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.

Philip Kitcher rejects the global pessimists' view that the conclusions reached in inquiry are determined by the interests of some segment of the population, arguing that only some inquiries, for example, inquiries into race and gender, are adversely affected by interests. I argue that the biases Kitcher believes affect such inquiries are operative in all domains, but the prevalence of such biases does not support global pessimism. I argue further that in order to address the global pessimists' concerns, the scientific community needs criticism from people with diverse interests and background assumptions.

Devitt has developed an interesting defense of realism against the threats posed by the Pessimistic Induction and the Argument from Unconceived Alternatives. Devitt argues that the best explanation for the success of our current theories, and the fact that they are superior to the theories they replaced, is that they were developed and tested with the aid of better methods than the methods used to develop and test the many theories that were discarded earlier in the history of science. It is no surprise that theories developed earlier in the history of science needed to be replaced. But our current theories are different, having been developed and tested with the aid of these more recently developed superior methods. I critically analyze Devitt’s defense of realism. I argue that recent developments in methodology cannot support the claims Devitt makes. I present an argument I call the “Argument from Unconceived Methods.” Given the history of science, it seems likely that scientists will continue to develop new methods in the future. And some of these methods will enable scientists to generate data that cannot be reconciled with the currently accepted theories. Consequently, it seems that our current best theories are not immune from being replaced in the future by radically different theories.

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

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

David Oldroyd died in Sydney on 7 November 2014. Many readers of this journal would know of David’s impressive career as an historian of science and many would have also had the pleasure of knowing David personally. His academic career spanned across England, New Zealand and Australia, and his expertise in history of geology took him to several parts of the world for conferences and research, archival as well as geological, including Europe, China, Turkey, Russia and North America. His experiences and research led to numerous books, edited volumes, journal articles and book chapters.He was also a prolific book reviewer. As those associated with Metascience over the past 30 years would know, he made countless contributions to this journal, all of outstanding quality and showcasing his extensive expertise. Aside from his many reviews, David’s most outstanding published contributions to Metascience include his 1989 analysis of Paul Feyerabend’s critique of empiricism, “The Art-Science Ana..

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.

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

The pessimistic induction plays an important role in the contemporary realism/anti-realism debate in philosophy of science. But there is some disagreement about the structure and aim of the argument. And a number of scholars have noted that there is more than one type of PI in the philosophical literature. I review four different versions of the PI. I aim to show that PIs have been appealed to by philosophers of science for a variety of reasons. Even some realists have appealed to a PI. My goal is to advance our understanding of what the various PIs can teach us about science and the threat posed by PIs to scientific realism

This anthology focuses on three areas in the theory of knowledge: epistemic justification; analyses of knowledge and scepticism; and recent development in epistemology. Each of the three sections includes a brief introduction to the readings, a series of study questions, and a list of suggested readings. Section 1 deals with coherentism, foundationalism, reliabilism, and includes articles by Chisholm, BonJour, Audi, Goldman, and Fumerton. Section 2 deals with the analysis of knowledge and Gettier problems, and a variety of forms and responses to scepticism; it includes articles by Gettier, Conee, Feldman, Putnam, Nagel, and Stroud. Section 3 introduces the reader to recent developments in naturalized, feminist, and social epistemology, and includes articles by Quine, Almeder, Putnam, Anderson, Harding, Longino, Hardwig, Rorty, and Kitcher
