Theories of Information, Communication and Knowledge.

We offer a novel theory of information that differs from traditional accounts in two respects: (i) it explains information in terms of counterfactuals rather than conditional probabilities, and (ii) it does not make essential reference to doxastic states of subjects, and consequently allows for the sort of objective, reductive explanations of various notions in epistemology and philosophy of mind that many have wanted from an account of information.

This paper provides an interpretation of the Routley-Meyer semantics for a weak negation-free relevant logic using Israel and Perry's theory of information. In particular, Routley and Meyer's ternary accessibility relation is given an interpretation in information-theoretic terms.

The present paper is meant to summarise and enlighten the theoretical implications of the twin theories of text comprehension and of text compression. Compatibility and non-exclusiveness of particle-like analysis of language and wave-like analysis of intentionality are also demonstrated within the newly established quantum linguistics framework. The informative state of language is viewed as being relatively stable; once activated and subject to motion, therefore reaching a communicative state, different phenomena occur, which may be observed, analysed and visualised through CPP-TRS observational (...) devices. Relativity theory may therefore be organised in terms of quanta with continuity and no contradiction. (shrink)

Esta apresentação identifica os principais conceitos envolvidos na teoria semântica da informação na obra An Outline of a Semantic Theory of Information de Bar-Hillel e Carnap. Inicio indicando as influências e desdobramentos sobre a elaboração desta teoria, seguido dos principais conceitos que os autores usarão para tratar o conteúdo semânticodas sentenças. O ponto de partida são operações conjunto-teoréticas, inicialmente através das funções In e Cont. Mas a dificuldade com a adição os leva a especificar o conceito de informatividade (...) semântica por meio das funções cont e m, que avaliam o espaço lógico-probabilístico sentencial. Sendo inversamente definíveis, onde a altaprobabilidade de verdade de uma sentença implica em seu escasso conteúdo informacional. Com isto, os autores introduzem a função inf como a contribuição de uma sentença na identificação de qual descrição-de-estado possível é o caso. A partir disto, eles ajustam a teoria para tratar probabilidades experimental-indutivas entre hipótesese evidências. (shrink)

This essay critically analyzes Luciano Floridi’s ontological theory of informational privacy. Organized into two main parts, Part I examines some key foundational components of Floridi’s privacy theory and it considers some of the ways in which his framework purports to be superior to alternative theories of informational privacy. Part II poses two specific challenges for Floridi’s theory of informational privacy, arguing that an adequate privacy theory should be able to: (i) differentiate informational privacy from other kinds (...) of privacy, including psychological privacy; and (ii) distinguish between descriptive and normative aspects of informational privacy in a way that differentiates a (mere) loss of privacy from a violation of privacy. I argue that Floridi’s privacy theory, in its present form, does not explicitly address either challenge. However, I also argue that his ontological theory provides us with a novel way of analyzing the impact that digital technologies have had for informational privacy. I conclude by suggesting that Floridi’s privacy framework can be interpreted as containing the elements of a “personality theory of privacy,” which would be useful to examine in a separate study.

In this article, I summarise the ontological theory of informational privacy (an approach based on information ethics) and then discuss four types of interesting challenges confronting any theory of informational privacy: (1) parochial ontologies and non-Western approaches to informational privacy; (2) individualism and the anthropology of informational privacy; (3) the scope and limits of informational privacy; and (4) public, passive and active informational privacy. I argue that the ontological theory of informational privacy can cope with such (...) challenges fairly successfully. In the conclusion, I discuss some of the work that lies ahead. (shrink)

For largely historical reasons, information and communication technology in education has been heavily influenced by a form of constructivism based on the transmission and transformation of information. This approach has implications for both learning and teaching in the field. The assumptions underlying the approach are explored and a critique offered. Although the transmission approach is entrenched in procedures and pedagogies, it is increasingly challenged by an action-theoretical form of constructivism. In this 'ecology of ideas', the value of the (...) two theoretical stances might be judged in terms of their practical utility and the contributions they make to understanding ICT. (shrink)

What does it mean for an agent faced with choice under uncertainty to “know” something? While a variety of mathematical methods are available to construct formal models to answer this question, the combination of different approaches may lead to unsettling paradoxes. I propose a unified theory that eliminates such inconsistencies by relying on a sharp conceptual distinction between information the decision-maker observes and how much of that information she can cognitively process. The resulting model allows for natural (...) decision-theoretic characterizations of comparing different amounts of information. (shrink)

Deanna Kuhn's theory of informal argumentation (1991) evaluates arguments according to a theory/evidence model where subjects first articulate a theory and then must provide critical testing of alternatives on the basis of evidence. Using this model, Kuhn reports that many subjects fail to supply adequate evidence for their 'theories' and are often unable or unwilling to generate alternatives. In this paper an account of practical reasoning is provided that suggests an alternate interpretation for Kuhn's subjects' poor perfonnance. (...) It is argued that treating practical arguments as failed theoretical justifications causes Kuhn to misrepresent the contribution of many of her subjects' arguments. (shrink)

It has been argued that moral problems in relation to Information Technology (IT) require new theories of ethics. In recent years, an interesting new theory to address such concerns has been proposed, namely the theory of Information Ethics (IE). Despite the promise of IE, the theory has not enjoyed public discussion. The aim of this paper is to initiate such discussion by critically evaluating the theory of IE.

In 1962 a mimeographed sheet of paper fell into my possession. It had been prepared by Ernest Adams of the Philosophy Department at Berkeley as a handout for a colloquim. Headed 'SOME FALLACIES OF FORMAL LOGIC' it simply listed eleven little pieces of reasoning, all in ordinary English, and all absurd. I still have the sheet, and quote a couple of the arguments here to give the idea. • If you throw switch S and switch T, the motor will start. (...) There fore, either if you throw switch S the motor will start, or, if you throw switch T the motor will start. • It is not the case that if John passes history he will graduate. Therefore, John will pass history. The disconcerting thing about these inferences is, of course, that under the customary truth-functional interpretation of and, or, not, and if-then, they are supposed to be valid. What, if anything, is wrong? At first I was not disturbed by the examples. Having at that time consider able personal commitment to rationality in general and formal logic in par ticular, I felt it my duty and found myself easily able (or so I thought) to explain away most of them. But on reflection I had to admit that my expla nations had an ad hoc character, varying suspiciously from example to example. (shrink)

Although the principle of informed consent is well established and its importance widely acknowledged, it has met with criticism for decades. Doubts have been raised for a number of different reasons. In particular, empirical data show that people regularly fail to reproduce the information provided to them. Many critics agree, therefore, that the received concept of informed consent is no more than a myth. Strategies to overcome this problem often rest on a flawed concept of informed consent. In this (...) paper, it is suggested that informed consent is a communicative act between two persons. The challenge is to elucidate the norms and constraints for successfully performing such a communicative act. The view developed here has major consequences with regard to the standards for information disclosure as well as for the general scope of informed consent. (shrink)

Why do human beings make and accept promises? What human interest is served by this procedure? Many hold that promising serves what I shall call an information interest, an interest in information about what will happen. And they hold that human beings ought to keep their promises because breaches of promise threaten this interest. On this view human beings take promises seriously because we want correct information about how other human beings are going to act. Some such (...) view is taken for granted by most philosophical accounts of promissory obligation.1 I agree that human beings do want such information and that they often get it by accepting promises. But I doubt that promising exists because it serves this information interest. (shrink)

Informational theories of semantic content have been recently gaining prominence in the debate on the notion of mental representation. In this paper we examine new-wave informational theories which have a special focus on cognitive science. In particular, we argue that these theories face four important difficulties: they do not fully solve the problem of error, fall prey to the wrong distality attribution problem, have serious difficulties accounting for ambiguous and redundant representations and fail to deliver a metasemantic theory of (...) representation. Furthermore, we argue that these difficulties derive from their exclusive reliance on the notion of information, so we suggest that pure informational accounts should be complemented with functional approaches.

This essay employs Charles Peirce’s triadic semiotics in order to develop a biosemiotic theory of life that is capable of illuminating the function of information in living systems. Specifically, I argue that the relationship between biological information structures , selecting environments, and the adapted bodily processes of living organisms is aptly modelled by the irreducibly triadic relationship between Peirce’s sign, object, and interpretant, respectively. In each instance of information-based semiosis, the information structure is a complex (...) informational sign that represents the informational object ; and the bodily, behavioral, mental, or intellectual processes that are organized by the informational sign to more or less accurately interpret the present environment constitute a complex informational interpretant—a living, interpreting organism. The essay begins by discussing the precise sense in which this biosemiotic theory is based upon Charles Peirce’s semiotic theory. Next, the theory is developed at length in relation to genetic information structures. Finally, I present a brief outline of how the theory applies to neural and linguistic information structures. The essay concludes with a reflection upon the anti-reductionist implications of the theory. (shrink)

Non-technical introduction to Giulio Tononi's Integrated Information Theory of consciousness.

With 500+ papers and 20+ books spanning many scientific disciplines, Mark Burgin has left an indelible mark and legacy for future explorers of human thought and information technology professionals. In this paper, I discuss his contribution to the evolution of machine intelligence using his general theory of information (GTI) based on my discussions with him and various papers I co-authored during the past eight years. His construction of a new class of digital automata to overcome the barrier (...) posed by the Church–Turing Thesis, and his contribution to super-symbolic computing with knowledge structures, cognizing oracles, and structural machines are leading to practical applications changing the future landscape of information systems. GTI provides a model for the operational knowledge of biological systems to build, operate, and manage life processes using 30+ trillion cells capable of replication and metabolism. The schema and associated operations derived from GTI are also used to model a digital genome specifying the operational knowledge of algorithms executing the software life processes with specific purposes using replication and metabolism. The result is a digital software system with a super-symbolic computing structure exhibiting autopoietic and cognitive behaviors that biological systems also exhibit. We discuss here one of these applications. (shrink)

Information processing in neural systems can be described and analyzed at multiple spatiotemporal scales. Generally, information at lower levels is more fine-grained but can be coarse-grained at higher levels. However, only information processed at specific scales of coarse-graining appears to be available for conscious awareness. We do not have direct experience of information available at the scale of individual neurons, which is noisy and highly stochastic. Neither do we have experience of more macro-scale interactions, such as (...) interpersonal communications. Neurophysiological evidence suggests that conscious experiences co-vary with information encoded in coarse-grained neural states such as the firing pattern of a population of neurons. In this article, we introduce a new informational theory of consciousness: Information Closure Theory of Consciousness (ICT). We hypothesize that conscious processes are processes which form non-trivial informational closure (NTIC) with respect to the environment at certain coarse-grained scales. This hypothesis implies that conscious experience is confined due to informational closure from conscious processing to other coarse-grained scales. Information Closure Theory of Consciousness (ICT) proposes new quantitative definitions of both conscious content and conscious level. With the parsimonious definitions and a hypothesize, ICT provides explanations and predictions of various phenomena associated with consciousness. The implications of ICT naturally reconcile issues in many existing theories of consciousness and provides explanations for many of our intuitions about consciousness. Most importantly, ICT demonstrates that information can be the common language between consciousness and physical reality. (shrink)

First comprehensive introduction to information theory explores the work of Shannon, McMillan, Feinstein, and Khinchin. Topics include the entropy concept in probability theory, fundamental theorems, and other subjects. 1957 edition.

Recent work in quantum information science has produced a revolution in our understanding of quantum entanglement. Scientists now view entanglement as a physical resource with many important applications. These range from quantum computers, which would be able to compute exponentially faster than classical computers, to quantum cryptographic techniques, which could provide unbreakable codes for the transfer of secret information over public channels. These important advances in the study of quantum entanglement and information touch on deep foundational issues (...) in both physics and philosophy. This interdisciplinary volume brings together fourteen of the world's leading physicists and philosophers of physics to address the most important developments and debates in this exciting area of research. It offers a broad spectrum of approaches to resolving deep foundational challenges - philosophical, mathematical, and physical - raised by quantum information, quantum processing, and entanglement. This book is ideal for historians, philosophers of science and physicists"--Provided by publisher. (shrink)

A naturalistic scheme of primitive conceptual representations is proposed using the statistical measure of mutual information. It is argued that a concept represents, not the class of objects that caused its tokening, but the class of objects that is most likely to have caused it (had it been tokened), as specified by the statistical measure of mutual information. This solves the problem of misrepresentation which plagues causal accounts, by taking the representation relation to be determined via ordinal relationships (...) between conditional probabilities. The scheme can deal with statistical biases and does not rely on arbitrary criteria. Implications for the theory of meaning and semantic content are addressed. (shrink)

Information technology, that assortment of technology that enables the conversion of data into information, has had an enormous impact on the field of public administration and its theoretical foundation. This article explores five of them. It begins with a discussion of one of the primary impacts of information technology on public administration theory: the development of systems theory and its descendants including the study of complex systems, chaos, and complexity theory. The importance of (...) class='Hi'>information technology in decision-making is explored next. Does information technology free us from the limits of bounded rationality or are we simply overwhelmed by the volume of information available via new sources, such as the Internet and the World Wide Web? The third role examined is the use of information technology as a research tool to make previously intractable problems solvable. Computer capability has enormously advanced the theoretical underpinnings of public administration. Fourth, the significance of information technology as a change agent that calls for revision of other theoretical postulates is investigated. As information technology has diffused into public organizations, how has it called into question what we previously thought about the foundation of bureaucracy? Finally, learning by doing and the manner through which practice informs theory is considered. (shrink)

In this paper, I examine the comparatively neglected intuition of production regarding causality. I begin by examining the weaknesses of current production accounts of causality. I then distinguish between giving a good production account of causality and a good account of production. I argue that an account of production is needed to make sense of vital practices in causal inference. Finally, I offer an information transmission account of production based on John Collier’s work that solves the primary weaknesses of (...) current production accounts: applicability and absences.

Cohen and Meskin 2006 recently offered a counterfactual theory of information to replace the standard probabilistic theory of information. They claim that the counterfactual theory fares better than the standard account on three grounds: first, it provides a better framework for explaining information flow properties; second, it requires a less expensive ontology; and third, because it does not refer to doxastic states of the information-receiving organism, it provides an objective basis. In this paper, (...) I show that none of these is really an advantage. Moreover, the counterfactual theory fails to satisfy one of the basic properties of information flow, namely the Conjunction principle. Thus, I conclude, there is no reason to give up the standard probabilistic theory for the counterfactual theory of information. (shrink)

The papers collected in this volume exemplify some of the trends in current approaches to logic, language and computation. Written by authors with varied academic backgrounds, the contributions are intended for an interdisciplinary audience. The first part of this volume addresses issues relevant for multi-agent systems: reasoning with incomplete information, reasoning about knowledge and beliefs, and reasoning about games. Proofs as formal objects form the subject of Part II. Topics covered include: contributions on logical frameworks, linear logic, and different (...) approaches to formalized reasoning. Part III focuses on representations and formal methods in linguistic theory, addressing the areas of comparative and temporal expressions, modal subordination, and compositionality. (shrink)
