Cognition is embodied when it is deeply dependent upon features of the physical body of an agent, that is, when aspects of the agent's body beyond the brain play a significant causal or physically constitutive role in cognitive processing. In general, dominant views in the philosophy of mind and cognitive science have considered the body as peripheral to understanding the nature of mind and cognition. Proponents of embodied cognitive science view this as a serious mistake. Sometimes the nature of the dependence of cognition on the body is quite unexpected, and suggests new ways of conceptualizing and exploring the mechanics of cognitive processing. Embodied cognitive science encompasses a loose-knit family of research programs in the cognitive sciences that often share a commitment to critiquing and even replacing traditional approaches to cognition and cognitive processing. Empirical research on embodied cognition has exploded in the past 10 years. As the bibliography for this article attests, the various bodies of work that will be discussed represent a serious alternative to the investigation of cognitive phenomena. Relatively recent work on the embodiment of cognition provides much food for thought for empirically-informed philosophers of mind. This is in part because of the rich range of phenomena that embodied cognitive science has studied. But it is also in part because those phenomena are often thought to challenge dominant views of the mind, such as the computational and representational theories of mind, at the heart of traditional cognitive science. And they have sometimes been taken to undermine standard positions in the philosophy of mind, such as the idea that the mind is identical to, or even realized in, the brain.

  This paper examines the standard view of realization operative incontemporary philosophy of mind, and proposes an alternative, generalperspective on realization. The standard view can be expressed, insummary form, as the conjunction of two theses, the sufficiency thesis andthe constitutivity thesis. Physicalists of both reductionist and anti-reductionist persuasions share a conception of realization wherebyrealizations are determinative of the properties they realize and physically constitutive of the individuals with those properties. Centralto the alternative view that I explore here is the idea that the requisite,metaphysically robust notion of realization is ineliminably context-sensitive. I shall argue that the sufficiency and constitutivity theses aretypically not jointly satisfied by any one candidate realizer, and that goingcontext-sensitive in one's metaphysics is preferable to the standard view.The context-sensitive views developed here are implicit in a range ofcommon views in both the philosophy of mind and the philosophy of biology,even if they have not been explicitly articulated, and even though theyundermine other views that are commonly endorsed

The relationship of eugenics to science is intricate and many-layered, starting with Sir Francis Galton’s original definition of eugenics as “the science of improving stock”. Eugenics was originally conceived of not only as a science by many of its proponents, but as a new, meliorative science emerging from findings of a range of nascent sciences, including anthropology and criminology in the late 19th-century, and genetics and psychiatry in the early 20th-century. Although during the years between the two World Wars many central claims made by eugenicists were critiqued by scientists in these disciplines, in more recent years forms of eugenics (e.g., liberal eugenics”) have been defended as an inevitable outcome of biotechnologies and respect for autonomous choice. Understanding the shifting and varied roles that science has played in eugenics requires an appreciation of the ways in which science and values are intertwined.

This is a book that challenges the current orthodoxy, both in the philosophy of mind and in the cognitive sciences, that thinking (construed broadly to include perceiving, imagining, remembering, etc.) is a mental process in the head. Such a view has been largely taken for granted since the demise of behaviorism in the 1960s, and it underpins both the representational and computational theories of mind, including their connectionist and dynamicist variants. While the orthodoxy has been rejected in recent years by a motley collection of e-theorists—externalists, embodiers, embedders, and extended minders—Melser’s view is quite distinct from such views. For Melser, rather than thinking being a process that begins in the head but extends beyond it (as most e-theorists hold), it is a personal-level activity, something that a person does through her actions. Since Melser views such activities as being disjoint from natural processes, thinking is not a natural process at all, the sort of thing that we might study scientifically. Thus, thinking is a personal action that calls for a different kind of study, one that draws on empathy, interpretation, and hermeneutics. That is the view defended at the core of the book (chh.1-7), and if it makes it sound like a very old-fashioned book, that’s because it is. Melser’s antecedents are philosophers such as Gilbert Ryle, J.L. Austin, and Stuart Hampshire, both in style and in content. Apart from Melser’s heavy reliance on selective parts of developmental psychology, there is minimal discussion of substantive work in contemporary cognitive science. That is what might be expected from an author whose view is that whatever it is cognitive scientists are doing, it is not (much to their surprise, no doubt) the investigation of thinking. As I will try to show in a moment, however, the central argument of the book could have been strengthened by more direct engagement with such empirical work.

In the intersection between eugenics past and present, disability has never been far beneath the surface. Perceived and ascribed disabilities of body and mind were one of the core sets of eugenics traits that provided the basis for institutionalized and sterilization on eugenic grounds for the first 75 years of the 20th-century. Since that time, the eugenic preoccupation with the character of future generations has seeped into what have become everyday practices in the realm of reproductive choice. As Marsha Saxton (2000) and Adrienne Asch (2000, 2003) have forcefully argued, the use of prenatal screening technologies to facilitate the selective abortion of fetuses with features that signify disabling traits—the paradigm here being trisomy 21 in a fetus indicating Down Syndrome in the child—express a negative view of such disabilities sufficient to warrant terminating an otherwise wanted pregnancy. The eliminative structure of what Rosemary Garland Thompson (2012) has called eugenic logic persists in contemporary practices governing reproductive choice, social inclusion, and democratic participation and their relationship to disability. The tie between eugenics and contemporary disability studies suggests that eugenics and reflection on its history can also play a more positive role in disability politics. After focusing on eugenics in the first half of the paper, we will shift in the second half of the paper to eugenic resonances in contemporary thought and practice, concluding with some thoughts about ongoing practices of silencing and the very idea of eradicating disability.

This paper considers ten questions that those puzzled by or skeptical of extended cognition have posed. Discussion of these questions ranges across substantive, methodological, and dialectical issues in the ongoing debate over extended cognition, such as whether the issue between proponents and opponents of extended cognition is merely semantic or a matter of convention; whether extended cognition should be treated in the same way as extended biology; and whether conscious mental states pose a special problem for the extended mind thesis. Lethocerus, the giant water bug, will be a recurrent reference point for much of the discussion
