Theories of spatial cognition are derived from many sources. Psychologists are concerned with determining the features of the mind which, in combination with external inputs, produce our spatialized experience. A review of philosophical and other approaches has convinced us that the brain must come equipped to impose a three-dimensional Euclidean framework on experience – our analysis suggests that object re-identification may require such a framework. We identify this absolute, nonegocentric, spatial framework with a specific neural system centered in the hippocampus.A (...) consideration of the kinds of behaviours in which such a spatial mapping system would be important is followed by an analysis of the anatomy and physiology of this system, with special emphasis on the place-coded neurons recorded in the hippocampus of freely moving rats. A tentative physiological model for the hippocampal cognitive map is proposed. A review of lesion studies, in tasks as diverse as discrimination learning, avoidance, and extinction, shows that the cognitive map notion can adequately explain much of the data.The model is extended to humans by the assumption that spatial maps are built in one hemisphere, semantic maps in the other. The latter provide a semantic deep structure within which discourse comprehension and production can be achieved. Evidence from the study of amnesic patients, briefly reviewed, is consistent with this extension. (shrink)
[John Dupré] This paper attacks some prominent contemporary attempts to provide reductive accounts of ever wider areas of human behaviour. In particular, I shall address the claims of sociobiology to provide a universal account of human nature, and attempts to subsume ever wider domains of behaviour within the scope of economics. I shall also consider some recent suggestions as to how these approaches might be integrated. Having rejected the imperialistic ambitions of these approaches, I shall briefly advocate a more pluralistic (...) approach to the understanding of human behaviour, and one which leaves some space for the possibility of genuine human autonomy. /// [John O'Neill] One response to Dupré's criticism of rational choice theory's unifying aspirations is that it is aimed at over-ambitious versions of the theory. Immodesty about the scope of rational choice theory may look more plausible given suitable modesty in assumptions about the rational agent. The paper examines problems with one immodest version of the theory-public choice theory-and show how these shed light on problems in modest versions employing minimal assumptions about the preference structure of rational agents. However, while rational choice theory may fail in its unifying ambitions, I argue those aspirations are defensible. (shrink)

The Lancet–O’Neill Institute/Georgetown University Commission on Global Health and Law published its report on the Legal Determinants of Health in 2019. The term ‘legal determinants of health’ draws attention to the power of law to influence upstream social and economic influences on population health. In this article, we introduce the Commission, including its background and rationale, set out its methodology, summarize its key findings and recommendations and reflect on its impact since publication. We also look to the future, making suggestions (...) as to how the global health community can make the best use of the Commission’s momentum in relation to using law and legal tools to advance population health.

It is common to regard love, friendship, and other associational ties to others as an important part of a happy or flourishing life. This would be easy enough to understand if we focused on friendships based on pleasure, or associations, such as business partnerships, predicated on mutual advantage. For then we could understand in a straightforward way how these interpersonal relationships would be valuable for someone involved in such relationships just insofar as they caused her pleasure or causally promoted her (...) own independent interests. But many who regard love, friendship, and other associational ties as an important part of a happy or flourishing life suppose that in many sorts of associations—especially intimate associations—the proper attitude among associates is concern for the other for the other's own sake, not just for the pleasure or benefits one can extract from one's associates. It is fairly clear how having friends of this sort is beneficial. What is less clear is how being a friend of this sort might contribute to one's own happiness or well-being. Even if we can explain this, it looks as if the contribution that friendship makes to one's happiness could not be the reason one has to care for friends, for that would seem to make one's concern for others instrumental, not a concern for the other for her own sake.

Brian O'Shaughnessy puts forward a bold and original theory of consciousness, one of the most fascinating but puzzling aspects of human existence. He analyses consciousness into purely psychological constituents, according pre-eminence to its epistemological power; the result is an integrated picture of the conscious mind in its natural physical setting. Consciousness and the World is a rich and exciting book, a major contribution to our understanding of the mind.
Many current neurophysiological, psychophysical, and psychological approaches to vision rest on the idea that when we see, the brain produces an internal representation of the world. The activation of this internal representation is assumed to give rise to the experience of seeing. The problem with this kind of approach is that it leaves unexplained how the existence of such a detailed internal representation might produce visual consciousness. An alternative proposal is made here. We propose that seeing is a way of (...) acting. It is a particular way of exploring the environment. Activity in internal representations does not generate the experience of seeing. The out- side world serves as its own, external, representation. The experience of seeing occurs when the organism masters what we call the gov- erning laws of sensorimotor contingency. The advantage of this approach is that it provides a natural and principled way of accounting for visual consciousness, and for the differences in the perceived quality of sensory experience in the different sensory modalities. Sev- eral lines of empirical evidence are brought forward in support of the theory, in particular: evidence from experiments in sensorimotor adaptation, visual “filling in,” visual stability despite eye movements, change blindness, sensory substitution, and color perception.

What role, if any, should our moral intuitions play in moral epistemology? We make, or are prepared to make, moral judgments about a variety of actual and hypothetical situations. Some of these moral judgments are more informed, reflective, and stable than others ; some we make more confidently than others; and some, though not all, are judgments about which there is substantial consensus. What bearing do our moral judgments have on philosophical ethics and the search for first principles in ethics? (...) Should these judgments constrain, or be constrained by, philosophical theorizing about morality? On the one hand, we might expect first principles to conform to our moral intuitions or at least to our considered moral judgments. After all, we begin the reflection that may lead to first principles from particular moral convictions. And some of our moral intuitions are more fixed and compelling than any putative first principle. If so, we might expect common moral beliefs to have an important evidential role in the construction and assessment of first principles. On the other hand, common moral beliefs often rest on poor information, reflect bias, or are otherwise mistaken. We often appeal to moral principles to justify our particular moral convictions or to resolve our disagreements. Insofar as this is true, we may expect first principles to provide a foundation on the basis of which to test common moral beliefs and, where necessary, form new moral convictions. (shrink)
