In this paper, we examine the period that immediately followed the invention of the Leiden jar. Historians of science have developed narrations that emphasize the role of grounding during the process of charging the jar. In this respect, this episode shows significant aspects that can be used to characterize science, scientific knowledge production, and the nature of science. From our own experimentation, we learned that grounding was not necessary in order to produce the effect. These experiences inspired us to go (...) back to primary sources. In doing so, we came to a new understanding of the early period after Kleist’s and Musschenbroek’s initial creation of the effect. From our analysis, we conclude that it is not the grounding which was perceived as a major innovation during this early period of the discussion but the concept of an electrical circuit. This understanding was fundamental in characterizing the Leiden jar as a new device challenging the then current knowledge of experimental practices in the field of electricity. (shrink)

Georg Simon Ohm's work in the field of electricity led to what is now considered to be the most fundamental law of electrical circuits, Ohm's Law. Much less known is that only months earlier, Ohm had published another law—one that differed significantly from the now accepted one. The latter entailed a logarithmic relation between the length of the conductor and a parameter that Ohm called “loss of force.” This paper discusses how Ohm came up with an initial law that he (...) felt compelled to correct a few months later. We analyze Ohm's publication as well as his laboratory notes, relating them to our own laboratory experiences while using the replication method to study his work. We also discuss the conceptual background of Ohm's work. We conclude that he was significantly influenced by French studies in the field of electricity, most notably the ones by Charles Augustin Coulomb. (shrink)

Some experiments from the history of physics became so famous that they not only made it into the textbook canon but were transformed into lecture demonstration performances and student laboratory activities in the nineteenth and twentieth centuries. While, at first glance, some of these demonstrations as well as the related instruments do resemble their historical ancestors, a closer examination reveals significant differences both in the instruments themselves and in the practices and meanings associated with them. In this paper, I analyse (...) the relation between the research instruments and the respective teaching demonstrations. In doing so, I particularly distinguish between demonstrations that address the process of the actual experimental procedures, and those that focus on the outcome or results (the product) of the experiment. This distinction will be illustrated in some exemplary case studies from the late nineteenth century and the early twentieth in which both the historical experiment and the related educational devices are analysed. The tension between the historical experiment on the one hand, and the different variants of the teaching version on the other, result in the educational as well as epistemological problems that are discussed in this paper.

This paper discusses essential elements of the philosophical works of Ludwik Fleck and their potential interpretation for the teaching and learning of science. In the early twentieth century, Fleck made substantial contributions to understanding the sociological character of the nature of science and explaining the embedding of science in society. His works have several parallels to the later and very popular work, The Structure of Scientific Revolutions, by Thomas S. Kuhn, although Kuhn only indirectly referred to the influence of Fleck (...) on his own theories. Starting from a short review of the life of Ludwik Fleck, his philosophical work and its connections to Kuhn, this paper elaborates upon and illustrates how his theories can be considered for science education in order to provide learners with a better understanding of the nature of scientific endeavor and the bi-directional science-to-society links.

These proceedings of the International Conference for the History of Science in Science Education (ICHSSE) 2012 offer a snapshot of the work and conversations at an increasingly busy intersection: history of science, museum and science center staff, and science educators.

Many think it is plausible that agents enjoy freedom and responsibility with respect to their actions in virtue of being reasons-responsive. Extant accounts spell out reasons-responsiveness (RR) as a general modal property. The agent is responsive to reasons for and against ϕ-ing, according to this idea, if they ϕ in accordance with the balance of reasons in a suitable proportion of possible situations. This paper argues that freedom and responsibility are not grounded in such modal properties on the basis of (...) a phenomenon I call ‘rational blind spots’. Agents have highly specific local blockages (or openings) that prevent them from seeing or reacting for a particular type of reason. When these blind spots are triggered, agents fail to be responsive to reasons in the sense relevant to freedom and responsibility. Thus, we judge that they are not free and responsible. But bind spots don’t remove the agent’s possession of general modal RR properties. Thus, extant accounts of reasons-responsiveness render the incorrect result that the agents in these cases remain responsible because they remain responsive to reasons in a general sense. (shrink)

ABSTRACT There are two tenets about free agency that have proven difficult to combine: free agency is grounded in an agent’s possession or exercise of their reasons-responsiveness, only actual sequence features can ground free agency. This paper argues that and can only be reconciled if we recognise that their clash is just the particular manifestation of a wider conflict between two approaches to the notion of non-accidentality. According to modalism, p is non-accidentally connected to q iff p modally tracks q. (...) According to explanationism, p is non-accidentally connected to q iff q explains p in the right way. The conflict between these two approaches becomes manifest in Frankfurt-like cases for many notions, in which p and q are intuitively non-accidentally connected even though there is no modal tracking between them. Thus, and can’t be combined because the Frankfurt-cases upon which rests track explanationist intuitions, while the non-accidentality requirement of reasons-responsiveness in is usually spelled out in modalist terms. Hence, the possibility of an actual sequence reasons-responsiveness account depends on finding an explanationist approach to the non-accidentality requirement of reasons-responsiveness. (shrink)

When do two sentences say the same thing, that is, express the same content? We defend two-component (2C) semantics: the view that propositional contents comprise (at least) two irreducibly distinct constituents, (1) truth-conditions, and (2) subject-matter. We contrast 2C with one-component (1C) semantics, focusing on the view that subject-matter is reducible to truth- conditions. We identify exponents of this view and argue in favor of 2C. An appendix proposes a general formal template for propositional 2C semantics.

Friedrich Heer hat seine 1953 zum ersten Mal erschienene, nun seit Jahrzehnten vergriffene "Europäische Geistesgeschichte" trotz ihres Umfangs von über 700 Seiten einen "Essay" genannt. Bedenkt man den eigentlichen Sinn des Wortes "Essay" - Versuch, Wagnis -, dann entspringt diese Bezeichnung nicht falscher Bescheidenheit. Das Werk zieht einen großen Bogen von Auseinandersetzungen im frühen Christentum bis zur Zeit Goethes und skizzenhaft weiter bis in die Mitte des 20. Jahrhunderts - immer bemüht, zugleich die gemeineuropäischen geistigen Entwicklungen und die Eigenart der (...) einzelnen Nationen gerecht zu würdigen. Die Perspektive ist eine katholische, nicht in einem engen kirchlichen Sinn, sondern im Bewusstsein der Bedeutung der Kirche für die Herausbildung dessen, was wir als Europa kennen. "Essay" ist das Buch als Versuch, als Wagnis, große (und manchmal verkannte) Linien der europäischen Geistesgeschichte herauszuarbeiten. Zum "Essay" macht es auch die Leidenschaft, mit der es geschrieben ist. Andererseits ist Friedrich Heers "Europäische Geistesgeschichte" ein wissenschaftliches Werk von hohem Rang, in welches das enzyklopädische Wissen seines Autors eingeflossen ist. So werden hier in durchaus spannender Weise Zusammenhänge hergestellt, die ein überzeugendes Bild von Einheit und Unterschiedlichkeit der geistigen Entwicklung dieses Kontinents entstehen lassen. Mit besonderem Engagement werden alle nicht konformen Strömungen dieser Geistesgeschichte vorgestellt. Die Fülle von Anregungen, die dieses Buch bietet, wird kaum von einem anderen übertroffen. Was immer im Einzelnen zu kritisieren sein mag, was immer neue Detailforschungen ergeben haben - die dauernden Tendenzen der geistigen Entwicklung Europas werden nirgends so klar wie hier. Als Ganzes ist das Bild, das Heer von der geistigen Entwicklung Europas zeichnet, nicht überholt. (shrink)

Berkeley’s likeness principle is the claim that “an idea can be like nothing but an idea”. The likeness principle is intended to undermine representationalism: the view (that Berkeley attributes to thinkers like Descartes and Locke) that all human knowledge is mediated by ideas in the mind which represent material objects. Yet, Berkeley appears to leave the likeness principle unargued for. This has led to several attempts to explain why Berkeley accepts it. In contrast to ‘metaphysical’ and ‘epistemological’ interpretations available in (...) the literature, in this paper I defend a ‘conceptual’ interpretation. I argue that Berkeley accepts the likeness principle on the basis of (i) his commitment to the transparency of ideas, and (ii) his account of resemblance which he sets out in his works on vision. Thus, I provide an explanation for Berkeley’s reasons for accepting the likeness principle which, appropriately, focuses on his views concerning ideas and likeness. (shrink)

Margaret Macdonald was at the institutional heart of analytic philosophy in Britain in the mid-twentieth century. Yet, her views on the nature of philosophical theories diverge quite considerably from those of many of her contemporaries. In this paper, I focus on her 1953 article ‘Linguistic Philosophy and Perception’, a provocative paper in which Macdonald argues that the value of philosophical theories is more akin to that of poetry or art than science or mathematics. I do so for two reasons. First, (...) because it reveals just how far Macdonald’s meta- philosophical views diverged from those of many of her contemporaries. Second, because the discussion in LPP pre-empts recent literature on the nature of philosophical inquiry and the efficacy of philosophical arguments. Indeed, Macdonald’s paper is just as likely to provoke discussion today as it was in the 1950s. (shrink)

A fun introduction in comics to deep thinking and the history of philosophy -- Back cover.

Current literature suggests that corporate social responsibility (CSR) can affect consumers’ attitudes towards an organization and is regarded as a driver for reputation-building and fostering sustained consumer patronage. Although prior research has addressed the direct influence of CSR on consumer responses, this research examined the mediating influence of consumer’s perceived organizational motives within an NGO setting. Given the heightened public attention surrounding the 2008 Beijing Olympic Games, data were collected from consumers of the Games to assess their perceptions of the (...) International Olympic Committee’s (IOC) socially responsible initiatives. We hypothesized that consumers of the Games were likely to cognitively elaborate on CSR messages by way of three specific attribution effects derived from the literature. The results show that, contingent on CSR awareness, consumers responded positively to social efforts judged to be values-driven and stakeholder-driven; and a negative response was seen for efforts judged to be strategic. These attribution effects influenced various types of patronage and perceived organizational reputation. (shrink)

This paper provides a philosophical evaluation of the concept of handedness prevalent but largely unspoken in the scientific literature. This literature defines handedness as the preference or ability to use one hand rather than the other across a range of common activities. Using the philosophical discipline of phenomenology, I articulate and critique this conceptualization of handedness. Phenomenology shows defining a concept of handedness by focusing on hand use leads to a right hand biased concept. I argue further that a phenomenological (...) model based in spatial orientation rather than hand use provides a more inclusive concept of handedness. (shrink)

According to a popular idea, freedom is grounded in orthonomy – the ability to be responsive to normative demands. But how exactly must an agent’s action relate to their reasons in order for this orthonomous relationship to hold? In this paper, I propose a novel explanationist answer to this question. I argue that extant answers – causalism and modalism about orthonomy – fail because they fail to account for the fact that intuitions about freedom and orthonomy track facts about explanation. (...) And these facts cannot be reduced to either causal or modal facts. Instead, I propose that we should understand freedom as grounded in special accidentality-dispersing explanations in terms of normative reasons. The resultant view is to be understood as following a Frankfurtian intuition: only factors that explain action can be relevant to whether the action is free. (shrink)

Since its original publication in 1975, this groundbreaking work has awakened millions of people to the existence of "speciesism"—our systematic disregard of nonhuman animals—inspiring a worldwide movement to transform our attitudes to animals and eliminate the cruelty we inflict on them. In Animal Liberation, author Peter Singer exposes the chilling realities of today’s "factory farms" and product-testing procedures—destroying the spurious justifications behind them, and offering alternatives to what has become a profound environmental and social as well as moral issue. (...) An important and persuasive appeal to conscience, fairness, decency, and justice, it is essential reading for the supporter and the skeptic alike. (shrink)

It is argued that causal understanding originates in experiences of acting on objects. Such experiences have consistent features that can be used as clues to causal identification and judgment. These are singular clues, meaning that they can be detected in single instances. A catalog of 14 singular clues is proposed. The clues function as heuristics for generating causal judgments under uncertainty and are a pervasive source of bias in causal judgment. More sophisticated clues such as mechanism clues and repeated interventions (...) are derived from the 14. Research on the use of empirical information and conditional probabilities to identify causes has used scenarios in which several of the clues are present, and the use of empirical association information for causal judgment depends on the presence of singular clues. It is the singular clues and their origin that are basic to causal understanding, not multiple instance clues such as empirical association, contingency, and conditional probabilities. (shrink)

In this important new book in the IPPP series, a group of leading thinkers in psychiatry, psychology, and philosophy offer alternative perspectives that address both the scientific and clinical aspects of psychiatric validation, emphasizing throughout their philosophical and historical considerations.

Prospect Theory: For Risk and Ambiguity, provides a comprehensive and accessible textbook treatment of the way decisions are made both when we have the statistical probabilities associated with uncertain future events and when we lack them. The book presents models, primarily prospect theory, that are both tractable and psychologically realistic. A method of presentation is chosen that makes the empirical meaning of each theoretical model completely transparent. Prospect theory has many applications in a wide variety of disciplines. The material in (...) the book has been carefully organized to allow readers to select pathways through the book relevant to their own interests. With numerous exercises and worked examples, the book is ideally suited to the needs of students taking courses in decision theory in economics, mathematics, finance, psychology, management science, health, computer science, Bayesian statistics, and engineering.

William Molyneux was born in Dublin, studied in Trinity College Dublin, and was a founding member of the Dublin Philosophical Society (DPS), Ireland’s counterpart to the Royal Society in London. He was a central figure in the Irish intellectual milieu during the Early Modern period and – along with George Berkeley and Edmund Burke – is one of the best-known thinkers to have come out of that context and out of Irish thought more generally. In 1688, when Molyneux wrote the (...) letter to Locke in which he posed the now famous question about a man born blind made to see, he was an active member of the DPS and was on familiar terms with several other key figures in Irish philosophy at the time. For the most part, Irish thinkers in the seventeenth and eighteenth centuries answered “no” to Molyneux’s question of whether a blind man made to see could distinguish, by sight alone, between a cube and a sphere.
