although we agree with Berger et al. that developments in nanomedicine hold the potential to render brain implant technologies less invasive and to better target neural stimulation to respond to brain impairments in the near (...) future, we argue against presenting the development of nanobionic clinical devices in terms of a moral obligation to conduct this research. In the first part of the paper, we consider what a duty to pursue new technologies might mean, and in the second we explore some of the negative consequences of defending such development as a moral obligation based on potential benefit. We argue that promoting the advances available to brain implants through developments in nanotechnology and bionics could contribute to medical rhetoric that indirectly increases the risk of exposing patients to harm when participating in clinical trials. We argue that rather than there being a moral obligation to improve nanobionics implants because of their potential benefit, the pursuit of improved neuro implants must be balanced against the prima facie obligations to protect patients against harm and to promote and protect patient autonomy.

Some writers have noted that valuation is often focused on foreseen changes. They say that we often don't value situations in terms of what we would have in them only but also in terms of the gains or losses that they offer us — that we then focus on departures from our status quo. They argue that such thinking conflicts with basic economic analysis, and also that it violates logic: they say that it is irrational. I agree that it seems (...) to be common. But is such a way of setting one's values a challenge to economics? And does it conflict with being rational? (shrink)

L’article met à jour un désaccord très peu connu entre les PP. Gaston Fessard (1897-1978) et Henri de Lubac (1896-1991), à propos du discernement à poser sur le communisme et le progressisme chrétien entre 1945 et 1950. Après avoir dégagé les deux périodes qui marquent l’histoire de ce différend – publication de France, prends garde de perdre ta liberté (1945-1946) aux éditions du Témoignage chrétien (I) ; conférence du P. de Lubac sur « La conception de l’homme » aux Semaines (...) Sociales de juillet 1947 (II) – l’auteur analyse les raisons du désaccord, en pointant notamment le fait que le P. Fessard avait développé une véritable méthode de discernement des événements et des idéologies, là où le P. de Lubac ne disposait pas d’instrument équivalent (III). (shrink)

Fengshui is a practice and skill whose origins go back to Chinese antiquity. It is about finding the best possible arrangement in space to position a grave or a habitation in such a way that human beings who have a link with that place might have success and happiness. The basic idea is that a good geomantic site will fill the distant ancestors with peace in their grave and that they will thus do everything to help their family. The text (...) deals with the history of fengshui, its methods as well as its conception of nature. (shrink)

According to Thagard and Stewart :1–33, 2011), creativity results from the combination of neural representations, and combination results from convolution, an operation on vectors defined in the holographic reduced representation framework. They use these ideas to understand creativity as it occurs in many domains, and in particular in science. We argue that, because of its algebraic properties, convolution alone is ill-suited to the role proposed by Thagard and Stewart. The semantic pointer concept allows us to see how we can apply (...) the full range of HRR operations while keeping the modal representations so central to Thagard and Stewart’s theory. By adding another combination operation and using semantic pointers as the combinatorial basis, this modified version overcomes the limitations of the original theory and perhaps helps us explain aspects of creativity not covered by the original theory. While a priori reasons cast doubts on the use of HRR operations with modal representations :5039–5054, 1987) such as semantic pointers, recent models point in the other direction, allowing us to be optimistic about the success of the revised version.

Cet article étudie la présence de la valeur humaniste de "douceur" chez Montaigne et Descartes, dans le champ de l'éducation, des relations humaines, mais aussi de la méthode cartésienne pour bien conduire son entendement. Ainsi, la méthode doit faire preuve de douceur dans la culture de l'âme, et Descartes dans l'Epître à Voet décrit la douceur comme une composante essentielle des "lois de l'amitié" entre les hommes. Il s'agit donc de proposer une interprétation nouvelle et humaniste de la pensée cartésienne, (...) qui porte à la fois sur la morale et la recherche de la vérité. (shrink)

According to several late medieval logicians, the use the universal quantifier ‘omnis’ creates the requirement that the sentence refers to at least three items—the principle of sufficientia appellatorum. The commitment is such that, when the quota is not fulfilled, one has to import the missing items from the realm of the nonexistent. While the central argument for this principle, whose origin is Aristotle’s De Caelo, stems from the contrast between unrestricted universal quantifiers and binary quantifiers, the discussion is often mixed (...) with another issue, concerning the requirement of a plurality of referents for universals. In this paper, we try to distinguish those different issues and map the reactions of xiii th authors to the principle of sufficientia appellatorum. (shrink)

Although the meaning of «phenomenology» significantly differs from Fichte to Henry, it is nonetheless a similar problem that both thinkers encounter since they both can be read as conceiving of the absolute as life, i.e. as that which essentially and necessarily escapes the power of the concept as well as that of sight. If life is according to its very essence invisible, then it must remain outside the realms of intuition and discourse. On the other hand, life is precisely what (...) a phenomenology of life as a philosophical discourse is aiming at. By placing the recognition of the absolute in the center of their approach, both Henry’s material phenomenology and Fichte’s phenomenology – presented in his 1804 Wissenschaftslehre Zweiter Vortrag – raise the question of the conditions of possibility enabling such knowing and recognition. From an ethical point of view, however, the decisive question, that of the existential form that this recognition could take in the realm of action, remains open. (shrink)

This is a translation from the Russian of Nikolai Lossky’s “Heдocтaтки гнoceoлoгiи Бepгcoнa и влiянie иxъ нa eгo мeтaфизикy” (The Defects of Bergson’s Epistemology and Their Consequences on His Metaphysics), which was published in the journal Boпpocы филocoфiи и пcиxoлoгiи (Questions of Philosophy and Psychology) in 1913. In this article, Lossky criticizes Bergson’s epistemological dualism, which completely separates intuition from reason, and which rejects reason in favor of intuition. For Bergson, reality is continuous, indivisible, fluid, etc., and reason distorts it (...) through its acts of division, abstraction, extraction, and so on. Lossky argues that this conclusion does not follow. Reason does not distort the living flow of reality; it rather provides a window unto aspects of the otherwise undivided seamless flowing organic whole. In fact, reason is itself a species of intuition in its own right, namely an intellectual intuition, the object of which is the atemporal facet of the world (the Platonic ideal realm), which is necessary for the existence of its temporal facet. Lossky thus challenges Bergson’s one-sided and self-defeating reduction of being to a flux of changes devoid of changing things. (Frédéric Tremblay). (shrink)

Clinical cases of frontal lobe lesions have been significantly associated with acquired aggressive behaviour. Restoring neuronal and cognitive faculties of aggressive individuals through invasive brain intervention raises ethical questions in general. However, more questions have to be addressed in cases where individuals refuse surgical treatment. The ethical desirability and permissibility of using intrusive surgical brain interventions for involuntary or voluntary treatment of acquired aggressiveness is highly questionable. This article engages with the description of acquired aggressiveness in general, and presents a (...) rare clinical case to illustrate the difficulties of treating this population. To expand the debate further, this article explores the ethics related to invasive brain surgery in three parts: a) it examines coercive involuntary invasive brain surgery for the benefit of protecting others on individuals suffering from acquired aggressiveness who lack decision-making capacities to consent; b) it addresses voluntary psychosurgery on individuals suffering from acquired aggressiveness who are competent to consent; and, c) it questions whether acquired aggressive individuals, who are legally competent, have a duty to consent to invasive brain surgery, in order to maintain their autonomy by reducing or even eliminate their aggressive drives. Ensuring the safety and efficacy of surgical brain interventions could increase the ethical permissibility of voluntary treatment, but it would not necessarily entail ethical justification for proceeding with invasive brain surgery for treatment of intractable acquired aggressive behaviour.

Si la forme est la condition de toute pensée et si la matière est informe, comment Plotin peut-il la penser ? Le recours à la négation accompagné d'une orientation du regard vers l'extériorité permet de faire signe vers l'informité de la matière ; cette négation cependant ne doit pas conduire à un nom vide, mais à un résidu ; l'image apparaît comme une aide qui évite l'évanouissement de la pensée dans le néant. Plotin développe en particulier l'image du miroir pour (...) donner à penser la matière ; comme elle, il est créateur d'illusions et impassible. Cependant, comme toute image, le miroir a ses limites pour illustrer le statut paradoxal de la matière. Proclus, lorsqu'il essaye de penser la participation, met en évidence ces limites : le miroir suppose l'extension, l'extraversion et l'altération de celui qui s'y mire. L'image ne demeure qu'une aide et doit donc rester subordonnée à la négation. If form is the condition of all thought and if matter has no form, how is it possible for Plotinus to think it ? Using negation and considering exteriority allows to lead to the formless nature of matter ; however, this negation must not lead up to an empty name, but to a residue ; the image appears as a help which saves thought from vanishing into nothingness. Plotinus uses especially the image of the mirror to help to think matter ; the mirror is, like matter, an illusion-maker and impassive. Nevertheless, like every image, the mirror has its limits to illustrate the paradoxical status of matter.Proclus, when he tries to think the participation, shows these limits : the mirror presupposes the expanse, extraversion and alteration of he who gazes at himself in it. The image is only a help and must be subordinated to negation. (shrink)

This paper is a tentative step toward formalizing in symbolic logic some of the central assumptions of Clark L. Hull's theory of behavior. There will be noticeable deviations from Hull's own terminology and form of statement, but this will be largely in the interest of greater logical simplicity. The notation of symbolic logic will not be used, but the behavioral axioms will be so stated as to admit of easy translation into such notation. Such easy translatability seems to be a (...) prerequisite if theorems are to be derivable with genuine deductive rigor. (shrink)

Affirmer « à chacun sa vérité », ce n’est pas s’enfermer dans le règne de l’opinion. Car la Vérité naît moins du dépassement de la diversité des points de vue que de leur compréhension intime et de leur articulation complexe. Plus que les philosophes, les écrivains semblent à même de rendre raison de cette vérité des vérités. En restituant le point de vue d’une foule de personnages, ils dévoilent la grande variété des perspectives sur le monde et permettent à leurs (...) lecteurs d’accéder à l’épaisseur cognitive feuilletée du sens commun. L’art du roman de Virginia Woolf est à cet égard exemplaire, comme le montrait dès 1951 le psychologue Maxime Chastaing dans La philosophie de Virginia Woolf. (shrink)
