In this paper I examine Jaegwon Kim’s view that emergent properties are irreducible to the base properties on which they supervene. Kim’s view assumes a model of ‘functional reduction’ which he claims to be substantially different from the traditional Nagelian model. I dispute this claim and argue that the two models are only superficially different, and that on either model, properly understood, it is possible to draw a distinction between a property’s being reductively identifiable with its base property and a (...) property’s being reductively explainable in terms of it. I propose that we should take as the distinguishing feature of emergent properties that they be truly novel properties, i.e., ontologically distinct from the ‘base’ properties which they supervene on. This only requires that emergent properties cannot be reductively identified with their base properties, not that they cannot be reductively explained in terms of them. On this conception the set of emergent properties may well include mental properties as conceived by nonreductive physicalists. (shrink)

Relationships between current theories, and relationships between current theories and the sought theory of quantum gravity (QG), play an essential role in motivating the need for QG, aiding the search for QG, and defining what would count as QG. Correspondence is the broad class of inter-theory relationships intended to demonstrate the necessary compatibility of two theories whose domains of validity overlap, in the overlap regions. The variety of roles that correspondence plays in the search for QG are illustrated, using examples (...) from specific QG approaches. Reduction is argued to be a special case of correspondence, and to form part of the definition of QG. Finally, the appropriate account of emergence in the context of QG is presented, and compared to conceptions of emergence in the broader philosophy literature. It is argued that, while emergence is likely to hold between QG and general relativity, emergence is not part of the definition of QG, and nor can it serve usefully in the development and justification of the new theory.

In this paper I discuss the claim that the successful reduction of qualitative to physical states requires some sort of intelligible connection between our qualitative and physical concepts, which in turn requires a conceptual analysis of our qualitative concepts in causal-functional terms. While I defend this claim against some of its recent critics, I ultimately dispute it, and propose a different way to get the requisite intelligible connection between qualitative and physical concepts.

Sabina Alkire shows how Nobel Prize-winning economist Amartya Sen's capability approach can be coherently---and practically---put to work in poverty reduction activities so that the voices and values of the poor matter. This provides economists, philosophers, theologians, and development practitioners with a way forward that addresses both theoretical and practical challenges.

I critically evaluate Bickle’s version of scientific theory reduction. I press three main points. First, a small point, Bickle modifies the new wave account of reduction developed by Paul Churchland and Clifford Hooker by treating theories as set-theoretic structures. But that structuralist gloss seems to lose what was distinctive about the Churchland-Hooker account, namely, that a corrected theory must be specified entirely by terms and concepts drawn from the basic reducing theory. Set-theoretic structures are not terms or concepts but the (...) structures that they describe. Second, and more serious, a familiar problem for classical positivist account of reduction resurfaces within this newest wave of thinking, namely, commitment to property identities and inter-theoretic bridge laws (a problem I discussed at more length in "Collapse of the New Wave"). Indeed, this problem is exacerbated by Bickle’s conciliatory treatment of property plasticity, since he is willing to grant that a large number of special science terms denote multiply realized properties, at least if realistically construed. Still, in the end, Bickle sidesteps the reduction of properties by appealing to Hooker’s "function-to-structure token reduction." This is an interesting move with an intriguing concept of reduction. But problems remain. For, third, Bickle and Hooker's function-to-structure token reduction is actually a guised form of eliminative materialism. But that should be unacceptable since the position extends well beyond any modest revisionism for suspect items from a folk theory, say, in folk psychology or folk biology. Instead, it applies to functional terms and concepts employed throughout well-developed and explanatorily successful sciences. (shrink)

We study logical reduction (factorization) of relations into relations of lower arity by Boolean or relative products that come from applying conjunctions and existential quantifiers to predicates, i.e. by primitive positive formulas of predicate calculus. Our algebraic framework unifies natural joins and data dependencies of database theory and relational algebra of clone theory with the bond algebra of C.S. Peirce. We also offer new constructions of reductions, systematically study irreducible relations and reductions to them and introduce a new characteristic of (...) relations, ternarity, that measures their ‘complexity of relating’ and allows to refine reduction results. In particular, we refine Peirce’s controversial reduction thesis, and show that reducibility behaviour is dramatically different on finite and infinite domains. (shrink)

Twentieth Century philosophical thought has expressed itself for the most part through two great Movements: the phenomenological and the analytical. Each movement originated in reaction against idealistic—or at least antirealistic—views of "the world". And each has collapsed back into an idealism not different in effect from that which it initially rejected. Both movements began with an appeal to meanings or concepts, regarded as objective realities capable of entering the flow of experience without loss of their objective status or of their (...) power to reveal to us an objective world as it would be if there were no subjective apprehensions of it. Both movements ended with a surrender of the objectivity of meanings and concepts in this strong sense, coming to treat them as at most more-or-less shareable components of a somehow communalized experience, but in any case incapable of revealing how things are irrespective of actual human experience. For the old Egocentric Predicament, with its "ideas" etc., is substituted a Lingocentric or Histrocentric Predicament of "language" and its elements. Hilary Putnam speaks for the current consensus: 'Internal realism says that we don't know what we are talking about when we talk about "things in themselves"' ( The Many Faces of Realism , p. 36).

In a recent article, Fabrice Correia explores the project of reducing the notion of grounding to that of essence. He then goes on to provide several candidate definitions and test each of them against a number of objections. His final take on the situation is, roughly, that two of the definitions can handle all of the considered objections. The aim of this paper is to re-evaluate Correia's conclusions in the light of two sources of insights: Firstly, I will argue that (...) one of the objections treated by Correia has been somewhat underestimated, and that it still constitutes a threat against definitions of grounding in terms of essence. Secondly, there are at least two further objections that should be considered by the advocate of such definitions. As I will show, one of them can be neutralized; but the other one is more serious and suggests a clear dialectical edge to an operationalist definition. (shrink)

This is a companion to another paper. Together they rebut two widespread philosophical doctrines about emergence. The first, and main, doctrine is that emergence is incompatible with reduction. The second is that emergence is supervenience; or more exactly, supervenience without reduction.In the other paper, I develop these rebuttals in general terms, emphasising the second rebuttal. Here I discuss the situation in physics, emphasising the first rebuttal. I focus on limiting relations between theories and illustrate my claims with four examples, each (...) of them a model or a framework for modelling, from well-established mathematics or physics.I take emergence as behaviour that is novel and robust relative to some comparison class. I take reduction as, essentially, deduction. The main idea of my first rebuttal will be to perform the deduction after taking a limit of some parameter. Thus my first main claim will be that in my four examples (and many others), we can deduce a novel and robust behaviour, by taking the limit N→∞ of a parameter N.But on the other hand, this does not show that the N=∞ limit is “physically real”, as some authors have alleged. For my second main claim is that in these same examples, there is a weaker, yet still vivid, novel and robust behaviour that occurs before we get to the limit, i.e. for finite N. And it is this weaker behaviour which is physically real.My examples are: the method of arbitrary functions (in probability theory); fractals (in geometry); superselection for infinite systems (in quantum theory); and phase transitions for infinite systems (in statistical mechanics).

Reductionism is a central issue in the philosophy of biology. One common objection to reduction is that molecular explanation requires reference to higher-level properties, which I refer to as the context objection. I respond to this objection by arguing that a well-articulated notion of a mechanism and what I term mechanism extension enables one to accommodate the context-dependence of biological processes within a reductive explanation. The existence of emergent features in the context could be raised as an objection to the (...) possibility of reduction via this strategy. I argue that this objection can be overcome by showing that there is no tenable argument for the existence of emergent properties that are not susceptible to a reductive explanation. (shrink)

We study how to postpone the application of the reductio ad absurdum rule (RAA) in classical natural deduction. This technique is connected with two normalization strategies for classical logic, due to Prawitz and Seldin, respectively. We introduce a variant of Seldin’s strategy for the postponement of RAA, which induces a negative translation from classical to intuitionistic and minimal logic. Through this translation, Glivenko’s theorem from classical to intuitionistic and minimal logic is proven.

Harm-reduction approaches are used to reduce the burden of risky human behaviour without necessarily aiming to stop the behaviour. We discuss what an introduction of harm reduction for doping in sports would mean in parallel with a relaxation of the antidoping rule. We analyse what is ethically at stake in the following five levels: (1) What would it mean for the athlete (the self)? (2) How would it impact other athletes (the other)? (3) How would it affect the phenomenon of (...) sport as a game and its fair play basis (the play)? (4) What would be the consequences for the spectator and the role of sports in society (the display)? and (5) What would it mean for what some consider as essential to being human (humanity)? For each level, we present arguments for and against doping and then discuss what a harm-reduction approach, within a dynamic regime of a partially relaxed antidoping rule, could imply. We find that a harm-reduction approach is morally defensible and potentially provides a viable escape out of the impasse resulting from the impossibility of attaining the eradication of doping. The following question remains to be answered: Would a more relaxed position, when combined with harm-reduction measures, indeed have less negative consequences for society than today9s all-out antidoping efforts that aim for abstinence? We provide an outline of an alternative policy, allowing a cautious step-wise change to answer this question and then discuss the ethical aspects of such a policy change. (shrink)

It has often been remarked that the metatheory of strong reduction $\succ$ , the combinatory analogue of βη-reduction ${\twoheadrightarrow_{\beta\eta}}$ in λ-calculus, is rather complicated. In particular, although the confluence of $\succ$ is an easy consequence of ${\twoheadrightarrow_{\beta\eta}}$ being confluent, no direct proof of this fact is known. Curry and Hindley’s problem, dating back to 1958, asks for a self-contained proof of the confluence of $\succ$ , one which makes no detour through λ-calculus. We answer positively to this question, by extending (...) and exploiting the technique of transitivity elimination for ‘analytic’ combinatory proof systems, which has been introduced in previous papers of ours. Indeed, a very short proof of the confluence of $\succ$ immediately follows from the main result of the present paper, namely that a certain analytic proof system G e [ $\mathbb {C}$ ] , which is equivalent to the standard proof system CL ext of Combinatory Logic with extensionality, admits effective transitivity elimination. In turn, the proof of transitivity elimination—which, by the way, we are able to provide not only for G e [ $\mathbb {C}$ ] but also, in full generality, for arbitrary analytic combinatory systems with extensionality—employs purely proof-theoretical techniques, and is entirely contained within the theory of combinators.

Cognitive dissonance has been studied for more than sixty years and many insightful findings have come from this research. However, some important theoretical and methodological issues are yet to be resolved, particularly regarding dissonance reduction. In this paper, we place dissonance theory in the larger framework of appraisal theories of emotion, emotion regulation, and coping. The basic premise of dissonance theory is that people experience negative affect (to varying degrees) following the detection of cognitive conflict. The individual will be motivated (...) to alleviate these emotional reactions and could do so by reducing dissonance in some manner. We argue that detection of dissonance will follow the same principles as when people interpret any other stimuli as emotionally significant. Thus, appraisal theory of emotion, which argues that emotions are generated via the cognitive evaluation of surrounding stimuli, should be applicable to the dissonance-detection process. In short, we argue that dissonance-reduction strategies (attitude change, trivialization, denial of responsibility, etc.) can be understood as emotion-regulation strategies. We further argue that this perspective contributes to reconciling fragmented (and sometimes contrary) viewpoints present in the literature on dissonance reduction. In addition to proposing the general model of dissonance reduction, we illustrate at the hand of empirical data how research on dissonance reduction can be performed without relying on experimental paradigms that focus on a specific reduction strategy.

It is frequently said that biology is emerging from a long phase of reductionism. It would be certainly more correct to say that biologists are abandoning a certain form of reductionism. We describe this past form, and the experiments which challenged the previous vision. To face the difficulties which were met, biologists use a series of concepts and metaphors - pleiotropy, tinkering, epigenetics - the ambiguity of which masks the difficulties, instead of solving them. In a similar way, the word (...) “post-genomics” has different meanings, depending upon who uses it. Which of these meanings will become dominant in the future is an open question. (shrink)

This book collects twelve original articles, arranged in three sections, plus an introduction.

Arguments, claims, and discussions about the “level of description” of a theory are ubiquitous in cognitive science. Such talk is typically expressed more precisely in terms of the granularity of the theory, or in terms of Marr’s three levels. I argue that these ways of understanding levels of description are insufficient to capture the range of different types of theoretical commitments that one can have in cognitive science. When we understand these commitments as points in a multi-dimensional space, we find (...) that we must also reconsider our understanding of intertheoretic relations. In particular, we should understand cognitive theories as constraining one another, rather than reducing to one another. (shrink)

The debate between emergentists and reductionists rests on the observation that in many situations, in which it seems desirable to work with a coherent and unified discourse, key predicates fall into different groups, such that pairs of members one taken from each group, cannot be co-predicated of some common subject. Must we settle for ‘island’ discourses in science and human affairs or is some route to a unified discourse still open? To make progress towards resolving the issue the conditions under (...) which such segregations of predicates seem inexorable must be brought out. The distinction between determinable and determinate properties throws light on some aspects of this problem. Bohr’s concept of complementarity, when combined with Gibson’s idea of an affordances as a special class of dispositional properties is helpful. Several seeming problems melt away, for example, how it is possible for a group of notes to become hearable as a melody. The mind-body problem and the viability of the project of reducing biology to chemistry and physics are two issues that are more difficult to deal with. Are mental phenomena, such as feelings and memories emergent from material systems or are they actually material properties themselves? Are the attributes of living beings emergent from certain accidental but long running collocations of chemical reactions, or are they nothing but chemical phenomena? If emergent, in what way are they distinctive from that from which they emerge? (shrink)

Non-naturalists claim that the nature of normativity precludes the possibility of normative naturalism. In particular, they think that normative reduction amounts to normative elimination. This is because it always leaves out the normative. In this paper, I examine the force that the normativity objection has against Humean reductionism. I argue that the normativity objection has no argumentative force against reductionism. When it is presented as a bare intuition, it begs the question against reduction. A more interesting reading of the argument (...) claims that the normative cannot be explained in terms of the natural because the natural is arbitrary. Yet, this version of the argument fails as well because the natural is not arbitrary in the relevant sense. The natural is contingent, so what has value is contingent. That is not an elimination of the normative though, because contingent reasons are still reasons. (shrink)

So far, the value dimension underlying affectivity disorders has remained out of focus in phenomenological psychopathology. As early as at the beginning of the 20th century, however, German phenomenologist Max Scheler examined in depth the relationship between affectivity and value dimension through the concept of valueception (Wertnehmung). In this sense, a recent noteworthy contribution has been provided by John Cutting, who has drawn attention to the importance of Scheler’s analyses for psychiatry. In this work I take into consideration only two (...) aspects of Cutting’s proposal: 1) the relationship between the impairments of valueception and the perception of certain value classes; and 2) the interpretation of Scheler’s phenomenological reduction and its juxtaposition with the modus vivendi of schizophrenia. According to Cutting, in the modus vivendi of schizophrenia the valueception impairment entails putting vital values in brackets and focusing on personal values, with a process that recalls Scheler’s phenomenological reduction. Regarding the first aspect, I share Cutting’s starting point, but then shift the focus on how important the valueception is for the intersubjective dimension. In particular, I maintain that rather than compromising the perception of vital values, valueception impairments in the modus vivendi of schizophrenia interfere with the intersubjective dimension and are interwoven with a process of disembodiment. My thesis is that the modus vivendi of schizophrenia involves a disturbance of the intersubjective dimension that arises from the level of valueception and that determines the person’s self-referential closure. With regard to the second point, by analyzing Scheler’s phenomenological reduction, I sustain that its main objective is to increase both the interaction with otherness and the openness to the world (Weltoffenheit). As a consequence, the modus vivendi of schizophrenia, in my opinion, is not comparable, as Cutting claims, with Scheler’s phenomenological reduction, but goes in a different direction. (shrink)

We are unlikely to stop seeking pleasure, as this would prejudice our health and well-being. Yet many psychoactive substances providing pleasure are outlawed as illicit recreational drugs, despite the fact that only some of them are addictive to some people. Efforts to redress their prohibition, or to reform legislation so that penalties are proportionate to harm have largely failed. Yet, if choices over seeking pleasure are ethical insofar as they avoid harm to oneself or others, public health strategies should foster (...) ethical choice by moving beyond current risk management practices embodied in the harm reduction movement. The neuroscience of pleasure has much to offer neuroethics and public health strategies. Distinguishing between ‘wanting’ and ‘liking’ fosters new understandings of addiction. These hold promise for directing the search for pharmacotherapies which prevent addiction and relapse or disrupt associated neuromechanisms. They could inform new research into creating lawful psychoactive substances which give us pleasure without provoking addiction. As the health and well being of human and other animals rests upon the experience of pleasure, this would be an ethical objective within public health strategy. Were ethical and neurobiological obstacles to ending addiction to be overcome, problems associated with excessive consumption, the lure of unlawful psychoactive substances and the paucity of lawful means to achieve pleasurable altered states would remain. Non-addictive designer drugs, which reliably provided lawful access to pleasures and altered states, would ameliorate these public health concerns insofar as they fostered citizens’ informed, ethical choices according to a neurobiological taxonomy of pleasures.
