Free Will and Neuroscience

Neuroscience and the Illusion of Free WillCurrently, few neuroscientists and philosophers still defend the claim that neuroscience has shown the brain ‘decides’ what we do and that free will is an illusion. This does not imply, however, that this kind of neuroscientific research could not say anything about the existence of free will. Neuroscience can offer insights in the unconscious causes and underlying processes of our actions and, because of this, could perhaps show whether we act out of free will (...) or not. In this paper I will argue that in this regard the possibilities of neuroscientific research are limited. I understand free will, in line with Dana Nelkin and Susan Wolf, as the ability to do the right thing for the right reasons. I will show that whether someone acts intentionally, what it is that she is doing, and for which reasons she acts cannot be determined by studying unconscious causes or other unconscious processes related to the action. The action and reason necessarily depend on the perspective of the acting agent. Furthermore, neuroscientific research cannot show us whether the reasons and the actions are right. It could perhaps offer a unique contribution when it comes to the question of whether we are able to the right thing for the right reasons. To what extent it can remains an open question. (shrink)

In this article we study the question of free will from an interdisciplinary angle, drawing on philosophy, neurobiology and physics. We start by reviewing relevant neurobiological findings on the functioning of the brain, notably as presented in (Koch 2009); we assess these against the physics of (in)determinism. These biophysics findings seem to indicate that neuronal processes are not quantum but classical in nature. We conclude from this that there is little support for the existence of an immaterial ‘mind’, capable of (...) ruling over matter independently of the causal past. But what, then, can free will be ? We propose a compatibilist account that resonates well with neurobiology and physics, and that highlights that free will comes in degrees – degrees which vary with the conscious grasp the ‘free’ agent has over his actions. Finally, we analyze the well-known Libet experiment on free will through the lens of our model. We submit this interdisciplinary investigation as a typical case of naturalized philosophy: in our theorizing we privilege assumptions that find evidence in science, but our conceptual work also suggests new avenues for research in a few scientific disciplines.

Neuroexistentialism brings together some of the world's leading philosophers, neuroscientists, cognitive scientists, and legal scholars to tackle our neuroexistentialist predicament and explore what the mind sciences can tell us about morality, love, emotion, autonomy, consciousness, selfhood, free will, moral responsibility, criminal punishment, meaning in life, and purpose.

This article addresses two influential lines of argument for what might be termed “scientific epiphenomenalism” about conscious intentions – the thesis that neither conscious intentions nor their physical correlates are among the causes of bodily motions – and links this thesis to skepticism about free will and moral responsibility. One line of argument is based on Benjamin Libet’s neuroscientific work on free will. The other is based on a mixed bag of findings presented by social psychologist Daniel Wegner. It is (...) argued that both lines of argument are unsuccessful. (shrink)

In this essay I critically examine Daniel Wegner’s account of conscious will as an illusion developed in his book The Illusion of Conscious Will. I show that there are unwarranted leaps in his argument, which considerably decrease the empirical plausibility and theoretical adequacy of his account. Moreover, some features essential to our experience of willing, which are related to our general understanding of free will, moral responsibility and human agency, are largely left out in Wegner’s account of conscious will. This (...) substantially diminishes its implications and significance for some profound philosophical issues. (shrink)

"La gente dice una y otra vez que la filosofía no progresa realmente, que todavía estamos ocupados con los mismos problemas filosóficos que los griegos. Pero la gente que dice esto no entiende por qué tiene que ser así. Es porque nuestro lenguaje ha permanecido igual y nos sigue seduciendo para que hagan las mismas preguntas. Mientras siga habiendo un verbo "ser" que parezca como si funciona de la misma manera que "comer y beber", siempre y cuando todavía tengamos los (...) adjetivos "idénticos", "verdaderos", "falsos", "posibles", siempre y cuando sigamos hablando de un río de tiempo, , de una extensión de espacio, etc., etc., la gente seguirá tropezando con las mismas dificultades desconcertante y se encontrará mirando a algo que ninguna explicación parece capaz de aclarar. Y lo que es más, esto satisface un anhelo de lo trascendente, porque, en la medida en que la gente cree que puede ver el ‘límites de la comprensión humana ́, creen, por supuesto, que pueden ver más allá de estos. ' ' Esta cita es de Ludwig Wittgenstein que redefinió la filosofía hace unos 70 años (pero la mayoría de la gente todavía tiene que averiguarlo). Dennett, aunque ha sido un filósofo desde hace unos 40 años, es uno de ellos. También es curioso que tanto él como su antagonista principal, John Searle, estudiaron bajo los famosos Wittgensteinianos (Searle con John Austin, Dennett con Gilbert Ryle) pero Searle Más o menos consiguió el punto y Dennett no, (aunque se está estirando cosas para llamar Searle o Ryle Wittgensteinianos). Dennett es un determinista duro (aunque intenta escabullirse de la realidad en la puerta trasera), y tal vez esto se deba a Ryle, cuyo famoso libro ́el concepto de la mente ́ (1949) continúa siendo reimpreso. Ese libro hizo un gran trabajo de exorcizar al fantasma, pero dejó la máquina. A Dennett le gusta cometer los errores que Wittgenstein, Ryle (y muchos otros desde entonces) han expuesto en detalle. Nuestro uso de las palabras consciencia, elección, libertad, intención, partícula, pensamiento, determina, oleada, causa, ocurrió, evento (y así sucesivamente) raramente son una fuente de confusión, pero tan pronto como dejamos la vida normal y entramos en la filosofía (y cualquier discusión separada del entorno en el que el lenguaje evolucionó— es decir, el contexto exacto en el que las palabras tenían sentido) reina el caos. Como la mayoría, Dennett carece de un marco coherente - que Searle ha llamado la estructura lógica de la racionalidad. Me he expandido en este considerablemente desde que escribí esta reseña y mis artículos recientes muestran en detalle lo que está mal con el enfoque de Dennett a la filosofía, que uno podría llamar scientismo en esteroides. Permítanme terminar con otra cita de Wittgenstein--́la ambición es la muerte del pensamiento ́.

This second edition of The Oxford Handbook of Free Will is intended to be a sourcebook and guide to current work on free will and related subjects.

Santiago Ramón y Cajal practice what became neuroscience in the remote town of Ayerbe, Aragón Spain. He struggled to travel to conferences in northern Europe to share his remarkable discovery.

This chapter pursues the question of naturalism in the context of non-Western philosophical contributions to ethics and philosophy of mind: First, what conception of naturalism, if any, is best suited to capture the scope of Buddhist Reductionism? And second, whether such a conception can still accommodate the distinctive features of phenomenal consciousness (e.g., subjectivity, intentionality, first-person givenness, etc.). The first section reviews dominant conceptions of naturalism, and their applicability to the Buddhist project. In the second section, the author provides an (...) example of problematic issues more stringent conceptions of naturalism under the guise of neurophysicalism confront, and evaluate Flanagan’s response to these issues. The third section considers briefly the reflexivity thesis (the thesis that consciousness consists in conscious mental states being implicitly self-aware), specifically as articulated by Dignaga, Dharmakirti and their followers, and uses this thesis to articulate a conception of minimal agency as mineness that, the author argues, further challenges Flanagan’s neurophysicalism stance and his compatibilist account of moral agency. The paper concludes, in the fourth section, by suggesting a way in which no-ownership conceptions of reflexive self-consciousness can help us both to get the structure of phenomenal consciousness right and to ground our conceptions of agency, intentionality, and moral responsibility.

“Dalla filosofia dell’azione alla filosofia della mente” è stato il percorso di alcuni filosofi di nazionalità varia degli anni 1980 – come Paul Churchland negli Stati Uniti o Ansgar Beckermann in Germania – che prima si sono interessati agli aspetti più teorici nella filosofia dell’azione, come il modo di funzionamento delle azioni e la loro spiegazione scientifica, e che poi, con l’arrivo e la diffusione dei personal computers e delle scienze cognitive, hanno ampliato e approfondito questo interesse di ricerca e (...) si sono dedicati alla filosofia della mente più in generale e in particolare alla spiegazione scientifica e filosofica del mentale. Sandro Nannini faceva parte di questo movimento ed è stato uno tra gli inizialmente pochi filosofi italiani che si sono occupati di questi argomenti; successivamente ne è diventato uno dei maggiori specialisti in Italia, proponendo una sua particolare versione di naturalizzazione del mentale. Subordinata agli interessi teorici è stata la sua iniziativa accademica di fondare e promuovere il primo dottorato italiano di ricerca in Scienze Cognitive. Il presente volume tratta dell’opera di Sandro Nannini in contributi che sono riflessioni più o meno specifiche sulle differenti tappe del suo percorso, affrontando temi come l’analisi dell'azione, il libero arbitrio, la discussione di Nannini di vari classici della filosofia, la tendenza del naturalismo a dissolvere la filosofia in un enciclopedismo empirico e la sfida dei qualia e della fenomenologia all’approccio naturalistico alla mente. Il volume contiene inoltre un saggio dello stesso Sandro Nannini, nel quale espone l’ultimo sviluppo della sua filosofia della mente nonché le risposte agli interventi degli altri autori: Mario De Caro, Sara Dellantonio, Rosaria Egidi, Roberta Lanfredini, Christoph Lumer, Paolo Parrini, Pietro Perconti, Claudio Pizzi, Emanuela Scribano e Giuseppe Varnier.

La hipótesis del marcador somático (SMH) ha sido una de las teorías más influyentes en las neurociencias desde principios de los años 90s en que fue formulada por Antonio Damasio en su libro El error de Descartes (1994). Desde entonces, diversos estudios, a favor y en contra se han escrito, sin un veredicto. En este trabajo se propone una explicación abarcadora de lo que es la hipótesis del marcador somático. En segundo lugar, se hace una valoración sucinta del peso que (...) la amígdala pueda tener en el proceso de toma de decisiones inconscientes. En contraste, se citan algunos resultados que apuntan que la corteza prefrontal ventromedial estaría comprometida con nuestras decisiones racionales. Finalmente, se recuperan algunas críticas de otros investigadores a la hipótesis del marcador somático a partir de resultados mixtos obtenidos en el juego de azar y apuestas de Iowa. Se concluye que la mayor valía de la SMH es haber terminado con la dualidad cerebro-cuerpo, pero que la hipótesis por sí misma, no es suficiente para sostener que el proceso de toma de decisiones se realice principalmente a partir de lo que sentimos. El proceso de toma de decisiones, si bien se vale de respuestas inconscientes somatosensoriales, es un proceso físico-emocional-racional más complejo, que carece aún de suficientes evidencias para ser situado. The somatic marker hypothesis (SMH) has been one of the most influential theories in the neurosciences since the early 1990s, when it was formulated by Antonio Damasio in his book Descartes’ Error (1994). Since then, various studies, for and against, have been written without a verdict. Firstly, this study provides a comprehensive explanation of the SMH. Secondly, it provides a detailed assessment of the relevance of the amygdala in the process of making unconscious decisions. In contrast, we cite some results that suggest that the ventromedial prefrontal cortex would be involved in our rational decisions. Finally, we review some of the criticism of the SMH that was based on the mixed results obtained in the Iowa Gambling Task. We suggest that the main value of the SMH is that it resolves the brain-body duality problem. However, the hypothesis by itself is insufficient to claim that the decision-making process is mainly based on our feelings. Although the decision-making process uses unconscious somatosensory responses, it is a more complex physical-emotional-rational process, which still lacks sufficient evidence to be located. (shrink)

In the theoretical literature on moral responsibility, one sometimes comes across cases of manipulated agents. In cases of this type, the agent is a victim of wholesale manipulation, involving the implantation of various pro-attitudes along with the deletion of competing pro-attitudes. As a result of this manipulation, the agent ends up performing some action unlike any that she would have performed were it not for the manipulation. These sorts of cases are sometimes thought to motivate historical views of responsibility, on (...) which the agent’s past is relevant to whether she is responsible for a specific action. In a recent paper, Daniel Sharp and David Wasserman bring these theoretical discussions on moral responsibility to bear on practical issues regarding neurological modifications of individuals. After proposing and arguing for a historical view, Sharp and Wasserman offer some insight into how such a view may help us in determining the responsibility of subjects who have undergone Deep Brain Stimulation. This paper aims to join this discussion, by arguing that the correct historical view to be applied will also appeal to the agent’s control over her mental life and the fact that this was bypassed. I conclude with some brief comments on the practical implications of such a historical view. (shrink)

If humans are purely physical, and if it is the brain that does the work formerly assigned to the mind or soul, then how can it fail to be the case that all of our thoughts and actions are determined by the laws of neurobiology? If this is the case, then free will, moral responsibility, and, indeed, reason itself would appear to be in jeopardy. Murphy and Brown present an original defence of a non-reductive version of physicalism whereby humans are (...) the authors of their own thoughts and actions. (shrink)

The claim of this article is that no event can determine a later event and that in this sense there cannot be sufficient causes. Therefore the causal structure of the world does not exclude free will, even if there are no chance processes.

Those who argue that free will is an illusion are wrong. They base their argument on scientific evidence that tests the wrong level of description for intentional action. Free will is not about subpersonal neuronal processes, muscular activation, or basic bodily movements, but about contextualized actions in a system that is larger than many contemporary philosophers of mind, psychologists, and neuroscientists consider. In this paper, I describe the kind of intentionality that goes with the exercise of free will.

Science in a Free Society is the sequel to Feyerabend's earlier iconoclastic, provocative book, Against Method. As he states in the preface: "Like the earlier book this volume has one aim: to remove obstacles intellectuals and specialists create for traditions different from their own and to prepare the removal of the specialists themselves from the life centers of society". The book is divided into three parts: Part 1 resumes the argument presented in Against Method; part 2 extends the implications of (...) that position to the conception of a "free society"; and part 3 contains a revealing autobiographical account along with answers to his critics--no less inhibited in style than his earlier book. Thus the conclusions in this volume should be viewed as an extension of the arguments of the previous essay. (shrink)

Skepticism about free will is increasingly often associated with the results of some empirical tests – launched by Libet’s trailblazing experiments on the timing of conscious intentions – aiming to teach us that our apparently free choices are originated unconsciously. In the present paper, I present some theoretical reasons to doubt if the upshots of Libet-like experiments purport to the revolutionary consequences they envisage. I will isolate a couple of points I wish to discuss, since they gained much attention in (...) the recent philosophical debate. First, I claim that actually available neuroscientific data do not offer a solution to the traditional free will quarrel in compatibilist or incompatibilist terms. Second, one might doubt if the kind of free will that is at stake in Libet-like experiments is what really matters for grounding our normative concepts. My conclusion will be that what is scrutinised in Libet-like experiments resembles palely the kind of free will we would like to enjoy. (shrink)

Introduction to a special issue on the Philosophy and Science of Mind.

Before commenting on the book, I offer comments on Wittgenstein and Searle and the logical structure of rationality. The essays here are mostly already published during the last decade (though some have been updated), along with one unpublished item, and nothing here will come as a surprise to those who have kept up with his work. Like W, he is regarded as the best standup philosopher of his time and his written work is solid as a rock and groundbreaking throughout. (...) However, his failure to take the later W seriously enough leads to some mistakes and confusions. Just a few examples: on p7 he twice notes that our certainty about basic facts is due to the overwhelming weight of reason supporting our claims, but W showed definitively in ‘On Certainty’ that there is no possibility of doubting the true-only axiomatic structure of our System 1 perceptions, memories and thoughts, since it is itself the basis for judgment and cannot itself be judged. In the first sentence on p8 he tells us that certainty is revisable, but this kind of ‘certainty’, which we might call Certainty2, is the result of extending our axiomatic and nonrevisable certainty (Certainty1) via experience and is utterly different as it is propositional (true or false). This is of course a classic example of the “battle against the bewitchment of our intelligence by language” which W demonstrated over and over again. One word- two (or many) distinct uses. -/- His last chapter “The Unity of the Proposition” (previously unpublished) would also benefit greatly from reading W’s “On Certainty” or DMS’s two books on OC (see my reviews) as they make clear the difference between true only sentences describing S1 and true or false propositions describing S2. This strikes me as a far superior approach to S’s taking S1 perceptions as propositional since they only become T or F after one begins thinking about them in S2. However, his point that propositions permit statements of actual or potential truth and falsity, of past and future and fantasy, and thus provide a huge advance over pre or protolinguistic society, is cogent. As he states it “A proposition is anything at all that can determine a condition of satisfaction…and a condition of satisfaction… is that such and such is the case.” Or, one needs to add, that might be or might have been or might be imagined to be the case. -/- Overall, PNC is a good summary of the many substantial advances over Wittgenstein resulting from S’s half century of work, but in my view, W still is unequaled once you grasp what he is saying. Ideally, they should be read together: Searle for the clear coherent prose and generalizations, illustrated with W’s perspicacious examples and brilliant aphorisms. If I were much younger I would write a book doing exactly that. -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my book ‘The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle’ 2nd ed (2019).

After half a century in oblivion, the nature of consciousness is now the hottest topic in the behavioral sciences and philosophy. Beginning with the pioneering work of Ludwig Wittgenstein in the 1930’s (the Blue and Brown Books) and from the 50’s to the present by his logical successor John Searle, I have created the following table as a heuristic for furthering this study. The rows show various aspects or ways of studying and the columns show the involuntary processes and voluntary (...) behaviors comprising the two systems (dual processes) of the Logical Structure of Consciousness (LSC), which can also be regarded as the Logical Structure of Rationality (LSR-Searle), of behavior (LSB), of personality (LSP), of reality (LSOR), of Intentionality (LSI) -the classical philosophical term, the Descriptive Psychology of Consciousness (DPC) , the Descriptive Psychology of Thought (DPT) –or better, the Language of the Descriptive Psychology of Thought (LDPT), terms introduced here and in my other very recent writings. -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my book ‘The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle’ 2nd ed (2019).

Given dramatic increases in recent decades in the pace of scientific discovery and understanding of the functional organization of the brain, it is increasingly clear that engagement with the neuroscientific literature and research is central to making progress on philosophical questions regarding the nature and scope of human freedom and responsibility. While patterns of brain activity cannot provide the whole story, developing a deeper and more precise understanding of how brain activity is related to human choice and conduct is crucial (...) to the development of realistic, just, and intellectually rigorous models of human agency and moral responsibility. In this special issue, we acknowledge that “free will” and “moral responsibility” are not concepts with which neuroscience can directly engage, and instead focus on self-governance, and the capacities that contribute to self-governance, which are more tractable for scientific investigation and are prerequisites for the presence of moral responsibility.

Trends in experimental philosophy have provided new and compelling results that are cause for re-evaluations in contemporary discussions of free will. In this paper, I argue for one such re-evaluation by criticizing Robert Kane’s well-known views on free will. I argue that Kane’s claims about pre-theoretical intuitions are not supported by empirical findings on two accounts. First, it is unclear that either incompatibilism or compatibalism is more intuitive to nonphilosophers, as different ways of asking about free will and responsibility reveal (...) different answers. Secondly, I discuss how a study by Josh May supporting a cluster concept of free will may provide ethicists with a reason to give up a definitional model, and I discuss a direction future work might take. Both of these objections come from a larger project concerned with understanding the cognitive mechanisms that people employ when they make judgments about agency and responsibility—a project that promises not only to challenge contemporary philosophy, but to inform it.

This paper focuses on Gilberto Gomes’ work on free will. In a series of contributions that have had a significant impact on the respective literature, Gomes developed a conception about free will and argued that its existence is consistent with recent scientific findings, specially in neuroscience. In this paper, I object to a claim of Gomes about his conception of free will, namely the claim that it is a compatibilist conception. I seek to show that Gomes does not use the (...) term ‘compatibilism’ as it is usual in the contemporary literature on free will, i.e., as the thesis that free will can exist even if determinism is true. Moreover, the conception of free will Gomes proposes actually has an incompatibilist commitment. I argue that, more than a mere terminological point, acknowledging the incompatibilist aspect of Gomes’ view motivates important questions about the details of the view and helps to reveal a limitation of his defense of the existence of free will. [Este artigo tem como tema o trabalho de Gilberto Gomes sobre o livre-arbítrio. Em uma série de contribuições que tiveram um impacto significativo na respectiva literatura, Gomes elaborou uma concepção sobre o livre-arbítrio e argumentou que sua existência é consistente com descobertas científicas recentes, especialmente na neurociência. Neste artigo, questiono uma afirmação de Gomes sobre sua concepção sobre o livre-arbítrio, a saber, que se trata de uma concepção compatibilista. Busco mostrar que Gomes não usa o termo ‘compatibilismo’ como é habitual na literatura contemporânea sobre o livre-arbítrio, isto é, como a tese segundo a qual o livre-arbítrio pode existir ainda que o determinismo seja verdadeiro. Ademais, a concepção sobre o livre-arbítrio desenvolvida por Gomes tem, efetivamente, um compromisso incompatibilista. Argumento que, mais do que uma mera elucidação terminológica, reconhecer o elemento incompatibilista presente na proposta de Gomes suscita questões importantes sobre os detalhes da proposta e também ajuda a reconhecer uma limitação de sua defesa da existência do livre-arbítrio.].

While the presence or absence of consciousness plays the central role in the moral/ethical decisions when dealing with patients with disorders of consciousness (DOC), recently it is criticized as not adequate due to number of reasons, among which are the lack of the uniform definition of consciousness and consequently uncertainty of diagnostic criteria for it, as well as irrelevance of some forms of consciousness for determining a patient’s interests and wishes. In her article, Dr. Specker Sullivan reexamined the meaning of (...) consciousness in the DOC taxonomy and proposed to go away from the routinely used clinical definition of consciousness as “wakeful awareness”, and adopt the meaning that is common in the Eastern tradition which is a form of “pure experience” (Specker Sullivan 2018). She further argued that understanding consciousness as a “pure experience” is ethically relevant for DOC patients. This suggestion is original, novel and important since it preserves the importance of the notion of consciousness for the clinical practice while simultaneously offering an additional ethical tool for the moral decisions in medicine. At the same time, without placing such Eastern notion in the Western tradition it is difficult to see how pure experience could be usefully operationalized to make sense in the clinical practice with DOC patients. It is so because pure experience is a subjective phenomenon which is completely inaccessible in noncommunicative DOC patients and also it does not express behaviorally (Monti et al 2010), therefore some objective-like operationalization is needed. This is why the fusion of Eastern and Western traditions is required to gain the full potential of Dr. Specker Sullivan’s suggestion. We propose that such fusion could be achieved on the basis of the Operational Architectonics (OA) theory of brain-mind functioning (Fingelkurts et al. 2010; 2013a) which suits ideally the purpose due its compatibility with both Western and Eastern traditions of consciousness.

Much recent work in neuroscience aims to shed light on whether we have free will. Can it? Can any science? To answer, we need to disentangle different notions of free will, and clarify what we mean by ‘empirical’ and ‘testable’. That done, my main conclusion is, duly interpreted: that free will is not a testable hypothesis. In particular, it is neither verifiable nor falsifiable by empirical evidence. The arguments for this are not a priori but rather are based on a (...) posteriori consideration of the relevant neuroscientific investigations, as well as on standard philosophy of science work on the notion of testability.

: In his book Free Will Sam Harris tries to persuade us to abandon the morally pernicious idea of free will. The following contribution articulates and defends a more sophisticated model of free will that is not only consistent with neuroscience and introspection but also grounds a variety of responsibility that justifies both praise and blame, reward and punishment. This begins with the long lasting parting of opinion between compatibilists and incompatibilists. While Harris dismisses compatibilism as a form of theology, (...) this article aims at showing that Harris has underestimated and misinterpreted compatibilism and at defending a more sophisticated version of compatibilism that is imprevious to Harris’ criticism. Keywords : Sam Harris; Free Will; Compatibilism; Incompatibilism; Neuroscience Riflessioni su "Free Will" di Sam Harris Riassunto : Nel suo libro Free Will Sam Harris cerca di persuaderci ad abbandonare l’idea, a suo avviso moralmente perniciosa, del libero arbitrio. Il contributo seguente articola e difende un modello di libero arbitrio che non solo è coerente con le neuroscienze e con l’introspezione, ma che dà anche fondamento a varie responsabilità giustificando encomi e biasimo, premi e punizioni. Questo prende le mosse dalla discussione della disputa di lunga data fra compatibilisti e incompatibilisti. Mentre Harris respinge il compatibilismo alla stregua di una forma di teologia, questo articolo ambisce a mostrare come Harris abbia sottostimato e mal interpretato il compatibilismo e come invece sia possibile enucleare una forma di compatibilismo più sofisticata, insensibile alle sue critiche. Parole chiave : Sam Harris; Libero arbitrio; Compatibilismo; Incompatibilismo; Neuroscienza. (shrink)

In this article, I discuss the importance of multidisciplinary research to tackle the questions that empirical sciences, and in particular neuroscience, ultimately encounter. The last decades have witnessed an enormous progress in brain research, mainly because of the improvement of neuroimaging techniques and neurogenetics, and the development of optogenetics. Furthermore, the US Government and European Union have launched the BRAIN Initiative and Human Brain Project, respectively, to promote a better understanding of brain functioning and its disorders. Unfortunately, their gates appear (...) sealed for disciplines that pursue a deep knowledge of the mind, such as philosophy or psychology. The most probable outcome of this situation is “promissory materialism”, as Sir John Eccles warned several decades ago. I review the multidisciplinary approach of Eccles to the study of the brain and mind, especially through his relationship with Mariano Artigas. Finally, I propose that interdisciplinary research may be improved by a more solid understanding of the discipline one wants to dialogue with, and a multidisciplinary training from the beginning of the research career.

Libet’s experimental setting has been criticized at length ever since its first appearance, under both methodological and empirical aspects. In this paper, the attention will be driven on a neglected underpinning theme which has not yet been investigated, central for the economy of the argument: the time of choices. The pivotal role played by mental chronometry at the beginning of psychology and neurophysiology will be pointed out, and how the lack of a proper definition of time affected the course of (...) the following research on the subject. The Aristotelian definition of time will be considered in order to cast some light upon Libet’s empirical findings. (shrink)

In this paper, I will take into account and criticize two of the most celebrated neuroscientific experiments about free will, which seem to deny that agents freely deliberate about simple choices of their everyday life: the pioneering experiment of Benjamin Libet and the more recent one of John Dylan Hayes. My aim is to reject the relevance of their empirical results, which deny the existence of free will. However, such a rejection will not rely on criticisms about how the experiments (...) are conducted. Instead, I would like to bring about a broad philosophical and methodological concern: namely, that the success or the failure of the experiments in arguing for the illusion of free will is strictly dependent on the meaning of the notion of free will which is put through an experimental investigation.

Talk at the ASSC4 conference (Brussels, 2000).

In seinem Buch Illusion freier Wille? verfolgt Sven Walter zwei Hauptziele. Das erste besteht in dem detaillierten Nachweis, dass die in den letzten beiden Jahrzehnten öffentlichkeitswirksam vorgetragene kognitions- und neurowissenschaftlich begründete Freiheitsskepsis durch die empirischen Befunde nicht gedeckt sei. Das zweite Hauptziel ist, aufzuzeigen, dass Willensfreiheit bzw. „unsere intuitive Freiheitsgewissheit“ durchaus empirisch erforschbaren Beeinträchtigungen unterliegt, aber anderen als von den Wortführern der neurobiologischen Freiheitskritik angeführten: „Unbewusste situationale Einflüsse“ auf unsere Willens- und Entscheidungsbildung seien zwar nicht per se, wohl aber dann (...) freiheitsbedrohend, „wenn sie dazu führen, dass sich unser Wille nicht mehr unserem rückhaltlosen Urteil darüber fügt, was zu tun richtig wäre“.

In a previous paper, I argued that neuroscience and psychology could in principle undermine libertarian free will by providing support for a subset of what I called “statements of local determination.” I also argued that Libet-style experiments have not so far supported statements of that sort. In a commentary to the paper, Adina Roskies and Eddy Nahmias accept the claim about Libet-style experiments, but reject the claim about the possibilities of neuroscience. Here, I explain why I still disagree with their (...) conclusion, despite being sympathetic to a lot of what they say in support of it. (shrink)

Este artigo pretende caracterizar de forma geral os posicionamentos fisicalistas na filosofia da mente e indicar como a questão do livre-arbítrio surge e pode ser crucial para tal corrente de pensamento. Primeiramente pretende mostrar a diferença entre a posição reducionista e a não-reducionista e depois salientar suas potencialidades e dificuldades na abordagem da questão do livre-arbítrio. Enfim, mesmo que a questão ainda fique em aberto, verificar-se-á que o livre-arbítrio parece não encontrar espaço no cenário apresentado pelas correntes fisicalistas.

Saigle, Dubljevic, and Racine (2018) claim that Libet-style experiments are insufficient to challenge that agents have free will. They support this with evidence from experimen- tal psychology that the folk concept of freedom is consis- tent with monism, that our minds are identical to our brains. However, recent literature suggests that evidence from experimental psychology is less than determinate in this regard, and that folk intuitions are too unrefined as to provide guidance on metaphysical issues like monism. In light of (...) this, it is worthwhile to examine the authors’ insuf- ficiency claim under the assumption that monism is false and dualism true (our minds are not identical to our brains). We conclude that, were dualism true, then Libet- style experiments would tell us no more about freedom and moral responsibility than what the authors initially claimed, thus further bolstering their point that Libet-style experiments are ill-suited to speak to the free will of agents. In what follows we first discuss some of the reasons to be skeptical of using folk intuitions to make claims about the nature of freedom and moral responsibility. We then draw from the work of E. J. Lowe to demonstrate that Libet-style experiments would likely give the same results regardless of the truth of monism or dualism. (shrink)

[Note: articles 1-5 are in English; Intro, Discussion, and Conclusion are in Portuguese.] Responsibility practices that are part of our daily lives involve, among other things, standards about how one should praise, blame, or punish people for their actions, as well as particular acts that follow those standards to a greater or lesser extent. A classical question in philosophy asks whether human beings can actually be morally responsible for what they do. This dissertation argues that addressing this classical question is (...) insufficient if one wants the investigation of moral responsibility to serve the goal of improving ordinary responsibility practices. As an alternative, I offer directions for an interdisciplinary investigation that I take to be in a better position to promote that goal. My argument is developed in five articles and a discussion section. The first four articles describe limitations of skeptical views, which deny the existence of moral responsibility. The first article assesses a skeptical argument based on results from neuroscience that intends to show that there is no free will. I argue that a premise in the argument—which says that choices are determined by events in the brain—is not supported by the available results. The second article argues that, despite the fact that existent results do not show that choices are determined by brain events, further studies in neuroscience could in principle do that. The third article begins the discussion of limitations that concern the implementability of some of the changes in responsibility practices recommended in skeptical approaches. Specifically, I describe challenges that attempts to reduce the severity of legal punishment are likely to face due to psychological facts about belief in free will and desire to punish. The forth article presents results from an original experiment that sought to test a hypothesis about the workings of belief in free will and the desire to punish, namely the hypothesis that the desire to punish causally affects beliefs about free will. Results failed to support the hypothesis. Finally, the fifth article presents what I call the enhancement model, i.e., a proposal about how to structure an interdisciplinary investigation that can promote the enhancement of ordinary responsibility practices. The final discussion section shows how the enhancement model overcomes some of the limitations of recent discussions about the existence of moral responsibility, which includes not just the skeptical views considered in earlier articles, but also views that affirm the existence of moral responsibility and free will. The central claim of this dissertation, therefore, is that the investigation of moral responsibility can be rearranged so as to further the goal of improving ordinary responsibility practices.

In this largely antimetaphysical treatment of free will and determinism, Mark Balaguer argues that the philosophical problem of free will boils down to an open scientific question about the causal histories of certain kinds of neural events. In the course of his argument, Balaguer provides a naturalistic defense of the libertarian view of free will. The metaphysical component of the problem of free will, Balaguer argues, essentially boils down to the question of whether humans possess libertarian free will. Furthermore, he (...) argues that, contrary to the traditional wisdom, the libertarian question reduces to a question about indeterminacy--in particular, to a straightforward empirical question about whether certain neural events in our heads are causally undetermined in a certain specific way; in other words, Balaguer argues that the right kind of indeterminacy would bring with it all of the other requirements for libertarian free will. Finally, he argues that because there is no good evidence as to whether or not the relevant neural events are undetermined in the way that's required, the question of whether human beings possess libertarian free will is a wide-open empirical question.

A neurophilosopher?s take on the self, free will, human understanding, and the experience of God, from the perspective of the brain.

This book addresses the fascinating cross-disciplinary field of quantum information theory applied to the study of brain function. It offers a self-study guide to probe the problems of consciousness, including a concise but rigorous introduction to classical and quantum information theory, theoretical neuroscience, and philosophy of the mind. It aims to address long-standing problems related to consciousness within the framework of modern theoretical physics in a comprehensible manner that elucidates the nature of the mind-body relationship. The reader also gains an (...) overview of methods for constructing and testing quantum informational theories of consciousness. (shrink)

Recent studies within neuroscience and cognitive psychology have explored the place of conscious willing in the generation of purposive action. Some have argued that certain findings indicate that the commonsensical view that we control many of our actions through conscious willing is largely or wholly illusory. I rebut such arguments, contending that they typically rest on a conflation of distinct phenomena. Nevertheless, I also suggest that traditional philosophical accounts of the will need to be revised: a raft of studies indicate (...) that control over one’s own will among human beings is limited, fragile, and – insofar as control depends to an extent on conscious knowledge – admitting of degrees. I briefly sketch several dimensions along which freedom of the will may vary over time and across agents. (shrink)

: To act is to be the author of an intentional bodily movement. I will show that, in order for that authorship to be assured, the agent must both amount to more than the mereological sum of her mental or neural states and events, and have an irreducible causal power over, at least, some of them. Hence, agent-causalism is the best position for any realist about action to assume. I will contend that, contrary to what many have claimed, agent-causalism is (...) not an unscientific theory, since it can ground its view of the agent on a form of emergent dualism that can account for robust forms of agency without having to challenge the natural supervenience of the mental on the physical. I claim that the conditions of possibility for a causally effective emergent self are the presence of neuronal indeterminism and the break of causal closure, both of which will be shown to be compatible with our current scientific picture of the world. Keywords: Action; Self; Emergent Dualism; Downward Causation; Indeterminism Prendere sul serio l’agente: ovvero, come un’attenta analisi dell’agentività ci conduce al dualismo emergentista Riassunto: Agire vuol dire essere l’autore di un movimento corporeo intenzionale. Intendo mostrare che, per assicurarsi il riconoscimento di essere l’autore di un’azione, l’agente debba essere più della semplice somma mereologica dei propri stati mentali ed eventi neurali e che debba anche avere un irriducibile potere causale su di essi, o al limite su parte di essi. Pertanto, una concezione causale riferita all’agente è la migliore posizione da assumere per chi voglia dirsi realista riguardo alle azioni. Intendo affermare che, diversamente a quanto da molti sostenuto, la concezione causale riferita all’agente non sia una teoria non scientifica, dal momento che può fondare la sua concezione dell’agente su una forma di dualismo emergentista in grado di legittimare forme robuste di agentività senza dover mettere in dubbio la sopravvenienza del mentale sul fisico. Indeterminismo neurale e rottura della chiusura causale saranno indicate come condizioni di possibilità per un sé causalmente ed effettivamente emergente e mostrerò come entrambi siano compatibili con l’immagine scientifica del mondo che oggi abbiamo. Parole chiave : Azione; Sé; Dualismo emergentista; Causalità rivolta verso il basso; Indeterminismo. (shrink)

Spontaneous actions are preceded by brain signals that may sometimes be detected hundreds of milliseconds in advance of a subject's conscious intention to act. These signals have been claimed to reflect prior unconscious decisions, raising doubts about the causal role of conscious will. Murakami et al. (2014. Nat Neurosci 17: 1574–1582) have recently argued for a different interpretation. During a task in which rats spontaneously decided when to abort waiting, the authors recorded neurons in the secondary motor cortex. The neural (...) activity and relationship to action timing was parsimoniously explained using an integration-to-bound model, similar to those widely used to account for evidence-based decisions. In this model, the brain accumulates spontaneously occurring inputs voting for or against an action, but only commits to act once a certain threshold is crossed. The model explains how spontaneous decisions can be forecast (partially predicted) by neurons that reflect either the input or output of the integrator. It therefore presents an explicit hypothesis capable of rejecting the claim that such predictive signals imply unconscious decisions. We suggest that these results can inform the current debate on free will but must be considered with caution. (shrink)

The concept of free will has been heavily debated in philosophy and the social sciences. Its alleged importance lies in its association with phenomena fundamental to our understandings of self, such as autonomy, freedom, self-control, agency, and moral responsibility. Consequently, when neuroscience research is interpreted as challenging or even invalidating this concept, a number of heated social and ethical debates surface. We undertook a content analysis of media coverage of Libet’s et al.’s :623–642, 1983) landmark study, which is frequently interpreted (...) as posing a serious challenge to the existence of free will. Media descriptions of Libet et al.’s experiment provided limited details about the original study. Overall, many media articles reported that Libet et al.’s experiments undermined the existence of free will, despite acknowledging that several methodological limitations had been identified in the literature. A propensity to attribute greater credibility than warranted to neurobiological explanations could be at stake. (shrink)

Philosophers and scientists have across the ages been amazed about the fact that development and learning often lead to not just a merely incremental and gradual change in the learner but sometimes to a result that is strikingly different from the learner’s original situation: amazed, but at times also worried. Both philosophical and cognitive neuroscientific insights suggest that experts appear to perform ‘different’ tasks compared to beginners who behave in a similar way. These philosophical and empirical perspectives give some insight (...) into what happens when a novice is transitioning to a stage of expertise. Generally, this implies that increased skill and expertise support better results and a more flexible performance, in part because these allow an agent to withdraw part of her attention and other cognitive resources from the tasks involved, enabling her to devote those resources to supporting, or completely different, tasks. As positive as these developments appear, these changes have also raised concerns. The main concern is whether gaining expertise is like raising a ‘cognitive monster’ which escapes the individual’s conscious control and influences her actions with undesirable automatisms. If so, we should ask ourselves whether experts are capable of taming this monster. The answer appears initially not to be positive. Indeed, it has been noted that since it is difficult for experts to withhold automatic responses this can lead to inflexibility or performance that is only optimal under certain conditions, because it is limited to a specific domain, often context-dependent, biased and inflexible. In what follows, I will consider this challenge of protecting expertise and harnessing this brittleness from philosophical and cognitive neuroscientific perspectives. Taking into account that action is in general determined by a multitude of factors, with learning and development affecting how these factors exert their influence, a philosophical question is how this complex and dynamic process can be explained and subsequently, how controlling it might be understood. First, though, I will present the issue at hand more closely: should we appreciate expertise if it is similar to growing a ‘cognitive monster’? Second, I will introduce the framework of a “Sculpted Space of Actions” (Keestra, 2014), which I developed in order to explain how the challenge of selecting an adequate option for action is facilitated by expertise as it helps to constrain the space of potential action options. Subsequently, the question is raised of how such a Sculpted Space of Actions influences an expert’s engagement with specific situations, like teaching students in a classroom setting. It will be argued that a well prepared expert—teacher or otherwise— is not only able to rely upon her routines but will at the same time be more perceptive and attentive to unforeseen events and actions, according to the recent cognitive neuroscientific theory of Predictive Processing. Integrating the theory of Predictive Processing with the Sculpted Space of Actions framework, I conclude that expertise contributes to adaptive and flexible responses to specific contexts, yet only if it is associated with explicit planning and articulation of situation specific intentions—the latter effectively putting the cognitive monster at rest for a while.

According to Bergson , the traditional problem of free will is misconceived and arises from a mismatch between the quality of authentic, subjective experience and its description in language, in particular, the language of the mechanistic science of psychology. Contemporary western scientific concepts of the organism, on the other hand, are leading us beyond conventional thermodynamics as well as quantum theory and offering rigorous insights which reaffirm and extend our intuitive, poetic, and even romantic notions of spontaneity and free will. (...) I shall describe some new views of the organism arising from new findings in biology, in order to show how, in freeing itself from the ‘laws’ of physics, from mechanical determinism and mechanistic control, the organism becomes a sentient, coherent being that is free, from moment to moment, to explore and create its possible futures.
