Unable to reconcile freedom of choice and the inexorable limitations of nature, common sense successively affirms a false unlimited and unsituated freedom, and a false determination of man by nature which reduces him to an object. On the ...

Richard Swinburne presents a powerful case for substance dualism and libertarian free will.

I was led to this clarificatory job initially by some puzzlement from a philosopher's standpoint about just why free will questions should come up particularly in connection with the genome project, as opposed to the many other scientific research programs that presuppose determinism. The philosophic concept of determinism involves explanation of all events, including human action, by prior causal factors--so that whether or not human behavior has a genetic basis, it ultimately gets traced back to _something_ true of the world (...) before our birth. The philosophic problem of free will and determinism arises because this seems to undercut moral responsibility: How can we reasonably be held responsible for something whose causes we couldn't control? (shrink)

There seems to be evidence of a genetic component in criminal behavior. It is widely agreed not to be "deterministic"--by which discussions outside philosophy seem to mean that by itself it is not sufficient to determine behavior. Environmental factors make a decisive difference--for that matter, there are nongenetic biological factors--in whether and how genetic.

Popular and scientific accounts of the U.S. Human Genome Project often express concern about the implications of the project for the philosophic question of free will and responsibility. However, on its standard construal within philosophy, the question of free will versus determinism poses no special problems in relation to genetic research. The paper identifies a variant version of the free will question, free will versus internal constraint, that might well pose a threat to notions of individual autonomy and virtue in (...) connection with genetic research. Whether it does depends on the extent to which the genetic basis for behavior turns on behavioral incapacities. (shrink)

We are discovering more and more about the human genotypes and about the connections between genotype and behaviour. Do these advances in genetic information threaten our free will? This paper offers a philosopher’s perspective on the question.

This paper aims to challenge the view that the sign present in many Frankfurt-style scenarios is insufficiently robust to constitute evidence for the possibility of an alternate decision, and therefore inadequate as a means of determining moral responsibility. I have amended Frankfurt’s original scenario, so as to allow Jones, as well as Black, the opportunity to monitor his (Jones’s) own inclination towards a particular decision (the sign). Different outcome possibilities are presented, to the effect that Jones’s awareness of his own (...) inclinations leads to the conclusion that the sign must be either (a) a prior determinate of the decision about to be made, (b) prior and indeterminate (therefore allowing for a contra-inclination decision to be made), or (c) constitutive of a decision that Jones has made but is not yet aware of. In effect, this means that, prior to the intervention of Black, Jones must have decided to do otherwise or could have so decided. Either way, although Frankfurt’s conclusion, that Jones could not have done other than he did, is upheld, the idea that he could not have decided otherwise must be rejected, and with it the view that the sign is nothing more than a flicker of freedom insufficient for assigning morally responsibility.

In this paper I argue that Robert Kane’s defense of event-causal libertarianism, as presented in Responsibility, Luck, and Chance: Reflections on Free Will and Indeterminism, fails because his event-causal reconstruction is incoherent. I focus on the notions of efforts and self-forming actions essential to his defense.

Free will sceptics claim that we do not possess free will—or at least, that we do not possess nearly as much free will as we think we do. Some free will sceptics hold that the very notion of free will is incoherent, and that no being could possibly possess free will (Strawson this volume). Others allow that the notion of free will is coherent, but hold that features of our cognitive architecture prevent us from possessing free will. My concern in (...) this chapter is with views of the second kind. According to an increasingly influential line of thought, our common-sense commitment to the existence of free will is threatened in unique ways by what we are learning from the sciences of human agency.

Free will sans metaphysics? Content Type Journal Article Pages 1-5 DOI 10.1007/s11016-011-9525-5 Authors Helen Beebee, Department of Philosophy, University of Birmingham, Birmingham, B15 2TT UK Journal Metascience Online ISSN 1467-9981 Print ISSN 0815-0796.

Discusses Eddy Nahmias' “Is Free Will an Illusion?”.

It is assumed that mental action, such as free will, exists, and an exploration is made of its relationship to the brain, physical laws, and evolutionary selection. If the assumption is made that all content of conscious experience is encoded in the brain, it follows that free will must act as process only. This result is consistent with the experimental results of Libet and others that if free will exists, it must act by making a selection between alternatives provided by (...) the brain. Also, proposals for some additional actions of consciousness, besides free will, are reviewed. The use of mental action by consciousness is not in accord with presently known physics, in which physical changes are either deterministic or random, and an extension would have to be made to known physics to account for physical changes produced by such an action. However, such an extension could be fairly simple in overview, such as the assumption that consciousness can produce the ordering of randomness. Examples of several such theories are given. If consciousness can make selections among programs in the brain/nervous system, and thereby contribute to the formation of behavior, less programming would be needed, especially in situations affected by a variety of types of factors. For this reason consciousness might be present early in the evolutionary line for animals that explore new territory. Emotions and cognitive ability, even though determined by the brain, could be viewed as “choice guiders,” and for this reason their presence in an animal would indicate the presence of consciousness. (shrink)

Two forms of independent action by consciousness have been proposed by various researchers – free will and holistic processing. (Holistic processing contributes to the formation of behavior through the holistic use of brain programs and encoding.) The well-known experiment of Libet et al. (1983) implies that if free will exists, its action must consist of making a selection among alternatives presented by the brain. As discussed herein, this result implies that any physical changes mind can produce in the brain are (...) very small, and this in turn implies that holistic processing would also act to select among brain programs. The latter process would contribute to flexibility of behavior, which would therefore be an indication of the possible presence of consciousness in an animal. Because locomotion requires response to varying and unpredictable conditions, the above conclusions support the idea that simple forms of consciousness appear very early in the evolutionary line of the animal kingdom.

In recent decades, with advances in the behavioral, cognitive, and neurosciences, the idea that patterns of human behavior may ultimately be due to factors beyond our conscious control has increasingly gained traction and renewed interest in the age-old problem of free will. In this book I examine both the traditional philosophical problems long associated with the question of free will, such as the relationship between determinism and free will, as well as recent experimental and theoretical work directly related to consciousness (...) and human agency. I argue that our best scientific theories indeed have the consequence that factors beyond our control produce all of the actions we perform and that because of this we do not possess the kind of free will required for genuine or ultimate responsibility. I further argue that the strong and pervasive belief in free will, which I consider an illusion, can be accounted for through a careful analysis of our phenomenology and a proper theoretical understanding of consciousness. Indeed, the primary goal of this book is to argue that our subjective feeling of freedom, as reflected in the first-person phenomenology of agentive experience, is an illusion created by certain aspects of our consciousness. So after working to establish that free will is an illusion in the early chapters, I then proceed to give a novel account of just how that illusion is created in the later chapters. I present my illusionist account using one leading theory of consciousness—the higher-order thought (or HOT) theory of consciousness. I maintain that by combining the theoretical framework of the HOT theory with empirical findings in the behavioral, cognitive, and neurosciences, we can come to see that the illusion of free will is created by the particular way our higher-order thoughts make us conscious of our mental states and how our sense of self is constructed within consciousness.

As neuroscience uncovers these and other mechanisms regulating choices and social behaviour, we cannot help but wonder whether anyone truly chooses anything (though see "Is the universe deterministic?"). As a result, profound questions about responsibility are inescapable, not just regarding criminal justice, but in the day-to-day business of life. Given that, I suggest that free will, as traditionally understood, needs modification. Because of its importance in society, any description of free will updated to fit what we know about the nervous (...) system must also reflect our social need for a working concept of responsibility.

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

Rose's Lifelines justifiably attacks the rigid genetic determinism that pervades the popular press and even some scientific writing. Genes do not equate with destiny. However, Rose's argument should not be taken too far: genes do influence behavior, in animals as well as in man.

This article considers the roles played by brain images (e.g., from PET scans) in mass media as experienced by people suffering from mental illness, and as used by scientists and activist groups in demonstrating a biological basis for mental illness. Examining the rhetorical presentation of images in magazines and books, the article describes the persuasive power that brain images have in altering the understanding people have of their own body—their objective self. Analyzing first-person accounts of encounters with brain images, it (...) argues that people come to understand themselves as having neurotransmitter imbalances that are the cause of their illnesses via received facts and images of the brain, but that this understanding is incomplete and in tension with the sense that they are their brain. The article concludes by querying the emergence of a pharmaceutical self, in which one experiences one's brain as if on drugs, as a new form of objective self-fashioning. (shrink)

Some practical criteria for free-will are suggested where free-will is a matter of degree. It is argued that these are more appropriate than some extremely idealised conceptions. Thus although the paper takes lessons from philosophy it avoids idealistic approaches as irrelevant. A mechanism for allowing an agent to meet these criteria is suggested: that of facilitating the gradual emergence of free-will in the brain via an internal evolutionary process. This meets the requirement that not only must the choice of action (...) be free but also choice in the method of choice, and choice in the method of choice of the method of choice etc. This is directly analogous to the emergence of life from non-life. Such an emergence of indeterminism with respect to the conditions of the agent fits well with the `Machiavellian Intelligence Hypothesis' which posits that our intelligence evolved (at least partially) to enable us to deal with social complexity and modelling `arms races'. There is a clear evolutionary advantage in being internally coherent in seeking to fulfil ones goals and unpredictable by ones peers. To fully achieve this vision several other aspects of cognition are necessary: open-ended strategy development; the meta-evolution of the evolutionary process; the facility to anticipate the results of strategies; and the situating of this process in a society of competitive peers. Finally the requirement that reports of the deliberations that lead to actions need to be socially acceptable leads to the suggestion that the language that the strategies are developed within be subject to a normative process in parallel with the development of free-will. An appendix outlines a philosophical position in support of my position. (shrink)

Many scientists believe that the universe, including the human brain, is governed by natural laws and that all can be explained by natural processes. In consequence, they believe that all events, including brain events, are determined. From this, they often conclude that free will cannot exist. I believe these views are mistaken and will present several lines of argument to support this position. I conclude that the operation of free will is compatible with determinism, can be explained by natural processes (...) and does not entail immaterial substance. (shrink)

In “Lifelines” Steven Rose constructs a case against neurogenetic determinism based on experimental data from biology and in favor of a significant degree of self determination. Two philosophical errors in the case favoring neurogenetic determinism are illustrated by Rose: category mistakes and an excessively narrow view of causality restricted to the linear form.

Some philosophers argue that Descartes was wrong when he characterized animals as purely physical automata – robots devoid of consciousness. It seems to them obvious that animals (tigers, lions, and bears, as well as chimps, dogs, and dolphins, and so forth) are conscious. There are other philosophers who argue that it is not beyond the realm of possibilities that robots and other artificial agents may someday be conscious – and it is certainly practical to take the intentional stance toward them (...) (the robots as well as the philosophers) even now. I'm not sure that there are philosophers who would deny consciousness to animals but affirm the possibility of consciousness in robots. In any case, and in whatever way these various philosophers define consciousness, the majority of them do attribute consciousness to humans. Amongst this group, however, there are philosophers and scientists who want to reaffirm the idea, explicated by Shadworth Holloway Hodgson in 1870, that in regard to action the presence of consciousness does not matter since it plays no causal role. Hodgson's brain generated the following thought: neural events form an autonomous causal chain that is independent of any accompanying conscious mental states. Consciousness is epiphenomenal, incapable of having any effect on the nervous system. James (1890, 130) summarizes the situation. (shrink)

Obsessive-compulsive disorder (OCD) and other psychiatric disorders can interfere with a person’s capacity to control the nature of his mental states and how they issue in his decisions and actions. Insofar as this sort of control is identified with free will, and psychiatric disorders can impair this control, these disorders can impair free will. The will can be compromised by dysregulated neural networks that disable the mental mechanisms necessary to regulate thought, motivation, and action. Neural and mental dys-function result in (...) the maladaptive and pathological behaviors associated with these disorders. In “Obsessive-Compulsive Disorder, Free Will, and Control,” Gerben Meynen (2012) rightly .. (shrink)

A BELIEF IN FREE WILL touches nearly everything that human beings value. It is difficult to think about law, politics, religion, public policy, intimate relationships, morality—as well as feelings of remorse or personal achievement—without first imagining that every person is the true source of his or her thoughts and actions. And yet the facts tell us that free will is an illusion. In this enlightening book, Sam Harris argues that this truth about the human mind does not undermine morality or (...) diminish the importance of social and political freedom, but it can and should change the way we think about some of the most important questions in life.

In the first two sections of the paper, some basic terminological distinctions regarding “freedom of the will” as a philosophical problem are expounded and discussed. On this basis, the third section focuses on the examination of two neurophysiological experiments (one by Benjamin Libet and one by William Grey Walter), which in recent times are often interpreted as providing an empirical vindication of determinism and, accordingly, a refutation of positions maintaining freedom of the will. It will be argued that both experiments (...) fall short in this respect, and that in general—for methodical reasons—the prospects of ever deciding the dispute about freedom of the will through empirical research are rather poor.

When laws or legal principles mention mental states such as intentions to form a contract, knowledge of risk, or purposely causing a death, what parts of the brain are they speaking about? We argue here that these principles are tacitly directed at our prefrontal executive processes. Our current best theories of consciousness portray it as a workspace in which executive processes operate, but what is important to the law is what is done with the workspace content rather than the content (...) itself. This makes executive processes more important to the law than consciousness, since they are responsible for channeling conscious decision-making into intentions and actions, or inhibiting action.We provide a summary of the current state of our knowledge about executive processes, which consists primarily of information about which portions of the prefrontal lobes perform which executive processes. Then we describe several examples in which legal principles can be understood as tacitly singling out executive processes, including principles regarding defendants’ intentions or plans to commit crimes and their awareness that certain facts are the case(for instance, that a gun is loaded), as well as excusatory principles which result in lesser responsibility for those who are juveniles, mentally ill, sleepwalking, hypnotized, or who suffer from psychopathy.

In this book, Hodgson presents a clear and compelling case against today's orthodox mechanistic view of the brain-mind, and in favor of the view that "the mind matters." In the course of the argument he ranges over such topics as consciousness, informal reasoning, computers, evolution, and quantum indeterminancy and non-locality. Although written from a philosophical viewpoint, the book has important implications for the sciences concerned with the brain-mind problem. At the same time, it is largely non-technical, and thus accessible to (...) the non-specialist reader. (shrink)

(I) John Searle's conception of consciousness in the 'Mind the Gap' issue of the Journal of Consciousness Studies remains short on content, no advance on either materialism or traditional dualism. Still, it is sufficiently contentful to be self-contradictory. And so his Biological Subjectivity on Two Levels, like materialism and dualism, needs replacing by a radically different conception of consciousness -- such as Consciousness as Existence. (II) From his idea that we can discover 'gaps', seeming absences of causal circumstances, in our (...) experience of deciding and acting, Searle is led to the positing of a self and to mysterious causing. (III) In fact philosophers of determinism and freedom over three centuries have concerned themselves with what are now termed 'gaps'. Searle's advance is a useful terminological one. Compatibilist philosophers of freedom, contrary to what is said, have not missed any point at all. A successor to both Compatibilism and Incompatibilism is needed. (IV) Searle's previous account of deciding and acting in Biological Subjectivity on Two Levels does indeed fail because of its epiphenomenalism. (V) The culmination of his paper, his preferred hypothesis now about deciding and acting, is that down-up causation is true of it but not left-right causation. Quantum Theory as often interpreted doesn't work down-up but does work left-right. The hypothesis is entirely in the tradition of the Incompatibilist and Libertarian philosophers of determinism and freedom, whom Searle has joined, but is factually incredible. (shrink)

Over the past few years, a number of authors in the new field of neuroethics have claimed that there is an ethical challenge presented by the likelihood that the findings of neuroscience will undermine many common assumptions about human agency and selfhood. These authors claim that neuroscience shows that human agents have no free will, and that our sense of being a “self” is an illusory construction of our brains. Furthermore, some commentators predict that our ethical practices of assigning moral (...) blame, or of recognizing others as persons rather than as objects, will change as a result of neuroscientific discoveries that debunk free will and the concept of the self. I contest suggestions that neuroscience’s conclusions about the illusory nature of free will and the self will cause significant change in our practices. I argue that we have self-interested reasons to resist allowing neuroscience to determine core beliefs about ourselves. (shrink)

Our aim in this paper is to raise a question about the relationship between theories of responsibility, on the one hand, and a commitment to conscious attitudes, on the other. Our question has rarely been raised previously. Among those who believe in the reality of human freedom, compatibilists have traditionally devoted their energies to providing an account that can avoid any commitment to the falsity of determinism while successfully accommodating a range of intuitive examples. Libertarians, in contrast, have aimed to (...) show that either physical indeterminacy or a certain kind of agent causation can find a place in the world for what they take to be genuine freedom. Few have considered whether moral responsibility requires a commitment to conscious attitudes.2 Our question derives from a confluence of two sources. First, there is reason to think that conscious attitudes matter to theories of responsibility, either directly, as a result of the latter’s commitments, or indirectly, by virtue of the assumptions that they make about certain intuitive examples. Second, there is accumulating evidence suggesting that there aren’t any conscious mental states possessing the sorts of causal roles required of propositional attitudes. Since theorists of responsibility should in general be concerned to make their views compatible with plausible claims about the natural world, the implications of this data should be carefully considered. Our aim is therefore to motivate and begin exploring answers to the following conditional question: If it should turn out that there are no conscious attitudes, then what would be the implications of this fact (if any) for theories of responsibility? We propose that theorists who aren’t skeptics about moral responsibility should examine their accounts, asking whether their theories (or the examples that motivate them) could survive the discovery that there are no conscious judgments, decisions, or evaluations. Since we take it that moral theorizing in general should operate with the weakest possible empirical assumptions about the natural world, such theorists should consider whether their accounts could be motivated in such a way as to be free of any commitment to the existence of conscious attitudes..

If you start taking courses in contemporary cognitive science, you will soon encounter a particular picture of the human mind. This picture says that the mind is a lot like a computer. Specifically, the mind is made up of certain states and certain processes. These states and processes interact, in accordance with certain general rules, to generate specific behaviors. If you want to know how those states and processes got there in the first place, the only answer is that they (...) arose through the interaction of other states and processes, which arose from others... until, ultimately, the chain goes back to factors in our genes and our environment. Hence, one can explain human behavior just by positing a collection of mental states and psychological processes and discussing the ways in which these states and processes interact. This picture of the mind sometimes leaves people feeling deeply uncomfortable. They find themselves thinking something like: 'If the mind actually does work like that, it seems like we could never truly be morally responsible for anything we did. After all, we would never be free to choose any behavior other than the one we actually performed. Our behaviors would just follow inevitably from certain facts about the configuration of the states and processes within us.' Many philosophers think that this sort of discomfort is fundamentally confused or wrongheaded. They think that the confusion here can be cleared up just by saying something like: 'Wait! It doesn't make any sense to say that the interaction of these states and processes is preventing you from controlling your own life. The thing you are forgetting is that the interaction of these states and processes – this whole complex system described by cognitive science – is simply you. So when you learn that these states and processes control your behavior, all you are learning is that you are controlling your behavior. There is no reason at all to see these discoveries as a threat to your freedom or responsibility.'2 Philosophers may regard this argument as a powerful one, perhaps even irrefutable.. (shrink)

Both libertarian and compatibilist approaches have been unsuccessful in providing an acceptable account of free will. Recent developments in cognitive neuroscience, including the connectionist theory of mind and empirical findings regarding modularity and integration of brain functions, provide the basis for a new approach: neural holism. This approach locates free will in fully integrated behavior in which all of a person's beliefs and desires, implicitly represented in the brain, automatically contribute to an act. Deliberation, the experience of volition, and cognitive (...) and behavioral shortcomings are easily understood under this model. Assigning moral praise and blame, often seen as grounded in the notion that a person has the ability to have done otherwise, will be shown to reflect instead important aspects of signaling in social interactions. Thus, important aspects of the traditional notion of free will can be accounted for within the proposed model, which has interesting implications for lifelong cognitive development. (shrink)

Abstract : Libet’s famous experiments, showing that apparently we become aware of our intention to act only after we have unconsciously formed it, have widely been taken to show that there is no such thing as free will. If we are not conscious of the formation of our intentions, many people think, we do not exercise the right kind of control over them. I argue that the claim this view presupposes, that only consciously initiated actions could be free, places a (...) condition upon freedom of action which it is in principle impossible to fulfil, for reasons that are conceptual and not merely contingent. Exercising this kind of control would require that we control our control system, which would simply cause the same problem to arise at a higher-level or initiate an infinite regress of controllings. If the unconscious initiation of actions, as well as the takings of decisions, is incompatible with control over them, then free will is impossible on conceptual grounds. Thus, Libet’s experiments do not constitute a separate, empirical, challenge to our freedom. (shrink)

Brain implants, such as Deep Brain Stimulation (DBS), which are designed to improve motor, mood and behavioural pathology, present unique challenges to our understanding of identity, agency and free will. This is because these devices can have visible effects on persons' physical and psychological properties yet are essentially undetectable when operating correctly. They can supplement and compensate for one's inherent abilities and faculties when they are compromised by neuropsychiatric disorders. Further, unlike talk therapy or pharmacological treatments, patients need not ‘do’ (...) anything for the treatment to take effect. If one accepts, as we argue here, that brain implants are unique among implantable types of devices, then this can have significant implications for what it means to persist as the same person and be the source of one's thoughts and actions. By examining two of the most common indications for DBS in current use, namely in the motor (Parkinson's Disease) and psychiatric (Major Depression) domains, we further argue that although DBS, as it is currently applied, does not necessarily represent a unique threat to personal identity and agency per se, it introduces an unprecedented ‘third party’ into the debate on these concepts. In this way, DBS can be used as a tool to begin probing, both conceptually and empirically, some of philosophy's most perennial metaphysical questions. (shrink)

Action is to be distinguished from (mere) bodily movement not by reference to an agent's intentions, or his conscious control of his movements (Sect. I), but by reference to the agent as cause of those movements, though this needs to be understood in a way which destroys the alleged distinction between agent-causation and event-causation (Sect. II). It also raises the question of the relation between an agent and his neurophysiology (Sect. III), and eventually the question of the compatibility of purposive (...) and mechanistic accounts of human behaviour (Sect. IV). For the two to be compatible it is necessary that, e.g., intentions and brain states be not merely co-existent but also causal equivalents, in a way which allows for the mechanical explanation of teleological states — or vice versa.

Many philosophers as well as many biological psychologists think that recent experiments in neuropsychology have definitively discredited any notion of freedom of the will. I argue that the arguments mounted against the concept of freedom of the will in the name of natural causal determinism are valuable but not new, and that they leave intact a concept of freedom of the will that is compatible with causal determinism. After explaining this concept, I argue that it is interestingly related to our (...) use of the first person pronoun “I.” I discuss three examples of our use of “I” in thought and language and submit a few questions I would like neuropsychologists to answer concerning the brain processes that might underlie those uses. I suggest answering these questions would support the compatibilist notion of freedom of the will I have offered in part 1 of the paper. (shrink)

Over the last 25 years, experimental findings published by Benjamin Libet have indicated that conscious acts of will are preceded by a characteristic kind of brain event of which the agent is not conscious. It, Libet says, rather than the will, is what causes actions. His discoveries, if correct, would seem to imply that the notion of a free, conscious will is an illusion, and that actions are initiated by neural processes not under conscious control. In what follows it is (...) argued that Libet’s conclusion is incorrect, and that other evidence points to the essential causal role of consciousness in voluntary action. (shrink)
