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)

The Unity of Science is often thought to be reductionist, but this is because we fail to distinguish questions from answers. The questions asked by different sciences are different---the biologist is interested in different topics from the physicist, and seeks different explanations---but the answers are not peculiar to each particular science, and can range over the whole of scientific knowledge. The biologist is interested in organisms--- concept unknown to physics---but explains physiological processes in terms of chemistry, not (...) a mysterious vital force. The replacement of Laplacian determinism by quantum mechanics further erodes the tendency towards reductionism. The answers given in different explanations are not subsumed under one complete theory; and quantum mechanics does not have a concept of haecceitas, "this-i-ness" which would make its entities the fundamental constituents of everything.

The present thesis explores some metaphysical issues concerning biochemical kinds and the relations between chemical and biological properties and phenomena. The main result of this thesis is that there is something sui generis about biochemical kinds. This result is motivated by two theoretical steps. The first is characterising biochemical functions as weakly emergent from the chemical structure [Chapter 3, Chapter 6]. The second is via an account for which biochemical kinds are natural categories [Chapter 4, Chapter 7]. The thesis comprises (...) four parts. Part I [Chapter 1, Chapter 2] aims to offer the methodological and conceptual tools that underpin this research. Chapter 1 presents the debate on the unity of science and the motivation of the research. Chapter 2 presents the account of natural kinds that will be used throughout the thesis. Part II [Chapter 3, Chapter 4] offers a detailed metaphysical analysis of the molecular gene. Chapter 3 argues that molecular genes are weakly emergent from nucleic acids. Chapter 4 argues that the category "molecular gene" can be deemed a natural kind, following the account presented in Chapter 2. Part III [Chapter 5, Chapter 6, Chapter 7] explores some of the themes related to biochemical kinds and generalises some of the results from Part II. Chapter 5 considers biochemical functions and how functional attribution should be interpreted for biochemical molecules. Chapter 6 considers the relation between biochemical functions and structure, spelt in terms of weak emergence and explores unity in biochemistry. Chapter 7 considers the topic of biochemical kinds per se and argues that biochemical kinds are natural categories. Part IV [Chapter 8] elucidates the main outcome and the implications that this research can have for future discussion in the philosophy and metaphysics of biochemistry and the unity of science.

Among the most promising options for vindicating Oppenheim and Putnam’s unity of science hypothesis is the ‘Mentaculus’ of Albert and Loewer. I assess whether this promise can be borne out. My focus is on whether the Mentaculus can deliver what Oppenheim and Putnam call the ‘unity of laws’: the reduction of special science laws to the laws of fundamental physics. I conclude that although the Mentaculus may support a fairly strong form of reductionism, it falls short (...) of upholding the unity of laws. (shrink)

the demise of the logical positivism programme. The answers given to these qu- tions have deepened the already existing gap between philosophy and the history and practice of science. While the positivists argued for a spontaneous, steady and continuous growth of scientific knowledge the post-positivists make a strong case for a fundamental discontinuity in the development of science which can only be explained by extrascientific factors. The political, social and cultural environment, the argument goes on, determine both the (...) questions and the terms in which they should be answered. Accordingly, the sociological and historical interpretation - volves in fact two kinds of discontinuity which are closely related: the discontinuity of science as such and the discontinuity of the more inclusive political and social context of its development. More precisely it explains the discontinuity of the former by the discontinuity of the latter subordinating in effect the history of science to the wider political and social history. The underlying idea is that each historical and - cial context generates scientific and philosophical questions of its own. From this point of view the question surrounding the nature of knowledge and its development are entirely new topics typical of the twentieth-century social context reflecting both the level and the scale of the development of science.

As a leading member of the Vienna Circle, Rudolph Carnap's aim was to bring about a "unified science" by applying a method of logical analysis to the empirical data of all the sciences. This work, first published in English in 1934, endeavors to work out a way in which the observation statements required for verification are not private to the observer. The work shows the strong influence of Wittgenstein, Russell, and Frege.

This unique overview of natural phenomena and foundations of different technologies (chemistry, electronics, optics, etc.). explores the connections and unified foundations of diverse scientific and technological fields. Requiring knowledge of linear algebra and calculus, it is ideal for students of chemistry, material sciences and engineering.

The aim of the series Logic, Epistemology, and the Unity of Science, of which this is the first volume, is to take up anew the challenge of considering the ...

ABSTRACTThis paper elaborates a conception of the unity of science that emerges in the context of Dilthey’s well-known treatment of the distinction between the Naturwissenschaften and the Geisteswissenschaften. Dilthey’s account of the epistemological foundations of the Geisteswissenschaften presupposes, this paper argues, their continuity with the natural sciences. The unity of the two domains has both a psychological and a biological basis. Whereas the psychological functions at work in scientific thinking, the articulation of which is the task of (...) Dilthey’s proposed science of ‘descriptive and analytic psychology’, are common to both kinds of sciences, their ontological ground consists in the embodied and environmentally situated context of human beings, and is expressed in Dilthey’s central concept of ‘life’. Accordingly, this paper develops the shared biopsychological foundations of the epistemology of the natural and human sciences from Dilthey’s writings in the 1880s and 1890s. Dilthey’s conception of unity, furthermore, has implications for philosophy’s orientation towards the special sciences. Thus, in conclusion, this paper applies the biopsychological account to sketch an outline of Dilthey’s historicist method in the philosophy of science, and considers its similarities and differences with a contemporary approach in ‘historical epistemology’.

The paper addresses the question of how the unity of science can adequately be characterized. A mere classification of scientific fields and disciplines does not express the unity of science unless it is supplemented with a perspective that establishes a systematic coherence among the different branches of science. Four ideas of this kind are discussed. Namely, the unity of scientific language, of scientific laws, of scientific method and of science as a practical‐operational enterprise. (...) Whereas reference to the unity of scientific language and of scientific laws does not provide a viable basis for the unity of science, the methodological and practical unity might. The unity of science can be characterized by the way in which methodological criteria enter into the assessment or evaluation of theories, and, moreover, by a transdisciplin‐ary approach to problems. Accordingly, the unity of science is not expressed by theoretical uniformity but by the unity of scientific practice. (shrink)

Science is a dynamic process in which the assimilation of new phenomena, perspectives, and hypotheses into the scientific corpus takes place slowly. The apparent disunity of the sciences is the unavoidable consequence of this gradual integration process. Some thinkers label this dynamical circumstance a ‘crisis’. However, a retrospective view of the practical results of the scientific enterprise and of science itself, grants us a clear view of the unity of the human knowledge seeking enterprise. This book provides (...) many arguments, case studies and examples in favor of the unity of science. These contributions touch upon various scientific perspectives and disciplines such as: Physics, Computer Science, Biology, Neuroscience, Cognitive Psychology, and Economics. (shrink)

It has been maintained, by both philosophers and modern scientists, that the two domains of discourse of science and of philosophy are disjoint Though admitting that many physicists subscribed to metaphysical principles, it was claimed - by Duhem and Reichenbach among others - that the scientist's philosophical convictions play, or should play, no role in his scientific work. The present paper attempts to refute this separatist view by showing that Einstein's metaphysical realism - coupled with his Platonistic panmathematicism - (...) played a crucial role in his construction of the Relativity Programme and in his criticism of Quantum Mechanics. The article also shows that although Einstein was neither a strict Humean nor a strict Machian, his phenomenalist interpretation of the empirical basis proved to be an antidote against both conventionalist scepticism and Neurath's coherence theory of truth. /// Tanto filósofos como cientistas têm defendido a ideia de que os domínios discursivos da Ciência e da Filosofia seguem caminhos separados. Mesmo admitindo que muitos cientistas subscreveram princípios metafísicos, a ideia tem sido defendida - por Duhem e Reichenbach, entre outros - de que as convicções filosóficas do cientista não desempenham, ou deveriam não desempenhar, qualquer papel no seu trabalho científico. O objectivo do presente artigo é refutar esta visão separatista das coisas mostrando de que modo o realismo metafísico de Einstein - associado ao seu panmatematicismo platónico - desempenhou um papel crucial na sua construção do Programa da Relatividade e nas suas críticas à Mecânica Quântica. O artigo mostra igualmente que embora Einstein não fosse nem um Humeano estrito nem um estrito Macheano, a sua interpretação fenomenalista da base empírica demonstrou ser um antídoto quer contra o cepticismo convencionalista quer contra a teoria da coerência da verdade de Neurath.

An historically important conception of the unity of science is explanatory reductionism, according to which the unity of science is achieved by explaining all laws of science in terms of their connection to microphysical law. There is, however, a separate tradition that advocates the unity of science. According to that tradition, the unity of science consists of the coordination of diverse fields of science, none of which is taken to have (...) privileged epistemic status. This alternate conception has roots in Otto Neurath’s notion of unified science. In this paper, I develop a version of the coordination approach to unity that is inspired by Neurath’s views. The resulting conception of the unity of science achieves aims similar to those of explanatory reductionism, but does so in a radically different way. As a result, it is immune to the criticisms facing explanatory reductionism. This conception of unity is also importantly different from the view that science is disunified, and I conclude by demonstrating how it accords better with scientific practice than do conceptions of the disunity of science.

We live together in one natural, if complex, world, and our scientific knowledge of it ought to be correspondingly unified. But currently the sciences collectively form a very complex structure, partly interrelated, partly unrelated, and partly incompatible. How is this condition explained, and what may we expect of unity in science?

It is no secret that various versions of logical empiricism argued for the importance of unified science. Carnap was a proponent of unity of science views, although he expressed this in different idioms at different times. In the Aufbau (1928) he spoke of the unity of the object domain secured through definability in the constitutional system, in his physicalist period he argued that a physicalist language could serve as the universal language of science, and in (...) his mature philosophical work he investigated a variety of meanings that might be attached to reductionist projects for unifying various scientific fields. Our essay focuses less on Carnap’s several proposals than on a prior interpretive question: what was philosophically at stake for Carnap in the question of the unity of science? We begin with some suggestions in Carnap’s 1963 Intellectual Autobiography, where he calls unity of science “one of the main tenets of our general philosophical conception” and one in which Neurath’s emphasis on the “interdependence of all decisions … made a strong impression” on him. We follow Carnap in the suggestion that an account of his approach to unity of science does not take us into questions of unity of nature but rather of the scientific attitude and the unity of reason.

During the last three decades, there has been a growing realization among physicists and cosmologists that the relation between particle physics and cosmology may constitute yet another successful example of the unity of science. However, there are important conceptual problems in the unification of the two disciplines, e.g. in connection with the cosmological constant and the conjecture of inflation. The present article will outline some of these problems, and argue that the victory for the unity of (...) class='Hi'>science in the context of cosmology and particle physics is still far from obvious.

Open peer commentary on the article “Second-Order Science: Logic, Strategies, Methods” by Stuart A. Umpleby. Upshot: Umpleby’s target article is important for bridging the gap between the natural and social sciences. While I agree with his claims, his proposals may not reach far enough. Concrete methods of empirical research, which are of crucial importance for a breakthrough, deserve further elaboration.

Modem science and technology tend to create one global civilization. To what extent and how can cultural pluralism be preserved under these conditions? Neither inherent limitations of natural science and technology nor alternative lines of developing them offer a promising road for pluralism. But it is to be expected that the unifying trend will not carry over into the realm of the human and social sciences; these are rather to be construed as "locally dispersed", i.e. uncapable of being (...) developed into a unified theory of human nature, whereas natural science refers to a unified picture of non-human nature. Thus, modest hopes for preserving pluralism seem to be justified. (shrink)

The aim of this book is both to develop a logic of microreduction, primarily for dynamic theories, or theories that state and explain the attributes and behavior, rather than the evolutionary development, of the things in some domain and, also, to argue that a program of microreduction offers the best hope for the unification of science. After two initial chapters, developing the necessary logical tools and techniques, Causey gets to the central problem of microreduction. The fundamental idea is: a (...) theory, T2, involving entities and attributes proper to some domain, D2, is microreduced to a theory, T1, involving entities and attributes proper to some other domain, D1, when the entities of D2 are explained as structured wholes made up of elements of D1. Attributes present more of a problem. One must first select the classifying attributes which divide the entities of each domain into disjoint equivalence classes. The connecting sentences, relating attributes of D2 to attributes of D1 cannot be identity statements in a set-theoretic formulation but should be such in a more flexible formulation. On this basis, the author gives a detailed specification of the condition for a successful, i.e., no emergence, reduction of the ontology and laws of T2 to those of T1. The second half of the book is more programmatic defending the program of microreduction as the best, though presently unrealizable, means of unifying science. The objections to the program brought by Fodor and others are countered. Though the author’s detailed analysis is geared to the reduction of chemistry to physics, he believes that the same general method should also handle the reduction of social sciences to a science of individual behavior.

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)
