The debate about the relative epistemic weights carried in favour of a theory by predictions of new phenomena as opposed to accommodations of already known phenomena has a long history. We readdress the issue through a detailed re-examination of a particular historical case that has often been discussed in connection with it-that of Mendeleev and the prediction by his periodic law of the three 'new' elements, gallium, scandium and germanium. We find little support for the standard story that these predictive (...) successes were outstandingly important in the success of Mendeleev's scheme. Accommodations played an equal role-notably that of argon, the first of the 'noble gases' to be discovered; and the methodological situation in this chemical example turns out to be in interesting ways different from that in other cases-invariably from physics-that have been discussed in this connection. The historical episode when accurately analysed provides support for a different account of the relative weight of prediction and accommodation-one that is further articulated here. (shrink)

In a lengthy article E. Scerri and J. Worrall put forward the case for a novel ‘accommodationist’ version of the events surrounding the development of Mendeleef's Periodic Table 1869–1899. However these authors lay undue stress on the fact that President of the Royal Society of London Spottiswoode made absolutely no mention of Mendeleef's famous predictions in the Davy Medal eulogy in 1883 and undue stress on the fact that Cleve's classic 1879 Scandium paper contained an acknowledgement of Mendeleef's prior prediction (...) of eka-boron.They also fail to analyse in any detail the so-called ‘rare earth problem’ which, in the opinion of this author, causes problems for their account but not for a predictivist account.

In this paper I comment on a recent paper by [Scerri, E., & Worrall, J. . Prediction and the periodic table. Studies in History and Philosophy of Science, 32, 407–452.] about the role temporally novel and use-novel predictions played in the acceptance of Mendeleev’s periodic table after the proposal of the latter in 1869. Scerri and Worrall allege that whereas temporally novel predictions—despite Brush’s earlier claim to the contrary—did not carry any special epistemic weight, use-novel predictions did indeed contribute to (...) the acceptance of the table. Although I agree with their first claim, I disagree with their second. In order to spell out my disagreement, I not only revisit Scerri and Worrall’s interpretation of crucial historical evidence they have cited in support of the ‘heuristic account’ of use-novel predictions, but I also criticise the latter on general grounds.Keywords: Periodic table; Dmitri Mendeleev; Noble gases; Use-novel predictions; Heuristic account; Ad hoc hypotheses.

This review provides an outline of the collection New Approaches to Scientific Realism, edited by Wenceslao Gonzalez. In particular, it questions whether the contributions to this edition can claim to be novel. The edition includes an introductory chapter and eighteen texts by well-known philosophers, such as Peter Achinstein, Alexander Bird, Donald Gillies, Theo Kuipers, Alan Musgrave, Thomas Nickles, Ilkka Niiniluoto, Howard Sankey, and John Worrall.

Summary: Responding to Laudan’s skeptical reading of history an influential group of realists claim that the seriously wrong claims past successful theories licensed were not really implicated in the predictions that once singled them out as successful. For example, in the case of Fresnel’s theory of light, it is said that although he appealed to the ether he didn’t actually need to in order to derive his famous experimental predictions—in them, we are assured, the ether concept was “idle,” “inessential,” “peripheral” (...) or worse. This view, developed by J. Worrall and P. Kitcher in the 1980s and subsequently supplemented by J. Leplin and by S. Psillos has received critical attention in the literature over the last decade, but more needs to be said on the subject—or so I suggest in this paper. I bring forward four converging argumentative lines to show how and why, from the days of Fresnel to at least the decade after the Michelson-Morley experiments, the ether functioned and was understood as an “essential” posit in physics. My first line draws Fresnel’s actual deployment of the ether concept and the way he and his circle understood the achievements of his theory. The second line draws is from epistemological assessments of surprising implication in theories and its impact on leading theorists in the last two-thirds of the century. The third line draws from discussions of the optical ether in end-of-century reports circa 1900. The fourth focuses on entrenched metaphysical assumptions that persisted in the practice of physics until the advent of special relativity. Pulling these four lines together shows, I think, why attempts at synchronic identification of sound theory-parts are bound to fail, and also how realists might try to meet the challenge this creates.

The paper discusses the sense in which the changes undergone by normative economics in the twentieth century can be said to be progressive. A simple criterion is proposed to decide whether a sequence of normative theories is progressive. This criterion is put to use on the historical transition from the new welfare economics to social choice theory. The paper reconstructs this classic case, and eventually concludes that the latter theory was progressive compared with the former. It also briefly comments on (...) the recent developments in normative economics and their connection with the previous two stages.

In the last decades there was a structural turn in the classic debate between scientific realists and antirealists with empiricist orientation. Two main arguments support the realist conception: the ‘No Miracle Argument’ and the thesis of continuity. The thesis of continuity states that some parts of a theory are retained when a scientific change takes place. In a current famous article, J. Worrall defends the continuity argument by stating that what is preserved in the succession of two empirically successful theories (...) are the relations among the postulated entities and not the nature of the relata. Based on this perspective, van Fraassen introduces his position named Empiricist Structuralism, which claims that only the structures of phenomena are retained. This conception tries to explain the success of science and at the same time defend the continuity of structures. I will demonstrate in this paper that the accomplishment of the two mentioned requirements imply a capitulation in favor of realistic intuitions. (shrink)

The subject of this article is to discuss epistemological issues related to the pro-cess of obtaining empirical evidence in medicine. This paper will present how N. Cartwright, J. Worrall and P. Urbach describe the function of the randomisation pro-cedure in this process. Based on these findings, it will be possible to define an alter-native method of obtaining empirical evidence for the purpose of making clinical decisions. This method involves data analysis using the Rough Set Theory proposed by Z. Pawlak. By (...) applying this method, a deterministic algorithm for making clinical decisions can be formulated. Being an interesting alternative to statistical approaches that dominate in medicine, the RST method generates specific epistemological problems. Therefore, it seems to constitute an interesting subject of analysis for philosophers of science. (shrink)

J. Ladyman, Ladyman and Ross refine J. Worral's structural realism, by developing an ontic structural realism which they argue is a consistently naturalistic means of characterizing the ontology of fundamental physics. I argue that elements of analytic metaphysics strengthen and refine their project of characterizing fundamental physics via OSR and by extension, their presentation of information-theoretic structural realism. I refine this point by situating M. Lange’s discussion of nomological modality qua natural necessity within Ladyman and Ross’s discussion of ITSR. (...) The logical hierarchy evinced in Lange’s ‘nomic stability’ further extends and refines Ladyman and Ross’s claims through the addition of nuanced modal distinctions in a systematic framework.

I demonstrate this point by situating M. Lange’s discussion of nomological modality and natural necessity within Ladyman and (...) Ross’s discussion of ITSR. The logical hierarchy evinced in Lange’s notion of ‘nomic stability’ further refines Ladyman and Ross’s claims through the addition of nuanced modal distinctions in a systematic framework. Moreover, I argue that what Lange considers are the ‘lawmakers’ serve as a de dicto rendition of some of Ladyman & Ross’s fundamental de re extensions and refinements of ‘real patterns’. (shrink)

Thucydides, II. 28, records an eclipse of the sun in the summer of the first year of the Peloponnesian war. It can be no other than the annular eclipse of the 3rd of August, 431 B.C. He describes the phenomenon so accurately and with so many details that we can hardly doubt that he observed it himself — Tο δ' αủτο θέρονς γονμηνι κατά σελήγηγ, σπερ και μόγογ δοκει ειναι γιγνεσθαι δνγατόγ, ό λιος έξέλιπε μετά μεσημβριαγ και πάλιγ άγ επληρθη, (...) γενόμενος μηνοειδής και άστέρν τινν έκΦανέντων.

Levinas and other contemporary thinkers have claimed that the philosophy of "the other" provides a devastating critique of systematic rationality as such and of Hegel as a paradigm case thereof.The critique links an ethical moment and socio-political issues to a thorough-going critique of Hegelian metaphysics and the dialectical method. I articulate the meaning of alterity as a critique of Hegel through Levinas and Marx, and then discuss possible Hegelian responses to this criticism. I conclude that this critique of Hegel pertains (...) to the character of his final synthesis rather than to questions of difference and identity, and challenge the interpretation of Hegelian closure as the realization of eschatology.

The term "stakeholder engagement" has gained increasing prominence over the last few years. This prominence is fueled by a range of issues such as an increased dissatisfaction with business's focus on stockholder/shareholder interests and the demands for greater transparency from business following major business scandals. A perceived response to this issue in South Africa has been the inclusion of guidelines on stakeholder engagement in the King II Report on Corporate Governance. Despite this growing interest, there has not been clarity on (...) how companies engage with their stakeholders and specifically with how they identify and prioritize their stakeholders. The study sought to establish the reporting practices of South African business in relation to stakeholder identification and prioritization through a content analysis of their annual reports. The findings are discussed and recommendations on the two aspects of stakeholder engagement presented. (shrink)
