Karl Popper’s description of the open society in terms of respect, rather than mere tolerance, appears to be highly relevant today. Although he never explicitly addressed the issues of multiculturalism and valuepluralism in contemporary societies, Popper’s idea of respect provides an effective way to approach them. For, on the one hand, it may help to reframe current debates about multiculturalism in clearer terms. On the other, it provides a critical assessment of the widespread relativism that presents itself as a sort (...) of panacea of all theoretical and practical problems posed by the cohabitation of groups sharing different values and worldviews. On closer scrutiny, political relativism – just as its epistemological counterpart – is not only entirely inadequate but also dangerous for the very existence of the open society. A serious look at the present situation suggests, rather, the adoption of a principle of reciprocity that is consistent with Popper’s critical pluralism and might prove to be effective in addressing the problems faced by a multicultural society.

Popper’s theory of learning is sometimes met with incredulity because Popper claims that there is no transference of knowledge or knowledge elements from outside the individual, neither from the physical environment nor from others. Instead, he claims that we can improve our present theories by discovering their inadequacies.The intent of this article is not to persuade educators to adopt Popper’s approach uncritically to build their professional knowledge. Rather, it presents a discussion on the need for teachers to adopt a critical (...) approach in eliminating what is inadequate and preserve what is adequate by modifying or abandoning whatever traditions or practices that are inadequate to improve their teaching practice. Popper claims that knowledge advances by searching for and eliminating error contained in our theory. In other words, we can improve our present theories by finding out their inadequacies. (shrink)

In his biography of Karl Popper, Malachi Hacohen brilliantly reconstructs the development of Popper's ideas through 1946, correcting many errors regarding the sequence of their emergence. In addition he recreates Popper's Vienna and provides insights into Popper's complex personality. A larger goal of Hacohen's narrative is to show the relevance of Popper's philosophical and political thought for the left. Unfortunately this leads him to neglect and distort certain aspects of the story he tells, particularly when it comes to the relationship (...) between Popper and F.A. Hayek. (shrink)

Among the various institutional structures of an economy like the firm and the marketplace is one that is like no other. Science is unique. This uniqueness raises an important question: why does science exist? From an economic perspective, there are two potentially meaningful approaches to the existence of science. They both encompass institutional pluralism. A substitutes theory of comparative institutions presupposes the primacy of the commercial marketplace over firms—that firms substitute for the market when markets fail. This theory has not (...) been used to explain the existence of science. A complements theory postulates that many simultaneous institutional responses, including science, are necessary for creating an efficient and equitable economy. The economic function of science is to produce fundamental theoretical abstractions about our world. Scientific theories are public goods that would not likely be produced within the governance structures of commercial markets and firms. The aim is to complement but not supplant traditional philosophical answers that science exists to discover truth and knowledge. (shrink)

Despite his well‐known deductivism, in his early (unpublished) writings, Popper held an inductivist position. Up to 1929 epistemology entered Popper's reflections only as far as the problem was that of the justification of the scientific character of these fields of research. However, in that year, while surveying the history of non‐Euclidean geometries, Popper explicitly discussed the cognitive status of geometry without referring to psycho‐pedagogical aspects, thus turning from cognitive psychology to the logic and methodology of science. As a consequence of (...) his reflections on the problematic relationship between geometrical‐mathematical constructions and physical reality Popper was able to get over a too direct notion of such a relationship, cast doubts on inductive inference and started conceiving in a new (strictly non‐inductivist) manner the relationship between theoretical and observational propositions.

The goal of this dissertation is to reconstruct, critically evaluate, and apply the pluralism of Paul Feyerabend. I conclude by suggesting future points of contact between Feyerabend’s pluralism and topics of interest in contemporary philosophy of science. I begin, in Chapter 1, by reconstructing Feyerabend’s critical philosophy. I show how his published works from 1948 until 1970 show a remarkably consistent argumentative strategy which becomes more refined and general as Feyerabend’s thought matures. Specifically, I argue that Feyerabend develops a persuasive (...) case against rationalism, or the thesis that there exist normative and exclusive rules of scientific rationality. In Chapter 2, I reconstruct Feyerabend’s pluralism and detail its relationship to his humanitarianism and epistemological anarchism. I understand Feyerabend’s pluralism as the combination of the principles of proliferation and tenacity. I show the evolution and justification of these principles from Feyerabend’s early papers until the late 1970s. In Chapter 3, I defend Feyerabend’s pluralism from its most prominent criticisms. I then clarify that Feyerabend’s pluralism amounts to a conception of the logic of theory pursuit and modify his view using insights from C.S. Peirce, Pierre Duhem, and Michael Polanyi. From Peirce, I show how economic, sociological, and value-laden features of theory pursuit may be used to constrain proliferation and tenacity. From Duhem and Polanyi, I try to show the proper role of tacit knowledge within a Feyerabendian framework. Finally, I show what implications Feyerabend’s pluralism has for models of distributing funds within scientific communities. I contend that it provides a more promising model that the ‘well-ordered science’ proposal advanced by numerous philosophers and social scientists. Specifically, I aim to understand what taking Feyerabend’s pluralism seriously entails for principles of balancing funding allocation decisions and the role of peer-review in evaluating the potential success of research proposals. I conclude by suggesting future lines of research for further analyzing and applying Feyerabend’s pluralism. (shrink)

University of North Carolina at Greensboro Most approaches to the philosophy of the natural and social sciences are basedon completed scientific investigations. However, there are many importantcases in science in which testing is incomplete. These cases are termed suspendedtrials and are particularly significant in biomedical and allied health fields. Initially,the authors' interest in suspended trials was piqued by a controversialmethod for assisting autistic children known as facilitated communication. Thisarticle examines facilitated communication and other examples of suspendedtrials from the perspective of (...) an economics of science and game theory. Themodel is consistent with recent evolutionary approaches to the philosophy ofthe natural and social sciences and with recent contributions to an economicunderstanding of science. Key Words: clinical trials • innovative therapies • economics of science • suspended trials • facilitated communication • economics of clinical research. (shrink)

Increasing the “truth per dollar” of money spent on science is one legitimate long-run goal of the economics of science. But before this goal can be achieved, we need to increase our knowledge of the successes and failures of past and current reward structures of science. This essay reviews what economists have learned about the behavior of scientists and the reward structure of science. One important use of such knowledge will be to help policy-makers create a reward structure that is (...) more efficient in the future. (shrink)

Bartley’s pancritical rationalism is seen by some as being a refinement of Popper’s critical rationalism. I contest this view and argue that pancritical rationalism is obtained from critical rationalism by removing some of its most important and useful features. The remainder consists of a restatement of some of Popper’s key ideas and an interpretation of others that I attempt to show is not entirely faithful to what Popper says.

Expanding on recent philosophical contributions to the conceptual and normative framework of scientific imperialism, I examine whether the economics approach to social epistemology can be considered a case of economics imperialism and determine whether economics’ explanatory expansionism appropriately contributes to this philosophical subfield or not. I argue first that the economics approach to social epistemology counts as a case of economics imperialism under a broad conception of the term, and second that we have good reasons to doubt the appropriateness of (...) the incursion of economics into social epistemology, insofar as economics’ attempt at explanatory unification fails to express significant human interests.

Currently, testimony is studied extensively in Anglo-American philosophy. However, most of this work is done from a justificationist perspective in which philosophers try to justify our reliance on testimony in some way. I agree with Popper that justificationism is radically mistaken. Thus, I construct an account of how we respond to testimony that in no way attempts to justify our reliance on it. This account is not a straightforward exegesis of Popper, as he never tackled testimony systematically. It makes use, (...) however, of several of Popper's key insights and incorporates them into a viable theory of testimony. Key Words: testimony • anti-justificationism • social epistemology • situational analysis • defeasibility. (shrink)

Popper claims that error indicates what to avoid and there is no recipe for how to proceed. Most rationalist philosophers ignore his arguments and still try to justify their views instead of trying to improve upon them by criticizing them and conjecturing alternatives. In public discourse barren forms of justification are widespread. More and better critical institutions are required, and these require political compromise on shared aims.
