As interpretações referentes ao relacionamento entre Blaise Pascal e Renné Descartes costumam situar-se entre dois extremos. Algumas vezes, o autor dos Pensamentos é interpretado como uma espécie de cartesiano indeciso, incapaz de separar o seu discurso religioso das investigações científicas e filosóficas. Outras vezes, Pascal é estereotipado como uma espécie de anti-cartesiano empedernido, um apologista cuja fé não pode evitar o racionalismo. O presente busca evitar estas duas compreensões, tentando encontrar um Pascal que foi cartesiano em certa medida, mas, ao (...) mesmo tempo, crítico de Descartes, sem que, contudo, tal crítica justifique a acusação de irracionalismo.

The social epistemology of science would benefit from paying more attention to the nature of argumentative exchanges. Argumentation is not only a cognitive activity but a collaborative social activity whose functioning needs to be understood from a psychological and communicative perspective. Thus far, social and organizational psychology has been used to discuss how social diversity affects group deliberation by changing the mindset of the participants. Argumentative exchanges have comparable effects, but they depend on cognitive diversity and emerge through critical interaction. (...) An example of a cognitive psychological theory is discussed that explains how mutual reasoning affects how we think, make decisions, and solve problems, as well as how cognitive biases may facilitate an efficient division of cognitive labor. These observations are compared with the existing results in the social epistemology of science. Moreover, I explicate the conceptual differences between the distributed and social processing of information. While argumentative exchanges belong to the latter domain, most existing simulations model distributed processing, which may compromise their real-world relevance and proper conceptual interpretation. However, I aim not to criticize the existing simulation methods but to promote an approach from the cognitive psychology of reasoning that complements the current use of organizational psychology and computer simulations by investigating a different set of mechanisms relating to similar phenomena of interest in the social epistemology of science.

While most business ethics texts focus exclusively on individual decision making--what should an individual do--this resource presents the whole business ethics story. Highly realistic, readable, and down-to-earth, it moves from the individual to the managerial to the organizational level, focusing on business ethics in an organizational context to promote an understanding of complex influences on behavior. The new Fifth Edition is the perfect text for students entering the workplace, those seeking to become professionals in training, communications, compliance, in addition to (...) chief ethics officers, corporate counsel, heads of human resources, and senior executives.

Pitkälti samalla tavalla kuin opimme meille tärkeitä ympäristön säännönmukaisuuksia ja monimutkaisia taitoja, opimme myös sosiaalisia rutiineja käytäntöjä. Käsitteellinen ymmärtäminen pohjautuu kykyyn käyttää ympäristömme säännönmukaisuuksia koskevaa tietoa päämääriemme suhteen mielekkäillä tavoilla, ja tämä koskee myös sosiaalista tietoa sanojen ja symbolien tarkoituksenmukaisesta käyttämisestä. Näin ollen käsitteitä, ymmärtämistä ja järkeilyä tulisi psykologisesti tarkastella ensisijaisesti taitamiseen eikä tietämiseen liittyvänä ilmiönä.

The ArgumentWe present a number of findings concerning Galileo's major discoveries which question both the methods and the results of dating his achievements by common historiographic criteria. The dating of Galileo's discoveries is, however, not our primary concern. This paper is intended to contribute to a critical reexamination of the notion of discovery from the point of view of historical epistemology. We claim that the puzzling course of Galileo's discoveries is not an exceptional comedy of errors but rather illustrates the (...) normal way in which scientific progress is achieved. We argue that scientific knowledge generally develops not as a sequence of independent discoveries accumulating to a new body of knowledge but rather as a network of interdependent activities which only as a whole makes the individual steps understandable as meaningful “discoveries.”.

The history of science can be better understood against the background of a history of knowledge comprising not only theoretical but also intuitive and practical knowledge. This widening of scope necessitates a more concise definition of the concept of knowledge, relating its cognitive to its material and social dimensions. The history of knowledge comprises the history of institutions in which knowledge is produced and transmitted. This is an essential but hitherto neglected aspect of cultural evolution. Taking this aspect into account (...) one is led to the concept of extended evolution, which integrates the perspectives of niche construction and complex regulative networks. The paper illustrates this concept using four examples: the emergence of language, the Neolithic revolution, the invention of writing and the origin of mechanics. (shrink)

A two stage model was developed and tested to explain how ethical leadership relates to followers’ ethical judgment in an organizational context. Drawing on social learning theory, ethical leadership was hypothesized to promote followers’ self-leadership focused on ethics. It was found that followers’ perceived accountability fully accounts for this relationship. In stage two, the relationship between self-leadership focused on ethics and moral judgment in a dual decision-making system was described and tested. Self-leadership focused on ethics was only related to moral (...) judgment when followers use active judgment as opposed to their intuition. This provides support that a deliberate application of self-leadership focused on ethics leads to higher moral judgment. Theoretical and practical implications as well as future research opportunities are discussed. (shrink)

The history of the theory of general relativity presents unique features. After its discovery, the theory was immediately confirmed and rapidly changed established notions of space and time. The further implications of general relativity, however, remained largely unexplored until the mid 1950s, when it came into focus as a physical theory and gradually returned to the mainstream of physics. This essay presents a historiographical framework for assessing the history of general relativity by taking into account in an integrated narrative intellectual (...) developments, epistemological problems, and technological advances; the characteristics of post–World War II and Cold War science; and newly emerging institutional settings. It argues that such a framework can help us understand this renaissance of general relativity as a result of two main factors: the recognition of the untapped potential of general relativity and an explicit effort at community building, which allowed this formerly disparate and dispersed field to benefit from the postwar changes in the scientific landscape.

We present Dynamic Epistemic Temporal Logic, a framework for reasoning about operations on multi-agent Kripke models that contain a designated temporal relation. These operations are natural extensions of the well-known “action models” from Dynamic Epistemic Logic. Our “temporal action models” may be used to define a number of informational actions that can modify the “objective” temporal structure of a model along with the agents’ basic and higher-order knowledge and beliefs about this structure, including their beliefs about the time. In essence, (...) this approach provides one way to extend the domain of action model-style operations from atemporal Kripke models to temporal Kripke models in a manner that allows actions to control the flow of time. We present a number of examples to illustrate the subtleties involved in interpreting the effects of our extended action models on temporal Kripke models. We also study preservation of important epistemic-temporal properties of temporal Kripke models under temporal action model-induced operations, provide complete axiomatizations for two theories of temporal action models, and connect our approach with previous work on time in DEL.

We present a complete, decidable logic for reasoning about a notion of completely trustworthy evidence and its relations to justifiable belief and knowledge, as well as to their explicit justifications. This logic makes use of a number of evidence-related notions such as availability, admissibility, and “goodness” of a piece of evidence, and is based on an innovative modification of the Fitting semantics for Artemovʼs Justification Logic designed to preempt Gettier-type counterexamples. We combine this with ideas from belief revision and awareness (...) logics to provide an account for explicitly justified knowledge based on conclusive evidence that addresses the problem of omniscience.

The articles collected in this volume have their origin in an international workshop dedicated to “Experience and Knowledge Structures in Arabic and Latin Sciences.” Specialists from Great Britain, France, Denmark, Spain, Morocco, the United States, and Germany gathered in Berlin in 1996 in the context of an interdisciplinary research project on the history of mechanical thinking at the Max Planck Institute for the History of Science. The workshop initiated a process of discussion focused on problems of the intercultural transmission and (...) transformation of knowledge. The present double issue is an outcome of this ongoing discussion. (shrink)

The ArgumentIn this paper I present and argue for a model of conceptual development in science and apply it to the transition from classical to modern physics associated with Einstein. The model claims a continuous and rational transition between incompatible subsequent conceptual systems in mathematical science and explains its mechanism. The model was developed in a study of the transition from preclassical to classical mechanics. I argue for a strong structural analogy between the transition from preclassical to classical mechanics on (...) the one hand and from classical to modern physics on the other. The first transition is briefly sketched here by reference to Galileo and his disciples; in the second transition Planck and Lorentz on the one hand and Einstein on the other play the respective roles.A detailed and documented reconstruction of the transition from preclassical to classical mechanics on the basis of this model has already been published and is only briefly referred to in the paper. The transition from classical to modern physics is portrayed here much more extensively—though of course merely in broad brush strokes. Einstein–s role in this transition is reconstructed in the light of a conceptualization of his scientific knowledge as an active structure of thought, shaped by his intellectual experience. In this way, the development of his individual thinking is shown to be part of the overall process of conceptual transformation from classical to modern physics. The reconstruction sketched in this paper is to be considered as a proposal to be substantiated, reformed, and improved by future detailed studies. (shrink)

Jürgen Renn examines the role of knowledge in global transformations going back to the dawn of civilization while providing vital perspectives on the complex challenges confronting us today in the Anthropocene--this new geological epoch shaped by humankind. Renn reframes the history of science and technology within a much broader history of knowledge, analyzing key episodes such as the evolution of writing, the emergence of science in the ancient world, the Scientific Revolution of early modernity, the globalization of knowledge, (...) industrialization, and the profound transformations wrought by modern science. He investigates the evolution of knowledge using an array of disciplines and methods, from cognitive science and experimental psychology to earth science and evolutionary biology. The result is an entirely new framework for understanding structural changes in systems of knowledge--and a bold new approach to the history and philosophy of science. (shrink)

We present Arrow Update Logic, a theory of epistemic access elimination that can be used to reason about multi-agent belief change. While the belief-changing of Arrow Update Logic can be transformed into equivalent belief-changing from the popular Dynamic Epistemic Logic approach, we prove that arrow updates are sometimes exponentially more succinct than action models. Further, since many examples of belief change are naturally thought of from Arrow Update Logicrelativized” common knowledge familiar from the Dynamic Epistemic Logic literature.

The year 1905 has been called Einstein's annus mirabilis in virtue of three ground-breaking works completed over the span of a few months --- the light quantum paper (Einstein, 1905a), the Brownian motion paper (Einstein, 1905c), and the paper on the electrodynamics of moving bodies introducing the special theory of relativity (Einstein, 1905d). There are prima facie reasons for thinking that the origins of these papers cannot be understood in isolation from one another. Due to space limitations, we concentrate primarily (...) on the light quantum paper, since, in key respects, it marks the turning point for the annus mirabilis. The task is to probe, not just how the idea of the light quantum might have occurred to Einstein, but, more importantly, what convinced him that the idea was not just a quixotic hypothesis, but an unavoidable and demonstrable feature of radiation. The crucial development, we suggest, arose from comparing the energy fluctuations that following rigorously from the Stefan-Boltmann law, as well as from Wien's distribution formula for blackbody radiation, with what it is reasonable to expect from Maxwell's electromagnetic theory of light. A special case of this is addressed in (Einstein, 1904). The outcome for the general case leads naturally to the central theoretical argument of the light quantum paper, the expectation of Brownian-like motion, and several of the key results for the electrodynamics of moving bodies.

Is knowledge definable as justified true belief? We argue that one can legitimately answer positively or negatively, depending on whether or not one’s true belief is justified by what we call adequate reasons. To facilitate our argument we introduce a simple propositional logic of reason-based belief, and give an axiomatic characterization of the notion of adequacy for reasons. We show that this logic is sufficiently flexible to accommodate various useful features, including quantification over reasons. We use our framework to contrast (...) two notions of JTB: one internalist, the other externalist. We argue that Gettier cases essentially challenge the internalist notion but not the externalist one. Our approach commits us to a form of infallibilism about knowledge, but it also leaves us with a puzzle, namely whether knowledge involves the possession of only adequate reasons, or leaves room for some inadequate reasons. We favor the latter position, which reflects a milder and more realistic version of infallibilism. (shrink)

In his theory of communication Schutz exhibits a significant tension between two fundamental perspectives, phenomenology and pragmatism, and in the long run he fails to reconcile the contradictory implications these perspectives have with regard to his model of interaction.The main problem seems to be the notion of sense-constitution. Schutz develops two distinguishable accounts of constitution: an egological one and a model based on the phenomenon of direct interaction of empirical subjects. Two key concepts are related to these different modes of (...) constitution: the model of appresentation with regard to language, symbols and signs, and the model of synchronisation as triangulation of streams of consciousness and outward action sequences. They are analyzed as significant for two different methods and two different theories of communication. I propose some reasons for Schutz's insistence on a phenomenological account of the ego and the constitution of sense, and offer a brief sketch of an alternative strategy that is implicit in Schutz's theory.

Dynamic Epistemic Logic (DEL) is the study of how to reason about knowledge, belief, and communication. This paper studies the relative expressivity of certain fragments of the DEL language for public and private communication. It is shown that the language of public communication with common knowledge and the language of private communication with common knowledge are expressively incomparable for the class of all pointed Kripke models, which provides a formal proof that public and private communication are fundamentally different in the (...) presence of common knowledge. It is also shown that single-recipient private communication does not add expressive power to the language of modal logic with common knowledge for any class of transitive pointed Kripke models. The latter result provides a sense in which positive introspection—believing our own beliefs—induces a kind of self-dialog. (shrink)

In chapter 3 of Wild Animal Ethics Johannsen argues for a collective obligation based on beneficence to intervene in nature in order to reduce the suffering of wild animals. In the same chapter he claims that the non-identity problem is merely a “theoretical puzzle” which doesn’t affect our reasons for intervention. In this paper I argue that the non-identity problem affects both the strength and the nature of our reasons to intervene. By intervening in nature on a large scale we (...) change which animals come into existence. In doing so, we enable harmful animals to inflict harms on other animals, and we put other animals in harm’s way. The harms that these animals will inflict and endure are foreseeable. Furthermore, since non-human animals aren’t moral agents, harmful animals cannot be morally responsible for their harmful actions. I argue therefore that by causing animals to exist, knowing that they will inflict and suffer harms, we become morally responsible for those harms. By engaging in identity-affecting actions then we take on secondary moral duties towards the animals we have thereby caused to exist, and these secondary moral duties may be extremely demanding, even more so than the initial costs of intervention. Finally, these duties are duties of justice rather than duties of beneficence, and as such are more stringent than purely beneficence-based moral reasons. Furthermore, this conclusion flows naturally from several plausible principles which Johannsen explicitly endorses. (shrink)

Complex modern societies require new ways of political conflict solution, especially concerning environmental conflicts. We distinguish six forms of conflict solution, including those of mediated bargaining and cooperative discourse. If one opts for cooperative discourse, further orientation according to criteria such as fairness, competence, legitimation and efficiency seems to be important. Three procedural steps within cooperative discourse-i.e. establishing relevant value attitudes, expert-hearings, evaluation of options by citizen panels-are sketched and critically discussed, making use of experience from recent discoursive siting panels (...) in Switzerland and Southern Germany. With the exception of a legitimatory deficiency (which may be improved) cooperative discourse and citizen participation in environmental decision-making turn out to be most promising. (shrink)

In 1877 Louis Paul Cailletet in France and Raoul Pictet in Switzerland liquefied oxygen in the form of a mist. The liquefaction of the first of the so-called permanent gases heralded the birth of low-temperature research and is often described in the literature as having started a ‘race’ for attaining progressively lower temperatures. In fact, between 1877 and 1908, when helium, the last of the permanent gases, was liquefied, there were many priority disputes—something quite characteristic of the emergence of a (...) new research field. This paper examines Cailletet’s path to the liquefaction of oxygen, as well as a debate between him and the Polish physicist Zygmunt Wróblewski over the latter’s contribution to the liquefaction of gases.

Galileo’s last publication, his Discorsi e dimostrazioni matematiche intorno a due nuove scienze attenenti alla mecanica & i movimenti locali (1638), is widely considered to be one of the most influential contributions of early modern science to the emergence of classical physics. As the title of Galileo’s book indicates, he himself claimed to have established “two new sciences,” including a new science of motion which, from the perspective of classical physics, indeed turned the Aristotelean theory of motion, which had prevailed (...) for hundreds of years, into an obscure medieval relic.
