Researchers in the psychological sciences have put forward the thesis that various sources of psychological, cognitive, and neuroscientific evidence demonstrate that being conscious of our mental states does not make any difference to our behaviour. In this paper, I argue that the evidence marshalled in support of this view — which I call psychological epiphenomenalism — is subject to major objections, relies on a superficial reading of the relevant literature, and fails to engage with the more precise ways in which (...) philosophers understand mental states to be conscious. I then appeal to work on implementation intentions to demonstrate that an intention's being 'access conscious' enhances its functional role, which makes it more likely that we will successfully carry out our intended behaviour. The result is that consciousness in at least one relevant sense is not epiphenomenal, with further work remaining to be done to show how other kinds of consciousness cause behaviour too. (shrink)

Striking experimental results by Benjamin Libet and colleagues have had an impor- tant impact on much recent discussion of consciousness. Some investigators have sought to replicate or extend Libet’s results (Haggard, 1999; Haggard & Eimer, 1999; Haggard, Newman, & Magno, 1999; Trevena & Miller, 2002), while others have focused on how to interpret those findings (e.g., Gomes, 1998, 1999, 2002; Pockett, 2002), which many have seen as conflicting with our commonsense picture of mental functioning.

This article addresses two influential lines of argument for what might be termed “scientific epiphenomenalism” about conscious intentions – the thesis that neither conscious intentions nor their physical correlates are among the causes of bodily motions – and links this thesis to skepticism about free will and moral responsibility. One line of argument is based on Benjamin Libet’s neuroscientific work on free will. The other is based on a mixed bag of findings presented by social psychologist Daniel Wegner. It is (...) argued that both lines of argument are unsuccessful. (shrink)

This book aims to show that recent developments in neuroscience permit a defense of free will. Through language, human beings can escape strict biological determinism.

Although philosophers have explored several connections between neuroscience and moral responsibility, the issue of how real-world neurological modifications, such as Deep Brain Stimulation, impact moral responsibility has received little attention. In this article, we draw on debates about the relevance of history and manipulation to moral responsibility to argue that certain kinds of neurological modification can diminish the responsibility of the agents so modified. We argue for a historicist position - a version of the history-sensitive reflection view - and defend (...) that account against a rival, relational view of responsibility. We conclude that DBS can, under certain conditions, diminish responsibility, and explore the circumstances under which this might be so. We conclude by suggesting that philosophical debates about moral responsibility, manipulation, and history have greater practical relevance than is sometimes thought, and that attention to practical cases can help inform and deepen this body of scholarship.

This article describes three experiments that would advance our understanding of the import of data already generated by scientific work on free will and related issues. All three can be conducted with existing technology. The first concerns how reliable a predictor of behavior a certain segment of type I and type II RPs is. The second focuses on the timing of conscious experiences in Libet-style studies. The third concerns the effectiveness of conscious implementation intentions. The discussion of first two experiments (...) highlights some important problems with certain inferences made on the basis of existing data in scientific work on free will. The discussion of the third calls attention to powerful evidence that conscious intentions sometimes are among the causes of corresponding actions. This evidence has been largely ignored in the literature on free will. (shrink)

Pope John Paul II called for an intense dialogue between science and theology, “a common interactive relationship,” in which each discipline is “open to the discoveries and insights of the other” while retaining its own integrity. This essay seeks to be responsive to that call and is an initial exploration of relationships between contemporary neuroscience and Catholic theological ethics. It examines neuroscientific data on the bicameral brain and theological ethical data on marital ethics, including divorce and remarriage, and asks what (...) insight the former might provide into both the latter and the different ethical methods that respond to marital ethics. The analysis is undertaken in the hope of illuminating a pathway that opens the insights of one way of doing theological ethics to the insights of another way, thereby eliminating the unnecessary, unhelpful, and sometimes un‐Christian polarizations that presently separate them.
