Brains, it has recently been argued, are essentially prediction machines. They are bundles of cells that support perception and action by constantly attempting to match incoming sensory inputs with top-down expectations or predictions. This is achieved using a hierarchical generative model that aims to minimize prediction error within a bidirectional cascade of cortical processing. Such accounts offer a unifying model of perception and action, illuminate the functional role of attention, and may neatly capture the special contribution of cortical processing to (...) adaptive success. This target article critically examines this approach, concluding that it offers the best clue yet to the shape of a unified science of mind and action. Sections 1 and 2 lay out the key elements and implications of the approach. Section 3 explores a variety of pitfalls and challenges, spanning the evidential, the methodological, and the more properly conceptual. The paper ends (sections 4 and 5) by asking how such approaches might impact our more general vision of mind, experience, and agency. (shrink)

I distinguish two theses regarding technological successors to current humans (posthumans): an anthropologically bounded posthumanism (ABP) and an anthropologically unbounded posthumanism (AUP). ABP proposes transcendental conditions on agency that can be held to constrain the scope for “weirdness” in the space of possible posthumans a priori. AUP, by contrast, leaves the nature of posthuman agency to be settled empirically (or technologically). Given AUP there are no “future proof” constraints on the strangeness of posthuman agents. -/- In Posthuman Life I defended (...) AUP via a critique of Donald Davidson’s work on intentionality and a “naturalistic deconstruction” of transcendental phenomenology (See also Roden 2013). In this paper I extend this critique to Robert Brandom’s account of the relationship between normativity and intentionality in Making It Explicit (MIE) and in other writings. -/- Brandom’s account understands intentionality in terms of the capacity to undertake and ascribe inferential normative commitments. It makes “first class agency” dependent on the ability to participate in discursive social practices. It implies that posthumans – insofar as they qualify as agents at all – would need to be social and discursive beings. -/- The problem with this approach, I will argue, is that it replicates a problem that Brandom discerns in Dennett’s intentional stance approach. It tells us nothing about the conditions under which a being qualifies as a potential interpreter and thus little about the conditions for meaning, understanding or agency. -/- I support this diagnosis by showing that Brandom cannot explain how a non-sapient community could bootstrap itself into sapience by setting up a basic deontic scorekeeping system without appealing (along with Davidson and Dennett) to the ways in which an idealized observer would interpret their activity. -/- This strongly suggests that interpretationist and pragmatist accounts cannot explain the semantic or the intentional without regressing to assumptions about ideal interpreters or background practices whose scope they are incapable of delimiting. It follows that Anthropologically Unbounded Posthumanism is not seriously challenged by the claim that agency and meaning are “constituted” by social practices. -/- AUP implies that we can infer no claims about the denizens of “Posthuman Possibility Space” a priori, by reflecting on the pragmatic transcendental conditions for semantic content. We thus have no reason to suppose that posthuman agents would have to be subjects of discourse or, indeed, members of communities. The scope for posthuman weirdness can be determined by recourse to engineering alone. (shrink)

Musical improvisation is a natural case of human pattern formation, and Walton and colleagues investigate the way that different contextual constraints affect patterns of improvisation and their aesthetic quality. The authors find that coordination patterns are more diversified between two musicians when the musical space in which to improvise is relatively more constrained. They also find that listeners experience more diversified, complementary patterns between musicians as more enjoyable and harmonious.

Phenomenology is based on a doctrine of evidence that accords a crucial role to the human capacity to conceptualise or ‘intuit’ features of their experience. However, there are grounds for holding that some experiential entities to which phenomenologists are committed must be intuition-transcendent or ‘dark’. Examples of dark phenomenology include the very fine-grained perceptual discriminations which Thomas Metzinger calls ‘Raffman Qualia’ and, crucially, the structure of temporal awareness. It can be argued, on this basis, that phenomenology is in much the (...) same epistemological relationship to its own subject matter as descriptive (i.e. ‘phenomenological’) physics or biology are to physical and biological reality: phenomenology cannot tell us what phenomenology is really ‘about’. This does not mean we should abjure phenomenology. It implies, rather, that the domain of phenomenology is not the province of a self-standing, autonomous discipline but must be investigated with any empirically fruitful techniques that are open to us (e.g. computational neuroscience, artificial intelligence, etc.). Finally, it entails that while a naturalized phenomenology should be retained as a descriptive, empirical method, it should not be accorded transcendental authority. (shrink)

We distinguish between three philosophical views on the neuroscience of predictive models: predictive coding, predictive processing and predictive engagement. We examine the concept of active inference under each model and then ask how this concept informs discussions of social cognition. In this context we consider Frith and Friston’s proposal for a neural hermeneutics, and we explore the alternative model of enactivist hermeneutics.

The idea that perceptual and cognitive systems must incorporate knowledge about the structure of the environment has become a central dogma of cognitive theory. In a Bayesian context, this idea is often realized in terms of “tuning the prior”—widely assumed to mean adjusting prior probabilities so that they match the frequencies of events in the world. This kind of “ecological” tuning has often been held up as an ideal of inference, in fact defining an “ideal observer.” But widespread as this (...) viewpoint is, it directly contradicts Bayesian philosophy of probability, which views probabilities as degrees of belief rather than relative frequencies, and explicitly denies that they are objective characteristics of the world. Moreover, tuning the prior to observed environmental frequencies is subject to overfitting, meaning in this context overtuning to the environment, which leads (ironically) to poor performance in future encounters with the same environment. Whenever there is uncertainty about the environment—which there almost always is—an agent's prior should be biased away from ecological relative frequencies and toward simpler and more entropic priors.

What would something unlike us--a chimpanzee, say, or a computer--have to be able to do to qualify as a possible knower, like us? To answer this question at the very heart of our sense of ourselves, philosophers have long focused on intentionality and have looked to language as a key to this condition. Making It Explicit is an investigation into the nature of language--the social practices that distinguish us as rational, logical creatures--that revises the very terms of this inquiry. Where (...) accounts of the relation between language and mind have traditionally rested on the concept of representation, this book sets out an alternate approach based on inference, and on a conception of certain kinds of implicit assessment that become explicit in language. Making It Explicit is the first attempt to work out in detail a theory that renders linguistic meaning in terms of use--in short, to explain how semantic content can be conferred on expressions and attitudes that are suitably caught up in social practices. -/- At the center of this enterprise is a notion of discursive commitment. Being able to talk--and so in the fullest sense being able to think--is a matter of mastering the practices that govern such commitments, being able to keep track of one’s own commitments and those of others. Assessing the pragmatic significance of speech acts is a matter of explaining the explicit in terms of the implicit. As he traces the inferential structure of the social practices within which things can be made conceptually explicit, the author defines the distinctively expressive role of logical vocabulary. This expressive account of language, mind, and logic is, finally, an account of who we are. (shrink)

How is it that thoroughly physical material beings such as ourselves can think, dream, feel, create and understand ideas, theories and concepts? How does mere matter give rise to all these non-material mental states, including consciousness itself? An answer to this central question of our existence is emerging at the busy intersection of neuroscience, psychology, artificial intelligence, and robotics.In this groundbreaking work, philosopher and cognitive scientist Andy Clark explores exciting new theories from these fields that reveal minds like ours to (...) be prediction machines - devices that have evolved to anticipate the incoming streams of sensory stimulation before they arrive. These predictions then initiate actions that structure our worlds and alter the very things we need to engage and predict. Clark takes us on a journey in discovering the circular causal flows and the self-structuring of the environment that define "the predictive brain." What emerges is a bold, new, cutting-edge vision that reveals the brain as our driving force in the daily surf through the waves of sensory stimulation. (shrink)

Influential philosopher Michel Serres’s foundational work uses fable to explore how human relations are identical to that of the parasite to the host body. Among Serres’s arguments is that by being pests, minor groups can become major players in public dialogue—creating diversity and complexity vital to human life and thought. Michel Serres is professor in history of science at the Sorbonne, professor of Romance languages at Stanford University, and author of several books, including _Genesis._ Lawrence R. Schehr is professor of (...) French at the University of Illinois, Urbana-Champaign. Cary Wolfe is Bruce and Elizabeth Dunlevie Professor of English at Rice University. His books include _Zoontologies: The Question of the Animal _. (shrink)

We imagine posthumans as humans made superhumanly intelligent or resilient by future advances in nanotechnology, biotechnology, information technology and cognitive science. Many argue that these enhanced people might live better lives; others fear that tinkering with our nature will undermine our sense of our own humanity. Whoever is right, it is assumed that our technological successor will be an upgraded or degraded version of us: Human 2.0. Posthuman Life argues that the enhancement debate projects a human face onto an empty (...) screen. We do not know what will happen and, not being posthuman, cannot anticipate how posthumans will assess the world. If a posthuman future will not necessarily be informed by our kind of subjectivity or morality the limits of our current knowledge must inform any ethical or political assessment of that future. Posthuman Life develops a critical metaphysics of posthuman succession and argues that only a truly speculative posthumanism can support an ethics that meets the challenge of the transformative potential of technology.

A new theory is taking hold in neuroscience. It is the theory that the brain is essentially a hypothesis-testing mechanism, one that attempts to minimise the error of its predictions about the sensory input it receives from the world. It is an attractive theory because powerful theoretical arguments support it, and yet it is at heart stunningly simple. Jakob Hohwy explains and explores this theory from the perspective of cognitive science and philosophy. The key argument throughout The Predictive Mind is (...) that the mechanism explains the rich, deep, and multifaceted character of our conscious perception. It also gives a unified account of how perception is sculpted by attention, and how it depends on action. The mind is revealed as having a fragile and indirect relation to the world. Though we are deeply in tune with the world we are also strangely distanced from it. (shrink)

Where much contemporary philosophy seeks to stave off the "threat" of nihilism by safeguarding the experience of meaning--characterized as the defining feature of human existence--from the Enlightenment logic of disenchantment, this book attempts to push nihilism to its ultimate conclusion by forging a link between revisionary naturalism in Anglo-American philosophy and anti-phenomenological realism in recent French philosophy. Contrary to an emerging "post-analytic" consensus which would bridge the analytic-continental divide by uniting Heidegger and Wittgenstein against the twin perils of scientism and (...) skepticism, this book short-circuits both traditions by plugging eliminative materialism directly into speculative realism.

Drawing from Michel Serres’ notion of the parasite, this article provides a nuanced explanation for noise that distinguishes itself from prevailing negative narratives, which often seek to define noise as unwanted, undesirable or damaging sound. Such narratives have left noise vulnerable to moralising polemics, which construct silence and noise as a dichotomy between the past and present, natural and cultural, relaxing and disturbing, and, fundamentally, good and bad. This article facilitates a reconsideration of noise’s ethical connotations by proposing the notion (...) of noise as affect. (shrink)
