The first of these two small works contains the text of the Riddell Memorial Lectures, while the second contains the text of the Twelfth Eddington Memorial Lecture. There is no doubt that Sir Russell Brain is on the side of the angels, at any rate in intention, in both these works. The professional philosopher will be slightly embarrassed however at the prospect of more and more scientists taking their stand with the angels for the wrong reasons. Both these (...) works are concerned with the epistemological problem, and also therefore with the psychological problem, of perception. The first assumes that the sensory qualities of normal perception, such as colours, sounds, smells and touches, are generated by the brain of the percipient and are unlike those external events which constitute the states of objects by which they are caused. “The facts of physics and physiology show that perception is the end–result of a series of physical events, the last of which, a state of activity of the brain of the percipient, differs so completely from the events occurring in the object perceived that the qualitative features of a percept can have no resemblance to the physical object which it represents”.

I much appreciate the honour of being invited to deliver the first Manson lecture, which, its founder has laid down, is to be devoted to the consideration of some subject of common interest to philosophy and medicine. I cannot think of anything which better fulfils that condition than the neurological approach to the problem of perception. The neurologist holds the bridge between body and mind. Every day he meets with examples of disordered perception and he learns from observing the effects (...) of lesions produced by disease, or by the physiologist's experiments, something of how the neural basis of perception is organized. It is possible to study perception as though this was largely irrelevant. How far that view is right will be for you to judge when I have finished. (shrink)

Bertrand Russell may not have been aware of it, but he wrote part of the dossier that was submitted on his behalf for the Nobel Peace Prize. Before he had turned from the Campaign for Nuclear Disarmament to the Committee of 100 and subsequent campaigns of the 1960s, his wife, Edith, was asked by his publisher, Sir Stanley Unwin, for an account of his work for peace. This document was likely used a few months later in Joseph Rotblat's submission (...) of Russell's name to the Norwegian Nobel Peace Prize committee. (shrink)

"Well-publicized research in psychology tells us that over half of our attempts to change habitual behavior fail within one year. Even without reading the research, most of us will intuitively sense the truth in this, as we have all tried and failed to rid ourselves of one bad habit or another. The human story of habits and the difficulty of change has been told in many books - most of which will make only a quick reference to dopamine or the (...) "lizard brain" before moving on to practical tips and tricks for behavior change. In contrast, Stuck: The Neuroscience of Why Changing Our Behavior is So Hard will tell the brain's story about why behavior is so hard to change. Russell Poldrack offers an in-depth, yet entirely accessible, guide to the neuroscientific research on habits and habit change. Part I introduces the "anatomy of a habit," starting with the argument that the resilience of our habits stems largely from a mismatch between the environment in which our brains evolved and the one in which we now live, and continuing on to introduce current work on fear and anxiety, motivation, and cognitive control that bears on habit formation. Part II focuses on what neuroscience can tell us about breaking habits, introducing evidence-based strategies that give us the best possible chance to break cycles of bad behavior. Throughout the book, Poldrack offers a clear-eyed view of what neuroscience can tell us about habit change, and what it cannot - and importantly, how we know what we know"--. (shrink)

In his novel Remembrance of Things Past, Marcel Proust argues that conventional descriptions of the phenomenology of consciousness are incomplete because they focus too much on the highly-salient sensory information that dominates each moment of awareness and ignore the network of associations that lies in the background. In this paper, I explicate Proust’s theory of conscious experience and show how it leads him directly to a theory of aesthetic perception. Proust’s division of awareness into two components roughly corresponds to William (...) James’ division of the stream of thought into a “nucleus” and “fringe.” Proust argues that the function of art is to evoke the underlying associative network indirectly in the mind of the observer by using carefully chosen sensory surfaces to control the stream of thought. I propose a possible neural basis for this Proustian/Jamesian phenomenology, and argue that the general principles of Proustian aesthetics can be applied to all forms of art. I conclude that a scientific theory of art should follow in a straightforward manner from a scientific theory of consciousness. (shrink)

Neuroscientists now approach some of the deepest problems of the human condition - from illnesses and disorders such as Alzheimer's disease and schizophrenia, to the search for the nature of consciousness itself - in the belief that their science can say something useful about these processes and how to intervene in them. At the same time, by addressing the biological mechanisms involved in phenomena as varied as street violence, drug addiction and sexual orientation, the new science raises profound ethical, legal, (...) social and medical questions. Over many of these issues there is no clear consensus but rather, intense debate. Is memory a molecular process? Is schizophrenia a genetic disorder? What does the future hold for psychopharmacology? Can consciousness be computed and is artificial intelligence a real prospect? From Brains to Consciousness? brings together fourteen of the world's leading neuroscientists, psychologists, computer modellers and philosophers, in a series of chapters that offer fascinating and up-to-the-minute insight into the debates that are taking place in this exciting area of research.

Many debates about the moral status of things—for example, debates about the natural rights of human fetuses or nonhuman animals—eventually migrate towards a discussion of the capacities of the things in question—for example, their capacities to feel pain, think, or love. Yet the move towards capacities is often controversial: if a human’s capacities are the basis of its moral status, how could a human having lesser capacities than you and I have the same "serious" moral status as you and I? (...) This book answers this question by arguing that if something is human, it has a set of typical human capacities; that if something has a set of typical human capacities, it has serious moral status; and thus all human beings have the same sort of serious moral status as you and I. Beginning from what our common intuitions tell us about situations involving "temporary incapacitation"—where a human organism has, then loses, then regains a certain capacity—this book argues for substantive conclusions regarding human fetuses and embryos, humans in a permanent vegetative state, humans suffering from brain diseases, and humans born with genetic disorders. Since these conclusions must have some impact on our ongoing moral and political debates about the proper treatment of such humans, this book will be useful to professionals and students in philosophy, bioethics, law, medicine, and public policy.

On a remarkably thin base of evidence – largely the spectral analysis of points of light – astronomers possess, or appear to possess, an abundance of knowledge about the structure and history of the universe. We likewise know more than might even have been imagined a few centuries ago about the nature of physical matter, about the mechanisms of life, about the ancient past. Enormous theoretical and methodological ingenuity has been required to obtain such knowledge; it does not invite easy (...) discovery by the untutored. It may seem odd, then, that we have so little scientific knowledge of what lies closest at hand, apparently ripe for easy discovery, and of greatest importance for our quality of life: our own conscious experience – our sensory experiences and pains, for example, our inner speech and imagery, our felt emotion. Scientists know quite a bit about human visual capacities and the brain processes involved in vision, much less about the subjective experience of seeing; a fair bit about the physiology of emotion, almost nothing about its phenomenology. Philosophers began in earnest in the seventeenth and eighteenth centuries to describe and classify our patterns of conscious experience. John Locke, for instance, divided experienced “ideas” into those that arise from sensation and those that arise from reflection, and he began to classify them into. (shrink)

William James described the stream of thought as having two components: (1) a nucleus of highly conscious, often perceptual material; and (2) a fringe of dimly felt contextual information that controls the entry of information into the nucleus and guides the progression of internally directed thought. Here I examine the neural and cognitive correlates of this phenomenology. A survey of the cognitive neuroscience literature suggests that the nucleus corresponds to a dynamic global buffer formed by interactions between different regions of (...) the brain, while the fringe corresponds to a set of mechanisms in the frontal and medial temporal lobes that control the contents of this global buffer. A consequence of this account is that there might be conscious imagistic representations that are not part of the nucleus. I argue that phenomenology can be linked to psychology and neuroscience and a meaningful way that illuminates both. (shrink)

Faced with the immensity of space, do astronomers regard us humans as insignificant specks in the vast cosmos? Do evolutionary biologists consider themselves to be mere animals? Do neuroscientists anticipate that one day the dissection of the brain will explain away our minds? Do experts on Artificial Intelligence see themselves as nothing but a form of robot? In Science and Wonders Russell Stannard asks the ultimate questions of a host of leading scientists and theologians in Britain and America. (...) He talks to the Archbishop of York in his Palace, to the psychiatrist Montague Barker on Freud's couch in Hampstead, to the biologist Steven Rose in his lab. How should we view ourselves in the light of modern science? Did the Big Bang mark the creation of the Universe, and if so does it imply or rule out a Creator? And how might human beings continue to evolve? (shrink)

We propose that Mealey's model is limited in its description of sociopathy because it does not provide an adequate role for the main organ mediating genes and behavior, namely, the brain. Further, on the basis of our research, we question the view of sociopaths as a homogeneous group.

The medical specialty of psychiatry should possess a basic science in which pathologies are considered deviations from normal brain physiology. Historically, psychoanalytic pathogenesis was considered separately from brain physiology. It was not scientific because observations could not be refuted. Countering this, Eli Robins's legacy stemmed partly from his having been damaged by a psychoanalyst. It eschewed pathogenesis. Attempting to integrate psychiatry with medicine more generally, Robins and colleagues refocused on empiricism, although they acknowledged the brain's centrality. Here (...) I hold that the term biology used in the context of psychiatry should broadly encompass social facets of organismal function. The term sociophysiology may best describe the central basic science of psychiatry because it alludes to brain functions used for the person's social realm. Disruptions of such functions result in deviant behaviors and unpleasant feelings which psychiatrists diagnose and treat. Future study encompassing top-down and bottom-up research should include genome-neural-behavioral analyses. (shrink)

I selectively and critically review the state of knowledge about human evolution and the place of humans vis-à-vis living apes, with emphasis on bipedal posture and locomotion, expansion of the brain and associated cognitive capacities, speech, tool behavior, culture, and society. I end with a personal perspective on God and Heaven.

Carruthers views unsymbolized thinking as and, therefore, as a potential threat to his mindreading-is-prior position. I argue that unsymbolized thinking may involve (non-symbolic) sensory aspects; it is therefore not purely propositional, and therefore poses no threat to mindreading-is-prior. Furthermore, Descriptive Experience Sampling lends empirical support to the view that access to our own propositional attitudes is interpretative, not introspective.

In this book, the authors present current research in the study of the philosophy of the mind. Topics discussed in this compilation include the concepts of hope and belief; how consciousness builds the subject through relating and human behaviour; analysing the neurophysiological mechanism of qigong on the mind and brain activity; the conscious and unconscious mind and implications for society, religion, and disease; how the mind is shaped by culture; and the power of computational mathematics to explore some of (...) the universal ways by which each human mind builds its image of the world.

It is largely acknowledged that natural languages emerge not just from human brains but also from rich communities of interacting human brains (Senghas, ). Yet the precise role of such communities and such interaction in the emergence of core properties of language has largely gone uninvestigated in naturally emerging systems, leaving the few existing computational investigations of this issue at an artificial setting. Here, we take a step toward investigating the precise role of community structure in the emergence of linguistic (...) conventions with both naturalistic empirical data and computational modeling. We first show conventionalization of lexicons in two different classes of naturally emerging signed systems: (a) protolinguistic “homesigns” invented by linguistically isolated Deaf individuals, and (b) a natural sign language emerging in a recently formed rich Deaf community. We find that the latter conventionalized faster than the former. Second, we model conventionalization as a population of interacting individuals who adjust their probability of sign use in response to other individuals' actual sign use, following an independently motivated model of language learning (Yang, , ). Simulations suggest that a richer social network, like that of natural (signed) languages, conventionalizes faster than a sparser social network, like that of homesign systems. We discuss our behavioral and computational results in light of other work on language emergence, and other work of behavior on complex networks. (shrink)

Steven Pinker has said that one of the most important questions humans can ask of themselves is whether moral progress has occurred or is likely to occur. Buchanan and Powell here address that question, in order to provide the first naturalistic, empirically-informed and analytically sophisticated theory of moral progress--explaining the capacities in the human brain that allow for it, the role of the environment, and how contingent and fragile moral progress can be.

The link between parasite-stress and complex psychological dispositions implies that the social, political, and economic benefits likely to flow from public health interventions that reduce rates of non-zoonotic infectious disease are far greater than have traditionally been thought. We sketch a prudential and ethical argument for increasing public health resources globally and redistributing these to focus on the alleviation of parasite-stress in human populations.
