The mentalist mind-brain model is defended against alleged weaknesses. I argue that the perceived failings are based mostly on misinterpretation of mentalism and emergent interaction. Considering the paradigmatic concepts at issue and broad implications, I try to better clarify the misread mentalist view, adding more inclusive detail, relevant background, further analysis, and comparing its foundational concepts with those of the new cognitive paradigm in psychology. A changed "emergent interactionist" form of causation is posited that combines traditional microdeterminism with emergent "top-down" (...) control. This emergent form of causation has wide application to causal explanation in general and is hypothesized to be the key common precursor for the consciousness revolution and subsequent boom in new worldviews, "systems thinking," emerging new paradigms, and other transformative developments of the 1970s and 1980s.

Conceptual foundations for the changeover from behaviorism to mentalism are reviewed in an effort to better clarify frequently contested and misinterpreted features. The new mentalist tenets which I continue to support have been differently conceived to be a form of dualism, mind-brain identity theory, functionalism, nonreductive physical monism, dualist interactionism, emergent interactionism, and various other things. This diversity and contradiction are attributed to the fact that the new mentalist paradigm is a distinctly new position that fails to fit traditional philosophic (...) dichotomies. Formerly opposed features from previous polar alternatives become merged into a novel unifying synthesis, an unambiguous description of which demands redefinition of old terms or/and the invention of new terminology. The present analysis and interpretation are backed by statements from the early papers. (shrink)

Traditional scientific views of the conscious self and world we live in are challenged by an unprecedented outburst of emerging new paradigms, theories of consciousness, perceptions of reality, new sciences, new philosophies, epistemologies, and a host of other transformative approaches. This still expanding outburst can be traced, on both logical and chronologic grounds, not to chaos theory, ecology, the new physics, or dozens of other currently ascribed sources, but rather to the cognitive (consciousness) revolution that immediately preceded. These new approaches (...) all share one key feature in common, namely, they all depend, directly or indirectly, upon a refutation and successful overthrow of the long dominant materialist paradigm. This is what was required to shift consciousness from an acausal or "eliminable" status to a functionally indispensable role. Traditional "bottom‐up" micro‐determinism had to be supplemented by a reciprocal, "top‐down" control exerted by mental emergents over lower‐level components. This does not dispose of behaviorism or reductionism, as methodology, but simply incorporates these within a more comprehensive explanatory framework. With the long reign of materialist constraints finally broken, other antireductive views have proliferated but with little regard for what the new paradigm allows. (shrink)

. Prospects for uniting religion and science are brightened by recently changed views of consciousness and mind‐brain interaction. Mental, vital, and spiritual forces, long excluded and denounced by materialist philosophy, are reinstated in nonmystical form. A revised scientific cosmology emerges in which reductive materialist interpretations emphasizing causal control from below upward are replaced by revised concepts that emphasize the reciprocal control exerted by higher emergent forces from above downward. Scientific views of ourselves and the world and the kinds of values (...) upheld by scientific belief undergo basic transformations, making them more compatible with religious motivation and moral responsibility.

Roger W. Sperry received the Nobel Prize for Physiology in 1981 for his outstanding scientific achievements in connection with the study of people with severed brain commissures. Sperry linked the results of his research to philosophical considerations pertaining to the conscious mind of human beings and its place in the natural sciences. He was interested in the philosophical question of whether or not the severing of the cerebral hemispheres constituted a violation of the unity of consciousness. (...) class='Hi'>Sperry’s explanatory account of mind-body interaction forms part of a broadly construed theory of emergent interactionism – one that also purports to guarantee the unity of consciousness. In this article, I first present an intellectual profile of Sperry, outlining the evolution of his philosophical-scientific analyses. I then outline the emergence and flourishing of theories of emergence, along with the elements essentially associated with them. Using this as a basis, I go on to consider Sperry’s account of emergent interaction more closely, focusing on his understanding of downward causation. In conclusion, I show how his theory corresponds to a version of emergent interactionism, and seek to address some criticisms leveled against it. I also aim to establish how far this theory can be said to answer the question of the conscious character of mental states. (shrink)

For ages there has been a gap between the two cultures of the sciences and religions. According to Roger Sperry, science can now bridge the gap between the cold hard facts of the sciences and humanitarian and religious values. Sperry won the Nobel Prize in 1981 for his work on the differences between the left and right halves of the brain. For the past twenty years he has been campaigning for human consciousness and values to be investigated (...) scientificlly. This book describes Sperry's work and his struggle to guide humanity beyond a world divided. terms such as consciousness, value, love and joy are scientifically meaningful, just like terms referring to brain physiology, such as neural pathways and electrical impulse. The split between mind matter, or religion, and science can be removed, says Sperry, by expanding scientific research. Now, conscious experiences must be taken into account as scientific information about the brain. Our values, beliefs and goals can directly affect our brain states and physiology. (shrink)

In a recent Zygon article (June 1991), Roger Sperry argues for the unification of science and religion based on the principle of emergent causation within the central nervous system. After illustrating Sperry's position with some current experiments, I suggest that his conclusions exceed his argument and the findings of contemporary neuroscience and propose instead a pluralistic, rather than unified, approach to the relations between religion and science necessitated by the incompleteness inherent in any strictly neurological account of (...) human nature.

Weaknesses in Roger Sperry's "Defense of Mentalism" that appeared in the Spring issue of JMB are described. Sperry's clarification of his mentalist position still appears to lack a plausible mechanism of interaction. The wheel rolling down hill analogy is described as "a ghost in the subcircuitry." Neurological Positivism's energetic mechanism of brain-mind interaction is summarized. The relatioship of systems theory to reductionism is described briefly in terms of NP.

In this article I will attempt to refute the claim that the mind is a radically emergent feature of the brain. First, the inter-related concepts of emergence, reducibility and constraint are considered, particularly as these ideas relate to hierarchical biological systems. The implications of radical emergence theories of the mind such as the one posited by Roger Sperry, are explored. I then argue that the failure of Sperry's model is based on the notion that consciousness arises as (...) a radically emergent feature ‘at the top command’ of a non-nested neurological hierarchy. An alternative model, one that avoids the dualism inherent in radical emergence theories, is offered in which the brain is described as producing a nested hierarchy of meaning and purpose that has no ‘top’ or ‘summit’. Finally, I will argue there remains a non-reducible aspect of consciousness that does not depend upon radical emergence theory, but rather on the mutual irreducibility of the subjective and objective points of view. This irreducible aspect of consciousness can be understood as the non-mysterious result of brain evolution and normal neural functioning. (shrink)

In his bestselling work of popular science, Sir Roger Penrose takes us on a fascinating roller-coaster ride through the basic principles of physics, cosmology, mathematics, and philosophy to show that human thinking can never be emulated by a machine.

In Reasons and the Good Roger Crisp answers some of the oldest questions in moral philosophy. Fundamental to ethics, he claims, is the idea of ultimate reasons for action; and he argues controversially that these reasons do not depend on moral concepts. He investigates the nature of reasons themselves, and how we come to know them. He defends a hedonistic theory of well-being and an account of practical reason according to which we can give some, though not overriding, priority (...) to our own good over that of others.

Over 50 years have passed since Roger Sperry formulated a simple model of how visual space, as seen by the retina, can be projected onto the brain in a two‐dimensional, topographic map during development. Sperry posited a set of two orthogonal gradients in the retina that gives each cell a positional identity. He further suggested that these molecules could be used to match up with complementary gradients in the target field of the retinal projection, the tectum. While (...) some investigators hold that the existence of such molecules may not be necessary to establish retinotectal maps, recent work has identified several cell surface proteins whose distributions are of the type predicted by Sperry. An unexpected twist comes from culture assays demonstrating that inhibitory activities on tectal membranes can guide the growth of processes from retinal neurons. Moreover, the expression patterns of several enzymes and three transcription factors suggest that these proteins are candidates for regulatory agents in the determination of cell position in the retina. In addition, results from perturbation experiments support the candidacy of two of the enzymes, and a new mutant screen has uncovered several as yet unidentified genes that are required for establishment of the proper retinotectal map. A number of these results were presented at a recent meeting on neurospecificity held in Cargese, Corsica and sponsored by NATO and NSF. (shrink)

Argues that the only way to understand the Confucian vision of the consummate moral life is to take the tradition on its own terms.

This paper argues for two theses: that degrees of belief are context sensitive; that outright belief is belief to degree 1. The latter thesis is rejected quickly in most discussions of the relationship between credence and belief, but the former thesis undermines the usual reasons for doing so. Furthermore, identifying belief with credence 1 allows nice solutions to a number of problems for the most widely-held view of the relationship between credence and belief, the threshold view. I provide a sketch (...) of a formal framework on which both theses are true. This is a modified Bayesian framework; I argue that despite making credences context-sensitive, the framework lets Bayesians hold on to their signature explanatory successes. The sort of context-sensitivity claimed for credences here mirrors the sort of context-sensitivity I have elsewhere claimed for outright belief: one's credences depend, in part, on the space of alternative possibilities one takes seriously in a context.

What is music, what is its value, and what does it mean? In this stimulating volume, Roger Scruton offers a comprehensive account of the nature and significance of music from the perspective of modern philosophy. The study begins with the metaphysics of sound. Scruton distinguishes sound from tone; analyzes rhythm, melody, and harmony; and explores the various dimensions of musical organization and musical meaning. Taking on various fashionable theories in the philosophy and theory of music, he presents a compelling (...) case for the moral significance of music, its place in our culture, and the need for taste and discrimination in performing and listening to it. Laying down principles for musical analysis and criticism, this bold work concludes with a theory of culture--and a devastating demolition of modern popular music. "A provocative new study."--The Guardian. (shrink)

Roger Ariew presents a new account of Descartes as a philosopher who sought to engage his contemporaries and society. He argues that the Principles of Philosophy was written to rival Scholastic textbooks, and considers Descartes' enterprise in contrast to the tradition it was designed to replace and in relation to the works of the first Cartesians.

This paper argues for a treatment of belief as essentially sensitive to certain features of context. The first part gives an argument that we must take belief to be context-sensitive in the same way that assertion is, if we are to preserve appealing principles tying belief to sincere assertion. In particular, whether an agent counts as believing that p in a context depends on the space of alternative possibilities the agent is considering in that context. One and the same doxastic (...) state may amount to belief that p in one context but not another. The second part of the paper gives a formal treatment of doxastic states, according to which belief is context-sensitive along just these lines. The model is applied to characterize (but not to refute) skeptical arguments. (shrink)
