Free Will and Neuroscience

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.

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.

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. (shrink)

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)

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“. [...]. (shrink)

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.

Some psychologists and philosophers have argued that neuroscience is importantly relevant to our moral responsibility practices, especially to our practices of praise and blame. For consider: on an unprecedented scale, contemporary neuroscience presents us with a mechanistic account of human action. Furthermore, in uential studies – most notoriously, Libet et al. (1983) – seem to show that the brain decides to do things (so to speak) before we consciously make a decision. In light of these ndings, then – or so (...) some have argued – we ought to revise our practices of praise and blame. In the current paper, I argue that this conclusion is unwarranted. The reason is that the argument for it depends on controversial non-empirical premises, premises we need not accept. I suggest, however, that neuroscience does bear on our moral responsibility practices in one important, if less revisionary, way. In particular, neuroscience o ers a new kind of evidence for determining when agents should be held exempt from our normal moral responsibility practices. (shrink)

Has modern neuroscience shown that free will is an illusion? Those who give an affirmative answer often argue as follows. The overt actions that have been studied in some recent experiments do not have corresponding consciously made decisions or conscious intentions among their causes. Therefore no overt actions have corresponding consciously made decisions or conscious intentions among their causes. This paper challenges this inference, arguing that it is unwarranted.

Various authors have argued that progress in the neurocognitive and neuropsychiatric sciences might threaten the commonsense understanding of how the mind generates behavior, and, as a consequence, it might also threaten the commonsense ways of attributing moral responsibility, if not the very notion of moral responsibility. In the case of actions that result in undesirable outcomes, the commonsense conception—which is reflected in sophisticated ways in the legal conception—tells us that there are circumstances in which the agent is entirely and fully (...) responsible for the bad outcome and circumstances in which the agent is not at all responsible for the bad outcome.

The question of whether humans have free will, like the question of the meaning of life, is one whose answer depends on how the question itself is interpreted. In his recent book Neurophilosophy of Free Will: From Libertarian Illusions to a Concept of Natural Autonomy, Henrik Walter examines whether free will is possible in a deterministic natural world, and he concludes that the answer is "It depends" (xi). He rejects a libertarian account of free will as internally inconsistent, but argues (...) for a version of compatibilism that he calls "natural autonomy." Natural autonomy, or "giving oneself laws" (8), is a successor concept to libertarian free will, and it provides for a self-determination that is consistent with a deterministic and fully physical world. Walter covers a lot of ground in this book. He debunks dualism, examines classical and modern physics, critiques radical constructivism, and utilizes chaos theory, and he refers to figures from St. Augustine to Humberto Maturana, Dennett, Einstein, Hegel and Nozick. This book could be seen as encompassing two distinct projects. The first project is a defense of what Walter calls "neurophilosophy" as a methodology for answering traditional philosophical questions. This methodology is more commonly known as "cognitive science," and Walter accepts the naturalistic premises that underlie most of the work being done by cognitive scientists today. The second project is an application of the neurophilosophical methodology to the traditional question of whether free will is compatible with determinism. The defense of a neurophilosophical methodology is concentrated in the second section of the book, whereas the first and third sections focus on the issue of free will. In the first section Walter presents a thorough overview of the free will debate. It is the final third of the book that warrants the most attention, for this is where the original work is concentrated. Before we examine Walter's contribution to the free will debate, let us briefly look at his historical analysis and the neurophilosophical method that he advocates.. (shrink)

Advanced biological brains are by nature open-ended opportunistic controllers. Such controllers compute, pretty much on a moment-to-moment basis, what problem-solving resources are readily available and recruit them into temporary problem-solving wholes. Neural plasticity, exaggerated in our own species, makes it possible for such resources to become factored deep into both our cognitive and physical problem-solving routines. One way to think about this is to depict the biological brain as a master of what I shall dub ‘ecological control’. Ecological control is (...) the kind of top-level control that does not micro-manage every detail, but rather encourages substantial devolvement of power and responsibility. This kind of control allows much of our skill at walking to reside in the linkages and elastic properties of muscles and tendons. And it allows much of our prowess at thought and reason to depend upon the robust and reliable operation, often in dense brain-involving loops, of a variety of non-biological problem-solving resources spread throughout our social and technological surround. Are the complex distributed systems that result in some sense ‘out of control’, beyond the reach of useful governance? I shall argue that they are not, although understanding them requires us to re-think some key ideas about control and the nature of the self. To make this case, I shall first examine some strategies for efficient, external opportunity exploiting control in simple systems. I shall then argue that many of the same lessons apply to the case of higher-level human problem-solving. (shrink)

There continues to be a debate on whether addiction is best understood as a brain disease or a moral condition. This debate, which may influence both the stigma attached to addiction and access to treatment, is often motivated by the question of whether and to what extent we can justly hold addicted individuals responsible for their actions. In fact, there is substantial evidence for a disease model, but the disease model per se does not resolve the question of voluntary control. (...) Recent research at the intersection of neuroscience and psychology suggests that addicted individuals have substantial impairments in cognitive control of behavior, but this “loss of control” is not complete or simple. Possible mechanisms and implications are briefly reviewed. (shrink)

Chris Frith's target chapters contain a wealth of interesting experiments and striking theoretical claims. In these comments I begin by drawing out some of the key themes in his discussion of action and the sense of agency. Frith's central claim about conscious action is that what we are primarily conscious of in acting is our own agency. I will review some of the experimental evidence that he interprets in support of this claim and then explore the following three questions about (...) the awareness of agency: Should we locate the phenomena that Frith describes as awareness of agency at the personal level or at the subpersonal level? If we are indeed operating at the personal level, then should we think about awareness of agency as something we experience, or as something that we believe? If awareness of agency is to be understood experientially, is there what some authors have called “a sense of agency“, where this is understood to be a distinctive type of experience that accompanies agentive behaviors but is absent in behaviors that are not under the control of the agent? In what follows I argue that awareness of agency should be located at the personal level, and that we should think of it as something we experience . But I will reject the claim that there is a distinctive sense of agency. (shrink)

Recent empirical research results in the behavioral, cognitive, and neurosciences on the “adaptive unconscious” show that conscious control and deliberative awareness are not all-pervasive aspects of our everyday dealings with one another. Moral philosophers and other scientists have used these insights to put our moral agency to the test. The results of these tests are intriguing: apparently we are not always the moral agents we take ourselves to be. This paper argues in favor of a refinement of our common perception (...) of moral agency that can accommodate these results; however, it also argues against the suggestion that this refined concept is the result of a radical new understanding of our everyday moral practices.
