Peer review is a widely accepted instrument for raising the quality of science. Peer review limits the enormous unstructured influx of information and the sheer amount of dubious data, which in its absence would plunge science into chaos. In particular, peer review offers the benefit of eliminating papers that suffer from poor craftsmanship or methodological shortcomings, especially in the experimental sciences. However, we believe that peer review is not always appropriate for the evaluation of controversial hypothetical science. We argue that (...) the process of peer review can be prone to bias towards ideas that affirm the prior convictions of reviewers and against innovation and radical new ideas. Innovative hypotheses are thus highly vulnerable to being “filtered out” or made to accord with conventional wisdom by the peer review process. Consequently, having introduced peer review, the Elsevier journal Medical Hypotheses may be unable to continue its tradition as a radical journal allowing discussion of improbable or unconventional ideas. Hence we conclude by asking the publisher to consider re-introducing the system of editorial review to Medical Hypotheses. (shrink)

People often struggle with Bayesian reasoning. However, research showed that people’s performance (and rationality) can be supported by the way of representing the statistical information. First, research showed that using natural frequencies instead of probabilities as format of statistical information increases people’s performance in Bayesian situations thoroughly. Second, research also yielded that people’s performance increases through using visualization. We build our paper on existing research in this field. The main aim is to analyse people’s strategies in Bayesian situations that are (...) still erroneous although statistical information is represented by natural frequencies and visualizations. In particular, we compare two pairs of visualization with similar numerical information (tree diagram vs. unit square and double-tree diagram vs. 2x2-table) concerning their impact on people’s erroneous strategies in Bayesian situations. For this aim, we conducted an experiment with 540 university students. The students were randomly assigned to four conditions that are defined by the four different visualizations of statistical information. The students were asked to indicate a fraction as response in four Bayesian situations. We documented the numerator and the denominator of the students’ responses representing a basic set and a subset in a Bayesian situation. Our results show that people’s erroneous strategies are highly dependent on the visualization. A central finding is that the visualization’s characteristic of making the nested-sets structure of a Bayesian situation transparent has a facilitating effect on people’s Bayesian reasoning. For example, compared to the unit square, a tree diagram does not explicitly visualize the set-subset relations that are relevant in a Bayesian situation. Accordingly, compared to a unit square, a tree diagram partly hinders people to find the correct denominator in a Bayesian situation, and, in particular, triggers to select a wrong numerator. By analyzing people’s erroneous strategies in Bayesian situations, we contribute to investigating approaches to facilitate Bayesian reasoning and to further develop the teaching of Bayesian reasoning.

Der Ausdruck ›Bewusstsein‹ hat viele Bedeutungen. Zu den wichtigen Bedeutungsfacetten gehören: wach sein, auf etwas aufmerksam sein, etwas mit Absicht tun, sich seiner selbst bewusst sein, eine Empfindung verspüren. Daraus ergibt sich folgende Unterteilung :Vigilanzbewusstsein Kognitives Bewusstsein Handlungsbewusstsein Selbstbewusstsein Phänomenales Bewusstsein Menschen verfügen über alle sechs Arten Bewusstsein. Es ist eine offene Frage, ob dies auch auf Tiere zutrifft. Bei Säugern und Vögeln scheint es nahe zu liegen, dass sie über Bewusstsein im Sinne von, und verfügen. Offen bleibt, ob bestimmte (...) Vögel oder Säugetiere etwas mit Absicht tun können und ob sie über Selbstbewusstsein im Sinne eines Zugangs zu den eignen psychischen Zuständen verfügen. Es gibt bei Menschenaffen, Walen oder Rabenvögeln deutliche Hinweise darauf, dass sie in der Kommunikation bestimmte Absichten mitteilen wollen und möchten, dass die Rezipienten diese Absichten richtig verstehen. Bei Delfinen finden sich Hinweise aus dem Bereich der Forschung zur ›Metakognition‹, die besagen, dass bestimmte Tiere Zugang zu ihren psychi­schen Zuständen haben und dies in der Entscheidungsfindung miteinbeziehen. Verlässt man diese beiden Tierklassen wird einiges unklar. Bei Fischen oder Insekten etwa stellt sich die Frage, inwiefern sie überhaupt über einen Schlaf-Wach-Zyklus verfügen. Man kann durchaus die Auffassung vertreten, dass die Unterscheidung von Schlaf- und Wachphasen eine Voraussetzung dafür ist, bei einem Tier überhaupt von Bewusstsein zu sprechen, denn die Fähigkeit aufzuwachen scheint die basalste Form von Bewusstsein zu sein.

A provocative argument that environmental thinking would be better off if it dropped the concept of “nature” altogether and spoke instead of the built environment. -/- Environmentalism, in theory and practice, is concerned with protecting nature. But if we have now reached “the end of nature,” as Bill McKibben and other environmental thinkers have declared, what is there left to protect? In Thinking like a Mall, Steven Vogel argues that environmental thinking would be better off if it dropped the (...) concept of “nature” altogether and spoke instead of the “environment”—that is, the world that actually surrounds us, which is always a built world, the only one that we inhabit. We need to think not so much like a mountain (as Aldo Leopold urged) as like a mall. Shopping malls, too, are part of the environment and deserve as much serious consideration from environmental thinkers as do mountains. -/- Vogel argues provocatively that environmental philosophy, in its ethics, should no longer draw a distinction between the natural and the artificial and, in its politics, should abandon the idea that something beyond human practices (such as “nature”) can serve as a standard determining what those practices ought to be. The appeal to nature distinct from the built environment, he contends, may be not merely unhelpful to environmental thinking but in itself harmful to that thinking. The question for environmental philosophy is not “how can we save nature?” but rather “what environment should we inhabit, and what practices should we engage in to help build it?”. (shrink)

Are our beliefs justified only relatively to a specific culture or society? Is it possible to give reasons for the superiority of our scientific, epistemic methods? Markus Seidel sets out to answer these questions in his critique of epistemic relativism. Focusing on the work of the most prominent, explicitly relativist position in the sociology of scientific knowledge – so-called 'Edinburgh relativism' or the 'Strong Programme' –, he scrutinizes the key arguments for epistemic relativism from a philosophical perspective: underdetermination and (...) norm-circularity. His main negative result is that these arguments fall short of establishing epistemic relativism. -/- Despite arguing for epistemic absolutism, Seidel aims to provide an account of non-relative justification that nevertheless integrates the basic, correct intuition of the epistemic relativist. His main positive result is that the epistemic absolutist can very well accept the idea that people using different standards of justification can be equally justified in holding their beliefs: Rational disagreement, he maintains, is perfectly possible. -/- The book provides a detailed critique of relativism in the sociology of scientific knowledge and beyond. With its constructive part it aims at making conciliatory steps in a highly embittered discussion between sociology and philosophy of science. (shrink)

English summary: The focus of the contributions in this volume is on the relationships of the young Kierkegaard with the philosophy in Berlin and also with Pietism whose influence expresses itself mainly in his later edifying writings. Berlin and Halle are important reference points for Kierkegaard's roots of thinking which can be characterized as passion and inwardness. Texts about love from all periods of his work together with musical and visual reflections on Kierkegaard combine both aspects and provide an aesthetic (...) comment to the scholarly contributions in this volume. These contributions are the results of two German-Danish conferences in the Kierkegaard Year 2013 in Berlin and Halle, which were funded by the Danish Carlsberg Fond and the Centre for Theology and Theological Education of the Church of Denmark and were organized by the theological faculties in Berlin and Halle. German description: Zentral fur diesen spannenden Aufsatzband sind Beziehungen des jungen Kierkegaard zur Berliner Philosophie sowie sein Verhaltnis zum Pietismus in den erbaulichen Schriften vor allem des spaten Kierkegaard. Berlin und Halle sind wichtige Bezugspunkte fur die Wurzeln des Kierkegaardschen Denkens, die man gut mit den begriffen 'Leidenschaft' und 'Innerlichkeit' charakterisieren kann. Texte uber die Liebe aus allen Phasen des Kierkegaardschen Werkes mit musikalischen und visuellen Reflexionen zu Kierkegaard verbinden die beiden Aspekte miteinander und fungieren als ein asthetischer Kommentar zu den wissenschaftlichen Beitragen. Die Beitrage des Bandes gehen auf zwei deutsch-danische Tagungen im Kierkegaardjahr 2013 in Berlin und Halle zuruck, die vom danischen Carlsbergfond und dem Theologisch-Padagogischen Zentrum der danischen Volkskirche finanziert wurden und in Zusammenarbeit mit den theologischen Fakultaten in Berlin und Halle stattfanden.

Critics have charged that Heidegger's account of authenticity is morally nihilistic, that his fundamental ontology is either egocentric or chauvinistic; and many see Heidegger's turn to Nazism in 1933 as following logically from an indifference, and even hostility, to "otherness" in the premises of his early philosophy. In_ The Fragile "We": Ethical Implications of Heidegger's "Being and Time,"_ Lawrence Vogel presents three interpretations of authentic existence--the existentialist, the historicist, and the cosmopolitan--each of which is a plausible version of the (...) personal ideal depicted in _Being and Time._ He then draws parallels between these interpretations and three moments in the contemporary liberal-communitarian debate over the relationship of the "I" and the "We." His book contributes both to a diagnosis of what there is about _Being and Time_ that invites moral nihilism and to a sense of how fundamental ontology might be recast so that "the other" is accorded an appropriate place in an account of human existence.

The ArgumentContemporary natural sciences succeed remarkably well in ensuring a relatively continuous transmission of their cognitively relevant traditions and in creating a widely shared background consensus among their practitioners – hermeneutical ends seemingly achieved without hermeneutical awareness or explicitly acquired hermeneutical skills.It is a historically specific – emerging only in the nineteenth century – cultural organization of the Author-Text-Reader relation which endows them with such an ease of hermeneutical achievements: an institutionally fixed form of textual and intertextual practices, normatively posited (...) ways of adequate reception and criticism, etc. The same organization also explains a number of their often-discussed epistemic and cultural characteristics: their depersonalized objectivity, the social closure of their discourse and their reduced cultural significance, the shallow historical depth of their activated traditions, etc.The cognitive structure and the social function of contemporary natural sciences are intimately interwoven with a set of sui generis cultural relations that are partially fixed in the textual characteristics of their literary objectivations. A comparative hermeneutical analysis of natural sciences as a specifically constituted and institutionalized cultural genre or discourse-type brings into relief those contingent cultural conditions and relations to which some of their fundamental epistemological characteristics are bound, or at least with which they are historically closely associated.

The political scientist and former Bavarian Minister of Culture Hans Maier has created a historically profound, theologically educated, literarily and musically highly sensitive, politically mature body of work, with which he has inscribed himself in the (intellectual) history of the Federal Republic. This book is the first to contain contributions by renowned scholars and politicians on the rich work and impact of the Catholic scholar and politician Hans Maier. It thematises and appreciates in detail his view of German history and (...) the traditions of political thought, his critique of political language, political theology, totalitarianism and political religions, but also his contributions on Catholicism and modernity, his writings on literature and music, and finally his influence as an academic teacher, public intellectual and politician. With contributions by Udo Bermbach, Thomas Brose, Ahmet Cavuldak, Horst Dreier, Hermann-Josef Große Kracht, Jens Hacke, Oliver Hidalgo, Hans Günter Hockerts, Patrick Horst, Horst Möller, Heinrich Oberreuter, Henning Ottmann, Mark Edward Ruff, Hans Otto Seitschek, Michael Stolleis, Bernhard Vogel, Peter Graf von Kielmansegg, Theo Waigel and Markus Zimmermann.

In Western medicine the interpretation prevails that mental illness is a psychological and/or biological disorder. Most important concepts in health psychology, such as sense of coherence, self‐efficacy, hope, or dispositional optimism are all very cognition and individual centered. In this individualized perspective, mental illness is constructed in such a way that it can be treated in a dyadic doctor–patient or therapist–patient relationship with the help of drugs or therapeutic techniques. In this article, I would like to develop a contrasting social (...) construction of mental illness. In Umbanda and Candomblé temples in Brazil, what is interpreted in the Western model as illness is understood as a “spiritual problem.” Here, the individual is constructed in relationship to the community, and individual health and healing is footed in moral‐spiritual orders. In presenting the details of my investigation, I will apply Grawe’s common factors as a foil for developing the link between mental illness and its social context. (shrink)

Interpreters of Machiavelli easily agree that his political writings have profoundly influenced our fundamental ideas of state and society, yet these interpreters rarely agree on what Machiavelli really thought. Did Machiavelli seek to recover classical republicanism in the Aristotelian tradition, or did he aspire to usher in modernity? Was he a cynic who assumed human beings to be inescapably wicked and offered technical advice to tyrants, or did he aim at some version of "the good life"? Did he create a (...) general theory of politics, or did he teach us that political issues should be approached in a particular contextual, dialectical, or rhetorical manner? Through systematic analysis, Markus Fischer's cogent and articulate study succeeds in resolving these questions. Well-Ordered License will appeal both to new students of Machiavelli and to scholars who have long sought to reconcile the seeming incoherence of his work. (shrink)

Among the many “post”-isms, through which the thought of the present attempts both to create an orientation in regard to its historical place and possibilities, and simultaneously to express its frustration and anxiety about the lack of such an orientation, there is one—certainly predating all the others—which seems to enjoy, perhaps alone among them, a rather strong consensual acceptance. We live in post-metaphysical times, at the times of, or even after, the end of metaphysics. The relatively broad unanimity with respect (...) to this global description may, of course, be due to the fact that it seems to relate to some internal affair of philosophy—an activity which hardly commands a particularly great interest or respect today. Nevertheless such a consensus of philosophers over the state of philosophy seems to be a remarkable occurrence even in itself, given the ineliminable strife of its sects which characterizes its whole history.

Many commentators hold that in addition to the categorical imperative of morality, Kant also posits an objective law of non-moral practical rationality, 'the' Hypothetical Imperative. On this view, the appeal to the Hypothetical Imperative increases the dialectical options that Kantians have vis-a-vis Humean skepticism about the authority of reason, and it allows for a systematic explanation of the possibility of non-moral weakness of will. I argue that despite its appeal, this interpretation cannot be sustained: for Kant the only objective, universally (...) valid a priori principle of practical reason that governs transcendentally free agents is the moral law. All non-moral practical rules are mere “precepts” that lack genuine objectivity, certainty, and intersubjective validity. I suggest that for Kant the rejection of the possibility of non-moral practical laws plays an important part in his argument for the supreme rational authority of moral norms over prudential precepts of happiness.

Schelling entwirft in seiner Spätphilosophie einen neuen Philosophietypus, der in Konkurrenz zu Hegels Metaphysik tritt. Dabei greift er Hegel nicht nur auf dem Gebiet fundamentaler theoretischen Annahmen an, sondern sucht ihn insbesondere durch einen neuen Begriff von Religion zu überbieten. Die Arbeit untersucht dies im Ausgang von Schellings "Philosophie der Mythologie".

G. A. Cohen has argued that egalitarian justice proscribes equality-upsetting economic incentives, but that individuals nevertheless are required to make a sufficiently large productive contribution to society. This article argues, however, that Cohen’s claim that justice is insensitive to Pareto concerns and simply is equality, undermines such a duty. In fact, Cohen cannot say that justice prefers a distribution where everyone is equally well off to one where everyone is equally badly off. Individuals hence cannot have a duty of justice (...) to use their talents at a more productive level. This indifference risks removing Cohen’s egalitarianism’s appeal as an alternative to the Rawlsian position it challenges. Several ways of avoiding this problem are proposed and evaluated. Ultimately, it is argued that such a duty to contribute must instead be based on a concern for both equality and human flourishing. The ethos Cohen defends must hence be made pluralist, and encourage a commitment to both principles. (shrink)

The model-checking problem for a logic L on a class C of structures asks whether a given L-sentence holds in a given structure in C. In this paper, we give super-exponential lower bounds for fixed-parameter tractable model-checking problems for first-order and monadic second-order logic. We show that unless PTIME=NP, the model-checking problem for monadic second-order logic on finite words is not solvable in time f·p, for any elementary function f and any polynomial p. Here k denotes the size of the (...) input sentence and n the size of the input word. We establish a number of similar lower bounds for the model-checking problem for first-order logic, for example, on the class of all trees. (shrink)

In den letzten zehn Jahren sind die digitalen Geisteswissenschaften von einem Randphänomen zu einem der sichtbareren Felder kultur- und geisteswissenschaftlicher Forschung geworden. Dieser Erfolg ist von Kritik begleitet und Fotis Jannidis identifiziert drei Topoi der Kritik an den Digital Humanities, die oft vorgebracht und wiederholt werden: 1. ›Das wussten wir schon vorher‹ 2. ›Die Themen der Digital Humanities sind veraltet‹ 3. Es handle sich bei den Digital Humanities um eine neue Form des Positivismus, der geisteswissenschaftliche Gegenstände nicht adäquat beschreibt. Diese (...) drei Vorwürfe gegen die Digital Humanities werden von Jannidis aufgegriffen und auf ihren argumentativen und wissenschaftspolitischen Gehalt befragt und hinterfragt. Der Beitrag schließt mit einem Plädoyer für das Ausprobieren, Basteln und für die Neugierde auf die neu entstehenden Datensammlungen in den Bibliotheken und Archiven. Markus Krajewski hält die Erwartungen an das Innovationspotenzial der Digital Humanities dagegen für überzogen, die aus seiner Perspektive bisher über den Status einer Hilfswissenschaft nicht hinausgekommen sind. So wie die Diplomatik um die Analyse von Urkunden oder die Numismatik um die Einordnung von Münzen oder die Paläographie um die Analyse von Handschriften besorgt ist, so kümmern sich die Digital Humanities bisher lediglich um die Nahtstelle von geisteswissenschaftlichen Forschungsfragen mit computergestützten Methoden. Die eigentliche Aufgabe der Digital Humanities bestünde aber darin, die Kulturtechnik Codieren in den Vordergrund zu rücken. Denn Programmcodes lesen und schreiben zu können, seien auch für Geisteswissenschaftler eine Schlüsselkompetenz, damit die Schrift der Zukunft – die von Softwareentwicklern, Computeringenieuren und selbstlernenden Maschinen entworfenen Algorithmen – weiterhin kritisch kommentiert und interpretiert (und nicht bloß passiv angewandt) werden kann. During the last ten years, the so-called digital humanities have developed from a footnote to being a major player in the academic field of cultural studies and humanities alike. However, success goes hand in hand with increasing criticism, and Fotis Jannidis identifies three topoi of critique digital humanities repeatedly have to face. 1. ›We already knew that‹ 2. ›The topics of digital humanities are outdated‹ 3. Digital humanities are said to be a new form of positivism not adequately describing humanities related issues. Jannides takes up these accusations against digital humanities by scrutinizing and questioning their argumentative and scientific- political substance. The article closes with a speech promoting of a phase of trial and error, of tinkering and of curiosity for the subject at hand while analyzing newly originated data collections from libraries or archives. In Markus Krajewski’s opinion, however, the expectations placed in the potential of innovation of digital humanities are exaggerated which subsequently leads him to label them an ancillary discipline. The usefulness of digital humanities is entirely limited to providing the link between humanities-related research questions and computer-based methods in the same way diplomatics relies on the analysis of records, numismatics on the process of categorizing coins or paleography on the analysis of historical manuscripts. Krajewski sees the real task of digital humanities in bringing the cultural technology of coding into the spotlight. He describes the ability to write and read source code as a key competence every modern humanities scholar needs in order to be able to critically comment and interpret the script of the future: algorithms designed by software developers, computer engineers, and auto-didactic machines.

Many philosophers of science think that most laws of nature (even those of fundamental physics) are so called ceteris paribus laws, i.e. roughly speaking, laws with exceptions. Yet, the ceteris paribus clause of these laws is problematic. Amongst the more infamous difficulties is the danger that ‘For all x: Fx then Gx, ceteris paribus’ may state no more than a tautology: ‘For all x: Fx then Gx, unless not’. One of the major attempts to avoid this problem (and others concerning (...) ceteris paribus laws) is to claim that the subject matter of laws are ascriptions of dispositions, powers, capacities etc., and not the regular behaviour we find in nature. That we do not know whether the cetera are paria in a specific situation does not matter to the dispositionalist because the objects have the disposition regardless of the circumstances. The defence of the latter claim is that dispositions can be instantiated without being manifested. Hence, the laws that ascribe dispositions are strict and it looks as if they do not face the above mentioned problems of ceteris paribus laws. In this chapter I attempt to show that these assumptions are wrong. I hope to illustrate that not only does the ceteris paribus clause reoccur inside the dispositions, moreover, there are laws – laws about non-fundamental entities with instable dispositions – which bear a ceteris paribus clause that cannot be hidden in a disposition.

In “How Art Teaches: A Lesson from Goodman”, Markus Lammenranta inquires if and how artworks can convey propositional knowledge about the world. Lammenranta argues that the cognitive role of art can be explained by revising Nelson Goodman’s theory of symbols. According to Lammenranta, the problem of Goodman’s theory is that, despite providing an account of art’s symbolic function, it denies art the possibility of mediating propositional knowledge. Lammenranta claims that Goodman’s theory can be augmented by enlarging it with an (...) account of direct reference developed by Bertrand Russell and contemporary philosophy of language. On this basis, an expanded version of Goodman’s theory can explain how artworks can express propositions even without being linguistic, representational, or non-fictive. Lammenranta explicates his theory by explaining how abstract paintings and literary fictions can mediate propositional claims about the actual, everyday world. (shrink)

Die Fachdidaktik der Philosophie und Ethik fordert Problemorientierung und Lebensweltbezug. Exkursionen, außerschulische Lernorte oder ‚Outdoor Education‘ haben allerdings bisher kaum Berücksichtigung in der fachdidaktischen Forschung erfahren. Eine systematische Auslotung von möglichen Kooperationen, Synergieeffekten oder Unvereinbarkeiten wurde bisher nicht geleistet. Der vorliegende Band versucht diese Lücke zu schließen und eine erste Grundlage für weiterführende Forschungen, Erprobungen und Diskussionen zu schaffen. Er soll damit sowohl einen Beitrag zur Lehrerausbildung an Universitäten und Studienseminaren als auch für die fachdidaktische Explorationsforschung leisten.

"Das Buch ist gut zu lesen und als Urlaubslektüre zu empfehlen." (Sachverhalte 3/2015) "Der klare und sachlogisch überzeugende Argumentationsgang des vorliegenden Bands macht ihn, in Kombination mit einer sehr gelungenen, sprachlichen Gestaltung zu einem echten Lesevergnügen und kann für philosophische 'Einsteiger' zum Beginn einer philosophischen Liebesgeschichte werden. Für Lehrende der Philosophie an Schule und Hochschule ist Tiedemanns Band (…) Fundgrube sowie fachlich fundierter und didaktisch ausgezeichnet aufbereiteter Begleiter durch Unterricht und Seminar." (Mathias Balliet, ZDPE 1/2015) Liebe, Sexualität und Freundschaft gehören (...) nicht nur zu den intensivsten Erfahrungen des Menschen, sie werfen auch zahlreiche Fragen auf: Wie wichtig sind sie für ein gelungenes Leben? Wie genau unterscheiden sich Liebe und Freundschaft? Ist Sexualität ein eigenständiges Phänomen oder notwendig mit Liebe verbunden? Besteht Liebe eher aus selbstloser Fürsorge oder aus eigennütziger Habsucht? Von der Antike bis zur Gegenwart haben sich namhafte Denker von Sokrates über Rousseau bis hin zu Sigmund Freud und Simone de Beauvoir dieser Fragen angenommen und dabei erstaunliche Antworten formuliert. Die Philosophie der Liebe ist so vielgestaltig wie ihr Gegenstand. Ist platonische Liebe wirklich lustfeindlich und entsagungsvoll? Beruht die christliche Sexualmoral auf einem Mutterkomplex? Muss man dichten können wie Goethe, um mit Schiller befreundet zu sein? Ist alle Liebe so egoistisch, wie Schopenhauer uns einreden will, oder sind wahre Liebe und Freundschaft vielleicht doch für jeden von uns möglich? Das Buch bietet einen abwechslungsreichen Streifzug durch die Antworten der Ideengeschichte und lädt ein zum Weiterdenken. Love, sexuality and friendship are not only among the most intense of human experiences, they also give rise to many questions: How important are they for a successful life? How exactly do love and friendship differ? Is sexuality an independent phenomenon or does it have to be connected with love? Is love more a matter of selfless care or of selfish desire? From antiquity to the present day prominent thinkers from Socrates through Rousseau to Sigmund Freud and Simone de Beauvoir have taken on these questions and come up with surprising answers. The philosophy of love is as varied as love itself. Is Platonic love really opposed to pleasure and obsessed with self-denial? Is Christian sexual morality based on a mother-complex? Is it necessary to write like Goethe to be friends with Schiller? Is all love as egotistical as Schopenhauer would have us believe, or are true love and friendship still possible for all of us? This book takes us on a diverse foray into the answers offered by intellectual history and invites us to think further for ourselves. (shrink)

Speaking of truth inescapably confronts us with paradoxes, i.e., correct deductive propositions like a Cretan claiming that all Cretans lie which (due to negative systemic self-reference) end up as circular contradictions, indeterminable questions, or dilemmas. Faced with the numerous paradoxical statements (apparently 82) found in the Bible, the German Protestant reformer Sebastian Franck (14991542), for example, conceded that any truth of God cannot be found in language but only in the immediate silent experience of God. Likewise, believers in an uncompromising (...) search for true facts about this world would certainly agree with (though arguably misappropriate) Wittgenstein in claiming that Whereof one cannot speak, thereof one must be silent. Paradoxes this article claims must neither be feared, nor avoided, nor become subject to hopeless attempts in searching for logic solutions. Paradoxes lead the way to truth in demonstrating that questions of truth, or truth claims, cannot be adequately addressed within the same system of communication (ortho-system) in which they are raised. The encounter with paradoxes (e.g., a God who creates but is uncreated) elevates language and communication onto a meta-level (or system) of communication in which new means (like for instance Gdel's numbering) are needed to speak of what is real but apparently cannot be true. These means, however, will turn out to be likewise paradoxes that furthermore call for new and creative ways of speaking of such truths that previously could not be communicated. The creative admission of paradoxes into communication philosophy will not solve age-old problems or dilemmas; however, it will playfully open up the conversation of science with religion to the creative means of the arts were truth is not argued but performed in paradoxes.
