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

The general aim of this paper is to propose a reductionist strategy to higher-level property types. Starting from a common ground in the philosophy of science, I shall elaborate on possible realizer differences of higher-level property types. Because of the realizer types' causal heterogeneity, an introduction of functional sub-types of higher-level properties will be suggested. Each higher-level functional sub-type corresponds to one realizer type. This means that there is the theoretical possibility to reach some kind of type-identity and this opens (...) up the way for theory reduction in a more complete manner. This kind of type-identity will go beyond the common ground of the identity of tokens and their reductive explanation. In the second part of the paper, this reductionist strategy will be applied to a specific debate in the philosophy of biology — the reductionist approach to classical genetics from a molecular point of view.

_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.

One of the main issues in philosophy is the refl ection on sciences. In order to conciliate the unity and plurality of sciences, this paper sets out a new strategy for theory reduction by means of functional sub-concepts. This strategy is intended to get around the multiple realization objection that leads to a dilemma for the scientifi c quality of the special sciences. Taking Kim’s argument for token identity as starting point, I shall show a strategy to establish a systematic (...) link between concepts of the special sciences with physical concepts. By this means, a conservative theory reduction is in principle possible despite multiple realization. (shrink)

Cet ouvrage proposé un panorama complet des débats contemporains en philosophie de la biologie. Il consacre une large place à la représentation des principes fondateurs de la théorie de l'évolution et des principaux concepts et lois génétiques, ainsi qu'à l'examen des questions posées par la sélection naturelle comme par la notion de fitness et l'unité de sélection. L'auteur discute en ces pages la définition du vivant et la potion de fonction biologique, et développe notamment une conception causale et mécaniste des (...) processus biologiques dans une perspective réductionniste originale. Clair et didactique, cet ouvrage résume systématiquement l'état actuel des connaissances, présente les différents concepts et positions, propose une évaluation des résultats et montre que les questions ouvertes dépasse largement le seul cadre de la biologie. Il vise ainsi à contribuer au développement d'une philosophie de la biologie nouvelle, en lien étroit avec la philosophie des sciences dans son ensemble. (shrink)

In his work, Horgan argues for the compatibilism of agency, mental state-causation, and physical causal-closure. We generally assume a causally closed physical world that seems to exclude agency in the sense of mental state-causation in addition to physical causation. However, Horgan argues for an account of agency that satisfies the experience of our own as acting persons and that is compatible with physical causal-closure. Mental properties are causal properties but not identical with physical properties because there are different ontological levels. (...) In this commentary, I shall reconsider the essential issues of this compatibilism (1), focus on a problem for Horgan’s conception of agent causation that arises from the causal argument for ontological reductionism (2), and propose to embed Horgan’s conception of agency within a reductionist approach in order to vindicate the indispensable character of agency (3).

The paper sets out a new strategy for theory reduction by means of functional sub-types. This strategy is intended to get around the multiple realization objection. We use Kim's argument for token identity (ontological reductionism) based on the causal exclusion problem as starting point. We then extend ontological reductionism to epistemological reductionism (theory reduction). We show how one can distinguish within any functional type between functional sub-types. Each of these sub-types is coextensive with one type of realizer. By this means, (...) a conservative theory reduction is in principle possible, despite multiple realization. We link this account with Nagelian reduction, as well as with Kim's functional reduction. (shrink)

The paper argues that a functional reduction of ordinary psychology to neuropsychology is possible by means of constructing fine-grained functional, mental sub-types that are coextensive with neuropsychological types. We establish this claim by means of considering as examples the cases of the disconnection syndrome and schizophrenia. We point out that the result is a conservative reduction, vindicating the scientific quality of the mental types of ordinary psychology by systematically linking them with neuroscience. That procedure of conservative reduction by means of (...) functional sub-types is in principle repeatable down to molecular neuroscience. (shrink)

This paper points out the merit of Nagelian reduction, namely to propose a model of inter-theoretic reduction that retains the scientific quality of the reduced theory and the merit of functional reduction, namely to take multiple realization into account and to offer reductive explanations. By considering Lewis and Kim’s proposal for local reductions, we establish that functional reduction fails to achieve a theory reduction and cannot retain the scientific quality of the reduced theory. We improve on that proposal by showing (...) how one can build functional sub-types that are coextensive with physical realizer types and thereby obtain a theory reduction that is explanatory and that vindicates the scientific quality of the special sciences.

This paper summarizes (in German) recent tendencies in the philosophy of the life sciences.

According to physicalism, everything is physical or metaphysically connected to the physical. If physicalism were true, it seems that we should – in principle – be able to reduce the descriptions and explanations of special sciences to physical ones, for example, explaining biological regularities, via chemistry, by the laws of particle physics. The multiple realization of the property types of the special sciences is often seen to be an obstacle to such epistemic reductions. Here, we introduce another, new argument against (...) epistemic reduction. Based on mathematical complexity, we show that, under certain conditions, there can be “complexity barriers” that make epistemic reduction – in principle – unachievable even if physicalism were true.

Reductionism in the Philosophy of Science develops a novel account of reduction in science and applies it to the relationship between classical and molecular genetics. However, rather than addressing the epistemological issues that have been essential to the reductionism debate in philosophy of biology, the discussion primarily pursues ontological questions, as they are known, about reducing the mental to the physical. For Sachse construes reductionism as a purely philosophical endeavor and defends the possibility of reduction in principle, which may (...) not be relevant to understanding reductionist reasoning and explanation occurring in scientific practice, as discussed by philosophers of science. Likewise, the conceptual framework used stems more from metaphysics and philosophy of mind than philosophy of science. Sachse's aim is twofold. First, he argues for the special sciences' being reducible to physics, by deriving the in principle possibility of epistemological reduction from ontological reduction. Second, he attempts to simultaneously make room for the legitimacy of the special sciences, effecting a conservative reduction rather than an elimination of the special sciences. (shrink)

El concepto de fraternidad en la Doctrina Social de la Iglesia entiende la naturaleza humana en términos relacionales. Los deberes fraternos son consustanciales a la naturaleza humana y por tanto el conflicto entre libertad e igualdad queda atenuado. En el contexto de la economía globalizada, la fraternidad, vinculada al principio de gratuidad y a la lógica del don, se propone como vía para lograr una humanización de una economía que amenaza con independizarse del control político. En términos católicos, esta fraternidad (...) se acoge al principio de subsidiariedad. Frente a las concepciones contractualistas de la fraternidad que parten del conflicto, la fraternidad católica mantiene una antropología relacional que naturaliza la motivación para el ejercicio de los deberes fraternos.

The present study describes the mechanism of need regulation, which accompanies the so-called “biased” decisions. We hypothesized an unconscious urge for psychological need satisfaction as the trigger for cognitive biases. In an experimental study (N = 106), participants had the opportunity to win money in a functionality test. In the test, they could either use the solution they had developed (sunk cost) or an alternative solution that offered a higher probability of winning. The selection of the sunk-cost option was the (...) most chosen option, supporting the hypothesis of this study. The reason behind the majority of participants choosing the sunk-cost option seemed to be the satisfaction of psychological needs, despite a reduced chance of winning money. An intervention, which aimed at triggering self-reflection, had no impact on the decision. The findings of this study contribute to the discussion on the reasons for cognitive biases and their formation in the human mind. Moreover, it discusses the application of the label “irrational” for biased decisions and proposes reasons for instrumental rationality, which exist at an unconscious, need-regulative level.

This paper maps out various options for thinking about two issues: the structural relationship between practical wisdom and the moral virtues, and the various functions of practical wisdom. With the help of a case study of the virtue of honesty, three main concerns are raised for what I call the Standard Model of practical wisdom. Two other models, the Socratic Model and the Fragmentation Model, are also critically evaluated. I end by taking seriously an eliminativist approach according to which the (...) trait of practical wisdom does not exist. (shrink)

Humean Laws for Human Agents presents cutting-edge research by leading experts on the Humean account of laws, chance, possibility, and necessity. A central question in metaphysics and philosophy of science is: What are laws of nature? Humeans hold that laws are not sui generis metaphysical entities but merely particularly effective summaries of what actually happens. The most discussed recent work on Humeanism emphasizes the laws' usefulness for limited agents and uses pragmatic considerations to address fundamental and long-standing problems. The current (...) volume develops and critically examines pragmatic Humean accounts, with innovative new work on the epistemology of laws and chance, the problem of induction, counterfactuals, special science laws, and a Humean account of essence. Taken together, the papers provide a roadmap for developing pragmatic Humeanism and connate views, setting the agenda for future research. (shrink)

This article examines the methodology of a core branch of contemporary political theory or philosophy: “analytic” political theory. After distinguishing political theory from related fields, such as political science, moral philosophy, and legal theory, the article discusses the analysis of political concepts. It then turns to the notions of principles and theories, as distinct from concepts, and reviews the methods of assessing such principles and theories, for the purpose of justifying or criticizing them. Finally, it looks at a recent debate (...) on how abstract and idealized political theory should be, and assesses the significance of disagreement in political theory. The discussion is carried out from an angle inspired by the philosophy of science. (shrink)

Most people who are regular consumers of psychoactive drugs are not drug addicts, nor will they ever become addicts. In neurobiological theories, non-addictive drug consumption is acknowledged only as a “necessary” prerequisite for addiction, but not as a stable and widespread behavior in its own right. This target article proposes a new neurobiological framework theory for non-addictive psychoactive drug consumption, introducing the concept of “drug instrumentalization.” Psychoactive drugs are consumed for their effects on mental states. Humans are able to learn (...) that mental states can be changed on purpose by drugs, in order to facilitate other, non-drug-related behaviors. We discuss specific “instrumentalization goals” and outline neurobiological mechanisms of how major classes of psychoactive drugs change mental states and serve non-drug-related behaviors. We argue that drug instrumentalization behavior may provide a functional adaptation to modern environments based on a historical selection for learning mechanisms that allow the dynamic modification of consummatory behavior. It is assumed that in order to effectively instrumentalize psychoactive drugs, the establishment of and retrieval from a drug memory is required. Here, we propose a new classification of different drug memory subtypes and discuss how they interact during drug instrumentalization learning and retrieval. Understanding the everyday utility and the learning mechanisms of non-addictive psychotropic drug use may help to prevent abuse and the transition to drug addiction in the future. (shrink)

A pioneer in the field, Christian Metz applies insights of structural linguistics to the language of film. "The semiology of film . . . can be held to date from the publication in 1964 of the famous essay by Christian Metz, 'Le cinema: langue ou langage?'"--Geoffrey Nowell-Smith, Times Literary Supplement "Modern film theory begins with Metz."--Constance Penley, coeditor of Camera Obscura "Any consideration of semiology in relation to the particular field signifying practice of film passes inevitably through a (...) reference to the work of Christian Metz. . . .

"Man ist nicht umsonst Philologe gewesen, man ist es vielleicht noch" - Nietzsches Bekenntnisse zur Philologie sind zahlreich. Auf der Grundlage von Quellenstudien beschreibt die Abhandlung Nietzsches tiefe Prägung durch die historisch-kritische Methode der Bonner Schule. Um Philosoph zu werden, musste er sich nicht, wie bisher angenommen, von der Philologie lösen, sondern sprach ihr gerade im Spätwerk eine zentrale Rolle zu. Diese Einsicht führt zur Neubestimmung von Begriffen wie Text, Genealogie, Interpretation, Perspektivismus und zur Zurückweisung herrschender Auffassungen der Wissenschaftsgeschichte, der (...) Hermeneutik und des Dekonstruktivismus. Die Studie endet mit einem von Nietzsche ausgehenden, historisch begründeten Plädoyer für die skeptisch-philologische Literaturwissenschaft. (shrink)

This collection provides the first in-depth introduction to the theory of the religious imagination put forward by renowned philosopher Douglas Hedley, from his earliest essays to his principal writings. Featuring Hedley's inaugural lecture delivered at Cambridge University in 2018, the book sheds light on his robust concept of religious imagination as the chief power of the soul's knowledge of the Divine and reveals its importance in contemporary metaphysics, ethics and politics. Chapters trace the development of the religious imagination in (...) class='Hi'>Christian Platonism from Late Antiquity to British Romanticism, drawing on Origen, Henry More and Samuel Taylor Coleridge, before providing a survey of alternative contemporary versions of the concept as outlined by Karl Rahner, René Girard and William P. Alston, as well as within Indian philosophy. By bringing Christian Platonist thought into dialogue with contemporary philosophy and theology, the volume systematically reveals the relevance of Hedley's work to current debates in religious epistemology and metaphysics. It offers a comprehensive appraisal of the historical contribution of imagination to religious understanding and, as such, will be of great interest to philosophers, theologians and historians alike.

I first summarize the main line of argument used by Harman and Doris against Aristotelian virtue ethics in particular. In section two I present what seems to me to be the most promising response to their argument. Finally in section three I briefly review and assess the other leading responses in the now sizable literature that has developed in this area.
