»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)

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.

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.

Die philosophischen Folgerungen der Synergetik, einer interdisziplinären Theorie der Evolution und Selbstorganisation komplexer nichtlinearer Systeme, werden in diesem Artikel zur Diskussion gestellt. Das sind der weltanschauliche Sinn des Begriffs von der „Nichtlinearität“, die konstruktive Rolle des Chaos in der Evolution, eine neue Vorstellung von diskreten Spektren evolutionärer Wege in komplexen Systemen, die Prinzipien des Aufbaus von komplexem evolutionärem Ganzen, der Integration von komplexen Strukturen, die sich mit verschiedenen Geschwindigkeiten entwickeln, die Methoden des nichtlinearen Managements komplexer Systeme. Die Synergetik entdeckt allgemeingültige (...) Gesetzmäßigkeiten der Strukturbildung, der Selbstorganisation und der Evolution komplexer Systeme und gehört deswegen zu der Richtung des Universalismus.

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.

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.

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.

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)

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.

Das sich daraus für den Reduktionismus ergebende Problem wird meist vernächlassigt. (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.

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)

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).

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

Can there be higher level laws of nature even though everything is reducible to the fundamental laws of physics? The computer science notion of level of abstraction explains how there can be.

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.

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)

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)

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. This article establishes that reductionist realist views can only explain the reliability of our moral beliefs at the cost of incurring repugnant first-order conclusions.

_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.

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.

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)

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)

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)

For nearly thirty years, there has been a consensus (at least in English-speaking countries) that reductionism is a mistake and that there are autonomous special sciences. This consensus has been based on an argument from multiple realizability. But Jaegwon Kim has argued persuasively that the multiple realizability argument is flawed.1 I will sketch the recent history of the debate, arguing that much --but not all--of the anti-reductionist consensus survives Kim's critique. This paper was originally titled "Anti-Reductionism Strikes Back", (...) but in the course of writing the paper, I came to think that the concepts used in the debate would not serve either position very well.

The contrast between the strategies of research employed in reductionism and holism masks a radical contradiction between two different scientific philosophies. We concentrate in particular on an analysis of the key philosophical issues which give structure to holistic thought. A first (non-exhaustive) analysis of the philosophical tradition will dwell upon: a) the theory of emergence: each level of organisation is characterised by properties whose laws cannot be deduced from the laws of the inferior levels of organisation (Engels, Morgan); b) (...) clarification of the relations between the “whole” and the “parts” (Woodger, Needham); c) the ontological or epistemological nature of the emergent properties; are they a phenomenological reality or solely an artefact of the state of our knowledge? (Pepper, Henle, Hempel and Oppenheim); d) the proposition of the holistic theoretical and methodological model ( Novikoff, Feibleman). I then go on to examine the differences that exist between the reductionist and the holistic approaches at various levels of analysis: that is to say, the differences which affect their ontologies, methodologies and epistemologies respectively. I attempt to understand the spirit of a holistic approach to ecology by analyzing the major work of E.P. Odum Fundamentals of ecology (1953, 1959, 1971). I set forward what might be meant by the “holistic approach”, which is implicated in all the different levels of organisation at which the problem of “complexity” is debated. Ecology presents itself as an “holistic science” and Odum’s book offers a vision of the world which dates far back in the history of philosophy. By looking at the three different editions of this fundamental text on ecology, we may become aware of the evolution of Odum’s thought. In fact, only in the third and last edition is there a conscious appropriation of the holistic approach (by using the theoretical models of Feibleman who, for his part, refers to Novikoff). However, even when formally referring to the theory of emergence (that is to say the ontological nucleus of every holistic approach), Odum’s systemic analysis presents the same logical errors, which push him back into the reductionist domain. Above all, in his examination of the main concepts of “population”, “community” and “ecosystem”, there is a misunderstanding of the profound difference between “collective properties” and “emergent properties”. Moreover, the cybernetic models of Odum’s systemic analysis (introduced into ecology by Margalef), allowed him to vastly oversimplify his methodological task: in fact, neither how many levels nor which levels of organization are fundamental for the study of each individual level is clearly marked. Finally, Odum analyses the ecosystem as composed of energetic flux and cycles of matter, referring to the trophic-dynamic vision of Lindeman. That is to say, in my opinion, he juxtaposes a reductionistic methodology and epistemology to an holistic ontology. (shrink)

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.

This paper analyses the anti-reductionist argument from renormalisation group explanations of universality, and shows how it can be rebutted if one assumes that the explanation in question is captured by the counterfactual dependence account of explanation.

In recent years, a ''change in attitude'' in particle physics has led to our understanding current quantum field theories as effective field theories (EFTs). The present paper is concerned with the significance of this EFT approach, especially from the viewpoint of the debate on reductionism in science. In particular, I shall show how EFTs provide a new and interesting case study in current philosophical discussion on reduction, emergence, and inter-level relationships in general.

I consider a problem for functional reductionism, based on the following tension. Say that b is functionally reduced to a. On the one hand, a and b turn out to be identical, and identity is a symmetric relation. On the other hand, functional reductionism implies that a and b are asymmetrically related: if b is functionally reduced to a, then a is not functionally reduced to b. Thus, we ask: how can a and b be asymmetrically related if (...) they are the same thing? I propose a solution to this tension, by distinguishing between ontological levels and levels of description.

Nathan Salmon, in his paper Trans-World Identification and Stipulation (1996) purports to give a proof for the claim that facts concerning trans-world identity cannot be conceptually reduced to general facts. He calls this claim ‘Extreme Haecceitism.’ I argue that his proof is fallacious. However, I also contend that the analysis and ultimate rejection of his proof clarifies the fundamental issues that are at stake in the debate between the reductionist and haecceitist solutions to the problem of trans-world identity. These issues (...) hinge on the ability of modal logic and possible worlds semantics to draw a hard and fast distinction between the logic and the metaphysics of modal logic. I shall claim that the considerations in this paper call into question the viability of such a distinction. (shrink)

Scientists have always attempted to explain the world in terms of a few unifying principles. In the fifth century B.C. Democritus boldly claimed that reality is simply a collection of indivisible and eternal parts or atoms. Over the centuries his doctrine has remained a landmark, and much progress in physics is due to its distinction between subjective perception and objective reality. This book discusses theory reduction in physics, which states that the whole is nothing more than the sum of its (...) parts: the properties of things are directly determined by their constituent parts. Reductionism deals with the relation between different theories that address different levels of reality, and uses extrapolations to apply that relation in different sciences. Reality shows a complex structure of connections, and the dream of a unified interpretation of all phenomena in several simple laws continues to attract anyone with genuine philosophical and scientific interests. If the most radical reductionist point of view is correct, the relationship between disciplines is strictly inclusive: chemistry becomes physics, biology becomes chemistry, and so on. Eventually, only one science, indeed just a single theory, would survive, with all others merging in the Theory of Everything. Is the current coexistence of different sciences a mere historical venture which will end when the Theory of Everything has been established? Can there be a unified description of nature? Rather than an analysis of full reductionism, this book focuses on aspects of theory reduction in physics and stimulates reflection on related questions: is there any evidence of actual reduction? Are the examples used in the philosophy of science too simplistic? What has been endangered by the search for (the) ultimate truth? Has the dream of reductionist reason created any monsters? Is big science one such monster? What is the point of embedding science Y within science X, if predictions cannot be made on that basis? (shrink)

Syntactic Reductionism, as understood here, is the view that the ‘logical forms’ of sentences in which reference to abstract objects appears to be made are misleading so that, on analysis, we can see that no expressions which even purport to refer to abstract objects are present in such sentences. After exploring the motivation for such a view, and arguing that no previous argument against it succeeds, sentences involving generalized quantifiers, such as ‘most’, are examined. It is then argued, on (...) this basis, that Syntactic Reductionism is untenable. (shrink)

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)

Husserl’s phenomenology is what is used, and then the conception of “bracketing reality” is modelled to generalize Peano arithmetic in its relation to set theory in the foundation of mathematics. The obtained model is equivalent to the generalization of Peano arithmetic by means of replacing the axiom of induction with that of transfinite induction. A comparison to Mach’s doctrine is used to be revealed the fundamental and philosophical reductionism of Husserl’s phenomenology leading to a kind of Pythagoreanism in the (...) final analysis.

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.

In this article, we analyse how researchers use the categories of race and ethnicity with reference to genetics and genomics. We show that there is still considerable conceptual “messiness” (despite the wide-ranging and popular debate on the subject) when it comes to the use of ethnoracial categories in genetics and genomics that among other things makes it difficult to properly compare and interpret research using ethnoracial categories, as well as draw conclusions from them. Finally, we briefly reconstruct some of the (...) biases of reductionism to which geneticists (as well as other researchers referring to genetic methods and explanations) are particularly exposed to, and we analyse the problem in the context of the biologization of ethnoracial categories. Our work constitutes a novel, in-depth contribution to the debate about reporting race and ethnicity in biomedical and health research. First, we reconstruct the theoretical background assumptions about racial ontology which researchers implicitly presume in their studies with the aid of a sample of recent papers published in medical journals about COVID-19. Secondly, we use the typology of the biases of reductionism to the problem of biologization of ethnoracial categories with reference to genetics and genomics. (shrink)

showing what makes causal facts both true and accessible enough for us to have the knowledge of them that we ordinarily take ourselves to have. Some current approaches to analyzing causation were once resisted. First, analyses that use the counterfactual conditional were viewed with suspicion because philosophers also sought (and still do seek) similar understanding of counterfactual facts. Since the same can be said for the other nomic concepts--causation, lawhood, explanation, chance, dispositions, and their conceptual kin--philosophy demonstrated a preference for (...) non-nomic definitions of causation, analytic completions of (S) with no nomic terms in the analysans. Recently, however, philosophers have been less demanding regarding what terms may be used. Attention has been given to analyzing causation in terms of chance, the counterfactual conditional, and lawhood. If we reserve the term ‘causal’ for the terms and concepts that have extremely obvious connections.. (shrink)

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 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)
