This paper explores the fundamental ideas that have motivated the idea of emergence and the movement of emergentism. The concept of reduction, which lies at the heart of the emergence idea is explicated, and it is shown how the thesis that emergent properties are irreducible gives a unified account of emergence. The paper goes on to discuss two fundamental unresolved issues for emergentism. The first is that of giving a “positive” characterization of emergence; the second is to give a coherent (...) explanation of how “downward” causation, a central component of emergentism, is able to avoid the problem of overdetermination.

An innocent form of emergence—what I call "weak emergence"—is now a commonplace in a thriving interdisciplinary nexus of scientific activity—sometimes called the "sciences of complexity"—that include connectionist modelling, non-linear dynamics (popularly known as "chaos" theory), and artificial life.1 After defining it, illustrating it in two contexts, and reviewing the available evidence, I conclude that the scientific and philosophical prospects for weak emergence are bright.

This paper is an attempt to understand the content of, and motivation for, a popular form of physicalism, which I call ‘non-reductive physicalism’. Non-reductive physicalism claims although the mind is physical (in some sense), mental properties are nonetheless not identical to (or reducible to) physical properties. This suggests that mental properties are, in earlier terminology, ‘emergent properties’ of physical entities. Yet many non-reductive physicalists have denied this. In what follows, I examine their denial, and I argue that on a plausible (...) understanding of what ‘emergent’ means, the denial is indefensible: non-reductive physicalism is committed to mental properties being emergent properties. It follows that the problems for emergentism—especially the problems of mental causation—are also problems for non-reductive physicalism, and they are problems for the same reason. (shrink)

This dissertation considers the history and philosophy of emergent evolution, and in particular the attempt to answer the question of the role of qualitative novelty in the evolutionary process. Chapter one examines the background to the theory of emergent evolution in the work of Charles Darwin. It is argued that Darwin's theory is neither tautologous nor revolutionary, and the application of Thomas Kuhn's theory of scientific revolution to the case of Darwinian evolution is criticized. Chapter two analyzes the work of (...) the comparative psychologist Conwy Lloyd Morgan, and his views on qualitative novelty are compared with those of other major contemporaneous emergentist theorists: Samuel Alexander, C. D. Broad and Roy Wood Sellars. Chapter three discusses the history of emergent evolution as a philosophical trend, up to and including the emergent materialism of Mario Bunge. An alternative emergentist view of the level structure of reality based on the four levels of matter, life, society and mind is proposed in the conclusion. (shrink)

Most readers will agree with the starting assumptions of Klee that contemporary science and philosophy assume a primarily micro-deterministic view of nature–and that this has long been the case, or was at least until the 1970s. Defending a strict micro-determinism, Klee argues that concepts of emergence that seemingly are opposed to micro-determinist doctrine can be shown, on analysis, to be ultimately consistent with a thoroughgoing philosophy of micro-determinism. An exception is made, however, in the case of my own view, labeled (...) “direct macro-determinism,” which he describes as “ultimately more troublesome” but then disposes of as being based on “simplistic analogies” and “metaphors” and “too weak to be conclusive.”.

Our aim in this paper is to bring to light the importance of the notion of économie animale in Montpellier vitalism, as a hybrid concept which brings together the structural and functional dimensions of the living body – dimensions which hitherto had primarily been studied according to a mechanistic model, or were discussed within the framework of Stahlian animism. The celebrated image of the bee-swarm expresses this structural-functional understanding of living bodies quite well: “One sees them press against each other, (...) mutually supporting each other, forming a kind of whole, in which each living part, in its own way, by means of the correspondence and directions of its motions, enables this kind of life to be sustained in the body” (Encyclopédie, article “Observation,” by Ménuret de Chambaud). What is important here is that every component part is always a living part, i.e., every structural unit is always functional. Interestingly, while the twin notions of ‘animal economy’ and organisation are presented as improvements over a mechanistic perspective, they are nonetheless compatible with an expanded sense of mechanism and by extension, with materialism as reflected notably in the writings of Ménuret and Bordeu. We thus propose both a revision and reconstruction of the historical status of the ‘animal economy’, and a reflection on its conceptual status. (shrink)

Dans cet article, nous nous proposons de mettre en évidence deux stratégies émergentistes possibles qui constituent une médiation intéressante entre les extrêmes classiques que sont le physicalisme réductionniste et le dualisme des substances. En distinguant trois niveaux de tension possibles entre monisme et dualisme — le niveau des substances, le niveau des propriétés causales et celui des prédicats — nous sommes amené à formuler deux positions philosophiques associées à deux concepts d’émergence distincts : l’émergence représentationnelle et l’émergence causale. Ces deux (...) concepts s’avèrent fidèles aux intuitions des premiers émergentistes véhiculées au travers de l’étymologie même du concept d’émergence, et permettent une interprétation non triviale de la maxime classique : « Le tout est plus que la somme des parties. »I emphasize in this paper two possible emergentist strategies that constitute interesting middle grounds between classical views that are reductive physicalism and substance dualism. By distinguishing three levels of tension between monism and dualism — the levels of substance, causal properties and predicates — one is allowed to formulate two philosophical views that may be associated with two distinct concepts of emergence : representational emergence and causal emergence. Both concepts are faithful to the intuitions of early emergentists that are conveyed in the very etymology of the concept of emergence, and they allow a non-trivial reading of the classical maxim : “the whole is more than the sum of the parts”.
