Les analyses des parcours de vie s’intéressent surtout au repérage des régularités du cycle de vie ou, tout au plus, aux écarts aux modèles types, en termes de retard des événements ou d’allongement des transitions sur les calendriers scolaires, professionnels, résidentiels ou familiaux. Les études empiriques suggèrent pourtant la présence de dynamiques non linéaires évoquant la possibilité que les parcours comportent des « bifurcations » où tout peut être remis en question, pouvant entraîner des changements durables de situation. Ce phénomène (...) est plus souvent interprété en référence à la capacité des individus de faire leurs propres choix qu’en fonction de l’influence possible des cadres institutionnels. L’étude de parcours scolaires et professionnels de jeunes Québécois dans les années 1990 constitue la base de cette réflexion sur la place des bifurcations dans les parcours de vie qui met l’accent sur le rôle des dispositifs institutionnels dans la création d’une flexibilité des structures, sur les phénomènes d’appropriation par les individus des opportunités offertes par cette flexibilité et sur le mouvement des réversibilités et irréversibilités construites à travers ce processus. L’analyse suggère que les individus peuvent s’engager dans des actions en évaluant les possibilités offertes par les institutions qui encadrent la vie sociale, qu’ils sont capables de percevoir les irréversibilités associées aux choix offerts et ainsi, de les prévenir, les exploiter ou s’y adapter. La croissance du nombre de personnes adoptant les mêmes comportements dans une situation donnée accroît ainsi la possibilité que ce choix se transforme en une convention sociale et que les bifurcations s’institutionnalisent.Life course analyses are mainly interested in identifying regularities in the life cycle or, at most, in deviations from typical patterns in terms of a postponing of events or of transitions within educational, career, residential or family trajectories. However, empirical studies point to the existence of non-linear dynamics and suggest the possibility that life paths may also include « bifurcations », where everything is placed in question, and that may lead to lasting changes in situations. This phenomenon is more often interpreted in reference to the individual’s capacity to make personal choices rather than in terms of the potential influence of institutional frameworks. This study is based on an analysis of the educational and career trajectories of Québec youth during the 1990s : it looks at the role of bifurcations in the life course, in emphasizing how institutional arrangements may help to create a flexibility of structures, and explores the phenomena of individuals seizing the opportunities offered by this flexibility. The study suggests that individuals may undertake actions after evaluating the opportunities presented by social institutions, and that they are able to grasp the irreversibility of certain choices and anticipate them, use them to their advantage or adjust their actions accordingly. An increase in the number of persons adopting the same behaviours in a given situation thus also increases the possibility that such a choice may evolve into a social convention and that these bifurcations may become institutionalized.

A leading idea of cultural evolutionary theory is that for human cultures to undergo evolutionary change, cultural transmission must generally serve as a high-fidelity copying process. In analogy to genetic inheritance, the high fidelity of human cultural transmission would act as a safeguard against the transformation and loss of cultural information, thus ensuring both the stability and longevity of cultural traditions. Cultural fidelity would also serve as the key difference-maker between human cumulative cultures and non-human non-cumulative traditions, explaining why only (...) us humans, with our uniquely high-fidelity transmission capabilities, are capable of evolving and sustaining complex traditions. But what does it mean for cultural transmission to be more or less faithful? This article has two objectives. The first is to clarify the meaning and uses of the concept of cultural fidelity and to evaluate their explanatory import. I argue that cultural evolutionists use several fidelity concepts (episodic, propensity, and generalized fidelity), concepts that I will define and clarify. The second objective is to challenge the explanatory significance of a general notion of fidelity (generalized fidelity) as being both explanatorily meaningful and operationalizable. I conclude that if fidelity is to serve as an explanation of the key differences between human cumulative cultures and non-human non-cumulative traditions, then the concept will have to be redesigned and rely on different assumptions. 1Introduction 2Generalized Fidelity 2.1The need for an explanatory concept of fidelity 2.2Three conditions for a general notion of cultural fidelity 3Episodic Fidelity 3.1Measuring episodic fidelity 3.2The relevance problem 3.3Explanatory pluralism 3.4The incommensurability of fidelity metrics 4Propensity Fidelity 5Fidelity as an Explanatory Concept 5.1Explaining cultural stability 5.2Explaining human distinctiveness 6Conclusion.

High-fidelity cultural transmission, rather than brute intelligence, is the secret of our species’ success, or so many cultural evolutionists claim. It has been selected because it ensures the spread, stability and longevity of beneficial cultural traditions, and it supports cumulative cultural change. To play these roles, however, fidelity must be a causally-efficient property of cultural transmission. This is where the grain problem comes in and challenges the explanatory potency of fidelity. Assessing the degree of fidelity of any episode or mechanism (...) of cultural transmission always depends upon an investigator’s choice of grain of description at which cultural traditions are being studied. The fidelity of cultural transmission then appears to be relative to the granularity at which one approaches cultural variation, and since there is a multiplicity of grains of description by which the same tradition can be studied, there results a multiplicity of measures of fidelity for a same event or mechanism of cultural transmission. If this is correct, because fidelity is always relative to the grain of description dictated by the local and specific research interests of the investigator, then there seems to be no fact of the matter as to whether cultural transmission is faithful or not, independently from a researcher’s framework of analysis. The aims of this paper are to offer a conceptual clarification of the grain problem in cultural evolution, to assess its causes, to unpack its epistemological implications, and to examine its reach and consequences for a science of cultural evolution.

For a population to undergo evolution by natural selection, it is assumed that the constituents of the population form parent-offspring lineages, that is, that they must reproduce. I challenge this assumption by dividing the notion of reproduction into two subprocesses, that is, multiplication and inheritance, that produce parent-offspring lineages between the parts of a population, and I show that their population-level roles, generation and memory, respectively, can be effected by processes that do not rely on such local-level lineages. I further (...) argue that these two population-level processes, not local parent-offspring lineages, are necessary conditions for a population to undergo Darwinian evolution. (shrink)

The use of physical models of molecular structures as research tools has been central to the development of biochemistry and molecular biology. Intriguingly, it has received little attention from scholars of science. In this paper, I argue that these physical models are not mere three-dimensional representations but that they are in fact very special research tools: they are cognitive augmentations. Despite the fact that they are external props, these models serve as cognitive tools that augment and extend the modeler’s cognitive (...) capacities and performance in molecular modeling tasks. This cognitive enhancement is obtained because of the way the modeler interacts with these models, the models’ materiality contributing to the solving of the molecule’s structure. Furthermore, I argue that these material models and their component parts were designed, built and used specifically to serve as cognitive facilitators and cognitive augmentations. (shrink)

The cumulative open-endedness of human cultures represents a major break with the social traditions of nonhuman species. As traditions are altered and the modifications retained along the cultural lineage, human populations are capable of producing complex traits that no individual could have figured out on its own. For cultures to produce increasingly complex traditions, improvements and modifications must be kept for the next generations to build upon. High-fidelity transmission would thus act as a ratchet, retaining modifications and allowing the historical (...) buildup of complex traditions. Mechanisms acting against slippage are important, of course, but cultures also need to move forward for the ratchet to retain anything important. In this article, I argue that studies of modification-generating processes and the many ways they shape cumulative culture have been overlooked. Key to a better understanding of cultural modification processes is taking seriously that cultural traditions consist of complex, hierarchically structured recipes. Taking such structures seriously and assessing the different ways they can vary in cultural design space, a novel picture for the onset of cumulative cultural evolution emerges. I argue that a possible impediment for cumulative culture in nonhuman animals may in fact reside not so much in the fidelity of their social transmission but rather in the constraints, internal and external, on their capacity to modify complex, hierarchically structured cultural recipes. (shrink)

Social transmission is at the core of cultural evolutionary theory. It occurs when a demonstrator uses mental representations to produce some public displays which in turn allow a learner to acquire similar mental representations. Although cultural evolutionists do not dispute this view of social transmission, they typically abstract away from the multistep nature of the process when they speak of cultural variants at large, thereby referring both to variation and evolutionary change in mental representations as well as in their corresponding (...) public displays. This conflation suggests that differentiating each step of the transmission process is redundant. In this paper, I examine different forms of interplay between the multistep nature of social transmission and the metric spaces used by cultural evolutionists to measure cultural variation and to model cultural change. I offer a conceptual analysis of what assumptions seem to be at work when cultural evolutionists conflate the complex causal sequence of social transmission as a single space of variation in which populations evolve. To this aim, I use the framework of variation spaces, a formal framework commonly used in evolutionary biology, and I develop two theoretical concepts, ‘technique’ and ‘technical space’, for addressing cases where the complexity of social transmission defies the handy assumption of a single variation space for cultural change. (shrink)

Cultural evolutionists typically emphasize the informational aspect of social transmission, that of the learning, stabilizing, and transformation of mental representations along cultural lineages. Social transmission also depends on the production of public displays such as utterances, behaviors, and artifacts, as these displays are what social learners learn from. However, the generative processes involved in the production of public displays are usually abstracted away in both theoretical assessments and formal models. The aim of this paper is to complement the informational view (...) with a generative dimension, emphasizing how the production of public displays both enable and constrain the production of modular cultural recipes through the process of innovation by recombination. In order to avoid a circular understanding of cultural recombination and cultural modularity, we need to take seriously the nature and structure of the generative processes involved in the maintenance of cultural traditions. A preliminary analysis of what recombination and modularity consist of is offered. It is shown how the study of recombination and modularity depends on a finer understanding of the generative processes involved in the production phase of social transmission. Finally, it is argued that the recombination process depends on the inventive production of an interface between modules and the complex recipes in which they figure, and that such interfaces are the direct result of the generative processes involved in the production of these recipes. The analysis is supported by the case study of the transition from the Oldowan to the Early Acheulean flake detachment techniques. (shrink)

This paper aims at extending the notion of thing knowledge put forth by Davis Baird. His Thing Knowledge (Baird 2004) proposes that scientific instruments constitute scientific knowledge and that to conceive scientific instruments as such brings about a new and better understanding of scientific development. By insisting on what “truth does for us,” Baird shows that the functional properties of truth are shared by the common scientific instrument. The traditional definition of knowledge as justified true belief would only apply to (...) scientific instrumentation if we were to reject the subjective (and intentional) aspect of it, viz. belief. In consequence, Baird insists that scientific instruments can be seen only as a kind of objective knowledge, that is knowledge maintained by the scientific community but not individually by a given scientist. In this paper, I will argue for a conception of subjective thing knowledge according to which some scientific instruments (especially material models) can be understood as justified true beliefs. By combining Davis Baird’s thing knowledge and Clark and Chalmers’ hypothesis of extended cognition, I will show that it is possible to derive an analysis of material models as cognitive augmentation of the scientist's mind, and that such scientific instruments are to be understood as a material form of subjective knowledge, i.e. as external-to-the-brain justified true beliefs.

This chapter argues that recent attempts to make sense of the delusion of thought insertion in terms of a distinction between two notions of thought ownership have been unsuccessful. It also proposes an alternative account, in which the delusion is to be interpreted in the light of its prehistory.

There is a plurality of theoretical approaches, methodological tools, and explanatory strategies in the social sciences. Different fields rely on different methods and explanatory tools even when they study the very same phenomena. We illustrate this plurality of the social sciences with the studies of crowds. We show how three different takes on crowd phenomena—psychology, rational choice theory, and network theory—can complement one another. We conclude that social scientists are better described as researchers endowed with explanatory toolkits than specialists of (...) some specific social domain. Social scientists’ toolkits are adapted for identifying and specifying the role of specific causal factors among the multiple factors that produce social phenomena. These factors can be, in a nonexclusive way, economic incentives, psychological processes, the ecology, or aspects of the social and cultural environment. The plurality of methods and theories in the social sciences flies in the face of the project to unify the sciences associated with the positivists of the nineteenth and twentieth centuries. Yet, the compatibility and consilience of theories and practices still have epistemic value: they enable the development of more powerful and robust theories and they allow the advent of interdisciplinary studies. We present the integrative stance as the will to improve compatibility and consilience across fields, yet recognize that the plurality of causes of social phenomena invite a diversity of methodological and theoretical tools. We conclude by characterizing naturalism as an integrative stance applied to fields that belong to the social science and to the natural sciences. (shrink)

The question of whether cultural transmission is faithful has attracted significant debate over the last 30 years. The degree of fidelity with which an object is transmitted depends on 1) the features chosen to be relevant, and 2) the quantity of details given about those features. Once these choices have been made, an object is described at a particular grain. In the absence of conventions between different researchers and across different fields about which grain to use, transmission fidelity cannot be (...) evaluated because it is relative to the choice of grain. In biology, because a genotype-to-phenotype mapping exists and transmission occurs from genotype to genotype, a privileged grain of description exists that circumvents this ‘grain problem.’ In contrast, in cultural evolution, the genotype–phenotype distinction cannot be drawn, rendering claims about fidelity dependent upon researchers’ choices. Thus, due to a lack of unified conventions, claims about fidelity transmission are difficult to evaluate. (shrink)

Si l’on connaît aujourd’hui le dialogue fructueux que Paul Ricœur a noué avec les penseurs structuralistes, on ignore largement son positionnement face à la mouvance poststructuraliste. Faut-il opposer la philosophie de Ricœur au poststructuralisme à la française ou au contraire doit-on montrer qu’elle en est une variante singulière? C’est la seconde option qui est ici défendue. Certes, le poststructuralisme ne doit pas être considéré comme une école de pensée mais comme une reconstruction qui relève de l’histoire de la philosophie. Dans (...) la mesure où les horizons de dépassement du structuralisme ont été posés de manière chaque fois particulière, il est préférable de parler de poststructuralismes au pluriel. C’est la raison pour laquelle J. Michel propose des confrontations dyadiques entre Ricœur et certains de ses contemporains que l’on regroupe habituellement dans cette mouvance. (shrink)

Sartre's reading of Harald Höffding's works was instrumental in his critical reception of Spinoza. One may find traces of Höffding's critical monism in Sartre's Being and Nothingness . Höffding had formulated his critical monism in order to remedy what he perceived to be problems in Spinoza's view. Sartre's critique of Spinoza aligns with that of Höffding. Moreover, Höffding's influence on Sartre goes well beyond the reception of Spinoza. Indeed, the young Sartre's interest in Bergson, psychology and questions relative to the (...) totality of Being could have followed from his reading of Höffding. In fact, the way in which Höffding tackles questions about the soul, the world, and God illuminates the timid proposals offered by Sartre in the conclusion of Being and Nothingness. Thus, understanding Höffding French Cet article démontrera que la réception critique de Spinoza par Sartre est influencée par sa lecture des oeuvres de Harald Höffding. Une lecture attentive permet d'identifier des traces du monisme critique de celui-ci dans L'être et le néant . Ce monisme critique avait été formulé afin de pallier aux problèmes perçus par Höffding chez Spinoza. Or, cette même critique se retrouve chez Sartre. De plus, cet article fera aussi la démonstration que l'influence de Höffding sur Sartre va au-delà de la réception de Spinoza. En effet, l'intérêt du jeune Sartre pour Bergson, la psychologie et les questions relatives à la totalité de l'Être pourraient être le résultat de sa lecture de Höffding. En fait, la manière dont Höffding traite des questions de l'âme, du monde et de Dieu éclairent les timides propositions métaphysiques offertes par Sartre en conclusion de L'être et le néant . Par conséquent, bien comprendre Höffding permet de mieux comprendre Sartre. (shrink)

Noam Chomsky and Frances Egan argue that David Marr’s computational theory of vision is not intentional, claiming that the formal scientific theory does not include description of visual content. They also argue that the theory is internalist in the sense of not describing things physically external to the perceiver. They argue that these claims hold for computational theories of vision in general. Beyond theories of vision, they argue that representational content does not figure as a topic within formal computational theories (...) in cognitive science. I demonstrate that Chomsky’s and Egan’s claims about Marr’s theory are false. Marr’s computational theory contains a mathematical theory of visual content, based on empirical psychophysical evidence. It also contains mathematical descriptions of distal physical surfaces and objects, and of their optic projection to the perceiver. Much computational research on vision contains these types of intentional and externalist components within the formal, mathematical, theories. Chomsky’s and Egan’s claims demonstrate inadequate study and understanding of Marr’s work and other research in this area. Computational theories of vision, by containing empirically based mathematical theories of visual content, to this extent present naturalizations of semantics. (shrink)

Unter den Versuchen Fichtes, sein Denken allgemeinverständlich darzustellen, zählt diese 1800 erschienene Schrift zu den inhaltlich abgerundetsten und aufschlußreichsten; bei den Zeitgenossen stieß sie jedoch auf vehemente Kritik, Hegel sah in ihr gar einen besonders illustrativen Text für den Aufweis der Haltlosigkeit der von Fichte in der Wissenschaftslehre vertretenen Position einer auf das Ich als Tathandlung gegründeten Philosophie. Darum vermag allein schon die Lektüre von Fichtes Bestimmung des Menschen und ihrer kritischen Rezeption in Hegels Glauben und Wissen einen Einblick in (...) die Gründe zu vermitteln, warum bis ins 20. Jahrhundert die Philosophie Fichtes weitgehend als ein merkwürdiger Mosaikstein auf dem Wege "Von Kant bis Hegel" oder, im Hinblick auf den "Endpunkt" dieses Wegs wohl genauer, in der "Entwicklung des Spinozismus" betrachtet wurde. Deutlich wird einer neuen Lektüre aber auch, wieviel noch zu tun bleibt, um die wichtigen Erkenntnisse, die im Deutschen Idealismus auf so getrennten Bahnen gewonnen wurden, im Blick auf die gemeinsamen Grundprobleme einer "Ersten Philosophie" ohne Rückfall in die traditionellen Feindbilder wahrzunehmen und kritisch in die pluralistische Diskussion heutigen Philosophierens einzubringen.

We claim that adjustable parameters play a crucial role in building and applying simulation models. We analyze that role and illustrate our findings using examples from equations of state in thermodynamics. In building simulation models, two types of experiments, namely, simulation and classical experiments, interact in a feedback loop, in which model parameters are adjusted. A critical discussion of how adjustable parameters function shows that they are boon and bane of simulation. They help to enlarge the scope of simulation far (...) beyond what can be determined by theoretical knowledge, but at the same time undercut the epistemic value of simulation models. (shrink)

The display of artefacts always implies an external mediation that influences, and often codifies, the reception of the exhibits. Objects are manipulated, restored, appropriated, staged, in short displayed, through various representational strategies that include pedestals, labels, and showcases. These elements, that we could define as parerga, are often ignored because of their utilitarian function. Yet, they play an important role in the history of the artefacts and define the setting in which the objects can exert their agency. They not only (...) shape their meaning, but also determine the effect that these artefacts have on their viewers. Framing devices create the conditions for interactions between the individual and the object to take place. This publication aims to explore the relation between artefacts and viewers as they are manifested in framing devices, and to develop a new theoretical framework for thinking about the power of objects on display.

Ouvrage inédit de Bernard Charbonneau, qui pourtant l'affectionnait beaucoup, ce petit livre est l'ultime réflexion qu'il porta sur le concept de liberté, qui chez lui a toujours été central. Il y offre à son lecteur une méditation de tout premier ordre mais accessible et concise sur la liberté, prise en tant que concept et recherche incarnés dans un temps, dans un lieu, dans un individu. Plus importante encore que la réflexion philosophique est la volonté de Charbonneau de tenter (...) de communiquer au lecteur qui lui fait l'amitié de le lire son expérience de la liberté, en se basant sur des figures irréfutables comme Rousseau (à travers le Contrat social), Montaigne (à travers les Essais), Berdiaev (à travers De l'Esclavage et de la liberté de l'homme) et Dostoïevski (à travers la parabole du Grand Inquisiteur), utilisées comme autant de perspectives différentes et de témoins édifiants." -- Page 4 of cover.

This chapter explores the ideological dimension of dehumanization in the context of National Socialism, focusing on the connection between concepts of humanity and dehumanizing images. NS regarded itself as a political revolution, realizing a new concept of humanity. Nazi ideologues undergirded the self-understanding of NS by developing racist anthropologies. I examine two major strands of Nazi ideology, focusing on their diverging strategies of dehumanization, and arguing that they were dependent on different anthropological frameworks. Richard Walther Darré held a naturalistic concept (...) of humanity and advanced biologistic forms of dehumanization. Alfred Rosenberg developed a dualistic anthropology that combined metaphysical and natural features. He dehumanized certain groups of people by reducing them to being human in a natural sense only. Moreover, I aim to show that the key motifs of these racist worldviews were prevalent in the scientific and philosophical debates on anthropology in early-twentieth-century Germany. I thus explore the general orientation of both the naturalistic and the anti-naturalistic strand in anthropological thought, unfold the animalizing tendencies of these views, and emphasize their conformity with the key motifs of Nazi ideology. The case of NS should thus exemplify the dehumanizing potential of anthropological theories. (shrink)

Qu'ont en commun Cioran, Simone Weil, Curzio Malaparte, Denis de Rougemont et les autres intellectuels et écrivains dont l'oeuvre et la vie sont évoquées dans ces pages? Il apparaît que, pour la plupart, ce sont des témoins d'une époque à bien des égards exceptionnelle, ne serait-ce que par la profondeur et l'intensité des malheurs qui y ont connu les hommes et les femmes. Mais alors pourquoi avoir choisi parmi tous les témoins possibles ceux qui, sans être inconnus dans les cercles (...) savants, ne le sont pas moins aujourd'hui du grand public? Peut-être s'agit-il de faire oeuvre d'éducation en permettant aux lecteurs d'accéder à la connaissance de ces témoins peu connus? Peut-être s'agit-il plutôt, à terme, de simplement rappeler ces existences marquées, au milieu de la tourmente, par la lucidité et le courage? Une telle entreprise peut paraître suspecte à une époque qui se targue d'avoir aboli toutes les idoles. Que vaut, en somme, ce type de célébration posthume dès lors que chaque existence, même la plus noble, porte en elle une part d'obscurité si déterminante? A cela s'ajoute que l'histoire, du moins celle que nourrit la recherche et que l'on enseigne dans les universités et les collèges, n'offre plus de modèles de vie, mais bien des faits, des explications et des interprétations que l'on souhaite les plus objectifs possible. Et pourtant, à cette époque que l'on dit de toutes les fins, de l'Art, de l'Histoire, de l'Homme, il a semblé nécessaire de renouer avec l'esprit de la tradition humaniste. Un jardin en soi, aurait pu écrire Montaigne, qu'on ne peut cultiver pour le mieux, car c'est là un art incertain, qu'en ayant à l'esprit un certain idéal. Or, renouer ainsi le fil rompu de la transmission de l'Idéal, tel était, et tel demeure encore aujourd'hui, notre volonté en publiant ces figures de pensée. (shrink)

Quand le gouvernement de René Lévesque mit fin au financement occulte des partis politiques en 1977, les démocrates de tous les horizons se mirent à croire qu’il était possible d’éliminer la corruption systémique qui gangrène la vie publique partout dans le monde.

La naissance de la philosophie s'accompagne d'un refus énigmatique, celui de l'exil. Persécuté par Athènes, Socrate choisira de se donner la mort plutôt que de vivre les dernières années de sa vie à errer hors de ses murs. Par ce refus qui résonne par-delà les siècles jusqu'à nous, Socrate nous oblige à réfléchir à ce lien intime entre l'individu et sa communauté d'origine. Dans l'histoire de la vie de l'esprit, tous ne feront pas le même choix. Plusieurs, écrivains, poètes, philosophes, (...) préféreront la vie ailleurs à la persécution ou à la mort certaine. Comment l'exil ou les longues périodes d'errance ont-ils influencé ceux qui en ont fait l'expérience? Leur témoignage nous permet-il de penser les défis particuliers de notre époque? De manière plus précise, est-ce que la pensée des auteurs qui ont vécu l'exil est de nature à nous inciter à célébrer davantage les vertus de l'enracinement ou au contraire nous convie-t-elle à souhaiter qu'advienne encore plus rapidement un monde cosmopolite? À l'heure où les enjeux migratoires deviennent de plus en plus pressants et où est remise en question de multiples manières la pertinence des frontières, la pensée de ceux qui ont connu l'exil doit éclairer notre réflexion.

Zunächst Pfarrer in Berlin-Charlottenburg, dann Professor für Philosophie in Halle, repräsentiert Eberhard die nachwolffianische deutsche Popularphilosophie, der an praktisch und pädagogisch wirksamer Aufklärung im Zusammenspiel mit den fortschrittlichen politischen und religiösen Kräften lag. In diesen Lehrbüchern repräsentiert Eberhard sich als Aufklärer auf dem philosophischen Niveau der ästhetischen, hermeneutischen und historischen Modifikation des Wolffschen Systems und der neuerlichen Rezeption der Philosophie Leibniz’, zumal der Erkenntnistheorie der 1765 erschienenen „Nouveaux essais sur l’entendement humain“. Eberhard wurde aufgrund seiner Theorie des Denkens und Empfindens (...) als Schüler Leibniz’ bezeichnet; und er verfasste denn auch eine Leibniz-Biographie. Er hielt zeitlebens an den wolffianischen Standards von Rationalität fest und widersetzte sich nicht nur dem normativen Rekurs auf „Empfindsamkeit“ in Literatur und Religion, sondern auch der sog. Glaubensphilosophie Friedrich Heinrich Jacobis, erst recht der zeitgenössischen Wiederkehr von Okkultismus und Esoterik. Johann August Eberhard, professor of philosophy in Halle, is one of the foremost exponents of the Popularphilosophie of the German Enlightenment. He was a major contributor to Friedrich Nicolai’s "Allgemeine Deutsche Bibliothek", and advanced unorthodox opinions on religious and political issues. (shrink)
