»Welche [Zugangsweise] man wählt, hängt weitgehend von der Fragestellung ab und davon, was man eigentlich erreichen möchte. Jede Betrachtung, die sich nur auf den einen Zugang beschränkt, ist einseitig. Es gibt hier ein Spannungsfeld, das es auszuhalten gilt«, so Ulrich Freund in einer Diskussion über das Verhältnis reduktionistischer und holistischer Verfahrensweisen in der Medizin. Während seine Äußerung durchaus von einem gewissen Optimismus geprägt ist, dass die Gegensätze zwischen Reduktionismus und Holismus nicht überbetont werden sollten, verdeckt sie doch ein grundlegendes (...) Problem. Dieses Problem besteht darin, dass es, wenn erst eine Reduktion vollzogen wurde, äußerst schwierig ist, die Ergebnisse der Reduktion wieder zu rekontextualisieren. Die Schwierigkeit besteht darin, die bereichsspezifischen Ergebnisse in ihrer Bedeutung für den umfassenden Kontext, aus dem sie gewonnen wurden, zu interpretieren. (shrink)

Die Autorinnen und Autoren präsentieren in diesem Buch Argumente, die die Unmöglichkeit des Reduktionismus aus philosophischer, naturwissenschaftlicher bzw. mathematisch-logischer Perspektive zu begründen suchen. Der Reduktionismus behauptet, dass Eigenschaften auch von komplexen Systemen vollständig auf ihre Bestandteile zurückgeführt werden können. Diese Position ist einflussreich, aber umstritten. Im Jahr 2019 hat der Kurt Gödel Freundeskreis einen Essaywettbewerb veranstaltet, um schlagende Argumente gegen den Reduktionismus zu finden. Unter den internationalen Teilnehmern waren neben weltweit führenden Forschern auch Wissenschaftler, die noch am (...) Beginn ihrer Kariere stehen. Dieser Band versammelt die Beiträge der Preisträger und weitere ausgewählte Aufsätze. Aus dem Inhalt: · Kausalität als antireduktionistisches Hausmittel – Martin Breul · Reduktionismus im Diskurs – Hanna Hueske · Monads, Types, and Branching Time – Kurt Gödel’s approach towards a theory of the soul – Tim Lethen · The limits of reductionism: thought, life, and reality – Jesse M.

In der Diskussion um personale Identität nehmen die einflussreichen Arbeiten Derek Parfits eine Sonderstellung ein, insofern Parfit nicht bestrebt ist, eines der gängigen Identitätskriterien zu verteidigen, sondern vielmehr behauptet, dass unsere alltäglichen wie philosophischen Vorstellungen von personaler Identität unrettbar inkohärent sind und deshalb aufgegeben werden sollten. In seinem Beitrag beleuchtet Sascha Settegast die verschiedenen Argumente, die Parfit für diese provokante These vorbringt, und unternimmt insbesondere den Versuch einer systematischen Dekonstruktion der wichtigsten Gedankenexperimente Parfits, die zeigen soll, dass sich diese Gedankenexperimente (...) auf eine Weise auflösen lassen, die unsere alltäglichen Intuitionen über personale Identität intakt belässt. Settegast entwickelt dabei die Grundzüge einer Konzeption personaler Identität, die sich einerseits von den gängigen neo-lockeanischen und animalistischen Ansätzen abgrenzt und andererseits bewusst an den zeitgenössischen Neo-Aristotelismus in der Ethik anknüpft, wie er etwa bei Philippa Foot und Michael Thomp-son anzutreffen ist. Die diachrone numerische Identität menschlicher Personen gründet nach Settegasts Auffassung darin, dass der Verlauf ihres Lebens eine zeitliche Einheit aufweist, die dadurch bedingt ist, dass ihre Lebensführung die menschliche Lebensform auf eine individuell charakteristische Weise exemplifiziert. Insofern dies aber nur durch Kultivierung der Tugen-den zu erreichen ist, handelt es sich laut Settegast bei personaler Identität letztlich nicht um eine Tatsache, die einfach vorliegt oder nicht, sondern um eine Aufgabe, die uns als Menschen gegeben ist und wesentlich darin besteht, in bewusster Orientierung auf das gute Leben hin ein stabiles, sich zeitlich durchhaltendes Selbst allererst auszubilden.

Kurt Gödel opposed the reductionist viewpoint of logical positivism. The arguments I give below show he is correct. The reductionist explanation he opposed is doomed to failure.

What is the best question reductionists would have to answer but cannot, and why exactly is there no reductionist answer to that question? To answer this question, we need to identify the relevant question.

Recently, the distinction between nature and technology has been increasingly questioned. We are told that the changes to nature made possible by technology had reached such dimensions that it was no longer possible to clearly differentiate between nature and technology. Against the critical voices, I argue for the possibility and necessity of applying a version of the distinction that I call “classical”. I begin by examining selected historical origins of this distinction and thereby discussing some of its critics debated today (...) – namely Hans Blumenberg, Bruno Latour, Donna Haraway and Philippe Descola. In the next section, I introduce a concept of hybrid of nature and technology, which is suitable for delimiting and differentiating the scope of the classical distinction. I also need the concept of hybrid in order to assess the current tendencies in the development of the nature-technology relation, which are the subject of the last section. Against the background of these tendencies, I conclude by compiling some arguments in favour of maintaining the classical distinction between nature and technology. (shrink)

Two criteria are proposed for characterizing the diverse and not yet perspicuous relations between nanotechnology and nature. They assume a concept of nature as that which is not made by human action. One of the criteria endorses a distinction between natural and artificial objects in nanotechnology; the other allows for a discussion of the potential nanotechnological modification of nature. Insofar as current trends may be taken as indicative of future development, nanotechnology might increasingly use the model of nature as a (...) point of orientation, while many of its products will continue to be clearly distinguished from nature.

Mit diesem Beitrag möchte ich der Frage nachgehen, ob die Gegenstände, Vorhaben oder Konzeptionen der Nanotechnologie geeignet sind, zu einer tiefgreifenden Veränderung bisher vorherrschender Natur-Technik-Verständnisse zu führen. Von besonderem Interesse sind dabei nichtwissenschaftliche Auffassungen, von denen ich exemplarisch die der Lebenswelt vorstellen werde. In ihrer aristotelischen Verfassung folgt sie einer kategorialen Entgegensetzung von Natur und Technik. Natur zeichnet sich demnach durch eine nicht auf Technik reduzierbare Selbstbewegung aus, Technik geht hingegen ganz im menschlichen Handeln auf (Abschnitt 1). Das nanotechnologische Naturverständnis (...) läuft dem lebensweltlichen Verständnis insofern zuwider, als es keine kategoriale Abgrenzung zur Technik kennt. Es lassen sich verschiedene Naturbegriffe der Nanotechnologie unterscheiden, von denen ich zwei Gruppen hervorhebe: die naturalistische und die der Natur-Technik-Differenz (Abschnitt 2). Letztere enthält wiederum zwei Bedeutungen. Zum einen meint Natur das gesetzmäßig Verfaßte. Als solches stellt sie eine unüberschreitbare Voraussetzung und Grenze des nanotechnologisch Machbaren dar. Eine steigende Relevanz der Nanotechnologie (wie der wissenschaftlichen Technik überhaupt) würde dieser Bedeutung zu größerer kultureller Tragweite gegenüber der lebensweltlichen Entgegensetzung verhelfen (Abschnitt 3). Zum anderen bezeichnet Technik in der Nanotechnologie aber, wie auch in der Lebenswelt, das vom Menschen Hergestellte (ohne jedoch von Natur kategorial getrennt zu sein). Wegen dieser Gemeinsamkeit trägt die Nanotechnologie trotz ihrer differenten Naturauffassung zur Stützung des lebensweltlichen Technikverständnisses bei. Sie vermag unter bestimmten Bedingungen mit ihren Methoden den der lebensweltlichen Wahrnehmung nicht zugänglichen künstlichen Ursprung von nanotechnologischen Gegenständen nachzuweisen. Wenn diese Identifikation prinzipiell ausgeschlossen ist, fallen die nanotechnologischen Gegenstände der Natur zu. Ansonsten bilden sie Hybride, in denen Natur und Technik mitunter in nicht mehr auftrennbarer Verschränkung vorliegen. Diese Untrennbarkeit ist nicht spezifisch für die Nanotechnologie und setzt der Identifikation nanotechnologischer Eingriffe keine neue Grenze (Abschnitt 4). Abschließend gehe ich auf den Einfluß der Nanotechnologie auf das lebensweltliche Naturverständnis ein, d. h. auf den erwartbaren Einfluß von nanotechnologischen Produkten und die Bedeutung der Grenzen der nanotechnologischen Unterscheidbarkeit von Natur und Technik in der Lebenswelt (Abschnitt 5).

Among contemporary epistemologists of testimony, David Hume is standardly regarded as a ‘global reductionist’, where global reductionism requires the hearer to have sufficient first-hand knowledge of the facts in order to individually ascertain the reliability of the testimony in question. In the present paper, I argue that, by construing Hume’s reductionism in too individualistic a fashion, the received view of Hume on testimony is inaccurate at best, and misleading at worst. Overall, Hume is much more willing to regard (...) testimonial acceptance as a natural response to testimony than has traditionally been thought. In particular, Hume believes that indirect evidence of human nature and of the social world around us, can take the place of first-hand evidence of the track record of individual speakers or specific classes of testimony. In developing this interpretation of Hume’s views on testimony, the present paper draws on discussions found in the Treatise, the Enquiry, and in Hume’s writings on historical knowledge. In der zeitgenössischen Debatte um den erkenntnistheoretischen Status zeugnisbasiertenWissens wird gern auf David Hume als den Urheber eines „globalen Reduktionismus“ verwiesen, demzufolge der Zeugnisempfänger über ausreichend empirische Belege für die Verlässlichkeit des betreffenden Zeugnisses verfügen muss. Im vorliegenden Aufsatz soll gezeigt werden, dass die in der Literatur vorherrschende Meinung ein übertrieben „individualistisches“ Bild von Humes Reduktionismus zeichnet; dadurch wird Humes Position in der gegenwärtigen Debatte ungenau und bisweilen irreführend wiedergegeben. Bei genauerer Betrachtung erweist sich Hume als ausgesprochen aufgeschlossen gegenüber dem Akzeptieren fremden Zeugnisses und sieht darin eine Art Grundmuster im testimonialen Umgang mit anderen. Insbesondere konzediert Hume, dass indirekt erworbenes Wissen um die menschliche Natur und die soziale Welt an die Stelle direkter Belege für die Verlässlichkeit einzelner Zeugen treten kann. Die im vorliegenden Aufsatz entwickelte Neuinterpretation stützt sich auf den Treatise, den Enquiry und auf Humes Schriften zum Problem der historischen Erkenntnis. (shrink)

History Without Causality. How Contemporary Historical Epistemology Demarcates Itself From the Sociology of Scientific Knowledge. Contemporary proponents of historical epistemology often try to delimit their enterprise by demarcating it from the sociology of scientific knowledge and other sociologically oriented approaches in the history of science. Their criticism is directed against the use of causal explanations which are deemed to invite reductionism and lead to a totalizing perspective on science. In the present article I want to analyse this line of (...) criticism in what I consider are two paradigmatic works of contemporary historical epistemology: Lorraine Daston's und Peter Galison's Objectivity and Hans‐Jörg Rheinberger's Toward a History of Epistemic Things. I first present their arguments against the sociological and causal analysis of scientific knowledge and practice and then try to defend sociological work in the history of science against their charges. I will, however, not do so by defending causal explanations directly. Rather, I will show that the arguments against sociological analysis put forward in contemporary historical epistemology, as well as historical epistemology's own models of historical explanation and narration, bear problematic consequences. I argue that Daston, Galison and Rheinberger fail to create productive resonances between macro‐ and microhistorical perspectives, that they reproduce an internalist picture of scientific knowledge, and finally that Rheinberger's attempt to deconstruct the dichotomy between subject and object leads him to neglect questions about the political dimension of scientific research.

The part‐whole and element‐system relations are usually not given a temporal interpretation. Taking a thesis of Father Bochenski as a starting point , the author first gives an adequate temporal interpretation of this thesis. Then, he shows that a divergence arises, in non‐static systems, between the system itself and the mereological sum corresponding to it at a certain instant. Therefore, any reductionism has to confront the generally neglected problem of this divergence. Résumé Les relations partie‐tout et élément‐système ne sont (...) pas habituellement interprétées de manière temporelle lorsqu'elles sont approachées de manière formelle. On prend ici pour point de départ une thèse formulée par le P. Bochenski, "tout élément d'un système est une partie propre de ce système", dont on donne d'abord une interpretation temporelle adéquate. On met ensuite en évidence la divergence, pour les systèmes non statiques, du système et de la somme méréologique qui lui correspond en un instant donné. Le réductionnisme doit done affronter le problème généralement négligé de cette divergence. -/- Zusammenfassung Gewöhnlich werden die Relationen zwischen Teil und Ganzem und zwischen Element und System nicht zeitlich interpretiert, wenn sie formal behandelt werden. Von einer These von P. Bochenski ausgehend versucht man zuerst, dieser These eine angemessene zeitliche Interpretation zu geben. Dann zeigt man, dass es bei nicht‐statischen Systemen eine Divergenz zwischen dem System und der ihm zu einer bestimmten Zeit entsprechenden mereologischen Summe gibt. Das sich daraus für den Reduktionismus ergebende Problem wird meist vernächlassigt. (shrink)

How was the hypothetical character of theories of experience thought about throughout the history of science? The essays cover periods from the middle ages to the 19th and 20th centuries. It is fascinating to see how natural scientists and philosophers were increasingly forced to realize that a natural science without hypotheses is not possible.

Nach dem vorherrschenden reduktionistischen Selbstverständnis der Physik sind höherstufige physikalische Theorien als Grenzfall in grundlegenderen Theorien enthalten und daher im Prinzip überflüssig. Höherstufige Theorien werden laut dieser Sichtweise nur aus dem pragmatischen Grund verwendet, für ihren jeweiligen Bereich besser anwendbar zu sein. Es gibt zwar verschiedene Modelle der Reduktion physikalischer Theorien, dieses Selbstverständnis lässt sich aber am besten mit dem Modell der eliminativen Reduktion auf den Begriff bringen, Dieser Beitrag zeigt, dass dieses reduktionistische Verhältnis zwischen klassischer und Quantenmechanik nicht besteht.

_Conservative Reductionism_ sets out a new theory of the relationship between physics and the special sciences within the framework of functionalism. It argues that it is wrong-headed to conceive an opposition between functional and physical properties and to build an anti-reductionist argument on multiple realization. By contrast, all properties that there are in the world, including the physical ones, are functional properties in the sense of being causal properties, and all true descriptions that the special sciences propose can in principle (...) be reduced to physical descriptions by means of functional reduction, despite multiple realization. The book develops arguments for from the metaphysics of properties and the philosophy of physics. These arguments lead to a conservative ontological reductionism. It then develops functional reduction into a fully-fledged, conservative theory reduction by means of introducing functional sub-types that are coextensive with physical types, illustrating that conservative reductionism by means of case studies from biology.

After the discovery of the structure of DNA in 1953, scientists working in molecular biology embraced reductionism—the theory that all complex systems can be understood in terms of their components. Reductionism, however, has been widely resisted by both nonmolecular biologists and scientists working outside the field of biology. Many of these antireductionists, nevertheless, embrace the notion of physicalism—the idea that all biological processes are physical in nature. How, Alexander Rosenberg asks, can these self-proclaimed physicalists also be antireductionists? With (...) clarity and wit, Darwinian Reductionism navigates this difficult and seemingly intractable dualism with convincing analysis and timely evidence. In the spirit of the few distinguished biologists who accept reductionism—E. O. Wilson, Francis Crick, Jacques Monod, James Watson, and Richard Dawkins—Rosenberg provides a philosophically sophisticated defense of reductionism and applies it to molecular developmental biology and the theory of natural selection, ultimately proving that the physicalist must also be a reductionist.

Contrary to a widespread belief, this book establishes that ontological and epistemological reductionism stand or fall together.

Causal reductionism is the widespread assumption that there is no room for additional causes once we have accounted for all elementary mechanisms within a system. Due to its intuitive appeal, causal reductionism is prevalent in neuroscience: once all neurons have been caused to fire or not to fire, it seems that causally there is nothing left to be accounted for. Here, we argue that these reductionist intuitions are based on an implicit, unexamined notion of causation that conflates causation (...) with prediction. By means of a simple model organism, we demonstrate that causal reductionism cannot provide a complete and coherent account of ‘what caused what’. To that end, we outline an explicit, operational approach to analyzing causal structures. (shrink)

Reductionism concerns a set of ontological and epistemological claims, and methodological strictures based on them, about the relationship between two different scientific domains. The critical assumption is that one of these domains is privileged over the other in the sense that the concepts, rules, laws, and other elements of the privileged domain can be used to specify, constitute, or account for those of the other “reduced” domain. This specification often consists of explanation, such that the “reducing” domain is epistemically (...) privileged over the reduced one. Explanations of this type are “reductionist” (or, are “reductions”) and reductionism is then the thesis that such explanations will always be forthcoming or at least are possible in principle. Reductionism is most plausible if the entities of the reduced domain can be interpreted as arising from (e.g., as aggregates of) entities of the reduced domain. This ontological claim is controversial but motivates many reductionist theses and associated scientific research programs. Thus, epistemological and ontological claims about reductionism have the methodological implication that they should govern and guide scientific research. When such research proves to be fruitless over a period of time, the associated reductionist claims themselves become suspect. Although issues connected with reductionism arise in the physical and social sciences, most attention to reductionism in philosophy of science over the last few decades has focused on the biological sciences, especially after the advent of molecular biology made it plausible to believe that biological phenomena can be uniformly explained (in detail) from their physical basis. However, the program of finding such explanations has a long philosophical history often couched in terms of seeking “mechanical,” “mechanistic,” or “materialistic” explanations. The contrast here is with traditional vitalism and various forms of teleology and holism. (shrink)

Reductionism encompasses a set of ontological, epistemological, and methodological claims about the relation of different scientific domains. The basic question of reduction is whether the properties, concepts, explanations, or methods from one scientific domain (typically at higher levels of organization) can be deduced from or explained by the properties, concepts, explanations, or methods from another domain of science (typically one about lower levels of organization). Reduction is germane to a variety of issues in philosophy of science, including the structure (...) of scientific theories, the relations between different scientific disciplines, the nature of explanation, the diversity of methodology, and the very idea of theoretical progress, as well as to numerous topics in metaphysics and philosophy of mind, such as emergence, mereology, and supervenience.

Methodological reductionists practice ‘wannabe reductionism’. They claim that one should pursue reductionism, but never propose how. I integrate two strains in prior work to do so. Three kinds of activities are pursued as “reductionist”. “Successional reduction” and inter-level mechanistic explanation are legitimate and powerful strategies. Eliminativism is generally ill-conceived. Specific problem-solving heuristics for constructing inter-level mechanistic explanations show why and when they can provide powerful and fruitful tools and insights, but sometimes lead to erroneous results. I show how (...) traditional metaphysical approaches fail to engage how science is done. The methods used do so, and support a pragmatic and non-eliminativist realism. (shrink)

Reductionism’s approach brings together many of the most interesting questions today in philosophy and in science . It also presents a brief history of how reductionism has developed in Western philosophy and religion, with reference to Indian philosophy on certain issues.

The paper raises some difficulties for the typical motivations behind set reductionism, the view that sets are reducible to entities identified independently of set theory.

In this paper, I argue that anti-reductionist moral realism still has trouble explaining supervenience. My main target here will be Russ Shafer-Landau's attempt to explain the supervenience of the moral on the natural in terms of the constitution of moral property instantiations by natural property instantiations. First, though, I discuss a recent challenge to the very idea of using supervenience as a dialectical weapon posed by Nicholas Sturgeon. With a suitably formulated supervenience thesis in hand, I try to show how (...) Shafer-Landau's proffered strategy to explain supervenience not only fails to explain supervenience, but that it also has a number of implausible consequences. The more general lesson is that strategies which may work well for explaining supervenience in the philosophy of mind and other areas cannot be assumed to carry over successfully to the metaethical context. We should therefore treat so-called `companions in guilt' arguments in this area of philosophy with considerable skepticism. Key Words: expressivism • moral realism • non-naturalism • reductionism • supervenience • trope. (shrink)

This paper attempts to show how a reductionist approach to the metaphysics of personal identity might well be most compatible with a form of contractualism, not utilitarianism.

Kim’s causal exclusion argument purports to demonstrate that the non-reductive physicalist must treat mental properties (and macro-level properties in general) as causally inert. A number of authors have attempted to resist Kim’s conclusion by utilizing the conceptual resources of Woodward’s interventionist conception of causation. The viability of these responses has been challenged by Gebharter, who argues that the causal exclusion argument is vindicated by the theory of causal Bayesian networks (CBNs). Since the interventionist conception of causation relies crucially on CBNs (...) for its foundations, Gebharter’s argument appears to cast significant doubt on interventionism’s anti-reductionist credentials. In the present article, we both (1) demonstrate that Gebharter’s CBN-theoretic formulation of the exclusion argument relies on some unmotivated and philosophically significant assumptions (especially regarding the relationship between CBNs and the metaphysics of causal relevance), and (2) use Bayesian networks to develop a general theory of causal inference for multi-level systems that can serve as the foundation for an anti-reductionist interventionist account of causation.1.

In the context of the free will debate, both compatibilists and event-causal libertarians consider that the agent’s mental states and events are what directly causes her decision to act. However, according to the ‘disappearing agent’ objection, if the agent is nothing over and above her physical and mental components, which ultimately bring about her decision, and that decision remains undetermined up to the moment when it is made, then it is a chancy and uncontrolled event. According to agent-causalism, this sort (...) of problem can be overcome if one realizes that the agent herself, as an irreducible substance, is the true originator of her actions. I’ll present arguments that favor this view. Event-causalists have countered that if the agent identifies with some of the inner states that play the self-determining causal role in bringing about the action, then it is as though the action was directly caused by herself. I’ll object that this is not a distinctive aspect of free agency. Agent-causalism has been criticized from most naturalistically inclined fronts, and it must address risks of implausibility, contradiction and unintelligibility. Even though I’ll acknowledge these challenges, I’ll still argue that libertarian free will cannot be defended by any reductionist alternative, and that agent-causalism does not conflict with contemporary science but only with some of its unproven assumptions.

The present volume aims at giving a discussion ot the problems ot reductionism in contemporary life sciences. It contains six papers which deals with reduction/reductionism in different fields ot biological research. Also, the holistic perspective, 1. e. the systems view, is discussed in some ot the papers. The message ot this discussion Is that - whereas reductionism is indeed an important strategy - the systems approach is needed. It is argued by some ot the authors that organisms (...) are complex systems and not just heaps of molecules, 50 that the analytical method does not suffice. Recent developments in systems theory offer the possibility to install a more comprehensive view ot living systems what can be seen particularly in the field ot evolutionary biology. It is true that any organismic activity is molecular, this is to say that it is based on molecular mechanisms. But it is also true that the whole organism displays certain patterns ot behavior which are not just molecular. Any organism can be described as a system ot different levels ot organization different levels ot order and complexity - and it is important, theretore, to study all ot the organizational levels and to see their peculiarities. It should be obvious, however, that there is not one problem ot reduction/reductionism, but that there are many problems linked together and that these problems appear at different levels ot biological research and bio philosophical reflections.

Nonreductive physicalists have a causal exclusion problem. Given certain theses all physicalists accept, including psychophysical supervenience and the causal closure of the physical realm, it is difficult to see how irreducible mental phenomena could make a causal difference to the world.

With the advent of the Human Genome Project there have been many claims for the genetic origins of complex human behavior including insanity, criminality, and intelligence. But what does it really mean to call something 'genetic'? This is the fundamental question that Sahotra Sarkar's book addresses. The author analyses the nature of reductionism in classical and molecular genetics. He shows that there are two radically different kinds of reductionist explanation: genetic reduction (as found in classical genetics) and physical reduction (...) (found in molecular genetics). This important book clarifies the meaning of the term 'genetic', shows how molecular studies have affected genetics, and provides the philosophical background necessary to understand the debates over the Human Genome Project. It will be of particular interest to professionals and students in the philosophy of science, the history of science, and the social studies of science, medicine, and technology. (shrink)

. Nonreductive physicalism, as opposed to reductionism, enjoys wide popularity by virtue of being regarded as comporting with the traditional image of human beings as free and ontologically unique without the difficulties of mind-body dualism. A consideration of reasons, both good and bad, for which reductionism is rejected suggests instead that the move to nonreductive physicalism does nothing to mitigate the implications of a physicalist account of human nature.

(added for 2013 upload): This chapter compares classical dualist and reductionist views of phenomenal consciousness with an alternative, reflexive way of viewing the relations amongst consciousness, brain and the external physical world. It argues that dualism splits the universe in two fundamental ways: in viewing phenomenal consciousness as having neither location nor extension it splits consciousness from the material world, and subject from object. Materialist reductionism views consciousness as a brain state or function (located and extended in the brain) (...) which eliminates the consciousness/material world split, but retains the split of subject from object. The chapter argues that neither dualism nor reductionism accurately describes the phenomenal world; consequently they each provide a misleading understanding of phenomenal consciousness. Reflexive monism follows the contours of everyday experience, thereby allowing a more unified understanding of how phenomenal consciousness relates to the brain and external physical world that is consistent both with the findings of science and with common sense. The chapter goes on to consider how phenomenal objects relate to real objects, perceptual projection, how phenomenal space relates to physical space, whether the brain is in the world or the world in the brain, and why this matters for science.

Reductionists are those who take one theory or phenomenon to be reducible to some other theory or phenomenon. For example, a reductionist regarding mathematics might take any given mathematical theory to be reducible to logic or set theory. Or, a reductionist about biological entities like cells might take such entities to be reducible to collections of physico-chemical entities like atoms and molecules. The type of reductionism that is currently of most interest in metaphysics and philosophy of mind involves the (...) claim that all sciences are reducible to physics. This is usually taken to entail that all phenomena (including mental phenomena like consciousness) are identical to physical phenomena. The bulk of this article will discuss this latter understanding of reductionism. (shrink)

Reductionism and holism, that is, antireductionism, are two of the prevailing paradigms within the philosophy of biology. Reductionists strive to understand biological phenomena by reducing them to a series of levels of complexity with each lower level forming the foundation for the subsequent level, by mapping such biological phenomena inasmuch as possible to the principal phenomena within the fundamental sciences of chemistry and physics. In this way, complex phenomena can be reduced to assemblages of more elementary explananda. Holism, in (...) counterpart, claims that there independently exist phenomena arising from ordered levels of complexity that have intrinsic causal power and cannot be reduced in this way. When dealing with the nature of biology and its unique foundations of essentialism, determinism and ethics, the pedagogical lens through which these foundations are conveyed to learners could provide a limited perspective if only the reductive approach is followed as it would not sensitise learners to the true complexity of the phenomenon of life and the study thereof, and it is the purpose of this article to frame the reductionist–antireductionist debate in order to illustrate this.Contribution: This article contributes new knowledge to the field of the philosophy of science; more specifically, the philosophy of biology by critically evaluating the pervasive dialectic between the theoretical frameworks of reductionism and antireductionism and alluding to the pedagogical consequences thereof.

In previous work, I defend the following disparity between moral and epistemic facts: whereas moral facts are irreducibly normative, epistemic facts – facts such as that some subject is epistemically justified in believing something – are reducible to facts from some other domain (such as facts about probabilities). This moral-epistemic disparity is significant because it undercuts an important kind of argument for robust moral realism. My defense of epistemic reductionism and of the moral-epistemic disparity has been criticized by Richard (...) Rowland (2013) and by Terence Cuneo and Christos Kyriacou (forthcoming). This paper aims to rebut these criticisms and, more generally, to clarify and strengthen the case for epistemic reductionism and the moral-epistemic disparity. (shrink)

This paper characterizes a form of materialism which is strongly anti?reductionist with regard to mental predicates. It argues against the functionalist views of writers such as Brian Loar on the basis that the counterfactual interdependencies of intentional states are governed by constraints of rationality embodied in semantic links which cannot be captured in non?intentional, functionalist terms. However, contrary to what is commonly supposed, such anti?reductionism requires neither instrumentalism about the mental nor opposition to a causal explanatory view of intentional (...) explanation. The paper therefore aims to show that a realist causal explanatory view of psychological states is compatible with a non?reductive materialism (a position excluded by Brian Loar in his recent book Mind and Meaning).

This chapter investigates the prospects for an important position that falls under the "mere patterns" approach: what, for reasons that will emerge, the author calls"Humean reductionism" about laws of nature, a view championed perhaps most prominently by David Lewis. He reviews some of the most interesting arguments against this position from the literature, and adds some of his own that, he thinks, are more effective. The chapter considers how the best system account (BSA) would apply to the Newtonian particle (...) world. The BSA has been challenged in a wide variety of ways: it violates certain intuitions; It makes a hash out of the connection between laws on the one hand, and counterfactuals, explanation, and induction on the other. The author thinks that the problem he has raised‐challenging though he hopes it is, is really an occasion for the Humean reductionist to sharpen his position still further. (shrink)

This paper's ?I examines Derek Parfit's main, metaphysical, argument for reductionism about personal identity. ?II considers three possible ethical arguments for reductionism, and suggests a new approach to the question of what matters about personal identity which has to do with the notion of an ethical narrative.

The practice of reductionism in science and philosophy includes attempts to essentialize human persons, which can lead to serious social problems. Reductionism is not necessary, as comparative philosophers and alternative-thinking scientists have shown.

The case of very young children is a test case for the plausibility of reductionism about testimonial warrant. Reductionism requires reductive reasons, reductively justified and actively deployed for testimonial justification. Though nascent language-users enjoy warranted testimony based beliefs, they do not meet these three reductionist demands. This paper clearly formulates reductionism and the infant/child objection. Two rejoinders are discussed: an influential conceptual argument from Jennifer Lackey’s paper “Testimony and the Infant/Child Objection” and the growing empirical evidence from (...) developmental psychology on selective trust in children. Neither Lackey’s argument nor the empirical evidence vindicate reductionism. (shrink)

Reductionist forms of moral realism, such as naturalist realism, are often thought immune to epistemological objections that have been raised against nonnaturalist realism in the form of reliability worries or evolutionary debunking arguments.
