The manuscripts and writings of the fifteenth-century astronomer and physician Lewis Caerleon (d. c. 1495) have been largely overlooked. To fill this gap, this article focuses on his writings and working methods through a case study of his canons and table for the equation of time. In the first part, an account of his life and writings is given on the basis of new evidence. The context in which his work on the equation of time was produced is explored in (...) detail by reviewing the three key periods of his scientific production. His heavy reliance on Simon Bredon’s Commentum super Almagesti is also analyzed. The article also provides editions of Lewis Caerleon’s canons for calculating his table for the equation of time and a critical edition of Simon Bredon’s Commentum super Almagesti, III, 22–24. In the second part of this article, we analyze the table for the equation of time derived by Lewis around 1485. In addition to the final table, there is a unique table with intermediate results that records every step of his derivation. By following and discussing the details of this derivation, we shed a new light on tabular practices in mathematical astronomy. Following Lewis in his historical mathematical procedure, we argue, offers a novel historiographical approach that allows us to identify different sources and practices used by historical actors. Therefore, beyond the exchange of parameters residing in modern mathematical analysis, this novel approach offers a promising refinement for the analysis of the transmission of knowledge across space, time, and culture.

The dissertation provides a reconstruction of Bernard Bolzano's theory of grounding (both in early and late works) against the background of a classical conception of science and scientific explanation.

Argues that content-independent reasons are intentions. Relies on Grice's distinction between natural and non-natural meaning. Rejects previous accounts, and argues that his account can understand the force of such reasons appropriately, through the conept of enabling-conditions. Illustrates through several paridigmatic types of content-independent reasons.

The ocean’s properties and processes are now mostly known through distributed sensor networks. Among the most widespread of such networks are those that connect wave-measuring buoys. Buoys have been deployed and consulted by national meteorological organizations, state militaries, multinational corporations, and citizens. This paper zeroes in on the Directional Waverider, the most widely used buoy, manufactured since 1961 in the Netherlands by Datawell. I am interested in this buoy’s material qualities and networks of use, its life within legal frameworks, and (...) its media ecology. Staging my account against the metaphysical Italian author Italo Calvino’s “Reading a Wave,” I explore what it means to “read” a sensing technology. (shrink)

RésuméLes modernistes arabes et les humanistes occidentaux considèrent souvent le philosophe musulman Averroès comme l’un des premiers précurseurs de Kant et des Lumières européennes. Contrairement à cette réputation, cet article soutient que ce sont les critiqueurs de Kant, Herder et Tiedemann, qui ont redécouvert Averroès. Tiedemann a été le premier historiographe allemand à donner un compte rendu précis de la pensée d’Averroès. Cela s’est accompagné d’une réévaluation d’Averroès par Herder dans ses Lettres sur les progrès de l’humanité, dans lesquelles il (...) reconnaît la similitude entre son propre concept de l’esprit du temps en tant que raison historique – son alternative au concept des Lumières d’une raison universelle et anhistorique – et le concept d’Averroès d’un intellect matériel unique pour tous les esprits humains individuels. Enfin, l’article expose les liens possibles entre l’interprétation d’Averroès de l’intellect d’Aristote et le concept de raison historique de Hegel. (shrink)

The goal of behavioral economics is to improve the explanatory and predictive power of economics. This can be achieved by using theoretical and methodological resources of psychology. Its fundamental idea is that the relationship between psychology and economics cannot be subsumed under standard philosophical accounts of intertheoretical relations. Philosophical Problems of Behavioral Economics argues that behavioral economics is best understood as an attempt to deidealize economic theory guided by psychological research. Behavioral economics deconstructs the model of decision-making by adding different (...) elements. Based on this understanding behavioral economics has a number of tasks: first, it has to identify which economic theory needs to be challenged; second it aims to identify factors which need to be modelled within economic theories of choice and modify the theory accordingly; and finally, it has to create models that explain economic phenomena based on the new theory. This book analyses the different stages of this deconstruction process and shows how the scientific disciplines of economics and psychology are connected by it. This volume develops a new account of intertheoretical relations based on the idea of deidealization and thus contributes to debates within the philosophy of social science. It is suitable for those who are interested in or study economic theory and philosophy, economic psychology and philosophy of social science. (shrink)

Let us by ‘first-order beliefs’ mean beliefs about the world, such as the belief that it will rain tomorrow, and by ‘second-order beliefs’ let us mean beliefs about the reliability of first-order, belief-forming processes. In formal epistemology, coherence has been studied, with much ingenuity and precision, for sets of first-order beliefs. However, to the best of our knowledge, sets including second-order beliefs have not yet received serious attention in that literature. In informal epistemology, by contrast, sets of the latter kind (...) play an important role in some respectable coherence theories of knowledge and justification. In this paper, we extend the formal treatment of coherence to second-order beliefs. Our main conclusion is that while extending the framework to second-order beliefs sheds doubt on the generality of the notorious impossibility results for coherentism, another problem crops up that might be no less damaging to the coherentist project: facts of coherence turn out to be epistemically accessible only to agents who have a good deal of insight into matters external to their own belief states.

This book endeavours to pinpoint the relations between musical, and especially instrumental, practice and the evolving conceptions of pitch systems. It traces the development of ancient melodic notation from reconstructed origins, through various adaptations necessitated by changing musical styles and newly invented instruments, to its final canonical form. It thus emerges how closely ancient harmonic theory depended on the culturally dominant instruments, the lyre and the aulos. These threads are followed down to late antiquity, when details recorded by Ptolemy permit (...) an exceptionally clear view. Dr Hagel discusses the textual and pictorial evidence, introducing mathematical approaches wherever feasible, but also contributes to the interpretation of instruments in the archaeological record and occasionally is able to outline the general features of instruments not directly attested. The book will be indispensable to all those interested in Greek music, technology and performance culture and the general history of musicology. (shrink)

Los descubrimientos de las neurociencias permiten intervenir en el cerebro humano para mejorar su estado o sus capacidades sin indicación médica. Este fenómeno es conocido como “Neuroenhancement” y está sujeto a un amplio debate ético. Como “Neuroenhancement” es un fenómeno evolutivo, el debate de aspectos éticos está necesariamente orientado al futuro y depende de la información sobre el posible desarrollo de la tecnología y sus consecuencias para la sociedad. Sin embargo, hay que establecer límites para la formulación de previsiones especulativas (...) en argumentos éticos y justificaciones políticas. Propongo distinguir argumentos con tres propósitos distintos: la formación de intuiciones éticas, el reflejo sobre el futuro de la sociedad y justificación de normativas y políticas. Para cada uno de ellos necesitamos estándares adecuados. Es tarea de la filosofía política desarrollar un estándar para los argumentos justificadores.: Neuroscientific findings allow interventions in the human brain to improve its function or modify mental states even without medical indication. This procedure, termed as neuroenhancement, is subject to a broad ethical debate. As neuroenhancement is an evolving phenomenon, the debate is necessarily future-oriented and highly dependent on information about future developments. It remains an open question to what degree uncertain forecasting or even speculation should be considered in the ethical debate and policy-making. I propose to distinguish between arguments with three different purposes: intuition-forming, self-reflecting and justifying arguments. Adequate standards are required for all kinds of future-oriented arguments. The development of these standards for justifying arguments is a task for political philosophy. (shrink)

In the article, the author presents attempts by Polish Marxist philosophers to enrich Marxism with ethical issues. The initial absence of ethics in Marxism is associated with the ignorance of tradition related to their own formation. In the author’s opinion, only polemics with the competitive Lviv-Warsaw school forced Polish Marxists to take the issue seriously. That is why Polish Marxist ethics in its mature form was only established in the 1960s, and did not enrich Marxism itself, but rather indirectly contributed (...) to the initiation of socio-political transformations in our country.

Previous studies suggest in line with dual process models that interoceptive skills affect controlled decisions via automatic or implicit processing. The “framing effect” is considered to capture implicit effects of task-irrelevant emotional stimuli on decision-making. We hypothesized that cardiac awareness, as a measure of interoceptive skills, is positively associated with susceptibility to the framing effect. Forty volunteers performed a risky-choice framing task in which the effect of loss versus gain frames on decisions based on identical information was assessed. The results (...) show a positive association between cardiac awareness and the framing effect, accounting for 24% of the variance in the framing effect. These findings demonstrate that good interoceptive skills are linked to poorer performance in risky choices based on ambivalent information when implicit bias is induced by task-irrelevant emotional information. These findings support a dual process perspective on decision-making and suggest that interoceptive skills mediate effects of implicit bias on decisions. (shrink)

This manuscript describes the institutional and clinical considerations that apply to the question of whether to mandate opioid dose reduction in patients who have received opioids long-term. It describes how a calamitous rise in addiction and overdose involving opioids has both led to a clinical recalibration by healthcare providers, and to strong incentives favoring forcible opioid reduction by policy making agencies. Neither the 2016 Guideline issued by the Centers for Disease Control and Prevention nor clinical evidence can justify or promote (...) such policies as safe or effective. (shrink)

This systematic review identified and evaluated instruments measuring patients' perceptions of patient‐centred nursing care. Of 2629 studies reviewed, 12 were eligible for inclusion. Four instruments were reported: The Individualized Care Scale, the Client‐Centred Care Questionnaire, the Oncology patients' Perceptions of the Quality of Nursing Care Scale and the Smoliner scale. These instruments cover themes addressing patient participation and the clinician–patient relationship. Instruments were shown to have satisfactory psychometric properties, although not all were adequately assessed. More research is needed regarding test–retest (...) reliability, convergent and discriminant validity, validity with known groups and structural validity using confirmatory factor analysis. (shrink)

What sort of image does the planet Earth possess at the opening of the 21st century? If in the 1960s, the Whole Earth, the planet as seen from space, became a cold war, proto-environmentalist icon for a fragile ocean planet, in the 2010s, Google Earth, the globe encountered as a manipulable virtual object on our computer screens, has become an index for multiple and socially various interpretations and interventions; its thicket of satellite images, text legends, and street level photographs can (...) all be tagged, commented upon, modified. In this essay, I examine a kindred image-object, Google Ocean, asking what sort of representation of the planetary sea is in the making in our digital days. Stirring up the century-old classification of signs by semiotician Charles Sanders Peirce, I argue that Google Ocean is a mottled mash of icons, indexes, and symbols of the marine and maritime world as well as a simultaneously dystopian and utopian diagram of the sea - though one that floats in a media ecology that tends to occlude its infrastructural history and conditions of possibility.

In this thesis the connection between coherence and reliability is investigated. The question may be phrased as follows: does the fact that a set of testimonies is coherent imply that the witnesses who have reported these testimonies are reliable? The same question may also be expressed in terms of beliefs: does the fact that a set of beliefs is coherent imply that the beliefs were reliably produced? Traditionally, coherence theorists have thought that coherence is connected to truth, but in this (...) dissertation the thesis is that it is rather connected to reliability. The investigation proceeds within a probabilistic framework, the so-called witness scenario, where a number of partially reliable witnesses give independent reports. Hence it is primarily coherent sets of testimonies that are discussed, but coherence of beliefs is taken to function similarly, and thus the results acquired using the witness scenario are, it is argued, relevant for the traditional discussion which mostly concerns coherence of beliefs. Using this scenario a notion of reliability-conduciveness, similar to the much-discussed notion of truth-conducivenes, is formally defined. This definition says, roughly, that a measure of coherence C is reliability-conducive if and only if the more coherent a set of testimonies is, as measured by C, the higher is the probability that a witness who has given one of these testimonies is reliable. In Papers I and II it is tested whether a number of coherence measures proposed in the literature are reliability-conducive in various salient scenarios. It is shown that the only coherence measure that is reliability-conducive in all of those scenarios is the so-called Shogenji measure. This observation is then used to argue that the Shogenji measure is a fruitful explication of the notion of coherence. However, in Paper III it is shown that in the most general scenario neither the Shogenji measure nor any other measure of coherence is reliability-conducive. In Paper IV, the use of coherence reasoning in court is investigated. It is shown that we often use the notion of coherence in judicial reasoning, for example to find out whether certain witnesses are reliable or not. Using the results from Papers I and II, as well as additional formal results that strengthen the connection between coherence and reliability, it is argued that this line of reasoning is valid. Also, it is argued in the introductory chapter that these findings show that coherence is indeed closely connected to reliability, even though it is not generally reliability-conducive, and that this connection is much closer than that between coherence and truth. In Paper V, coherent sets of so-called higher order testimonies are examined, where a higher order testimony is defined as a testimony concerning some other witness’s reliability . Such sets have hitherto not been examined within formal coherence theory. It is shown that coherence must be defined in a non-standard way to account for all our intuitions regarding sets involving higher order testimonies. It is then argued that this shows that in order to correctly estimate the degree of coherence of a set of beliefs, the believer must have a firm grasp of her own reliability; a fact that in turn is taken to be problematic for the coherence theory of justification.

The concept of event is one of the key notions of many theories dealing with causality or agency. In this paper we study different approaches to events that share the basic assumption that events can be analyzed fruitfully in branching-time structures. The terminological framework developed thereby may be helpful for further analyses in the fields of causality and agency and also in those fields of computational semantics, where similar concepts are considered.
