Kritische Theorie und Philosophische Anthropologie gelten noch immer als grundsätzlich einander widerstreitende Strömungen. Die Philosophien Helmuth Plessners und Theodor W. Adornos jedoch lassen sich, so die These dieses Buches, unter dem Namen der negativen Anthropologie zusammenführen. Edinger begreift negative Anthropologie im systematischen Sinn als strukturell negativ verfasstes Konzept, um elementare und exklusive Gemeinsamkeiten zwischen Adorno und Plessner sichtbar zu machen. Neben den grundsätzlichen Überlegungen, u.a. zum Konzept der Anthropologie bei Sonnemann und Gehlen, widmet sich der Autor auch beispielhaft den Motiven (...) der Kritik der Moderne und die Kritik der Geschichtsphilosophie durch Plessner und Adorno. Damit erreicht er eine neue Sicht auf das Verhältnis der beiden philosophischen Richtungen, die die gemeinhin akzeptierte unversöhnliche Frontstellung von philosophischer Anthropologie und Kritischer Theorie aufhebt.

While largely studied because of their harmful effects on human health, there is growing appreciation that bacteria are important partners for invertebrates and vertebrates, including man. Epithelia in metazoans do not only select their microbiota; a coevolved consortium of microbes enables both invertebrates and vertebrates to expand the range of diet supply, to shape the complex immune system and to control pathogenic bacteria. Microbes in zebrafish and mice regulate gut epithelial homeostasis. In a squid, microbes control the development of the (...) symbiotic light organ. These discoveries point to a key role for bacteria in any metazoan existence, and imply that beneficial bacteria‐host interactions should be considered an integral part of development and evolution.

It is well known that Sartre describes his form of existentialism as atheistic, and much of the rhetoric of Sartrean existentialism draws off the image of God's absence from the world. There are nevertheless, I argue, deep grounds for thinking that the coherence and well-groundedness of Sartre's thought requires that his phenomenological ontology take finally the form of an onto-theology: Sartre's ontology runs into difficulties concerning the origin of the for-itself and the unity of being; an onto-theology like Schelling's, which (...) avoids the ‘ontological optimism’ that Sartre objects to in Hegel, both releases Sartre's ontology from its difficulties and furthers Sartre's central philosophical purposes.

In this work we present a dynamical approach to quantum logics. By changing the standard formalism of quantum mechanics to allow non-Hermitian operators as generators of time evolution, we address the question of how can logics evolve in time. In this way, we describe formally how a non-Boolean algebra may become a Boolean one under certain conditions. We present some simple models which illustrate this transition and develop a new quantum logical formalism based in complex spectral resolutions, a notion that (...) we introduce in order to cope with the temporal aspect of the logical structure of quantum theory.

The so-called classical limit of quantum mechanics is generally studied in terms of the decoherence of the state operator that characterizes a system. This is not the only possible approach to decoherence. In previous works we have presented the possibility of studying the classical limit in terms of the decoherence of relevant observables of the system. On the basis of this approach, in this paper we introduce the classical limit from a logical perspective, by studying the way in which the (...) logical structure of quantum properties corresponding to relevant observables acquires Boolean characteristics.

Baldwin, T. (ed.) Cambridge History of Philosophy 1870 -1945.

In this blog entry, which addresses a broader audience, I wonder what exactly historians of philosophy do and how their work relates to non-historical work in philosophy. In particular, I raise the question why systematic philosophers and historians of philosophy are relatively close to each other. After all, they often publish in the same journals and work at the same departments. This is surprising, given that asking what X is seems to be rather different from asking what some person a (...) few hundred (or thousand) years ago thought what X is. I argue that systematic philosophers and historians of philosophy are so close because their work proceeds in a similar way. To be sure, they have very different starting points. Historians of philosophy may start, for instance, with a number of texts from one and the same author which appear to be in conflict. Systematic philosophers, in contrast, may start with a set of intuitions which seem to contradict one other. The way historians of philosophy and systematic philosophers operate upon those different starting points, however, is very similar. This explains at least in part, I maintain, why they are a lot closer than is the case in many other disciplines. (shrink)

Contemporary business often encompasses or aspires towards the automated, networked production of industrial goods across transnational supply chains that have many digitalized interfaces. This allows competitive operations in time, costs, and quality, which have been widely discussed. On the downside, it entails cyber threats with significant risks for society in areas including business, environment, and health. Hence, to adequately manage these risks in the emerging digital world, there is a vital necessity to raise awareness, establish, maintain, and further develop cyber-security (...) measures to ensure an appropriate level of protection along the entire value chain and supply chain. Blockchain capabilities are introduced to improve the technical and organizational basis for secured operations in industrial networks. Its advantages are explained by a simple USB-device use case, that has often been the root cause to subsequent security incidents, especially in the Stuxnet incident. (shrink)

The discussion is a response to Dews on the question of how Schelling's Freiheitsschrift should be interpreted. It falls into two halves, the first defending my interpretation, and the second expanding on the case that Dews makes for the unavoidability of metaphysics in the theory of human freedom, with which I am in full agreement. The main criticism that Dews makes of my reading is that the argument I attribute to Schelling concerning the metaphysical significance of evil rests on Kantian (...) assumptions regarding the existence of pure practical reason, which Schelling rejects. I argue that, though certainly matters are more complicated than my earlier discussion made them seem, Schelling remains sufficiently close to Kant for the argument I attribute to avoid inconsistency. In the second half I raise what I claim to be a neglected but important question: Why is the legacy of classical German philosophy not regarded as significant for contemporary discussion of human freedom? My answer in brief is that the concept of freedom has undergone a profound contraction. In this context I also try to define more precisely what is distinctive of Schelling's view of human freedom.

We define an applicative theory of truth TPTTPT which proves totality exactly for the polynomial time computable functions. TPTTPT has natural and simple axioms since nearly all its truth axioms are standard for truth theories over an applicative framework. The only exception is the axiom dealing with the word predicate. The truth predicate can only reflect elementhood in the words for terms that have smaller length than a given word. This makes it possible to achieve the very low proof-theoretic strength. (...) Truth induction can be allowed without any constraints. For these reasons the system TPTTPT has the high expressive power one expects from truth theories. It allows embeddings of feasible systems of explicit mathematics and bounded arithmetic.The proof that the theory TPTTPT is feasible is not easy. It is not possible to apply a standard realisation approach. For this reason we develop a new realisation approach whose realisation functions work on directed acyclic graphs. In this way, we can express and manipulate realisation information more efficiently. (shrink)

Starting from Kant’s conception of critique as »Grenzziehung,« the immanent representation of being, or, the conscious world, is understood as a screening off of its noumenal ground. Materially bound images gain a particular function in the explication of the structure of this immanence. As objects within the phenomenal world they duplicate the world’s phenomenal- ity in the dimension of iconic semblance by (partially) negating their material support. This cleavage between the image’s phenomenality and its materiality makes images into possible catalysts (...) of a critique of natural consciousness, be it individual or collective. Thus, »image critique« can serve as a hinge between a transcendental critique of consciousness and a critique of ideology or spectacle. (shrink)

This paper aspires to show the often-obscured structure of alternatives in education. Alternative education is generally understood as an umbrella term for educational thought and practice for and in schools differing from an assumed ‘mainstream’, where ‘alternative’ is often taken to mean ‘better’. In many cases, ‘mainstream’ serves as an empty signifier that can be substituted by various forms of criticism. Just as progressive education is supposed to remedy all the ills of traditional education, alternative education is often positioned as (...) a safe place to retreat to, away from the mainstream. I argue that this leads to a dichotomous structure. The mainstream, however, is not an empirical reality, for example, a specific form of curriculum, differentiation of different types of schooling, or anything else. ‘Mainstream’ serves as a generic critical reference point. My argument is developed through a series of historical discussions around alternative education explored through the lens of contemporary analysis of the category. I then offer a more systematic account of the terminology in order to establish a perspective from which to assess the flaws and problems of alternative education alongside its potential virtues and benefits.

Oswald Spenglers Kulturmorphologie diente als Ausgangspunkt einer internationalen und interdisziplinär angelegten Tagung, deren Beiträge in diesem Band vorliegen. Sie behandeln eine Vielfalt an Themen, die von der Menschwerdung, über die Kulturen des Altertums bis hin zu aktuellen politischen und sozialen Fragestellungen reichen. Schließlich sind auch Studien zur Spenglerforschung im engeren Sinne vertreten.

Before an aggregation of persons can be said to constitute a community there must exist a sharing of a body of norms or values, or asystem of beliefs or morals. In sociology this conception frequentlyappears in the term “consensus,” and in political science a similar conception goes by the phrase “social contract.” The two conceptions are not identical and an important point of difference will be touched on later, but according to this position knowledge of and adherence to the fundamental (...) rules is necessary to group unity or cohesion.

This paper argues that even Crane’s modified account of belief doesn’t do justice to all varieties of religious belief. Particularly beliefs associated with ritual behavior don’t seem to match the criteria of Crane’s alternative account. So, the question remains whether these beliefs should still be called beliefs, or whether the standard model of belief is even more false than Crane suspects.

People tend to grossly overestimate the size of their mirror-reflected face. Although this overestimation bias is robust, not much is known about its relationships to self-face perception. In two experiments, we investigated the overestimation bias as a function of the presentation of the own face , the identity of the seen face, and prior exposure to a real mirror. For this we developed a computerized task requiring size estimations of displayed faces. We replicated the observation that people overestimate the size (...) of their mirror-reflected face and showed that the overestimation can be reduced following a brief mirror exposure. We also found that left–right reversal modulates the overestimation bias, depending on the perceived face’s identity. These data underline the enhanced familiarity of left–right reversed self-faces and the importance of size perception for understanding mirror reflection processing. (shrink)

Problem ukrytości Boga staje się coraz częściej dyskutowanym tematem filozoficznym. W swoim artykule chciałbym zająć się kwestią nazwaną przez Jacka Wojtysiaka (w jego książce Między jawnością a ukryciem) (Wojtysiak 2023) „wiedzą testymonialną” i powiązać ją z Newmanowską koncepcją rozumowania implikatywnego. Odróżnienie od siebie dwóch rodzajów rozumowania — jednego spontanicznego, praktycznego, znajdującego swoje zastosowanie m.in. w obszarze wiary i moralności, oraz drugiego krytycznego, analitycznego i retrospektywnego, używanego w nauce, a także w filozofii i teologii – wydaje mi się kluczowe dla zrozumienia (...) obserwowalnej ukrytości Boga.
