This introduction to a special issue of Topoi introduces and summarises the relationship between three main varieties of 'enactivist' theorising about the mind: 'autopoietic', 'sensorimotor', and 'radical' enactivism. It includes a brief discussion of the philosophical and cognitive scientific precursors to enactivist theories, and the relationship of enactivism to other trends in embodied cognitive science and philosophy of mind.

This chapter focuses on synaesthesia research in the 21st century. It begins by giving counts of publications and these are further broken down by type, focus, and measures used. Then, there is a review of major questions being addressed by current research in the area of synaesthesia. The amount of research being done in this area is growing rapidly, and is incorporating a number of different research approaches to address a wide variety of questions.

This article describes aspects of our biological nature that have contributed to the dangerous current state of societal, ecological and climatological affairs. Next, it deals with stratagems to take these aspects into account, so as to allow us better choices. I will concentrate on the concepts of evolved group mechanisms and “neoteny” and explain why they direct our responses throughout our lives. The connection between our biological make‐up and our vulnerability to the current rise of certain kinds of irrational, undemocratic, (...) populism is also laid bare. I will end by listing some simple, but possibly controversial, proposals that might have value in combating these societal tendencies and help decision making in a reality‐based, more scientific, manner.

The philosophical literature would have us believe that the conservative view on abortion is based on the claim that the fetus is a person from the time of conception. Given the widespread acceptance of this analysis, it comes as something of a surprise to learn that it conflicts with a number of major arguments offered in support of the conservative view. I argue, in the present paper, that a careful examination of these inconsistencies establishes that the personhood analysis is mistaken: (...) the conservative view is based on the natural process of fetal development, not the personhood of the fetus.

In lieu of an abstract, here is a brief excerpt of the content:Rhetoric and Power: An Inquiry into Foucault’s Critique of ConfessionDave TellOn October 10, 1979, Michel Foucault revised his thesis on confession. On that day, some three years after the publication of his magisterial treatment of confession in the first volume of The History of Sexuality, Foucault argued that the Pythagoreans, Stoics, and Epicureans had, before the advent of Christianity, their own practices of confession. Yet these practices, unlike their (...) Christian variants, were not complicit with practices of domination (OS 310, 312). In the context of Foucault’s thought theretofore, in which the confession consistently figured as an essential component in the exercise of modern power, this is a radical shift. In lectures given at both Berkeley and Dartmouth in the fall of 1980, Foucault made similar arguments. On these occasions he argued that Seneca’s De ira constituted a “stoic confession,” the object of which was to enable the subject to “live differently, better, more happily, than other people” (AB 210, 205). Judith Butler captures the gravity of the shift: “In the last years of his life, Foucault returned to the question of confession, reversing his earlier critique in the first volume of the History of Sexuality, where he indicts confession as a forcible extraction of sexual truth, a practice in the service of a regulatory power” (2005, 112).This reversal was short lived. Although Foucault would celebrate ancient Greek techniques of the self for the rest of his life, he would not [End Page 95] long refer to these techniques in terms of confession. Thus, in another reading of De ira, this one in March 1982, Foucault again noted that the Stoics have “confessional practices” that are “very close to what is found in Christianity” (Herm 482). This time, however, he insisted that the Stoic practices were fundamentally different: “However, all these elements seem to me to be profoundly different from what we should call ‘confession’ in the strict, or anyway, spiritual sense of the word” (Herm 365). In The Care of the Self, Foucault again conceded that De ira—what he now called “the most detailed description” of antique practices of the self—looked “at first glance” like a Christian confession, but he again maintained that it is something quite different: “The purpose of the examination is not therefore to discover one’s own guilt, down to its most trifling forms” (CS 61–62). Foucault concluded that the various “discourses of the self”—the confession and the Greek techniques of the self—could not be placed into a single category (see GE 250). Indeed, the “profound difference” (Herm 299) between these two discourses of the self was perhaps Foucault’s most repeated claim of the 1980s (see Herm 222, 237–44, 299, 308; GE 247–48; WS 237; AB 207–8; RFT 27; UP 89; CS 239; SS 5; FI 5, 12; FS 30, 35, 44, 87, 96, 97, 143–45, 147).It is worth asking why Foucault returned so consistently to the distinction between these two discursive forms. This question gains even more relevance for readers of this journal when we remember that, on at least two occasions, Foucault defined one of these forms, the ancient techniques of the self, in terms of its opposition to rhetoric: the techniques of the self, he claimed, are “nonrhetorical” (Herm 368; FS 20). Thus the question that drives this essay is not so much why Foucault attached such importance to the distinction but rather how rhetoric itself might differentiate the confession from the techniques of the self. Stated differently, Foucault’s work on the confession vis-à-vis the technologies of the self provides a valuable opportunity to study the role of rhetoric in Foucault’s thought—not because they are both rhetorical forms but, curiously, because Foucault insists that one is not.In order to foreground the work of rhetoric in Foucault’s thought, I situate his discourses of the self in the context of Nietzsche’s critique of metonymy. Although this may seem arbitrary, it gains initial plausibility from three facts. First, we know that Foucault understood rhetoric in terms of tropes (OT 84; Cooper 1988, 4). Second, we know too that Foucault had a deep... (shrink)

Based on our respective research programs (psychiatry, forensic psychiatry, public health, HIV/AIDS, harm reduction) this article aims to use purposely non‐conventional means to present the substantial contribution of poststructuralist perspectives to knowledge development in nursing science in general and in our current research in particular. More specifically, we call on the work of Michel Foucault and Deleuze & Guattari to politicize nursing science using examples from our empirical research programs with marginal and often highly marginalized populations. We discuss the concepts (...) of power, discourse, and resistance to illustrate the essential contribution of poststructuralism to marginal, even “nomadic”, nursing research. (shrink)

Social and linguistic perceptions are linked. On one hand, talker identity affects speech perception. On the other hand, speech itself provides information about a talker's identity. Here, we propose that the same probabilistic knowledge might underlie both socially conditioned linguistic inferences and linguistically conditioned social inferences. Our computational–level approach—the ideal adapter—starts from the idea that listeners use probabilistic knowledge of covariation between social, linguistic, and acoustic cues in order to infer the most likely explanation of the speech signals they hear. (...) As a first step toward understanding social inferences in this framework, we use a simple ideal observer model to show that it would be possible to infer aspects of a talker's identity using cue distributions based on actual speech production data. This suggests the possibility of a single formal framework for social and linguistic inferences and the interactions between them. (shrink)

Neurotheology is a fast-growing field of research. Combining philosophy of mind, neuroscience, and religious studies, it takes a new approach to old questions on religion. What is religion and why do we have it? Neurotheologists focus on the search for the neural correlate of religious experiences. If we can trace religious experiences to specific parts of the brain, chances are we can reduce religion as such to that grey soggy matter as well. This article predicts neurotheology will not be able (...) to locate the neural correlate of religious experiences. As we cannot decide phenomenally what makes an experience religious, neurologically we cannot find its correlate either. That is, if there are fixed neural correlates to begin with, because their existence is still a matter of debate. In addition, religious experiences seem to be a kind of experience, like emotional or relational experiences, making them indistinguishable from similar nonreligious experiences. Even if one manages to trace the neural correlate of religious experiences, neurotheology will still not be able to account for the rise of religion without resorting to theories from other disciplines. In the end, we do not know enough about consciousness and the way it relates to the brain to make conclusive claims about the search for religious states of consciousness. It seems, however, that even though neurotheology could provide fascinating insights in the workings of the religious brain, on its own, it will prove unable to explain religion fully. (shrink)

Recently, a review regarding the mechanics and evolution of mitochondrial fission appeared in Nature. Surprisingly, it stated authoritatively that the mitochondrial outer membrane, in contrast with the inner membrane of bacterial descent, was acquired from the host, presumably during uptake. However, it has been known for quite some time that this membrane was also derived from the Gram‐negative, alpha‐proteobacterium related precursor of present‐day mitochondria. The zombie idea of the host membrane still surrounding the endosymbiont is not only wrong, but more (...) importantly, might hamper the proper conception of possible scenarios of eukaryogenesis. Why? Because it steers the imagination not only with regard to possible uptake mechanisms, but also regarding what went on before. Here I critically discuss both the evidence for the continuity of the bacterial outer membrane, the reasons for the persistence of the erroneous host membrane hypothesis and the wider implications of these misconceptions for the ideas regarding events occurring during the first steps towards the evolution of the eukaryotes and later major eukaryotic differentiations. I will also highlight some of the latest insights regarding different instances of endosymbiont evolution. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:When Should “Riskier” Subjects Be Excluded from Research Participation?*Dave Wendler** (bio)AbstractThe exclusion of potential subjects based on increased risks is a common practice in human subjects research. However, there are no guidelines to ensure that this practice is conducted in a systematic and fair way. This gap in the literature and regulations is addressed by a specific account of a “condition on inclusion risks” (CIR), a condition under (...) which potential subjects should be excluded from research on the basis of increased risks. This account provides a general framework for assessing standard exclusions as well as more controversial ones such as the exclusion of pregnant women and women of childbearing potential from certain types of research.The exclusion of potential subjects on the basis of increased risks is a common and, in most instances, noncontroversial practice in human subjects research. Investigators routinely exclude potential subjects with reduced kidney function, bleeding disorders, and allergies to the drugs under investigation. Surprisingly, this use of exclusion criteria takes place in the absence of any explicit guidelines. In the present paper, I attempt to fill this gap in the literature and regulations by offering a specific account of the conditions under which potential subjects should be excluded from research on the basis of increased risk. This account serves two purposes.First, subjects who are excluded on the basis of increased risk are prevented from making their own enrollment decisions. Therefore, it is important to ensure, in spite of the broad range of potential subjects and the varied reasons for excluding them, that potential subjects are excluded in [End Page 307] a systematic and fair way. Second, certain instances of subject exclusion, most notably the exclusion of pregnant women and women of childbearing potential, raise more difficult issues. By providing a general framework for assessing the exclusion of potential subjects based on increased risks, the present analysis covers these cases as well and, thus, offers a solution to one of the thornier ethical dilemmas facing investigators and IRBs today.Briefly, I argue that standard exclusion practices suggest that whenever two groups of potential research subjects offer the same opportunity for scientific and individual benefit, but different levels of risk, the group that would introduce greater risks should be excluded. With this framework in place, I consider potential subjects, such as men and women of child-parenting potential, whose research participation introduces increased risks to third parties. I argue that the present approach is justified, not because it reduces harms to specific individuals, but because it reduces aggregate harms. Therefore, it should be applied to all riskier potential subjects regardless of who faces the risks in question. After defending this approach, I consider several objections.First, I argue that the present approach is not paternalistic; the exclusions it calls for are not justified by what is thought to be in the best interests of the individuals excluded. Rather, the argument is that these exclusions minimize the aggregate harm of human subjects research. In addition, the present approach does not violate the obligation of researchers to respect subject autonomy because it does not reduce the number of potential subjects who are given the opportunity to enroll in a particular protocol. Finally, the exclusions are consistent with reasonable side constraints on attaining the goals of research.“Riskier” SubjectsWhen it comes to evaluating risks, most guidelines on human subjects research stipulate simply that the risks entailed must be reasonable given the potential for benefit. The Australian National Health and Medical Research Council’s guidelines, for instance, require only that “the investigator... must be satisfied that the possible advantage to be gained from the work justifies any discomfort or risk involved” (ANMRC 1992, Clause 3). To determine whether the risks of a protocol are justified, one sums the risks of the various procedures in the protocol, whatever those procedures may be, and compares the result to the procedures’ potential for benefit. This evaluation of risks assumes that the aggregate risks of a [End Page 308] given protocol are fixed and thus will not help to determine whether and when the risks of particular protocols should be reduced by excluding riskier subjects. The United States Department of Health... (shrink)

We present a specific elaboration and partial defense of the claims that cognition is enactive, embodied, embedded, affective and (potentially) extended. According to the view we will defend, the enactivist claim that perception and cognition essentially depend upon the cognizer’s interactions with their environment is fundamental. If a particular instance of this kind of dependence obtains, we will argue, then it follows that cognition is essentially embodied and embedded, that the underpinnings of cognition are inextricable from those of affect, that (...) the phenomenon of cognition itself is essentially bound up with affect, and that the possibility of cognitive extension depends upon the instantiation of a specific mode of skillful interrelation between cognizer and environment. Thus, if cognition is enactive then it is also embodied, embedded, affective and potentially extended. (shrink)

Traditional health sciences (including nursing) paradigms, conceptual models, and theories have relied heavily upon notions of the ‘person’ or ‘patient’ that are deeply rooted in humanistic principles. Our intention here, as a collective academic assemblage, is to question taken‐for‐granted definitions and assumptions of the ‘person’ from a critical posthumanist perspective. To do so, the cinematic works of filmmaker David Cronenberg offer a radical perspective to revisit our understanding of the ‘person’ in nursing and beyond. Cronenberg's work explores bodily transformation and (...) mutation, with the body as a fragile and malleable vessel. Cronenberg's work allows us to interrogate the body in all its complexity, contingency, and hybridity and provides avenues of rupture within current understandings of ‘the person’. Reinventing the definition of what it means to be human, critical posthumanism offers opportunities to both critique humanist theories and build affirmative futurities. Also drawing on the work of Deleuze and Guattari, specifically, their concept of becoming, we propose a critical posthumanist alternative to the conceptualization of the person in the health sciences, that of the becoming‐mutant, so frequently explored in Cronenberg's films. Such a conceptualization permits the inclusion of various technological interventions of the contemporary subject: The postperson. This position offers the health science disciplines a radical reconceptualization of the conceptual and theoretical approaches, extending beyond those trapped within the quagmire of humanistic principles.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Nature of Space by Milton SantosDave McLaughlinThe Nature of Spaceby milton santos (trans. by brenda baletti) Durham, N.C.: Duke University Press, 2021When asked to review Milton Santos’s The Nature of Space, I was interested mostly in the book’s core theme. As a literary geographer, my own research focuses heavily on space as an analytical concept and a lived experience; I was keen to read and understand a (...) fresh perspective on this topic. Little did I know that opening this book would connect me to a world of geography scholarship for the most part ignored, actively or otherwise, in the Anglophone academy. For my sins, I was not alone in this ignorance. In 2017, for example, one scholar felt confident in writing that:The English-speaking geographical community knows very little about the theoretical work in geography being produced in the so-called [End Page 147] “global South.” They are unaware, for example, of the work of Brazilian geographer Milton Santos.1It is not my place here to write about the reasons why this is such a mistake. Others, better qualified than me, have already done so.2 My aim here is to do three things. First, to put Santos’s arrival into English-language geography in context; second, to consider briefly his key contribution to defining the nature of space; and finally, to touch on what Santos’s book offers us more broadly.Published in 2021, Brenda Baletti’s translation of Santos’s great work arrived on the crest of a wave of discussions, debates, and scholarly interventions around decoloniality in Western geography. This movement emphasizes uncovering “still colonising frames of knowledge”3—frames “through which the world is apprehended and explained and modelled for the future”—and “craft[ing] ways of thinking harder about and against them.”4 Others have argued that the long wait for an English translation of Santos’s The Nature of Space is evidence of just such modes of thought continuing, unreflectively, among Anglophone academia. In 2019, an English-language translation of Santos’s For a New Geography was published by the University of Minnesota Press, followed by The Nature of Space in 2021. Hopefully, publications indicate that some publishers, at least, are following Stephen Legg’s call to think hard against certain predominant Western frames.The Nature of Space, despite its mere 280 pages, is an opus of sorts. Santos’s style eschews narrow conceptualization in favor of building a solid theory of space on a remarkably broad foundation of thinkers, including Braudel, Merleau-Ponty, Habermas, Latour, and many, many others. This broad foundation is a result not only of his long career and his own widely travelled life; it is necessary due to the slippery and almost-undefinable nature of space itself. In a wonderful section of For a New Geography, Santos lays out the problem facing geographers in defining this concept around which our discipline revolves:I understand why geographers have spent more time defining geography than space as the latter is extremely hard to do. The same could be said of space as Saint Augustine said of time: “if I ask myself if I know [End Page 148] what it is, I respond that I do; but, if I ask myself to define it, I respond that I do not know how.”5Part of this complication, recognized by Santos, is that “space” is a word with many meanings outside academia.6 Yet, geographers also face no simple task in defining this core concept for our own needs. Doreen Massey’s definition from For Space is one of my favorites, not only because it well illustrates the complexity of the term “space,” but also due to the range of reactions it produces in my first-year undergraduate students when I introduce it: Space is the sphere of the possibility of the existence of multiplicity in the sense of contemporaneous plurality.7 This is a very crunchy sentence! But it gets to the heart of a conceptually complex truth: that space is the dimension in which things happen, a dimension in which we must live at all times, as well as... (shrink)

Humanity is in a tight race between planetary catastrophe and enlightenment. It’s not clear which will prevail. The old paradigm, that of materialism, individualism, and fierce competition, is failing at all levels—economic, social, political, and environmental—and bringing life as we know it to the edge of a precipice. At the same time, a “new” paradigm is emerging, one that emphasizes interconnectedness, the sacredness of all creation, universal consciousness, and cooperation. In truth, the “new” paradigm is anything but new. What’s new (...) is that scientific discoveries are now beginning to resonate with and reinforce ancient wisdom, wisdom that has been imbedded in indigenous mythologies for millennia. It’s incumbent upon those who have already transitioned to a more sustainable “myth of meaning” to find ways to encourage others along the path. A demographic naturally resonant to holistic worldviews, but largely untapped, is that of undergraduate Honors students. This paper describes a pioneering Honors course at James Madison University that, by many measures, has succeeded in integrating science and spirituality into a new way of thinking and being.

In recent years, positive psychology and mindfulness practices have increasingly been integrated in neo-liberal organisations to promote individuals’ well-being. Critics have argued that these practices actually function as management techniques, encouraging individuals’ self-governance and acceptance of the status quo despite adverse contexts. This article extends this argument by unpacking ways in which such ‘well-being’ programmes are also gendered, having been formulated around neo-liberal hegemonic masculine values of rationality, individualism and competition, and further masculinised through integration into gendered organisations. The argument (...) is presented that this process produces a neo-liberal version of hegemonic masculinity that the author calls ‘mindful masculinity’. This theoretical argument is illustrated through examples of specific ways in which ‘well-being’ practices have been reworked in strongly masculine settings to promote neo-liberal hegemonic masculine goals under a symbolic veneer of spirituality and mental health.

Skepticism about the limits of online learning is as old as online learning itself. As with other technologically-driven innovations in pedagogy, there are deep-seated worries that important educational goods might be effaced or obscured by the ways of teaching and learning that online methods allow. One family of such worries is inspired by reflections on the bodily basis of an important kind of understanding, and skepticism over whether this bodily basis can be inculcated in the absence of actual, flesh-and-blood, classroom (...) interactions. This paper focuses on the ways in which such worries arise in the influential work of Hubert Dreyfus. The negative conclusion for which I argue is that endorsing Dreyfus's Merleau-Pontian picture of the relationship between bodily skill and understanding does not commit us to his general pessimism concerning online learning—bodily, emotional, and interactive dimensions might be essential to learning, but we lack reasons to think that online learning necessarily lacks these dimensions. The negative argument motivates a positive claim: rather than giving up on online learning we should focus on designing courses and pedagogies that scaffold the bodily, affective and interactive dynamics constitutive of understanding in a particular domain.

The aim of this article is to bring to the attention of the international nursing community the discrepancy between a pervasive ‘caring’ nursing discourse and a most unethical nursing practice in the United States. In this article, we present a duality: the conflict in American prisons between nursing ethics and the killing machinery. The US penal system is a setting in which trained healthcare personnel practice the extermination of life. We look upon the sanitization ofdeathworkas an application of healthcare professionals’ (...) skills and knowledge and their appropriation by the state to serve its ends. A review of the states’ death penalty statutes shows that healthcare workers are involved in the capital punishment process and shielded by American laws (and to a certain extent by professional boards through their inaction). We also argue that the law's language often masks that involvement; and explain how states further that duplicity behind legal formalisms. In considering the important role healthcare providers, namely nurses and physicians, play in administering death to the condemned, we assert that nurses and physicians are part of the states’ penal machinery in America. Nurses and physicians (as carriers of scientific knowledge, and also as agents of care) are intrinsic to the American killing enterprise. Healthcare professionals who take part in execution protocols are state functionaries who approach the condemned body as angels of death: they constitute an extension of the state which exercises its sovereign power over captive prisoners.

An expanded edition of Hickey's controversial and exquisitely written apologia for beauty--championed by artists, reviled by art critics, and as powerful as ever 30 years on 1993: the AIDS pandemic rages through yet another decade, leaving society and the arts devastated and bereft. Dave Hickey sits down to produce a slim volume, The Invisible Dragon. The book ignites a firestorm, and from its ashes "beauty" again rises as a dominant force in artistic life. Academics argue about theoretical minutiae. Artists (...) pass the book around like a samizdat. This 30th-anniversary edition brings back into print Dragon's four essays on beauty and commingles them with five previously uncollected essays. Hickey's 1974 profile of Dolly Parton anticipates Dolly's longevity as a cultural and feminist icon; his appreciation of Richard Pryor weaves an elegiac tapestry; his review of John Rechy's seminal gay novel Numbers outs its literary innovation in the face of a homophobia that otherwise ghettoized it; and his singular essay on Ed Ruscha, a paragon of arts writing by an extraordinary prose stylist, enjoins us to listen to art, not just look at it. An afterword by Hickey's friend and Dragon's editor "queers" the brash, heterosexual gambler as it situates the creation of Dragon squarely within the AIDS pandemic. The book was in part an attempt to make beauty visible under the looming presence of death and bodily decay. Only now can we fully appreciate how artists continue to harness beauty as a source of meaning and joy. Dave Hickey (1938-2021) was one of the preeminent arts and cultural writers of the turn of the 21st century. A MacArthur "Genius" Fellow known as the "beauty guy" in the popular press, Hickey opened A Clean, Well-Lighted Place gallery in Austin, Texas, in the 1960s, before becoming executive editor at Art in America magazine. In the 1970s, he was a songwriter in Nashville, Tennessee, where he coined and helped create the "Outlaw country" music movement. By the 1990s, Hickey had made a home in Las Vegas, from where he regularly traveled to speak with audiences worldwide. (shrink)

Aspects of peroxisome evolution, uncoupling, carnitine shuttles, supercomplex formation, and missing neuronal fatty acid oxidation (FAO) are linked to reactive oxygen species (ROS) formation in respiratory chains. Oxidation of substrates with high FADH2/NADH (F/N) ratios (e.g., FAs) initiate ROS formation in Complex I due to insufficient availability of its electron acceptor (Q) and reverse electron transport from QH2, e.g., during FAO or glycerol‐3‐phosphate shuttle use. Here it is proposed that the Q‐cycle of Complex III contributes to enhanced ROS formation going (...) from low F/N ratio substrates (glucose) to high F/N substrates. This contribution is twofold: 1) Complex III uses Q as substrate, thus also competing with Complex I; 2) Complex III itself will produce more ROS under these conditions. I link this scenario to the universally observed Complex III dimerization. The Q‐cycle of Complex III thus again illustrates the tension between efficient ATP generation and endogenous ROS formation. This model can explain recent findings concerning succinate and ROS‐induced uncoupling. (shrink)

Explains, in graphic novel format, the thinking of the most important philosophers in the Western tradition, including Aristotle, Francis Bacon, and Jean-Paul Sartre.

Synaesthetes persistently perceive certain stimuli as systematically accompanied by illusory colours, even though they know those colours to be illusory. This appears to contrast with cases where a subject’s colour vision adapts to systematic distortions caused by wearing coloured goggles. Given that each case involves longstanding systematic distortion of colour perception that the subjects recognize as such, how can a theory of colour perception explain the fact that perceptual adaptation occurs in one case but not the other? I argue that (...) these cases and the relationship between them can be made sense of in light of an existing view of colour perception. Understanding colours as ways in which objects and surfaces modify light, perceived through grasping patterns and variations in colour appearances, provides a framework from which the cases and their apparent disanalogy can be predicted and explained. This theory’s ability to accommodate these cases constitutes further empirical evidence in its favour. (shrink)

What kind of symbiosis between archaeon and bacterium gave rise to their eventual merger at the origin of the eukaryotes? I hypothesize that conditions favouring bacterial uptake were based on exchange of intermediate carbohydrate metabolites required by recurring changes in availability and use of the two different terminal electron chain acceptors, the bacterial one being oxygen. Oxygen won, and definitive loss of the archaeal membrane potential allowed permanent establishment of the bacterial partner as the proto‐mitochondrion, further metabolic integration and highly (...) efficient ATP production. This represents initial symbiogenesis, when crucial eukaryotic traits arose in response to the archaeon‐bacterium merger. The attendant generation of internal reactive oxygen species (ROS) gave rise to a myriad of further eukaryotic adaptations, such as extreme mitochondrial genome reduction, nuclei, peroxisomes and meiotic sex. Eukaryotic origins could have started with shuffling intermediate metabolites as is still essential today. (shrink)

How do questions concerning consciousness and phenomenal experience relate to, or interface with, questions concerning plans, knowledge and intentions? At least in the case of visual experience the relation, we shall argue, is tight. Visual perceptual experience, we shall argue, is fixed by an agent’s direct unmediated knowledge concerning her poise (or apparent poise) over a currently enabled action space. An action space, in this specific sense, is to be understood not as a fine-grained matrix of possibilities for bodily movement, (...) but as a matrix of possibilities for pursuing and accomplishing one’s intentional actions, goals and projects. If this is correct, the links between planning, intention and perceptual experience are tight, while (contrary to some recent accounts invoking the notion of ‘sensorimotor expectations’) the links between embodied activity and perceptual experience, though real, are indirect. What matters is not bodily activity itself, but our practical knowledge (which need not be verbalized or in any way explicit) of our own possibilities for action. Such knowledge, selected, shaped and filtered by the grid of plans, goals, and intentions, plays, we argue, a constitutive role in explaining the content and character of visual perceptual experience.

Recently, constructive neutral evolution has been touted as an important concept for the understanding of the emergence of cellular complexity. It has been invoked to help explain the development and retention of, amongst others, RNA splicing, RNA editing and ribosomal and mitochondrial respiratory chain complexity. The theory originated as a welcome explanation of isolated small scale cellular idiosyncrasies and as a reaction to ‘overselectionism’. Here I contend, that in its extended form, it has major conceptual problems, can not explain observed (...) patterns of complex processes, is too easily dismissive of alternative selectionist models, underestimates the creative force of complexity as such, and – if seen as a major evolutionary mechanism for all organisms – could stifle further thought regarding the evolution of highly complex biological processes.

In the 1950s, Noam Chomsky offered a new vision for linguistic research and syntacticians. This chapter explores some ways in which Chomsky's linguistic work has influenced research on one domain of linguistic performance, sentence processing, over the last half century. It shows that Chomsky's claim in Aspects of the Theory of Syntax is largely borne out: "the study of performance will proceed only as far as the study of the underlying competence permits". The chapter briefly addresses a question about the (...) scope of modern sentence processing research and its relationship to specific grammatical formalisms. It reviews the literature on incremental ambiguity resolution, moves to the processing of long‐distance filler‐gap dependency processing, and provides information on the processing of anaphoric relations. In order to illustrate how the phenomenon has contributed to psycholinguistic theorizing, the chapter outlines a well‐known model and then considers how other models diverge. (shrink)

Clinical research with adults who are unable to provide informed consent has the potential to improve understanding and care of a number of devasting conditions. This research also has the potential to exploit some of society's most vulnerable members.

Yet, there is widespread disagreement over which safeguards should be adopted. In the present paper, I consider to what extent (...) these disagreements can be resolved by appeal to a general account of the interests of subjects who are unable to consent and the conditions that must be satisfied for research enrollment to constitute exploitation of their inability to make their own decisions.
