Many neuroscientific experiments, based on monitoring brain activity, suggest that it is possible to predict the conscious intention/choice/decision of an agent before he himself knows that. Some neuroscientists and philosophers interpret the results of these experiments as showing that free will is an illusion, since it is the brain and not the conscious mind that intends/chooses/decides. Assuming that the methods and results of these experiments are reliable the question is if they really show that free will is an illusion. To (...) address this problem, I argue that first it is needed to answer three questions related to the relationship between conscious mind and brain: 1. Do brain events cause conscious events? 2. Do conscious events cause brain events? 3. Who is the agent, that is, who consciously intends/chooses/ decides, the conscious mind, the brain, or both? I answer these questions by arguing that the conscious mind is a property of the brain due to which the brain has the causal capacity to interact adaptively with its body, and trough the body, with the physical and sociocultural environment. In other words, the brain is the agent and the conscious mind, in its various forms - cognitive, volitional and emotional - and contents, is its guide of action. Based on this general view I argue that the experiments aforementioned do not show that free will is an illusion, and as a starting point for examining this problem I point out, from some exemplary situations, what I believe to be some of the necessary conditions for free will.Key-words: Agent brain, conscious mind, free will, Libet-style experiments.

I present and consider critically O'Regan and Noë's sensorimotor contingency theory, proposed as an alternative to solve the explanatory gap problem. I start with the criticism that these authors address the current conception of representation, according to which conscious experiences are representations of the external world produced by the brain. Afterward, I summarize the way the sensorimotor contingency theory addresses the problem of the explanatory gap, explaining the existence, form, and content of visual consciousness in terms of an "exploratory activity" (...) mediated by sensorimotor contingency laws. Finally, in agreement with criticisms addressed to O'Regan and Noë's solution, I propose a way to face the problem of the explanatory gap, which, recognizing the relevance of the body and the external environment to the existence, form and content of visual consciousness, but privileging the role of the brain as an organ of visual consciousness, and as an agent who uses visual consciousness as a guide to initiate and maintain embodied and situated adaptive actions in the world.

Alguns filósofos materialistas pensam, contra o dualismo de substância, que uma mente incorporada é apenas uma mente que depende de um corpo para existir, isto é, que a mente náo existe independentemente de um corpo. Tomarei como representativas deste ponto de vista muito limitado sobre incorporaçáo as idéias de Lynne Baker e sua Teoria da Constituiçáo de Propriedades. Baker diz que prefere enfrentar o problema da relaçáo pessoa e corpo em vez da relaçáo mente e corpo porque esta última formulaçáo (...) implica a idéia de uma mente distinta e separada do corpo enquanto que a primeira está mais de acordo com sua concepçáo de uma mente incorporada e situada. O problema é que Baker esquece isso quando define pessoa em termos de perspectiva de primeira pessoa ou autoconsciência. Embora Baker diga que a autoconsciência depende de condições estruturais – um corpo – e ambientais – a situaçáo -, o que torna a pessoa humana autoconsciente uma entidade ontologicamente distinta do corpo que a constitui e de outros animais sáo suas realizações tais como arte, filosofia, ciência, moral, etc. Parece que, para Baker, a autoconsciência é náo apenas uma condiçáo necessária mas também uma condiçáo suficiente para aquelas realizações humanas, enquanto que o corpo desempenha apenas um papel indireto. Contra tais idéias nós podemos perguntar: as grandes realizações que distinguem pessoas humanas de outros animais seriam possíveis independentemente da constituiçáo biológica de nosso corpo e de suas necessidades?

: Interpreting results of contemporary neuroscientif studies, I present a non-reductive physicalist account of mind-brain relationship from which the criticism of unintelligibility ascribed to the notion of mental causation is considered. Assuming that a paradigmatic criticism addressed to the notion of mental causation is that presented by Jaegwon Kim’s analysis on the theory of mind-body supervenience, I present his argument arguing that it encompasses a formulation of the problem of mental causation, which leads to difficulties by him pointed. To ask (...) "how mental events, being a non-physical property of the brain, could act causally on brain structure and functioning?", is not to treat the mind as a property of the brain, but as a Cartesian substance. I argue that, rather than asking "how does mind could act causally on the brain?", as if the mind were something apart and independent of the brain, it would be more in line with a non-reductive physicalist view to ask "how the brain, guided by its mind, could act causally on itself?". To justify this last formulation of the problem of mental causation, I propose a "double face view", which consists in considering the consciousness as the essential property of the mind, and mind and brain as inseparable, dependent and irreducible faces. It means, in general terms, that the conscious mind is the result of brain structure and activity - "conscious mind as brain" - and that the brain, using its conscious mind as a guide to its actions, interacts with its body, and with the physical and sociocultural environment, constructing and being constructed by both - "brain as conscious mind". Resumo: Interpretando resultados de estudos neurocientíficos contemporâneos, apresento, em linhas gerais, uma abordagem fisicalista não-reducionista da relação mente-cérebro, a partir da qual a crítica de ininteligibilidade atribuída à noção de causação mental é considerada. Assumindo que uma crítica paradigmática à noção de causação mental é aquela apresentada por Jaegwon Kim, em suas reflexões sobre a teoria da superveniência mente-corpo, considero criticamente o seu argumento, oferecendo uma concepção geral a respeito da relação mente-cérebro, a qual acredito tornar a noção de causação mental inteligível. Penso que o principal problema do argumento de Kim se relaciona à formulação da questão da causação mental por ele aceita. Por exemplo, ao perguntar "como os eventos mentais, sendo propriedades não-físicas do cérebro, podem agir causalmente sobre a estrutura e funcionamento do cérebro?" a mente está sendo considerada não como uma propriedade do cérebro, mas como uma substância cartesiana. Entendo que, em vez de perguntar "como a mente age causalmente sobre o cérebro?", como se a mente fosse algo dele separada e independente, seria mais conforme a uma concepção fisicalista não-reducionista perguntar "como o cérebro, guiado por sua mente, pode agir causalmente sobre si mesmo?" Para justificar essa formulação do problema da causação mental, proponho uma "abordagem dupla face" da relação mente-cérebro, segundo a qual a consciência é a propriedade essencial da mente, sendo a mente inseparável do cérebro, embora a ele irredutível, e a estrutura e funcionamento do cérebro dependente numa certa medida da existência da mente. Isso significa, em termos gerais, que a mente consciente resulta da estrutura e funcionamento do cérebro - "mente consciente como cérebro" -, e que o cérebro, usando a mente consciente como um guia para sua ação, interage com seu corpo e com o ambiente físico e sociocultural circundante, construindo e sendo construído por ambos - "cérebro como mente consciente".

Propomo-nos a mostrar que a intuição tal como aparece no pensamento de Bergson é tanto uma faculdade de conhecimento que se opõe à inteligência quanto um método filosófico constituído por procedimentos racionais, os quais a propiciam e enriquecem. Nesse sentido, ambos os aspectos da intuição estão intimamente ligados, sendo cada um imprescindível à compreensão do outro.

Recorrendo à noção de duração interior e ao modo de inserção da consciência no mundo, Bergson postula que, apesar de, não raro, (...) as ações serem determinadas, há uma liberdade essencial a partir da qual podem-se compreender os limites de qualquer ciência que tome como objeto a ação humana.

The question I have proposed to reflect on in this article is whether, and if so, in what terms, a non-reductionist and interactionist physicalist approach explains the relationship between consciousness and brain. For that, I took as a guiding thread the problem of the explanatory gap, which was faced with the problem of the ontological gap, which involves two intertwined issues: 1. Does the existence of an explanatory gap implies the existence of an ontological gap? 2. Does the nonexistence of (...) an ontological gap imply the nonexistence of an explanatory gap? I believe this reflection is welcome, since these two perspectives, the epistemological and the ontological, are often confused, and not understood. (shrink)

My aim is to show that the externalist theses, "meanings are not in the head" and "thoughts are not in the head", do not necessarily imply the more extreme thesis that "the mind is not in the head". I consider this question in terms of the social externalism approach of Tyler Burge and Lynne Baker, arguing that the importance these thinkers attribute to language in questions relative to the mind does not mean either the reduction of the mind to language (...) or the elimination of the mind. My conclusion is that social externalism is not an efficient strategy for dealing with problems of the nature of the mind or the relationship between mind and body.Meu objetivo é mostrar que as teses externalistas "os significados não estão na cabeça" e "os pensamentos não estão na cabeça" não implicam, necessariamente, a tese mais radical "a mente não está na cabeça".

Public decisions concerning large projects with detrimental environmental or heritage impacts involve value conflicts which stem from the diverse interests and variety of ways of evaluating the costs and benefits of such projects. They are also framed by institutionalised procedures and practices which favour certain concerns to the detriment of others. This paper aims to contribute towards a better understanding of how these procedures and practices, namely decision support tools such as the Environmental Impact Assessment (EIA), tend to shape public (...) decision-making processes in particular ways. It draws on a study of the public controversy surrounding the Foz Tua dam in Portugal, with a focus on the values upheld by the different parties in the controversy and their interplay in the production of justifications, specifically the actors’ positions on values and value conflicts and the restrictions posed by institutionalised public decision-making procedures on the expression and consideration of certain values.

El presente trabajo investiga las tesis sobre el poder civil de Alonso de la Veracruz que buscan incorporar en la comunidad política española a los habitantes autóctonos del Nuevo Mundo, tesis que suelen relacionarse con F. de Vitoria y el tomismo español, y que últimamente son consideradas parte del republicanismo novohispano elaborado desde la periferia americana. Se busca demostrar que su propósito era aplicar una teoría de derechos naturales, sin que ello implique participación política de los indios americanos. Se analiza (...) la postura del fraile frente a la diversidad cultural y la guerra contra los indios.

The article seeks to show that the purpose of such theses was to apply a theory of natural rights that did not entail the political participation of the indigenous population, as well as to analyze Veracruz's position regarding cultural diversity and the war against the indigenous peoples.

Is the procreation asymmetry intuitively supported? According to a recent article in this journal, an experimental study suggests the opposite. Dean Spears (2020) claims that nearly three-quarters of participants report that there is a reason to create a person just because that person’s life would be happy. In reply, I argue that various confounding factors render the study internally invalid. More generally, I show how one might come to adopt the procreation asymmetry for the wrong reasons by misinterpreting one’s intuitions.

This paper offers a unified explanation for the procreation asymmetry and the non-identity thesis – two of the most intractable puzzles in population ethics. According to the procreation asymmetry, there are moral reasons not to create lives that are not worth living but no moral reasons to create lives that are worth living. I explain the procreation asymmetry by arguing that there are moral reasons to prevent the bad, but no moral reasons to promote the good. Various explanations for the (...) procreation asymmetry have failed to explain the non-identity thesis: if one could create a person with a good life or a different person with a better life, one has a moral reason to create the better life. I argue that reflections on the misfortune of unfulfilled potential allow us to circumvent the non-identity problem. (shrink)

Este presente artigo visa buscar os pressupostos da dupla reflexão de Climacus para melhor compreender a sua crítica ao pensamento dialético-especulativo.

Is there a pro tanto moral reason to create a life merely because it would be good for the person living it? Proponents of the procreation asymmetry claim there is not. Defending this controversial no reason claim, some have suggested that it is well in line with other phenomena in the moral realm: there is no reason to give a promise merely because one would keep it, and there is no reason to procreate merely to increase the extent of justice (...) in the world. Allegedly, some analogs extend so far as to support a unified theory of the no reason claim and the nonidentity thesis, that is, the view that of two persons leading lives of positive wellbeing, there is a reason to create the person with higher wellbeing. I dismantle the proposed analogs and show that they fail to meet various desiderata. Moreover, I refute Johann Frick's argument that the no reason claim follows from the assumption that reasons of beneficence are reasons to act for the sake of people. By criticizing attractive defenses for the no reason claim, I weaken its plausibility. (shrink)

Cognitive representations are typically analysed in terms of content, vehicle and format. While current work on formats appeals to intuitions about external representations, such as words and maps, in this paper we develop a computational view of formats that does not rely on intuitions. In our view, formats are individuated by the computational profiles of vehicles, i.e., the set of constraints that fix the computational transformations vehicles can undergo. The resulting picture is strongly pluralistic, it makes space for a variety (...) of different formats, and is intimately tied to the computational approach to cognition in cognitive science and artificial intelligence.

Jonas Olson presents a critical survey of moral error theory, the view that there are no moral facts and so all moral claims are false.

An influential view in cognitive science is that computation in cognitive systems is semantic, conceptually depending on representation: to compute is to manipulate representations. I argue that accepting the non-semantic teleomechanistic view of computation lays the ground for a promising alternative strategy, in which computation helps to explain and naturalise representation, rather than the other way around. I show that this computation-based approach to representation presents six decisive advantages over the semantic view. I claim that it can improve the two (...) most influential current theories of representation, teleosemantics and structural representation, by providing them with precious tools to tackle some of their main shortcomings. In addition, the computation-based approach opens up interesting new theoretical paths for the project of naturalising representation, in which teleology plays a role in individuating computations, but not representations.

I analyze a tension at the core of the mechanistic view of computation generated by its joint commitment to the medium independence of computational vehicles and to computational systems possessing teleological functions to compute. While computation is individuated in medium-independent terms, teleology is sensitive to the constitutive physical properties of vehicles. This tension spells trouble for the mechanistic view, suggesting that there can be no teleological functions to compute. I argue that, once considerations about the relevant function-bestowing factors for computational (...) systems are brought to bear, the tension dissolves: physical systems can have the teleological function to compute.

Experiences—visual, emotional, or otherwise—play a role in providing us with justification to believe claims about the world. Some accounts of how experiences provide justification emphasize the role of the experiences’ distinctive phenomenology, i.e. ‘what it is like’ to have the experience. Other accounts emphasize the justificatory role to the experiences’ etiology. A number of authors have used cases of cognitively penetrated visual experience to raise an epistemic challenge for theories of perceptual justification that emphasize the justificatory role of phenomenology rather (...) than etiology. Proponents of the challenge argue that cognitively penetrated visual experiences can fail to provide the usual justification because they have improper etiologies. However, extant arguments for the challenge’s key claims are subject to formidable objections. In this paper, I present the challenge’s key claims, raise objections to previous attempts to establish them, and then offer a novel argument in support of the challenge. My argument relies on an analogy between cognitively penetrated visual and emotional experiences. I argue that some emotional experiences fail to provide the relevant justification because of their improper etiologies and conclude that analogous cognitively penetrated visual experiences fail to provide the relevant justification because of their etiologies, as well.

We discuss the idea that superpositions in quantum mechanics may involve contradictions or contradictory properties. A state of superposition such as the one comprised in the famous Schrödinger’s cat, for instance, is sometimes said to attribute contradictory properties to the cat: being dead and alive at the same time. If that were the case, we would be facing a revolution in logic and science, since we would have one of our greatest scientific achievements showing that real contradictions exist.We analyze that (...) claim by employing the traditional square of opposition.We suggest that it is difficult to make sense of the idea of contradiction in the case of quantum superpositions. From a metaphysical point of view the suggestion also faces obstacles, and we present some of them. (shrink)

Philosophers have disagreed on the composition of force for decades. The main divergence concerns the fundamental question: given a certain motion that is observable, which force or forces are present in it, component or resultant forces? The present paper focuses on the conditions for dealing with this problem. I will argue that we are not able to infer force from the observation of a motion, as required by the problem. I will further argue that the validity of the Newtonian algorithm (...) is not a sufficient condition for that inference because the Gaussian algorithm, which is equally valid, differs from the former with regard to the forces present in motions. Under these circumstances, I will make recourse to an experiment available in physics in which the force present in a motion is measured. Thus, we obtain a numerical value for this force. This result, playing the role of a counterexample, clarifies the composition of force issue significantly. (shrink)

The principle of conservation of energy tells us that ‘energy can neither be created nor destroyed but only transformed’. The validity of the principle is without question. The problem is the concept. Contemporary physicists have asserted that we do not know what energy is. We find, however, 19th century physicists, contemporary physicists and historians of science who converge on the point: Mayer and Joule discovered energy. Therefore, we do not know what energy is, but we know these authors discovered it. (...) What did they then discover? What can we learn from this with regard to the energy concept problem? To deal with this issue, I will distinguish between what the authors did experimentally and what they said about the phenomena. This method of analysis makes the difference in relation to historical works on the subject. In a second step, I will consider the introduction of the energy concept, which is from 1850s, and the reification of the energy in 1880s. Finally, I will address the energy conservation principle and the concept of energy conveyed by this principle in contemporary textbooks. As we shall see, the conservation of a magnitude that we call energy nowadays was discovered by Mayer and Joule; an indestructible and transformable entity was not. Adopting the original conservation principle would be enough to avoid the energy concept problem. (shrink)

This book provides a solution to the problem with the energy concept. This problem manifests itself in the fact that physicists clearly diverge regarding the question of what energy is. Some define it but others state that we do not know what it is. Although this is a problem for physicists who need to explain the concept, it is not a problem for physics that can be solved by laboratory means. Penetrating into the origin of the notion of energy, this (...) book offers a clear idea of what was discovered and what was invented to interpret the findings. Following the development of the concept, it provides an explanation of the trends in contemporary textbooks. The author's repetition, in his "History and Philosophy of Physics Laboratory", of Joule’s famous experiment – the paddle wheel experiment – with a calorimeter as originally used by Joule and with a calorimeter as proposed in textbooks, is presented, yielding new insight into the phenomenon. Thus, science teachers and students will benefit from reading the book as well as historians, philosophers, students of the history and philosophy of science, and all who are interested in knowing about what it is that we call energy.

How does history relate to the past? According to leading historical theorists, the relation to the past in history is reducible to evidential, psychological, practical and retrospective concerns.

The book provides a much-needed (...) philosophical clarification of key concepts in one of the most fundamental debates within the humanities today. (shrink)

Following J.-Y.Béziau in his pioneer work on non-standard interpretations of the traditional square of opposition, we have applied the abstract structure of the square to study the relation of opposition between states in superposition in orthodox quantum mechanics in [1]. Our conclusion was that such states are contraries, contradicting previous analyzes that have led to different results, such as those claiming that those states represent contradictory properties. In this chapter we bring the issue once again into the center of the (...) stage, but now discussing the metaphysical presuppositions which underlie each kind of analysis and which lead to each kind of result, discussing in particular the idea that superpositions represent potential contradictions. We shall argue that the analysis according to which states in superposition are contrary rather than contradictory is still more plausible. (shrink)

In this work, we focus on a very specific case study: assuming that quantum theories deal with “particles” of some kind, what kind of entity can such particles be? One possible answer, the one we shall examine here, is that they are not the usual kind of object found in daily life: individuals. Rather, we follow a suggestion by Erwin Schrödinger, according to which quantum mechanics poses a revolutionary kind of entity: non-individuals. While physics, as a scientific field, is not (...) concerned with whether entities posited by a specific physical theory are individuals or not, answering this question is part of the quest for a better understanding of physical reality. Here lies, in large measure, the relevance of ontology. (shrink)

The strategy of developing an ontology or models of disability as a prior step to settling ethical issues regarding disabilities is highly problematic for two reasons. First, key definitional aspects of disability are normative and cannot helpfully be made value-neutral. Second, if we accept that the contested concept of disability is value-laden, it is far from obvious that there are definitive reasons for choosing one interpretation of the concept over another. I conclude that the concept of disability is better left (...) ethically open-ended or broad enough to encompass the examination of various ethical issues. Alternatively, the concept of disability could be altogether abandoned in order to focus on specific issues without being hindered by debates about the nature of disability. Only political costs, rather than conceptual considerations internal to the models, could be weighed against such a conclusion. (shrink)

This paper concerns how extant theorists of predictive coding conceptualize and explain possible instances of cognitive penetration. §I offers brief clarification of the predictive coding framework and relevant mechanisms, and a brief characterization of cognitive penetration and some challenges that come with defining it. §II develops more precise ways that the predictive coding framework can explain, and of course thereby allow for, genuine top-down causal effects on perceptual experience, of the kind discussed in the context of cognitive penetration. §III develops (...) these insights further with an eye towards tracking one extant criterion for cognitive penetration, namely, that the relevant cognitive effects on perception must be sufficiently direct. Throughout these discussions, we extend the analyses of the predictive coding models, as we know them. So one open question that surfaces is how much of the extended analyses are genuinely just part of the predictive coding models, or something that must be added to them in order to generate these additional explanatory benefits. In §IV, we analyze and criticize a claim made by some theorists of predictive coding, namely, that (interesting) instances of cognitive penetration tend to occur in perceptual circumstances involving substantial noise or uncertainty. It is here that our analysis is most critical. We argue that, when applied, the claim fails to explain (or perhaps even be consistent with) a large range of important and uncontroversially interesting possible cases of cognitive penetration. We conclude with a general speculation about how the recent work on the predictive mind may influence the current dialectic concerning top-down effects on perception. (shrink)

Scientific realism is typically associated with metaphysics. One current incarnation of such an association concerns the requirement of a metaphysical characterization of the entities one is being a realist about. This is sometimes called “Chakravartty’s Challenge”, and codifies the claim that without a metaphysical characterization, one does not have a clear picture of the realistic commitments one is engaged with. The required connection between metaphysics and science naturally raises the question of whether such a demand is appropriately fulfilled, and how (...) metaphysics engages with science in order to produce what is called “scientific metaphysics”. Here, we map some of the options available in the literature, generating a conceptual spectrum according to how each view approximates science and metaphysics. This is done with the purpose of enlightening the current debate on the possibility of epistemic warrant that science could grant to such a metaphysics, and how different positions differently address the thorny issue concerning such a warrant.

Nonrelativistic quantum mechanics (QM) works perfectly well for all practical purposes. Once one admits, however, that a successful scientific theory is supposed not only to make predictions but also to tell us a story about the world in which we live, a philosophical problem emerges: in the specific case of QM, it is not possible to associate with the theory a unique scientific image of the world; there are several images. The fact that the theory may be compatible with distinct (...) ontologies, and that those ontologies may themselves be associated with a plurality of metaphysical approaches, gives rise to the problem of metaphysical underdetermination. This paper concludes that the available metametaphysical criteria fail to deliver objectivity in theory choice, and it puts forward its own criterion based on a tension between two methods of metaphysical inquiry: one that is closely related to science and another that is not.

In view of the posthumous Nietzschean writings, written between the years 1872 and 73, the scope of this paper is to investigate the place and function of philosopher in culture. We will analyze to what extent Nietzsche thought the nature of philosophical framework and the complex relation that philosophy establishes with science and with art. Regarding its edifying purposes, philosophy departs from the aims of science, which is the production of pure knowledge, and goes towards the uplifting goal of art.

In this paper we deal with two applications of the square of opposition to controversial issues in the philosophy of quantum mechanics. The first one concerns the kind of opposition represented by states in superposition. A superposition of “spin up” and “spin down” for a given spatial direction, for instance, is sometimes said to originate particular kinds of opposition such as contradictoriness. The second application concerns the problem of identical particles. Identity and indiscernibility are entangled in discussions of this problem (...) in such a way that a proper conceptual treatment of those issues through the square seems profitable. (shrink)
