Timur Kuran's Private Truths, Public Lies makes a compelling case that people often misrepresent their private preferences in response to real or imagined social pressures, that the relative power of competing interest groups to punish opinion deviance and reward conformity determines the patterns and pervasiveness of preference falsification, and that preference falsifi‐cation helps explain such diverse outcomes as the persistence and sudden collapse of communism and the precarious persistence of racial preferences in the United States and of (...) the caste system in India. Although preference falsification is important and raises questions about the legitimacy of the opinions expressed in opinion polls and elections, it does not seem widespread enough to warrant the conclusion that ordinary people lack the courage necessary to make democracy work.

(1) What may be gained by applying concepts generalised from economics to methodological problems? The perspective of cost-benefit analysis ('CBA' for short) may help the researcher to see what sorts of questions he should take into account when dealing with particular methodological problems. This claim is supported by applying generalised CBA-thinking to two standard problems of methodology. (2) In the practice of research the handling of basic statements does not normally constitute any problem, and no conscious decision is involved. In (...) the methodological reconstruction the key questions are: 'How can a particular basic statement be criticised?' and 'What are the costs of defending a statement that is "problematic"?' The problem of the empirical 'base' is an investment problem: whether or not to invest time and effort into processing a particular basic statement into a falsifying hypothesis for the theory we wish to test. The valuation of the costs of rejecting or, as the case may be, of defending a basic statement, are objective. (3) With respect to theories, in basic science, the issue is not one of acceptance or rejection of a single theory, but rather of theory preference. Both the rational response to a falsification and rational theory preference are governed by CBA-considerations. The option for one of two competing theories is based upon a CBA where the valuation of benefits and costs is objective. Theory change is an objective process, at least in those fields, where theorising is closely controlled by empirical testing: the better theory drives out the less good theory. The costs of defending a theory that is less good than its competitor are mainly epistemic resources forgone. The use of CBA in methodology not only is compatible with Popper's position, but it may pay to view Popper's methodology as an application of CBA to epistemic situations. (shrink)

Karl Popper defines an ad hoc hypothesis as one that is introduced to immunize a theory from some (or all) refutation but which cannot be tested independently. He has also attempted to explicate ad hocness in terms of certain other allegedly undesirable properties of hypotheses or of the explanations they would provide, but his account is confused and mistaken. The first such property is circularity, which is undesirable; the second such property is reduction in empirical content, which need not be. (...) In the former case, I argue that non-circularity is in any event preferable to non-ad hocness as a necessary condition for a satisfactory explanation or an explanans, as the case may be, and I try to sort out various persistent errors surrounding this comparison. In the latter case, I suggest that Popper is barking up the wrong tree, that important scientific progress sometimes does consist in just such reductions in empirical content as he proscribes. This provides a further reason for not taking ad hoc hypotheses as Popper conceives them to pose the danger for science he believes they do. (shrink)

This article seeks to show that E.A. Milne’s philosophy of science has its roots in the philosophy of Aristotle and it could be an inspiration for Popper’s philosophy. The similarities with Aristotle’s concept are as follows: 1) the aim of science is to explain phenomena by discovering general principles; 2) the mind is responsible for discovering them, although experience guides the search; 3) deducing detailed statements from general assumptions is the most important element of research. On the other hand, Milne’s (...) proposal is consistent with Popper’s main ideas: 1) criticism of the principle of induction; 2) preference for the hypothetical-deductive method ; 3) appreciation of falsification and confidence in the effectiveness of deductive logic.

This volume, and in general this moment in the history of science, is calling for us linguists, and especially those of us who have worked in Minimalism, to characterize what it is that our approach has discovered, that we want to embrace and move forward with, and what it is that we need to discard. There is plenty in both categories, and it is precisely the considerations of biology (e.g. language evolution) that can help us weed out the burdensome, damaging (...) aspects of this approach. Too often we linguists look down upon the study of language evolution as some kind of marginal topic that need not concern “true” linguists, and we prefer to just wait until geneticists, biologists, and neuroscientists figure it all out. And yet, it is only linguists who can put forward specific, linguistically informed hypotheses that can be subjected to interdisciplinary testing. The emphasis here is on specific, falsifiable hypotheses, rather than some vague assertions that cannot be subjected to falsification. It is true that many such specific hypotheses will be proven wrong, but after all, the nature of the scientific process is simply to narrow down the range of possibilities. My focus here is on a few influential assumptions/postulates in Minimalism that are particularly harmful in establishing meaningful links between language and biology, and which, both on this ground, and based on more careful linguistic considerations, should be abandoned. I will also point to certain postulates... (shrink)

While evidence-based medicine (EBM) is often accused on relying on a paradigm of 'absolute truth', it is in fact highly consistent with Karl Popper's criterion of demarcation through falsification. Even more relevant, the first three steps of the EBM process are closely patterned on Popper's evolutionary approach of objective knowledge: (1) recognition of a problem; (2) generation of solutions; and (3) selection of the best solution. This places the step 1 of the EBM process (building an answerable question) in (...) a pivotal position for the understanding of the whole process, and underscores a few aspects which are often overlooked in EBM courses. First in this step internal evidence (including personal expertise) must be appraised and integrated in the problem. Second, issues of applicability of the possible solution should be anticipated. Third, and possibly more important, the goal of the intervention should be set at this stage (typically by choosing the outcome in a PICO question). Depending whether or not goals depend on the goals of others, and whether they concern others' voluntary behaviour, goals may be classified as self-serving, moral, altruistic or moralistic. Thus, delicate ethical questions must be addressed at this stage, which means that patient preferences and values must be carefully sought, so that empathy, counselling and narrative medicine must be mastered to be able to formulate correctly an answerable question. The need to modify the current description of the EBM process to increase the recognition of implicit assumptions and increase the consistency of this model is discussed. (shrink)

Relational theories of art—paradigmatically, the ‘Institutional’ theory—arose from dissatisfaction with the Wittgenstein-inspired ‘family resemblance’ account of art, and were taken not merely to be preferable in various ways to that account, but actually to falsify it. We argue that this latter thought is rooted in a fundamental misunderstanding of the falsification-conditions of a family resemblance account; and we suggest that, once the reasons for this are appreciated, any apparent motivation to engage in relational theorizing about art evaporates.

Nietzsche’s psychological theory of the drives calls into question two common assumptions of ideology critique: 1) that ideology is fetishistic, substituting false satisfactions for true ones, and 2) that ideology is falsification; it conceals exploitation. In contrast, a Nietzschean approach begins from the truth of ideology: that capitalism produces an authentic contentment that makes the concealment of exploitation unnecessary. And it critiques ideology from the same standpoint: capitalism produces pleasures too efficiently, an overproduction of desire that is impossible to (...) sustain indefinitely. Nietzsche’s concept of the drives (Trieben) is grounded in his theory of the will to power. In contrast to Freud’s view that drives aim at satiation, pleasure through stimulus reduction, in Nietzsche’s view, they aim primarily at the “feeling of power” and the “happiness of high tension.” Nietzsche sees the desire for satiation as a symptom of weakness, a secondary, contingent aim that is incompatible with the fundamental drive to sustain and heighten the feeling of tension that accompanies strong desire. While the Freudian subject desires satisfaction, the Nietzschean subject is paradoxically frustrated by satisfaction, finding happiness in desire sustained by resistance and tension. If individuals desire desire as such, then exploitation and immiseration are not necessarily incompatible with their happiness. Consequently, we must reject the view that ideology is fetishistic: capitalism does not depend on an ersatz satisfaction in the commodity, a transferal of value from quality to quantity, use value to exchange value. Capitalism authentically satisfies desire precisely through its exploitative economic structure. The independence and unpredictability of the value of commodities and the immiseration of laborers produces discontents that enhance rather than frustrate desire. By continually introducing new, initially inaccessible commodities, then overcoming their inaccessibility through overproduction, capitalism sustains and intensifies desires. It promotes happiness not by satisfying wants but generating them, feeding the desire for desire, for the intensity of feeling that the brief pleasures of satiation would destroy. The commodity is not, then, a fetish, not a false satisfaction or aim, but a means, a prop that supports and sustains satisfaction as continued desire. Consequently, we must also reject the view that ideology is falsification: capitalism’s efficient production of happiness obviates the need to conceal its nature. Individuals tolerate capitalism not out of ignorance of exploitation but indifference to it; they prefer real happiness to a merely possible justice that might come at its expense. The critique of ideology must begin by acknowledging its truth. Rather than deny the real satisfactions of capitalism, it must demonstrate that they are unsustainable. (shrink)

Laboratory experimentation was once considered impossible or irrelevant in economics. Recently, however, economic science has gone through a real ‘laboratory revolution’, and experimental economics is now a most lively subfield of the discipline. The methodological advantages and disadvantages of controlled experimentation constitute the main subject of this thesis. After a survey of the literature on experiments in philosophy and economics, the problem of testing normative theories of rationality is tackled. This philosophical issue was at the centre of a famous controversy (...) in decision theory, during which a methodology of normative falsification was first articulated and used to assess experimental results. In the third chapter, the methodological advantages of controlled experimentation are illustrated and discussed with examples taken from the experiments on the so-called ‘preference reversal’ phenomenon. Laboratory testing allows to establish with a high degree of certainty that certain phenomena lie behind the experimental data, by means of independent testing, elimination of alternative hypotheses, and the use of different instruments of observation. The fourth chapter is devoted to a conceptual analysis of the problem of ‘parallelism’. This is the problem of inferring from the occurrence of a phenomenon in the laboratory, to its instantiation also in non-laboratory environments. Experimental economists have discussed parallelism at length, and their views are presented and criticised. Eventually, it is argued that parallelism is a factual matter and as such can only be established on empirical grounds. The fifth chapter provides an example of how one can argue for parallelism, focusing on the case of experimentation on the ‘winner’s curse’ phenomenon. The role of experiments as ‘mediators’ between theoretical models and their target domain of application is illustrated, and the structure of parallelism arguments analysed in detail. Finally, in the last chapter, economic experiments are compared to simulations, in order to highlight their specific characteristics. (shrink)

Popper argued that a statistical falsification required a prior methodological decision to regard sufficiently improbable events as ruled out. That suggestion has generated a number of fruitful approaches, but also a number of apparent paradoxes and ultimately, no clear consensus. It is still commonly claimed that, since random samples are logically consistent with all the statistical hypotheses on the table, falsification simply does not apply in realistic statistical settings. We claim that the situation is considerably improved if we (...) ask a conceptually prior question: when should a statistical hypothesis be regarded as falsifiable. To that end we propose several different notions of statistical falsifiability and prove that, whichever definition we prefer, the same hypotheses turn out to be falsifiable. That shows that statistical falsifiability enjoys a kind of conceptual robustness. These notions of statistical falsifiability are arrived at by proposing statistical analogues to intuitive properties enjoyed by exemplary falsifiable hypotheses familiar from classical philosophy of science. That demonstrates that, to a large extent, this philosophical tradition was on the right conceptual track. Finally, we demonstrate that, under weak assumptions, the statistically falsifiable hypotheses correspond precisely to the closed sets in a standard topology on probability measures. That means that standard techniques from statistics and measure theory can be used to determine exactly which hypotheses are statistically falsifiable. In other words: the proposed notion of statistical falsifiability both answers to our conceptual demands and submits to standard mathematical techniques. (shrink)

It is shown here that Suarez (Found. Phys. 38:583, 2008) wrongly presents the assumptions behind the Leggett’s inequalities, and their modified form used by Groeblacher et al. (Nature 446:871, 2007) for an experimental falsification of a certain class of non-local hidden variable models.

al-Tabarsī is one of the glossators in the Shī‘ah gloss tradition in the second middle period or first sagacity period. al-Tabarsī who had a wide knowledge in the various knowledge branches was mentioned as a glossator, narrator of Mohammad’s all sayings, deeds and approvals and scribe. One of compilations that al-Tabarsī wrote it in the field of gloss is Macmau-l-bayān fī tafsīri-l-Qur’ān. The glossator who widely included the recitations in this work used some evidence related to their averment while he (...) was reporting the recitations, and he made the recitations’ justification in the framework. The averment is a science which determines the correct recitations as distinguishing the correct one of recitation’s differences from the deficient one, and which founds an aspect of the correct category with all the other transferred and linguistic arguments of recitation in the predilection besides the imputation, the formal Qur’ān. Al-Tabarsī first mentioned the recitations under the subtitle of recitation related to the verses in each sura and then transferred the argument of recitations with the term of argument. So the glossator applied to give evidence on them with the linguistic and transferred arguments in each of the parts that the recitations were nearly mentioned. He mentioned the imputation, the Qur’ān lettering, verse, hadith, companion and natural people’s readings. He used Arabic poetry, Arabic idiom, dialect, grammar and syntax rules for the linguistic arguments. In this study, the evidences which were used in the recitations’ averment are reviewed in the sample of al-Tabarsī’s gloss in the name of Majmau-l-bayān. Summary: Full name of al-Tabarsī who was one of the leading scholar of Shī‘a is Fadl b. Hasan b Fadl al-Tabarsī. He was born in Thabaristan. According to some narration he was born in village named Tafrish which is between Kashan and Isfahan. He was called al-Tabarsī by reference to his hometown Thabaristan, according to another opinion he was called al-Tabarsī which comes from his birth place known as Tafrish located between Kashan and Isfahan. Tafrish was translated into Arabic as Tabars. Also, the commentator was known with nicknames such as Amīnü’l-islām, Amīnü’d-dīn and Umdatü’l-Mufassīrīn. He was called Sebzevarī due to the place where he died and named Maşhadī and Ṭūsī because of the place where he was buried. Although he is proficient in many fields, he has been described in the sources as commentator, muhaddīth and faqīh. Mufassīr has written many works in Islamic sciences. one of his works written in the field of commentary is Mujmau-l-bayān fī tafsīri-l-Qurʾān. Mufassīr stated that he wrote this commentary by taking advantage of Ṭūsī 's (d. 460/1067) al-Tibyān by saying “It is a guide from which I benefited from Tibiān light, and I write the subjects on the basis of his method”. The author started to write this work with the encouragement of some of his friends after he had aged quite a bit and his hair turned white. and he saw a gap in this area. He spent a lot of effort to fill that gap. This commentary, written during the first dirayet of the Shī‘a exegesis, is more moderate than the previous periods of Shī‘a commentators. The most basic indicator of this is the definitive rejection of the falsification of the Qurʾān in this period. The second important indicator is that insults and degrading expressions about the first three of the hulafā-i rashid and some of the companions are not accepted. The third important indicator is that most of the verses have been interpreted in a manner that corresponds to the views of the Ahl al-Sunnah school in linguistic analyses and proved by appealing to Arabic poems and sayings. al-Tabarsī mentioned recitation almost in all verses as a subtopic. He performed this in the surah by using subtopics. Then he has used “hujjatuhu” (its evidence) expression to narrate the evident of qirāʾāt. By doing so, commentator grounded qirāʾāts by using their evidences utilizing linguistic and narrative evidences in nearly every mentioned qirāʾāts. İhtijaj is a science that determines the authentic readings by distinguishing authentic readings from the weak ones, and that grounds the reading in the choice of an angle, which is mentioned in the authentic category, with isnād, Mushaf script and all other narrative and linguistic evidences. There are two types of ihtijaj which are ihtijaj bi-l-qirāʾāt ve ihtijaj li-l-qirāʾāt. İhtijaj li-l-qirāʾāt uses the linguistic evidences such as isnād, Mushaf line, Arabic language, consumables-nahiv pedestals, polish differences and the narrative evidences such as verses, hadith, qirāʾāt, Arabic words and poetry in determination and preference of a reading aspect. ihtijaj bi-l-qirāʾāt is the use of kıraa as evidence for any matter of science. al-Tabarsī has also mentioned detection proofs which reveal the authentic ways of qirāʾāt like isnād and rasm al-mushaf. Isnād is attribution to whom take the qirāʾāt from previous persons. This proportion reaches up to the Prophet. The persons in the chain of isnād constitute this chain. al-Tabarsī has given in preface the names of the recitors and narrators, which are famous in the cities, based on the fact that an authentic attribute is the basic element in the determination of the qirāʾāh. Thus he passed on the chains of isnād that reached up to the Prophet. Another thing that al-Tabarsī used in the determination proof of qirāʾāh is rasm al-mushaf. The commentator has used the spelling of al-mushaf scripture as evidence by saying “written in al-mushaf like this”. al-Tabarsī, also mentioned preferable evidences about ways of qirāʾā’s proof. Preferred proofs, are evidence to make choosing between qirāʾāh whose authenticity is defined by means of determination proofs. These evidences are divided into two parts which are determination proofs-based and special. Special evidence has not relation with the determination proofs. It contains evidence categories used to prefer one of the two authentic qirāʾāh as special. These categories are divided into four parts: linguistic, transplant, mental and private. al-Tabarsī has evidenced with verses of narrative proofs in the preferred evidence category. The commentator has mentioned about this method for qirāʾā evidence extensively. He has grounded qirāʾāh by using verses. al-Tabarsī also has evidenced these matters by using words of the Prophet from narrative proofs in the preferred evidence category. In this method commentator has evidenced from hadith after mentioning qirāʾāh ways. al-Tabarsī evidences from narrative proofs with qirāʾāh preferred evidence category. In this context, the commentator mentioned recitation of companion and followers by saying his qirāʾāh after reporting qirāʾāh. Moreover, the commentator has sometimes mentioned recitations which is related with reading seven of the recitation and reading ten of the recitation sciences qurra recitation and sometimes mentioned recitations which are known as shadhdh. Then, he has examined these recitations with the qirāʾāh of companions and followers. al-Tabarsī has benefited from narrative evidences, Arabic poetry and phrase in the preferred evidence category extensively. Another evidence used for examination of qirāʾāh is linguistic evidences. Qirāʾāh are related with Arabic language because it has connection with Qur’ānic wording which revelated in Arabic. al-Tabarsī has benefited from some things such as Arabic grammar rules and dialectic differences extensively. The commentator has benefited from Arabic grammar by emphasizing the meaning of the words with the literary features. He has explained grammar statement related with qirāʾāh aspects. He has also explained linguistic rules which are about aspects. (shrink)

This work inaugurates a critical inquiry into whether the ideas of Karl Popper, a philosopher of science, are used by astronomers and astrophysicists, a practicing community of scientists. It examines four basic components of Karl Popper's philosophy— falsification, prohibition, simplicity, and risk taking— and the extent that these themes become integrated into recent scientific literature on astronomy, astrophysics, cosmology, and stellar evolutionary theory. It concludes that the philosophy of science is highly relevant to the practice of astronomy, and that (...)

This is a response to a claim by Sven Ove Hansson to the effect that Poppers dictum that falsification lies at the heart of all pursuit of science has once and for all been falsified by his study of articles published in Nature during the year 2000.

We scrutinize (...) Hansson’s arguments as well as giving an overview of Poppers falsification theory. (shrink)

Falsification-aware (hyper)sequent calculi and Kripke semantics for normal modal logics including S4 and S5 are introduced and investigated in this study. These calculi and semantics are constructed based on the idea of a falsification-aware framework for Nelson’s constructive three-valued logic. The cut-elimination and completeness theorems for the proposed calculi and semantics are proved.

In this study, falsification-aware semantics and sequent calculi for first-order classical logic are introduced and investigated. These semantics and sequent calculi are constructed based on a falsification-aware setting for first-order Nelson constructive three-valued logic. In fact, these semantics and sequent calculi are regarded as those for a classical variant of N3. The completeness and cut-elimination theorems for the proposed semantics and sequent calculi are proved using Schütte’s method. Similar results for the propositional case are also obtained.

Dans ce travail, je vais m'efforcer de critiquer la thèse poppérienne de la dissymétrie entre les procédures de vérification et de réfutation des théories empiriques. Pour caractériser les théories empiriques, j'utiliserai le critère suivant: l'analyse des procédures discursives employées ne suffit pas comme base de discussion de leur valeur de vérité. On doit faire appel à quelque chose dont on considère que la donnée est en quelque façon, et du point de vue de la connaissance, extérieure à la théorie. Dans (...) le titre, j'ai employé «falsification» parce que c'était le terme habituel des traducteurs français de Popper jusqu'à une date récente.

Our starting point is Michael Luntley's falsificationist semantics for the logical connectives and quantifiers: the details of his account are criticised but we provide an alternative falsificationist semantics that yields intuitionist logic, as Luntley surmises such a semantics ought. Next an account of the logical connectives and quantifiers that combines verificationist and falsificationist perspectives is proposed and evaluated. While the logic is again intuitionist there is, somewhat surprisingly, an unavoidable asymmetry between the verification and falsification conditions for negation, the (...) conditional, and the universal quantifier. Lastly we are lead to a novel characterization of realism. (shrink)

We investigate the conflict between the ex ante and ex post criteria of social welfare in a new framework of individual and social decisions, which distinguishes between two sources of uncertainty, here interpreted as an objective and a subjective source respectively. This framework makes it possible to endow the individuals and society not only with ex ante and ex post preferences, as is usually done, but also with interim preferences of two kinds, and correspondingly, to introduce interim forms of the (...) Pareto principle. After characterizing the ex ante and ex post criteria, we present a first solution to their conflict that extends the former as much possible in the direction of the latter. Then, we present a second solution, which goes in the opposite direction, and is also maximally assertive. Both solutions translate the assumed Pareto conditions into weighted additive utility representations, and both attribute to the individuals common probability values on the objective source of uncertainty, and different probability values on the subjective source. We discuss these solutions in terms of two conceptual arguments, i.e., the by now classic spurious unanimity argument and a novel informational argument labelled complementary ignorance. The paper complies with the standard economic methodology of basing probability and utility representations on preference axioms, but for the sake of completeness, also considers a construal of objective uncertainty based on the assumption of an exogeneously given probability measure.

Efficient thinking is the foundation of efficient operation. The correct definition of concepts, especially the basic ones for a given field, in order to reach the truth, is a condition for the development of science and its social utility. The Petrażycki’s research methodology of law is a thoroughly modern method, as it enables effective examination of the accuracy of contemporary legal theories created after Petrażycki’s input. A model contemporary theory susceptible to an examination through the research methodology of law by (...) Petrażycki is the normative theory of legal rules and non-legal standards by Dworkin. For this purpose some falsifications will be subject, i.e. selected ad hoc among many others, two important theories of normative law theory Dworkin. The first one is the thesis classifying legal norms into two groups of norms, namely legal rules and non-legal standards. The second one is a thesis about the existence of who are capable of discovering and issuing lawful and, at the same time, fair court decisions, which are also the only ones for resolving particular court disputes. Unfortunately, owing to the seemingly cognitive research methodology of Petrażycki, both Dworkin’s deformed division of legal norms as well as Dworkin’s Hercules judges - cannot stand the test of authenticity. Due to the Petrażycki’s methodology, the legal-normative theory of Dworkin does not lose an innovative outlook on the existence of social norms, which are being discovered by judges in the jurisprudence, indifferently to the doubts over their proper classification. Moreover, Dworkin’s theory is placed between naive theories, regardless of whether they are considered realistically naive theories or nihilistically naive theories A few random reflections on the well-known work of Dworkin with the help of Petrażycki’s methodology serve to provide a new perspective on the contemporary legal normativity.

Gillies introduced a propensity interpretation of probability which is linked to experience by a falsifying rule for probability statements. The present paper argues that general statistical tests should qualify as falsification rules. The ‘goodness-of-fit paradox’ is introduced: the confirmation of a probability model by a test refutes the model's validity. An example is given in which an independence test introduces dependence. Several possibilities to interpret the paradox and to deal with it are discussed. It is concluded that the propensity (...) interpretation properly reflects statistical practice, but it is not as objective as some adherents claim. (shrink)

It has been suggested that the enterprise of developing mechanistic theories of the human cognitive architecture is flawed because the theories produced are not directly falsifiable. Newell attempted to sidestep this criticism by arguing for a Lakatosian model of scientific progress in which cognitive architectures should be understood as theories that develop over time. However, Newell's own candidate cognitive architecture adhered only loosely to Lakatosian principles. This paper reconsiders the role of falsification and the potential utility of Lakatosian principles (...) in the development of cognitive architectures. It is argued that a lack of direct falsifiability need not undermine the scientific development of a cognitive architecture if broadly Lakatosian principles are adopted. Moreover, it is demonstrated that the Lakatosian concepts of positive and negative heuristics for theory development and of general heuristic power offer methods for guiding the development of an architecture and for evaluating the contribution and potential of an architecture's research program.

Summary In two articles Friedrich Rapp argues that there is a methodological symmetry between falsification and verification in contradistinction to the logical asymmetry that obtains between them. (The Methodological Symmetry between Verification and Falsification,Ztschr. f. Allg. Wissth., Band VI/1 (1975), pp 139–144; A Helpful Argument — Reply to K. Eichner,Ztschr. f. Allg. Wissth., Band VII/1 (1976), pp. 121–123). Rapp puts forward the thesis that methodological falsification of a theory T implies the acceptance of an inference from ~ (...) (x) Tx to (x) ~ Tx. However, this thesis does not have to be accepted even if the premises of Rapp's argument were accepted. Furthermore, Rapp has not shown that the falsification of a theory T implies that T will not be retained. Neither has Rapp formulated assumptions that are sufficient to guarantee that the outcome of an intended test of a theory T can be considered as an outcome of an actual test of T. (shrink)

I distinguish several doctrines that economic methodologists have found attractive, all of which have a positivist flavour. One of these is the doctrine that preference assignments in economics are just shorthand descriptions of agents' choice behaviour. Although most of these doctrines are problematic, the latter doctrine about preference assignments is a respectable one, I argue. It doesn't entail any of the problematic doctrines, and indeed it is warranted independently of them.

Recent discussion of the problem of the conclusive falsification of scientific hypotheses has generally regarded the Duhemian Thesis (D-Thesis) as both true and interesting [10] but has dismissed the claim that disconfirmed hypotheses can be retained in explanations of the disconfirming evidence as either trivial [3] or unargued [12]. This paper rejects these positions. First, the status, in the argument for the D-Thesis, of the claim that auxiliary assumptions are necessary for the derivation of evidential propositions from hypotheses is (...) examined. It is concluded that depending on this status, the D-Thesis is either trivially true or unargued. Then the retention of contextually disconfirmed hypotheses is discussed. It is found that the use of such hypotheses in explanations of the disconfirming evidence is mediated by principles of scientific methodology. A new thesis is presented connecting the problem of conclusive falsification with changes in methodology. The argument for this thesis introduces a new analysis of methodological principles as inductive generalizations from scientific practice. Finally, the contribution of this analysis to the understanding of scientific change is described. (shrink)

Contemporary empiricism has attempted to ground its analysis of science in a falsificationism based in selection theory. This paper links these evolutionary epistemologies with commitments to certain epistemological and ontological assumptions found in the later work of K. Popper, D. Campbell, and D. Hull, I argue that their assumptions about the character of contemporary empiricism are part of a shared paradigm of epistemological explanation which results in unresolved tensions within their own projects. I argue further that their claim to be (...) doing a science of science is not defensible. Hull's selectionism is analyzed to show how this epistemological agenda has played itself out in late empiricism. I suggest some directions that Hull might take toward an historical epistemology.

This paper reconsiders the possibility of applying the procedure of falsification, which consists in testing a theory by confronting hypotheses derived from the theory with empirical data, in the studies of culture, in particular when evaluating interpretive hypotheses. Falsification, to which, according to Popper and his followers, the natural sciences owe their success, is viewed with strong suspicion when the object of investigation is meanings and values rather than material phenomena. If by interpretation one understands reconstruction of the (...) artefact’s meaning, obvious challenges when falsifying interpretive hypotheses include: the multiplicity, instability and ambiguity (indefiniteness or self-contradictory character) of meanings inherent in artefacts. All of this does not seem to exclude the possibility of identifying as misreadings interpretive hypotheses which clearly contradict relevant (non-contradictory) artefactual evidence. Falsification thus understood seems indispensable in educational contexts. At the same time, it must be admitted that in practice (as contrasted with the logical formula which underlies the procedure) falsification is inconclusive, and the application of the procedure is further complicated when meanings and values are the object of research. This is one of the reasons why falsification in the humanities (as elsewhere) needs to be complemented by other epistemic procedures while the status of literary studies or history of philosophy might best be perceived as partly cognitive (and in so far as the research conducted in these disciplines is empirically testable, also scientific) and partly creative (artistic).

The main result of this paper is that KT is closed under a cancellation principle. This result extends to KTG1, but it does not extend to modal systems associated with the provability interpretation of L, such as KW and KT4Grz. Following Williamson, these results are applied to philosophical concerns about the proper form for theories of meaning, via the interpretation of L as some kind of veriflability. The cancellation principle can then be read as saying that verifilability conditions and falsiflability (...) conditions jointly determine truth conditions. (shrink)

Scientists have rules pertaining to data fabrication and falsification that are enforced with significant punishments, such as loss of funding, termination of employment, or imprisonment. These rules pertain to data that describe observable and unobservable entities. In this commentary I argue that scientists would not adopt rules that impose harsh penalties on researchers for data fabrication or falsification unless they believed that an aim of scientific research is to develop true theories and hypotheses about entities that exist, including (...) unobservable ones. This argument presents a challenge for constructive empiricists, such as van Fraassen. Constructive empiricists need to be able to explain why rules pertaining to data fabrication and falsification do not threaten their philosophy of science. (shrink)

Sequel to Armendt 1986, ‘A Foundation for Causal Decision Theory.’ The representation theorem for causal decision theory is slightly revised, with the addition of a new restriction on lotteries and a new axiom (A7). The discussion gives some emphasis to the way in which appropriate K-partitions are characterized by relations found among the agent’s conditional preferences. The intended interpretation of conditional preference is one that embodies a sensitivity to the agent’s causal beliefs.

The famous story of Diogenes searching for a man (ánthrōpon zētō̂) with his lantern in broad daylight (D.L. VI 41) has been interpreted in two ways, according to the meaning assigned to the word ánthrôpos (« human »). Proponents of the nominalist interpretation, by giving it the sense of human as a concept, see in the quest of Diogenes an attack against Plato’s Ideas. Defenders of the moral interpretation rather give the word ánthrôpos a concrete meaning with meliorative value: Diogenes (...) is searching in vain for a virtuous human. After showing that both interpretations are equally valid, our paper argues for a middle way, called the « falsification of language », which reconciles the two positions through an analysis of the relationship between language and truth in the Cynics.
