A "practical discourse" is a collective deliberation organized in such a way as to guarantee optimally unrestrained exchange of arguments; the result should be a decision, e.g. acceptance of a collectively binding norm of action, expressing a rational consensus. Juergen Habermas argues that the choice of entering a "practical discourse" in order to resolve conflict is not arbitrary but is rather "rationally motivated"; speakers of any language whatsoever "unavoidably" share certain normatively binding presuppositions, amongst which is that they expect (...) of one another that they will enter "discourse". ;The present essay is an attempt to test the grounds for the claim that general conditions of communication make "discourse" "unavoidable". It excavates arguments that Habermas rather suggests than explicitly presents, and attempts to give them clear form suitable for critical evaluation. There seem to be about three arguments for his claim: from the nature of "speaking subjects"; from the general conditions of "communicative action"; from the alleged promissory force of illocutions of everyday language. ;Critical evaluation shows that these arguments are insufficient to establish the "thesis of unavoidability". The thesis itself is fatally ambiguous ; the arguments often beg the question. Habermas also fails to distinguish between the project of describing language-use and the project of justifying its rationality for, granting that we had the reciprocal expectations of which he speaks, further argumentation would be required to show that we were rational, let alone moral, for having such expectations. ;Finally, it is determined that Habermas' theory of "communicative action" is itself inconsistent with the project of grounding an obligation to "discourse" in the conditions of "communicative action". According to the latter, obligations must be justified in "discourses"; thus, no argument showing speakers share normative expectations would ipso facto show those expectations are obligatory of "normatively valid".

an overly long draft of an encyclopedia article forthcoming in History of Continental Thought, Volume 6: Poststructuralism and Critical Theory: The Return of Master Thinkers, ed. Alan D. Schrift (Acumen Press).

The relationship between being and consciousness has been characterised as one of alienation , reification , instrumentalization , and 'one dimensionalization' . More recently Jurgen Habermas has described the 'colonization of the lifeworld'. Each of these theorists argues that social and political philosophy has two primary tasks. First, a political philosophy should construct a model of how we might best structure our social and political situation so as to maximize freedom and self-determination. Second, a political philosophy should provide an (...) analysis of presently existing conditions. The gap between the model and the actually existing reality provides the space for social and political criticism, as well as social and political struggle. In his account of 'the colonization of the lifeworld', Habermas attempts to explain the relation between being and consciousness in terms of his theory of communicative action and to locate possible points of social and political crisis in advanced capitalist society. ;In this dissertation I trace theories of the relationship between being and consciousness from Marx through Lukacs and the Frankfurt School to Habermas' recent work The Theory of Communicative Action. I argue that in terms of his stated goal of providing a critical social theory with practical intent Habermas has been only partially successful. I present an account of Habermas' theory and claim it is potentially more politically efficacious than post-structuralist theories, though only if his theory is attentive to the concerns of those same post-structuralist theories. After arguing that at a certain level of abstraction Habermas is right in his account of our present situation, I conclude that he falls short of his goal in so far as his theory fails to take adequate account of many actually existing struggles for political self-determination, and many hypotheses for alternative social organization which do not agree with his assumptions about validity and consensus.

The debate between Jurgen Habermas and Charles Taylor is reflective of the enduring conflict between liberal philosophy with its emphasis upon freedom, equality, and legal rights, and Aristotelianism with its accent upon the cultivation of virtue, personal responsibility and shared notions of the Good. Though grounded in opposite ends of the philosophical spectrum, both men remain critical of the burgeoning effects of instrumental rationality and the social atomization and anomie it continues to generate; both understand the extent to which (...) the self is a social construct and the role of interpersonal intersubjectivity in the development of their individual and collective identities; both argue for the centrality of certain goods in maintaining a minimal degree of social cohesion; and both affirm that the crucial feature of human life is communication and its dialogical character. ;To overcome the adverse manifestations of our positivistic ethos with its over-reliance upon purposive-instrumental reason, each has responded with a countervailing notion of rationality---"phronesis" or Aristotelian practical reason for Taylor and "communicative reason" for Habermas. Each's choice of reason has led to profound differences in their respective notions of the self as well as fundamental incongruities in their moral and political philosophies. In the interest of preserving the autonomy and integrity of the individual while yet affirming universal justice, Habermas argues for the formalism of a "proceduralistic" ethics. Taylor, on the other hand, advocates a "substantialist" one, a communal ethics that arises from out of people's deepest moral intuitions; an ethics bound up with historical values and ideals that stresses the cultivation of virtue and shared notions of the common good. ;I argue that although Habermas's "communicative action" with its focus upon intersubjective communication helps to bridge the competing philosophies of communitarianism and classical liberalism, a basic incommensurability still persists. However, rather than being mutually exclusive, there needs to be a creative, dialectical tension maintained between them whereby each continues to inform and influence the other. In this way, a postmodern ethics rooted in dialogue and communication can be constructed which maintains people's integrity and autonomy while similarly addressing their multiple needs and concerns, but also an ethics grounded in one's deepest moral intuitions which remains sensitive to the concrete, historical, and particularistic distinctions which differentiate their identities.

Both the pragmatic logic of social critique and the idea of a critical social theory presuppose the possibility of distinguishing progressive from regressive forms of social change. Thus, a condition of adequacy of social critique in general, and of critical social theory in particular, is the theoretical capacity to identify progressive social change. I begin this study by showing that, since it incorporates a theory of social evolution, Habermas's conception of critical social theory satisfies this condition. ;Habermas's theory (...) of social evolution, however, is a source of much misunderstanding in the literature. I attempt to clarify the theory with a careful reconstruction of its concepts and fundamental theses, and by systematizing the theory as a whole. The central thesis of the theory of social evolution that functions to identify progressive change is that the logic and the content of social change can be distinguished, and that we can rationally reconstruct the developmental logic of the normative structures of societies. I analyze the concept of developmental logic and defend it against some common objections, including the objection that the theory draws a false analogy between the structures of individual maturation and social rationalization. This 'ontogenetic fallacy' is not committed, I argue, because Habermas translates only the formal features of the concept of developmental logic from its genesis in psychology to social theory. ;I conclude by arguing that Habermas's theory of social evolution does entail an adequate conception of progress, but that it is insufficiently differentiated. That is, Habermas's theory explains progress in each of the dimensions of cognitive knowledge and moral insight; but it lacks an explanation of progress in the dimension of expressive self-realization. Drawing upon the conceptual resources of Habermas's theory, I show that it can account for this dimension if it also includes a notion of expressive action that is pre-discursive. (shrink)

Habermas discusses the chances for the establishment of world citizenship in contemporary society, marked by multiculturalism and the process of globalization. Habermas identifies the historical configuration of the post-national constellation, and from there themed the transition from international law to the law of citizens of the world, which aligns the concept of citizenship to the idea of ​​human rights. Habermas analyzes the Kantian idea of ​​a cosmopolitan state in which citizens are legal subjects of their respective States (...) and members of a cosmopolitan entity. Kant elaborates on the concept of world republic, which Habermas disagrees with, but offers the example of the European Union for a discussion on the realization of a just and peaceful international order. Based on the Kantian orientation of constituting an order of world citizenship, Habermas discusses the conformation and viability of this idea in contemporary times. For Habermas, it is possible to spell out the idea of ​​cosmopolitan citizenship. From the European Union, cooperation between States and citizens shows that a cosmopolitan community is needed to complement an international community of States. (shrink)

For some time now a number of critics have argued that Juergen Habermas has misinterpreted Freud. The gist of this criticism is that Habermas' interpretation of psychoanalysis as `depth hermeneutics' must violate the intent of Freud's work, which is so deeply grounded in drive theory. In other words, Habermas confuses philosophical reflection with psychoanalysis. This paper takes a somewhat different focus. It examines the consequences of Habermas' interpretation of Freud for Habermas' view of the individual. (...) It is shown that Habermas' interpretation eventuates in an abstract and shadowy view of the individual. It is argued that an alternative view of psychoanalysis, object relations theory, can help locate the source of Habermas' pale view of the individual, and help correct it, without succumbing to `neo-Freudian revisionism'. Object relations theory also suggests that in order to overcome the diminution of the individual in real life it is necessary for political theory to examine seriously the role of the family. Finally, object relations theory generates an interesting criticism of so-called postmodern psychoanalysis—for example, the work of Jacques Lacan. This criticism can help us better understand the relationship between Habermas and modernism. (shrink)

This article sketches an idealized strategy for the identification of neural correlates of consciousness. The proposed strategy is based on a state space approach originating from the analysis of dynamical systems. The article then focuses on one constituent of consciousness, phenomenal awareness. Several rudimentary requirements for the identification of neural correlates of phenomenal awareness are suggested. These requirements are related to empirical data on selective attention, on completely intrinsic selection and on globally unconscious states. As an example, neuroscientific findings on (...) synchronized γ activity are categorized according to these requirements. (shrink)

Philosophical discussions on causal inference in medicine are stuck in dyadic camps, each defending one kind of evidence or method rather than another as best support for causal hypotheses. Whereas Evidence Based Medicine advocates the use of Randomised Controlled Trials and systematic reviews of RCTs as gold standard, philosophers of science emphasise the importance of mechanisms and their distinctive informational contribution to causal inference and assessment. Some have suggested the adoption of a pluralistic approach to causal inference, and an inductive (...) rather than hypothetico-deductive inferential paradigm. However, these proposals deliver no clear guidelines about how such plurality of evidence sources should jointly justify hypotheses of causal associations. We here develop such guidelines by first giving a philosophical analysis of the underpinnings of Hill’s viewpoints on causality. We then put forward an evidence-amalgamation framework adopting a Bayesian net approach to model causal inference in pharmacology for the assessment of harms. Our framework accommodates a number of intuitions already expressed in the literature concerning the EBM vs. pluralist debate on causal inference, evidence hierarchies, causal holism, relevance, and reliability.

According to the objective Bayesian approach to inductive logic, premisses inductively entail a conclusion just when every probability function with maximal entropy, from all those that satisfy the premisses, satisfies the conclusion. When premisses and conclusion are constraints on probabilities of sentences of a first-order predicate language, however, it is by no means obvious how to determine these maximal entropy functions. This paper makes progress on the problem in the following ways. Firstly, we introduce the concept of a limit in (...) entropy and show that, if the set of probability functions satisfying the premisses contains a limit in entropy, then this limit point is unique and is the maximal entropy probability function. Next, we turn to the special case in which the premisses are categorical sentences of the logical language. We show that if the uniform probability function gives the premisses positive probability, then the maximal entropy function can be found by simply conditionalising this uniform prior on the premisses. We generalise our results to demonstrate agreement between the maximal entropy approach and Jeffrey conditionalisation in the case in which there is a single premiss that specifies the probability of a sentence of the language. We show that, after learning such a premiss, certain inferences are preserved, namely inferences to inductive tautologies. Finally, we consider potential pathologies of the approach: we explore the extent to which the maximal entropy approach is invariant under permutations of the constants of the language, and we discuss some cases in which there is no maximal entropy probability function.

Narrative allegory is distinguished from mythology as reality from symbol; it is, in short, the proper intermedium between person and personification. Where it is too strongly individualized, it ceases to be allegory […]. In the community of scholars of intermedia research, the above quoted citation is commonly regarded as Coleridge’s coining of the term “intermedium” or “intermediality”. However, a short glance at the discursive strategy of his argument emphasizes that his notion of “intermedium” must be closely linked to the poetics (...) and aesthetics of 19th-century romanticism. For the romantic poet, the term of “intermedium” does not point to media relations or intermedia processes but to.. (shrink)

We study questionnaire responses to situations in which sacrificing one life may save many other lives. We demonstrate gender differences in moral judgments: males are more supportive of the sacrifice than females. We investigate a source of the endorsement of the sacrifice: antisocial preferences. First, we measure individual proneness to spiteful behavior, using an experimental game with monetary stakes. We demonstrate that spitefulness can be sizable—a fifth of our participants behave spitefully—but it is not associated with gender. Second, we find (...) that gender is consistently associated with responses even when we account for individual differences in the propensity to spitefulness. (shrink)

As digital media becomes more central to the lives of adolescents, it also becomes increasingly relevant for their sexual communication. Sexting as an important image-based digital medium provides opportunities for self-determined digital communication, but also carries specific risks for boundary violations. Accordingly, sexting is understood either as an everyday, or as risky and deviant behavior among adolescents. In the affectedness of boundary violations gender plays an important role. However, it is still unclear to what extent digital sexual communication restores stereotypical (...) gender roles and restrictive sexuality norms or, alternatively, enables new spaces of possibility. In this sense, current research points to a desideratum regarding adolescents’ orientations toward sexting as a practice between spaces of possibility and boundary violations. This paper discusses the possibilities, but also the risks, of intimate digital communication among adolescents. The main question is, how adolescents themselves perceive sexting practices and how they position themselves between both spaces for possibility and for the exchange of unwanted sexual content. For this purpose, orientations toward normalities and gender of students are reconstructed. To answer these questions, twelve single-sex, group discussions were carried out with students aged 16 and 17 at five different secondary schools in northern Germany. A total of 20 boys and 22 girls took part. The group discussions were structured by a narrative generating guideline. The analysis draws its methodology from the Documentary Method, regarding implicit and explicit forms of knowledge and discourse. It results in a typology of three types with different orientations. The study shows, that most of the students consider sexting to be a risky practice; only one type shows normality in the use of sexting. At the same time, some of the young people are interested in experimenting with image-based intimate digital communication. Further, gender differences in use and affectedness are also documented. In this way, orientations toward gender stereotypes “favor” both the attribution of responsibility to girls, and overlook the responsibility of students who perpetrated the boundary violation. The orientations of adolescents should be taken more into account in research as well as in educational programs for the prevention of sexual violence. (shrink)

Augmented Reality (AR) is commonly defined as a digital layer of information viewed on top of the physical world through a smartphone, tablet or eyewear. Increasingly, this understanding of AR is shifting to a dynamic framework of ‘smart things’, including wearable technology, sensors and artificial intelligence (AI), with the ability to intercede in key moments and to deliver contextual and meaningful experiences. The things that come into context are the logical next steps in an evolutionary development towards computers that are (...) better able to show empathy in relation to people: even more human-oriented, anticipative and ubiquitous. Thus, this outsourcing of meaning to empathic technologies points to one of the fundamental questions concerning the relation of human and technology – the nature of the trust that users place in technology.

This paper presents the contributions of Alcindo Flores Cabral, professor of Chemistry at the Faculdade de Agronomia Eliseu Maciel, nowadays part of the Universidade Federal de Pelotas, to chemistry teaching. It is a contribution almost unknown to the Brazilian chemical community, although recognized as valuable by several renowned chemists abroad, like W. Hückel, G. Charlot, F. Strong, E. Fessenden and others. Cabral’s innovative helical representation is presented in connection not only with contemporary representations, but also an incursion is made into (...) the first helical systems proposed, those of Hinrichs and of Baumhauer. Some comments are made not only on Cabral’s Classificação Natural dos Elementos, published in 1946, but also about other texts he wrote for an efficient chemistry teaching. (shrink)

Epistemic scoring rules are the en vogue tool for justifications of the probability norm and further norms of rational belief formation. They are different in kind and application from statistical scoring rules from which they arose. In the first part of the paper I argue that statistical scoring rules, properly understood, are in principle better suited to justify the probability norm than their epistemic brethren. Furthermore, I give a justification of the probability norm applying statistical scoring rules. In the second (...) part of the paper I give a variety of justifications of norms for rational belief formation employing statistical scoring rules. Furthermore, general properties of statistical scoring rules are investigated. Epistemic scoring rules feature as a useful technical tool for constructing statistical scoring rules. (shrink)

O presente trabalho examina os aspectos históricos da extração do óleo de canela-sassafrás (Ocotea pretiosa Mez), rico em safrol, no Alto e Médio Vale do Itajaí, a partir de 1940, por iniciativa de Otto Grimm, no município de Rio do Sul. Apresenta-se o tema no contexto da memória química em Santa Catarina, e discutem-se os procedimentos utilizados, e principalmente os motivos que levaram tal indústria incipiente a não se converter em uma indústria de química fina. Para tanto, são apresentados alguns (...) dados pertinentes à química do safrol, indicando que tal indústria poderia ter evoluído, bem como os aspectos econômicos e sociais que, ao lado da proibição do corte da canela-sassafrás, levaram em 1990 à extinção definitiva dessa "química fina que poderia ter sido".

Dos diferentes fatores associados a uma mudança de paradigma e, portanto, a uma revolução química, o menos discutido é o que envolve os assim chamados experimentos exemplares, mudanças radicais na metodologia de trabalho e nos procedimentos empíricos da química, mudanças e modificações estas que, no caso de uma ciência natural empírica, podem ter como consequência dados experimentais antes inacessíveis, levando, por fim, a uma nova abordagem de conceitos, hipóteses e teorias e desencadeando uma "revolução" química, um novo paradigma. Muito mais (...) do que uma revolução química, dever-se-ia optar por uma gradativa evolução química. Escolhemos três dessas situações como "exemplares": a modificação no procedimento empírico da química pneumática, com o uso da cuba pneumática contendo mercúrio; a introdução de novos métodos de extração de compostos orgânicos naturais, com a substituição do método pirogênico pelo de extração com solventes; um novo entendimento de "análise química", com a substituição da comparação de amostras tidas como autênticas pela decomposição do analito.

The chemist Max von Pettenkofer studied with Justus von Liebig, and after leaving Giessen in 1844 did not immediately find an academic position. During the period 1844/1845 he wrote a cycle of 16 Chemical Sonnets, but published them only in 1886. The Sonnets have with few exceptions a historiographical character. We present a translation of the Sonette into Portuguese as well as commentaries about their content and their philosophical significance. We also comment rather briefly on Pettenkofer’s career as an empirical (...) chemist and later as a somewhat heterodox hygienist. (shrink)

In this essay, we aim to provide an overview of the periodic table’s origins and history, and of the elements which conspired to make it chemistry’s most recognisable icon. We pay attention to Mendeleev’s role in the development of a system for organising the elements and chemical knowledge while facilitating the teaching of chemistry. We look at how the reception of the table in different chemical communities was dependent on the local scientific, cultural and political context, but argue that its (...) eventual universal acceptance is due to its unique ability to accommodate possessed knowledge while enabling novel predictions. Furthermore, we argue that its capacity to unify apparently disconnected phenomena under a simple framework facilitates our understanding of periodicity, making the table an icon of aesthetic value, and an object of philosophical inquiry. Finally, we briefly explore the table’s iconicity throughout its representations in pop art and science fiction. (shrink)
