In this paper we intend to examine whether there are examples for emergence to be found in physics. The answer depends on the concept of emergence one invokes. We distinguish two such concepts, those of Broad and Kim. We will argue that it is unlikely that there will be examples with respect to the former because it runs counter to an explanatory strategy that is both well entrenched in physical practice and to a certain degree flexible. On the other hand (...) we will argue that all those physical systems that provide an example for supervenience are at the same time examples for emergence - at least if one defines emergence the way Kim does.

Convergent scientific realism entails that science will sooner or later arrive at the final theory of the fundamental constituents of matter. At that stage, all fundamental truths about nature will be discovered so that the search for basic principle seems bound to come to a halt. I explore options for a non-convergent scientific realism that allows for sustained progress in basic research. I defend the views that the coherence of non-convergent realism requires an emergence claim and that this claim can (...) be supported. I develop the example of the relation between equivalence classes among biological functions and their physiological realizations. Given strongly emergent laws in the sense elaborated in the paper, progress in basic research may survive the discovery of the laws governing the tinymost parts of matter. (shrink)

Nonreductive physicalism is currently one of the most widely held views about the world in general and about the status of the mental in particular. However, the view has recently faced a series of powerful criticisms from, among others, Jaegwon Kim. In several papers, Kim has argued that the nonreductivist's view of the mental is an unstable position, one harboring contradictions that push it either to reductivism or to eliminativism. The problems arise, Kim maintains, when we consider the causal powers (...) that mental properties are held to carry on the nonreductivist's view and the causal transactions into which mental events are said to enter. My aim here is less than that of defending nonreductive physicalism against all of Kim's criticisms. I wish primarily to call into question the claim that nonreductive physicalism is committed to emergentism with respect to the causal powers of the mental. As subsidiary points, I shall offer a limited defense of nonreductivism against two related objections that Kim raises. However, even if my conclusions are correct, problems remain for the nonreductivist's treatment of mental causation. I shall close the paper with a brief discussion of these difficulties. (shrink)

The tradition of pragmatism has, especially since Dewey, been characterized by a commitment to nonreductive naturalism. The notion of emergence, popular in the early decades of the twentieth century and currently re-emerging as a central concept in metaphysics and the philosophy of mind, may be useful in explicating that commitment. The present paper discusses the issue of the reality of emergent properties, drawing particular attention to a pragmatic way of approaching this issue. The reality of emergents can be defended as (...) a pragmatically-useful ontological commitment; hence, pragmatism can be employed as a tool in the debate over the structure and reality of emergence. This strategy of justifying ontological commitments is examined through historical and systematic discussions of the pragmatist tradition. It turns out, among other things, that while classical pragmatists did not specify any technical notion of emergence in the contemporary sense, their non-reductively naturalist views are relevant to the more recent emergence discussions -- especially because they rejected the metaphysical realism typical of today’s ontologically-oriented emergence theories.

We reconstruct genetic determinism as a reductionist thesis to the effect that the molecular properties of cells can be accounted for to a great extent by their genetic outfit. The non-reductionist arguments offered at this molecular level often use the relationship between structure and function as their point of departure. By contrast, we develop a non-reductionist argument that is confined to the structural characteristics of biomolecules; no appeal to functions is made. We raise two kinds of objections against the reducibility (...) claim underlying genetic determinism. First, some conceptual distinctions at the protein level cannot be captured on a genetic basis. A one-to-many relationship between DNA sequences and proteins emerges from them. Second, the relationship between genes and proteins is characterized by explanatory loops or reciprocal explanatory dependence. The presence of proteins is explained by the transcription from corresponding DNA sequences, and the latter is in turn accounted for by the action of proteins. By contrast, a reductive account requires a unidirectional explanatory dependence. (shrink)

There is a tension or even contradiction between mental causation - the belief that some mental events or properties are causally relevant for some physical events or properties - and the irreducibility of mental features to physical ones, the causal closure of the physical, and the assumption that there is no overdetermination of the physical. To reconcile these premises was a promise of nonreductive physicalism, but a closer inspection shows that it is, on the contrary, a source of the problem (...) - namely, the unintelligibility of mental causation. This has to do with the widely-held assumption that the mental supervenes on the physical. How can the mental be causally relevant, then? And what is the relationship of the mental and the physical? There are many options, including identity, realizationism, emergence, or some kind of reducibility. But they all have their own problems, e.g. they threaten mental reality, the causal closure of the physical, or scientific explanations. All these aspects are covered in Jaegwon Kim's book Mind in a Physical World. This paper is a detailed introduction to it, discussing and critically commenting it and those still intriguing, but also confusing and complicated issues of the mind-body problem, especially the ontology of mental causation.

The literature on physicalism often fails to elucidate, I think, what the word physical in physical ism precisely means. Philosophers speak at times of an ideal set of fundamental physical facts, or they stipulate that physical means non-mental , such that all fundamental physical facts are fundamental facts pertaining to the non-mental. In this article, I will probe physicalism in the very much tangible framework of quantum mechanics. Although this theory, unlike “ideal physics” or some “final theory of non-mentality”, is (...) an incomplete theory of the world, I believe this analysis will be of value, if for nothing else, at least for bringing some taste of physical reality, as it were, back to the debate. First, I will introduce a broad characterization of the physicalist credo. In Sect. 2, I will provide a rather quick review of quantum mechanics and some of its current interpretations. In Sect. 3, the notion of quantum non-separability will be analyzed, which will facilitate a discussion of the wave function ontology in Sect. 4. In Sects. 5 and 6, I will explore competing views on the implications of this ontology. In Sect. 7, I will argue that the prior results, based on a thoroughly realist interpretation of quantum mechanics, support only a weak version of non-reductive physicalism. (shrink)
