Readiness potentials driven by non-motoric processes

An increase in brain activity known as the “readiness potential” (RP) can be seen over central scalp locations in the seconds leading up to a volitionally timed movement. This activity precedes awareness of the ensuing movement by as much as two seconds and has been hypothesized to reflect preconscious planning and/or preparation of the movement. Using a novel experimental design, we teased apart the relative contribution of motor-related and non-motor-related processes to the RP. The results of our experiment reveal that robust RPs occured in the absence of movement and that motor-related processes did not significantly modulate the RP. This suggests that the RP measured here is unlikely to reflect preconscious motor planning or preparation of an ensuing movement, and instead may reflect decision-related or anticipatory processes that are non-motoric in nature.     

Schopenhauer on the aimlessness of the will

Schopenhauer asserts that ‘the will, which is objectified in human life as it is in every appearance, is a striving without aim and without end’. The article rejects some recent readings of this claim, and offers the following positive interpretation: however many specific aims of my specific desires I manage to attain, none is a final aim, in the sense that none terminates my ‘willing as a whole’, none turns me into a non-willing being. To understand Schopenhauer’s claim we must recognize his central contrast between happiness and will-lessness. Happiness is the satisfaction of individual desire, but no act of will that succeeds in satisfying individual desire is the attainment of a final aim, in that none brings about a conscious state in which the subject experiences no more unfulfilled desires. Such a state is the ultimate goal of existence, in Schopenhauer’s view, but happiness does not provide a route along which it can be attained.     

Incompatibilism proved

The consequence argument attempts to show that incompatibilism is true by showing that if there is determinism, then we never had, have or will have any choice about anything. Much of the debate on the consequence argument has focused on the “beta” transfer principle, and its improvements. We shall show that on an appropriate definition of “never have had, have or will have any choice”, a version of the beta principle is a theorem given one plausible axiom for counterfactuals (weakening). Instead of being about transfer principles, the debate should be over whether the distant past and laws are up to us.     

Objections and replies within the fifth meditation

Malebranche held that God acts only by general volitions and so is not constantly interfering in the world. The content of God's volitions appears to include the general laws of nature and the particular initial configuration of the created world, so that occasional or natural causes have an important explanatory role. It is clear that at the least Malebranche meant by a ‘general volition’ the willing of events which followed general laws. Steven Nadler argued that this is all we should understand by a ‘general volition’, and so we should think that general volitions are simply particular volitions which follow a general law.

I argue that this view is not the correct interpretation of Malebranche's general volitions, for it does not do justice to the theological doctrine of the Treatise, masks the genuine difference between Arnauld and Malebranche, and conflicts with what Malebranche says about practical volitions. I then argue that despite Malebranche's view of general volitions, there is still an important difference between his view and Leibniz's.     

Free will and moral responsibility: does either require the other?

This article explores the conceptual connections between free action and action for which the agent is morally responsible. Questions addressed include the following. Can agents who are never morally responsible for anything sometimes act freely? Can agents who never act freely be morally responsible for some of their actions? Various compatibilist and incompatibilist responses to these questions are discussed, as is the control over their behavior that ordinary agents attribute to themselves.     

Nietzsche on the health of the soul

Abstract

Health (particularly of the soul [Seele]) is a central concept in Nietzsche’s work. Yet in the most philosophically sophisticated secondary literature on Nietzsche, there has been fairly little sustained treatment of just what Nietzschean health consists in. In this paper, I aim to provide an account of some of the central marks of this health: resilience, discipline, vitality, a certain positive condition of the will to power, a certain tendency toward integration, and so on. This exposition and discussion will be the main task of the paper. Then in the concluding section of the paper, I consider a line taken in some related secondary literature, which would suggest that health might ultimately be understood in formal or dynamic terms, relating to one’s will to power and/or the unity of one’s drives. I will present the beginnings of an argument against such an account of health. In focusing on the formal and dynamic side exclusively, it cannot get the full story. In particular, it seems to me to miss the substantive dimension that is essential if we are to understand health properly. As I shall suggest, the core concept of Nietzschean health is not fully explicable except by reference to normative terms.     

Effects of Manipulation on Attributions of Causation,Free Will,and Moral Responsibility

If someone brings about an outcome without intending to, is she causally and morally responsible for it? What if she acts intentionally, but as the result of manipulation by another agent? Previous research has shown that an agent's mental states can affect attributions of causal and moral responsibility to that agent , but little is known about what effect one agent's mental states can have on attributions to another agent. In Experiment 1, we replicate findings that manipulation lowers attributions of responsibility to manipulated agents. Experiments 2–7 isolate which features of manipulation drive this effect, a crucial issue for both philosophical debates about free will and attributions of responsibility in situations involving social influence more generally. Our results suggest that “bypassing” a manipulated agent's mental states generates the greatest reduction in responsibility, and we explain our results in terms of the effects that one agent's mental states can have on the counterfactual relations between another agent and an outcome.     

PASTORAL COUNSEL FOR THE ANXIOUS NATURALIST: DANIEL DENNETT'S FREEDOM EVOLVES

Abstract: Daniel Dennett's Freedom Evolves is a rhetorically powerful but philosophically unconvincing attempt to show that a deterministic and ontologically reductionist, but epistemologically pluralist, outlook may peacefully coexist with a robust acceptance of human freedom and moral responsibility. The key to understanding the harmony rests in recognizing that freedom is not a metaphysical or physical condition but is instead a product of deeply embedded social practices. I argue that Dennett's project rests on an unargued and implausible deflationary stance toward basic metaphysics.     

COMPATIBILISM EVOLVES?: ON SOME VARIETIES OF DENNETT WORTH WANTING

Abstract: I examine the extent to which Dennett's account in Freedom Evolves might be construed as revisionist about free will or should instead be understood as a more traditional kind of compatibilism. I also consider Dennett's views about philosophical work on free agency and its relationship to scientific inquiry, and I argue that extant philosophical work is more relevant to scientific inquiry than Dennett's remarks may suggest.
