Manfred Eigen extended Erwin Schroedinger’s concept of “life is physics and chemistry” through the introduction of information theory and cybernetic systems theory into “life is physics and chemistry and information.” Based on this assumption, Eigen developed the concepts of quasispecies and hypercycles, which have been dominant in molecular biology and virology ever since. He insisted that the genetic code is not just used metaphorically: it represents a real natural language.However, the basics of scientific knowledge changed dramatically within the second half (...) of the 20th century.Unfortunately, Eigen ignored the results of the philosophy of science discourse on essential features of natural languages and codes: a natural language or code emerges from populations of living agents that communicate. This contribution will look at some of the highlights of this historical development and the results relevant for biological theories about life. (shrink)

The Serial Endosymbiotic Theory explains the origin of nucleated eukaryotic cells by a merging of archaebacterial and eubacterial cells. The paradigmatic change is that the driving force behind evolution is not ramification but merging. Lynn Margulis describes the symbiogenetic processes in the language of mechanistic biology in such terms as “merging”, “fusion”, and “incorporation”. Biosemiotics argues that all cell-cell interactions are (rule-governed) sign-mediated interactions, i.e., communication processes. As the description of plant communication demonstrates, the biosemiotic approach is not limited to (...) the level of molecular biology, but is also helpful in examining all sign-mediated interactions between organisms on the phenotypic level. If biosemiotics also uses the notions of “language” and “communication” to describe non-human sign-mediated interactions, then the underlying scientific justification of such usage should be critically considered. Therefore, I summarize the history of this discussion held between 1920 and 1980 and present its result, the pragmatic turn. (shrink)

This contribution demonstrates that the development and growth of plants depends on the success of complex communication processes. These communication processes are primarily sign-mediated interactions and are not simply an mechanical exchange of ‘information’, as that term has come to be understood (or misunderstood) in science. Rather, such interactions as I will be describing here involve the active coordination and organisation of a great variety of different behavioural patterns — all of which must be mediated by signs. Thus proposed, a (...) biosemiotics of plant communication investigates communicationprocesses both within and among the cells, tissues, and organs of plants as sign-mediated interactions which follow (1) combinatorial (syntactic), (2) context-sensitive (pragmatic) and (3) content-specific (semantic) levels of rules. As will be seen in the cases under investigation, the context of interactionsin which a plant organism is interwoven determines the content arrangement of its response behaviour. And as exemplified by the multiply semiotic roles playedby the plant hormone auxin that I will discuss below, this means that a molecule type of identical chemical structure may function in the instantiation of differentmeanings (semantics) that are determined by the different contexts (pragmatics) in which this sign is used.

“DNA-RNA-Protein-everything else” (Arthur Kornberg) on its detail, satisfactory answers to central questions – What is life? head and who try to understand protein bodies as context- How did it originate and how do we view ourselves as living dependent interpreters of the genetic text, (3.) a philosophy that beings? – have been lost in a universe of analytical units.

It is becoming increasingly evident that the driving forces of evolutionary novelty are not randomly derived chance mutations of the genetic text, but a precise genome editing by omnipresent viral agents. These competences integrate the whole toolbox of natural genetic engineering, replication, transcription, translation, genomic imprinting, genomic creativity, enzymatic inventions and all types of genetic repair patterns. Even the non-coding, repetitive DNA sequences which were interpreted as being ancient remnants of former evolutionary stages are now recognized as being of viral (...) descent and crucial for higher-order regulatory and constitutional functions of protein structural vocabulary. In this article I argue that non-randomly derived natural genome editing can be envisioned as (a) combinatorial (syntactic), (b) context-specific (pragmatic) and (c) content-sensitive (semantic) competences of viral agents. These three-leveled biosemiotic competences could explain the emergence of complex new phenotypes in single evolutionary events. After short descriptions of the non-coding regulatory networks, major viral life strategies and pre-cellular viral life three of the major steps in evolution serve as examples: There is growing evidence that natural genome-editing competences of viruses are essential (1) for the evolution of the eukaryotic nucleus, (2) the adaptive immune system and (3) the placental mammals.

Manfred Eigen employs the terms language and communication to explain key recombination processes of DNA as well as to explain the self-organization of human language and communication: Life processes as well as language and communication processes are governed by the logic of a molecular syntax, which is the exact depiction of a principally formalizable reality.

Organisms that share the capability of storing information about experiences in the past have an actively generated background resource on which they can compare and evaluate more recent experiences in order to quickly or even better react than in previous situations. This is an essential competence for all reaction and adaptation purposes of living organisms. Such memory/learning skills can be found from akaryotes up to unicellular eukaryotes, fungi, animals and plants, although until recently, it had been mentioned only as a (...) capability of higher animals. With the rise of epigenetics, the context-dependent marking of experiences at both the phenotype and the genotype level is an essential perspective to understand memory and learning in all organisms. Both memory and learning depend on a variety of successful communication processes within the whole organism. (shrink)

Should decision-making algorithms be held to higher standards of transparency than human beings? The way we answer this question directly impacts what we demand from explainable algorithms, how we govern them via regulatory proposals, and how explainable algorithms may help resolve the social problems associated with decision making supported by artificial intelligence. Some argue that algorithms and humans should be held to the same standards of transparency and that a double standard of transparency is hardly justified. We give two arguments (...) to the contrary and specify two kinds of situations for which higher standards of transparency are required from algorithmic decisions as compared to humans. Our arguments have direct implications on the demands from explainable algorithms in decision-making contexts such as automated transportation. (shrink)

This is the first coherent description of all levels of communication of ciliates. Ciliates are highly sensitive organisms that actively compete for environmental resources. They assess their surroundings, estimate how much energy they need for particular goals, and then realise the optimum variant. They take measures to control certain environmental resources. They perceive themselves and can distinguish between ‘self’ and ‘non-self’. They process and evaluate information and then modify their behaviour accordingly. These highly diverse competences show us that this is (...) possible owing to sign-mediated communication processes within ciliates, between the same, related and different ciliate species, and between ciliates and non-ciliate organisms. This is crucial in coordinating growth and development, shape and dynamics. This book further serves as a learning tool for research aspects in biocommunication in ciliates. It will guide scientists in further investigations on ciliate behavior, how they mediate signaling processes between themselves and the environment. (shrink)

Archaea represent a third domain of life with unique properties not found in the other domains. Archaea actively compete for environmental resources. They perceive themselves and can distinguish between 'self' and 'non-self'. They process and evaluate available information and then modify their behaviour accordingly. They assess their surroundings, estimate how much energy they need for particular goals, and then realize the optimum variant. These highly diverse competences show us that this is possible owing to sign- mediated communication processes within archaeal (...) cells, between the same, related and different archaeal species, and between archaea and non-archaeal organisms. This is crucial in coordinating growth and development, shape and dynamics. Such communication must function both on the local level and between widely separated colony parts. This allows archaea to coordinate appropriate response behaviors in a differentiated manner to their current developmental status and physiological influences. This book will orientate further investigations on how archaeal ecosphere inhabitants communicate with each other to coordinate their behavioral patterns and whats the role of viruses in this highly dynamic interactional networks.

Fungi are sessile, highly sensitive organisms that actively compete for environmental resources both above and below the ground. They assess their surroundings, estimate how much energy they need for particular goals, and then realise the optimum variant. They take measures to control certain environmental resources. They perceive themselves and can distinguish between ‘self’ and ‘non-self’. They process and evaluate information and then modify their behaviour accordingly. These highly diverse competences show us that this is possible owing to sign-mediated communication processes (...) within fungal cells, between the same, related and different fungal species, and between fungi and non-fungal organisms. Intraorganismic communication involves sign-mediated interactions within cells and between cells. This is crucial in coordinating growth and development, shape and dynamics. Such communication must function both on the local level and between widely separated mycelium parts. This allows fungi to coordinate appropriate response behaviors in a differentiated manner to their current developmental status and physiological influences. (shrink)

We put forth an account for when to believe causal and evidential conditionals. The basic idea is to embed a causal model in an agent’s belief state. For the evaluation of conditionals seems to be relative to beliefs about both particular facts and causal relations. Unlike other attempts using causal models, we show that ours can account rather well not only for various causal but also evidential conditionals.

We propose a method of learning indicative conditional information. An agent learns conditional information by Jeffrey imaging on the minimally informative proposition expressed by a Stalnaker conditional. We show that the predictions of the proposed method align with the intuitions in Douven, 239–263 2012)’s benchmark examples. Jeffrey imaging on Stalnaker conditionals can also capture the learning of uncertain conditional information, which we illustrate by generating predictions for the Judy Benjamin Problem.

"In der Philosophie der Gegenwart fehlt es an einem systematischen Lehrbuche uber die verwickelten Strukturverhaltnisse, die unseren alltaglichen und wissenschaftlichen Wirklichkeitsbegriffen zu Grunde liegen. Das vorliegende Buch versucht, diese Lucke auszufullen. Dem umfassenden Feld seiner Aufgabe entsprechend wendet es sich nicht nur an den engeren Kreis der Fachphilosophen, sondern zugleich an den weiteren Kreis aller derjenigen, denen der Wirklichkeitsbegriff ihres Arbeitsgebietes ein Problem ist." "(Aus dem Vorwort zu Band I)" Der Greifswalder Philosophieprofessor Gunther Jacoby (1889-1969) gilt neben Nicolai Hartmann (...) als Begrunder einer neuen, beschreibendenden Ontologie, die zu Beginn dieses Jahrhunderts als Gegenbewegung zum Neukantianismus entstand und die in ihren Raum- und Zeitanalysen die Ergebnisse der Relativitatstheorie Albert Einsteins verarbeitete. Jacobys Hauptwerk "Allgemeine Ontologie der Wirklichkeit" (der erste Band erschien 1925, der zweite Band in 2 Teilen 1955), das seit langerem vergriffen ist, wird jetzt als Reprint wieder aufgelegt, erganzt durch eine Einleitung und ein Verzeichnis seiner Publikationen.".

Wie Teile so zu einem Ganzen zusammengefügt werden, dass daraus schliesslich eine Übersummativität resultiert: Das Ganze mehr ist als die Summe seiner Teile. Die Überlegungen zur Produktivität der menschlichen Wahrnehmung sind Ausgangspunkt für Fragen der Ästhetik. (...) Warum empfinden wir Dinge als schön? Was ist das Besondere an der Wahrnehmung von Kunstwerken? Auf den ersten Blick könnte der Gegensatz zwischen dem wissenschaftlichen Text und den künstlerischen Arbeiten grösser nicht sein: Lesen versus Betrachten, Reflexion versus Anschauung. Text und Bilder bleiben autonom. Gemeinsam ist ihnen die Konzentration auf das Sehen als grundlegenden Erkenntnisakt. (shrink)

Pannenberg war nach eigenem Bekunden kein Hegelianer. Doch gibt es bemerkenswerte strukturelle und inhaltliche Parallelen zwischen seiner 'Anthropologie in theologischer Perspektive' und Hegels 'Philosophie des sujektiven Geistes', deren Wahrnehmung für eine aktuelle Lehre vom Menschen in hohem Masse bedeutsam sein kann.

Between 1650 and 1664, a giant globe was created in Gottorf under Duke Friedrich III, which was widely known and marvelled at by many contemporaries as a wonder of the world. The scientific management of the project was the responsibility of the court mathematician and librarian Adam Olearius. The Gottorf Globe and its counterpart (a “Sphaera Copernicana”) presented the astronomical knowledge of the time in a pictorial form. The image of the earth and the cosmos was also intended to show (...) the Creator and his omnipotence. Erhard Weigel, professor of mathematics at the University of Jena from 1653, also constructed monumental globes. These baroque world models, as well as Robert Long’s 18th-century sphere, can be considered the precursors of today’s planetariums. (shrink)

Bringing together leading figures in the study of international relations, this collection explores praxis as a perspective on international politics and law. It builds on the transdisciplinary work of Friedrich Kratochwil to reveal the scope, limits and blind spots of praxis theorizing.

A renaissance of virus research is taking centre stage in biology. Empirical data from the last decade indicate the important roles of viruses, both in the evolution of all life and as symbionts of host organisms. There is increasing evidence that all cellular life is colonized by exogenous and/or endogenous viruses in a non-lytic but persistent lifestyle. Viruses and viral parts form the most numerous genetic matter on this planet.

Every coordination within or between animals depends on communication processes. Although the signaling molecules, vocal and tactile signs, gestures and its combinations differ throughout all species according their evolutionary origins and variety of adaptation processes, certain levels of biocommunication can be found in all animal species: Abiotic environmental indices such as temperature, light, water, etc. that affect the local ecosphere of an organism and are sensed, interpreted. Trans-specific communication with non-related organisms. Species-specific communication between same or related species. Intraorganismic communication, (...) i.e., sign-mediated coordination within the body of the organism. This book gives an overview of the manifold levels of animal communication exemplified by a variety of species and thereby broadens the understanding of these organisms. (shrink)

Communication is defined as an interaction between at least two living agents which share a repertoire of signs. These are combined according to syntactic, semantic and context dependent, pragmatic rules in order to coordinate behavior. This volume deals with the important roles of soil bacteria in parasitic and symbiotic interactions with viruses, plants, animals and fungi. Starting with a general overview of the key levels of communication between bacteria, further reviews examine the various aspects of intracellular as well as intercellular (...) biocommunication between soil microorganisms. Th is includes the various levels of biocommunication between phages and bacteria, between soil algae and bacteria, and between bacteria, fungi and plants in the rhizosphere, the role of plasmids and transposons, horizontal gene transfer, quorum sensing and quorum quenching, bacterial-host cohabitation, phage-mediated genetic exchange and soil viral ecology.
