Im Zentrum dieses Bandes stehen die Beiträge einer Tagung, die im Oktober 2017 an der Universität Konstanz stattgefunden hat. Thema der Tagung war ein den historischen Kontext einbeziehender Blick auf den frühen Rudolf Carnap, vom Ende des Ersten Weltkriegs bis zur Emigration Ende 1935. Der 1891 in Ronsdorf bei Wuppertal geborene Rudolf Carnap entschloss sich erst relativ spät zu einer Karriere als akademischer Philosoph, nämlich 1920, nachdem er sein durch den Krieg unterbrochenes Studium der Physik und Philosophie in Jena und (...) Freiburg abgeschlossen und kurze Zeit überlegt hatte, als Lehrer in der Schulreform-Bewegung zu arbeiten. Es folgte die philosophische Promotion im Jahr 1921, bei Bruno Bauch in Jena, mit einer Doktorarbeit zum Raumproblem. 1923 organisierte Carnap, gemeinsam mit Hans Reichenbach und anderen, eine für die Entstehung des Logischen Empirismus bedeutsame kleine Tagung in Erlangen. Auf Einladung von Moritz Schlick habilitierte er sich 1926 an der Universität Wien und verbrachte die Zeit bis 1931 zumindest teilweise in Wien, als eines der Kernmitglieder des Wiener Kreises um Moritz Schlick. Seine Habilitationsschrift erschien 1928 unter dem Titel Der logische Aufbau der Welt (hier immer Aufbau). 1931 folgte Carnap einem Ruf an die Deutsche Universität Prag. In den darauffolgenden Jahren blieb aber der enge Kontakt mit Wien und dem Wiener Kreis erhalten. Carnaps hauptsächliche Arbeit in dieser Zeit war seinem zweiten großen Buchprojekt gewidmet, der 1934 publizierten Logischen Syntax der Sprache. Daneben verfasste Carnap in seiner Zeit in Wien und Prag auch zahlreiche Aufsätze, zu unterschiedlichen Aspekten der Logik, der Metaphysikkritik und der Wissenschaftstheorie. Er war Mitautor des Manifests Wissenschaftliche Weltauffassung: Der Wiener Kreis und nahm regen Anteil an den zahlreichen wissenschaftlichen Aktivitäten des Logischen Empirismus, von der Gründung der Zeitschrift Erkenntnis bis hin zum Projekt einer Enzyklopädie der Einheitswissenschaft. Spätestens ab 1933 musste Carnap jedoch feststellen, dass an eine weitere wissenschaftliche Karriere in dem von Faschismus und Nationalsozialismus geprägten politischen Klima in Kontinentaleuropa nicht zu denken war. Er strebte deshalb die Emigration ins englischsprachige Ausland an, die schließlich Ende 1935 gelang, als Carnap ein Angebot von der Universität Chicago erhielt. Obwohl Carnap nur den kleineren Teil der in diesem Band abgedeckten eineinhalb Jahrzehnte in Wien verbracht hat, widmet sich der Großteil der hier versammelten Beiträge schwerpunktmäßig der für Carnaps philosophische Karriere zentralen Wiener Zeit.

ABSTRACT Neurath’s scientific utopianism is the proposal that the social sciences should engage in the elaboration, development, and comparison of counterfactual scenarios, the ‘utopias’. Such scenarios can be understood as centerpieces of scientific thought experiments, that is, in exercises of imagination that not only promote conceptual revision, but also stimulate creativity to deal with experienced problems, as utopias are efforts to imagine what the future could look like. Moreover, utopian thought experiments can offer scientific knowledge to inform political debates and (...) decisions, contributing to the shaping of society. This essay reconstructs a historical event as an example of Neurath’s utopianist methodology. In the late 1970s and early 1980s, a scientific and political commission appointed by the Western German Parliament devised and compared four scenarios for future energetic-economic policies. Conclusions of the commission informed political decisions that put Western (later reunified) Germany in a route towards becoming a green industrial power. A fundamental part of the commission’s work involved an appeal to imagination, allowing for the characterization under Neurath’s methodology. (shrink)

A. J. Ayer’s Language, Truth, and Logic had been responsible for introducing the Vienna Circle’s ideas, developed within a Germanophone framework, to an Anglophone readership. Inevitably, this migration from one context to another resulted in the alteration of some of the concepts being transmitted. Such alterations have served to facilitate a number of false impressions of Logical Empiricism from which recent scholarship still tries to recover. In this paper, I will attempt to point to the ways in which LTL has (...) helped to foster the various mistaken stereotypes about Logical Empiricism which were combined into the received view. I will begin by examining Ayer’s all too brief presentation of an Anglocentric lineage for his ideas. This lineage, as we shall see, simply omits the major 19th century Germanophone influences on the rise of analytic philosophy. The Germanophone ideas he presents are selectively introduced into an Anglophone context, and directed towards various concerns that arose within that context. I will focus on the differences between Carnap’s version of the overcoming of metaphysics, and Ayer’s reconfiguration into what he calls the elimination of metaphysics. Having discussed the above, I will very briefly outline the consequences that Ayer’s radicalisation of the Vienna Circle’s doctrines had on the subsequent Anglophone reception of Logical Empiricism.

According to the article, Neurath's reflexive epistemology—expressed by the metaphor of the ship in need of reconstruction on the open sea—represents a philosophical alternative to the classical and contemporary forms of scientific realism and ethical cognitivism, including Popper's falsificationism. Against Quine's reductive interpretation of Neurath's boat argument as the basis for a 'naturalized epistemology,' the article maintains that the metaphor suggests the idea of an insuperable situation of linguistic and conceptual circularity. This prevents any attempt at self-foundation in scientific knowledge, (...) as well as in ethics and politics, and rules out any 'constructive philosophy' aiming to break circularity in pursuit of some methodological beginning.

Traditionally, the proponents of empiricism sought for the starting point of knowledge in sensations that happen to us when we open our sense organs to the world. They analyzed the functioning of human faculties of sensation and cognition and the way these faculties are activated so as to discover the origin of ideas. Thus, they insisted on the priority of particulars to universals in the body of synthetic knowledge, and granted empirical facts the authority of truth. For that reason, they (...) are opposed to the rationalists, who maintained that the most important part of synthetic knowledge is derived solely from first principles or ideas, and that these principles or ideas are “innate”—that reason can ascertain their truth intuitively without the use of the senses.Logical positivism belongs to the empiricist tradition. However, it distinguishes itself from its empiricist predecessors in a very important way, so that its proponents thought they could overcome the difficulties raised against the older empiricists.

This paper reconstructs the American reception of logical positivism in the early 1930s. I argue that Moritz Schlick (who had visiting positions at Stanford and Berkeley between 1929 and 1932) and Herbert Feigl (who visited Harvard in the 1930-31 academic year) played a crucial role in promoting the *Wissenschaftliche Weltauffassung*, years before members of the Vienna Circle, the Berlin Group, and the Lvov-Warsaw school would seek refuge in the United States. Building on archive material from the Wiener Kreis Archiv, the (...) Harvard University Archives, and the Herbert Feigl Papers, as well as a large number of publications in American philosophy journals from the early 1930s, I reconstruct the subtle transformation of the American philosophical landscape in the years immediately preceding the European exodus. I argue that (1) American philosophical discussions about meaning and significance and (2) internal dynamics in the Vienna Circle between 1929 and 1931 significantly impacted the way in which US philosophers came to perceive logical positivism.

European Journal of Philosophy, EarlyView.

This paper investigates how the doctrine of the epistemological given—long associated with empiricism and positivism and also informing Carnap’s first major work in 1928—was challenged and overcome by Neurath and Carnap in subsequent years. Particular attention is paid to the controversial issue of how precisely the dialectic between Neurath and Carnap played out: whether Neurath’s argumentation correctly engaged with Carnap’s actual positions, whether Carnap’s change of positions in turn fully engaged with Neurath’s challenge, and what all this may tell us (...) about the compatibility of their philosophical projects.

Carnap’s lectures at the 1935 Paris Congress for the Unity of Science marked the beginning of his mature metaphilosophy. This paper considers what role remained for epistemology once it was “purified” of all psychological elements as Carnap there demanded. It is argued that while this did mean the end of traditional epistemology, room was found for nontraditional versions in the course of the further development of Carnap’s logic of science.

This paper responds to a recent criticism of Uebel's analysis of Neurath's protocol statements and proposes some independent amendments.

ABSTRACT Arne Naess once called himself ?a kind of metaphysician?: did or did he not therewith turn his back on his philosophical mentors in the Vienna Circle? To try to determine the meaning of this self-ascription, this paper first considers in detail two works in which his disagreements with the philosophers of the Vienna Circle found their clearest and most detailed expression. Concentrating on Carnap it will be argued that while some of Naess's criticisms cannot be taken as authoritative, he (...) did indicate a clear dividing line between himself and Carnap. Turning then to Naess's valediction to philosophy of science from 1972, Naess's appreciation of the role of metaphysics for science will be discussed and compared with his appreciation for the role of metaphysics for personal and political life as expressed in his still later ecophilosophy. Once allowance is made for the different needs addressed by his writings for the deep ecology movement and a certain 1960s' rhetoric is discounted as no longer appropriate, it can be seen that Naess's theoretical philosophy exhibited a remarkable continuity throughout.

The cognitive critique of the goals and desires that are input into the implicit calculations that result in instrumental rationality is one aspect of what has been termed broad rationality (Elster, 1983). This cognitive critique involves, among other things, the search for rational integration (Nozick, 1993)—that is, consistency between first-order and second-order preferences. Forming a second-order preference involves metarepresentational abilities made possible by mental decoupling operations. However, these decoupling abilities are separable from the motive that initiates the cognitive critique itself. (...) I argue that Velleman (1992) has identified that motive (“the desire to act in accordance with reasons”), and that it might be operationalisable as a thinking disposition at a very superordinate cognitive level. This thinking disposition, the Master Rationality Motive, is likely to be of particular importance in explaining individual differences in the tendency to seek rational integration. Preliminary research on related constructs suggests that this construct is measurable. (shrink)

Several recent works in history and philosophy of science have re-evaluated the alleged opposition between the theses put forth by logical empiricists such as Carnap and the so-called "post-positivists", such as Kuhn. Although the latter came to be viewed as having seriously challenged the logical positivist views of science, recent authors maintain that some of the most notable theses of the Kuhnian view of science have striking similarities with some aspects of Carnap's philosophy. Against that reading, Oliveira and Psillos argue (...) that within Carnap's philosophy there is no place for the Kuhnian theses of incommensurability, holism, and theory-ladenness of observations. This paper presents each of those readings and argues that Carnap and Kuhn have non-opposing views on holism, incommensurability, the theory-ladenness of observations, and scientific revolutions. We note at the very end - without dwelling on the point, however - that they come apart on other matters, such as their views on metaphysics and on the context of discovery/justification distinction.

The purpose of this note is to examine the relationship between the practice of mathematics and the philosophy of mathematics, ontology in particular. One conclusion is that the enterprises are (or should be) closely related, with neither one dominating the other. One cannot 'read off' the correct way to do mathematics from the true ontology, for example, nor can one ‘read off’ the true ontology from mathematics as practiced.

How mathematicians conceive of the nature of mathematics is reflected in the metaphors they use to talk about it. In this paper I investigate a change in the use of metaphors in the late nineteenth and early twentieth centuries. In particular, I argue that the metaphor of mathematics as a tree was used systematically by Pasch and some of his contemporaries, while that of mathematics as a building was deliberately chosen by Hilbert to reflect a different view of mathematics. By (...) taking these metaphors seriously we attain a new vantage point for understanding historical changes in conceptions of mathematics. (shrink)

Over the past twenty years, Husserlian phenomenology has increasingly drawn the attention of the cognitive community, thereby leading to the emergence of what might be called a phenomenological trend within contemporary cognitive studies. What this phenomenological trend really amounts to is however a matter of debate. The reason is that it embodies, in fact, a multifaceted reflection about the relevance of Husserlian phenomenology to the current efforts towards a scientific theory of cognition, and, to a lesser degree, about the reciprocal (...) relevance of these efforts to the fate of the Husserlian tradition. Indeed, it covers a wide array of perspectives on these questions, ranging from tentative demonstrations of the cognitively misleading character of Husserl's ideas, inasmuch as they would incarnate the same foundational errors as cognitivism (Hall and Dreyfus 1982), to diametrically opposed views arguing that the naturalist bent of contemporary cognitive science is ill-conceived, and that only the brand of transcendentalism defended by Husserl can provide it with adequate foundations (cf., for instance, Villela-Petit 1999).

The present article purports to show that the protocol sentence debate, pursued by some leading members of the Vienna Circle in the mid-1930s, was essentially a controversy over the explanation and the real significance of the concept of truth. It is further shown that the fundamental issue underlying the discussions about the concept of truth was the relationship between form and content, as well as between logic/language and the world. R. Carnap was the philosopher who most explicitly and systematically attempted (...) to come to grips with this problem. It is shown that the form-content distinction pervades the three most important phases of Carnap's philosophical development: the structuralist (in Der logische Aufbau der Welt), the syntactical and the semantical. His final semantical stance is essentially determined by the concept of linguistic frameworks. The article purports to demonstrate that this concept cannot be dispensed with in philosophy, but that Carnap failed to work out its ontological implications. Finally, the concept of an internal ontology is briefly delineated. (shrink)

It is a widespread intuition that the coherence of independent reports provides a powerful reason to believe that the reports are true. Formal results by Huemer, M. 1997. “Probability and Coherence Justification.” Southern Journal of Philosophy 35: 463–72, Olsson, E. 2002. “What is the Problem of Coherence and Truth?” Journal of Philosophy XCIX : 246–72, Olsson, E. 2005. Against Coherence: Truth, Probability, and Justification. Oxford University Press., Bovens, L., and S. Hartmann. 2003. Bayesian Epistemology. Oxford University Press, prove that, under (...) certain conditions, coherence cannot increase the probability of the target claim. These formal results, known as ‘the impossibility theorems’ have been widely discussed in the literature. They are taken to have significant epistemic upshot. In particular, they are taken to show that reports must first individually confirm the target claim before the coherence of multiple reports offers any positive confirmation. In this paper, I dispute this epistemic interpretation. The impossibility theorems are consistent with the idea that the coherence of independent reports provides a powerful reason to believe that the reports are true even if the reports do not individually confirm prior to coherence. Once we see that the formal discoveries do not have this implication, we can recover a model of coherence justification consistent with Bayesianism and these results. This paper, thus, seeks to turn the tide of the negative findings for coherence reasoning by defending coherence as a unique source of confirmation. (shrink)

Starting from a suggestion of Stephen Toulmin and through an interpretation of the criticism to which Neurath, one of the founders of the Vienna Circle, submits Descartes’ views on science, the paper attempts to outline a pattern of modernity opposed to the Cartesian one, that has been obtaining over the last four centuries. In particular, it is argued that a new alliance has to be established between science and education, overcoming Descartes’ banishment against education. In a Neurathian perspective education is (...) a key-moment of the scientific enterprise without which science itself is in danger of going astray and no scientific outlook is promoted in the society at large. Such an anti-Cartesian attitude is a leitmotiv of the whole Neurath’s production and characterizes his fundamental approach to the sense of modernity. For this reasons, despite all its shortcomings, Neurath’s proposal represents a very promising option for a new agenda of the modernity away from Descartes’ spell. By elaborating on Neurath’s (and Dewey’s) insights, the paper puts forward the idea that philosophy of science (such as it was originated by neopositivism in its Reichenbachian version) should give way to an educational philosophy of science which could allow us “to bring the genuine modern into existence”.

This article considers the evolution of Feigl's attempt at establishing a stable form of scientific realism. I will argue that Feigl's work in that area should be appreciated for two reasons: it represents a telling case against the view of there being an unbridgeable ‘analytic-continental divide’ in the context of twentieth-century philosophy; it contradicts the idea that scientific realism is at odds with logical empiricism. It will be shown that Feigl developed his scientific realist position from within the logical empiricists’ (...) Vienna Circle. This, in turn, necessitates a fresh approach toward the contemporary scientific realism debate. (shrink)

In this dialogue the view of Paul Hoyningen-Huene as defended in Systematicity. The Nature of Science is presented and criticized. The approach is developed dialectically by the two interlocutors, a series of critical points are debated and an alternative view is introduced. The dialogical form is intended to honor the general philosophical approach of the author summarized in the last sentence of the book, where he states that he sees philosophy as an ongoing, open-ended dialogue.

Syntactic approaches in the philosophy of science, which are based on formalizations in predicate logic, are often considered in principle inferior to semantic approaches, which are based on formalizations with the help of structures. To compare the two kinds of approach, I identify some ambiguities in common semantic accounts and explicate the concept of a structure in a way that avoids hidden references to a specific vocabulary. From there, I argue that contrary to common opinion (i) unintended models do not (...) pose a significant problem for syntactic approaches to scientific theories, (ii) syntactic approaches can be at least as language-independent as semantic ones, and (iii) in syntactic approaches, scientific theories can be as well connected to the world as in semantic ones. Based on these results, I argue that syntactic and semantic approaches fare equally well when it comes to (iv) ease of application, (v) accommodating the use of models in the sciences, and (vi) capturing the theory-observation relation.

Carnap’s search for a criterion of empirical significance is usually considered a failure. I argue that the results from two out of his three different approaches are at the very least problematic, but that one approach led to success. Carnap’s criterion of translatability into logical syntax is too vague to allow for definite results. His criteria for terms—introducibility by chains of reduction sentences and his criterion from “The Methodological Character of Theoretical Concepts”—are almost trivial and have no clear relation to (...) the empirical significance of sentences. However, his criteria for sentences—translatability, verifiability, falsifiability, confirmability—are usable, and under the assumptions needed for the Carnap sentence approach, verifiability, falsifiability, and translatability become equivalent. As a result of the Carnap sentence approach, metaphysics is rendered analytic. (shrink)

Science depends on judgments of the bearing of evidence on theory. Scientists must judge whether an observation or the result of an experiment supports, disconfirms, or is simply irrelevant to a given hypothesis. Similarly, scientists may judge that, given all the available evidence, a hypothesis ought to be accepted as correct or nearly so, rejected as false, or neither. Occasionally, these evidential judgments can be made on deductive grounds. If an experimental result strictly contradicts a hypothesis, then the truth of (...) the data deductively entails the falsity of the hypothesis. In the great majority of cases, however, the connection between evidence and hypothesis is non-demonstrative, or inductive. In particular, this is so whenever a general hypothesis is inferred to be correct on the basis of the available data, since the truth of the data will not deductively entail the truth of the hypothesis. It always remains possible that the hypothesis is false even though the data are correct. (shrink)

Foundationalism came under attack in two areas in the first half of this century. First, some doubted whether the foundations were adequate to support the entire structure of knowledge, and second, the doctrine of the Agiven@ came under serious attack. = However, many epistemologists were not convinced that foundationalism was to be abandoned even if the criticisms were granted. According to these epistemologist, far from having shown that foundationalism itself was at fault, the critics of foundationalism had only been attacking (...) one particular version of foundationalism--that version that included infallibility, incorrigibility,, or some appeal to a Agiven@ at the base of the structure of justification. The claim of these defenders was that there are other possible types of foundationalism than this version of foundationalism, which has come to be called Classical Foundationalism. And thus opened up a new area of philosophical lexicography: the attempt to say what foundationalism itself is, so that Classical Foundationalism turned out to be one instance of foundationalism but not the only possible one.

Philosophy of the Art of Science. Historical Remarks on the Significance of Rules in Scientific Language. This paper undertakes first steps toward a ‘Philosophy of the Art of Science’ from a History of Science and Philosophy of Language perspective. Traditionally it is understood that Philosophy of Science assesses science as to the validity of its methods and to the question of how it is that we hold its claims to be true. However, the range of presuppositions here is considerable: Roughly, (...) it spans from Gottlob Frege's ‘The True’ (das Wahre) as the aim of scientific inquiry on the one end, to Paul Feyerabend's pluralistic understanding of science in a democratic society on the other. Despite this profound difference, however, we can nonetheless detect some similarity between them. Both hold science to be a normative endeavor: Frege thinks we ought to strive for true thoughts as somewhat independent ontological entities; Feyerabend thinks we ought to strive for a pragmatic humanism that takes the historicity of our knowledge into account. But while Frege ventured to show that natural language can benefit from insights drawn from the normative logic of formalized languages, Feyerabend discounted the idea of formalized language altogether, but with no less normative verve in regard to our scientific concept formation. Hence the combining question is whether scientific concept formation is indeed a rule‐governed behavior, or, put more generally, whether semantic content as such is normative. Guided by this question, the present paper draws a line from Frege through Russell, Wittgenstein, Carnap, and Quine, to those authors who follow or refute Saul Kripke's Wittgensteinian notion of semantic normativity in the most recent discussion of today. However, the paper does not proceed chronologically, but rather thematically along the major lines of argument. Hence after a brief survey of Feyerabend's philosophy of scientific concept formation (I), we explore Frege and his legacy on semantic normativity (II), and investigate the route that eventually led to present day semantic rule‐skepticism (III). We conclude with Carnap's ‘Principle of Tolerance’ combined with Feyerabend's notion of Science as an Art, parallels of which we can even find in Kant's third Critique (IV). (shrink)

We offer an interpretation of the words and works of Richard Dedekind and the David Hilbert of around 1900 on which they are held to entertain diverging views on the structure of a deductive science. Firstly, it is argued that Dedekind sees the beginnings of a science in concepts, whereas Hilbert sees such beginnings in axioms. Secondly, it is argued that for Dedekind, the primitive terms of a science are substantive terms whose sense is to be conveyed by elucidation, whereas (...) Hilbert dismisses elucidation and consequently treats the primitives as schematic. (shrink)

This essay discusses critically the ways in which different metaphors employed to illustrate the practices of knowledge production and knowledge acquisition as well as scientific and scholarly research shape our understanding of the academic form of life. The essay examines the metaphors of knowledge and their role in academia by means of philosophical analysis and a rhetorical analysis of language, thereby defending the core values of academic freedom. It focuses on two pairs of metaphors highly relevant to the tensions characteristic (...) of contemporary academic work: verticality and horizontality, on the one hand, and change and stability, on the other. The entanglement of perspectives from philosophy and historical rhetoric serves a metaphilosophical goal here: to show that our philosophical understanding of the nature of inquiry will be considerably enhanced if we seriously, and with both historical and literary sensibilities, study the metaphors we use in characterizing our epistemic and cognitive projects.

Hartry Field has argued that Alfred Tarski desired to reduce all semantic concepts to concepts acceptable to physicalism and that Tarski failed to do this. In the two succeeding decades, Field has been charged with being too lenient with Tarski; but it has been almost universally accepted that an objection at least as strong as Field's is telling against Tarski's theory. Close examination of the relevant literature, most of it printed in this journal in the 1930s, reveals that Field's conception (...) of physicalism is anachronistic. Tarski did succeed in furthering the sort of physicalist program he had in mind. (shrink)

Pierre Duhem's often unrecognized influence on twentieth-century philosophy of science is illustrated by an analysis of his significant if also largely unrecognized influence on Albert Einstein. Einstein's first acquaintance with Duhem's La Théorie physique, son objet et sa structure around 1909 is strongly suggested by his close personal and professional relationship with Duhem's German translator, Friedrich Adler. The central role of a Duhemian holistic, underdeterminationist variety of conventionalism in Einstein's thought is examined at length, with special emphasis on Einstein's deployment (...) of Duhemian arguments in his debates with neo-Kantian interpreters of relativity and in his critique of the empiricist doctrines of theory testing advanced by Schlick, Reichenbach, and Carnap. Most striking is Einstein's 1949 criticism of the verificationist conception of meaning from a holistic point of view, anticipating by two years the rather similar, but more famous criticism advanced independently by Quine in Two Dogmas of Empiricism.

An explicit philosophy and meta-philosophy of positivism, empiricism and popperianism is provided. Early popperianism is argued to be essentially a form of empiricism, the deviations from empiricism are traced. In contrast, the meta-philosophy and philosophy of an evolutionary naturalistic realism is developed and it is shown how the maximal conflict of this doctrine with all forms of empiricism at the meta-philosophical level both accounts for the form of its development at the philosophical level and its defense against attack from nonrealist (...) quarters. Following an earlier article on realism of similar theme (Synthese 26 (1974), 409) this paper then further explores the ramifications of a thoroughgoing realist position. (shrink)

The ArgumentDuring the nineteenth century, physicists and chemists, using different linguistic modes of expression, sought to describe the world for different purposes; thus, both disciplines gradually were nudged toward demarcation and self-image identification. In the course of doing so the rich complexity of the empire of chemistry was born. The essential challenge was closely connected with analysis, synthesis, and chemical process: learning the art ofwatchingsubstances change andmakingsubstances change. Pursued in theory-poor and phenomenology-rich contexts chemistry nevertheless made itself intellectually, professionally, societally, (...) and industrially creditable and attractive. The developing links between physics and chemistry are examined in this paper from the perspective of the discipline of chemistry more specifically than from the side of physics. Chemists came to believe that essentially physics was no more than mechanics. All else belonged to the domain of chemistry.Not before the last decades of the century were firm collaborative links and genuine reciprocity fostered between physics and chemistry, and then primarily on account of the common utility of scientific research tools. At a more fundamental level physics and chemistry, in contradistinction to all the other natural sciences, experienced partial overlap and convergence because of unique mutual reliance on the construction of systems each according to its own theoretical conceptions. Still amalgamation was unthinkable. Eventually physical chemistry was loosened from chemistry in the same way that, somewhat later, chemical physics was emancipated from physics. The intrinsic messiness of chemistry, one might suggest, tends more readily to foster Bohr's opinion that “there is no rock bottom to the study of nature,” rather than Einstein's view that “we can realistically, ultimately, put it all together.”.
