The key idea behind reduction is a simple and familiar one: it’s that there’s more to things than meets the eye. Surprisingly, this simple idea provides the resources to block a number of notable anti-reductionist arguments: Mackie’s argument from queerness against objective moral values, Kripke’s Humphrey objection and its recent variants, and Jubien’s objection from irrelevance against Lewisian modal realism. What is wrong with each of these arguments is that they suppose that what is to be reduced must not (...) be dissimilar to what it is to be reduced to. This supposition is shown to be misguided and that the success or otherwise of a reduction turns on quite different considerations. (shrink)

The emergence of cave art in Europe about 30,000 years ago is widely believed to be evidence that by this time human beings had developed sophisticated capacities for symbolization and communication. However, comparison of the cave art with the drawings made by a young autistic girl, Nadia, reveals surprising similarities in content and style. Nadia, despite her graphic skills, was mentally defective and had virtually no language. I argue in the light of this comparison that the existence of the cave (...) art cannot be the proof which it is usually assumed to be that the humans of the Upper Palaeolithic had essentially ‘modern’ minds. The article includes peer commentary by Paul Bahn, Paul Bloom, Uta Frith, Ezra Zubrow, Steven Mithen, Ian Tattersall, Chris Knight, Chris McManus and Daniel Dennett , with response by Nicholas Humphrey.

This book is a tour-de-force on how human consciousness may have evolved. From the "phantom pain" experienced by people who have lost their limbs to the uncanny faculty of "blindsight," Humphrey argues that raw sensations are central to all conscious states and that consciousness must have evolved, just like all other mental faculties, over time from our ancestorsodily responses to pain and pleasure. '.

Essays discuss the evolution of consciousness, self-knowledge, aesthetics, religious ecstasy, ghosts, and dreams.

How is consciousness possible? What biological purpose does it serve? And why do we value it so highly? In Soul Dust, the psychologist Nicholas Humphrey, a leading figure in consciousness research, proposes a startling new theory. Consciousness, he argues, is nothing less than a magical-mystery show that we stage for ourselves inside our own heads. This self-made show lights up the world for us and makes us feel special and transcendent. Thus consciousness paves the way for spirituality, and allows (...) us, as human beings, to reap the rewards, and anxieties, of living in what Humphrey calls the "soul niche." Tightly argued, intellectually gripping, and a joy to read, Soul Dust provides answers to the deepest questions. It shows how the problem of consciousness merges with questions that obsess us all--how life should be lived and the fear of death. Resting firmly on neuroscience and evolutionary theory, and drawing a wealth of insights from philosophy and literature, Soul Dust is an uncompromising yet life-affirming work--one that never loses sight of the majesty and wonder of consciousness.

The mind-body problem is widely seen as the great remaining challenge to science and philosophy. Why and how did matter evolve to take on the quality of mind? The author takes the reader to the edges of current knowledge and back to the beginning of time, before mind existed, and in doing so constructs a history of consciousness.

This is a 5 page summary with three diagrams of the main objectives and some work in progress at the University of Birmingham Cognition and Affect project. involving: Professor Glyn Humphreys (School of Psychology), and Luc Beaudoin, Chris Paterson, Tim Read, Edmund Shing, Ian Wright, Ahmed El-Shafei, and (from October 1994) Chris Complin (research students). The project is concerned with "global" design requirements for coping simultaneously with coexisting but possibly unrelated goals, desires, preferences, intentions, and other kinds of (...) motivators, all at different stages of processing. Our work builds on and extends seminal ideas of H.A.Simon (1967). We are exploring "broad and shallow" architectures combining varied capabilities most of which are not implemented in great depth. The poster summarises some ideas about management and meta-management processes, attention filtering, and the relevance to emotional states involved "perturbances", where there is partial loss of control of attention.

The purpose of this book is to build towards an explanation of just what the matter is.

Nicholas Humphrey's writings about the evolution of the mind have done much to set the agenda for contemporary psychology.

This paper develops an inventory and conceptual map of espoused organizational values. We suggest that espoused values are fundamentally different to other value forms as they are collective value statements that need to coexist as a basis for organizational activity and performance. The inventory is built from an analysis of 3112 value items espoused by 554 organizations in the UK and USA in both profit and not-for-profit sectors. We distil these value items into 85 espoused value labels, and these are (...) assessed in terms of their similarity and difference through judgements made by 53 experienced individuals. The resulting conceptual map facilitates the evaluation of values which are espoused at the organizational level, as opposed to aggregations of personal values, an important distinction that is often ignored in the literature. This analysis identifies a number of distinct areas of emphasis occupied by espoused values. In particular, the richness of value labels that relates to broader ethical issues may be aimed at external stakeholder management, but also may have an increasing influence on organizational behaviour as they are embedded into organizational practices. By advancing our understanding of espoused values, through an analysis of those being used in practice, we provide a means by which future research into organizational values and ethical issues can progress.

The identity of conscious states and brain states must remain a mystery until we find a way of characterising both sides of the equation in terms that have the same ‘dimensions’. In this paper I stress the need for ‘dual currency concepts’ that not only are but can be seen to be as appropriate for talking about, say, the experience of pain as for talking about the corresponding working of the brain. In the light of evolutionary theory I make a (...) radically new proposal for what the common dimension is, centred on the idea of ‘authorship’. (shrink)

Sensations represent our subjective 'take' on sensory stimulation — how we feel about red light falling on the retina, salt dissolving on the tongue, a thorn piercing the skin. They tell — in the language of phenomenal properties -- what the experience is like for us. In so far as they represent the reality of this subjective relationship, they cannot be said to be illusory. The relationship, magical as it may seem, is not being misrepresented as something it is not. (...) If anything, it is being represented as something 'super-real'. (shrink)

Abstract. A rhesus monkey, Helen, from whom the striate cortex was almost totally removed, was studied intensively over a period of 8 years. During this time she regained an effective, though limited, degree of visually guided behaviour. The evidence suggests that while Helen suffered a permanent loss of `focal vision she retained (initially unexpressed) the capacity for `ambient vision.

The theory presented here is a near neighbour of Humphrey's theory of sensations as actions. O'Regan & Noë have opened up remarkable new possibilities. But they have missed a trick by not making more of the distinction between sensation and perception; and some of their particular proposals for how we use our eyes to represent visual properties are not only implausible but would, if true, isolate vision from other sensory modalities and do little to explain the phenomenology of conscious (...) experience in general.

We provide a comprehensive analysis of differences between socially responsible investment and conventional funds in terms of manager characteristics, performance and fund styles. We use holdings-based analysis to evaluate fund performance and style, which allows us to perform a more in-depth analysis than the extant literature. We find that SRI managers have longer tenure and are more likely to be a female. However, these differences do not result in any significant difference in the performance of SRI and conventional funds. Further, (...) it is possible to find an SRI fund of any style, although these funds are under-represented in value styles. (shrink)

It is the ambition of evolutionary psychology to explain how the basic features of human mental life came to be selected because of their contribution to biological survival. Counted among the most basic must be the subjective qualities of conscious sensory experience: the felt redness we experience on looking at a ripe tomato, the felt saltiness on tasting an anchovy, the felt pain on being pricked by a thorn. But, as many theorists acknowledge, with these qualia, the ambition of evolutionary (...) psychology may have met its match. Everyone agrees that a trait can only contribute to an organism's biological survival in so far as it operates in the public domain. Yet almost everyone also agrees that the subjective quality of sensory experience is (at least for all practical purposes) private and without external influence. Then, maybe we must either concede that the subjective quality of sensations cannot after all have been determined by selection (even if this is theoretically depressing) or else demonstrate that the quality of sensations is not as private as it seems to be (even if this is intuitively unconvincing). No. I believe neither of these solutions to the puzzle is in fact the right one. I argue instead that the truth is that the quality of sensations has indeed been shaped by selection in the past, despite the fact that it is today effectively private. And this situation has come about as a result of a remarkable evolutionary progression, whereby the primitive activity of sensing slowly became "privatized" - that is to say, removed from the domain of overt public behavior and transformed into a mental activity that is now, in humans, largely if not exclusively internal to the subject's mind.

Prior literature on socially responsible investment has contended that excluding “sin stocks” from a portfolio will reduce performance and increase risk. Further, incorporating stocks of firms with positive social responsibility scores will improve performance and reduce risk. We simulate portfolios designed to mimic typical equity mutual funds’ holdings and investigate these propositions. We remove the potentially confounding influences of differences in manager skill, transaction costs and fees, and conduct a clean experiment on the effect of positive and negative portfolio screening. (...) We find no difference in the return or risk of screened and unscreened portfolios. We conclude that a typical socially responsible fund will neither gain nor lose from screening its portfolio.

This paper reports an experiment which investigates a possible cognitive antecedent of event-splitting effects (ESEs) experimentally observed by Starmer and Sugden (1993) and Humphrey (1995) – the learning of absolute frequency of event category impacting on the learning of probability of event category – and reveals some evidence that it is responsible for observed ESEs. It is also suggested and empirically substantiated that stripped-down prospect theory will accurately predict ESEs in some decision making tasks, but will not perform well (...) in others. This contention, it is argued, is indicative of fundamental descriptive shortcomings in the economic conception of choice under uncertainty and may entail implications beyond the direct concerns of this paper.

I said that the cure itself is a certain leaf, but in addition to the drug there is a certain charm, which if someone chants when he makes use of it, the medicine altogether restores him to health, but without the charm there is no profit from the leaf.

Mankind as a species has little reason to boast about his sensory capacities. A dog's sense of smell, a bat's hearing, a hawk's visual acuity are all superior to our own. But in one respect we may justifiably be vain: our ability to see colours is a match for any other animal. In this respect we have in fact surprisingly few rivals. Among mammals only our nearest relatives, the monkeys and apes, share our ability – all others are nearly or (...) completely colour-blind. In the animal kingdom as a whole colour vision occurs only in some fishes, reptiles, insects and birds. (shrink)

Problem reports result from several misunderstandings about the nature and functions of phenomenal consciousness. I discuss some philosophical and scientific correctives that, taken together, can make the hard problem seem less hard.

An accessible overview of Humphrey's evolving views on consciousness -- particularly the topic of phenomenal consciousness -- from his early neurophysiology studies in the 1960's to his debates with philosophers today.

The McCollough effect, an orientation-contingent color aftereffect, has been known for over 30 years and, like other aftereffects, has been taken as a means of probing the brain's operations psychophysically. In this paper, we review psychophysical, neuropsychological, and neuroimaging studies of the McCollough effect. Much of the evidence suggests that the McCollough effect depends on neural mechanisms that are located early in the cortical visual pathways, probably in V1. We also review evidence showing that the aftereffect can be induced without (...) conscious perception of the induction patterns. Based on these two lines of evidence, it is argued that our conscious visual experience of the world arises in the cortical visual system beyond V1. (shrink)

Reflexive consciousness evolved in the context of early human social life, as a means by which 'natural psychologists' could develop working models of their own and others' minds.

This paper examines Honig’s use of Rancière in her book ‘Democracy and the Foreigner’. In seeking to clarify the benefits of ‘foreignness’ for democratic politics it raises the concern that Honig does not acknowledge the ways in which her own democratic cosmopolitanism may be more akin to Rancière’s police than politics. By challenging Honig’s assertion that democracy is usually read as a romance with the suggestion that it is more commonly read as a horror, I unpick the interstices of Honig’s (...) and Rancière’s work to separate foreignness from democratic cosmopolitanism. Instead, although I posit democratic cosmopolitanism’s potential as a police more conducive to politics I also suggest that the particular salience of Honig’s ‘foreigner’ figure is that it supplements Rancièrian politics, demonstrating a praxis of ‘looking anew’ at our ordinary social practices. By making these seem strange to us, we can discover a new critical perspective from which to question and subvert, thereby furthering the potential of Rancièrian democratic politics. (shrink)

When people are unwell, they will often begin to recover just as soon as they receive medical attention., but before the treatment could have any direct effect and even when the treatment is a sham. Mere belief that recovery is coming can by itself bring the recovery about.

The sensation of red light falling on your eyes has something in common with the experience of looking at a cartoon in the New Yorker. The phenomenal quality of the sensation and the funniness of the joke are both properties of your subjective take on an external event and both arise in two steps. With sensations, your brain responds to signals from bodily sense organs with an internalized evaluative response; your mind reads this response and represents what it's like as (...) the subjective property of redness. With jokes, the cartoonist creates a clever drawing; your mind takes in the drawing and represents what it's like as the subjective property of funniness. This analogy -- deliberately deflationary -- helps elucidate the nature of phenomenal consciousness and its neural correlates, and exposes the 'hard problem' as a conceptual error. (shrink)

Block's notion of P-consciousness catches too much in its net. He would do better to exclude all states that do not have a sensory component. I question what he says about my work with the “blind” monkey, Helen.

Dreaming can provide a marvelous opportunity for the “playful” exploration of dramatic events. But the chance to learn to deal with danger is only a small part of it. More important is the chance to discover what it is like to be the subject of strange but humanly significant mental states. [Revonsuo].
