Albert Casullo (2000, 2003) and Shane Oakley (2011) argue that dilemma arguments against epistemic naturalism, such as those offered by Laurence BonJour (1998) and Harvey Siegel (1984), are such that, whatever strength they have against naturalism applies equally to moderate rationalist accounts of a priori justification. They conclude that dilemma arguments are, therefore, insufficient for establishing an advantage for moderate rationalism over naturalized epistemology. I argue that both Casullo's and Oakley's criticisms depend on an illicit assumption, namely, that dilemma arguments (...) presuppose a meta-justificatory demand that naturalists provide non-circular support for their basic sources of evidence. I argue that this assumption is not necessary for the force of dilemma arguments, and I construct a version that avoids this misreading. I conclude that, although there remain strategies for responding to dilemma arguments, they constitute a challenge naturalists must take seriously. (shrink)

Since at least the 1938 publication of Hans Reichenbach’s Experience and Predication , there has been widespread agreement that, when discussing the beliefs that people have, it is important to distinguish contexts of discovery and contexts of justification. Traditionally, when one conflates the two contexts, the result is a “genetic fallacy”. This paper examines genealogical critiques and addresses the question of whether such critiques are fallacious and, if so, whether this vitiates their usefulness. The paper concludes that while there may (...) be one or more senses in which genealogical critiques are fallacious, this does not vitiate their value. (shrink)

I examine the thesis that Otto Neurath anticipated the programme of naturalised epistemology already at the time of the Vienna Circle and consider the relation between Neurath's proposals and those of two contemporary theorists whose research programmes he would thus have broadly anticipated. The thesis is confirmed by reference to Neurath's own writings. The connection between Neurath's programme and the programmes of his two successors considered here, however, is found to be highly indirect in one case and nonexistent in the (...) other — despite their undeniable overlap.

Unlike more standard non-normative naturalizations of epistemology and philosophy of science, Larry Laudan's naturalized philosophy of science explicitly maintains a normative dimension. This paper critically assesses Laudan's normative naturalism. After summarizing Laudan's position, the paper examines (1) Laudan's construal of methodological rules as 'instrumentalities' connecting methodological means and cognitive ends; (2) Laudan's instrumental conception of scientific rationality; (3) Laudan's naturalistic account of the axiology of science; and (4) the extent to which a normative philosophy of science can be naturalized. It (...) is concluded that Laudan's normative naturalism is as problematic as its non-normative naturalist cousins. (shrink)

The traditional views of science as the possessor of a special method, and as the epitome or apex of rationality, have come under severe challenges for a variety of historical, psychological, sociological, political, and philosophical reasons. As a result, many philosophers are either denying science its claim to rationality, or else casting about for a new account of its rationality. In this paper a defense of the traditional view is offered. It is argued that contemporary philosophical discussion regarding the rationality (...) of science is plagued by a failure to distinguish among three different questions, all taken to be "the" question of the rationality of science. Once these questions are delineated, it becomes possible to answer one of them in such a way that the traditional link between science's rationality and its method is reestablished--although the scientific method is itself given a non-traditional rendering. In short, it is argued that there is a feature of science which is appropriately characterized as its method; that this method does in fact secure science's rationality; and that science is therefore correctly construed as preeminently rational. It is suggested in addition that the philosophy of science is itself best seen as a primarily epistemological activity, and consequently that a correction from the excessively historicist conception of recent philosophy of science is in order.

This paper considers two philosophical problems and their relation to science education. The first involves the rationality of science; it is argued here that the traditional view, according to which science is rational because of its adherence to (a non-standard conception of) scientific method, successfully answers one central question concerning science''s rationality. The second involves the aims of education; here it is argued that a fundamental educational aim is the fostering of rationality, or its educational cognate, critical thinking. The ramifications (...) of these two philosophical theses for science education are then considered, and a science education which takes reasons in science as its fundamental feature is sketched.

Connie Missimer (1990) challenges what she calls the Character View, according to which critical thinking involves both skill and character, and argues for a rival conception-the Skill View-according to which critical thinking is a matter of skill alone. In this paper I criticize the Skill View and defend the Character View from Missimer's critical arguments.

It is with some trepidation that I offer this critical review of Feyerabend's new book. I do not relish the prospect of getting involved in one of the nasty little fights Feyerabend picks with those who criticize his work. Nevertheless, Feyerabend's work cries out for critical attention. Of particular interest is the degree to which this new work deepens or enhances Feyerabend's earlier castigations of Reason. Fans of Feyerabend will be disappointed to learn that Feyerabend's philosophy is not deepened or (...) enhanced in any significant way, and that his responses to his critics are on the whole unconvincing.

In his 1983 article, Paul A. Roth defends the Quinean project of naturalized epistemology from the criticism presented in my 1980 article. In this note I would like to respond to Roth's effort. I will argue that, while helpful in advancing and clarifying the issues, Roth's defense of naturalized epistemology does not succeed. The primary topic to be clarified is Quine's "no first philosophy" doctrine; but I will address myself to other points as well.

With his distinction between the "context of discovery" and the "context of justification", Hans Reichenbach gave the traditional difference between genesis and validity a modern standard formulation. Reichenbach's distinction is one of the well-known ways in which the expression "context" is used in the theory of science. My argument is that Reichenbach's concept is unsuitable and leads to contradictions in the semantic fields of genesis and validity. I would like to demonstrate this by examining the different meanings of Reichenbach's context (...) distinction. My investigation also shows how the difference between genesis and validity precedes Reichenbach's context distinction and indicates approaches for meaningful applications of the concept of context to the phenomena designated by Reichenbach. I will begin by reconstructing the way in which Reichenbach introduces the distinction between discovery and justification as a difference of contexts (I). Drawing on the numerous meanings of the term "context", I will then emphasize some chief characteristics and review, through exemplification, the usage of this term. First of all, I turn to the context of discovery as the nonrational part of all scientific knowledge and show that this meaning cannot be defined consistently (la). For the context of justification, one can distinguish two main cases: the context of justification is either contrasted with the context of discovery, or it forms a unit there with. In the first case, the use of the context term becomes paradoxical, insofar as justification separated from scientific practice does not represent a field of reference which could be specifically contrasted with another field of reference (I b). In the second case, the unifying definitions contradict the contextual meaning of discovery and justification (1 c). In the last section, I point to a useful application of the concept of context which can be found in Reichenbach's argumentation and which refers to the practical conditions of justification(2).

What is the relation of epistemology, understood as the study of the evaluation of knowledge claims, and empirical psychology, understood as the study of the causal generation of a person's beliefs? Quine maintains that the relation is one of “mutual containment”.Epistemology in its new setting, conversely, is contained in natural science, as a chapter of psychology. … We are studying how the human subject of our study posits bodies and projects his physics from his data, and we appreciate that our (...) position in the world is just like his. Our very epistemological enterprise, therefore, and the psychology wherein it is a component chapter, and the whole of natural science wherein psychology is a component book—all this is our own construction or projection from stimulations like those we were meting out to our epistemological subject. There is thus reciprocal containment, though containment in different senses: epistemology in natural science and natural science in epistemology. (shrink)

In the production of knowledge about social life, two social contexts come together: the context of investigation, consisting of the social world of the investigator, and the context of explanation, consisting of the social world of the actors who are the subject of study. The nature of, and relationship between, these contexts is imagined in philosophy; managed, rewarded, and sanctioned in graduate seminars, journal reviews, and tenure cases; and practiced in research. Positivism proposed to produce objective knowledge by suppressing the (...) nonlogical and nonobservational aspects of the contexts. Attacks on positivism disputed the effectiveness and rationality of this strategy. Thus " postpositivism " can be understood as a series of attempts to reconstitute the relation between the contexts as the basis for accurate social knowledge. Two of the most important of these attempts—grounded theory and postmodern anthropology—are considered, and a synthesis, which draws from the insights of cultural sociology, is proposed. (shrink)

Although on opposite sides of the logic of discovery debate, Laudan and Simon share a thesis of divorce between discovery (invention) and justification (appraisal); but unlike some other authors, they do not base their respective versions of the divorce-thesis on the empirical/logical distinction. Laudan argues that, in contemporary science, invention is irrelevant to appraisal, and that this irrelevance renders epistemically pointless the inventionist program. Simon uses his divorce-thesis to defend his account of invention, which he claims to be non-inductive--so evading (...) the problem of induction. Underlying both authors' positions are inadequate conceptions of inductive inference. Laudan here ignores the role in contemporary science of plausibility arguments, which provide a crucial link between invention and appraisal, and thence an epistemic rationale for inventionism. Simon's account of invention does covertly call upon inductive principles from the context of appraisal, and this is what gives his program epistemic import; otherwise he would be vulnerable to Laudan's "no rationale" critique. The tensions in both authors reveal the falsity of the divorce-thesis, and the essential function of induction in both appraisal and invention of hypotheses. (shrink)

The main argument of this paper is that philosophical difficulties regarding scientific discovery arise mainly because philosophers base their arguments on a flawed picture of scientific research. Careful examination of N. R. Hanson's treatment of Kepler's discovery not only puts the rationality of this discovery beyond question, it also reveals what its rationality consists in. We can retrieve the point stressed by Hanson concerning the rational character of discoveries such as Kepler's even as we reject the type of "logical" analysis (...) he proposes. (shrink)

The point of the traditional distinction between the contexts of discovery and justification is to insist on the normative character of epistemology. The point is not to dismiss from epistemology merely the genesis of ideas; into the context of discovery go also descriptions of evaluative practices and decisions. However ideas are created, scrutinized, and judged, it is only the approbation to which they are entitled, accorded or not, that allegedly matters to epistemology. The criticism, familiar since N.R. Hanson's Patterns of (...) Discovery, that philosophy ought not to ignore the genesis of ideas is ironically conservative. If what is not normative epistemology is to be ignored, then the distinction would have us ignore even the reception and appraisal of scientific ideas. (shrink)

The paper investigates the implications of a nonaprioristic philosophy of science. It starts by developing a scheme of justification which draws its norms from the prevailing paradigm of rationality, which need not be universal or external. If the requirement for normativity is then abandoned we do not end up with a descriptive philosophy of science. The alternative to a prescriptive philosophy of science is a theoretical explanation of scientific decisions and acts. Explanation, rather than mere description, replaces justification; and the (...) paradigm of rationality becomes a scientific paradigm. The implications of these results for the discovery-justification distinction are investigated. An explanatory philosophy of science deals with the generation, as well as with the selection of scientific conjectures: both contexts have an epistemic dimension. * This paper was written under the auspices of the Wolfson Chair Extrordinary of Theoretical Physics, Tel Aviv University.

Evolutionary debunking arguments against religious beliefs move from the claim that religious beliefs are caused by off-track processes to the conclusion that said religious beliefs are unjustified and/or false. Prima facie, EDAs commit the genetic fallacy, unduly conflating the context of discovery and the context of justification. In this paper, we first consider whether EDAs necessarily commit the genetic fallacy, and if not, whether modified EDAs provide successful arguments against theism. Then, we critically evaluate more recent attempts to argue that (...) a more promiscuous evolutionary scepticism renders religious belief unjustified because, unlike commonsense and scientific beliefs, religious beliefs have no way out of such scepticism.

Quine's naturalized epistemology is ambivalent between a modest naturalism according to which epistemology is an a posteriori discipline, an integral part of the web of empirical belief, and a scientistic naturalism according to which epistemology is to be conducted wholly within the natural sciences. This ambivalence is encouraged by Quine's ambiguous use of science, to mean sometimes, broadly, our presumed empirical knowledge and sometimes, narrowly, the natural sciences. Quine's modest naturalism is reformist, tackling the traditional epistemological problems in a novel (...) way; his scientistic naturalism is revolutionary, requiring restriction and reconceptualization of epistemological problems. In particular, his scientistic naturalism trivializes the question of the epistemic standing of the natural sciences, whereas modest naturalism takes it seriously, and can offer a plausible answer.

In this paper, I try to articulate and clarify the role of the epistemic authority of experts in Kuhn’s explanation for the transition process between rival paradigms in the scientific revolutionary period. If science progresses, that process should contribute to the attainment of the cognitive aim of science, namely, the articulation of paradigms increasingly successful at the resolution of problems. It is hard to see that process as rational and as attaining the cognitive aim of science without the consideration of (...) epistemic authority.The mistake of Kuhn was to emphasize and clarify insufficiently the role of the epistemic authority of experts; his critics failed for ignoring it altogether.

A number of philosophers have argued that a naturalized epistemology cannot be normative, and thus that the norms that govern science cannot themselves be established empirically. Three arguments for this conclusion are here developed and then responded to on behalf of naturalized epistemology. The response is developed in three stages. First, if we view human knowers as part of the natural world, then the attempt to establish epistemic norms that are immune to scientific evaluation faces difficulties that are at least (...) as severe as the purported difficulties for naturalized epistemology. Second, some examples of the ways in which norms are proposed and evaluated in the course of scientific research are considered and it is concluded that science has no need for trans?scientific norms. Finally, the three arguments introduced at the outset have no force when they are viewed in the light of the preceding discussion. (shrink)

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)

Starting from the sixties of the past century theory change has become a main concern of philosophy of science. Two of the best known formal accounts of theory change are the post-Popperian theories of verisimilitude (PPV for short) and the AGM theory of belief change (AGM for short). In this paper, we will investigate the conceptual relations between PPV and AGM and, in particular, we will ask whether the AGM rules for theory change are effective means for approaching the truth, (...) i.e., for achieving the cognitive aim of science pointed out by PPV. First, the key ideas of PPV and AGM and their application to a particular kind of propositional theories - the so called "conjunctive propositions" - will be illustrated. Afterwards, we will prove that, as far as conjunctive propositions are concerned, AGM belief change is an effective tool for approaching the truth. (shrink)

We reflect on the nature, role and limits of non-empirical theory assessment in fundamental physics, focusing in particular on quantum gravity. We argue for the usefulness and, to some extent, necessity of non-empirical theory assessment, but also examine critically its dangers. We conclude that the principle of proliferation of theories is not only at the very root of theory assessment but all the more necessary when experimental tests are scarce, and also that, in the same situation, it represents the only (...) medicine against the degeneration of scientific research programmes.
