There is a great deal of justified concern about continuity through scientific theory change. Our thesis is that, particularly in physics, such continuity can be appropriately captured at the level of conceptual frameworks using conceptual space models. Indeed, we contend that the conceptual spaces of three of our most important physical theories—Classical Mechanics, Special Relativity Theory, and Quantum Mechanics —have already been so modelled as phase-spaces. Working with their phase-space formulations, one can trace the conceptual changes and continuities in transitioning (...) from CM to QM, and from CM to SRT. By offering a revised severity-ordering of changes that conceptual frameworks can undergo, we provide reasons to doubt the commonly held view that CM is conceptually closer to SRT than QM. (shrink)

In a legendary technical report, the Google founders sketched a wisdom-of-crowds justification for PageRank arguing that the algorithm, by aggregating incoming links to webpages in a sophisticated way, tracks importance on the web. On this reading of the report, webpages that have a high impact as measured by PageRank are supposed to be important webpages in a sense of importance that is not reducible to mere impact or popularity. In this paper, we look at the state of the art regarding (...) the more precise statement of the thesis that PageRank and other similar in-link-based ranking algorithms can be justified by reference to the wisdom of crowds. We argue that neither the influential preferential attachment models due to Barabási and Albert in nor the recent model introduced by Masterton et al. in allows for a satisfactory wisdom-of-crowds justification of PageRank. As a remedy, we suggest that future work should explore “dual models” of linking on the web, i.e., models that combine the two previous approaches. Dual models view links as being attracted to both popularity and importance. (shrink)

Social epistemology studies knowledge and justified belief acquisition through organized group cooperation. To do this, the way such group cooperation is structured has to be modeled. The obvious way of modeling a group structure is with a directed graph; unfortunately, most types of social cooperation directed at epistemological aims are variably implementable, including in their structural expression. Furthermore, the frequency with which a practice is implemented in a certain way can vary with topology. This entails that the topology of social (...) practices directed toward epistemological ends has to be modeled by a set of directed graphs, or their equivalent, together with a probability distribution over that set. In theory, this is eminently possible; however, there are considerable practical obstacles to the specification of a practice’s topology in this way. This paper examines these practical difficulties and concludes that todays sampling protocols are either far too slow to handle pratices with 10 or more participants, or else prone to produce misleading evaluations.

We address the fundamental question why we should use PageRank and similar link-based algorithms in search engines, if at all. In a legendary article from 1998, the Google founders gave an intriguing wisdom-of-crowds justification for PageRank according to which the latter tracks quality online. This striking suggestion stands in contrast to the view that PageRank merely tracks what is popular. However, Masterton and Olsson showed that web-ecologies generated by Google-like assumptions essentially fail to reflect the scale-free structure of the (...) web. They pointed to attraction to popularity or a rich-get-richer effect being the likely main cause of scalefreeness. In this article, we explore dual models of linking behavior, i.e. models that combine attraction to importance with attraction to popularity. Our results, obtained through computer simulation, indicate that there exist dual models that give rise both to a wisdom-of-crowds effect for PageRank and to scale-free web-graphs, thus giving a partial vindication of the wisdom-of-crowds thesis for the real web. Future work should explore larger web-graphs as well as other aspects pertaining to the empirical plausibility of dual linking models. (shrink)

The very last of words of Naming and Necessity are ‘The third lecture suggests that a good deal of what contemporary philosophy regards as mere physical necessity is actually necessary tout court. The question how far this can be pushed is one I leave for further work.’ Kripke (1980). To my knowledge he never conducted that further work; moreover, no one following him has wished to take up the baton either. Herein, I argue that in general, physical necessity is neither (...) reducible to, nor implies, tout court necessity. Furthermore, it is demonstrated that even if Kripke’s speculations are restricted to a subset of the physical necessities where it might be granted that all such are necessary tout court, physical necessity is still not reducible to tout court necessity.

According to Williamson , the difference between empirical subjective Bayesians and objective Bayesians is that, while both hold reasonable credence to be calibrated to evidence, the objectivist also takes such credence to be as equivocal as such calibration allows. However, Williamson’s prescription for equivocation generates constraints on reasonable credence that are objectionable. Herein Williamson’s calibration norm is explicated in a novel way that permits an alternative equivocation norm. On this alternative account, evidence calibrated probability functions are recognised as implications of (...) evidence calibrated density functions defined over chance hypotheses. The objective Bayesian equivocates between these calibrated density functions rather than between the calibrated probability functions themselves. The result is an objective Bayesianism that avoids the main problem afflicting Williamson’s original proposal. (shrink)

Book review of Jon Williamson's `In Defence of objective Bayesianism'.

In 1977 van Fraassen showed convincingly, and in detail, how one can give a dissentive answer to the question `[a]re there necessities in nature?'. In this paper I follow his lead and show in a similar fashion and detail, how it is possible to give a dissentive answer to: Are there probabilities in nature? This is achieved by giving a partial analysis—with the aid of Kaplanian pragmatics—of objective chance in terms of that credence that is reasonable where prevailing laws and (...) conditions exhaust one's evidence. This template belongs firmly within the established Bayesian program of analysing objective chance as ultimate belief. Its contribution to that program is the same as van Fraassen's contribution to the empiricist program of analysing physical necessity; namely, it demonstrates the logical possibility of such an analysis.

Lewis' concept of admissibility was introduced as an integral part of his famous Principal Principle; the principle that initial rational/reasonable belief should conform to objective chance unless there is evidence to the contrary. At that time Lewis offered only the rough and ready characterisation that evidence not to the contrary of such dependence is admissible. This, together with some sufficiency conditions, served well enough until it became clear that admissibility was central to debates on the viability of Humean Supervenience and (...) the analysis of objective chance. In response, Thau and Lewis refined the concept of admissibility in various ways. Since the mid 90's those who have employed the concept have, with minor variations and additions, followed the Thau/Lewis line. Yet, in the 30 years since its introduction what has been all too conspicuous by its absence is a full formal definition of admissibility and its degrees. Herein a family of definitions—all in terms of screening off by chance—that capture much that has been agreed about admissibility are proposed and evaluated; one of which is ultimately found to be serviceable as a definition schema for relative admissibility and its degrees.

In the literature one finds two non-equivalent responses to forecasts; deference and updating. Herein it is demonstrated that, under certain conditions, both responses are entirely determined by one’s beliefs as regards the calibration of the forecaster. Further it is argued that the choice as to whether to defer to, or update on, a forecast is determined by the aim of the recipient of that forecast. If the aim of the recipient is to match their credence with the prevailing objective chances, (...) they should defer to the forecast; if it is to maximize the veritistic value of their beliefs, they should update on the forecast. (shrink)

Objective Bayesians hold that degrees of belief ought to be chosen in the set of probability functions calibrated with one’s evidence. The particular choice of degrees of belief is via some objective, i.e., not agent-dependent, inference process that, in general, selects the most equivocal probabilities from among those compatible with one’s evidence. Maximising entropy is what drives these inference processes in recent works by Williamson and Masterton though they disagree as to what should have its entropy maximised. With regard (...) to the probability function one should adopt as one’s belief function, Williamson advocates selecting the probability function with greatest entropy compatible with one’s evidence while Masterton advocates selecting the expected probability function relative to the density function with greatest entropy compatible with one’s evidence. In this paper we discuss the significant relative strengths of these two positions. In particular, Masterton’s original proposal is further developed and investigated to reveal its significant properties; including its equivalence to the centre of mass inference process and its ability to accommodate higher order evidence.

Queen Christina of Sweden was unconventional in her time, leading to hypotheses on her gender and possible hermaphroditic nature. If genetic analysis can substantiate the latter claim, could this bring the queen into disrepute 300 years after her death? Joan C. Callahan has argued that if a reputation changes, this constitutes a change only in the group of people changing their views and not in the person whose reputation it is. Is this so? This paper analyses what constitutes change and (...) draws out the implications to the reputation of the dead. It is argued that a reputation is a relational property which can go through changes. The change is “real” for the group changing their views on Queen Christina and of a Cambridge kind for the long dead queen herself. Cambridge changes result in new properties being acquired, some of which can be of significance. (shrink)

Idealist philosopher Georg Hegel defied the traditional epistemological distinction of objective from subjective and developed his own dialectical alternative. Remarkable for its breadth and profundity, this work combines aspects of psychology, logic, moral philosophy, and history to form a comprehensive view that encompasses all forms of civilization. Its three divisions consist of the subjective mind (dealing with anthropology and psychology), the objective mind (concerning philosophical issues of law and morals), and the absolute mind (covering fine arts, religion, and philosophy). Wide-ranging (...) in its influence, this survey of the evolution of consciousness is essential reading for all students of philosophy and history. (shrink)

The topic of a priori knowledge is approached through the theory of evidence. A shortcoming in traditional formulations of moderate rationalism and moderate empiricism is that they fail to explain why rational intuition and phenomenal experience count as basic sources of evidence. This explanatory gap is filled by modal reliabilism -- the theory that there is a qualified modal tie between basic sources of evidence and the truth. This tie to the truth is then explained by the theory of concept (...) possession: this tie is a consequence of what, by definition, it is to possess (i.e., to understand) one’s concepts. A corollary of the overall account is that the a priori disciplines (logic, mathematics, philosophy) can be largely autonomous from the empirical sciences. (shrink)

This important new work surveys the source and ramifications of the famed Nuremburg Code -- recognized around the world as one of the cornerstones of modern bioethics.

With the advanced methods of analysing old biological material, it is pressing to discuss what should be allowed to be done with human remains, particularly for well documented historical individuals. We argue that Queen Christina of Sweden, who challenged the traditional gender roles, has an interest in maintaining her privacy when there are continued attempts to reveal her ‘true’ gender. In the long-running philosophical debate on posthumous wronging, the fundamental question is: Who is wronged? Our aim is to find this (...) ‘missing subject’ using narrative theory.Narrative identity emphasises the fact that no person is alone in knowing or telling their life story. People’s lives are entangled and parts of the life story of a deceased person can remain in the living realm. Since the narrative identity of a person does not necessarily end upon their death, and this narrative continues to relate directly to the person who once existed, it is the narrative subject that can continue to be posthumously wronged. Queen Christina can no longer maintain her own identity, but we maintain it by our research into her life. We propose three duties relevant for posthumous wronging: the duty of truthfulness, the duty of recognition and the duty to respect privacy. (shrink)

In medical research, patients are increasingly recognized with ‘lay knowledge’ but their views are poorly researched. The study objective was to investigate patients’ attitudes to medical research. This is in comparison to lay and expert members on ethical review boards, as their task is to evaluate the risk−benefits of research, which are ultimately grounded in attitudes and values. From focus-group interviews with patients suffering from chronic inflammatory diseases, a postal questionnaire was developed and sent to patient members of the Swedish (...) Rheumatism Association and to all ERB board members in Sweden. Response rates were 65 percent and the surveys were conducted in Jan−May 2011. Agreement across the groups included priority for medical research on diagnostic and early detection of disease. A key difference was expert and lay ERB members giving higher priority to basic research/research on lifestyle and prevention, whereas patients prioritized research on daily function. On this significant point, lay members did not share the opinion of this patient group, indicating that they may be poor representatives for patients’ views. These results call for further research: how can patient perspectives be included in ERB discussions and in what way should patients’ values influence the research agenda. (shrink)

Functionalism would be mistaken if there existed a system of deviant relations (an “anti-mind”) that had the same functional roles as the standard mental relations. In this paper such a system is constructed, using “Quinean transformations” of the sort associated with Quine’s thesis of the indeterminacy of translation. For example, a mapping m from particularistic propositions (e.g., that there exists a rabbit) to universalistic propositions (that rabbithood is manifested). Using m, a deviant relation thinking* is defined: x thinks* p iff (...) x thinks m(p). Such deviant relations satisfy the commonly discussed functionalist psychological principles. Finally, a more complicated system of deviant relations is constructed, one satisfying sophisticated principles dealing with the self-conscious rational mind. (shrink)

George Berkeley (1685-1753) is the superstar of Irish Philosophy. He entered Trinity College, Dublin, in 1700 and became a fellow in 1707. In 1724 he resigned his Fellowship to become Dean of Derry, and in 1734 he was made Bishop of Cloyne. He settled in Oxford in 1752 and died the following year. The work of George Berkeley is marked by its diversity and range. His writings take in such topics as mathematics, psychology, politics, health, economics, deism and (...) education, as well as that with which he is most associated - philosophy. Whatever topic he dealt with, his grasp of the subject matter was always impressive and his criticisms of his contemporaries often acute. Among the most noteable of the British Empiricists, he took his starting point from Locke's new 'way of ideas', but he rejected abstract ideas and the possibility of real existence outside perception. It is for this doctrine that he is most known - that there is no such thing as matter, and that things are collections of ideas which can exist only in our minds and only for so long as they are perceived. This philosophy, summed up in his phrase 'to be is to be perceived', he termed 'immaterialism'. A.C. Fraser's collection includes a series of what were previously unpublished notes by Berkeley on all the main topics of his philosophy. This, the 1901 edition, was the first complete edition of his works. (shrink)

Georges Sorel's Study on Vico is a revelatory document of the depths and stakes of French social thought at the end of the 19th century. What brought Sorel to the 18th century Neapolitan theorist of history? Acute awareness of the limitations of Marxist thought in his day, a profound concern with the material underpinnings of language, law, and culture, and the imperative to understand the possibilities of revolutionary change. We find here a different Sorel, one who speaks in surprising ways (...) to the 21st century. The translation is accompanied by an introduction and by a set of notes which situate the text both in Sorel's overall intellectual trajectory and in the fin de siècle debates from which it emerged.

What drives much of the current philosophical interest in the idea of group cognition is its appeal to the manifestation of psychological properties—understood broadly to include states, processes, and dispositions—that are in some important yet elusive sense emergent with respect to the minds of individual group members. Our goal in this paper is to address a set of related, conditional questions: If human mentality is real yet emergent in a modest metaphysical sense only, then: (i) What would it mean for (...) a group to have emergent cognitive states? (ii) Is this even a metaphysically coherent view? (iii) Relative to which notion of emergence do we have reason to believe that certain groups in fact have emergent cognitive states? We shall argue that evidence from a wide variety of social science domains makes it plausible that there are group cognitive states and processes no less metaphysically emergent than human cognitive (and other special science) states and processes.

In the light of two unpublished letters from Carnap to Kuhn, this essay examines the relationship between Kuhn's The Structure of Scientific Revolutions and Carnap's philosophical views. Contrary to the common wisdom that Kuhn's book refuted logical empiricism, it argues that Carnap's views of revolutionary scientific change are rather similar to those detailed by Kuhn. This serves both to explain Carnap's appreciation of The Structure of Scientific Revolutions and to suggest that logical empiricism, insofar as that program rested on Carnap's (...) shoulders, was not substantially upstaged by Kuhn's book.

Stolen Legacy by George G.M. James refutes the Euro-centric myth that the origin of Western philosophy is Greek. First published in 1954, this book was seminal in leading to a radical reappraisal of a philosophical system long thought to be of European origin. It is an essential work in the syllabus for the study of Western philosophy.

How do we evaluate the power and utility of language when it has been made to articulate falsehoods in certain totalitarian regimes or has been charged with vulgarity and imprecision in a mass-consumer democracy? How will language react to the increasingly urgent claims of more exact speech such as mathematics and symbolic notation? These are some of the questions Steiner addresses in this elegantly written book, first published in 1967 to international acclaim.
