  1. Libet-Style Experiments, Neuroscience, and Libertarian Free Will.Marcelo Fischborn - 2016 - Philosophical Psychology 29 (4):494-502.
    People have disagreed on the significance of Libet-style experiments for discussions about free will. In what specifically concerns free will in a libertarian sense, some argue that Libet-style experiments pose a threat to its existence by providing support to the claim that decisions are determined by unconscious brain events. Others disagree by claiming that determinism, in a sense that conflicts with libertarian free will, cannot be established by sciences other than fundamental physics. This paper rejects both positions. First, (...)

  2. The Interpretation of Libet's Results on the Timing of Conscious Events: A Commentary.Gilberto Gomes - 2002 - Consciousness and Cognition 11 (2):221-230.
    A commentary on articles by Klein, Pockett, and Trevena and Miller, in this issue, is given. Average shift in the point of subjective equality , calculated by Klein on Libet's data, and corresponding change in mean shift, calculated by Libet et al. , may be “corrected,” taking as a reference point the end of the minimum train duration. Values obtained, if significant, indicate a latency for conscious sensation of the skin stimulus of at least 230 ms. Pockett's main (...)

  3. The Timing of Conscious Experience: A Critical Review and Reinterpretation of Libet's Research.Gilberto Gomes - 1998 - Consciousness and Cognition 7 (4):559-595.
    An extended examination of Libet's works led to a comprehensive reinterpretation of his results. According to this reinterpretation, the Minimum Train Duration of electrical brain stimulation should be considered as the time needed to create a brain stimulus efficient for producing conscious sensation and not as a basis for inferring the latency for conscious sensation of peripheral origin. Latency for conscious sensation with brain stimulation may occurafterthe Minimum Train Duration. Backward masking with cortical stimuli suggests a 125-300 ms minimum (...)

  4. Libet and Freedom in a Mind-Haunted World.David Gordon Limbaugh & Robert Kelly - 2018 - American Journal of Bioethics Neuroscience 9 (1):42-44.
    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 (...)

    There are numerous theoretical reasons which are usually said to undermine the case for mental causation. But in recent years, Libet‘s experiment on readiness potentials (Libet, Wright, and Gleason 1982; Libet, Gleason, Wright, and Pearl 1983), and a more recent replication by a research team led by John Dylan Haynes (Soon, C.S., Brass, M., Heinze, H.J., and Haynes, J.-D. [2008]) are often singled out because they appear to demonstrate empirically that consciousness is not causally involved in our (...)

Campis - 2008 - In Hannes Leitgeb & Alexander Hieke (eds.), Reduction and Elimination in Philosophy and the Sciences: Papers of the 31st International Wittgenstein Symposium. Austrian Ludwig Wittgenstein Society.
    In this paper we analyze Libet’s conclusions on «free will» (FW), rejecting his view of the concept and defending a partially aligned view with Wittgenstein’s early remarks on FW. First, the concept of Readiness Potential (RP) and Libet’s view are presented. Second, we offer an account of Wittgenstein´s point of view. Third, a dual-domain analysis is proposed; finally, we offer our conclusions. This article´s conclusions are part of an ongoing research.

  9. "Mind Time: The Temporal Factor in Consciousness" by Benjamin Libet[REVIEW]Tim Crane - 2007 - The Times Literary Supplement 1.
    After a lecture in Göteborg by the neuroscientist Benjamin Libet in 1993, the Göteborg-Post carried the headline, ‘Now it has been proven: we are all somewhat behind’. The paper was referring to Libet’s celebrated discovery that the neural precursors of some voluntary actions occur before the conscious awareness of the decision to act. In a series of experiments in the 1980s, Libet showed that in an experimental situation in which subjects were asked to perform a simple voluntary (...)

  10. The Neuroscientific Study of Free Will: A Diagnosis of the Controversy.Markus E. Schlosser - 2014 - Synthese 191 (2):245-262.
    Benjamin Libet’s work paved the way for the neuroscientific study of free will. Other scientists have praised this research as groundbreaking. In philosophy, the reception has been more negative, often even dismissive. First, I will propose a diagnosis of this striking discrepancy. I will suggest that the experiments seem irrelevant, from the perspective of philosophy, due to the way in which they operationalize free will. In particular, I will argue that this operational definition does not capture free will properly (...)

    1. Introduction The readiness potential was found to precede voluntary acts by about half a second or more (Kornhuber & Deecke, 1965). Kornhuber (1984) discussed the readiness potential in terms of volition, arguing that it is not the manifestation of an attentional processes. Libet discussed it in relation to consciousness and to free will (Libet et al. 1983a; 1983b; Libet, 1985, 1992, 1993). Libet asked the following questions. Are voluntary acts initiated by a conscious decision to (...)

    Benjamin Libet's empirical challenge to free will has received a great deal of attention and criticism. A standard line of response has emerged that many take to be decisive against Libet's challenge. In the first part of this paper, I will argue that this standard response fails to put the challenge to rest. It fails, in particular, to address a recent follow-up experiment that raises a similar worry about free will (Soon, Brass, Heinze, & Haynes, 2008). In the (...)

  14. Contribution à la Théorie de la Conscience, Conçue comme Activite du Cerveau.Gilberto Gomes - 1998 - Dissertation, Université Paris 7
    This thesis explores the possibility of theoretically conceiving consciousness as an activity of the brain. Objections, based on the concept of qualia, to the identification of consciousness with a brain activity are refuted. Phenomenal consciousness is identified with access-consciousness. Consciousness is conceived as a higher order processing of informational states of the brain. The state of consciousness represents an integration of prior nonconscious states. Libet’s research on the timing of conscious experience is reviewed and analyzed. His hypothesis of backward (...)

    Scientific experiments which try to examine free will are faced with various critical arguments — both philosophical and methodological. In this article I will present the most important and the most interesting critical arguments attacking two the most influential experiments: Benjamin Libet experiment and John‐Dylan Haynes experiment.

    The Problem of Determinism - Freedom as Self-Determination.Dieter Wandschneider - 2010 - Psychotherapie Forum 18:100-107.
    There are arguments for determinism. Admittedly, this is opposed by the fact of everyday experience of autonomy. In the following, it is argued for the compatibility of determinism and autonomy. Taking up considerations of Donald MacKay, a fatalistic attitude can be refuted as false. Repeatedly, attempts have been made to defend the possibility of autonomy with reference to quantum physical indeterminacy. But its statistical randomness clearly misses the meaning of autonomy. What is decisive, on the other hand, is the possibility (...)

  17. The Idea of Will.M. M. Dorenbosch - 2015 - Journal of Consciousness Exploration and Research 6 (7):449-472.
    This article presents a new conceptual view on the conscious will. This new concept approaches our will from the perspective of the requirements of our neural-muscular system and not from our anthropocentric perspective. This approach not only repositions the will at the core of behavior control, it also integrates the studies of Libet and Wegner, which seem to support the opposite. The will does not return as an instrument we use to steer, but rather as part of the way (...)

  18. What Does the Mind Do That the Brain Does Not?Jean E. Burns - 2010 - In R. L. Amoroso (ed.), The Complementarity of Mind and Body: Fulfilling the Dream of Descartes, Einstein and Eccles. Nova Science.
    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 (...)

    As philosophical and scientific arguments for free will skepticism continue to gain traction, we are likely to see a fundamental shift in the way people think about free will and moral responsibility. Such shifts raise important practical and existential concerns: What if we came to disbelieve in free will? What would this mean for our interpersonal relationships, society, morality, meaning, and the law? What would it do to our standing as human beings? Would it cause nihilism and despair as some (...)

    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 (...)

  22. On Experimental and Philosophical Investigations of Mental Timing: A Response to Commentary.Gilberto Gomes - 2002 - Consciousness and Cognition 11 (2):304-307.
    Reinterpretations of Libet's results have received support from most commentaries. Libet's arguments against alternative hypotheses are contested. Latency depends on intensity. Integration of intensity and duration explains the Minimum Train Duration. Analogies of Libet's timing of intentions with control experiments indicate biases of opposite signs, according to intramodal or intermodal results. Rosenthal's view of nonconscious intentions becoming conscious after a delay is favored. Compatibilist free will is discussed.

  23. “Local Determination”, Even If We Could Find It, Does Not Challenge Free Will: Commentary on Marcelo Fischborn.Adina Roskies & Eddy Nahmias - 2017 - Philosophical Psychology 30 (1-2):185-197.
    Marcelo Fischborn discusses the significance of neuroscience for debates about free will. Although he concedes that, to date, Libet-style experiments have failed to threaten “libertarian free will”, he argues that, in principle, neuroscience and psychology could do so by supporting local determinism. We argue that, in principle, Libet-style experiments cannot succeed in disproving or even establishing serious doubt about libertarian free will. First, we contend that “local determination”, as Fischborn outlines it, is not a coherent concept. Moreover, determinism (...)

    Empirical evidence, it has often been argued, undermines our commonsense assumptions concerning the efficacy of conscious intentions. One of the most influential advocates of this challenge has been Daniel Wegner, who has presented an impressive amount of evidence in support of a model of "apparent mental causation". According to Wegner, this model provides the best explanation of numerous curious and pathological cases of behavior. Further, it seems that Benjamin Libet's classic experiment on the initiation of action and the empirical (...)

    Neuroscience investigates how neuronal processing circuits work, but it has problems explaining experiences this way. For example, it hasn’t explained how colour and shape circuits bind together in visual processing, nor why colours and other qualia are experienced so differently yet processed by circuits so similarly, nor how to get from processing circuits to pictorial images spread across inner space. Some theorists turn from these circuits to their electromagnetic fields to deal with such difficulties concerning the mind’s qualia, unity, privacy, (...)

Neil Levy’s new work is a candidate for this latter purpose for the field.

    In this article we study the question of free will from an interdisciplinary angle, drawing on philosophy, neurobiology and physics. We start by reviewing relevant neurobiological findings on the functioning of the brain, notably as presented in (Koch 2009); we assess these against the physics of (in)determinism. These biophysics findings seem to indicate that neuronal processes are not quantum but classical in nature. We conclude from this that there is little support for the existence of an immaterial ‘mind’, capable of (...)

    This paper seeks to explain and evaluate, by an analytic method, the conflict between determinism and free will from the viewpoint of two physicalist reductionist philosophers, namely, Daniel Dennett and Sam Harris. Dennett is a compatibilist philosopher who tries to show compatibility between determinism and free will, while Sam Harris is a non-compatibilist philosopher who turns to determinism with the thesis that our thoughts and actions have been pre-determined by the neurobiological events associated with them, and thus, considers free will (...)

    Foundation of All Axioms the Axioms of Consciousness (Consciousness and Special Relativity?).Frank de Silva - 1996 - Engineering in Medicine and Biology 15 (3):21-26.
    A description of consciousness leads to a contradiction with the postulation from special relativity that there can be no connections between simultaneous event. This contradiction points to consciousness involving quantum level mechanisms. The Quantum level description of the universe is re- evaluated in the light of what is observed in consciousness namely 4 Dimensional objects. A new improved interpretation of Quantum level observations is introduced. From this vantage point the following axioms of consciousness is presented. Consciousness consists of two distinct (...)

    A Framework for Conscious Information Processing.Balaram Das - manuscript
    This paper exploits the fact that the variability in the inter-spike intervals, in the spike train issuing from a neuron, carries substantial information regarding the input to the neuron. A framework for neuronal information processing is proposed which utilizes the above fact to distinguish phenomenal from non-phenomenal mental representation. In the process, an explanation is offered as to what is it, in the nature of conscious mental states, that imparts them a subjective feeling – there is something it is like (...)

    The problem of free will is deeply linked with the causal relevance of mental events. The causal exclusion argument claims that, in order to be causally relevant, mental events must be identical to physical events. However, Gibb has recently criticized it, suggesting that mental events are causally relevant as double preventers. For Gibb, mental events enable physical effects to take place by preventing other mental events from preventing a behaviour to take place. The role of mental double preventers is hence (...)

    This paper presents what the authors call the ‘divergence problem’ regarding choosing between different future possibilities. As is discussed in the first half, the central issue of the problem is the difficulty of temporally locating the ‘active cause’ on the modal divergent diagram. In the second half of this paper, we discuss the ‘second-person freedom’ which is, strictly, neither compatibilist negative freedom nor incompatibilist positive freedom. The divergence problem leads us to two hypothetical views (i.e. the view of single-line determination (...)

    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 (...)
