The readiness potential (RP) is one of the most controversial topics in neuroscience and philosophy due to its perceived relevance to the role of conscious willing in action. Libet and colleagues reported that RP onset precedes both volitional movement and conscious awareness of willing that movement, suggesting that the experience of conscious will may not cause volitional movement (Libet, Gleason, Wright, & Pearl, 1983). Rather, they suggested that the RP indexes unconscious processes that may actually cause both volitional movement and (...) the accompanying conscious feeling of will (Libet et al., 1983; pg. 640). Here, we demonstrate that volitional movement can occur without an accompanying feeling of will. We additionally show that the neural processes indexed by RPs are insufficient to cause the experience of conscious willing. Specifically, RPs still occur when subjects make self-timed, endogenously-initiated movements due to a post-hypnotic suggestion, without a conscious feeling of having willed those movements.

ABSTRACTThough the perennial problem of consciousness has outlasted the idealists, the reductivist turn in contemporary naturalistic philosophy of mind and the non-reductivist reactions to it provoke us to re-think post-Kantian idealism. Fichte's Wissenschaftslehre makes for a classical case of non-reductivist approach to mind and his critique of ‘dogmatism’ is all the more relevant in this context. This article contains four sections. The first section is an introduction that explains why post-Kantian idealism is relevant to contemporary philosophy of mind. The second (...) section pinpoints the placement issue that confronts not only current philosophers but also partially motivated Fichte's own philosophy. The third section is a short but essential remark about the normative and practical valence of ‘knowledge’ and ‘science’ in Fichte's traditional understanding of them. In the fourth section, I provide a reconstructive analysis of Fichte's understanding and critique of physicalism. Fichte's argument can be analyzed into two horns with each targeting reductivism and epiphenomenalism respectively. The final section is a brief but positive exposition on a necessary feature, namely reflexivity, of mind and the first-person perspective. Fichte's appropriation of intellectual intuition exemplifies a non-representationalist picture that connects content transparency with the active nature of mind. (shrink)

Change blindness provides a new technique for mapping visual attention with unprecedented spatial and temporal resolution. Change blindness can occur when a brief full‐field blank interferes with the detection of changes in a scene that occur during the blank. This interference can be overcome by attending to the location of a change. Because changes are detected at attended locations, but not at unattended locations, detection accuracy provides an indirect measure of the distribution of visual attention. The likelihood of detecting a (...) new element in a scene provides a measure of the occurrence of attention at that element's location. Potential new directions, advantages, and problems with this method are considered. (shrink)

What philosophical reasons are there that could ground Kant’s Declaration in 1799 against Fichte’s Doctrine of Science? To answer this question, the present paper reconstructs what Kant could have said but did not. The first section traces the possible peer influences on Kant’s stance toward Fichte expressed in the Declaration and derives from it what Kant conceived to be the problems with the Doctrine of Science. The second section establishes three formation conditions for transcendental paralogisms. The third section proposes a (...) Fichtean variant of paralogism and shows how in Fichte’s case the three formation conditions obtain. (shrink)

If perception is constructed, what keeps perception from becoming mere hallucination unlinked to world events? The visual system has evolved two strategies to anchor itself and correct its errors. One involves completing missing information on the basis of knowledge about what most likely exists in the scene. For example, the visual system fills in information only in cases where it might be responsible for the data loss. The other strategy involves exploiting the physical stability of the environment as a reference (...) frame with respect to which the eyes and body can move. (shrink)

Evaluation, as the expression of a writer’s attitudes, opinions and values, has become a key term in discourse studies in recent years and has proved to be a particularly fruitful way of analysing academic texts. But while studies have shown the importance of evaluation in research genres, its role in seemingly more promotional academic genres has been largely neglected. This article examines the journal description, a brief but ubiquitous feature of all journals, whether online or in print. Situated at the (...) academic—commercial interface, the JD provides information for prospective readers and authors while endorsing a particular view of the field and positioning the journal in the academic community. Drawing on a corpus of 200 JDs in four contrasting disciplines, we show how evaluation is a key feature of this genre, influencing both lexical choices and rhetorical structure. The analysis contributes both to our understanding of a neglected academic genre and the evaluative resources of language. (shrink)
