Interlevel Relations in Science

In recent years, several authors advocated neuroscience imperialism, an instance of scientific imperialism whereby neuroscience methods and findings are systematically applied to model and explain phenomena investigated by other disciplines. Calls for neuroscience imperialism target a wide range of disciplines, including psychology, economics, and philosophy. To date, however, neuroscience imperialism has not received detailed attention by philosophers, and the debate concerning its identification and normative assessment is relatively underdeveloped. In this paper, I aim to remedy this situation by making some (...) conceptual distinctions about neuroscience imperialism and by providing a normative assessment of prominent calls in its favour. I shall articulate and defend two interrelated claims that, I argue, undermine prominent calls for neuroscience imperialism. First, the proponents of neuroscience imperialism significantly overstate the evidential and explanatory relevance of neuroscience methods and findings for the disciplines they target. And second, prominent calls for neuroscience imperialism point to an untenable reductionist position, which rests on unsupported empirical and normative presuppositions. To substantiate these two claims, I shall draw on two sets of influential calls for neuroscience imperialism, which respectively target the economic modelling of choice and entrenched philosophical conceptions of free agency.

Critics of multiple realizability have recently argued that we should concentrate solely on actual here-and-now realizations that are found in nature. The possibility of alternative, but unactualized, realizations is regarded as uninteresting because it is taken to be a question of pure logic or an unverifiable scenario of science fiction. However, in the biological context only a contingent set of realizations is actualized. Drawing on recent work on the theory of neutral biological spaces, the paper shows that we can have (...) ways of assessing the modal dimension of multiple realizability that do not have to rely on mere conceivability.

The detailed analysis allows to discern seven kinds of integration, namely: I₁ consisting in the synthesis of scientific disciplines from their elements, including disciplinary unification I₁; I₂ inclusion of a science in (reduction to) another, more general; I₃ - links between different sciences, especially establishing of common elements; I₄ - interdisciplines bridging various sciences; I₅ - combination of two (or more) disciplines into a new (complex) science; I₆ - a general approach to several domains or multidisciplinary unification; I₇ - transdisciplinary (...) sciences about relations of the same type in various traditional domains. These kinds of integration are interwoven with processes of differentiation, viz. D₁ - internal differentiation of the sciences resulting of I₁; D₂ - interdisciplinary differentiation concomitant I₄, and D₃ - specialization of I₇ sciences in several sections. As a result integration and differentiation are combined in the pairs I₁ - D₁, I₇ - D₃, and D₂ - I₄. The processes of integration (and differentiation) may be presented schematically in the following (not strictly isolated one of another) sequence: in the 17th century started I₁ followed by D₁, and in the last decades by I₁'; during the 18th and the 19th c. cases of I₂ and I₃ appear; I₄ (together with D₂) is unfolding since the late 19th century. Finally, I₇ (and D₃), as well as I₅ and I₆ pertain to the latter half of our century. Representative are for one thing I₁, I₄, and I₇ outlining the main stages of integration and at the same time connected with respective kinds of differentiation. (shrink)

In the paper a theory of relevant properties is developed. The theory permits us to distinguish between properties that are relevant to an object and the properties that are irrelevant to it. Predication is meaningful only if a property is relevant to an object. On the base of introducing a special negative type of predication as opposed to usual sentential negation, a new notion of generalization for properties is defined. Context-free, as weIl as context-depended relevance of properties are considered.

A través de una serie de ejemplos matemáticos elementales se Ilega a proponer una definición bastante general de Indistinguibilidad, por medio de operadores con valores en semigrupos conmutativos ordenados. Tal definición se aplica a casos provenientes de diversos campos, muchos de los cuales exhiban la propiedad da rotura de las cadenas de objetos relacionados a causa de un cierto parecido.

David Sloan Wilson has recently revived the idea of a group mind as an application of group selectionist thinking to cognition. Central to my discussion of this idea is the distinction between the claim that groups have a psychology and what I call the social manifestation thesis-a thesis about the psychology of individuals. Contemporary work on this topic has confused these two theses. My discussion also points to research questions and issues that Wilson's work raises, as well as their connection (...) to externalist conceptions of the mind familiar since the work of Putnam and Burge.

Intuitivamente, la realidad está formada por entidades y hechos existentes y concretos. Sin embargo, nuestro lenguaje y pensamiento versa también sobre hechos meramente posibles, sobre cosas inexistentes y entidades abstractas. ¿Cómo es esto posible? ¿Significa ello que cuando hablamos y pensamos de estas otras cosas no hablamos de nada real? ¿o mas bien la realidad está mas poblada de lo que pensábamos y hay diferentes maneras de formar parte de la realidad además de la de existir de manera positiva y (...) concreta? En este libro trataremos de arrojar luz a estas y otras preguntas similares, poniendo atención a las estrategias argumentativas generales que suelen esgrimirse en esta rama de la filosofía. (shrink)

Various claims regarding intertheoretic reduction, weak and strong notions of emergence, and explanatory fictions have been made in the context of first-order thermodynamic phase transitions. By appealing to John Norton’s recent distinction between approximation and idealization, I argue that the case study of anyons and fractional statistics, which has received little attention in the philosophy of science literature, is more hospitable to such claims. In doing so, I also identify three novel roles that explanatory fictions fulfill in science. Furthermore, I (...) scrutinize the claim that anyons, as they are ostensibly manifested in the fractional quantum Hall effect, are emergent entities and urge caution. Consequently, it is suggested that a particular notion of strong emergence signals the need for the development of novel physical–mathematical research programs. (shrink)

Reduction between theories in physics is often approached as an a priori relation in the sense that reduction is often taken to depend only on a comparison of the mathematical structures of two theories. I argue that such approaches fail to capture one crucial sense of “reduction,” whereby one theory encompasses the set of real behaviors that are well-modeled by the other. Reduction in this sense depends not only on the mathematical structures of the theories, but also on empirical facts (...) about where our theories succeed at describing real systems, and is therefore an a posteriori relation.

Recent discussions of emergence in physics have focussed on the use of limiting relations, and often particularly on singular or asymptotic limits. We discuss a putative example of emergence that does not fit into this narrative: the case of phonons. These quasi-particles have some claim to be emergent, not least because the way in which they relate to the underlying crystal is almost precisely analogous to the way in which quantum particles relate to the underlying quantum field theory. But there (...) is no need to take a limit when moving from a crystal lattice based description to the phonon description. Not only does this demonstrate that we can have emergence without limits, but also provides a way of understanding cases that do involve limits. (shrink)

Paul Humphreys’ main aim in this wide-ranging and ambitious book is to defend a novel account of ontological emergence he refers to as transformational emergence. His secondary aims are many: to show how ontological emergence so understood can be usefully seen against the backdrop of a reductionist position he calls generative atomism ; to compare and contrast his preferred position with historical and contemporary alternatives; and to consider a range of scientific cases both as potential examples of ontological emergence and (...) of weaker forms of emergence stemming from our computational or conceptual limitations. Humphreys is clear from the outset that the range of scientific cases that satisfy certain positive criteria for emergence is too diverse for a single, unified account, and he is more concerned to highlight the differences that preclude such an account than to abstract away from them. The result is a mosaic of case studies, to which are applied a range of alternative conceptions of emergence, drawing out various similarities and differences between the cases, and assessing their credentials as emergent according to the various alternative conceptions considered.

We sketch the mechanistic approach to levels, contrast it with other senses of “level,” and explore some of its metaphysical implications. This perspective allows us to articulate what it means for things to be at different levels, to distinguish mechanistic levels from realization relations, and to describe the structure of multilevel explanations, the evidence by which they are evaluated, and the scientific unity that results from them. This approach is not intended to solve all metaphysical problems surrounding physicalism. Yet it (...) provides a framework for thinking about how the macroscopic phenomena of our world are or might be related to its most fundamental entities and activities. (shrink)

An elementary algebra identifies conceptual and corresponding applicational limitations in John Kemeny and Paul Oppenheim’s (K-O) 1956 model of theoretical reduction in the sciences. The K-O model was once widely accepted, at least in spirit, but seems afterward to have been discredited, or in any event superceeded. Today, the K-O reduction model is seldom mentioned, except to clarify when a reduction in the Kemeny-Oppenheim sense is not intended. The present essay takes a fresh look at the basic mathematics of K-O (...) comparative vocabulary theoretical term reductions, from historical and philosophical standpoints, as a contribution to the history of the philosophy of science. The K-O theoretical reduction model qualifies a theory replacement as a successful reduction when preconditions of explanatory adequacy and comparable systematicization are met, and there occur fewer numbers of theoretical terms identified as replicable syntax types in the most economical statement of a theory’s putative propositional truths, as compared with the theoretical term count for the theory it replaces. The challenge to the historical model developed here, to help explain its scope and limitations, involves the potential for equivocal theoretical meanings of multiple theoretical term tokens of the same syntactical type.

Inspite of the great success in many disciplines the program of reductionism has failed its genuine purpose. Systemtheory however has yielded a new concept of reductionism which we call reductionism by correspondence and which may imply a new understanding of the mind-body problem. The crucial operations of reductionism by correspondence are called idealization, interpretation and classification. They are used to optimize the description of a system. Nevertheless they lead to certain deficiencies which cannot be avoided in principle. We are therefore (...) driven to the assumption that natural systems can only be described as probabilistic systems. From this point of view nothing is said about the direction of the reduction.

Because biologization of psychiatric constructs does not involve derivation of laws, or reduce the number of entities involved, the traditional term of ‘reduction’ should be replaced. This paper describes biologization in terms of redefinition, which involves changing the definition of terms sharing the same extension. Redefinition obtains through triangulation and calibration, that is, respectively, detection of an object from two different spots, and tweaking parameters of detection in order to optimize the picture. The unity of the different views of the (...) same object does not occur through derivation from one of them, as reduction suggests, nor does it obtain through mechanistic unity or the goal of explaining one mechanism, as the phrase ‘mosaic unity’ suggests. Instead, it depends on finding a specific angle of observation, from which linguistic consistency matches sound localization in the brain, so that all observations make sense together, just as an anamorphic picture makes clear sense only when observed from the right spot.
