    Abstract
    This volume has the virtue of airing a number of refreshing voices that are not often heard on this side of the Atlantic, and that bring perspectives that should energize our conversations about information in living systems." --Evelyn Fox Keller, MIT "Terzis and Arp have brought together an international array of experimental and theoretical scientists, philosophers, and cognitive scientists to explore the most consequential notion in modern biology--information. The notion is indispensable to molecular biology, and yet we have no idea how seriously we need to take it in that domain. The role of information is equally central to the origin and maintenance of life in a Second Law-driven world that destroys order. And the naturalization of information is the only bridge that can be crossed from cognitive psychology to neuroscience. All of these issues are faced squarely and accessibly in this important volume." --Alex Rosenberg, Duke University "Since the 1960s at least, it has become clear that we cannot content ourselves with describing living systems, and their life cycles, only in terms of matter and energy. An additional dimension--information--is the necessary complement. However, following an initial enthusiasm for an information-based approach to biology, conceptual developments and practical applications have been slow, to such an extent that doubts have eventually arisen, among biologists and philosophers alike, as to the real relevance, if not the legitimacy, of this approach. How profoundly ill-advised were those concerns is dramatically demonstrated by this excellent collection. Information and Living Systems provides a convincing and healthily fresh overview of this subject area in many of its ramifications, throughout the whole of biology." --Alessandro Minelli, University of Padova "Since the time of the discovery of the double-helical structure of DNA and its expression, scientists and philosophers have become increasingly aware that information is integral to the understanding of the organization of life--indeed, to the understanding of life. Information and Living Systems covers the gamut of issues--from the properties of the organism itself to epigenetic and evolutionary considerations to cognition, language, and personality. It transcends in scope and depth any available publications on bioinformation known to me. It is an important scholarly contribution that will interest professional biologists, philosophers, and information theorists, and will be very useful in courses for advanced undergraduate and graduate students.

    Abstract
    Luciano Floridi's 1999 monograph, Philosophy and Computing: An Introduction, provided the impetus for the theme of this issue, more for what it did not say about librarianship and information studies (LIS) than otherwise. Following the pioneering works of Wilson, Nitecki, Buckland, and Capurro (plus many of the authors of this issue), researchers in LIS have increasingly turned to the efficacy of philosophical discourse in probing the more fundamental aspects of our theories, including those involving the information concept. A foundational approach to the nature of information, however, has not been realized, either in partial or accomplished steps, nor even as an agreed, theoretical research objective. It is puzzling that while librarianship, in the most expansive sense of all LIS-related professions, past and present, at its best sustains a climate of thought, both comprehensive and nonexclusive, information itself as the subject of study has defied our abilities to generalize and synthesize effectively. Perhaps during periods of reassessment and justification for library services, as well as in times of curricular review and continuing scholarly evaluation of perceived information demand, the necessity for every single stated position to be clarified appears to be exaggerated. Despite this, the important question does keep surfacing as to how information relates to who we are and what we do in LIS.

    For decades, we have been told we live in the "information age"-a time when disruptive technological advancement has reshaped the categories and social uses of knowledge and when quantitative assessment is increasingly privileged. Such methodologies and concepts of information are usually considered the provenance of the natural and social sciences, which present them as politically and philosophically neutral. Yet the humanities should and do play an important role in interpreting and critiquing the historical, cultural, and conceptual nature of information. This book is one of two companion volumes that explore theories and histories of information from a humanistic perspective. They consider information as a long-standing feature of social, cultural, and conceptual management, a matter of social practice, and a fundamental challenge for the humanities today. Information: A Reader provides an introduction to the concept of information in historical, literary, and cultural studies. It features excerpts from more than forty texts by theorists and critics who have helped establish the notion of the "information age" or expand upon it. The reader establishes a canonical framework for thinking about information in humanistic terms. Together with Information: Keywords, it sets forth a major humanistic vision of the concept of information.

    Abstract
    For several decades Rafael Capurro has been at the forefront of defining the relationship between information and modernity through both phenomenological and ethical formulations. In exploring both of these themes Capurro has re-vivified the transcultural and intercultural expressions of how we bring an understanding of information to bear on scientific knowledge production and intermediation. Capurro has long stressed the need to look deeply into how we contextualize the information problems that scientific society creates for us and to re-incorporate a pragmatic dimension into our response that provides a balance to the cognitive turn in information science. With contributions from 35 scholars from 15 countries, Information Cultures in the Digital Age focuses on the culture and philosophy of information, information ethics, the relationship of information to message, the historic and semiotic understanding of information, the relationship of information to power and the future of information education. This Festschrift seeks to celebrate Rafael Capurro's important contribution to a global dialogue on how information conceptualization, use and technology impact human culture and the ethical questions that arise from this dynamic relationship.

    Abstract
    This book addresses some of the key questions that scientists have been asking themselves for centuries: what is knowledge? What is information? How do we know that we know something? How do we construct meaning from the perceptions of things? Although no consensus exists on a common definition of the concepts of information and communication, few can reject the hypothesis that information - whether perceived as « object » or as « process » - is a pre-condition for knowledge. Epistemology is the study of how we know things (anglophone meaning) or the study of how scientific knowledge is arrived at and validated (francophone conception). To adopt an epistemological stance is to commit oneself to render an account of what constitutes knowledge or in procedural terms, to render an account of when one can claim to know something. An epistemological theory imposes constraints on the interpretation of human cognitive interaction with the world. It goes without saying that different epistemological theories will have more or less restrictive criteria to distinguish what constitutes knowledge from what is not. If information is a pre-condition for knowledge acquisition, giving an account of how knowledge is acquired should impact our comprehension of information and communication as concepts. While a lot has been written on the definition of these concepts, less research has attempted to establish explicit links between differing theoretical conceptions of these concepts and the underlying epistemological stances. This is what this volume attempts to do. It offers a multidisciplinary exploration of information and communication as perceived in different disciplines and how those perceptions affect theories of knowledge.

    Rez. in: Spektrum der Wissenschaft. 2004, H.11., S.92-96 (S. Stier): "Nach Einsteins Allgemeiner Relativitätstheorie gibt es im Kosmos Objekte von so ungeheurer Gravitationskraft, dass aus ihrem Inneren keinerlei Informationen, auch nicht in Form von Licht, nach außen dringen können; sie werden deshalb als Schwarze Löcher bezeichnet. Eines der vielen Rätsel, die sie umgeben, war lange Zeit die Größe ihrer Entropie (siehe »Das holografische Universum« von Jacob Bekenstein, Spektrum der Wissenschaft 11/ 2003, S. 34). Nach der herkömmlichen Definition ist die Entropie ein Maß für den Informationsgehalt eines Objekts; sie berechnet sich aus der Zahl seiner inneren Zustände, in denen es dieselben Eigenschaften hat. Damit hängt sie davon ab, welche Eigenschaften man zur Beschreibung des Objekts wählt und wie detailliert man seine inneren Zustände beschreibt. Entropie und Information sind also relative, vom Kontext einer bestimmten Beschreibung abhängige Maße. je detaillierter die Beschreibung seiner inneren Zustände, desto größer die Entropie. Nicht so bei einem Schwarzen Loch: Da es alle Informationen über sein Inneres verbirgt, ist seine Entropie die Obergrenze für alles, was man überhaupt darüber wissen könnte, unabhängig von irgendwelchen Modellen seiner Struktur. Information wird damit zu einer unabhängigen Eigenschaft eines Objekts und zu einer absoluten physikalischen Größe. Das ist ein radikaler Bruch im Verständnis von Information. Mit Hilfe der von Bekenstein vor dreißig Jahren angegebenen Formel kann man berechnen, wie die Entropie eines Schwarzen Lochs von der Größe unseres Universums dadurch zunimmt, dass von außen ein Proton hineinstürzt. Diese Änderung lässt sich als der Informationsgehalt des Protons selbst interpretieren: Es sind 10**40 Bit, ein Wert, der im Rahmen der etablierten Physik eigentlich nicht erklärbar ist.
    Während sich die Beiträge zur Urtheorie an Spezialisten wenden, finden sich zu anderen Arbeitsgebieten von Weizsäckers eher allgemeinverständliche Darstellungen: Astro- und Kernphysik mit den thermonuklearen Prozessen in Sternen und der Entstehung der Planetensysteme sowie die Philosophie der Naturwissenschaft und der Zeit - alles in der für solche Festschriften typischen bunten Mischung. Hervorgehoben sei die Darstellung des Hamburger Friedensforschers Götz Neuneck zur deutschen Atomforschung während des Zweiten Weltkriegs und zu den nachfolgenden Bemühungen internationaler Wissenschaftler, die Institution des Kriegs nach dem Bau der Atombombe abzuschaffen. In beiden hat von Weizsäcker eine herausragende Rolle gespielt. Ein wichtiges Thema des Buchs sind die Grundlagen der Quantentheorie. Mit der Charakterisierung von Objekten durch Information ist die Urtheorie eine radikale Weiterführung der »Kopenhagener Deutung«, jener orthodoxen, aber von vielen Physikern nur mangels einer überzeugenden Alternative akzeptierten Interpretation der Quantentheorie. Ein seit deren Anfängen andauernder Streit geht darum, ob die Wellenfunktion, die Wahrscheinlichkeiten für Messergebnisse vorhersagt, gemäß der Kopenhagener Deutung das mögliche Wissen eines Beobachters darstellt oder eine davon unabhängige Realität beschreibt. Wie lebendig diese Debatte ist, machen mehrere Beiträge in diesem Buch deutlich. Hans Primas und Harald Atmanspacher lösen den Widerspruch nach dem Muster des Teilchen-Welle-Dualismus auf Beide Positionen beruhen auf unterschiedlichen Auffassungen der Wirklichkeit, die beide für eine Beschreibung der Natur je nach der zu Grunde liegenden Fragestellung notwendig seien. Claus Kiefer erläutert das Phänomen der »Dekohärenz«, wonach der quantenmechanische Messprozess in neuem Licht erscheine, wenn auch die Kopplung des Messgeräts an seine Umgebung berücksichtigt werde, denn unrealistische Überlagerungszustände im Messprozess wie die berühmte sowohl tote als auch lebendige »Schrödinger'sche Katze« seien bereits durch die Quantenmechanik selbst ausgeschlossen. Spätestens wenn der Kosmos als Ganzes betrachtet werde, komme die Kopenhagener Deutung an ihr Ende, denn hier gebe es keinen Beobachter mehr, für den die quantentheoretischen Möglichkeiten zu Fakten werden könnten.
    Einen interessanten Vorschlag machen schließlich Ceslav Brukner und Anton Zeilinger von der Universität Wien. Ganz in von Weizsäckers Sinn, die Naturwissenschaft auf Ja-Nein-Aussagen zurückzuführen, streben sie nach einer Herleitung der Quantentheorie aus der Informationstheorie. Ihr Ausgangspunkt ist die Annahme, dass jedes physikalische Objekt einen endlichen Informationsgehalt hat. Da diese Information aber nicht ausreiche, um die Resultate aus allen möglichen Messungen festzulegen, könne eine bestimmte Messung nicht mehr mit Sicherheit vorhergesagt werden. Der Indeterminismus der Quantentheorie ist damit auf ein fundamentaleres Prinzip zurückgeführt. Viele Autoren heben die Bedeutung von Weizsäckers Fragen und Antworten als Quelle der Inspiration und als Herausforderung an die etablierte Wissen schaft hervor, die in ihrer Vorausschau noch nicht an ihr Ende gekommen sei. Dem ist wenig hinzuzufügen."
