Robert Kane provides a critical overview of debates about free will of the past half century, relating this recent inquiry to the broader history of the free will issue and to vital currents of twentieth century thought. Kane also defends a traditional libertarian or incompatibilist view of free will, employing arguments that are both new to philosophy and that respond to contemporary developments in physics and biology, neuro science, and the cognitive and behavioral sciences.

A fundamental assumption of theories of decision-making is that we detect mismatches between intention and outcome, adjust our behavior in the face of error, and adapt to changing circumstances. Is this always the case? We investigated the relation between intention, choice, and introspection. Participants made choices between presented face pairs on the basis of attractiveness, while we covertly manipulated the relationship between choice and outcome that they experienced. Participants failed to notice conspicuous mismatches between their intended choice and the outcome (...) they were presented with, while nevertheless offering introspectively derived reasons for why they chose the way they did. We call this effect choice blindness. (shrink)

Reviews evidence which suggests that there may be little or no direct introspective access to higher order cognitive processes. Ss are sometimes unaware of the existence of a stimulus that importantly influenced a response, unaware of the existence of the response, and unaware that the stimulus has affected the response. It is proposed that when people attempt to report on their cognitive processes, that is, on the processes mediating the effects of a stimulus on a response, they do not do (...) so on the basis of any true introspection. Instead, their reports are based on a priori, implicit causal theories, or judgments about the extent to which a particular stimulus is a plausible cause of a given response. This suggests that though people may not be able to observe directly their cognitive processes, they will sometimes be able to report accurately about them. Accurate reports will occur when influential stimuli are salient and are plausible causes of the responses they produce, and will not occur when stimuli are not salient or are not plausible causes.

Voluntary acts are preceded by electrophysiological (RPs). With spontaneous acts involving no preplanning, the main negative RP shift begins at about200 ms. Control experiments, in which a skin stimulus was timed (S), helped evaluate each subject's error in reporting the clock times for awareness of any perceived event.

I have taken an experimental approach to this question. Freely voluntary acts are preceded by a specific electrical change in the brain that begins 550 ms before the act. Human subjects became aware of intention to act 350-400 ms after RP starts, but 200 ms. before the motor act. The volitional process is therefore initiated unconsciously. But the conscious function could still control the outcome; it can veto the act. Free will is therefore not excluded. These findings put constraints on (...) views of how free will may operate; it would not initiate a voluntary act but it could control performance of the act. The findings also affect views of guilt and responsibility. But the deeper question still remains: Are freely voluntary acts subject to macro-deterministic laws or can they appear without such constraints, non-determined by natural laws and ‘truly free'? I shall present an experimentalist view about these fundamental philosophical opposites. (shrink)

This paper responds to three critical essays on my book, The Significance of Free Will(Oxford, 1996) by Randolph Clarke, Istiyaque Haji and Alfred Mele (which essays appear in this issue and an earlier issue of this journal). This response first explains crucial features of the theory of free will of the book, including the notion of ultimate responsibility.The paper then answers objections of Haji and Mele that the occurrence of undetermined choices would be matters of luck or chance, and so (...) could not be responsible actions. It then responds to concerns of Clarke that indeterminism provides no greater degree of control for defenders of incompatibilist free will and to concerns Clarke has about the notions of "effort" and "willing" in the book. Finally, the paper addresses objections of Haji concerning Frankfurt type-examples and the relation of moral responsibility to the power to act otherwise, and it addresses a concern of Mele's about why we should want a free will that is incompatible with determinism.

It is my view that one essential difference between persons and other creatures is to be found in the structure of a person's will. Besides wanting and choosing and being moved to do this or that, men may also want to have certain desires and motives. They are capable of wanting to be different, in their preferences and purposes, from what they are. Many animals appear to have the capacity for what I shall call "first-order desires" or "desires of the (...) first order," which are simply desires to do or not to do one thing or another. No animal other than man, however, appears to have the capacity for reflective self-evaluation that is manifested in the formation of second-order desires. (shrink)

The chief goal of Velmans' article is to find a way to solve the problem of how conscious experience could have bodily effects. I shall discuss his treatment of this below. First, I would like to deal with Velmans' treatment of my own studies of volition and free will in relation to brain processes. Unconscious Initiation and Conscious Veto of Freely Voluntary Acts Velmans appropriately refers to our experimental study that found that onset of an electrically observable cerebral process preceded (...) the appearance of the subject's awareness of the conscious wish to act, by at least 350 msec. That indicated that the volitional process is initiated unconsciously. Velmans uses the term preconscious instead of unconscious. But, in fact, subjects have no reportable awareness or intuitive feeling that the brain has started a process before their conscious wish/urge to act appears. Unconscious initiation of the voluntary process appeared to mean that conscious free will could not actually 'tell' the brain to begin its preparation to carry out a voluntary act. (shrink)

Consider the following principle: (LP) If an action is undetermined at a time t, then its happening rather than not happening at t would be a matter of chance or luck, and so it could not be a free and responsible action. This principle (which we may call the luck principle, or simply LP) is false, as I shall explain shortly. Yet it seems true.

The mysteries of consciousness have gripped the human imagination for over 2,500 years. At the dawn of the new millennium, Understanding Consciousness provides new solutions to some of the deepest puzzles surrounding its nature and function. Drawing on recent scientific discoveries, Max Velmans challenges conventional reductionist thought, providing an understanding of how consciousness relates to the brain and physical world that is neither dualist, nor reductionist. Understanding Consciousness will be of great interest to psychologists, philosophers, neuroscientists and other professionals concerned (...) with mind/body relationships, and all who care deeply about this subject.

In this book Daniel Wegner offers a novel understanding of the relation of consciousness, the will, and our intentional and voluntary actions. Wegner claims that our experience and common sense view according to which we can influence our behavior roughly the way we experience that we do it is an illusion.

If the notion of free will is to be retained by philosophers, psychiatrists and psychologists, then it will be a free will which is essentially non-conscious. The purpose of this paper is to demonstrate that a conscious free will (in the sense of consciousness initiating action) is incompatible with the evidence of neuroscience, and the phenomenology described in the literature of normal creativity, psychotic passivity, and the neurological syndrome of the alien limb or hand. In particular the work of Libet (...) and others who have directly stimulated the brain and measured activity from its surface leads to the conclusion that subjective states (be they sensory or intentional) are preceded by predictive neural activity. Subjective phenomenology is temporally distinct from the initiation of “voluntary” action. In addition it will be argued that free will is more than a belief and that it comprises a perceptual sensorimotor component. Free will is conceptualized as a three component phenomenon consisting of a perceptual, non-linguistic experience of freedom, an experiential belief which is linguistic, and related to a specified action in time, and an abstract belief which is linguistic but remote from any particular action and akin to philosophical discourse (the abstract belief or otherwise, in free will). A theoretical explanation of some of the pathological phenomenology of possession of action is offered in terms of temporal considerations. The direction of action within mental/virtual space is hypothesized to be a function of the temporal sequence of its initiation and awareness of the latter “reaching” consciousness. It is suggested that perturbation of this temporal sequence may lead to the misattribution of host-as-alien-initiated action. Work of this kind, which is beyond subjective introspection, is necessary if we are to develop adequate models to use in conjunction with modern investigation techniques. (shrink)

Mental timing studies may be influenced by powerful cognitive illusions that can produce an asymmetry in their rate of progress relative to neuronal timing studies. Both types of timing research are also governed by a temporal asymmetry, expressed by the fact that the direction of causation must follow time's arrow. Here we refresh our earlier suggestion that the temporal asymmetry offers promise as a means of timing mental activities. We update our earlier analysis of Libet's data within this framework. Then (...) we consider the surprises which often occur on those rare occasions when neural timing experiments parallel mental timing work exactly. Together, these surprises and asymmetries prescribe a relentlessly meticulous and fully transparent exposition of timing methods, terms, and concepts which shuns plausible narratives, even when buttressed by rigorous formal models, unless guided by apposite empirical evidence.
