Yet debates between emergentist and reductionist accounts of specifi c phenomena, and of visions of the natural world generally, continue to be hampered by imprecision or outright ambiguity in the use of terms. The term ‘emergence’ is clearly evocative for thinkers across the spectrum of those who theorize about the relationship between ‘high-level’ theories, and the real-world properties and dynamics they seek to describe, and theories and phenomena that pertain to more basic physical systems. Evocative, but extremely vague. Emergent phenomena are said to arise out of and be sustained by more basic phenomena, while at the same time exerting a ‘top-down’ control, constraint or some other sort of infl uence upon those very sustaining processes. To some critics, this has the air of magic, as it seems to suggest a kind of circular causality. (See Kim, 1999, for an argument to this conclusion.) Other critics deem the concept of emergence to be objectionably anti-naturalistic, requiring the onset at particular historical junctures of novel properties and behavior that are discontinuous with the world’s fundamental dynamics. Objections such as these have led many thinkers to construe emergent phenomena as complementary to yet harmonious with the behavior of fundamental physical entities supposed to be uniform in every context, including those involving emergent phenomena. On this view, emergent properties and the patterns to which they give rise are explanatorily self- contained. They are embedded in nature at a relatively coarse-grained level of structure while not ‘disrupting’ or ‘violating’ the ordinary dynamics of the fi ner-grained (more fundamental) levels. Nature, on this understanding, has a hierarchical structure, with each level of the hierarchy (corresponding to basic physics, chemistry, various levels of biology, and psychology and other information-based sciences) requiring its own concepts and laws to capture the distinctive behavior it exhibits. However, the preceding attempt at reconciling emergence with a (pre- sumed) pervasive causal continuity at the fundamental level can seem to defl ate emergence of its initially profound signifi cance. It locates the xii Introduction ‘autonomy’ of higher-level sciences in their capacity to describe coarse- grained patterns in the world’s mosaic that, however interesting and useful, do not contribute to driving the world’s evolution. The true causal work, on this objection, is all done at the level of basic physics. On refl ection, higher-level sciences appear as mere shorthand in the business of describing the world’s behavior. As it is often put, such an outlook threatens to turn emergence into an epistemological, rather than metaphysical, concept. (See O’Connor & Wong, 2006.) Proposals and criticisms such as those just gestured at constitute, in skel- etal form, the basic problematic informing modern discussion of the concept of emergence. It is mirrored by similar controversy over how best to characterize the opposite systematizing impulse, usually given the equally evocative but vague term, “reductionism.” We have collected the chapters in this volume in the belief that much progress has been made in recent years in clarifying the alternatives and the proper terms in which compet- ing claims of evidential support should be advanced. While it is scarcely credible for a partisan to claim that his or her favored view has been more or less established, inadequacies in some older formulations and arguments have been exposed, narrowing the fi eld a bit. The new essays collected here refl ect that improved perspective and attempt to advance the debate along one or another front. The volume has three parts. We provide a detailed introduction to each part immediately prior to the chapters in that part. Here, we make but short and general remarks. Part I lays a general ontological foundation. In it, six authors consider different accounts of how we might develop an emergentist picture of nature. Most target avowedly metaphysical (and not merely epistemological) construals of emergence. Collectively, they advance a number of fresh proposals, while being informed by philosophical and scientifi c discussion to date. Through these chapters, the reader will get a pretty thorough understanding of the range of highly general alternatives that have been fl oated in recent discussion. In Part II, the authors focus specifi cally on views concerning the status of mind in the physical world.
