Are interpersonal affordances a distinct type of affordance, and if so, what is it that differentiates them from other kinds of affordances? In this paper, I show that a hard distinction between interpersonal affordances and other affordances is warranted and ethically important. The enactivist theory of participatory sense-making demonstrates that there is a difference in coupling between agent-environment and agent-agent interactions, and these differences in coupling provide a basis for distinguishing between the perception of environmental and interpersonal affordances. Building further (...) on this foundation for understanding interpersonal affordances, I argue that in line with some enactivist work on social cognition, interpersonal affordances ought to be considered as those that are afforded by agents and are recognized as such. Given this distinction, I also make the point that because our social conventions establish persons as more than mere agents, the direct perception of interpersonal affordances may also involve seeing others as embodied selves. Distinguishing between types of affordances thus also matters ethically: there can be harms done when an agent is not perceived as an agent, and there can be harms done when an agent is not perceived as a self.

Non-representational approaches to cognition have struggled to provide accounts of long-term planning that forgo the use of representations. An explanation comes easier for cognitivist accounts, which hold that we concoct and use contentful mental representations as guides to coordinate a series of actions towards an end state. One non-representational approach, ecological-enactivism, has recently seen several proposals that account for “high-level” or “representation-hungry” capacities, including long-term planning and action coordination. In this paper, we demonstrate the explanatory gap in these accounts that (...) stems from avoiding the incorporation of long-term intentions, as they play an important role both in action coordination and perception on the ecological account. Using recent enactive accounts of language, we argue for a non-representational conception of intentions, their formation, and their role in coordinating pre-reflective action. We provide an account for the coordination of our present actions towards a distant goal, a skill we call distal engagement. Rather than positing intentions as an actual cognitive entity in need of explanation, we argue that we take them up in this way as a practice due to linguistically scaffolded attitudes towards language use.

In the wake of the spectacular success of Miranda Fricker's Epistemic Injustice, philosophers have paid a great deal of attention to testimonial injustice. Testimonial injustice occurs when recipients of testimony discount it in virtue of its source: usually, their social identity. The remedy for epistemic injustice is almost always listening better and giving greater weight to the testimony we hear, on most philosophers' implicit or explicit view. But Fricker identifies another kind of epistemic injustice: hermeneutical injustice. This kind of injustice (...) occurs when someone can't articulate their own experience or understand their situation for lack of the hermeneutical tools. There is a possible tension between these kinds of injustice, we suggest: sincere testimony may be misleading (may fail to identify significant harms the testfier is subject, or may fail to register its magnitude, or to categorize it as the kind of harm it is) in virtue of a lack of hermeneutical resources. This tension raises the possibility that there are situations in which experts - those who possess hermeneutical tools - may be able to correct the testimony of those who experience harms in virtue of their identity. In this paper, we identify possible cases in which epistemic injustice might be reduced through such correction: in which an increase in testimonial injustice might serve to decrease it in the longer run, for example. We also suggest how the obvious dangers of a too great readiness to see testimony as in need of expert correction might be mitigated, and how the expert might suggest corrections without ceasing to listen.

This paper details the ways that gender structures our senses of agency on an enactive framework. While it is common to discuss how gender influences higher, narrative levels of cognition, as with the formulation of goals and in considerations about our identities, it is less clear how gender structures our more immediate, embodied processes, such as the minimal sense of agency. While enactivists often acknowledge that gender and other aspects of our socio-cultural situatedness shape our cognitive processes, there is little (...) work on how this shaping takes place. In order to provide such an account, I will first look at the minimal and narrative senses of agency (Gallagher 2012), a distinction that draws from work on minimal and narrative selves (Zahavi 2010). Next I will explain the influence of the narrative sense of agency on the minimal sense of agency through work on intention-formation (Pacherie 2007). After a discussion of the role of gender in the narrative sense of agency, I’ll expand on work by Haslanger (2012) and Young (1980) to offer three ways in which gender influences the minimal sense of agency, showing the effect that gender has on how we perceive our possibilities for interaction in a phenomenologically immediate, pre-reflective manner.

The study of active matter systems demonstrates how interactions might co-constitute agential dynamics. Active matter systems are comprised of self-propelled independent entities which, en masse, take part in complex and interesting collective group behaviors at a far-from-equilibrium state (Menon, 2010 ; Takatori & Brady, 2015 ). These systems are modelled using very simple rules (Vicsek at al. 1995), which reveal the interactive nature of the collective behaviors seen from humble to highly complex entities. Here I show how the study of (...) active matter systems supports two related proposals regarding interaction and agency. First, I argue that the study of interactive dynamics in these systems evidences the utility of treating interaction as an ontological category (Longino, 2021 ) and challenges methodological individualism as the received explanatory primitive in the study of agency. Second, the methods used to research active matter systems demonstrate how a minimal approach to agency can scale up in studying interactive agential dynamics in more complex systems. The examples of coordination dynamics (Kelso, 2001 ) and participatory sense-making (De Jaegher & Di Paolo, 2007 ) are provided to show how understanding agency requires us to look beyond the individuals to the interactive agential dynamics that can guide, scaffold, or constrain their activity.

Enactivists frequently argue their account heralds a revolution in cognitive science: enactivism will unseat cognitivism as the dominant paradigm. We examine the lines of reasoning enactivists employ in stirring revolt, but show that none of these prove compelling reasons for cognitivism to be replaced by enactivism. First, we examine the hard sell of enactivism: enactivism reveals a critical explanatory gap at the heart of cognitivism. We show that enactivism does not meet the requirements to incite a paradigm shift in the (...) Kuhnian sense—there is no internal crisis in cognitivism. Nor does it provide inherently better explanations of cognition as some have claimed. Second, we consider the soft sell of enactivism: enactivism provides a more attractive, parsimonious, or clear-eyed lens on cognition. This move proves to boil down to a misunderstanding of how theories are selected in science. Instead we lend support to a broader and more desirable way to conceive of enactivism, the recent proposal that enactivism is a philosophy of nature. We explain how a philosophy of nature does more than support a single research paradigm by integrating scientific questions into a cohesive picture. (shrink)

Active materials are self-propelled non-living entities which, in some circumstances, exhibit a number of cognitively interesting behaviors such as gradient-following, avoiding obstacles, signaling and group coordination. This has led to scientific and philosophical discussion of whether this may make them useful as minimal models of cognition (Hanczyc, 2014; McGivern, 2019). Batterman and Rice (2014) have argued that what makes a minimal model explanatory is that the model is ultimately in the same universality class as the target system, which underpins why (...) it exhibits the same macrobehavior. We appeal to recent research in basal cognition (Lyon et al., 2021) to establish appropriate target systems and essential features of cognition as a target of modeling. Looking at self-propelled oil droplets, a type of active material, we do not find that organization alone indicates that these systems exhibit the essential features of cognition. We then examine the specific behaviors of oil droplets but also fail to find that these demonstrate the essential features of cognition. Without a universality class, Batterman & Rice’s account of the explanatory power of minimal models simply does not apply to cognition. However, we also want to stress that it is not intended to; cognition is not the same type of behavioral phenomena as those found in physics. We then look to the minimal cognition methodology of Beer (1996, 2020a, b) to show how active materials can be explanatorily valuable regardless of their cognitive status because they engage in specific behaviors that have traditionally been expected to involve internal representational dynamics, revealing misconceptions about the cognitive underpinnings of certain, specific behaviors in target systems where such behaviors are cognitive. Further, Beer’s models can also be genuinely explanatory by providing dynamical explanations. (shrink)

Feminist philosophers of science have long discussed the importance of taking situatedness into account in scientific practices to avoid erasing important aspects of lived experience. Through the example of Gillian Einstein’s [2012] situated neuroscience, I will add support to Gallagher’s [2019] claims that intertheoretic reduction is problematic and provide reason to think pluralistic methodologies are explanatorily and ethically preferable.

Open peer commentary on the article “Beyond Individual-Centred 4E Cognition: Systems Biology and Sympoiesis” by Mads Julian Dengsø & Michael David Kirchhoff. Abstract: I provide two reasons for thinking the conclusion drawn from the argument’s premises is too strong. Briefly, (a) the benefits of having consistent commitments between enactivism and developmental systems theory are only clear when treating both as philosophies of nature rather than empirical research programs, and (b) the target article demonstrates that enactivism is capable of explanatory pluralism.

Our target article concerns the direction and growth of enactivism, a framework portrayed as a revolutionary shift in understanding cognition. While enactivism continues to be a lively position, it is unclear how its contributions relate to the cognitive sciences. Despite some empirical successes, enactivism remains somewhat insulated as a theoretical position and as a research program. There exists a discrepancy between enactivist aims and delivery. The basis of this problem, we argue, is that the overall objective of enactive theorising is (...) not clear, which has led to diverging strategies for implementation and integration with the cognitive sciences. We review contributions from different strains of enactivism – autopoietic, sensorimotor and radical – and their research goals, both tacit and explicit. We show that enactivism is productively understood as two projects we term utopian enactivism and scientific enactivism. Utopian enactivism aims to develop a philosophically defensible lens through which cognitive science is to be viewed. Scientific enactivism intervenes in scientific practice by contributing to the implementation of enactive ideas. Once disentangled, the utopian and scientific projects have important but independent tasks. Utopian enactivism is useful for building a coherent and defensible enactive philosophy of nature, while scientific enactivism is free to draw upon and contribute to non-enactive approaches in the cognitive sciences. We aim to motivate discussions that will enhance enactivism’s progress, and our reappraisal also offers a clear and explicit roadmap for renewing advances in enactivist philosophy and cognitive science.

Affordances are standardly understood as perceived possibilities for interaction. What is afforded is in turn regarded as dependent on the properties of a body and its environment. Human bodies are nearly ubiquitously clothed, and clothing can change the capabilities of bodies. We argue that when clothing does this, it should be regarded as an affordance transforming technology. Clothing receives passing attention in remarks by Gibson, and some empirical work in ecological psychology uses worn items as experimental manipulations. We argue that (...) the effects of clothing should be a central topic of investigation. We further show how the notion of clothing as an affordance transforming technology allows ecological psychology to accommodate feminist insights about the restrictive or oppressive nature of some gendered clothing norms. We aim to show that if ecological psychology is to be a general framework for thinking about human perception and activity, then it should consider clothing, because of the differences it can make to what is afforded. It should do so critically because the ways that clothing transforms affordances are sometimes discriminating in that what people are expected to wear and what differences that makes aren’t independent of how they’re classified in systems of power and oppression.

I develop a broadly reliabilist theory of non-ideal epistemic rationality and argue that if it is correct we should reject the recently popular idea that the standards of non-ideal epistemic rationality are mere social conventions.

To what extent should we use technological advances to try to make better human beings? Leading philosophers debate the possibility of enhancing human cognition, mood, personality, and physical performance, and controlling aging. Would this take us beyond the bounds of human nature? These are questions that need to be answered now.

In the Aristotelian tradition, the psychological difference between virtue and continence is commonly understood in terms of inner harmony versus inner conflict. Virtuous agents experience inner harmony between feeling and action because they do not care to do other than what their circumstances call for, whereas continent agents feel conflicted about doing what is called for because of competing concerns. Critics of this view argue, however, that when the circumstances require sacrificing something of genuine value, virtuous agents can indeed feel (...) conflicted about acting well. But if this is so, what differentiates virtuous from merely continent agency? This essay argues that the traditional distinction conflates two aspects of virtue as well as two species of continence. And distinguishing between them provides resources for making sense of the complex relationship between inner conflict and good moral agency. (shrink)

I argue that at least one of the following propositions is true: the human species is very likely to become extinct before reaching a ’posthuman’ stage; any posthuman civilization is extremely unlikely to run a significant number of simulations of its evolutionary history ; we are almost certainly living in a computer simulation. It follows that the belief that there is a significant chance that we shall one day become posthumans who run ancestor-simulations is false, unless we are currently living (...) in a simulation.

_Anthropic Bias_ explores how to reason when you suspect that your evidence is biased by "observation selection effects"--that is, evidence that has been filtered by the precondition that there be some suitably positioned observer to "have" the evidence. This conundrum--sometimes alluded to as "the anthropic principle," "self-locating belief," or "indexical information"--turns out to be a surprisingly perplexing and intellectually stimulating challenge, one abounding with important implications for many areas in science and philosophy. There are the philosophical thought experiments and paradoxes: (...) the Doomsday Argument; Sleeping Beauty; the Presumptuous Philosopher; Adam & Eve; the Absent-Minded Driver; the Shooting Room. And there are the applications in contemporary science: cosmology ; evolutionary theory ; the problem of time's arrow ; quantum physics ; game-theory problems with imperfect recall ; even traffic analysis. _Anthropic Bias_ argues that the same principles are at work across all these domains. And it offers a synthesis: a mathematically explicit theory of observation selection effects that attempts to meet scientific needs while steering clear of philosophical paradox. (shrink)

Our paradigms of aesthetic value condition the philosophical questions we pose and hope to answer about it. Theories of aesthetic value are typically individualistic, in the sense that the paradigms they are designed to capture, and the questions to which they are offered as answers, center the individual’s engagement with aesthetic value. Here I offer some considerations that suggest that such individualism is a mistake and sketch a communitarian way of posing and answering questions about the nature of aesthetic value.

The human brain has some capabilities that the brains of other animals lack. It is to these distinctive capabilities that our species owes its dominant position. Other animals have stronger muscles or sharper claws, but we have cleverer brains. If machine brains one day come to surpass human brains in general intelligence, then this new superintelligence could become very powerful. As the fate of the gorillas now depends more on us humans than on the gorillas themselves, so the fate of (...) our species then would come to depend on the actions of the machine superintelligence. But we have one advantage: we get to make the first move. Will it be possible to construct a seed AI or otherwise to engineer initial conditions so as to make an intelligence explosion survivable? How could one achieve a controlled detonation? To get closer to an answer to this question, we must make our way through a fascinating landscape of topics and considerations. Read the book and learn about oracles, genies, singletons; about boxing methods, tripwires, and mind crime; about humanity's cosmic endowment and differential technological development; indirect normativity, instrumental convergence, whole brain emulation and technology couplings; Malthusian economics and dystopian evolution; artificial intelligence, and biological cognitive enhancement, and collective intelligence.

I argue that eating meat is morally good and our duty when it is part of a practice that has benefited animals. The existence of domesticated animals depends on the practice of eating them, and the meat-eating practice benefits animals of that kind if they have good lives. The argument is not consequentialist but historical, and it does not apply to nondomesticated animals. I refine the argument and consider objections.

This book explores both the embodied nature of social life and the social nature of human bodily life. It provides an accessible review of the contemporary social science debates on the body, and develops a coherent new perspective.

He draws on theoretical insights from the work of Gilbert Ryle, Maurice Merleau-Ponty, George Herbert Mead and Pierre Bourdieu, and shows how the work of (...) these writers overlaps in interesting and important ways which, when combined, provide the basis for a persuasive and robust account of human embodiment. The Social Body provides a timely review of the theoretical approaches to the sociology of the body. It offers new insights, and a coherent new perspective on the body. It will be valuable reading for students and academics in sociology, philosophy, anthropology, psychology, and cultural studies. (shrink)

A theory of aesthetic value should explain what makes aesthetic value good. Current views about what makes aesthetic value good privilege the individual’s encounter with aesthetic value—listening to music, reading a novel, writing a poem, or viewing a painting. What makes aesthetic value good is its benefit to the individual appreciator. But engagement with aesthetic value is often a social, participatory matter: sharing and discussing aesthetic goods, imitating aesthetic agents, dancing, cooking, dining, or making music together. This article argues that (...) we should understand aesthetic value in a way that centers these social forms of aesthetic engagement. To this end, the article argues that there is a social practice of aesthetic valuing, characterized as a participatory practice governed by the value of aesthetic community, which engages us in the social development of our capacities for discretionary valuing and volitional openness. Current theories of aesthetic value have trouble capturing the character of the practice of aesthetic valuing, and this motivates a novel communitarian theory of aesthetic value: aesthetic value is what is worthy of engagement in the social practice of aesthetic valuing.

In this article, I argue that God is authoritative over us because he is our divine, causal parent. As our causal parent, God has duties to relate to us, but he can only fulfill those duties if he has the practical authority to give us commands aimed at our sanctification.

After I make this argument, I show how the view has significant advantages over extant arguments for divine authority and can (...) help solve other significant problems in philosophy of religion.

It is common to allocate scarce health care resources by maximizing QALYs per dollar. This approach has been attacked by disability-rights advocates, policy-makers, and ethicists on the grounds that it unjustly discriminates against the disabled. The main complaint is that the QALY-maximizing approach implies a seemingly unsatisfactory conclusion: other things being equal, we should direct life-saving treatment to the healthy rather than the disabled. This argument pays insufficient attention to the downsides of the potential alternatives. We show that this sort (...) of discrimination is one of four unpalatable consequences that any approach to priority setting in health care must face. We argue that, given the alternatives, it is far from clear that we should revise the QALY-maximizing approach in response to this objection. (shrink)

It is intuitively plausible that art and imagination are intimately connected. This chapter explores attempts to explain that connection. We focus on three areas in which art and imagination might be linked: production, ontology, and appreciation. We examine views which treat imagination as a fundamental human faculty, and aim for comprehensive accounts of art and artistic practice: for example, those of Kant and Collingwood. We also discuss philosophers who argue that a specific kind of imagining may explain some particular element (...) of the artistic domain: for example, Walton's ideas about representational art, and Kivy’s about reading.

Philosophers often characterize discourse in general as aiming at some sort of convergence (in beliefs, plans, dispositions, feelings, etc.), and many views about aesthetic discourse in particular affirm this thought. I argue that a convergence norm does not govern aesthetic discourse. The conversational dynamics of aesthetic discourse suggest that typical aesthetic claims have directive force. I distinguish between dynamic and illocutionary force and develop related theories of each for aesthetic discourse. I argue that the illocutionary force of aesthetic utterances is (...) typically invitational because its dynamic force is influenced by a ‘communal’ norm. I draw on dynamic pragmatics to develop a formal account of this dynamic force that explains why invitation has pride of place in aesthetic conversation. It turns out that the end of aesthetic discourse is not convergence but a distinctive form of community, a kind of harmony of individuality, that is compatible with aesthetic disagreement. If this is right, then convergence theories of aesthetic and normative discourse, and of conversation in general, need to be revised. (shrink)

Articulate and perceptive, Intersubjectivity is a text that explains the notions of intersubjectivity as a central concern of philosophy, sociology, psychology, and politics.

A dizzying trip through the mind(s) of the provocative and influential thinker Nick Land. During the 1990s British philosopher Nick Land's unique work, variously described as “rabid nihilism,” “mad black deleuzianism,” and “cybergothic,” developed perhaps the only rigorous and culturally-engaged escape route out of the malaise of “continental philosophy” —a route that was implacably blocked by the academy. However, Land's work has continued to exert an influence, both through the British “speculative realist” philosophers who studied with him, and (...) through the many cultural producers—writers, artists, musicians, filmmakers—who have been invigorated by his uncompromising and abrasive philosophical vision. Beginning with Land's early radical rereadings of Heidegger, Nietzsche, Kant and Bataille, the volume collects together the papers, talks and articles of the mid-90s—long the subject of rumour and vague legend (including some work which has never previously appeared in print)—in which Land developed his futuristic theory-fiction of cybercapitalism gone amok; and ends with his enigmatic later writings in which Ballardian fictions, poetics, cryptography, anthropology, grammatology and the occult are smeared into unrecognisable hybrids. Fanged Noumena gives a dizzying perspective on the entire trajectory of this provocative and influential thinker's work, and has introduced his unique voice to a new generation of readers. (shrink)

Social networking sites have challenged ethical issues about users’ information security and privacy. SNS users are concerned about their privacy and need to control the information they share and its use. This paper examines the security of SNS by taking a look at the influence of users’ perceived control of information over their information-sharing behaviors. Employing an empirical study, this paper demonstrates the importance of perceived control in SNS users’ information-sharing behaviors. Specifically, perceived control has been found to be negatively (...) related to perceived privacy risk and attitude toward information sharing, which in turn has an impact on their information-sharing behaviors. In addition, gender has been shown to be an important factor that moderates the influences of both perceived control and perceived privacy risk on SNS users’ attitudes toward information sharing. Theoretical and practical implications are discussed. (shrink)

This article responds to recent debates in critical algorithm studies about the significance of the term “algorithm.” Where some have suggested that critical scholars should align their use of the term with its common definition in professional computer science, I argue that we should instead approach algorithms as “multiples”—unstable objects that are enacted through the varied practices that people use to engage with them, including the practices of “outsider” researchers. This approach builds on the work of Laura Devendorf, Elizabeth Goodman, (...) and Annemarie Mol. Different ways of enacting algorithms foreground certain issues while occluding others: computer scientists enact algorithms as conceptual objects indifferent to implementation details, while calls for accountability enact algorithms as closed boxes to be opened. I propose that critical researchers might seek to enact algorithms ethnographically, seeing them as heterogeneous and diffuse sociotechnical systems, rather than rigidly constrained and procedural formulas. To do so, I suggest thinking of algorithms not “in” culture, as the event occasioning this essay was titled, but “as” culture: part of broad patterns of meaning and practice that can be engaged with empirically. I offer a set of practical tactics for the ethnographic enactment of algorithmic systems, which do not depend on pinning down a singular “algorithm” or achieving “access,” but which rather work from the partial and mobile position of an outsider.

'The Probabilistic Mind' is a follow-up to the influential and highly cited 'Rational Models of Cognition'. It brings together developments in understanding how, and how far, high-level cognitive processes can be understood in rational terms, and particularly using probabilistic Bayesian methods.

The standard interpretation of cognitive reflection tests assumes that correct responses are reflective and lured responses are unreflective. However, prior process-tracing of mathematical reflection tests has cast doubt on this interpretation. In two studies (N = 201), we deployed a validated think-aloud protocol in-person and online to test how this assumption is satisfied by the new, validated, less familiar, and less mathematical verbal Cognitive Reflection Test (vCRT). Importantly, thinking aloud did not disrupt test performance compared to a control group. Moreover, (...) verbalized thoughts in both studies revealed that most (but not all) correct responses involved reflection and that most (but not all) lured responses lacked reflection. These data suggest that the vCRT usually satisfies the standard interpretation of the reflection tests (albeit not without exceptions) and that the vCRT can be a good measure of the construct theorized by the two-factor explication of ‘reflection’ (as deliberate and conscious).

This commentary focuses on the claim that perceptual demands have caused the linearity exhibited by locus equations.

Contemporary philosophical attitudes toward beauty are hard to reconcile with its importance in the history of philosophy. Philosophers used to allow it a starring role in their theories of autonomy, morality, or the good life. But today, if beauty is discussed at all, it is often explicitly denied any such importance. This is due, in part, to the thought that beauty is the object of “disinterested pleasure”. In this paper I clarify the notion of disinterest and develop two general strategies (...) for resisting the emphasis on it, in the hopes of getting a clearer view of beauty’s significance. I present and discuss several literary depictions of the encounter with beauty that motivate both strategies. These depictions illustrate the ways in which aesthetic experience can be personally transformative. I argue that they present difficulties for disinterest theories and suggest we abandon the concept of disinterest to focus instead on the special kind of interest beauty fuels. I propose a closer look at the Platonic thought that beauty is the object of love. (shrink)

The terms "imagination'' and "imaginative'' can be readily applied to a profusion of attitudes, experiences, activities, and further phenomena. The heterogeneity of the things to which they're applied prompts the thoughts that the terms are polysemous, and that there is no single, coherent, fruitful conception of imagination to be had. Nonetheless, much recent work on imagination ascribes implicitly to a univocal way of thinking about imaginative phenomena: the imitation theory, according to which imaginative experiences imitate other experiences. This approach is (...) infelicitous. It issues in unhelpful descriptions of imaginative activities, experiences, and attitudes, and frustrates theorizing about imagination's applications and intensional characteristics. A better way of thinking about imagination is the lens theory, according to which the imagination is a set of ways to focus, refine, clarify or concentrate the matter of other experiences. This approach offers better characterizations of imaginative phenomena, and promises brighter theoretical illumination of them. (shrink)

Remarkable progress in the mathematics and computer science of probability has led to a revolution in the scope of probabilistic models.

Despite thermodynamic, bioenergetic and phylogenetic failings, the 81‐year‐old concept of primordial soup remains central to mainstream thinking on the origin of life. But soup is homogeneous in pH and redox potential, and so has no capacity for energy coupling by chemiosmosis. Thermodynamic constraints make chemiosmosis strictly necessary for carbon and energy metabolism in all free‐living chemotrophs, and presumably the first free‐living cells too. Proton gradients form naturally at alkaline hydrothermal vents and are viewed as central to the origin of life. (...) Here we consider how the earliest cells might have harnessed a geochemically created proton‐motive force and then learned to make their own, a transition that was necessary for their escape from the vents. Synthesis of ATP by chemiosmosis today involves generation of an ion gradient by means of vectorial electron transfer from a donor to an acceptor. We argue that the first donor was hydrogen and the first acceptor CO2. (shrink)
