Reduction

This essay outlines a hierarchical framework of Reality that allows for degrees of Reality. I use Reality (with a capital “R”) to designate reality in a primitive, metaphysical sense. Reality, grounding, and essence are the key elements of the framework presented here. I assume that Reality must have a fundamental level and all fundamental phenomena must be Real. Moreover, I postulate that everything non-fundamental is ultimately grounded in the fundamental Real. But what about the Reality of the non-fundamental? I argue (...) that it is possible for non-fundamental phenomena to be Real, Unreal, or Semi-Real. The framework developed here accommodates these possibilities and illuminates them using the notion of essence. I argue that the essential nature of a phenomenon determines its degree of Reality. The framework does not assume that Reality must have degrees but only that it may have degrees. Its theoretical attractiveness consists in its ability to accommodate many diverse intuitions about grounding, help us better understand and classify theories about grounding, and illuminate Reality and its possible degrees.

It is not unusual among particle physicists to find the belief that elementary particles and forces determine everything in physics, chemistry, biology, geology, physiology all the way up to human behaviour. It is not just that physics underlies everything in the universe; it is the belief that everything in the universe reduces to the play of elementary particles under forces. Yet, there are other physicists who argue that this is an oversimplification of the relationship between physics and other domains. This (...) book explores these debates and proposes a physics-motivated conception of emergence that leaves behind many of the problematic intuitions shaping the philosophical conceptions. It would be suitable for physicists, scientists, undergraduate and postgraduate science students interested in reduction and emergence debates. (shrink)

Functional reductionism characterises inter-theoretic reduction as the recovery of the upper-level behaviour described by the reduced theory in terms of the lower-level reducing theory. For instance, finding a statistical mechanical realiser that plays the functional role of thermodynamic entropy allows for establishing a reductive link between thermodynamics and statistical mechanics. This view constitutes a unique approach to reduction that enjoys a number of positive features, but has received limited attention in the philosophy of science. -/- This paper aims to clarify (...) the meaning of functional reductionism in science, with a focus on physics, to define both its place with respect to other approaches to reduction and its connection to ontology. To do so, we develop and explore two alternative frameworks for functional reduction, called Syntactic Functional Reductionism and Semantic Functional Reductionism. They represent two different possible stances on the view that expand and improve the basic functional reductionist approach along different lines, and make clear how the approach works in practice. The former elaborates on David Lewis’ account, is connected with the syntactic view of theories, is committed to a logical characterisation of functional roles, and is embedded within Nagelian reductionism. The latter adopts a semantic view of theories, spells out functional roles mainly in terms of mathematical roles within the models of theories, and is expressed in terms of the related structuralist approach to reduction. The development of these frameworks has the final goal of advancing functional reductionism, to make it a fully-fledged alternative account for reduction in science. (shrink)

Functionalism is the view that being x is to play the role of x. This paper defends a functionalist account of three-dimensional entities in the context of Wave Function Realism (WFR), that can explain in detail how we can recover three-dimensional entities out of the wavefunction. In particular, the essay advocates for a novel version of WFR in terms of a functional reductionist approach in the style of David Lewis. This account entails reduction of the upper entities to the bottom (...) ones, when the latter behave appropriately. As applied to WFR, it shows how the wavefunction can turn out to be identical to three-dimensional objects, provided certain conditions. The first major goal of the paper is thus to put forward an improved and more rigorous version of WFR, which dissolves several extant issues about the theory, and can serve as a starting point for future literature on the topic. Moreover, the second major goal of the article is to take WFR as a case study to demonstrate the pros of functional reductionism, especially in the form defended here, thereby helping to bring this view back in the philosophy of science debate. The positive upshots of this paper suggest a possible application of functional reductionism also to other contexts. (shrink)

Negli ultimi anni, il richiamo al concetto di emergenza si è fatto sempre più diffuso in molte aree della filosofia e della scienza. Il termine viene usato per riferirsi alla circostanza in cui un sistema (fisico, chimico, biologico, ma anche sociale) manifesta delle proprietà e dei comportamenti che sembrano nuovi rispetto a quelli delle sue parti più semplici. Questo libro si propone di chiarire questo fenomeno, tenendo conto, da un lato, che le discipline coinvolte nel dibattito sono molte, quindi un (...) approccio univoco all'emergenza potrebbe non bastare e, dall'altro, che per comprendere cosa sia l'emergenza è necessario delinearne le relazioni con altre questioni filosofiche di primaria importanza come quelle che coinvolgono la fondamentalità, la complessità e la causalità.

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)

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)

Rom Harré thinks that the Emergence–Reduction debate, conceived as a vertical problem, is partly ill posed. Even if he doesn’t wholly reject the traditional definition of an emergent property as a property of a collection but not of its components, his point is that this definition doesn’t exhaust all the dimensions of emergence. According to Harré there is another kind (or dimension) of emergence, which we may call—somewhat paradoxically—“horizontal emergence”: two properties of a substance are horizontally emergent relative to each (...) other if they cannot be displayed in the same conditions. Contrary to vertical emergence, horizontal emergence is a symmetrical relation. Harré endorses horizontal emergentism. I argue that this position faces a principled difficulty: it makes it impossible to bind different horizontally emergent discourses in an interesting way. Physics and biology for example become “island” discourses, each speaking of a distinct kind of entities. The only way to ensure that two different discourses can relate to the same entity is to reintroduce verticality into the picture. (shrink)

Convincing disputes about explanatory reductionism in the philosophy of biology require a clear and precise understanding of what a reductive explanation in biology is. The central aim of this book is to provide such an account by revealing the features that determine the reductive character of a biological explanation. Chapters I-IV provide the ground, on which I can then, in Chapter V, develop my own account of explanatory reduction in biology: Chapter I reveals the meta-philosophical assumptions that underlie my analysis (...) of reduction, Chapter II introduces the previous debate about reduction in the philosophy of biology by pointing out the most crucial lessons one should learn from this debate, Chapter III critically discusses the two perspectives on explanatory reduction that have been proposed in the philosophy of biology so far, and Chapter IV clarifies in what ways the issue of reduction is entangled with the issue of explanation. In Chapter V I present my own account of explanatory reduction. My main claim is that reductive explanations in the biological sciences possess three main characteristics: they explain the behavior of a biological system S, first, exclusively in terms of factors that are located on a lower level of organization than S, second, by focusing on factors that are internal to S , and third, by describing the genuine parts of S only as “parts in isolation”. This account is ontic because it traces the reductivity of an explanation back to certain relations that exist in the world. (shrink)

This paper proposes a classification of the intertheoretic relations in physics by bringing out the conditions for a relation of reduction which is eliminative, so that a theory reduced in terms of reductionism is superfluous in principle, and by distinguishing such a relation from another one based on comparison, which will be called neighbourhood of theories; the latter is a neighbouring relation between theories and is not able to support claims of eliminative reductionism. In the first part, it will be (...) argued that this differentiation between neighbourhood and eliminative reduction permits an adequate classification of the intertheoretic relations in physics. By means of this differentiation, the second part discusses reductionism and shows that there are indeed some historical examples of reduction in the aforementioned sense, but that modern physical theories are typically only neighbouring.

The paper sets forth an argument against Kim's distinction between levels and orders.

An entry on the meaning and history of emergence as well as the current debate on emergentism in philosophy and the sciences.

This paper offers a critical assessment of the current state of the debate about the identity and individuality of material objects. Its main aim, in particular, is to show that, in a sense to be carefully specified, the opposition between the Leibnizian ‘reductionist’ tradition, based on discernibility, and the sort of ‘primitivism’ that denies that facts of identity and individuality must be analysable has become outdated. In particular, it is argued that—contrary to a widespread consensus—‘naturalised’ metaphysics supports both the acceptability (...) of non-qualitatively grounded (both ‘contextual’ and intrinsic) identity and a pluralistic approach to individuality and individuation. A case study is offered that focuses on non-relativistic quantum mechanics, in the context of which primitivism about identity and individuality, rather than being regarded as unscientific, is on the contrary suggested to be preferable to the complicated forms of reductionism that have recently been proposed. More generally, by assuming a plausible form of anti-reductionism about scientific theories and domains, it is claimed that science can be regarded as compatible with, or even as suggesting, the existence of a series of equally plausible grades of individuality. The kind of individuality that prevails in a certain context and at a given level can be ascertained only on the basis of the specific scientific theory at hand. (shrink)

In this paper I argue that it is finally time to move beyond the Nagelian framework and to break new ground in thinking about epistemic reduction in biology. I will do so, not by simply repeating all the old objections that have been raised against Ernest Nagel’s classical model of theory reduction. Rather, I grant that a proponent of Nagel’s approach can handle several of these problems but that, nevertheless, Nagel’s general way of thinking about epistemic reduction in terms of (...) theories and their logical relations is entirely inadequate with respect to what is going on in actual biological research practice.

Der Aufsatz lotet den zeitgenössischen Reduktionismus aus. Im ersten Teil wird in zentrale Stationen der wissenschaftstheoretischen Debatte um Theorien-Reduktion eingeleitet, wobei das Schaffner-Hooker-Modell und die Bedeutung von Näherungsbegriffen hervorgehoben werden. Der zweite Teil behandelt die multiple Realisierbarkeit als eines der nach wie vor zentralen anti-reduktionistischen Argumente. Die Analyse soll zeigen, dass es sich hierbei nicht um ein einheitliches Phänomen handelt, sondern dass sehr verschiedene Kategorien von Multirealisierbarkeit zu unterscheiden sind. In einem vereinfachten Slogan: multiple Realisierbarkeit ist ihrerseits multirealisiert. Der Aufsatz (...) entwickelt eine rohe Taxonomie von Typen multipler Realisierbarkeit und möglicher reduktionistischer Strategien, wobei genuine Fälle von Multirealisierbarkeit auf geteilte Eigenschaften zurückgeführt werden. Im letzten Teil wird die besondere Rolle von Näherungen im Zusammenhang mit der explanatorischen Spannung zwischen ontischem Reduktionismus und epistemischen Anti-Reduktionismus verdeutlicht.

Gavagai! or the Future History of the Animal Language Controversy By DAVID PREMACK.

In several places, John Bickle claims that current neuroscientific practice provides actual cellular/molecular reductions of certain mental states. He gives the case study of ‘memory consolidation switch’ as an example where recent findings suggest that this mental state/process can be reduced to the molecular ‘cAMP, PKA, CREB Pathway’. Taking this example, Bickle ‘waves the eleminativist flag’ by claiming that psychological explanations loose their pertinence (or, as he says, ‘became otiose’) once a cellular/molecular explanation replaces them. On this paper I’ll try (...) to show that, even if a reductive explanation of ‘memory consolidation switch’ is disposable, we cannot eschew reductively its causal/functional integrity, i.e.: the explanatory/causal context that defines the mental concept/process ‘memory consolidation switch’ in the first place.

There is a strong philosophical intuition that direct study of the brain can and will constrain the development of psychological theory. When this intuition is tested against case studies on the neurophysiology and psychology of perception and memory, it turns out that psychology has led the way toward knowledge of neurophysiology. An abstract argument is developed to show that psychology can and must lead the way in neuroscientific study of mental function. The opposing intuition is based on mainly weak arguments (...) about the fundamentality or objectivity of physics or physiology in relation to psychology. -/- Philosophy of Science, Vol. 67, Supplement.

This is a first tentative examination of the possibility of reinstating reduction as a valid candidate for presenting relations between mental and physical properties. Classical Nagelian reduction is undoubtedly contaminated in many ways, but here I investigate the possibility of adapting to problems concerning mental properties an alternative definition for theory reduction in philosophy of science. The definition I offer is formulated with the aid of non-monotonic logic, which I suspect might be a very interesting realm for testing notions concerning (...) localized mental-physical reduction. The reason for this is that non-monotonic reasoning by definition is about appeals made not only to explicit observations, but also to an implicit selection of background knowledge containing heuristic information. The flexibility of this definition and the fact that it is not absolute, i.e. that the relation of reduction may be retracted or allowed to shift without fuss, add at least an interesting alternative factor to current materialist debates.

Explanation is a human activity. Teleological, causal, and evolutionary explanations are all valid forms of responding to particular puzzlements. Reductionism incorrectly assumes there is one absolute explanation. While causal explanation appeals primarily to necessity, evolutionary explanation is based largely on contingency.

Super-Humeans argue that the most parsimonious ontology of the natural world compatible with our best physical theories consists exclusively of particles and the distance relations between them. This paper argues by contrast that Super-Humean reduction goes insufficiently far, by showing there to be a more parsimonious ontology compatible with physics: Ultimate-Humeanism. This novel view posits an ontology consisting solely of the particles and distance relations required for the existence of a single brain. Super-Humeans impose conditions on what counts as an (...) ontology of the natural world to avoid their view slipping into this kind of ontology, but these conditions are arbitrarily imposed and once this is exposed, Super-Humeans face a dilemma. Either they can embrace Ultimate-Humeanism as the minimal ontology of the natural world compatible with physics, or (more likely) they can rethink the methodology that got them there. Overall, this paper argues that Super-Humeanism currently lacks principled motivation, outlines a framework for naturalistic ontological reductions, and exposes the consequences of unchecked adherence to a simplicity-driven methodology.

Some arguments against the assumption that ordinary people may share common knowledge are sound. The apparent cost of such arguments is the rejection of scientific theories that appeal to common knowledge. My proposal is to accept the arguments without rejecting the theories. On my proposal, common knowledge is shared by ideally rational people, who are not just mathematically simple versions of ordinary people. They are qualitatively different from us, and theorizing about them does not lead to predictions about our behavior. (...) Nevertheless, models of action that assume common knowledge have a role to play in our understanding of collective rationality. (shrink)

The potential reducibility of chemical entities to their physical bases is a matter of dispute between ontological reductionists on one hand, and emergentists on the other. However, relevant debates typically revolve around the reducibility of so-called ‘higher-level’ chemical entities, such as molecules. Perhaps surprisingly, even committed proponents of emergence for these higher-level chemical entities appear to accept that the ‘lowest-level’ chemical entities – atomic species – are reducible to their physical bases. In particular, the microstructural view of chemical elements, actively (...) developed and defended by emergentists, appears to hold that the explanatory power of nuclear charge justifies being reductionist about atomic species. My first task in this paper is to establish that nuclear charge cannot ultimately provide explanations sufficient to justify a reductionist approach to atomic species, unless we abandon the persuasive intuition that the presence of an element in a substance ought to explain the properties of that substance. The ‘missing piece’ for explaining the properties of substances by way of their elemental constituents is the electronegativity values of participant atoms. But electronegativity is a strikingly disunified concept that appears distinctly unamenable to analysis by way of fundamental physical principles. Through evaluating the uncertain physical identity of electronegativity, as well as its widespread and indispensable epistemic utility in chemical practice, I argue that electronegativity provides compelling grounds to seriously consider emergence for atomic species.

Different forms and transformations of philosophy in the modern world are analyzed according to the view of the Croatian philosopher Vanja Sutlić (1925-1989). A key aspect is the "realization of philosophy" in "work science", which encompasses the entire "world of work" established in modern times. This universal and real science is also an important precondition for "historical thinking". The uniformity of this science, problematized by Sutlić, can be found today in refined logical and semantic structures, which allow for a renewed (...) and richer articulation of philosophical concepts than was traditionally possible.

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.

According to epistemic reductionism about practical reasons, facts about practical reasons can be reduced to facts about evidence for ought-judgements. We argue that this view misconstrues practical conflicts. At least some conflicts between practical reasons put us in a position to know that an action ϕ is optional, i.e. that we neither ought to perform nor ought to refrain from performing the action. By understanding conflicts of practical reasons as conflicts of evidence about what one ought to do, epistemic reductionism (...) fails to account for this. In conflict cases in which ϕ-ing is optional, epistemic reductionism suggests that we have equally strong evidence for and against assuming that we ought to ϕ, and thus cannot be in a position to know that it is not the case that we ought to ϕ. This is a serious flaw. (shrink)

RésuméJe soutiendrai que la façon dont Davidson rend compte de l'intention pure peut être comprise comme une analyse de l'intention comme étant relative à un jugement dans une perspective en première personne. Selon Davidson, avoir la pure intention de faire A, c'est formuler un jugement tout bien considéré qu'il est désirable de faire A. Dans cette analyse anti-réductionniste, l'intention est traitée comme un état irréductible du sujet. J’établirai une comparaison entre cette analyse et celle de Wright et je montrerai comment (...) la position de Davidson peut être considérée comme une analyse non-réductionniste rapportant l'intention au jugement, selon les directions suggérées par Wright. J'expliquerai ensuite comment cette analyse peut aider à éclaircir diverses difficultés qui se présentent dans la conception que Davidson se fait ultérieurement de la signification et du contenu mental.

Some revisionary ontologies are highly parsimonious: they posit far fewer entities than what we quantify over in ordinary discourse. The most radical examples are minimal ontologies, on which physical simples are the only things that exist. Highly parsimonious ontologies, and especially minimal ones, face the challenge of either accounting for the truth of our ordinary quantificational discourse, or paraphrasing such discourse away. Common strategies for addressing this challenge include classical reduction, paraphrase nihilism, and a distinction between ontological and existence commitments. (...) I argue, however, that these strategies are either implausible or fail to provide truth conditions consistent with minimal or parsimonious ontologies. I then discuss, defend, and suggest ways to strengthen an alternative framework for reduction, on which the sentences of reducing theories ground those of reducible theories. Relative to the other options for defending minimal ontology, a strengthened grounding-reductive approach can provide more defensible truth conditions for minimal ontology, better preserve scientific realist intuitions, set a more attainable standard for reduction, and allow our existence commitments to be more responsive to empirical evidence and scientific expertise. As a result, I argue that minimal ontology becomes more defensible—though not certain—on a grounding-reductive framework. But even if minimal ontology were wrong, the grounding-reductive framework makes other parsimonious but non-minimal ontologies more plausible. (shrink)

The main idea of this thesis is multi-descriptional physicalism. According to it, only physical entities are elements of our ontology, and there are different ways to describe them. Higher-level vocabularies (e.g., mental, neurological, biological) truly describe reality. Sentences about higher-level entities are made true by physical entities. Every chapter will develop multi-descriptional physicalism or defend it from objections. In chapter 1, I will propose a new conceptual reductive account that conceptually reduces higher-level entities to physical entities. This conceptual reductive account (...) combines resources from Heil’s truthmaker theory and either a priori physicalism or a posteriori physicalism. In chapter 2, I apply this conceptual reductive account to various debates. Physicalism, the multiple-realisability argument, the prototype theory of concepts, and truthmaker explanations will be discussed. In chapter 3, I will argue that a major aim of metaphysics should be to discover which entities are fundamental and explain why they suffice for the existence of derivative entities. In chapter 4, I will propose a new way to explain why sentences apparently about composite objects are true even though there are no composite objects. It combines resources from Cameron’s truthmaker theory and van Inwagen’s paraphrase strategy. In chapter 5, I will argue that the intuition that the mind and the body are very different does not show that the mind is distinct from the body. This intuition can be explained away by mentioning our dispositions to give non-physical explanations when we are ignorant of physical facts. In chapter 6, I will examine two arguments for the existence of a metaphysically independent level, and I will argue that only a modified version of one of them succeeds. I will argue that methodological principles support the view that there is a metaphysically independent level. (shrink)

The aim of this expository paper is to give an informal overview of a plausible naturalistic case for free will. I will describe what I take to be the main naturalistically motivated challenges for free will and respond to them by presenting an indispensability argument for free will.

I will also explain why the resulting picture of free will does not conflict with the possibility that the fundamental (...) laws of nature are deterministic, and I will address some common objections.

En este artículo se plantea una reconsideración de la elección del reduccionismo de Parfit en Razones y personas como la posición que mejor explica el vínculo de dos sucesos mentales separados en el tiempo. Sin embargo, veremos cómo Parfit basa dicha elección en la consideración de la noción de persona como una sustancia, lo que en principio deja fuera cualquier otra perspectiva. El problema aparece cuando éste no considera apropiadamente el origen histórico de la pregunta en Locke, donde la noción (...) de “persona” se caracteriza en función de la “conciencia de sí”, lo que abre la posibilidad de entender dicha noción a partir de su naturaleza modal en vez de sustancial. En esta medida, se verá cómo esta tercera alternativa incluye una explicación de la conciencia de sí que podría considerarse más razonable bajo los propios términos de Parfit. (shrink)

Book review of William Bechtel's book Mental Mechanist. The book outlines a new and original program for the philosophy of cognitive science using an original concept of mechanism as its core idea. Bechtel’s concept of mechanism is intended to allow for a naturalized science of the mind that is continuous with the other sciences. The review goes through all the claims made in the book.

Drawing on a rich pragmatist tradition, this book offers an account of the different kinds of ‘oughts’, or varieties of normativity, that we are subject to contends that there is no conflict between normativity and the world as science describes it. The authors argue that normative claims aim to evaluate, to urge us to do or not do something, and to tell us how a state of affairs ought to be. These claims articulate forms of action-guidance that are different in (...) kind from descriptive claims, with a wholly distinct practical and expressive character. This account suggests that there are no normative facts, and so nothing that needs any troublesome shoehorning into a scientific account of the world. This work explains that nevertheless, normative claims are constrained by the world, and answerable to reason and argumentation, in a way that makes them truth-apt and objective. (shrink)

The causal efficacy of a material system is usually thought to be produced by the law-like actions and interactions of its constituents. Here, a specific system is constructed and explained that produces a cause that cannot be understood in this way, but instead has novel and autonomous efficacy. The construction establishes a proof-of-feasibility of strong emergence. The system works by utilizing randomness in a targeted and cyclical way, and by relying on sustained evolution by natural selection. It is not vulnerable (...) to standard arguments against strong emergence, in particular ones that assume that the physical realm is causally closed. Moreover, it does not suffer from epiphenomenalism or causal overdetermination. The system uses only standard material components and processes, and is fully consistent with naturalism. It is discussed whether the emergent cause can still be viewed as ‘material’ in the way that term is commonly understood. (shrink)

“Dialectic” has been a matter of growing interest in contemporary philosophy. The present article analyzes dialectical methods and positions them by reference to two paradigmatic texts of German idealism and analytic philosophy, i.e. J.G. Fichte’s Science of Knowing (1804) and J. McDowell’s Mind and World. Both dialectical approaches will be interpreted with regard to their contribution in the debate on reductionism and anti-reductionism: both Fichte and McDowell claim that philosophical positions and logical terms stand in a dualistic relationship to one (...) another, on the one hand, but are separated by a gulf, on the other. I will argue that for McDowell dialectic seems to be an alternative to one-sided reductionisms as well as to normal anti-reductionistic holism. Furthermore, for Fichte dialectic is an adequate method for describing the relationship of reductionism and anti-reductionism itself. Both see in dialectic a technique for bridging the gulf between binary opposite terms of logic as well as mutually exclusive positions, such as mind and world, subject and object, or idealism and realism.

Unity of science was once a very popular idea among both philosophers and scientists. But it has fallen out of fashion, largely because of its association with reductionism and the challenge from multiple realisation. Pluralism and the disunity of science are the new norm, and higher-level natural kinds and special science laws are considered to have an important role in scientific practice. What kind of reductionism does multiple realisability challenge? What does it take to reduce one phenomenon to another? How (...) do we determine which kinds are natural? What is the ontological basis of unity? In this Element, Tuomas Tahko examines these questions from a contemporary perspective, after a historical overview. The upshot is that there is still value in the idea of a unity of science. We can combine a modest sense of unity with pluralism and give an ontological analysis of unity in terms of natural kind monism. This title is available as Open Access on Cambridge Core. (shrink)

"Люди говорят снова и снова, что философия на самом деле не прогресс, что мы по-прежнему заняты теми же философскими проблемами, что и греки. Но люди, которые говорят это, не понимают, почему это должно быть так. Это потому, что наш язык остался прежним и продолжает соблазнять нас задавать те же вопросы.

Деннетт, хотя он был философом в течение 40 лет, является одним из них. Любопытно также, что и он, и его главный антагонист Джон Сирл учились у знаменитых Витгенштейнов (Сирл с Джоном Остином, Деннет с Гилбертом Райлом), но Сирл более или менее получил точку, а Деннет т , (хотя это растяжение вещей, чтобы назвать Сирл или Райл Витгенштейнов). Деннетт является жесткий детерминант (хотя он пытается проникнуть реальность в задней двери), и, возможно, это связано с Райл, чья знаменитая книга "Концепция разума" (1949) продолжает быть перепечатаны. Эта книга проделала большую работу по изгнанию призрака, но он покинул машину. Деннетт любит делать ошибки Витгенштейна, Райл (и многие другие с тех пор) разоблачили в деталях. Наше использование слов сознание, выбор, свобода, намерение, частицы, мышление, определяет, волна, причина, произошло, событие (и так далее бесконечно) редко источником путаницы, но как только мы оставляем нормальную жизнь и введите философию (и любое обсуждение отделены от среды, в которой язык развивался-т.е., точный контекст, в котором слова имели смысл)хаос царит. Как и большинству,, Деннетне не хватает когерентной структуры - которую Сирл назвал логической структурой рациональности. Я расширил на этом значительно, так как я написал этот обзор, и мои последние статьи показывают подробно, что случилось с подходом Деннетк к философии, который можно было бы назвать Scientism на стероидах.

Último sermón de la iglesia del naturalismo fundamentalista por el pastor Hofstadter. Al igual que su mucho más famoso (o infame por sus incesantemente errores filosóficos) trabajo Godel, Escher, Bach, tiene una plausibilidad superficial, pero si se entiende que se trata de un científico rampante que mezcla problemas científicos reales con los filosóficos (es decir, el sólo los problemas reales son los juegos de idiomas que debemos jugar) entonces casi todo su interés desaparece. Proporciono un marco para el análisis basado (...) en la psicología evolutiva y el trabajo de Wittgenstein (ya actualizado en mis escritos más recientes). Aquellos que deseen un marco completo hasta la fecha para el comportamiento humano de la moderna dos sistemas punto de vista puede consultar mi libros Talking Monkeys 3ª ed (2019), Estructura Logica de Filosofia, Psicología, Mente y Lenguaje en Ludwig Wittgenstein y John Searle 2ª ed (2019), Suicidio pela Democracia 4ª ed (2019), La Estructura Logica del Comportamiento Humano (2019), The Logical Structure de la Conciencia (2019, Comprender las Conexiones entre Ciencia, Filosofía, Psicología, Religión, Política y Economía, Historia y Literatura (2019), Delirios Utópicos Suicidas en el siglo 21 5ª ed (2019), Observaciones sobre Imposibilidad, Incompletitud, Paraconsistencia, Indecidibilidad, Aleatoriedad, Computabilidad, Paradoja e Incertidumbre en Chaitin, Wittgenstein, Hofstadter, Wolpert, Doria, da Costa, Godel, Searle, Rodych Berto, Floyd, Moyal-Sharrock y Yanofsky(2019) y otros. "Podría ser justamente preguntado qué importancia tiene la prueba de Gödel para nuestro trabajo. Para un pedazo de matemáticas no puede resolver problemas del tipo que nos molesten. --La respuesta es que la situación, en la que tal prueba nos trae, es de interés para nosotros. ' ¿Qué vamos a decir ahora? ' --Ese es nuestro tema. Sin embargo, extraña que suene, mi tarea en lo que concierne a la prueba de Gödel parece meramente consistir en aclarar lo que tal proposición como: "Supongamos que esto se puede demostrar" significa en matemáticas. " Wittgenstein "Comentarios sobre los fundamentos de las matemáticas" p337 (1956) (escrito en 1937). "Mis teoremas sólo muestran que la mecanización de las matemáticas, es decir, la eliminación de la mente y de las entidades abstractas, es imposible, si uno quiere tener una base satisfactoria y un sistema de matemáticas. No he probado que haya preguntas matemáticas que sean indescifrables para la mente humana, pero sólo que no hay máquina (o formalismo ciego) que pueda decidir todas las preguntas de la teoría numérica, (incluso de un tipo muy especial) .... No es la estructura misma de los sistemas deductivos que está siendo amenazado con un descompostura, sino sólo una cierta interpretación de la misma, es decir, su interpretación como un formalismo ciego. " Gödel "Obras Recogidas" VOL 5, p 176-177. (2003) "Toda inferencia tiene lugar a priori. Los acontecimientos del futuro no pueden deducirse de los del presente. La superstición es la creencia en el nexo causal. La libertad de la voluntad consiste en el hecho de que las acciones futuras no se pueden conocer ahora. Sólo podíamos conocerlas si la causalidad fuera una necesidad interna, como la de la deducción lógica. --La conexión del conocimiento y lo que se conoce es la necesidad lógica. ("A sabe que p es el caso" no tiene sentido si p es una tautología.) Si por el hecho de que una proposición es obvia para nosotros, no sigue que es verdad, entonces la evidencia no es ninguna justificación para creer en su verdad. " TLP 5,133--5,1363 . (shrink)

Polger and Shapiro (2016) claim that unlike human-made artifacts cases of multiple realization in naturally occurring systems are uncommon. Drawing on cases from systems biology, I argue that multiple realization in naturally occurring systems is not as uncommon as Polger and Shapiro initially thought. The relevant cases, which I draw from systems biology, involve generalizable design principles called network motifs which recur in different organisms and species and perform specific functions. I show that network motifs with entirely different underlying causal (...) structures can perform the same function of interest. The article also considers the scope problem of multiple realization.

Es mi afirmación que la tabla de intencionalidad (racionalidad, mente, pensamiento, lenguaje, personalidad, etc.) que presenta prominentemente aquí describe más o menos con precisión, o al menos sirve como heurística para, cómo pensamos y nos comportamos, y por lo tanto no abarca simplemente filosofía y psicología, sino todo lo demás (historia, literatura, matemáticas, política, etc.). Tenga en cuenta especialmente que la intencionalidad y racionalidad como yo (junto con Searle, Wittgenstein y otros) lo veo, incluye tanto el Sistema Linguístico deliberativo consciente (...) 2 como las acciones o reflejos inconscientes automatizados del Sistema 1 automatizado. -/- Proporciono una encuesta crítica de algunos de los principales hallazgos de dos de los estudiantes más eminentes del comportamiento de los tiempos modernos, Ludwig Wittgenstein y John Searle, sobre la estructura lógica de la intencionalidad (mente, lenguaje, comportamiento), tomando como punto de partida El descubrimiento fundamental de Wittgenstein -que todos los problemas verdaderamente "filosóficos" son los mismos —confusiones sobre cómo usar el lenguaje en un contexto particular, y por lo tanto todas las soluciones son iguales— mirando cómo se puede utilizar el lenguaje en el contexto en cuestión para que su verdad condiciones (Condiciones de Satisfacción o COS) son claras. El problema básico es que se puede decir cualquier cosa, pero no se puede significar (indicar COS claro para) cualquier expresión arbitraria y significado sólo es posible en un contexto muy específico. Analizo varios escritos por y sobre ellos desde la perspectiva moderna de los dos sistemas de pensamiento (popularizados como 'pensar rápido, pensar lento'), empleando una nueva tabla de intencionalidad y nueva nomenclatura de sistemas duales. Demuestro que esta es una heurística poderosa para describir el comportamiento. -/- Por lo tanto, todo comportamiento está íntimamente conectado si uno toma el punto de vista correcto. La Ilusión Fenomenológica (olvido a nuestro Sistema automatizado 1) es universal y se extiende no sólo a lo largo de la filosofía, sino a lo largo de la vida. Estoy seguro de que Chomsky, Obama, Zuckerberg y el Papa serían incrédulos si se les dijera que sufren del mismo problema que Hegel, Husserl y Heidegger, (o que difieren sólo en grado de los adictos a las drogas y el sexo en estar motivados por la estimulación de su cortices frontales por la entrega de dopamina (y más de 100 otros productos químicos) a través del tegmentum ventral y el núcleo accumbens), pero es claramente cierto. Mientras que los fenomenólogos sólo desperdiciaron mucho el tiempo de la gente, están desperdiciando la tierra y el futuro de sus descendientes. -/- . (shrink)

Reduction and reductionism have been central philosophical topics in analytic philosophy of science for more than six decades. Together they encompass a diversity of issues from metaphysics and epistemology. This article provides an introduction to the topic that illuminates how contemporary epistemological discussions took their shape historically and limns the contours of concrete cases of reduction in specific natural sciences. The unity of science and the impulse to accomplish compositional reduction in accord with a layer-cake vision of the sciences, the (...) seminal contributions of Ernest Nagel on theory reduction and how they strongly conditioned subsequent philosophical discussions, and the detailed issues pertaining to different accounts of reduction that arise in both physical and biological science (e.g., limit-case and part-whole reduction in physics, the difference-making principle in genetics, and mechanisms in molecular biology) are explored. The conclusion argues that the epistemological heterogeneity and patchwork organization of the natural sciences encourages a pluralist stance about reduction. (shrink)

Reductionists say things like: all mental properties are physical properties; all normative properties are natural properties. I argue that the only way to resist reductionism is to deny that causation is difference making (thus making the epistemology of causation a mystery) or to deny that properties are individuated by their causal powers (thus making properties a mystery). That is to say, unless one is happy to deny supervenience, or to trivialize the debate over reductionism. To show this, I argue that (...) if properties are individuated by their causal powers then, surprisingly, properties are individuated by necessary co-exemplification. (shrink)

Flat Physicalism is a theory of through and through type reductive physicalism, understood in light of recent results in the conceptual foundations of physics. In Flat Physicalism, as in physics, so-called "high level" concepts and laws are nothing but partial descriptions of the complete states of affairs of the universe. "Flat physicalism" generalizes this idea, to form a reductive picture in which there is no room for levels, neither explanatory nor ontological. The paper explains how phenomena that seem to be (...) cases of multiple realization of special sciences kinds by physical kinds are fully explains in a reductive physicalist way. Finally, the paper exemplifies the fruitfulness of this reductive approach by showing how it can account even for a case of high-level anomaly in a deterministic universe (for example anomaly of the mental, should this turn our to be a fact about the world) - a result that may be called Anomalous Physicalism.

Biochemical kinds such as proteins pose interesting problems for philosophers of science, as they can be studied from the points of view of both biology and chemistry. The relationship between the biological functions of biochemical kinds and the microstructures that they are related to is the key question. This leads us to a more general discussion about ontological reductionism, microstructuralism, and multiple realization at the biology-chemistry interface. On the face of it, biochemical kinds seem to pose a challenge for ontological (...) reductionism and hence motivate a dual theory of chemical and biological kinds, a type of pluralism about natural kinds. But it will be argued that the challenge, which is based on multiple realization, can be addressed. The upshot is that there are reasonable prospects for ontological reductionism about biochemical kinds, which corroborates natural kind monism. (shrink)

Each thing is fundamental. Not only is no thing any more or less real than any other, but no thing is prior to another in any robust ontological sense. Thus, no thing can explain the very existence of another, nor account for how another is what it is. I reach this surprising conclusion by undermining two important positions in contemporary metaphysics: hylomorphism and hierarchical views employing so-called building relations, such as grounding. The paper has three main parts. First, I observe (...) hylomorphism is alleged by its proponents to solve various philosophical problems. However, I demonstrate, in light of a compelling account of explanation, that these problems are actually demands to explain what cannot be but inexplicable. Second, I show how my argument against hylomorphism illuminates an account of the essence of a thing, thereby providing insight into what it is to exist. This indicates what a thing, in the most general sense, must be and a correlative account of the structure in reality. Third, I argue that this account of structure is incompatible not only with hylomorphism, but also with any hierarchical view of reality. Although hylomorphism and the latter views are quite different, representing distinct philosophical traditions, I maintain they share untenable accounts of structure and fundamentality and so should be rejected on the same grounds.

Ethical reductionism is the best version of naturalistic moral realism. Reductionists regard moral properties as identical to properties appearing in successful scientific theories. Nonreductionists, including many of the Cornell Realists, argue that moral properties instead supervene on scientific properties without identity. I respond to two arguments for nonreductionism. First, nonreductionists argue that the multiple realizability of moral properties defeats reductionism. Multiple realizability can be addressed in ethics by identifying moral properties uniquely or disjunctively with properties of the special sciences. Second, (...) nonreductionists argue that irreducible moral properties explain empirical phenomena, just as irreducible special-science properties do. But since irreducible moral properties don't successfully explain additional regularities, they run the risk of being pseudoscientific properties. Reductionism has all the benefits of nonreductionism, while also being more secure against anti-realist objections because of its ontological simplicity. (shrink)
