I argue that a dual-aspect theory of consciousness, associated with a particular class of quantum states, can provide a consistent account of consciousness. I illustrate this with the use of coherent states as this class. The proposal meets Chalmers 'requirements of allowing a structural correspondence between consciousness and its physical correlate. It provides a means for consciousness to have an effect on the world (it is not an epiphenomenon, and can thus be selected by evolution) in a way that supplements and completes conventional physics, rather than interfering with it. I draw on the work of Hameroff and Penrose to explain the consistency of this proposal with decoherence, while adding details to this work. The proposal is open to extensive further research at both theoretical and experimental levels.

The dominance in normal awareness of visual percepts, which are linked to space, obscures the fact that most thoughts are non-spatial. It is argued that the mind is intrinsically non-spatial, though in perception can become compresent with spatial things derived from outside the mind. The assumption that the brain is entirely spatial is also challenged, on the grounds that there is a perfectly good place for the non-spatial in physics. A quantum logic approach to physics, which takes non-locality as its starting point, offers a non-reductive way of reconciling the experience of mind with the world description of physics. For further progress it is necessary to place mind first as the key aspect of the universe.

Experiments are described, using electroencephalography (EEG) and simple tests of performance, which support the hypothesis that collapse of a quantum field is of importance to the functioning of the brain. The theoretical basis of our experiments is derived from Penrose (1989) who suggested that conscious decision-making is a manifestation of the outcome of quantum computation in the brain involving collapse of some relevant wave function. He also proposed that collapse of any wave function depends on a gravitational criterion. As different brain areas are known to subserve different functions, we argue that `Penrose collapse' must occur in a particular brain area when performing a task that uses it. Further, taking an EEG from the area should amplify the gravitational prerequisite for collapse, so affecting task performance. There are no non-quantum theories which could lead one to expect that taking an EEG could directly affect task performance by subjects. The results of both pilot and main experiments indicated that task performance was indeed influenced by taking an EEG from relevant brain areas. Control experiments suggested that the influence was quantum mechanical in origin, and was not due to any experimental artefact. The results are statistically significant and merit attempts at replication in an independent laboratory, preferably with more sophisticated equipment than was available to us.

This article arises from the remarkably multi-faceted book Brain and Being edited by Gordon Globus and others, hereafter referred to as B&B. It raises questions (though not unusually, few answers) about several related areas: the way in which quantum theory might endow the physical matter of the brain with surprising, though still essentially classical, properties; the possibility that quantum field theory might shed a wholly new light on aspects of consciousness, in both the subjective and neurological approaches; and, at the most speculative, the suggestion that the nature of being, as disclosed subjectively, can be understood in the light of one or other of the interpretations of quantum theory. I will consider these in turn.

Hay's Political Analysis raises foundational issues for all social scientists, not least in its outline for a via media, or middle way, between positivist and interpretivist social science. In this view, social science should be firmly grounded in empirical study but take seriously the notion that there is no privileged vantage point from which to generate dispassionate knowledge claims about the social world. This article asks whether this apparent via media is coherent and meaningfully captures what it means to be doing positivist and interpretivist social science without, so to speak, conceding too much ground to the other approach.

Receiving a diagnosis of cancer can be devastating. Cancer continues to be one of the most feared diagnoses, and experiencing pain is a major fear for people diagnosed with cancer. Cancer pain is complex in aetiology and can be acute or chronic and can be caused by various compression, ischaemic, neuropathic or inflammatory processes. Many people with cancer will experience excruciating pain, which is often underreported and undertreated. The reasons for this are complex and include various factors including fears and beliefs held by patients. Cognitive factors are important modulators of pain and the appraisals, meanings and beliefs that people have in relation to illness, cancer, and pain, have implications in regard to help-seeking behaviours and the coping strategies people adopt. Cancer pain can impact a range of psycho-social factors across its course. Cancer pain relates to higher rates of psychological distress, anxiety and low mood, and the perception of pain intensity is, in turn, influenced by psychological factors. Cancer pain can negatively affect psychological health, and psycho-social factors can affect the pain experience. It has been suggested that people with a life-limiting illness experience ‘total pain’, and this can encompass psychological, social, practical, spiritual domains. Research demonstrates that cancer is predominantly an illness affecting older people, yet there is a higher risk of under-treated pain in this age group and there is a paucity of research into the subjective experiences of older people managing their cancer pain. Many older people are required to self-manage cancer pain at home as outpatients, due to drivers to keep people out of inpatient care, such as the high healthcare costs of inpatient treatment, and patients wanting to manage their illness, and die, at home. Our own research into this area found that the self-management of cancer pain involves a sequential and temporal process, which centres on perceptions of control. We describe how the older people in our study experienced a perceived loss of control, followed by a sense of gaining control over pain through various experience of certain internal and external factors. The assessment and treatment of physical pain should be done in combination with assessment and treatment of psycho-social and spiritual pain, and interventions for cancer pain need to focus on increasing positive affect and reducing helplessness. No person should suffer with poorly controlled pain and we argue for the need for further research in this area to ensure adequate treatment for all.Clinical Implications: Assessment and treatment of physical pain in people with cancer needs to be conducted in combination with assessment and treatment of psycho-social issues and spiritual pain. Psychological and behavioural approaches have strong evidence supporting their efficacy for reducing cancer pain. Interventions should target helplessness and focus on increasing positive affect through positive psychological states including fighting spirit and resilience. Person-centred interventions that focus on helping people with the search for meaning may help those with cancer pain derive positive benefits.

Between 1965 and 2002 several key lines of research emerged which, taken together, can potentially revolutionise our understanding of the place of consciousness in the universe. Two of these are crucial: first, the analyses of human mental processes by Barnard, and independently by McGilchrist, revealing two separate elements, one rational and one based on relationships; and, second, research by several workers linking quantum theory to consciousness in much greater detail than hitherto. Both of these investigations use an alternative logical system in order to make sense of the quantum/consciousness area. In this book the author explains the close connections between these new ingredients – connections which until now have barely been noticed. Using these insights the author set out a new foundation for consciousness studies in which consciousness is integrated with physics while retaining its qualitatively different character. Finally the book discusses how this affects our everyday approach to ecology, religion, and spiritual practice.
