Our aim in this paper is to defend the reductionist (or deflationist) view on group testimony from the attacks of divergence arguments. We will begin by presenting how divergence arguments can challenge the reductionist view. However, we will argue that these arguments are not decisive to rule out the reductionist view; for, these arguments have false premises, assuming dubious epistemic principles that testimony cannot generate knowledge and understanding. The final part of this paper will (...) be devoted to presenting the advantages of the reductionist approach to explaining the phenomenon of group testimony. (shrink)

In Reasons and Persons, Derek Parfit argues for a Reductionist View of personal identity. According to a Reductionist, persons are nothing over and above the existence of certain mental and/or physical states and their various relations. Given this, Parfit believes that facts about personal identity just consist in more particular facts concerning psychological continuity and/or connectedness, and thus that personal identity can be reduced to this continuity and/or connectedness. Parfit is aware that his view of personal (...) identity is contrary to what many people ordinarily think about persons, and thus if his view is correct, many of us have false beliefs about personal identity. Further, since many of our views about morality are based upon our views about personal identity, it follows that we may also have to change our beliefs about morality as well. Parfit, however, thinks that in many cases such changes represent an improvement over our former beliefs and better fit with our considered moral judgments. But instead, I argue that Parfit’s account poses a serious threat to considered moral judgments, and, in particular, that it seriously undermines any substantial notion of moral commitment. As such, even if Parfit is metaphysically correct, I suggest we may have practical reasons, based on our moral concerns, for holding to a more weighty view of the nature of persons. (shrink)

This paper presents an ontological perspective that enables evaluating the effectiveness of business models from an integrative worldview. Different groups’ fragmented and reductionist views on this topic create a dichotomy that makes it difficult to compare and analyze them in practice. Such groups use different values for some components, which may result in neglecting others and their interrelationship. This study discusses a functional characteristic of business models that academia still needs to address. It explores new frontiers in the field, (...) such as business models for networks, sustainability, and their practical evaluation. To achieve an integrative ontology and avoid focusing on specific constructs or systems at the expense of others, we draw upon the theory of worldviews from Wilhelm Dilthey, reformational philosophy, and Herman Dooyeweerd’s theory of modal aspects. Society should move beyond dualistic thinking and embrace practical and applicable solutions. To help companies develop effective models, we introduce a new business model framework based on an integrative worldview that enables comparisons and evaluations of companies in practice. Creating competitive advantages and value appropriations synergizes with essential aspects of reformational philosophy. Analyzing and interrelating such elements are fundamental to understanding the real applied value of business models. (shrink)

The timeliness of the problem of reduction is due above all to the successes of application of the techniques of the exact sciences in biology. To the extent that molecular biology "gets down to" the initial, fundamental mechanisms of the processes of life, it is impossible for it to remain purely in the realm of statement of facts; it cannot but affect methodological principles of the study of life. "The history of biology clearly demonstrates the striking regularity with which the (...) problem of reductionism arises each time biological knowledge advances to a new level." The counterposing of mechanism and vitalism, elementarism and organicism, etc., was replaced by new forms of methodological discussion born of the achievements of experimental knowledge of life and the demands that this be formulated into theory. To separate the principle of reduction, productive in current biological research, from biological reductionism based on the elevation of this principle to an absolute is the meaning of the current struggle against mechanistic trends in biology. The mechanicism of the present day rests primarily on the productiveness of the methods of physical chemistry in adding to knowledge of life; and therefore when people speak of the problem of reductionism, discussion of the potentials of the investigation of life by molecular biology and the limits of those potentials takes pride of place.

are often used loosely – especially in medical contexts. In an attempt to remedy this, these terms are explored from the standpoints of: philosophy of science, medicine, genetics, history of genetics and clinical genetics. A sense for ‘reductionism’ is developed in part by focusing on the related histories of classical genetics and clinical genetics. This done, the dichotomy between holism and reductionism, whether in basic genetics or the genetic counseling situation, loses much of its force. CiteULike Connotea Del.icio.us What's this?

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)

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)

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

It is generally believed that moral reductionism is immune from notorious problems in moral metaphysics and epistemology, such as the problem of moral explanation – it is at least on this dimension that moral reductionism scores better than moral anti- reductionism. However, in this article I reject this popular view. First, I argue that moral reductionism fails to help vindicate the explanatory efficacy of moral properties because the reductionist solution is either circular or otiose. Second, I attempt to (...) show that a successful vindication, if any, of moral explanation requires moral-descriptive irreducibility. My discussion thus raises an explanatory challenge to moral reductionism. (shrink)

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

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.

P. Kitcher's unification theory of explanation appears to endorse a reductionistic view of scientific explanation that is inconsistant with scientific practice. In this paper, I argue that this appearance is illusory. The existence of multiply realizable generalizations enable the unification theory to also count many high-level accounts as explanatory.

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 REASONS AND PERSONS, Derek Parfit defends a conception of the self or person which he labels "Reductionist." It is a conception which owes much to Hume's view of the self as a bundle of causally connected perceptions. Indeed, Parfit's account might be thought of as capturing the best insights of the bundle theory, while avoiding many of the objections to which cruder versions of that theory appear to be liable. Parfit's preliminary characterization of Reductionism is in connection (...) with the notion of personal identity. A Reductionist view of personal identity holds that: the fact of a person's identity over time just consists in the holding of certain more particular facts, and these facts can be described without either presupposing the identity of this person, or explicitly claiming that this person exists. These facts can be described in an impersonal way. (shrink)

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

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)

Several authors have commented on my reductionist account of spirituality in nursing, describing it variously as naïve, disrespectful, demeaning, paternalistic, arrogant, reifying, indicative of a closed mind, akin to positivism, a procrustean bed, a perpetuation of fraud, a matter of faith, an attempt to secure ideological power, and a perspective that puritanically forbids interesting philosophical topics. In responding to this list of felonies and misdemeanours, I try to justify my excesses by arguing that the critics have not really understood (...) what reductionism involves; that rejecting reductionism is not the same as providing arguments against it; that the ethical dilemmas allegedly associated with reductionist views are endemic to health care; that 'reifying' is what believers in the spiritual realm do; and that the closed minds belong to those who dismiss reductionist science without having studied its achievements.

While committed to the view that Buddhist Reductionism offers the best account of the Abhidharma distinction of the two truths, Siderits (2009) argues that Buddhist Reductionism has the surprising consequence of making itself inexpressible. This inexpressibility follows from the semantic insulation between conventional and ultimate discourses that Siderits argues is required in order to preserve classical logic for both types of discourse, avoiding contradiction and bivalence failure. I argue that inexpressibility is a problematic consequence that threatens to constitute a (...) reductio of Buddhist Reductionism. (shrink)

While Derek Parfit is aware that his reductionism about persons is anticipated in early Buddhism and Abhidharma, he has not explored that tradition for any clues it might yield concerning the consequences of adopting the position.

While these turn out to be significant, it is argued here that this (...) is a price a reductionist should be prepared to pay. (shrink)

Biosmiotics is trying to extend semiotic concepts to biological phenomena and demarcate the biological sphere from the non-biological sphere using the applicability or inapplicability of semiotics as the demarcation criterion. We could call it antireductionsit in the first part of its enterprise as the world of life is interpreted in quasi-human terms; and we coulld call it reductionist in the second part of its enterprise as, for example, causality is excluded from the semiotic sphere. This article promotes a (...) class='Hi'>view according to which applicability of semiotic concepts cannot serve as a demarcation criterion to partition reality plainly because the extensions of the concepts of semiosis, cogntion, subjectivity, and -- surprisingly -- causality, coincide.

A survey of arguments for and against the view that colors are physical properties.

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.

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.

In this paper, I explore the possibilities for arriving at a useful conception of methodological reductionism. Some participants in the debate talk about methodological reductionism as a research program. I argue that the concept of a research program, at least in Lakatos’ sense, cannot account for the diverse nature of methodological reductionism. I then present my own concept of a research directive as a useful alternative and elaborate on this by drawing on Hasok Chang’s theory of ontological principles and epistemic (...) activities. According to my view, the reductionist research directive can be characterized as consisting of the principles fundamental ontological homogeneity, part-whole asymmetry, and orderliness, together with the corresponding activities construction of identities, decomposition, and unification. I suggest that looking at reductionism in this way enables us to understand it as a gradual concept and thus go beyond the simplistic yes-or-no-questions that dominate many current debates on this topic.

We have lived under the hegemony of the reductionistic scientific worldview since Galileo, Newton, and Laplace. In this view, the universe is meaningless, as Stephen Weinberg famously said, and organisms and a court of law are "nothing but" particles in morion. This scientific view is inadequate. Physicists are beginning to abandon reductionism in favor of emergence. Emergence, both epistemological and ontological, embraces the emergence of life and of agency. With agency comes meaning, value, and doing, beyond mere happenings. (...) More organisms are conscious. None of this violates any laws of physics, but it cannot be reduced to physics. Emergence is real, and the tiger chasing the gazelle are real parts of the real universe. We live, therefore, in an emergent universe. This emergence often is entirely unpredictable beforehand, from the evolution of novel functionalities in organisms to the evolution of the economy and human history. We are surrounded on all sides by a creativity that cannot even be prestated. Thus we have the first glimmerings of a new scientific worldview, beyond reductionism. In our universe emergence is real, and there is ceaseless, stunning creativity that has given rise to our biosphere, our humanity, and our history. We are partial co-creators of this emergent creativity. It is our choice whether we use the God word. I believe it is wise to do so. God can be our shared name for the true creativity in the natural universe. Such a view invites a new sense of the sacred, as those aspects of the creativity in the universe that we deem worthy of holding sacred. We are not logically forced to this view. Yet a global civilization, hopefully persistently diverse and creative, is emerging. I believe we need a shared view of God, a fully natural God, to orient our lives. We need a shared view of the sacred that is open to slow evolution, because rigidity in our view of the sacred violates how our most precious values evolve and invites ethical hegemony. We need a shared global ethic beyond our materialism. I believe a sense of God as the natural, awesome creativity in the universe can help us construct the sacred and a global ethic to help shape the global civilization toward what we choose with the best of our limited wisdom.

I offer support for the view that physicalist theories of cognition don't reduce to neurophysiological theories. On my view, the mind-brain relationship is to be explained in terms of evolutionary forces, some of which tug in the direction of a reductionistic mind-brain relationship, and some of which which tug in the opposite direction. This theory of forces makes possible an anti-reductionist account of the cognitive mind-brain relationship which avoids psychophysical anomalism. This theory thus also responds to the (...) complaint which arguably lies behind the Churchlands' strongest criticisms of anti-reductionism — namely the complaint that anti-reductionists fail to supply principled explanations for the character of the mind-brain relationship. While lending support to anti-reductionism, the view defended here also insures a permanent place for mind-brain reduction as an explanatory ideal analogous to Newtonian inertial motion or Aristotelian natural motion.

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

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

Abstract The goal of this chapter is to provide an opinionated overview of the psychologically based account of personal identity and the role of agency within such an account. I describe the essential points of the psychological criterion of personal identity. Then, I discuss how the psychological criterion is related to the Reductionist View of personal identity and whether it is committed to what Derek Parfit names the Extreme Claim. I further discuss how the agency-based views of personal (...) identity can be accommodated within Derek Parfit’s psychologically based view of personal identity. I end the chapter by discussing how an agency-based view, as most notably developed by Christine Korsgaard, could be used to vindicate practical concerns that are traditionally related to personal identity.

Attempts to explain Peirce’s various classifications of signs have been a preoccupation of many Peirce scholars. Opinions are mixed about the sense, coherence, and fruitfulness of Peirce’s various versions, particularly the latter ones. I argue here that it is not a fruitful enterprise, even if sense could be made of them. Although Peirce makes his motivations for the classification of the sciences fairly explicit, it’s hard to find Peirce’s reasons for sign classification. More importantly, I try to make the case (...) that such classifications are premised on a reductionist framework of semiosis that is contrary to the irreducible triadic character of signs that Peirce otherwise espouses. The reductionism is the result of Peirce’s use of certain models for his sign classifications, in particular, Mendeleev’s periodic table. I suggest that the remedy for the reductionism is to re-emphasize the processual and functional view of semiosis, rather than to focus on particular classes of signs. Corresponding to the three triadic conditions of semiosis, I argue that signs function to inform, represent or refer, and interpret, and that understanding these three function and how they interrelate may prove to be a more fruitful approach to sign analysis than sign classification.

As a critic, I am in the unenviable position of agreeing with nearly all of what Mark does in this lucid, erudite and creative book. My comments will hence not be aimed at showing what he got wrong, as much as an attempt from a Madhyamaka point of view to suggest another way of seeing things, in particular another way of seeing how one might think of how Madhyamaka philosophers, such as Någårjuna and Candrak¥rti, see conventional truth, our engagement (...) with conventional truth, and the status of persons. I suspect that this alternative is also in the minds of earlier Buddhist philosophers, and that Madhyamaka may be more an explicit working out of ideas implicit in the tradition than a radical break. If this suspicion—for which I will not argue here—is correct, this alternative is also available to those to whom Mark refers as “reductionists.” I think that this way of seeing things may put certain ideas in Buddhist philosophy into better focus, and may indeed make them more attractive as well.

Paleo-compatibilism is the view that the freedom required for moral responsibility is not incompatible with determinism about the factors relevant to moral assessment, since the claim that we are free and the claim that the psychophysical elements are causally determined are true in distinct and incommensurable ways. This is to be accounted for by appealing to the distinction between conventional truth and ultimate truth developed by Buddhist Reductionists. Paleo-compatibilists hold that the illusion of incompatibilism only arises when we illegitimately (...) mix two distinct vocabularies, one concerned with persons, the other concerned with the parts to which persons are reducible. I explore the view, its roots in Buddhist Reductionism, and its prospects. (shrink)

Almost everyone agrees that many testimonial beliefs constitute knowledge. According to non-reductionists, some testimonial beliefs possess positive epistemic status independent of that conferred by perception, memory, and induction. Recently, Jennifer Lackey has provided a counterexample to a popular version of this view. Here I argue that her counterexample fails.

A common reductionist assumption is that macro-scale behaviors can be described "bottom-up" if only sufficient details about lower-scale processes are available. The view that an "ideal" or "fundamental" physics would be sufficient to explain all macro-scale phenomena has been met with criticism from philosophers of biology. Specifically, scholars have pointed to the impossibility of deducing biological explanations from physical ones, and to the irreducible nature of distinctively biological processes such as gene regulation and evolution. This paper takes a (...) step back in asking whether bottom-up modeling is feasible even when modeling simple physical systems across scales. By comparing examples of multi-scale modeling in physics and biology, we argue that the “tyranny of scales” problem presents a challenge to reductive explanations in both physics and biology. The problem refers to the scale-dependency of physical and biological behaviors that forces researchers to combine different models relying on different scale-specific mathematical strategies and boundary conditions. Analyzing the ways in which different models are combined in multi-scale modeling also has implications for the relation between physics and biology. Contrary to the assumption that physical science approaches provide reductive explanations in biology, we exemplify how inputs from physics often reveal the importance of macro-scale models and explanations. We illustrate this through an examination of the role of biomechanics modeling in developmental biology. In such contexts, the relation between models at different scales and from different disciplines is neither reductive nor completely autonomous, but interdependent. (shrink)

It has been suggested that Marr took the three levels he famously identifies to be independent. In this paper, we argue that Marr's view is more nuanced. Specifically, we show that the view explicitly articulated in his work attempts to integrate the levels, and in doing so results in Marr attacking both reductionism and vagueness. The result is a perspective in which both high-level information-processing constraints and low-level implementational constraints play mutually reinforcing and constraining roles. We discuss our (...) recent work on Spaun—currently the world's largest functional brain model—that demonstrates the positive impact of this kind of unifying integration of Marr's levels. We argue that this kind of integration avoids his concerns with both reductionism and vagueness. In short, we suggest that the methods behind Spaun can be used to satisfy Marr's explicit interest in combining high-level functional and detailed mechanistic explanations. (shrink)

I argue that a certain version of physicalism, which is viewed by both its admirers and its detractors as non-reductionist, in fact entails two claims which, though not reductionist in the currently most popular sense of 'reductionist', conform to the spirit of reductionism sufficiently closely to compromise its claim to be a comprehensively non-reductionist version of physicalism. Putatively non-reductionist versions of physicalism in general, I suggest, are likely to be non-reductionist only in some senses, (...) but not in others, and hence to disappoint those who wish to be physicalists but still to remain soft and cuddly non-reductionists.

Effective field theories have been a very popular tool in quantum physics for almost two decades. And there are good reasons for this. I will argue that effective field theories share many of the advantages of both fundamental theories and phenomenological models, while avoiding their respective shortcomings. They are, for example, flexible enough to cover a wide range of phenomena, and concrete enough to provide a detailed story of the specific mechanisms at work at a given energy scale. So will (...) all of physics eventually converge on effective field theories? This paper argues that good scientific research can be characterised by a fruitful interaction between fundamental theories, phenomenological models and effective field theories. All of them have their appropriate functions in the research process, and all of them are indispensable. They complement each other and hang together in a coherent way which I shall characterise in some detail. To illustrate all this I will present a case study from nuclear and particle physics. The resulting view about scientific theorising is inherently pluralistic, and has implications for the debates about reductionism and scientific explanation. (shrink)

This paper inquires into the nature of intertheoretic relations between psychology and neuroscience. This relationship has been characterized by some as one in which psychological explanations eventually will fall away as otiose, overthrown completely by neurobiological ones. Against this view it will be argued that it squares poorly with scientific practices and empirical developments in the cognitive neurosciences. We analyse a case from research on visual perception, which suggests a much more subtle and complex interplay between psychology and neuroscience (...) than a complete take-over of the former by the latter. In the case of vision, cross-theory influences between psychology and neuroscience go back and forth, resulting in refinement in both disciplines. We interpret this case study as showing that: (1) Mutual co-evolution of psychological and neurobiological theories, exemplifying persisting top-down influences from psychology, is a more empirically adequate way to describe psychoneural theory relations than a view on co-evolution, favoured by reductionists, which regards the cross-theory contributions from psychology as merely heuristically useful with no enduring influence on neurobiological theorizing; (2) In research on vision, discovering (or hypothesizing) the neural basis of functions vindicates psychological approaches, it does not eliminate them; (3) Current work on vision shows that many perceptual phenomena must be understood in terms of dynamical interactions between an observer and his/her environment. Therefore, we argue that internalist characterizations of the visual system must be supplemented with externalist accounts that address these reciprocal observer-environment interactions involved in vision. Such processes seem quite different from (internal) cellular and molecular ones, and as such seem to lie outside the scope of neuroscientific inquiry. We conclude that psychoneural reduction or elimination is implausible as a meta-theoretical prediction of theory choice in empirical work. Instead, this case study of vision shows that both psychology and neuroscience contribute to, and complement one another in the study of visual perception. (shrink)

"Reductionism," in this context, is the view that the right to privacy necessarily depends on and derives from more fundamental rights, primarily liberty and property, and that this reduction has important normative implications for the law. Judges and scholars have articulated versions of reductionism for about a century, and yet, since the time of the seminal Pavesich opinion, none of these views has influenced the law. ;In this thesis, I offer a new version of reductionism. I start by examining (...) the original debate concerning the existence of a right to privacy, triggered by the seminal law review article by Warren and Brandeis. I argue that this debate was not resolved in favor of such a right until Justice Cobb, in Pavesich, offered a justification for it based on fundamental political principles. I next examine the debate between the contemporary reductionists Prosser, Thomson, and Posner, and their critics. I demonstrate that reductionists have not learned the lesson implicit in the original debate: if one hopes to gain influence in the area of privacy law, he must justify his theory on the basis of fundamental political principles. Finally, I offer a more coherent and defensible reductionist view, one based on Ayn Rand's theory of individual rights. I use my reductionist theory to explain why certain undesirable outcomes are inherent in privacy law as it currently exists, recommend a return to a jurisprudence of property and liberty, and indicate a method of implementing this recommendation.

Unlike the overall framework of Ernest Nagel's work on reduction, his theory of intertheoretic connection still has life in it. It handles aptly cases where reduction requires complex representation of a target domain. Abandoning his formulation as too liberal was a mistake. Arguments that it is too liberal at best touch only Nagel's deductivist theory of explanation, not his condition of connectability. Taking this condition seriously gives a powerful view of reduction, but one which requires us to index explanatory (...) power to sciences as they are formulated at particular times. While we may thereby reduce more than philosophers have supposed, we must abandon hope (as Nagel did) of saying anything useful about reductionism. (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)

By now it is cliché to observe that so-called reductionism is not one mammoth doctrine. There are, as it were, many reductionisms. Needless to say, there are at least as many antireductionisms. Despite the fact that neither reductionisms nor their counterparts are single and unified doctrines there do seem to be some family resemblances. One, it seems to me, is that both reductionisms and antireductionisms are acute responses to certain metaphysical worries. Some of these worries are metaphysical in nature, and (...) others are worries about the nature of metaphysics. My contention is that these worries are by and large misguided, and thus that the anxious reactions of both reductionists and antireductionists are unwarranted. For the present purposes I will distinguish between reductionist and antireductionist theses, on the one hand, and reductionist and antireductionist approaches, on the other. This is a perhaps clumsy distinction, and I don’t know that it carves reductionism at its joints. But I think it can be made to do some work. By theses I have in mind particular views about the nature of reduction and reductive relations, which can be worked out in various ways some of which will be discussed below. By approaches I have in mind the motivations and background assumptions that go into formulating or adopting particular theses. Individual reductionists and antireductionists usually hold what we might then call a theory, a combination of an approach and a thesis. A great deal has been written about the merits of or truth of any number of 1 reductionist or antireductionist theses. Presumably there are some assumptions about approaches and motivations lurking in the background. But very little has been said about the merits of the various approaches themselves. Put another way: There is a lively debate over whether particular reductionist theses can solve certain problems or avoid certain objections. But not enough attention has been given to whether these are problems worth solving or objections worth overcoming. (shrink)

The extensive philosophical discussions and analyses in recent decades of function-talk in biology have done much to clarify what biologists mean when they ascribe functions to traits, but the basic metaphysical question—is there genuine teleology and design in the natural world, or only the appearance of this?—has persisted, as recent work both defending, and attacking, teleology from a Darwinian perspective, attest. I argue that in the context of standard contemporary evolutionary theory, this is for the most part a verbal, rather (...) than a substantive dispute: the disputants are talking past one another. To justify this claim I develop a general framework within which reductionist views, such as the standard ‘etiological’ account of biofunctions, occupy an intermediate position between what I call full-blooded realism and full-blooded anti-realism, and suggest that whether such views count as ‘realist’ views has no objective, theory-neutral answer.
