Many traditional attempts to show that nonhuman animals are deserving of moral consideration have taken the form of an argument by analogy. However, arguments of this kind have had notable weaknesses and, in particular, have not been able to convince two kinds of skeptics. One of the most important weaknesses of these arguments is that they fail to provide theoretical justifications for why particular physiological similarities should be considered relevant. This paper examines recent empirical research on pain and, in particular, (...) explores the implications of the dissociation between the sensory and the affective pain pathways. It is argued that these results show that the belief that nonhuman animals experience pain in a morally relevant way is reasonable, though not certain. It is further argued that the proposal to explore the relationship between consciousness and various forms of learning challenges the aforementioned skeptics to provide more physiological details for their claims that nonhuman mammals are probably not conscious.

The aim of this article is (1) to investigate the ‘neurosciences’ as an object of study for historical and genealogical approaches and (2) to characterize what we identify as a particular ‘style of thought’ that consolidated with the birth of this new thought community and that we term the ‘neuromolecular gaze’. This article argues that while there is a long history of research on the brain, the neurosciences formed in the 1960s, in a socio-historical context characterized by political change, faith (...) in scientific and technological progress, and the rise of a molecular gaze in the life sciences. They flourished in part because these epistemological and technological developments were accompanied by multiple projects of institution-building. An array of stakeholders was mobilized around the belief that breakthroughs in understanding the brain were not only crucial, they were possible by means of collaborative efforts, cross-disciplinary approaches and the use of a predominantly reductionist neuromolecular method. The first part of the article considers some of the different approaches that have been adopted to writing the history of the brain sciences. After a brief outline of our own approach, the second part of the article uses this in a preliminary exploration of the birth of the neurosciences in three contexts. We conclude by arguing that the 1960s constitute an important ‘break’ in the long path of the history of the brain sciences that needs further analysis. We believe this epistemological shift we term the ‘neuromolecular gaze’ will shape the future intellectual development and social role of the neurosciences. (shrink)

In this essay we provide (1) an argument for why ethics should be naturalized, (2) an analysis of why it is not yet naturalized, (3) a defense of ethical naturalism against two fallacies—Hume’s and Moore’s—that ethical naturalism allegedly commits, and (4) a proposal that normative ethics is best conceived as part of human ecology committed to pluralistic relativism. We explain why naturalizing ethics both entails relativism and also constrains it, and why nihilism about value is not an especially worrisome for (...) ethical naturalists. The substantive view we put forth constitutes the essence of Duke Naturalism. (shrink)

The prefrontal cortex has long been suspected to play an important role in cognitive control, in the ability to orchestrate thought and action in accordance with internal goals. Its neural basis, however, has remained a mystery. Here, we propose that cognitive control stems from the active maintenance of patterns of activity in the prefrontal cortex that represent goals and the means to achieve them. They provide bias signals to other brain structures whose net effect is to guide the flow of (...) activity along neural pathways that establish the proper mappings between inputs, internal states, and outputs needed to perform a given task. We review neurophysiological, neurobiological, neuroimaging, and computational studies that support this theory and discuss its implications as well as further issues to be addressed. (shrink)
