Do humans have a free choice of which actions to perform? Three recent developments of modern science can help us to answer this question. First, new investigative tools have enabled us to study the processes in our brains which accompanying our decisions. The pioneer work of Benjamin Libet has led many neuroscientists to hold the view that our conscious intentions do not cause our bodily movements but merely accompany them. Then, Quantum Theory suggests that not all physical events are fully determined by their causes, and so opens the possibility that not all brain events may be fully determined by their causes, and so maybe — if neuroscience does not rule this out — there is a role for intentions after all. Finally, a theorem of mathematics, Gödel's theory, has been interpreted to suggest that the initial conditions and laws of development of a mathematician's brain could not fully determine which mathematical conjectures he sees to be true. The extent to which human behaviour is determined by brain events may well depend on whether conscious events, such as intentions, are themselves merely brain events, or whether they are separate events which interact with brain events (perhaps in the radical form that intentions are events in our soul, and not in our body). This book considers what kind of free will we need in order to be morally responsible for our actions or be held guilty in a court of law. Is it sufficient merely that our actions are uncaused by brain events?Less

This chapter examines what is arguably the most influential rebutting objection in the current literature, an objection that appeals to Benjamin Libet's studies concerning the neural basis of agency. Although Libet himself stopped short of endorsing free will scepticism on the basis of his results, other theorists have not been so cautious, and his work is often said to show that we lack free will. It is argued that Libet's findings show no such thing. However, Libet's experiments do raise a number of interesting and important questions for accounts of free will. In particular, Libet's experiments raise challenging questions about the analysis of the concept of free will. In order to determine whether brain science supports free will scepticism we need not only to understand the relevant brain science, we also need to understand just what the common-sense or folk notion of free will commits us to. The latter requirement may be as difficult to meet as the former one is.Less

This book has both a negative aim and a positive aim. The negative aim is to show that some recent influential scientific claims about free will, consciousness, and action‐production are not warranted by the data. These claims (by Benjamin Libet, Daniel Wegner, and others) include the following: your brain routinely decides what you will do before you become conscious of its decision; there is only a 100‐millisecond window of opportunity for free will, and all you can freely do in that window is veto conscious intentions that you were about to execute; intentions and their physical correlates play no role in producing corresponding actions; and free will is an illusion. The positive aim is to show that there is powerful empirical support for the thesis that there are effective conscious decisions and intentions to act.Less

This chapter is a commentary on the others, concentrating on themes that link many of them. It provides conceptual background on free will, distinguishes among distinct philosophical positions on the topic (including compatibilist and incompatibilist positions), discusses determinism and laws of nature, connects free will to consciousness, critically examines Benjamin Libet's work on free will and consciousness, and considers the light that Daniel Wegner's contribution to the volume sheds on the “the illusion of conscious will” and free will.Less

This chapter analyzes how Libet's experiments bear on criminal and moral responsibility. More specifically, it addresses the question of whether Libet has demonstrated that the consciously willed bodily movement, the centerpiece of our notions of criminal and moral responsibility, is an illusion. It suggests that the gatekeeper role for conscious will, which Libet allows, does not require any revision of traditional notions of moral and criminal responsibility.Less

This chapter examines the neuroscientific challenges stemming from the kind of experiments begun in the early 1980s by Benjamin Libet and his associates. It argues that Libet's work is philosophically challenged rather than challenging. According to Libet's own characterizations of his challenges to the folk psychology: “If the ‘act now’ process is initiated unconsciously, then conscious free will is not doing it.” Three things run together in the phrase, “conscious free will”: firstly, maybe a conscious will is initiating action, but it isn't a free will doing the work; secondly, maybe there is consciousness and freedom at the time of action initiation, but there is no will doing any action initiation; and thirdly, maybe there is a free will operating to initiate actions, but there is no consciousness of that will or its operations at the time it is initiating actions. The chapter shows that Libet elided these three distinct challenges together.Less

This chapter reviews Libet's main claims, and the implications he drew from them about free will and responsibility. It considers first whether, on the supposition that the claims are correct, the empirical interpretations that Libet and many since have gleaned from his data really are warranted. It then addresses whether his empirical claims really have the implications he thinks they have for free will. It is argued that neither Libet's data nor the reasoning that follows strongly support the fairly radical claims about free will that many have supposed.Less

We all seem to think that we do the acts we do because we consciously choose to do them. This commonsense view is thrown into dispute by Benjamin Libet's eyebrow-raising experiments, which seem to suggest that conscious will occurs not before but after the start of brain activity that produces physical action. Libet's striking results are often claimed to undermine traditional views of free will and moral responsibility, and to have practical implications for criminal justice. His work has also stimulated a flurry of further fascinating scientific research—including findings in psychology by Dan Wegner and in neuroscience by John–Dylan Haynes—that raises novel questions about whether conscious will plays any causal role in action. Critics respond that both commonsense views of action and traditional theories of moral and legal responsibility, as well as free will, can survive the scientific onslaught of Libet and his progeny. To further this lively debate, this book discusses whether our conscious choices really cause our actions, and what the answers to that question mean for how we view ourselves and how we should treat each other.Less

The real question that Libet's experiments raise is whether our conscious wills cause the willed actions. What is at issue is the effects rather than the causes of conscious will. The question is whether conscious will is impotent, not whether it is free. If conscious will is impotent, then we cannot control our actions by means of conscious will, and this disability might reduce our freedom of action. Libet's experiments raises or sharpens this new question. By raising a new issue in a new way, Libet's work made (and continues to make) many people rethink their assumptions. The assumptions at stake are both normative and descriptive. The relevant normative assumption is, roughly, that causation by conscious will is necessary for responsibility. The descriptive assumption that Libet questions is, again roughly, that conscious will causes the willed action. This chapter addresses these assumptions in turn. It concludes that Libet's experiments do not undermine responsibility in general, but they do illuminate some particular cases as well as common standards of responsibility.Less

This chapter presents a classic essay in which Benjamin Libet lays out his basic experimental results and draws philosophical lessons regarding free will and responsibility. He argues that the existence of free will is at least as good, if not a better, scientific option than is its denial by determinist theory. Given the speculative nature of both determinist and nondeterminist theories, why not adopt the view that we do have free will (until some real contradictory evidence may appear, if it ever does). Such a view would at least allow us to proceed in a way that accepts and accommodates our own deep feeling that we do have free will. We would not need to view ourselves as machines that act in a manner completely controlled by the known physical laws. Such a permissive option has also been advocated by the neurobiologist Roger Sperry.Less

This chapter focuses on the phenomenal character of agentive experience—i.e., what it is like to experience oneself as the conscious author of one's behavior. Experiences with this distinctive kind of “what-it's-like-ness,” have representational content—i.e., they represent oneself, to oneself, as willfully generating one's actions. This chapter argues that the representational content of act-commencement experience, as determined by the phenomenal character of such experience, is quite compatible with the possibility that action-triggering neural activity in the motor cortex is already occurring at a point in time prior to the onset of the experience of conscious act-commencement; hence, even if one were to grant that the work of Libet and others really does establish that the acts experienced as willfully produced are causally initiated by brain-events that occur prior to the experienced onset of act-commencement, this presumptive fact would not show that the experience of conscious will is an illusion.Less

Libet's data show that EEG readiness potentials begin before the urge to move is consciously felt. This result has been widely interpreted as showing that spontaneous voluntary movements are initiated preconsciously. This chapter reports two new findings relevant to this conclusion. First, the question of whether readiness potentials (RPs) are precursors of movement per se or merely indicators of general readiness has always been moot. On the basis of both new experimental evidence and an inspection of the literature, it is argued that Libet's type II RPs 1 are neither necessary nor sufficient for spontaneous voluntary movement. Secondly, it argues that RPs often do not occur at all before movements initiated as a result of decisions, as opposed to spontaneous urges. When RPs do occur before decision-based movements, they are much shorter than urge-related RPs, and usually start at the same time as or slightly after the reported decision times. Thus, even if this third, shorter type of RP could be considered to relate specifically to movement rather than to general readiness, movements resulting from conscious decisions (as opposed to spontaneous urges) are unlikely to be initiated preconsciously.Less

Whereas the traditional free will debate focused on the free part of “free will”—with an emphasis on alternative possibilities and the ability to do otherwise—many of the new threats from psychology pose potential problems for the will part as well. This chapter attempts to shed some light on the nature of these potential psychological threats. It first sets the stage by explaining and clarifying some key terms and exploring some of the key issues from the free will debate. It then examines several potential threats to free will collectively referred to as the Threat of Shrinking Agency. In piecing this general threat together, it discusses the work of several prominent psychologists including Jonathan Bargh, Benjamin Libet, Daniel Wegner, and others. The goal is not to argue that these threats actually do undermine free will and responsibility, but simply to trace the boundaries of the potential threats examined and show that they are not dependent on other potential threats such as determinism, mechanism, reductionism, and the like.Less

This chapter examines the concepts that inform the recent experimental studies of intentional action. Drawing on a distinction between unconscious urge and conscious decision, it argues that the neural activity reported by Benjamin Libet may represent an urge to move rather than a decision to do so, and that the decision to move might be made only when the subject becomes conscious of the urge. In this case, Libet’s experiments do not threaten free will. The chapter describes two competing theories about the nature of free will and suggests that Libet’s results do not support his contention that “the brain decides to initiate or, at least, to prepare to initiate the act before there is any reportable subjective awareness that such a decision has taken place”.Less

This chapter describes an experiment designed to time the thought (T) of movement without relying on introspective data or retrospective reconstruction. It shows that T occurred later than observable brain events linked to action. The results also suggest that there is not enough time to veto action after willing becomes conscious, contrary to Libet's way of saving free will.Less
