This engaging introduction to the fundamental issues of philosophy will prompt students to think actively about questions such as: Does God exist? Do we have souls? Does human life have meaning? Is there a real difference between right and wrong? and many others. The twelve chapters focus on these key philosophical questions and possible answers to them, and include readings by famous thinkers on each issue.

Two recent reports of mice homozygously deleted for cyclin D1 provide unequivocal evidence that the critical G1 cyclin, cyclin D1, is by itself rate‐limiting for growth in some mammalian tissues(1,2). Cyclin D1 knockout mice are small and exhibit behavioral abnormalities. Specific hypoplasias of retinal and mammary tissues suggest an unusual dependence on cyclin D1 function for tissue growth in those organs. The odd coincidences that cyclin D1 functions as the retinoblastoma gene kinase, together with associations between increased cyclin D1 expression (...) and breast cancer, suggest, but do not prove, a special function of cyclin D1 in those tissues.

As some see it, an impasse has been reached on the mind- body problem between mainstream physicalism and mainstream dualism. So lately another view has been gaining popularity, a view that might be called the 'Russellian theory of mind' (RTM) since it is inspired by some ideas once put forth by Bertrand Russell. Most versions of RTM are panpsychist, but there is at least one version that rejects panpsychism and styles itself as physicalism, and neutral monism is also a possibility. (...) In this paper I will attempt to sort out these different versions with a view to determining which, if any, have a chance of breaking the perceived impasse. The unsurprising conclusion will be that there are a lot of challenges ahead for the RTM theorist. The surprising conclusion will be that it's not clear that pan- psychist RTM holds an advantage over the other versions in this regard. (shrink)

Anyone who is a color eliminativist‐i.e., believes that the physical world is colorless‐must explain how our sense experience of color can be so systematically illusory. As it turns out, it is difficult to do this without committing oneself to dualism. In this paper I explore the options available to the color eliminativist in this regard, and argue that his/her prospects are more promising, though still far from certain, if s/he adopts the position that sense experience is strictly intentional.

Not so long ago, the idea that analytic philosophers would be taking panpsychism seriously would have been hard to believe. That is because in its early, logical positivist, stage, the analytic movement earned the reputation of being militantly anti-metaphysical. But analytic philosophy has come a long way since the heyday of logical positivism; and, in fact, the dialectic of recent debates on the mind–body problem among analytic philosophers has pushed many of them in the direction of panpsychism. In this paper, (...) I want to explain how this has come about and take a look at some of the versions of panpsychism that have emerged. This will involve running through a quick history of debates on the mind–body problem since about 1960, focusing on how panpsychism has been proposed as a promising, though not unproblematic, way of breaking an apparent impasse that has emerged between more standard physicalist and dualist theories of mind. Along the way, I will also have occasion to comment on the prospects of panpsychism as a respectable scientific theory and how a number of scientists stand on this. (shrink)

A popular defense of physicalist theories of consciousness against anti-physicalist arguments invokes the existence of ‘phenomenal concepts’. These are concepts that designate conscious experiences from a first person perspective, and hence differ from physicalistic concepts; but not in a way that precludes co-referentiality with them. On one version of this strategy phenomenal concepts are seen as (1) type demonstratives that have (2) no mode of presentation. However, 2 is possible without 1-call this the ‘bare recognitional concept’ view-and I will argue (...) that this avoids certain recent criticisms while retaining the virtue of finessing the ‘mode of presentation’ problem for phenomenal concepts. But construing phenomenal concepts this way seems to not do justice to the phenomenology of conscious experience. In this paper I examine whether or not this impression can be borne out by a good argument. As it turns out, it is harder to do so than one might think. It can be done, but it involves somewhat more convoluted reasoning than one might have supposed necessary. Having shown that, I will end with a few brief remarks on what my argument means for attempts to preserve a physicalist account of consciousness. (shrink)

We reflect, using a vignette, on conceptual tensions and the value judgements that lie behind difficult decisions about whether or not the older person with dementia should return home or move into long-term care following hospital admission. The paper seeks, first, to expose some of the difficulties arising from the assessment of residence capacity, particularly around the nature of evaluative judgements and conceptual tensions inherent in the legal approach to capacity. Secondly, we consider the assessment of best interests around place (...) of residence, which demonstrates significant conceptual tensions. In addition, ‘best interests’ raise issues around the perception of risk and the perceptions of the family and crucially involve the notions of autonomy and trust. Finally, we not only gesture at some practical considerations based on insights from values-based medicine, but also make the suggestion that we require tighter functional assessments of residence capacity coupled with broader judgements about best interests.

Frank Jackson formulated his knowledge argument as an argument for dualism. In this paper I show how the argument can be modified to also establish the irreducibility of the secondary qualities to the properties of physical theory, and ultimately "secondary quality eliminativism"- the view that the secondary qualities are physically uninstantiated.

Evans’ 1968 ANALOGY system was the first computer model of analogy. This paper demonstrates that the structure mapping model of analogy, when combined with high‐level visual processing and qualitative representations, can solve the same kinds of geometric analogy problems as were solved by ANALOGY. Importantly, the bulk of the computations are not particular to the model of this task but are general purpose: We use our existing sketch understanding system, CogSketch, to compute visual structure that is used by our existing (...) analogical matcher, Structure Mapping Engine (SME). We show how SME can be used to facilitate high‐level visual matching, proposing a role for structural alignment in mental rotation. We show how second‐order analogies over differences computed via analogies between pictures provide a more elegant model of the geometric analogy task. We compare our model against human data on a set of problems, showing that the model aligns well with both the answers chosen by people and the reaction times required to choose the answers.

BackgroundConcerns about decision making related to resuscitation have led to two important challenges in the courts resulting in new legal precedents for decision-making practice. Systematic research investigating the experiences of doctors involved in decisions about resuscitation in light of the recent changes in law remains lacking.AimTo analyse the practice of resuscitation decision making on hospital wards from the perspectives of doctors.DesignThe data presented in this paper were collected as part of a wider research study of end-of-life care in an acute (...) hospital setting. Data collection comprised ethnographic non-participant observation on two acute hospital wards and individual interviews with patients, relatives and healthcare professionals caring for patients thought to be approaching the end of life. Data were analysed using a constructivist grounded theory approach.ResultsDiscussions and decision making about resuscitation present many challenges for those involved on acute medical wards. The data highlight the potential for multiple interpretations of legal precedents, creating misunderstandings that may impact patient care in less positive ways.ConclusionsThis paper provides unique insights into how doctors respond to the changing medico-legal culture and the subsequent effects on patient care. It demonstrates how the juridification of medical practice can occur. It highlights the potential benefit of a structure to support clinicians, patients and relatives in discussing and navigating decisions around care at the end of life in line with the patient’s wishes and preferences. Recommendations for future research are made and legal ramifications are discussed. (shrink)

In a recent article, Grover Maxwell presents a case for a kind of mind-brain identity theory which he claims precludes materialism. His case is based on some views about meaning which I find plausible. However, I will argue that, by adopting certain assumptions about the nature of sensory experience, and extending some of Maxwell's views about meaning in a plausible way, the issue of a materialistic identity theory is reopened. Ultimately, I will agree that such a theory is not true, (...) but more is needed to show this than Maxwell gives us. But the question of materialism is not thereby closed, because it has become axiomatic these days that materialism does not require an identity theory. So I will go on to consider if all forms of materialism have been ruled out by Maxwell's theory, as extended by me. I will end with a tentative affirmative answer but also with a proposal which, if it can be worked out, would reverse the decision. (shrink)

The subjectivity of consciousness is widely regarded as a major stumbling block for materialist theories of mind. In this paper I show how Kripkean arguments against identity theories , and in particular a Kripkean argument against qualia-material property identity developed by Frank Jackson are a way of highlighting this problem. As such, Kripkean arguments are akin to recent discussions of subjectivity by Thomas Nagel and Frank Jackson . I then consider some recent attempts to refute Kripkean arguments or otherwise show (...) that subjectivity is not an insurmountable problem for identity theory. The most promising attempt is one that I myself develop, based on some ideas by Keith Gunderson . But I contend that even it, let alone any of the others, is not without problems. Thus, tentatively, Kripkean arguments against property identity succeed. (shrink)

A popular defense of physicalist theories of consciousness against anti-physicalist arguments is the “phenomenal concept strategy”. According to PCS there are phenomenal concepts that designate phenomenal properties, and whose use requires adopting the first person perspective with respect to those properties, thus allowing an epistemic gap between the phenomenal and the physical without requiring a metaphysical gap. One version of PCS is the quotational version, according to which phenomenal concepts are in part constituted by the very properties they designate. The (...) advertising for this version of PCS is that it does better justice to the phenomenology of consciousness than alternative versions. But in doing so, I argue, it threatens to reintroduce dualism. This can be avoided by adopting a Russellian account of physical concepts, but even with this we seem to be committed to a non-physicalist Russellian account of consciousness, and perhaps even a Russellian panpsychism. This can be avoided only by holding that, even though we now cannot see how the phenomenal supervenes on the physical, it does anyway, and perhaps future developments will make this clear. Thus, what starts out as a Type B physicalist strategy becomes a Type C strategy. (shrink)

Many philosophers have argued that dreams cannot be conscious states since they occur during sleep. Some wish to identify dreams with only what we remember of them and, discounting the reliability of memory, also discount dreams. I will argue that access to dreaming is not limited to our waking memories of them. Dreaming is similar to other marginal or altered states of consciousness, and as such can be held to involve consciousness even when we do not remember dreams.
