It is sometimes said that reasoning, thought and judgment essentially involve action. It is sometimes said that they involve spontaneity, where spontaneity is taken to be connected in some constitutive way with action—intentional, voluntary and indeed free action. There is, however, a fundamental respect in which reason, thought and judgment neither are nor can be a matter of action. Any spontaneity that reason, thought and judgment involve can be connected with freedom only when the word 'freedom' is used in the (...) Spinozan-Kantian sense according to which freedom is a matter of 'rational necessitation', determination by reason. (shrink)

The claim of the freedom of the will (understood as an individual who is transcendent to Nature) in the name of XXth century scientific knowledge, against the perspective of XVIIIth-XIXth century scientific materialism, is analysed and refuted in the present paper. The hypothesis of reductionism finds no obstacle within contemporary natural sciences. Determinism in classical physics is irrefutable, unless classical physics is itself refuted. From quantum mechanics, some authors argue that free will is possible because there is an ontological indeterminism (...) in the natural laws, and that the mind is responsible for the wave function collapse of matter, which leads to a choice among the different possibilities for the body. However, here I defend the opposite thesis because indeterminism does not imply free will, and because the considerations about an autonomous mind sending orders to the body is against neuroscience or evolutionary theories about human beings. The quantum theory of measurement can be interpreted without the intervention of human minds, but other fields of science cannot contemplate the mentalist scenario. A fatalistic or materialist view, which denies the possibility of a free will, makes much more sense in scientific terms. (shrink)

The shortest form of the Basic Argument against free will and moral responsibility runs as follows: [1] When you act, you do what you do—in the situation in which you find yourself—because of the way you are. [2] If you do what you do because of the way you are, then in order to be fully and ultimately responsible for what you do you must be fully and ultimately responsible for the way you are. But [3] You cannot be fully (...) and ultimately responsible for the way you are. So [4] You cannot be fully and ultimately responsible for what you do. This paper restates the Basic Argument and varies it in several different ways. (shrink)

In the visual system, the represented features of individual objects (shape, colour, movement, and so on) are distributed both in space and time within the brain. Representations of inner and outer event sequences arrive through different sense organs at different times, and are likewise distributed. Objects are nevertheless perceived as integrated wholes - and event sequences are experienced to form a coherent "consciousness stream." In their thoughtful article, Dennett & Kinsbourne ask how this is achieved.

The neurological experiments conducted by Benjamin Libet (1985) and Grey Walter (1993, in Dennett) provide evidence that our actions are caused by non-conscious brain events beyond our conscious awareness. Normally, we assume that our conscious choices lead us to do things. If these researchers have interpreted their evidence correctly, it may be that we lack free-will, for we could not control a non-conscious brain state. Libet however provides evidence that agents can “change their minds” just before performing some action. He (...) felt that this was the elbow-room for free-will. But it may be inconsistent for him to suggest this, since his evidence indicates that there is no room for conscious choice. In this paper we discuss these results and various objections to the interpretation of the work. South African Journal of Philosophy Vol. 26 (3) 2007: pp. 271-288. (shrink)

The first priority of this response is to address Libet's rebuttal of my reinterpretation of his data. Then, because many authors have commented on various aspects of the debate, the rest of the response is organized in terms of subject matter, not as replies to each individual commentator. First, I reply to an objection expressed by two separate commentators to part of my reinterpretation of those of Libet's data supposedly supporting backward referral. This leads to a brief discussion of the (...) whole concept of backward referral. The relevance of the flash-lag illusion to possible measurement errors in the Libet/Trevena and Miller paradigm is addressed next. Finally, I have a few words to say on the relationship between quantum mechanical ontology and free will. (shrink)
