It has often been remarked that science is a young man's game. Thomas Kuhn, for example, claims that revolutionary changes in science are almost always initiated by either young scientists or those new to a field. I subject Kuhn's hypothesis to testing. I examine 24 revolutionary scientific figures mentioned in The Structure of Scientific Revolutions to determine if young scientists are more likely to make revolutionary discoveries than older scientists. My analysis suggests that middle-aged scientists are responsible for initiating more (...) scientific revolutions than young scientists, given the proportion of each group in the total population of scientists. I argue that the popular myth about the correlation between youth and scientific discovery fails to take into account the proportion of young scientists in the population of scientists. (shrink)

The anti-realist argument from underconsideration focuses on the fact that, when scientists evaluate theories, they only ever consider a subset of the theories that can account for the available data. As a result, when scientists judge one theory to be superior to competitor theories, they are not warranted in drawing the conclusion that the superior theory is likely true with respect to what it says about unobservable entities and processes. I defend the argument from underconsideration from the objections of Peter (...) Lipton. I argue that the inconsistency that Lipton claims to find in the argument vanishes once we understand what the anti-realist means when she claims that scientists are reliable. I also argue that collapsing the distinction between relative and absolute evaluations, as Lipton recommends, has its costs. Finally, I briefly examine Richard Boyd's influential defence of realism.

My aim in this paper is to re-examine specialization in science. I argue that we need to acknowledge the role that conceptual changes can play in the creation of new specialties. Whereas earlier sociological accounts focus on social and instrumental changes as the cause of the creation of new specialties, I argue that conceptual changes play an important role in the creation of some scientific specialties. Specifically, I argue that conceptual developments played an important role in the creation of both (...) endocrinology and virology. (shrink)

Rejectionists argue that collective belief ascriptions are best understood as instances of collective acceptance rather than belief. Margaret Gilbert objects to rejectionist accounts of collective belief statements. She argues that rejectionists rely on a questionable methodology when they inquire into the nature of collective belief ascriptions, and make an erroneous inference when they are led to believe that collectives do not really have beliefs. Consequently, Gilbert claims that collective belief statements are best understood as instances of belief. I critically examine (...) Gilbert’s criticisms of rejectionism. I argue that rejectionism is still a viable account of collective belief ascriptions. I also argue that Gilbert’s most powerful criticism provides important insight into what really stands between her and the rejectionists. Gilbert and the rejectionists do not yet agree about what background assumptions can be made in developing an account of collective belief ascriptions. (shrink)

I examine two challenges that collaborative research raises for science. First, collaborative research threatens the motivation of scientists. As a result, I argue, collaborative research may have adverse effects on what sorts of things scientists can effectively investigate. Second, collaborative research makes it more difficult to hold scientists accountable. I argue that the authors of multi-authored articles are aptly described as plural subjects, corporate bodies that are more than the sum of the individuals involved. Though journal editors do not currently (...) conceive of the authors of multi-authored articles this way, this conception provides us with the conceptual resources to make sense of how collaborating scientists behave.Keywords: Collaborative research; Authorship; Multi-authored articles; Responsibility; Reward system; Plural subject.

This chapter discusses Kuhn’s conception of the history of science by focussing on two respects in which Kuhn is an historicist historian and philosopher of science. I identify two distinct, but related, aspects of historicism in the work of Hegel and show how these are also found in Kuhn’s work. First, Kuhn held tradition to be important for understanding scientific change and that the tradition from which a scientific idea originates must be understood in evaluating that idea. This makes Kuhn (...) a historicist in a sense we may call conservative. Secondly, Kuhn held that there is a pattern to the development of science. In the light of the fact that he held scientific change to be law-like, we can call this second aspect of Kuhn’s historicism determinist. I discuss the relationship of Kuhn’s historicist historiography to the philosophical purposes he had for his history of science, namely to refute a conception of scientific progress as driven towards increasing truth by something like ‘the scientific method’. I argue that while this determinism refutes certain positivist conceptions of scientific change, it also requires internalism—the view that the causes of scientific change come from within science, not from outside. Consequently, Kuhn’s historiography of science contrasts with that implicit in much of post-Kuhnian science studies. (shrink)

This paper examines love as a concept for advancing our understanding of the ethics of leadership. We draw upon writings that consider love to be at the heart of modern subjects’ search for meaning and affective attachment to organisation – necessitating, we argue, an exploration of leadership too in these terms. Existing works on leaders’ supposed love for those they lead are considered. These serve as a springboard from which to undertake a philosophical examination of two dominant formulations of an (...) ethics of love in Western culture: neighbour and agapeic love. Neither of these conceptualisations, we argue, suffice as an understanding of leadership. We draw upon Kierkegaard to highlight the category error of conceptualising leadership in terms of neighbour love, and feminist writings to highlight the deeply problematic sacrificial demand at the heart of agapeic love. Drawing attention to the plenitude of other loves yet to be explored by business ethics scholarship, we propose two organising foci for advancing our understandings: a focus on humanising love by leaders, and a focus on problematising love of leaders.

I examine the epistemic import of collaborative research in science. I develop and defend a functional explanation for its growing importance. Collaborative research is becoming more popular in the natural sciences, and to a lesser degree in the social sciences, because contemporary research in these fields frequently requires access to abundant resources, for which there is great competition. Scientists involved in collaborative research have been very successful in accessing these resources, which has in turn enabled them to realize the epistemic (...) goals of science more effectively than other scientists, thus creating a research environment in which collaboration is now the norm.

I present a history of Kuhn’s discovery of paradigms, one that takes account of the complexity of the discovery process. Rather than emerging fully formed in Structure , the concept paradigm emerged through a series of phases. Early criticism of Structure revealed that the role of paradigms was unclear. It was only as Kuhn responded to criticism that he finally articulated a precise understanding of the concept paradigm. In a series of publications in the 1970s, he settled on a conception (...) of a paradigm as a concrete exemplar that functions as a guide to future research. (shrink)

This paper provides an analysis of the Preface and Chapter 1 of Thomas Kuhn's The Structure of Scientific Revolutions. It will be translated into German, and published in a volume edited by Markus Seidel.

Many have criticized the peer-review system employed in scientific publication because of the apparent lack of inter-referee reliability. It is often remarked that if referees cannot agree about the quality of a scientific manuscript, then the selection of manuscripts for publication is arbitrary. Some critics have even called for abolishing pre-publication peer-review. I argue that too much emphasis has been put on inter-referee reliability. As such, a lack of inter-referee reliability in the current peer-review system is not damning for the (...) system. I argue that peer review is effective at finding mistakes. (shrink)

Kuhn argues that science does not aim at the truth. Alexander Bird raises concerns form Kuhn's view. I defend Kuhn's claim and argue that insofar as science has a goal it is a moving target.

Kuhn’s Structure of Scientific Revolutions has been attacked for many reasons. Key analytic terms, most importantly “paradigm,” were widely regarded as poorly defined. To many readers Structure seemed to suggest that the process of theory change is irrational, or at least non-rational. And even his characterization of normal science seemed to some readers to paint a very unflattering picture of scientists as excessively dogmatic and uncritical. More recently, Lorraine Daston has argued that the notion of “structure” that figures in the (...) title of the book, as well as in the analysis of the history of science discussed throughout the book, is “dusty and dated”. Historians of science tend to focus on the particular, in recognition that the sorts of events they study are unique. My aim in this paper is to defend Kuhn’s appeal to the notion of structure. First, I argue that Structure of Scientific Revolutions is not primarily a contribution to the history of science, despite the fact that it cites many historical sources and articles in the history of science. Consequently, it is a mistake to regard Kuhn’s appeal to the notion of structure as a case of badly written history of science. Second, I argue that insofar as the book is a contribution to philosophy, the sort of thing Kuhn means by “structure” is perfectly respectable, and is often presupposed in many philosophical studies, especially in general philosophy of science. Third, I defend Kuhn’s analysis of science, especially the enterprise of identifying the structure of scientific revolutions. (shrink)

Van Fraassen believes our current best theories enable us to make accurate predictions because they have been subjected to a selection process similar to natural selection. His explanation for the predictive success of our best theories has been subjected to extensive criticism from realists. I aim to clarify the nature of van Fraassen’s selectionist explanation for the success of science. Contrary to what the critics claim, the selectionist can explain why it is that we have successful theories, as well as (...) why it is reasonable to expect past successful theories to be successful in the future. I also argue that the plausibility of the realists’ explanation rests on an inaccurate understanding of the nature of predictive success . The predictive success of our best theories is a relative success. (shrink)

I examine a number of recent challenges to traditional individualist epistemologies. In chapter I, I examine Margaret Gilbert's claim that certain types of communities, "plural subjects," are capable of having what she calls "collective beliefs." In chapter II, I examine Lynn Hankinson Nelson's claim that communities, and not individuals, are the primary epistemological agents. In chapter III, I examine Miriam Solomon's claim that scientific rationality is a property of communities, not individuals. In chapter IV, I examine Richard Rorty's claim that (...) solidarity is the end of inquiry. Finally, in chapter V, I examine Helen Longino's claim that scientific knowledge and inquiry are mediated by processes that are irreducibly social. ;I argue that many philosophers who argue for a more social epistemology are mistaken about what role the community plays in inquiry, and that only individuals are epistemic agents--only they believe, know, and act rationally. In this respect, traditional individualist epistemologies are correct. I also argue that what is distinctively and irreducibly social about inquiry are the norms and processes that mediate our interaction with each other. These norms and processes require numerous individuals to sustain them. Further, I argue that given this understanding of the role of the community in inquiry we are required to change our understanding of both the nature and role of the individual knower, and the project of epistemology. Individual knowers are dynamic, changing their conception of themselves as they interact in the world with others. An integral but hitherto neglected part of epistemology is the evaluation of the social processes that mediate our interaction with others. (shrink)

I examine the degree of specialization in various sub-fields of philosophy, drawing on data from the PhilPapers Survey. The following three sub-fields are highly specialized: Ancient philosophy, seventeenth/eighteenth century philosophy, and philosophy of physics. The following sub-fields have a low level of specialization: metaphilosophy, philosophy of religion, philosophy of probability, philosophy of the social sciences, decision theory, and philosophy of race and gender. Highly specialized sub-fields tend to require extensive knowledge in some area beyond the typical training of a philosopher, (...) and outside of philosophy proper. In addition, there is a correlation between sub-field size and degree of specialization. Larger sub-fields tend to be more specialized. (shrink)

A common reaction to crises experienced within or brought about by business is to identify a corollary ‘crisis of leadership’ and to call for better (stronger, more thoughtful or, indeed, more ethical and responsible) leaders. This paper supports the idea that there is a crisis of leadership – but interprets it quite differently. Specifically, I argue that the most ethically debilitating crisis is the fact that we look to leadership to solve organisational ethical ills. There is, I argue, a pressing (...) need to conceptualise a business ethics that is not constrained by the straitjacket of official hierarchy – a need to denaturalise ‘leadership’ as the normal or rightful locus of ethical regulation and renewal in business organisation. To this end, I explore a Levinasian ethico-politics of responsibility and proximity as the basis of an alternative, anti-sovereign, ethics of organisation. (shrink)

The literature on collective belief and collective intentionality has grown rapidly and is now quite extensive. Philosophers have applied the concepts of “collective belief” and “collective intentionality” in a variety of contexts, including political and legal contexts as well as scientific contexts, specifically to model the behavior of research teams and scientific specialties.

I challenge Gareth Eaton’s recent claim that Theodore Richards should be counted among the discoverers of isotopes. In evaluating Eaton’s claim, I draw on two influential theories of scientific discovery, one developed by Thomas Kuhn, and one developed by Augustine Brannigan. I argue that though Richards’ experimental work contributed to the discovery, his work does not warrant attributing the discovery to him. Richards’ reluctance to acknowledge isotopes is well documented. Further, the fact that he made no claim to having made (...) the discovery also undermines Eaton’s argument. (shrink)

I argue that van Fraassen’s selectionist explanation for the success of science is superior to the realists’ explanation. Whereas realists argue that our current theories are successful because they accurately reflect the structure of the world, the selectionist claims that our current theories are successful because unsuccessful theories have been eliminated. I argue that, unlike the explanation proposed by the realist, the selectionist explanation can also account for the failures of once successful theories and the fact that sometimes two competing (...) theories are both equally successful. (shrink)

David Hull accounts for the success of science in terms of an invisible hand mechanism, arguing that it is difficult to reconcile scientists' self-interestedness or their desire for recognition with traditional philosophical explanations for the success of science. I argue that we have less reason to invoke an invisible hand mechanism to explain the success of science than Hull implies, and that many of the practices and institutions constitutive of science are intentionally designed by scientists with an eye to realizing (...) the very goals that Hull believes need to be explained by reference to an invisible hand mechanism. Thus, I reduce the scope of Hull's invisible hand explanation and supplement it by appealing to a hidden hand explanation. (shrink)

In this book K. Brad Wray provides a comprehensive survey of the arguments against scientific realism. In addition to presenting logical considerations that undermine the realists' inferences to the likely truth or approximate truth of our theories, he provides a thorough assessment of the evidence from the history of science. He also examines grounds for a defence of anti-realism, including an anti-realist explanation for the success of our current theories, an account of why false theories can be empirically successful, (...) and an explanation for why we should expect radical changes of theory in the future. His arguments are supported and illustrated by cases from the history of science, including a sustained study of the Copernican Revolution, and a study of the revolution in early twentieth century chemistry, when chemists came to classify elements by their atomic number rather than by their atomic weight.

Petrovich provides an insightful study on analytic philosophy (AP) with the intention of determining whether this sub-field of philosophy has been operating within what Kuhn calls a normal science framework. Through a citation analysis, Petrovich concludes that AP does not exhibit the sort of pattern that we would expect of a field operating in a normal science phase. I take issue with Petrovich’s way of measuring normal science. I provide some insight into how we might better measure normal science in (...) future studies. (shrink)

Though many agree that we need to account for the role that social factors play in inquiry, developing a viable social epistemology has proved to be a difficult task. According to Longino, it is the processes that make inquiry possible that are aptly described as social, for they require a number of people to sustain them. These processes not only facilitate inquiry, but also ensure that the results of inquiry are more than mere subjective opinions, and thus deserve to be (...) called knowledge. In this paper, I explain Longino’s epistemology and defend it against criticisms recently raised by Kitcher, Schmitt and Solomon. Longino rightly recognizes that not all social factors have the same affect on inquiry. She also recommends that we reconceptualize ‘knowledge,’ distinguishing knowledge from opinion by reference to a social standard. (shrink)

It is widely assumed that it is the anti-realist who stakes his case on evidence from the history of science. I argue that realists have failed to recognize the need to collect evidence from the history of science to support their methodological claims, and anti-realists do not rely on evidence from the history of science to the extent that many suggest.

I defend an alternative reading of §56 of Frege's Grundlagen, one that rescues Frege from Dummett's charge that this section is the weakest in the whole book. On my reading, Frege is not presenting arguments against the adjectival strategy. Rather, Frege presents the definitions in §55 in order to convince his reader that numbers must be objects. In §56 Frege suggests that these definitions contain two shortcomings that adequate definitions of numbers must overcome. And these short-comings, he argues, can only (...) be avoided if numbers are objects. Further, I have argued that my alternative reading defuses three of Dummett's four criticisms of §56, consequently challenging Dummett's claim that this section should be stigmatized as the weakest in the whole book. Nevertheless, I am inclined to agree with Dummett that the adjectival strategy is more robust than Frege suggests. Frege's arguments seem far from conclusive. Thus, it may be that the adjectival strategy can provide us with definitions that can do everything we can expect from adequate definitions of numbers. (shrink)

In this dissertation, we construct a consistent, complete quotational logic G$\sb1$. We first develop a semantics, and then show the undecidability of circular quotation and anaphorism . Next, a complete axiom system is presented, and completeness theorems are shown for G$\sb1$. We show that definable truth exists in G$\sb1$. ;Later, we replace equality in G$\sb1$ with an equivalence relation. An axiom system and completeness theorems are provided for this equality-free version of G$\sb1$, which is useful in program verification. ;Interpolation and (...) definability are discussed in intensional and extensional contexts. We show that G$\sb1$ contains the complete first order theory of arithmetic by implicit definitional extension. ;The last chapter deals with representability and fixed points. Derived induction schemata are produced, and G$\sb1$ is shown to be a recursion theory. We give an example of how G$\sb1$ may be used to solve domain equations of Scott. (shrink)

Our tolerance for, and promotion of, linguistic irregularity is a key arbitrator between Arbib's proposal that holistic protolanguage preceded culturally imposed compositionality, and the standard view that discrete units with word-like properties came first. The former, coupled with needs-only analysis, neatly accounts for the second-order linguistic complexity that is rationalised as fuzzy grammaticality, subclass exception, and full irregularity.

Though many agree that we need to account for the role that social factors play in inquiry, developing a viable social epistemology has proved to be difficult. According to Longino, it is the processes that make inquiry possible that are aptly described as "social," for they require a number of people to sustain them. These processes, she claims, not only facilitate inquiry, but also ensure that the results of inquiry are more than mere subjective opinions, and thus deserve to be (...) called "knowledge." In this paper, I (a) explain Longino's epistemology, and (b) defend it against charges that have recently been raised by Kitcher, Schmitt, and Solomon. Longino rightly recognizes that not all social factors have the same (adverse) affect on inquiry. She also recommends that we distinguish knowledge from mere opinion by reference to a social standard. (shrink)

Thomas Kuhn was never a player in the contemporary realism/anti-realism debates, the debate that gained momentum around 1980 or so, with the publication of Bas van Fraassen’s Scientific Image and Larry Laudan’s “Confutation of Convergent Realism”. But I argue that Kuhn had a significant influence on these debates. Kuhn played a significant role in focusing philosophers’ attention on a different issue than the focus of the realism/anti-realism debate of the 1950s and 1960s. Instead of focusing on the meaning of theoretical (...) terms, philosophers of science turned their attention to the problems raised by changes of theory. The particular shape of the contemporary debate thus owes something to the publication of Structure of Scientific Revolutions. (shrink)

Many approaches to dignity endorse the Human Scope Thesis (HST), according to which almost all humans and almost only humans have dignity. I argue that justifications for this thesis are doomed to fail. Proponents of the HST can be broadly divided into two camps, according to how they defend this thesis against the Scope Challenge. This challenge states that there is no non-arbitrary way of restricting the scope of dignity that includes almost all and almost only humans. Naturalistic Accounts attempt (...) to find a property which roughly matches the HST, while Conventionalist Accounts attempt to explain why endorsing the HST is necessary to achieve coherence with the human rights project. I argue that neither strategy overcomes the Scope Challenge. I then draw out the important implications of this. Even as dignity retains relevance to all humans, it must move beyond the mere human, so as to include nonhuman animals. (shrink)

This is a book review of John Heilbron's book _Niels Bohr: a very short introduction_.

This Introduction provides a rationale for a collection of new paper on Thomas Kuhn. Scholarship on Kuhn has changed dramatically in the last 20 years for numerous reasons. First, scholars studying Kuhn no longer focus narrowly on Structure of Scientific Revolutions. Scholars have been giving careful consideration to Kuhn’s later work. Second, many scholars have been drawing on the vast unpublished resources at the Thomas S. Kuhn Archive at MIT. Third, with the 50th anniversary of the publication of Structure in (...) 2012, there were quite a number of conferences held which led to the publication of a number of volumes reflecting on Kuhn’s impact in philosophy and history of science. These three developments have contributed significantly to our collective understanding of Kuhn and his theories of scientific change and scientific knowledge. Though Kuhn’s position in the philosophy of science can be difficult to gauge, by objective measures Kuhn’s impact is undeniable. Kuhn’s influence outside philosophy of science is also astounding, especially in the social sciences. So it is beyond dispute that Kuhn has had a profound and wide-ranging impact on scholarship.

I critically examine Rorty's social epistemology, specifically his claim that the end of inquiry is solidarity.

Studies of epistemic communities and collaborative research in the social sciences have deepened the understanding of how science works, and more specifically how the social dimensions of scientific practice both enable and impede social scientists in realizing their epistemic goals. Two types of studies of epistemic communities are distinguished: general theories of epistemic communities aim to construct accounts of theoretical change applicable to all social scientific specialties, whereas historical studies emphasize the contingencies that affect specific social scientific disciplines, subfields, or (...) institutions. Although collaborative research plays a less pronounced role in the social sciences than in the natural sciences, collaboration has enabled social scientists to investigate topics that would otherwise be difficult to investigate.

It is widely recognized that conceptual and theoretical innovations and the employment of new instruments and experimental techniques are important factors in explaining the growth of scientific knowledge in chemistry. This study examines another dimension of research in chemistry, collaboration and co-authorship. I focus specifically on Theodore Richards’ career and publications. During the period in which Richards worked, co-authorship was beginning to become more common than it had been previously. Richards was the first American chemist to be awarded a Nobel (...) Prize and he was at the forefront in this new trend in chemistry. He collaborated more than was typical for his time, with many scientists, in different sized groups, and he often had persistent collaborative relationships, extending over a number of years. Further, it appears that these collaborations benefited Richards, his collaborators, and the field of chemistry as a whole. (shrink)

Kuhn's Structure of Scientific Revolutions has been enduringly influential in philosophy of science, challenging many common presuppositions about the nature of science and the growth of scientific knowledge. However, philosophers have misunderstood Kuhn's view, treating him as a relativist or social constructionist. In this book, Brad Wray argues that Kuhn provides a useful framework for developing an epistemology of science that takes account of the constructive role that social factors play in scientific inquiry. He examines the core concepts of (...) Structure and explains the main characteristics of both Kuhn's evolutionary epistemology and his social epistemology, relating Structure to Kuhn's developed view presented in his later writings. The discussion includes analyses of the Copernican revolution in astronomy and the plate tectonics revolution in geology. The book will be useful for scholars working in science studies, sociologists and historians of science as well as philosophers of science. (shrink)
