Positing levels of explanation has played an important role in philosophy of science. This facilitated the advocacy of antireductionism of explanations, which, at its most basic, is the idea that scientific explanations citing large (i.e. non-microphysical) entities will persist. The idea that explanations come in levels captures important features of explanatory practices, and it also does well at helping to define different positions one might take regarding explanatory reductionism or antireductionism. Yet the idea that explanations come in levels (...) has also led philosophers astray. This systematically misconstrues the relationship different explanations bear to one another, suggests candidate explanations are less numerous than they in fact are, and occludes recognition of how the selection of explanations can vary across research projects. Antireductionists about explanation should move on from talk of levels. Or so I will argue. (shrink)

In this paper I provide a novel argument against the claim that classical genetics is being reduced to molecular genetics. Specifically, I demonstrate that reductionists must subscribe to the unargued and problematic thesis that molecular genetics is 'independent' of classical genetics. I also argue that several standard antireductionist positions can be faulted for unnecessarily conceding the Independence Thesis to the reductionists. In place of a 'tale of two sciences', I offer a 'heroic' stance that denies classical genetics is being reduced, (...) yet sees classical and molecular genetics as fundamentally unified. (shrink)

I develop a novel argument against the claim that ordinals are sets. In contrast to Benacerraf’s antireductionist argument, I make no use of covert epistemic assumptions. Instead, my argument uses considerations of ontological dependence. I draw on the datum that sets depend immediately and asymmetrically on their elements and argue that this datum is incompatible with reductionism, given plausible assumptions about the dependence profile of ordinals. In addition, I show that a structurally similar argument can be made against the claim (...) that cardinals are sets. (shrink)

Beginning in the 1970s and culminating in the first two decades of the 21st century, there has been a marked shift in the sciences from a predominantly reductionist and mechanistic approach to a broader and more holistic viewpoint. It goes without saying that such a shift in point of view will have significant implications, not only for the sciences but for our concepts of nature and of human beings. The present essay is an attempt to assess the significance of this (...) change in the focus of the sciences and to describe the nature of its components. Originally, it had a far more limited scope, that of comparing two of the parts of the new nonreductionist stance: brain plasticity and biological systems theory. Unfortunately, my understanding of one of these factors (systems theory) turned out to be incorrect, while the section on brain plasticity was incomplete. The result of this dual realization is an essay of far greater scope, taking in both new developments in the sciences far beyond that of plasticity, and reassessing the content and impact of systems theory, which is greater than I had thought. I will begin with a study of systems theory, dealing first with the unexpected mathematics which made its present status possible. Then I will deal with its history, which reaches back over a century. One of the confusions into which we are liable to fall is to fail to distinguish the old systems theory from the new. This is even more likely because the two versions of the theory have many features in common. (shrink)

Emergent antireductionism in biological sciences states that even though all living cells and organisms are composed of molecules, molecular wholes are characterized by emergent properties that can only be understood from the perspective of cellular and organismal levels of composition. Thus, an emergence claim (molecular wholes are characterized by emergent properties) is thought to support a form of antireductionism (properties of higher-level molecular wholes can only be understood by taking into account concepts, theories and explanations dealing with higher-level (...) entities). I argue that this argument is flawed: even if molecular wholes are characterized by emergent properties and even if many successful explanations in biology are not molecular, there is no entailment between the two claims.

Reductionism and antireductionism are among the most largely and hotly debated topics in philosophy of biology today. In this section of the volume, aiming to convey the current situation in the philosophy of the natural and life sciences, these topics are specifically addressed in Mehmet Elgin’s paper, focusing on biochemistry. Elgin strongly supports reductionism, first by claiming that the now classical argument based on multiple realizability does not entail anti-reductionism and secondly highlighting how the version of methodological reductionism that (...) biochemistry has been adopting – centered on “the principle that biological functions of biomolecules in living cells can be understood in terms of chemical and physical properties of those molecules”1 – has proved largely successful, teaching “us new knowledge about the biological systems”. Taken together, these two arguments are deemed to provide good grounds for a thorough defence of reductionism. While Elgin chooses biochemistry as his privileged standpoint on the issue, I shall dwell on the stances emerging in the health sciences. Although the health sciences are closely intertwined with – amongst others – biology and biochemistry, they also have their own peculiar features. Referring to some examples taken from different medical disciplines, I will question whether reductionism can be regarded as not only a viable, option, but as the best solution to gain new knowledge about biomedical systems. I shall suggest that considerations arising from current medical research and practice support a pluralistic approach to the topic, in which both reductionist and antireductionist stances can be accommodated in different ways.

Philosophers now treat the relationship between classical genetics and molecular biology as a paradigm of nonreduction and this example is playing an increasingly prominent role in debates about the reducibility of theories in other sciences. This paper shows that the anti-reductionist consensus about genetics will not withstand serious scrutiny. In addition to defusing the main anti-reductionist objections, this critical analysis uncovers tell-tale signs of a significant reduction in progress. It also identifies philosophical issues relevant to gaining a better understanding of (...) what is now happening in genetics and of what we might expect to happen in other sciences. (shrink)

Physicalism and antireductionism are the ruling orthodoxy in the philosophy of biology. But these two theses are difficult to reconcile. Merely embracing an epistemic antireductionism will not suffice, as both reductionists and antireductionists accept that given our cognitive interests and limitations, non-molecular explanations may not be improved, corrected or grounded in molecular ones. Moreover, antireductionists themselves view their claim as a metaphysical or ontological one about the existence of facts molecular biology cannot identify, express, or explain. However, this (...) is tantamount to a rejection of physicalism and so causes the antireductionist discomfort. In this paper we argue that vindicating physicalism requires a physicalistic account of the principle of natural selection, and we provide such an account. The most important pay-off to the account is that it provides for the very sort of autonomy from the physical that antireductionists need without threatening their commitment to physicalism.

Scholars are divided as to whether reduction should be a central strategy for understanding the world. While reductive analysis is the standard mode of explanation in many areas of science and everyday life, many scholars consider reductionism a sign of “intellectual naïveté and backwardness.” This article makes three points about the proper status of antireductionism: First, reduction is, in fact, a centrally important epistemic strategy. Second, reduction to physics is always possible for all causal properties. Third, there are, nevertheless, (...) reasons why we want science to discover properties and explanations other than reductive physical ones. (shrink)

It has been debated what implications multiple realizability has for reductionism. I claim that more explicit attention needs to be paid to the distinction between multiple realizations of kinds and diverse implementations of laws. In this paper, I distinguish two different theses on the relations between multiple realization and diverse implementation: one thesis states that multiple realizations imply diverse implementations and the other states the converse. I claim that although antireductionism might turn out to be false if the first (...) thesis is accepted, this “realization‐based” antireductionism is not the only option for antireductionism. For the antireductionists who accept the second thesis, multiple realizations only provide evidence for diverse implementations. I defend this “implementation‐based” antireductionism again Shapiro's dilemma. I argue that one horn of the dilemma does not pose any problem and that the other horn simply begs the question.

Building on previous work, I continue the arguments for scientific realism in the presence of a natural level structure of science. That structure results from a cognitive antireductionism that calls for the retention of mature theories even though they have been "superseded". The level structure is based on "scientific truth" characterized by a theory's validity domain and the confirming empirical data. Reductionism (including fundamentalism) fails cognitively because of qualitative differences in the ontology and semantics of successive theories. This cognitive (...) failure exists in spite of the mathematical success of theory reduction. The claim for scientific realism is strongly based on theory coherence between theories on adjacent levels. Level coherence consists of mathematical relations between levels, as well as of reductive explanations. The latter refers to questions that can be posed (but not answered) on a superseded level, but which can be answered (explained) on the superseding level. In view of the pluralism generated by cognitive antireductionism, theory coherence is claimed to be so compelling that it provides strong epistemic justification for a pluralistic scientific realism.

It is widely held that (1) there are autonomous levels of organization above that of the macromolecule and that (2) at least sometimes macromolecular processes are best explained in terms of such autonomous kinds. I argue that molecular developmental biology honors neither of these claims, and I show that the only way they can be rendered consistent with a minimal physicalism is through the adoption of controversial claims about causation and explanation which undercut the force of these two antireductionism (...) claims.

In this paper, I argue that Husserl offers an important, although almost completely neglected so far, contribution to the reductionist/antireductionist debate about testimony. Through a phenomenological analysis, Husserl shows that testimony works through the constitution of an intentional intersubjective bond between the speaker and the hearer. In this paper I focus on the Logical Investigations, a 1914 manuscript now published as text 2 in Husserliana 20.2, and a 1931 manuscript now published as Appendix 12 in Husserliana 15. I argue that, (...) in those texts, Husserl highlights three essential phenomenological features of testimony: a) testimony is personal, meaning that it only takes place among persons, b) testimony is social, meaning that it requires the joint effort of multiple cognitive agents, c) testimony is community-building, meaning that it generates a long-lasting social bond among the parts involved.

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 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. Both positive and negative lessons will be taken from Jakob von Uexküll's ideas by both developing and criticizing them. (shrink)

Jaegwon Kim attempts to pose a dilemma for anyone who would deny mind/body reductionism, namely that one must either advocate the wholesale reduction of psychology to physical science or the sundering of psychology into distinct fields each one of which is reducible to physical science. Supposedly, the denial of mind/body reduction is not an option. My aim is to show that this is not a genuine dilemma, and that antireductionism is an option, if one recognizes that natural-kind individuation is (...) not wholly a matter of metaphysics but is, at least to some degree, a matter of convention as well. The central point is that physical sciences and mental sciences have somewhat different criteria for individuating kinds. (shrink)

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

: Michael Gazzaniga, a prominent cognitive neuroscientist, has argued against reductionist accounts of cognition. Instead, Gazzaniga defends a form of non-reductive physicalism: epistemological neuro-cognitive non-reductionism and ontological monist physicalism. His position is motivated by the theses that: cognitive phenomena can be realized by multiple neural systems; many outcomes of these systems are unpredictable; and multi-level explanations are required. Epistemological neuro-cognitive non-reductionism is presented as the most appropriate stance to account for the way in which phenomena should be explained in cognitive (...) neuroscience. In this paper, I argue, however, that a recent form of neuro-cognitive reductionism, namely neo-mechanistic reductionism accounts for the arguments presented by Gazzaniga. Thus, the theory offers a more consistent and well-articulated view of the relationship between cognitive and neural phenomena that is specifically compatible with the explanatory strategies and aims of contemporary cognitive neuroscience. Keywords: Neo-mechanistic Philosophy; Michael Gazzaniga; Non-reductionism; Reductionism; Philosophy of Cognitive Neuroscience L’antiriduzionismo neurocognitivo di Michael Gazzaniga e la sfida della riduzione neomeccanicista Riassunto: Uno dei più importanti neuroscienziati dei nostri tempi, Michael Gazzaniga, si è schierato contro una concezione riduzionista della cognizione. Al contrario Gazzaniga difende una forma di fisicalismo non-riduzionistico che risulta dalla combinazione, sul piano epistemologico, di un anti-riduzionismo cognitivo e, sul piano ontologico, di un monismo fisicalista. La sua posizione è motivata dalla tesi per cui i fenomeni cognitivi possono essere realizzati da molteplici sistemi neurali; molti esiti di tali sistemi non si possono prevedere; e sono pertanto necessarie spiegazioni a livelli plurimi. La concezione presentata come più adeguata per dare conto sul piano epistemologico di come i fenomeni dovrebbero essere spiegati all’interno delle neuroscienze cognitive è una forma di anti-riduzionismo neuro-cognitivo. In questo articolo si sostiene tuttavia che una recente forma di riduzionismo neuro-cognitivo può dare conto degli argomenti presentati da Gazzaniga. Si tratta di una teoria che offre una interpretazione maggiormente coerente ed articolata della relazione fra fenomeni cognitivi e neurali e che offre un modello di spiegazione compatibile con gli scopi esplicativi delle neuroscienze cognitive contemporanee.

Reductionism and holism, that is, antireductionism, are two of the prevailing paradigms within the philosophy of biology. Reductionists strive to understand biological phenomena by reducing them to a series of levels of complexity with each lower level forming the foundation for the subsequent level, by mapping such biological phenomena inasmuch as possible to the principal phenomena within the fundamental sciences of chemistry and physics. In this way, complex phenomena can be reduced to assemblages of more elementary explananda. Holism, in (...) counterpart, claims that there independently exist phenomena arising from ordered levels of complexity that have intrinsic causal power and cannot be reduced in this way. When dealing with the nature of biology and its unique foundations of essentialism, determinism and ethics, the pedagogical lens through which these foundations are conveyed to learners could provide a limited perspective if only the reductive approach is followed as it would not sensitise learners to the true complexity of the phenomenon of life and the study thereof, and it is the purpose of this article to frame the reductionist–antireductionist debate in order to illustrate this.Contribution: This article contributes new knowledge to the field of the philosophy of science; more specifically, the philosophy of biology by critically evaluating the pervasive dialectic between the theoretical frameworks of reductionism and antireductionism and alluding to the pedagogical consequences thereof.

To understand how Richard Rorty's “redescription” of transcendental arguments works against the realist interpretation – and in particular against the notion that philosophy can provide an answer to the quaestio juris – it is helpful to turn to a little history. In Anglophone philosophy, the development of the anti‐skeptical and antireductionist potential of transcendental arguments is usually ascribed to the work of P. F. Strawson and other philosophers influenced by the later L. Wittgenstein. According to Rorty, the following condition is (...) sufficient for designating an argument “realist”: a distinction is made between scheme and content. A transcendental argument against realism is an argument to the effect that attempts to make sense of a notion of justification that would do the work of legitimation required is parasitic on what can be gleaned from the methods of confirmation/inferential relations that we use in practice.

This paper argues that the consensus physicalist antireductionism in the philosophy of biology cannot accommodate the research strategy or indeed the recent findings of molecular developmental biology. After describing Wolperts programmatic claims on its behalf, and recent work by Gehring and others to identify the molecular determinants of development, the paper attempts to identify the relationship between evolutionary and developmental biology by reconciling two apparently conflicting accounts of bio-function – Wrights and Nagels (as elaborated by Cummins). Finally, the paper (...) seeks a way of defending the two central theses of physicalist antireductionism in the light of the research program of molecular developmental biology, by sharply reducing their metaphysical force.

Antireductionist philosophers have argued for higher-order classifications of qualia that locate consciousness outside the scope of conventional scientific explanations, viz., by classifying qualia as intrinsic, basic, or subjective properties, antireductionists distinguish qualia from extrinsic, complex, and objective properties, and thereby distinguish conscious mental states from the possible explananda of functionalist or physicalist explanations. I argue that, in important respects, qualia are intrinsic, basic, and subjective properties of conscious mental states, and that, contrary to antireductionists' suggestions, these higher-order classifications are compatible (...) with qualia reduction. I demonstrate this compatibility by examining the putative higher-order properties of qualia and comparing them to the higher-order properties characteristic of connectionist models of cognitive processes. I contend that the higher-order properties characteristic of connectionist networks approximate the putative higher-order properties of qualia sufficiently well to conclude that qualia reductionism can accommodate claims that qualia are intrinsic, basic, and subjective properties, and explain the motivating intuitions for those claims generated by inverted, absent, and alien qualia thought experiments. In this way I argue that the putative higher-order classifications of qualia not only fail to defeat qualia reduction but, ironically, turn out to support it. (shrink)

The antireductionist arguments of many philosophers (e.g., Baker, Fodor and Davidson) are motivated by a worry that successful reduction would eliminate rather than conserve the mental. This worry derives from a misunderstanding of the empiricist account of reduction, which, although it does not underwrite "cognitive suicide", should be rejected for its positivist baggage. Philosophy of psychology needs more detailed attention to issues in natural science which serve as analogies for reduction of the mental. I consider a range of central cases, (...) including water and H 2 O, genes and DNA, and common sense and scientific solidity. The last case is illuminated by Eddington's Two Tables paradox, a resolution which suggests the plasticity of the mental under reduction. If reduction of the mental is like any of these cases, it is neither empiricist nor eliminative. (shrink)

The current antireductionist consensus rests in part on the indefensibility of the deductive-nomological model of explanation, on which classical reductionism depends. I argue that the DN model is inessential to the reductionist program and that mechanism provides a better framework for thinking about reductionism. This runs counter to the contemporary mechanists’ claim that mechanism is an alternative to reductionism. I demonstrate that mechanists are committed to reductionism, as evidenced by the historical roots of the contemporary mechanist program. This view shares (...) certain core commitments with reductionism. It is these shared commitments that constitute the essential elements of the reductionist program. (shrink)

This open access book assesses the prospects of (re)adopting organization as a pivotal concept in biology. It shows how organization can nourish biological thinking and practice, by reconnecting with the idea of biology as the science of organized systems.

It also deals with a variety of themes – including evolution, organogenesis, heredity, cognition and ecology – (...) with respect to which the concept of organization can guide the elaboration of original models and new experimental protocols. It will be of interest to biologists and scholars working in philosophy of science alike. (shrink)

One of the central problems in the philosophy of psychology is an updated version of the old mind-body problem: how levels of theories in the behavioral and brain sciences relate to one another. Many contemporary philosophers of mind believe that cognitive-psychological theories are not reducible to neurological theories. However, this antireductionism has not spawned a revival of dualism. Instead, most nonreductive physicalists prefer the idea of a one-way dependence of the mental on the physical.In Psychoneural Reduction, John Bickle presents (...) a new type of reductionism, one that is stronger than one-way dependency yet sidesteps the arguments that sank classical reductionism. Although he makes some concessions to classical antireductionism, he argues for a relationship between psychology and neurobiology that shares some of the key aims, features, and consequences of classical reductionism. Parts of Bickle's "new wave" reductionism have emerged piecemeal over the past two decades; this is his first comprehensive statement and defense of it to appear. (shrink)

My aim in this paper is to defend a version of the brain process theory, or identity thesis, which differs in one important respect from the theory put forward by J.J.C. Smart. I shall argue that although the sensations which a person experiences are, as a matter of contingent fact, brain processes, nonetheless there are facts about sensations which cannot be described or understood in terms of any physical theory. These 'mental' facts cannot be described by physics for the simple (...) reason that physical descriptions are designed specifically to avoid mentioning such facts. Thus in giving a physical explanation of a sensation we necessarily describe and render intelligible that sensation only as a physical process, and not also as a sensation. If we are to describe and render intelligible a person's sensations, or inner experiences, as sensations, and not as physical processes occurring in that person's brain, then we must employ a kind of description that connot be derived from any set of physical statements.

The Gricean account of language is at the center of much current work in the philosophy of language and the philosophy of mind. Anita Avramides maintains that Grice's paradigm can be used to defend very different conceptions of mind and of meaning. In this clearly argued book she describes Grice's analysis of meaning and proposes two interpretations of it, one reductive and one nonreductive. Much current work in cognitive science assumes that the content of words and thoughts can be explained (...) in naturalistic terms. A leading idea (advanced mainly by Stephen Schiffer and Brian Loar) is that the naturalistic account of content will proceed in two stages: a reduction of the semantic features of word; to the contents of propositional attitudes and then a reduction of the latter to physical or functional notions. The appeal of Grice's work on meaning to this two stage reductionist strategy is that Gricean definitions seem to provide the only way of reducing the semantic to the psychological, a reduction that is required for a naturalistic account of intentionality. While Avramides defends the method of analysis as one suited to the concept of meaning, she rejects a reductive interpretation of the analysis. She argues that any attempt to reduce the semantic to the psychological leads to a mistaken conception of mind. She exposes the assumptions behind the reductive interpretation and offers fresh and original arguments for the antireductionist position. Against the reductive Gricean she defends the idea that there is a deep epistemological symmetry between semantic and propositional attitude notions, a result of which is that semantically characterized linguistic behavior is central to our concept of belief.

The notion of reduction continues to play a key role in philosophy of mind and philosophy of cognitive science. Supporters of reductionism claim that psychological properties or explanations reduce to neural properties or explanations, while antireductionists claim that such reductions are not possible. In this book, I apply recent developments in philosophy of science, particularly the mechanistic explanation paradigm and the interventionist theory of causation, to reassess the traditional approaches to reduction in philosophy of mind. I then elaborate and defend (...) a pluralistic framework for philosophy of mind, and show how reductionist ideas can be incorporated into it. This leads to a novel synthesis of pluralism and reductionism that I call pluralistic physicalism. (shrink)

The question I want to explore is whether experience supports an antireductionist ontology of time, that is, whether we should take it to support an ontology that includes a primitive, monadic property of nowness responsible for the special feel of events in the present, and a relation of passage that events instantiate in virtue of literally passing from the future, to the present, and then into the past.

Research in the psychology of deception detection implies that Fricker, in making her case for reductionism in the epistemology of testimony, overestimates both the epistemic demerits of the antireductionist policy of trusting speakers blindly and the epistemic merits of the reductionist policy of monitoring speakers for trustworthiness: folk psychological prejudices to the contrary notwithstanding, it turns out that monitoring is on a par (in terms both of the reliability of the process and of the sensitivity of the beliefs that it (...) produces) with blind trust. The consequence is that while (a version of) Fricker’s argument for the necessity of a reduction succeeds, her argument for the availability of reductions fails. This does not, however, condemn us to endorse standard pessimistic reductionism, according to which there is no testimonial knowledge, for recent research concerning the methods used by subjects to discover deception in non-laboratory settings suggests that only a more moderate form of pessimism is in order.

The question of the influence of genes on behavior raises difficult philosophical and social issues. In this paper I delineate what I call the Developmentalist Challenge (DC) to assertions of genetic influence on behavior, and then examine the DC through an indepth analysis of the behavioral genetics of the nematode, C. elegans, with some briefer references to work on Drosophila. I argue that eight "rules" relating genes and behavior through environmentally-influenced and tangled neural nets capture the results of developmental and (...) behavioral studies on the nematode. Some elements of the DC are found to be sound and others are criticized. The essay concludes by examining the relations of this study to Kitcher's antireductionist arguments and Bechtel and Richardson's decomposition and localization heuristics. Some implications for human behavioral genetics are also briefly considered. (shrink)

Schaffner’s model of theory reduction has played an important role in philosophy of science and philosophy of biology. Here, the model is found to be problematic because of an internal tension. Indeed, standard antireductionist external criticisms concerning reduction functions and laws in biology do not provide a full picture of the limits of Schaffner’s model. However, despite the internal tension, his model usefully highlights the importance of regulative ideals associated with the search for derivational, and embedding, deductive relations among mathematical (...) structures in theoretical biology. A reconstructed Schaffnerian model could therefore shed light on mathematical theory development in the biological sciences and on the epistemology of mathematical practices more generally. *Received November 2006; revised March 2009. †To contact the author, please write to: Philosophy Department, University of California, Santa Cruz, 1156 High St., Santa Cruz, CA 95064; e‐mail: [email protected].

Watson and Crick’s discovery of the structure of DNA led to developments that transformed many biological sciences. But what were the relevant developments and how did they transform biology? Much of the philosophical discussion concerning this question can be organized around two opposing views: theoretical reductionism and layer-cake antireductionism. Theoretical reductionist and their anti-reductionist foes hold two assumptions in common. First, both hold that biological knowledge is structured like a layer cake, with some biological sciences, such as molecular biology (...) cast at lower levels of organization, and others, such as classical genetics, cast at higher levels. Second, both assume that scientific knowledge is structured by theory and that the productivity of scientific research depends on whether the underlying theory identifies the fundamentals upon which the phenomena to be explained and investigated depend. In the first part of this paper, I challenge these assumptions. In the second part, I show how recasting the basic theory of classical genetics made it possible to retool the methodologies of genetics. It was the investigative power of these retooled methodologies, and not the explanatory power of a gene-based theory, that transformed biology. (shrink)

The argument from multiple realization is currently considered the argument against intertheoretic reduction. Both Little and Kincaid have applied the argument to the individualism-holism debate in support of the antireductionist holist position. The author shows that the tenability of the argument, as applied to the individualism-holism debate, hinges on the descriptive constraints imposed on the individualist position. On a plausible formulation of the individualist position, the argument does not establish that the intertheoretic reduction of social theories is highly unlikely. Nonetheless, (...) the reductive project may run into other potential obstacles. For this reason, it is concluded that the prospect of intertheoretic reduction is uncertain rather than unlikely. Key Words: argument from multiple realization • intertheoretic reduction • reductionism • individualism • holism. (shrink)

Explanatory pluralism holds that the sorts of comprehensive theoretical and ontological economies, which microreductionists and New Wave reductionists envision and which antireductionists fear, offer misleading views of both scientific practice and scientific progress. Both advocates and foes of employing reductionist strategies at the interface of psychology and neuroscience have overplayed the alleged economies that interlevel connections (including identities) justify while overlooking their fundamental role in promoting scientific research. A brief review of research on visual processing provides support for the explanatory (...) pluralist=s general model of cross-scientific relations and discloses the valuable heuristic role hypothetical identities play in cross-scientific research. That model also supplies grounds for hesitation about the correlation objection to the psycho-physical identity theory and complaints about an explanatory gap in physicalist accounts of consciousness. These takes on psycho-neural connections miss both the sorts of considerations that motivate hypothetical identities in science and their fundamental contribution to progressive research. Thus, their focus on the contributions of research at multiple levels of analysis does not bar explanatory pluralists from considering heuristic identity theory (HIT). Arguably, it encourages it.

Extensive literatures exist on the epistemology of testimony, memory, and perception, but for the most part these literatures do not systematically consider the extent of the analogies between the three epistemic sources. A number of the same problems reappear in all three literatures, however. Dealing simultaneously with all three sources and making a careful accounting of the analogies and disanalogies between them should therefore avoid unnecessary duplication of effort. Other than limits on the scope of which memorially- and testimonially-based beliefs (...) should be included in the Parity Thesis, I argue that most of the disanalogies that different philosophers have proffered between the sources do not mark distinctions among the universes of possible testimonially-, memorially-, and perceptually-based beliefs regarding the explanation of those beliefs' epistemic status. I first criticize the suggestion that perception is a generative epistemic source, while testimony and memory are not; I propose and defend counterexamples in which testimony and memory produce new beliefs. Next, I criticize a variety of distinctions that have been drawn between testimony and perception, taken chiefly from the reductionist-antireductionist literature on testimony. I criticize the suggestion that the conceptualization of content and the transparency of experience affect the epistemologies of testimony and perception in different ways. Regarding memory and testimony, I advocate modeling testimony on the legal relationship of a principal and an agent, arguing that law's apparatus used to analyze such situations suggests that using others' epistemic services in testimony will supply the same epistemic benefits and burdens as if we had performed those epistemic tasks personally and then relied only on memory. I apply this analysis to the transmission of defeaters in testimony. I argue that memory does feature the epistemic equivalent of a perceptual image and that both perceptually- and memorially-based beliefs can concern either the past or the present. Finally, I construct a set of six transformations that turn individual possible instances of perceptually-, memorially-, or testimonially-based beliefs into individual possible instances of the other two types of beliefs without changing the structure of those beliefs' epistemologies.

Despite the remarkable advances in behavioral and brain sciences over the last decades, the mind/body (brain) problem is still an open debate and one of the most intriguing questions for both cognitive neuroscience and philosophy of mind. Traditional approaches have conceived this problem in terms of a contrast between physicalist monism and Cartesian dualism. However, since the late sixties, the landscape of philosophical views on the problem has become more varied and complex. The Multiple Realization Thesis (MRT) claims that mental (...) properties can be (or are) realized, and mental processes can be (or are) implemented by neural correlates of different kinds. Thus, MRT challenges the psychoneural type-identity theory and the corresponding reductionism. Many philosophers have acknowledged the a priori plausibility of MRT. However, the existence of empirical evidence in favor of intraspecific, human multiple realizations of mental processes and properties is still controversial. Here we illustrate some cases that provide empirical evidence in support of MRT. Recently, it has been proposed that foveal agnosic vision, like peripheral vision, can be restored by increasing object parts’ spacing (Strappini et al., 2017a; Crutch and Warrington, 2007). Agnosic fovea and normal periphery are both limited by crowding, that impairs object recognition, and provides the signature of visual integration. Here we define a psychological property of restored object identification and we cross-reference the data of visually-impaired patients with different etiologies. In particular, we compare the data of two stroke patients, two patients with posterior cortical atrophy (PCA), six cases of strabismic amblyopia, and one case with restored sight. We also compare these patients with unimpaired subjects tested in the periphery. We show that integration (i.e. restored recognition) seems to describe quite accurately the visual performance in all these cases. While the patients have different etiologies and different neural correlates, the unimpaired subjects have no neural damage. Thus similarity in the psychological property given the differences in the neural substrate can be interpreted in relation to MRT and provide evidence in its support. Finally, we will frame our contribution within the current debate concerning MRT providing new and compelling empirical evidence. (shrink)

It is a common complaint that antireductionist arguments are primarily negative. Here I describe an alternative nonreductionist epistemology based on considerations taken from multidisciplinary research in biology. The core of this framework consists in seeing investigation as coordinated around sets of problems (problem agendas) that have associated criteria of explanatory adequacy. These ideas are developed in a case study, the explanation of evolutionary innovations and novelties, which demonstrates the applicability and fruitfulness of this nonreductionist epistemological perspective. This account also bears (...) on questions of conceptual change and theory structure in philosophy of science. †To contact the author, please write to: Department of Philosophy, University of Minnesota, 831 Heller Hall, 271 19th Ave. S., Minneapolis, MN 55455; e‐mail: [email protected].

The anti-reductionist who wants to preserve the causal efficacy of mental phenomena faces several problems in regard to mental causation, i.e. mental events which cause other events, arising from her desire to accept the ontological primacy of the physical and at the same time save the special character of the mental. Psychology tries to persuade us of the former, appealing thereby to the results of experiments carried out in neurology; the latter is, however, deeply rooted in our everyday actions and (...) beliefs and despite the constant opposition of science still very much alive. Difficulties, however, arise from a combination of two claims that are widely accepted in philosophy of mind, namely, physical monism and mental realism, the acceptance of which leads us to the greatest problem of mental causation: the problem of causal exclusion. Since physical causes alone are always sufficient for physical effects mental properties are excluded from causal explanations of our behaviour, which makes them “epiphenomenal”. The article introduces Van Gulick’s solution to the exclusion problem which tries to prove that physical properties, in contrast to mental properties, do not have as much of a privileged status with respect to event causation as usually ascribed. Therefore, it makes no sense to say that physical properties are causally relevant whereas mental properties are not. This is followed by my objection to his argument for levelling mental and physical properties with respect to causation of events. I try to show that Van Gulick’s argument rests on a premise that no serious physicalist can accept. (shrink)
