subjects mean when they report their mental states it is useful to be guided by a sound grasp of their concepts for mental events. ³ Though this is often ignored in favor of libertarian notions of free will, in which free action is seen as completely undetermined by the subject.

Libet's experiments, supported by a strict one-to-one identity thesis between brain events and mental events, have prompted the conclusion that physical events precede the mental events to which they correspond. We examine this claim and conclude that it is suspect for several reasons. First, there is a dual assumption that an intention is the kind of thing that causes an action and that can be accurately introspected. Second, there is a real problem with the method of timing the mental events concerned given that Libet himself has found the reports of subjects to be unreliable in this regard. Third, there is a suspect assumption that there are such things as timable and locatable mental and brain events accompanying and causing human behaviour. For all these reasons we reject the claim that physical events are prior to and explain mental events.

Over the last 25 years, experimental findings published by Benjamin Libet have indicated that conscious acts of will are preceded by a characteristic kind of brain event of which the agent is not conscious. It, Libet says, rather than the will, is what causes actions. His discoveries, if correct, would seem to imply that the notion of a free, conscious will is an illusion, and that actions are initiated by neural processes not under conscious control. In what follows it is argued that Libet’s conclusion is incorrect, and that other evidence points to the essential causal role of consciousness in voluntary action.

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.

The paper provides new perspectives for a dualistic conception of mental causation by putting causation that originates in a nonphysical self into an evolutionary perspective. Nonphysical causation of this type - free agency -, together with nonphysical consciousness, is regarded as being not only compatible with physics, but also as having a natural place in nature. It is described how free agency can work, on the basis of the brain, and how it can be compatible with the result of the Libet-experiment. The necessary condition for the existence of free agency is that the physical macro-world is indeterministic to a degree that is relevant for living beings, that is, for their survival and well-being. From an evolutionary point of view, and on the basis of the facts of consciousness, it is more likely than not that this condition is in fact fulfilled.

Libet, Gleason, Wright, & Pearl (1983) asked participants to report the moment at which they freely decided to initiate a pre-specified movement, based on the position of a red marker on a clock. Using event-related potentials (ERPs), Libet found that the subjective feeling of deciding to perform a voluntary action came after the onset of the motor “readiness potential,” RP). This counterintuitive conclusion poses a challenge for the philosophical notion of free will. Faced with these findings, Libet (1985) proposed that conscious volitional control might operate as a selector and a controller of volitional processes rather than as an initiator of them.

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 act? Are the physiological facts compatible with the belief that free will determines our voluntary acts? What is the role of consciousness in voluntary action? In this paper I will discuss these questions and the answers that Libet gave to them.
