INTRODUCTION TO THE FIRST EDITION

Introduction to the first edi- tion

“Concepts lead us to make investigations; are the expression of our interest, and direct our interest.” Ludwig WITGENSTEIN, Philosophise Untersuchungen

“Information is a difference which makes a difference.” Gregory BATESON, Steps to an ecology of mind

Terms included in this glossary recap some of the main concepts, theories, problems and metaphors concern- ing INFORMATION in all spheres of knowledge. This is the first edition of an ambitious enterprise cov- ering at its completion all relevant notions relating to INFORMATION in any scientific context. As such, this glossariumBITri is part of the broader project Ramon Llull´s tree of science BITrum, which is committed to the mutual under- standing of all disciplines devoted to information across fields of knowledge and practice. This glossary pretends to make explicit the conflicts and agreements among use and meaning of terms related to information phenomena. Information is approached from opposing para- digms and also from competing and cooperating disciplines. Both in science and in ordinary life, conceptual, ethical, technical and societal problems regard information in an essential way. This glossary does not endorse or presuppose any paradigm or any theory, but rather locates into a public, explicit and commonly understandable space some of the crucial assumptions dividing informational concepts, theories, problems and metaphors. Moreover, we purport to embrace all distinct paradigms with a critical and comprehensive attitude. The glossary is the result of an original methodology, which places any entrance under the re- sponsibility of its editor. Authors possibly distinct from the editor contribute to different articles with texts, comments or discussions. Since authors come from many distinct fields of knowledge, each article should reflect many perspectival but rigorous approaches.

v METHODOLOGICAL NOTES INTRODUCTION TO THE FIRST EDITION

The glossary is an open work: the number and contents of all its entrances are updated and submitted to revision by editors and authors. For this reason, this first edition is only a first step in the active development of this collaborative methodology. Any interested reader wishing to contribute, may contact the general editors. This glossary is most indebted to the enthusiasm and work of José María Díaz Nafría. The editorial team, authors and correctors thank the Universidad de León and Caja España for their support to this initiative.

vi glossariumBITri INTRODUCTION TO THE PRESENT EDITION

Introduction to the present edition

“There have always been thinkers to believe that the fields of human knowledge betrays a fundamental unity. In modern times people ready to discuss this unity have come under grave suspicion. Surely, the crit- ics argue, no man is so presumptuous as to imagine that he can comprehend more than a tiny fraction of the scope of contemporary science. [...] And yet there are still men prepared to pursue the path of unity, and to discuss problems in an inter-disciplinary fashion: that is, without regard to the specialised viewpoint of any one branch of science.” Stafford BEER (Cybernetics and Manage- ment, 1959)

Four years after appearing the first book edition of the glossariumBITri (gB), it faces now a new phase of development, in which this new book version represents a milestone. The first devel- opment phase, 2008-2010, was clearly marked by an intensive cooperative work to stand up the clarification enterprise in which the gB is embarked on. Right after such phase, the gB was nurtured through valuable inputs covering essential aspects as , computation, com- plexity, etc., by distinguished researchers who have certainly enriched not only this book but the working team who is now before a more ambitious horizon. Besides some improvements in previous articles, the most important additions to the previous edition, incorporated herewith, corresponds to the articles developed in the areas of algorithmic theory, complexity theory, General Theory of Information and Cybersemiotics that we heartily thank to the cherished contributions of Mark Burgin and Søren Brier. Nevertheless, the flesh of the glossariumBITri has been enriched as well through entries, which do not show up in this book since they are still under review or discussion, but they surely will in the next edition. They are, of course, available in the interactive-gB. For this dressing up the naked bones of the gB, we warmly thank the contributions provided by Balu Athreya, Igor Gurevich, Basil Al-Hadithi, Agustín Jiménez, Alexis Rocha, Daniel Gómez, Carlos Sarmiento. The incorporation of some of the topics which are now available, either in this book or in the interactive-gB was simply a must (as algorithmic information), others represent an initiation into fields we have to deepen (as information in biological sciences). But nonetheless, if we take into account all the concepts we have not weaved yet into the network of clarified concepts, metaphors, theories and prob- lems, then we can clearly state that we are at the very beginning. By simply looking into the interactive-gB’s list of open voices, which are still empty, or into the number of voice proposals we have not open yet, it is easy to conclude we are before a large and of course open enterprise.

glossariumBITri vii METHODOLOGICAL NOTES INTRODUCTION TO THE PRESENT EDITION

One could argue the situation is not as different as before; then why are we saying we are now facing a different horizon? This is entangled with the current rearrangement of BITrum’s activ- ities. On the one hand, we have more coherently organised the different endeavours we have been pushing along the years in order to bring about a more effective cooperation among BITrum’s members and other stakeholders; on the other hand, gB has been structured in three branches: a) interactive-gB, b) gB-journal, and c) book editions. Through a rationalisation of efforts, this new gB landscape obviously offers a multiplied effect regarding impact, dissemina- tion and educational applications. To cope with the new challenges gB team has been enlarged and put besides other three BITrum’s operating units: (i) domusBITae devoted to the deployment of telematic tools for the facilitation of the distributed and interdisciplinary community of re- searchers and educators cooperating in the development of information studies. (ii) PRIMER, oriented to the promotion, development and underpinning of interdisciplinary studies; and (iii) a Research Unit, integrated by the teams working on specific scientific projects. Through this reorganisation, gB offers a more coherent platform for the clarification and theo- retical enterprise BITrum has been aiming at since its beginnings, linking its development to BITrum’s information environment (dB), educational activities (PRIMER) and research pro- jects. Such interplay – albeit the autonomy of the respective operations – represents a nurturing flow that will provide a new life to the clarification goals of the gB in connection to real prob- lems and the education of scientist to tackle them. The activities deployed since 2014 under support of Ecuadorian institutions, in both research and education, constitute a powerful balloon to lift up our scientific enterprise. This book in itself represents a sign of it. It is a result of the cooperation agreement signed in 2014 between the University of the Peninsula of Santa Elena (UPSE) and BITrum, which targets at several collaborative activities concerning: the development and co-management – together with the University of León – of the glossariumBITri open journal; the development of educational pro- grams; the cooperation in interdisciplinary research projects. Furthermore, the Ecuadorian Na- tional Secretary of Higher Education, Science, Technology and Innovation (SENESCYT) is supporting in the field of interdisciplinary information studies – through the Prometeo Pro- gramme –: the development of theoretical work and practical applications, the training of re- searchers, the development of scientific networks, etc. On one side, BITrum warmly thanks this support to the interdisciplinary study of information provided by the UPSE and SENESCYT; on the other side, we offer our deep commitment to contribute to the great scientific and edu- cational effort Ecuador is doing since the constitution of 2008. We are convinced that the trans- disciplinary capabilities of the information studies offers a toehold for the intense integration of knowledge we nowadays need for coping with the complex challenges our societies that are facing regarding the coverage of basic needs, environment, peace, inequality, urban manage- ment, climate change, democratic issues, waste reduction… We can use the language of infor- mation to refer to the physical, biological, societal, technological reality, to address theoretical and practical issues. Then we have a fantastical tool for weaving the scientific enterprise in a more integrated fashion. José María Díaz Nafría Santa Elena (Ecuador), February 2015

viii glossariumBITri METHODOLOGICAL NOTES

Methodological notes

Methodology: pluralism and rightness The glossariumBITri is conceived as a cooperative work in the following sense: each voice has a responsible editor who regulates, animates and organize the discussion of the term and the different contributions provided by the rest of the authors. It is furthermore an open work in a very particular sense: it is electronically accessible and opened to gather new contributions and discussions at any voice. Hence, subsequent editions will constantly increase the extension and deepness of the different entries. Furthemore the glossariumBITri interdisciplinary insofar it gather scientists from different knowledge areas in which the informational notions play a central role. Moreover, basic con- cepts are trans-disciplinary, as far as they cross different disciplines and fields of knowledge and action. The glossariumBITri does not assume an informational paradigm above others, but it endeavors to expose all coherently without hiding the theoretical and practical conflicts. According to the conceived methodology for glossariumBITri’s elaboration, all editorial team members can participate in any article under the assumption of certain commitments: ― All members of the writing team –which is always open to whomever may be interested– are potential authors of ENTRIES for each proposed voice. Thus, each voice may gather several independent entries, or related through debates or criticism to previous contribu- tions. ― The EDITOR (one per voice) is committed to allocate each entry –with sufficient quality– in the final article in a structured way and without redundancy. At the same time, the editor can ask authors for further clarification or deepening here and there, improving the text, providing references, etc. ― For each article, there is a DISCUSSION space where members can make comments, crit- ics, suggestions, questions to the given entries. ― The COORDINATORS overview the elaboration of the glossariumBITri as a whole and coordinate the development of different tasks related to its development: management and development of the edition system, content review, correction request, layout, call organi- zation, dissemination, etc.

Abbreviations and article organisation As one can see in the adjacent example, right after the voice the usual designation in Spanish, French and German is shown between brackets, preceded by the initials S., F. and G. respec- tively.

glossariumBITri ix METHODOLOGICAL NOTES

Immediately after, the scientific or discipli- nary usage contexts, in which the article is developed, is indicated between square brackets. The goal has been to point out the field better suited to the usage of the term. Thereby there are voices of specific usage for certain theories (e.g., self-re-creation de- fined in the context of the Unified Theory of Information). On the other hand, “trans- disciplinary” has been used in the soft sense of crossing different disciplines (e.g., [trans- disciplinary, system theory]). As subindex going along the list of usage contexts, the object type to which the article refers to is highlighted. It can be: concept (e.g., autopoiesis), metaphor (e.g., infor- mation flow), theory (e.g., channel theory), theorem (e.g., fundamental theorems of Shannon), discipline (e.g., hermeneutics), problem (e.g., fo- toblogs and adolescents), or resource (e.g., semantic web). In case the article is large, the titles of the sections, in which the article is divided, are enumerated right after the heading. The article structure has been freely determined by the corresponding editors, striving for a systemization of the entries provided by authors or participants in discussions. For citation and bibliographic reference listing and style adapted to ISO 690 standard has been used. The authorship in indicated at the bottom of each article through abbreviations specified in the section devoted to the editorial team. “ed” denotes editor, “tr” translator. If only an abbre- viation is indicated at the article bottom this means the corresponding author has not received –or incorporated yet– contributions of other authors. Additionally other abbreviations and acronyms referred to right after the authors and editors’ abbreviation list.

Its goal is a transformation of technology from “reifi- cation to reintegration” (Feenberg 2002: 183). Feenberg’s critical theory questions techno- logical determinism, which he defines as “the deterministic assumption that technology has its own autonomous logic of development.

First person experi- ence then does not come from a transcenden- tal subject, but from ’pure feeling’, or First- ness. Thus, Firstness must be the unanalyza- ble, inexplicable, unintellectual basis which runs in a continuous stream through our lives and therefore is the sum total of conscious- ness. Thus, possibility is a good word for First- ness. Existence is an abstract possibility (First- ness) which is no-thing. Peirce equates being with Firstness, as is clear from these two tri- chotomies: (1) being, (2) actuality, (3) reality; and (1) possibility, (2) actuality, (3) necessity. Figure 1.

(Duke University / Faculty database Philosophy Arts & Sciences) In the second part he presents his alternative definition of knowledge: belief caused by in- formation. Here Dretske replaces the need for the justification of belief in the causality of in- formation. By this change he tries to over- come the problems (the counter examples of Gettier and the paradox of the lottery) that the classical epistemological theories usually pre- sented and also enfores a suitable argument against the thesis of radical skepticism. In the third and final part of the work, the au- thor's purpose is to offer a definition of the content of belief, explanatorily compatible with its characterists: its intentional character, the possibility of possessing a false content and its determined role in the conduct. The objective is fulfilled when it identifies the con- tent of the belief with fully digitized infor- mation. In the same way, the concepts are considered as internal structures that are dis- tinguished by their semantic content, and when they are exemplified, they apply a con- trol over the outputs (conducts) of the cogni- tive system.

H = ∑Pi H i = − ∑Pi pi ( j)log2 pi ( j) (bits) i i, j According to Floridi (2005), the entropy H might designate three equivalent quantities in the ideal case of a noiseless channel: 1) “the average amount of information per symbol produced by the informer”; 2) the “average amount of data deficit (Shannon´s uncer- tainty) that the informee has before inspection of the output of the informer”; 3) “informa- tional potentiality”. Since the first two interpretations assume that a defined uncertainty corresponds to each symbol (whether it is in the emission or recep- tion), it implies a certain tactical agreement re- garding to the →alphabet or the informational game in which the agents are immersed. In both cases, the information can be quantified under the condition that the probability distri- bution can be specified. Concerning the third interpretation, entropy might be understood in terms of a physical magnitude related to the amount of disorder in processes or systems conveying energy or information. The larger the entropy, the higher the number of physical states in which the system can be found, consequently, the more information it can refer to, or in other words, the specification of the state in which a certain system is requires more information as its entropy increases. Numerically, this is equivalent to the amount of information or data that has to be given in order to specify the state. References ― FLORIDI, L. (2005). Semantic Conceptions of In- formation. In E.

At the same time, glossariumBITri 207 SYSTEM THEORY extreme specialization of science and research generates a growing need for ST to handle complex practical problems of contemporary life. Although systems thinking can be traced back to ancient Egypt, ST as an area of study was developed by the works of Ludwig von Ber- talanffy, William Ross Ashby, Gregory Bateson, Kenneth E. Boulding, C. West Churchman, Heinz von Förster, Paul Lazars- feld, Kurt Lewin, Warren McCulloch, John von Neumann, Margaret Mead, Anatol Rapoport, Norbert Wiener and others in the 1950s. Between 1946 and 1953 ST was specif- ically catalyzed by the Society for General Sys- tems Research and the Macy Conferences (or- ganized in the US by the Josiah Macy, Jr. Foundation). Specific versions of Systems Theories exist in cybernetics and in the theory of adaptive sys- tems. Applications can be found in mathemat- ics and computing (control theory), system dy- namics (Jay Forrester), agent based modeling, systems engineering, biochemistry, theories of living systems, anthropology, sociology and social cybernetics, economics, ecology, politi- cal sciences, history, archeology, systems psy- chology, group dynamics and theories of or- ganization etc. References ― BERTALANFFY, L. von (1950).
