Is science unified or disunified? This collection brings together contributions from prominent scholars in a variety of scientific disciplines to examine this important theoretical question. They examine whether the sciences are, or ever were, unified by a single theoretical view of nature or a methodological foundation and the implications this has for the relationship between scientific disciplines and between science and society.

Do the sciences aim to uncover the structure of nature, or are they ultimately a practical means of controlling our environment? In Instrumental Biology, or the Disunity of Science, Alexander Rosenberg argues that while physics and chemistry can develop laws that reveal the structure of natural phenomena, biology is fated to be a practical, instrumental discipline. Because of the complexity produced by natural selection, and because of the limits on human cognition, scientists are prevented from uncovering the basic (...) structure of biological phenomena. Consequently, biology and all of the disciplines that rest upon it--psychology and the other human sciences--must aim at most to provide practical tools for coping with the natural world rather than a complete theoretical understanding of it.

With this manifesto, John Dupré systematically attacks the ideal of scientific unity by showing how its underlying assumptions are at odds with the central conclusions of science itself.

As a working hypothesis for philosophy of science, the unity of science thesis has been decisively challenged in all its standard formulations; it cannot be assumed that the sciences presuppose an orderly world, that they are united by the goal of systematically describing and explaining this order, or that they rely on distinctively scientific methodologies which, properly applied, produce domain-specific results that converge on a single coherent and comprehensive system of knowledge. I first delineate the scope of arguments (...) against global unity theses. However implausible old-style global unity theses may now seem, I argue that unifying strategies of a more local and contingent nature do play an important role in scientific inquiry. This is particularly clear in archaeology where, to establish evidential claims of any kind, practitioners must exploit a range of inter-field and inter-theory connections. At the same time, the robustness of these evidential claims depends on significant disunity between the sciences from which archaeologists draw background assumptions and auxiliary hypotheses. This juxtaposition of unity with disunity poses a challenge to standard positions in the debate about scientific unity. (shrink)

In this dissertation, I investigate the recent debate about the unity, or disunity, of science and I show that some of the claims made on both sides are in need of refinement and defense. My first line of criticism concerns the legitimacy of the use of metaphysical considerations in the debate. I emphasize the often ambiguous status of antireductionist arguments and I contend that such arguments are convincing only as 'temporally qualified' arguments, whose validity depends on our state (...) of knowledge, but not as 'generally valid' arguments, that is, valid in virtue of how the world is. I also challenge the general strategy that consists in deriving metaphysical lessons from the failure of reductionism. I propose in particular an argument against Cartwright's metaphysical contention about the world being 'dappled', drawn from her attack against "horizontal" reductionism. The core of my argument is that the very notion of orderliness must be relativized to the capacities and interests of knowers. ;Another line of criticism concerns pluralist attacks against the epistemic integrity of science, which often go hand in hand with its contextualization. Charges against epistemic integrity have been developed in particular by feminist philosophers of science. I focus on one of the most worked-out and influential of these feminist standpoints: Helen Longino's contextual empiricism. I first challenge Longino's claim that cases of gender-biased science cannot be simply discarded as mere cases of "bad science" . Second, I explain why Longino's proposition for suppressing biases is too demanding and why there are serious grounds to be skeptical about its ability to serve its purpose. Finally, I propose a revised version of feminist empiricism that incorporates some of Longino's insight, and I argue for its superiority in terms of relative efficiency toward the fulfillment of the feminist agenda. ;In the concluding part of my dissertation, I investigate the relevance of the unity/disunity debate to the practice of scientists and to the authority conferred to science in our societies today.

Review of ‘Physical Theory: Method and Interpretation’ edited by Lawrence Sklar.

This book is the apologia of a frustrated reductionist. The frustration derives from Rosenberg's clear perception that the project of physicalist reduction, the reduction of all the sciences of complex objects to physics, is impossible, at least, as he often says, for beings hampered by our limited cognitive and computational abilities. The reductionism that survives this realisation is purely metaphysical. It is the firm commitment to the view that ultimately whatever happens happens because of the universally lawlike behavior of the (...) physical particles of which everything is composed. What holds these theses together is supervenience. The physical correlate of a higher level property or kind is typically massively disjunctive. Thus although the intrinsic properties of a complex thing are fully determined by the properties of the physical particles of which they are composed, the physical property necessary and sufficient to determine such a higher level property is too complex and disjunctive for our feeble minds to grasp. The underlying physical heterogeneity of the properties or kinds we distinguish at higher structural levels is such as to make it vanishingly unlikely that these will enter into the kinds of universal laws characteristic of physics or chemistry.

Reviews the book, The disorder of things: Metaphysical foundations of the disunity of science by John Dupré . The book is carefully woven around two central and interrelated theses. First is the denial that "science constitutes, or could ever come to constitute, a single, unified project," and the second is an "assertion of the extreme diversity of the contents of the world." Ultimately, Dupré wishes to contend that the second of his theses "shows the inevitability of the (...) first." Overall, Dupré seeks to refute "one particularly notorious founding metaphor of modern science, the idea that the universe should be considered as a gigantic machine." In order to accomplish such a daunting task, he engages the reader in a lengthy and critical examination of three of the philosophical theses most closely associated with the mechanistic metaphor: Essentialism, Reductionism, and Determinism. 2012 APA, all rights reserved).

There is a plurality of theoretical approaches, methodological tools, and explanatory strategies in the social sciences. Different fields rely on different methods and explanatory tools even when they study the very same phenomena. We illustrate this plurality of the social sciences with the studies of crowds. We show how three different takes on crowd phenomena—psychology, rational choice theory, and network theory—can complement one another. We conclude that social scientists are better described as researchers endowed with explanatory toolkits than specialists of (...) some specific social domain. Social scientists’ toolkits are adapted for identifying and specifying the role of specific causal factors among the multiple factors that produce social phenomena. These factors can be, in a nonexclusive way, economic incentives, psychological processes, the ecology, or aspects of the social and cultural environment. The plurality of methods and theories in the social sciences flies in the face of the project to unify the sciences associated with the positivists of the nineteenth and twentieth centuries. Yet, the compatibility and consilience of theories and practices still have epistemic value: they enable the development of more powerful and robust theories and they allow the advent of interdisciplinary studies. We present the integrative stance as the will to improve compatibility and consilience across fields, yet recognize that the plurality of causes of social phenomena invite a diversity of methodological and theoretical tools. We conclude by characterizing naturalism as an integrative stance applied to fields that belong to the social science and to the natural sciences. (shrink)

Since the 18th century, one of the key features of diagnosed psychopaths has been “moral colorblindness” or an inability to form moral judgments. However, attempts at experimentally verifying this moral incapacity have been largely unsuccessful. After reviewing the centrality of “moral colorblindness” to the study and diagnosis of psychopathy, I argue that the reason that researchers have been unable to verify that diagnosed psychopaths have an inability to make moral judgments is because their research is premised on the assumption that (...) there is a specific moral faculty of the brain, or specific “moral” emotions, and that this faculty or set of emotions can become “impaired”. I review recent research and argue that we have good reason to think that there is no such distinct capacity for moral judgment, and that, as a result, it is impossible for someone’s “moral judgment faculty” to become selectively disabled. I then discuss the implications of such a position on psychopathy research, the coherence of the disorder, and the moral responsibility of psychopaths. (shrink)

It is commonplace for both philosophers and cognitive scientists to express their allegiance to the "unity of consciousness". This is the claim that a subject’s phenomenal consciousness, at any one moment in time, is a single thing. This view has had a major influence on computational theories of consciousness. In particular, what we call single-track theories dominate the literature, theories which contend that our conscious experience is the result of a single consciousness-making process or mechanism in the brain. We argue (...) that the orthodox view is quite wrong: phenomenal experience is not a unity, in the sense of being a single thing at each instant. It is a multiplicity, an aggregate of phenomenal elements, each of which is the product of a distinct consciousness-making mechanism in the brain. Consequently, cognitive science is in need of a multi-track theory of consciousness; a computational model that acknowledges both the manifold nature of experience, and its distributed neural basis.

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

A central theme of the unified framework for addiction advanced by Redish et al. is that there exists a common value or incentive process controlling Pavlovian and instrumental conditioning. Here we briefly review evidence from a variety of sources demonstrating that these incentive processes are in fact independent. Clearly the influence of Pavlovian predictors and goal values on choice offer distinct potential targets for pathologies of decision-making.

Pragmatism is usually viewed as a unifed school, movement or tradition. Lists of its most important tenets typically include advocacy of open inquiry, pursued with an awareness of human fallibility, a view of justifcation that appeals to shared experience in all its manifestations – aesthetic, religious, moral, political and scientifc – and a conception of philosophy as a practice interwoven with problems of contemporary life. While disagreements among pragmatists are widely acknowledged, they are most often treated as easily resolved or (...) of marginal importance given the substantial body of doctrine that pragmatists are thought to share. I argue that this view of pragmatism obscures important philosophical differences among its proponents, to the serious detriment of our understanding of the tradition. I point out that fgures most often credited with advancing pragmatism – Charles Peirce, William James, John Dewey, W.V. Quine, Hilary Putnam and Richard Rorty – defend signifcantly divergent views, views that are anything but easy to reconcile. Their differences go to the very heart of how pragmatism is to be understood and defended and present serious obstacles to any characterization of it as a tradition with a common philosophical method, purpose or core set of doctrines. Pragmatism is far more diverse, subtle and diffcult to come to terms with than contemporary accounts of what is living and dead in it commonly presume. (shrink)

Abstract According to John Dupré, the metaphysics underpinning modern science posits a deterministic, fully law?governed and potentially fully intelligible structure that pervades the entire universe. To reject such a metaphysical framework for science is to subscribe to ?the disorder of things?, and the latter, according to Dupré, entails the impossibility of a unified science. Dupré's argument rests crucially upon purported disunities evident in the explanatory practices of science. I critically examine the implied project of drawing metaphysical (...) conclusions from epistemological premisses concerning the nature of our explanatory practices. I then argue that Dupré fails to answer a particular argument for the ontological unity of science that rests upon assumptions about the causal structure of the world. This ?causal? argument for the unity of science might be countered by a more radical metaphysical revisionism. The latter, however, seems unable to account for features of our explanatory practices that testify to a measure of explanatory unity in science. I conclude by sketching a strategy that might enable the revisionist to overcome such difficulties. (shrink)

Effective agency, according to contemporary Kantians, requires a unity of purpose both at a time, in order that we may eliminate conflict among our motives, and over time, because many of the things we do form part of longer-term projects and make sense only in the light of these projects and life plans. Call this the unity of agency thesis. This thesis can be regarded as a normative constraint on accounts of personal identity and indeed on accounts of what it (...) is to have the life of a person in the broad, rather than narrowly biological sense. It is also a fundamental condition of social life that persons within society fulfill a range of longitudinal roles: parenthood is one such obvious example, as are teachers, health professionals, engineers, artists, and many others. The fulfillment of these and other valuable social roles requires that agents have the capacity to rationally conceive of themselves as engaged in these roles and subject to the demands of them. To be unable to fulfill any such longitudinal social roles is to have a life deficient in value. The unity of agency is thus, we argue, something we rationally strive for, and something to be morally promoted. Psychiatric states that undermine the unity of agency are morally and rationally disvaluable. Using the example of dissociation, we explain how one such state may have this undermining or disruptive effect on the unity of agency. The therapeutic ends for psychiatry in conditions involving such states are thus seen more globally as the restoration of effective agency, that is, unified agency. (shrink)

It is widely supposed that the scientists in any field use identical standards for evaluating theories. Without such unity of standards, consensus about scientific theories is supposedly unintelligible. However, the hypothesis of uniform standards can explain neither scientific disagreement nor scientific innovation. This paper seeks to show how the presumption of divergent standards (when linked to a hypothesis of dominance) can explain agreement, disagreement and innovation. By way of illustrating how a rational community with divergent standards can encourage innovation and (...) eventually reach consensus, recent developments in geophysics are discussed at some length.

This thesis examines the claim that the sciences are disunified. Chapter 1 outlines and introduces different accounts of the stratification of the sciences in the literature, in particular, Unificationism, Disunificationism, Eliminativism and Human Science Disunificationism. I argue that all of these competing views are informed by an ideal model for successful science. In particular, all of the views discussed are committed to the claim that a science requires laws to be considered scientifically legitimate. At the end of (...) this chapter, the narrower topic of the thesis is revealed: do the special sciences have real legitimate ceteris paribus laws? (shrink)

Kammerer and Frankish (this issue) challenge us to expand our conception of introspection beyond neurotypical human cases. This article describes a possible 'ancillary mind' modelled on a system envisioned in Leckie's (2013) science fiction novel Ancillary Justice. The ancillary mind constitutes a borderline case between a communicating group of individuals and a single, spatially distributed mind. It occupies a grey zone with respect to personal identity and subject individuation, neither determinately one person or subject nor determinately many persons or (...) subjects, and thus some of its processes might be neither determinately introspection within a mind nor determinately communication between minds. If ancillary minds defy discrete countability, the same might be true for some actual minds on Earth. Kammerer and Frankish's research programme can be extended to include not only the study of possible forms of introspection, but also the study of possible mental activity intermediate between introspection and communication.
