Cet article présente plusieurs machines dont l’existence est intimement liée aux pratiques ludiques. Il montre que ces objets s’inscrivent aussi bien dans la recherche en robotique et en intelligence artificielle que dans les pratiques artistiques contemporaines. Il s’intéresse en particulier à l’espace de jeu ouvert par l’interaction avec les machines et propose de considérer cet espace comme le lieu privilégié d’une forme d’expérimentation anthropologique.

In developmental psychopathology, differentiating between the coexistence and the clinical entity of two problem areas is of utmost importance. So far, logistic regression analysis has already provided helpful answers, as shown in studies on comorbidity of tic disorders. While the concept of bridging symptoms may be investigated adequately by both logistic regression and the network approach, the former (latent variable) seems to be of advantage with regard to the problems of multiple comorbidities and development.

Jonathan Vogel has recently argued that counterfactual reliabilism cannot account for higher‐level knowledge that one's belief is true, or not false. His particular argument for this claim is straightforward and valid. Interestingly, there is a parallel argument, based on an alternative but plausible reinterpretation of the main premise in Vogel's argument, which squares CR with higher‐level knowledge both that one's belief is true and that one's belief is not false. I argue that, while Vogel's argument reveals the incompatibility of CR (...) and knowledge of certain higher‐level propositions, it does not establish the general claim that CR is incompatible with knowledge that any of one's beliefs is true, or not false.

In this paper we discuss some questions proposed by Prof. Newton da Costa on the foundations of quasi-set theory. His main doubts concern the possibility of a reasonable semantical understanding of the theory, mainly due to the fact that identity and difference do not apply to some entities of the theory’s intended domain of discourse. According to him, the quantifiers employed in the theory, when understood in the usual way, rely on the assumption that identity applies to all entities in (...) the domain of discourse. Inspired by his provocation, we suggest that, using some ideas presented by da Costa himself in his seminars at UFSC and by one of us in some papers, these difficulties can be overcome both on a formal level and on an informal level, showing how quantification over items for which identity does not make sense can be understood without presupposing a semantics based on a ‘classical’ set theory.

Two entities are weakly discernible when an irreflexive and symmetric relation holds between them. That weak discernibility holds in quantum mechanics is fairly uncontroversial nowadays. The ontological consequences of weak discernibility, however, are far from clear. Part of the literature seems to imply that weak discernibility points to a definite metaphysics to quantum mechanics. In this paper we shall discuss the metaphysical contribution of weak discernibility to quantum mechanics and argue that, contrary to part of current literature, it does not (...) provide for a fully naturalistic determination of metaphysics. Underdetermination of the metaphysics still plagues the way of the naturalist. (shrink)

In this paper we propose to take seriously the claim that at least some kinds of paraconsistent negations are subcontrariety forming operators. We shall argue that from an intuitive point of view, by considering paraconsistent negations as formalizing that particular kind of opposition, one needs not worry with issues about the meaning of true contradictions and the like, given that “true contradictions” are not involved in these paraconsistent logics. Our strategy will consist in showing that, on the one hand, the (...) natural translation for subcontrariety in formal languages is not a contradiction in natural language, and on the other, translating alleged cases of contradiction in natural language to paraconsistent formal systems works only provided we transform them into a subcontrariety. Transforming contradictions into subcontrariety shall provide for an intuitive interpretation for paraconsistent negation, which we also discuss here. By putting all those pieces together, we hope a clearer sense of paraconsistency can be made, one which may liberate us from the need to tame contradictions. (shrink)

Recently, in the debate about the ontology of quantum mechanics some authors have defended the view that quantum particles are individuals in a primitive sense, so that individuality should be preferred over non-individuality (the alternative option). Primitive individuality involves two main claims: (1) every item is identical with itself and (2) it is distinct from every other item. Non-relativistic quantum mechanics is said to provide positive evidence for that position, since in every situation comprising multiple particles there is a well-defined (...) number of them to begin with, and so they must be distinct from each other. We argue that the link between a well-defined number of items and the relation of identity that is being claimed to hold is not imposed by quantum mechanics, but rather by a metaphysical view. Formal evidence is advanced in favor of the thesis that counting may be performed for items without identity (non-individuals), so that quantum mechanics needs not be viewed as endorsing an ontology of individuals.

In this paper, we critically discuss the idea of a ‘philosophical interpretation’ of paraconsistent logics. We do so by considering the epistemic approach to paraconsistency, by Carnielli and Rodrigues, according to which paraconsistent logics should be interpreted exclusively in terms of non-conclusive evidence, and also, by considering counter-arguments by Barrio and Barrio and Da Re, according to whom paraconsistent logics are not specially tied to any specific interpretation. We begin by presenting the positions involved, and by arguing that the debate (...) may be profitably understood in terms of the distinction between pure and applied logics. We argue that dialetheism is not an interpretation of paraconsistent logics, but rather a view on truth and negation which requires use of paraconsistent logics. Something similar may be said about the epistemic approach itself. The result is that there is nothing distinctive to be called a philosophical interpretation of paraconsistent logics, but rather what we have are distinct applications of paraconsistent logics. Arguments by Barrio and Barrio and Da Re may be then re-framed more effectively. (shrink)

ABSTRACTThe role of the image in the third part of Practice in Christianity suggests that Kierkegaard was inspired by Meister Eckhart’s and Johann Tauler’s account of detachment. I argue that Kierkegaard was not only indirectly influenced by Tauler through the works of the Pietistic writers, but also directly inspired by Tauler’s sermons. Particularly striking are similarities to a sermon that was included in the Tauler edition owned by Kierkegaard: the second sermon on the Feast of the Exaltation of the Cross. (...) A comparison of the texts shows how both Tauler and Kierkegaard criticize the mental images their contemporaries hold of Jesus Christ. Both stress the importance of existential kenosis, which they describe as Entbildung of the intellect and the will, and which is an essential part of following Christ in his abasement. Furthermore, they analyze inadequate attempts to imitate Christ in a similar manner. Even though Kierkegaard and Tauler differ with regard to the ontological implications of Entbildung, the ethical implications are the same: one should not retreat from the world, but rather turn to it with a selfless attitude.

Let L be a countable language, let I be an isomorphism-type of countable L-structures, and let a∈2ω. We say that I is a-strange if it contains a computable-from-a structure and its Scott rank is exactly ω1a. For all a, a-strange structures exist. Theorem : If C is a collection of ℵ1 isomorphism-types of countable structures, then for a Turing cone of a’s, no member of C is a-strange.

Artificial Intelligence (AI), especially of the machine learning (ML) variety, is used by health care organizations to assist with a number of tasks, including diagnosing patients and optimizing operational workflows. AI products already proliferate the health care market, with usage increasing as the technology matures. Although AI may potentially revolutionize health care, the use of AI in health settings also leads to risks ranging from violating patient privacy to implementing a biased algorithm. This chapter begins with a broad overview of (...) health care AI and how it is currently used. We then adopt a “lifecycle” approach to discussing issues with health care AI. We start by discussing the legal and ethical issues pertaining to how data to build AI are gathered in health care settings, focusing on privacy. Next, we turn to issues in algorithm development, especially algorithmic bias. We then discuss AI deployment to treat patients, focusing on informed consent. Finally, we will discuss existing oversight mechanisms for health AI in the United States: liability and regulation. (shrink)

Nesta resenha, apresentamos os tópicos centrais discutidos no livro 'Consciência e mecânica quântica', de Raoni W. Arroyo. Discutimos criticamente alguns dos argumentos centrais do livro, focando em particular na tentativa do autor de argumentar contra abordagens mpisticas da mecãnica quântica, e na distinção mais refinada entre realismo científico e naturalismo.

Non-reflexive logics are systems of logic in which the reflexive law of identity is restricted or violated. The most well-known of such systems are Schrödinger logics and quasi-set theory; both are related with the metaphysics of quantum mechanics, aiming at formalizing the idea that quantum entities are non-individuals. We argue in this paper that non-reflexive logics may be seen as attempting to characterize two metaphysically incompatible notions of non-individuals: (i) non-individuals as violating self-identity and (ii) non-individuals as indiscernible entities. The (...) problem is that any choice between these options brings difficult questions, making the understanding of non-individuals through the apparatus of non-reflexive logics rather implausible.

Demonstrating a relational, dialogic way of thinking and writing, this book offers an innovative perspective on the human potential for intersubjective engagement and on the nature of true encounter. The authors engage in creative, associative dialogues and trialogues inspired by psychoanalysis and Buddhism, poetry and religion, theory and case studies, academic and free styles of writing - each enriching the other. Reflecting on the essence of relating, they convey a flow between inner, private reveries and shared ones, and between individual (...) expressions of thought and evolvements of newly born thirds. Through this interdisciplinary, experimental setting, the authors explore the possibility to reach truths and meanings that each individual would not have achieved on their own. Offering new concepts and formulations that may nourish psychotherapists' thought and be usefully implemented in their practice, this book presents a pressingly unique and essential viewpoint for psychoanalysts and psychoanalytic psychotherapists in training and in practice.

Some ambiguities in the verb ‘to know’ are analyzed, and it is argued that “undefeatably justified true belief” is the meaning of most philosophical interest with respect to specifying truth conditions for ‘S knows that p’. Two general conditions for an adequate definition of ‘S knows that p’ are discussed. Then a proposal for a quasi-causal theory of knowledge is introduced and defended.
