This chapter has two goals. The first is to explain concepts associated with information and computation in physical terms. The other goal of this chapter is to analyze concepts in physics like space, time, and causality in information-theoretic and computational terms.

This article tells the story of Ed Fredkin, a pilot, programmer, engineer, hardware designer and entrepreneur, whose work inside and outside academia has influenced major developments in computer science and in the foundations of theoretical physics for the past fifty years.

Doctoral programs at U.S. universities play a critical role in the development of human resources both in the United States and abroad. This volume reports the results of an extensive study of U.S. research-doctorate programs in five broad fields: physical sciences and mathematics, engineering, social and behavioral sciences, biological sciences, and the humanities. Research-Doctorate Programs in the United States documents changes that have taken place in the size, structure, and quality of doctoral education since the widely used 1982 editions. This (...) update provides selected information on nearly 4,000 doctoral programs in 41 subdisciplines at 274 doctorate-granting institutions. This volume also reports the results of the National Survey of Graduate Faculty, which polled a sample of faculty for their views on the scholarly quality of program faculty and the effectiveness of doctoral programs in preparing research scholars/scientists. This much-anticipated update of such an essential reference will be useful to education administrators, university faculty, and students seeking authoritative information on doctoral programs.

The general concept of information does not belong in the category of universal and inexorable physical laws but in the category of initial conditions and boundary conditions. Boundary conditions formed by local structures are often called constraints. Informational structures such as symbol vehicles are a special type of constraint. It should be clear that the concepts of initial conditions and constraints in physics make no sense outside the context of the law-based physical dynamics to which they apply. This (...) is also the case for the concept of information. -/- . (shrink)

. The origin and history of Landauer’s principle is traced through the development of the thermodynamics of computation at IBM from 1959 to 1982. This development was characterized by multiple conceptual shifts: memory came to be seen not as information storage, but as delayed information transmission; information itself was seen not as a disembodied logical entity, but as participating in the physical world; and logical irreversibility was connected with physical, thermodynamic, irreversibility. These conceptual shifts were characterized by (...) an ambivalence opposing strong metaphysical claims to practical considerations. Three sorts of practical considerations are discussed. First, these conceptual shifts engaged materials central to IBM’s business practice. Second, arguments for metaphysical certainties were made with reference to the practical functioning of typical computers. Third, arguments for metaphysical certainties were made in the context of establishing the thermodynamics of information as a sub-discipline of physics. (shrink)

Quantum information theory has given rise to a renewed interest in, and a new perspective on, the old issue of understanding the ways in which quantum mechanics differs from classical mechanics. The task of distinguishing between quantum and classical theory is facilitated by neutral frameworks that embrace both classical and quantum theory. In this paper, I discuss two approaches to this endeavour, the algebraic approach, and the convex set approach, with an eye to the strengths of each, and the (...) relations between the two. I end with a discussion of one particular model, the toy theory devised by Rob Spekkens, which, with minor modifications, fits neatly within the convex sets framework, and which displays in an elegant manner some of the similarities and differences between classical and quantum theories. The conclusion suggested by this investigation is that Schrödinger was right to find the essential difference between classical and quantum theory in their handling of composite systems, though Schrödinger's contention that it is entanglement that is the distinctive feature of quantum mechanics needs to be modified.

During the refereeing procedure of Anthropomorphic Quantum Darwinism by Thomas Durt, it became apparent in the dialogue between him and me that the definition of information in Physics is something about which not all authors agreed. This text aims at describing the concepts associated to information that are accepted as the standard in the Physics world community.

We examine the problem of the existence (in classical and/or quantum physics) of longitudinal limitations of measurability, defined as limitations preventing the measurement of a given quantity with arbitrarily high accuracy. We consider a measuring device as a generalized communication system, which enables us to use methods of information theory. As a direct consequence of the Shannon theorem on channel capacity, we obtain an inequality which limits the accuracy of a measurement in terms of the average power necessary (...) to transmit the information content of the measurement itself. This inequality holds in a classical as well as in a quantum framework. (shrink)

As was mentioned by Nicolas Lori in his (Found Sci, 2010 ) commentary, the definition of Information in Physics is something about which not all authors agreed. According to physicists like me Information decreases when Entropy increases (so entropy would be a negative measure of information), while many physicists, seemingly the majority of them, are convinced of the contrary (even in the camp of Quantum Information Theoreticians). In this reply I reproduce, and make more precise, (...) some of my arguments, that appeared here and there in my ( 2010 ) paper, in order to clarify the presentation of my personal point of view on the subject.

According to quantum mechanics, the informational content of isolated systems does not change in time. Considering composite systems, it would be very useful to identify suitable indicators able to quantify the informational content of the single parts and to describe their evolution through balance equations, as it happens in the case of energy. Reasoning on the basic concepts of quantum mechanics, we show that there is an intrinsic quantum information encoded in the coherence of quantum states. Such information (...) is measured by a function, called here coherent entropy, which turns out to be complementary to the von-Neumann entropy. We show that the total quantum information of multipartite systems is determined by the coherent entropy of the single subsystems plus their mutual information. Interestingly, the coherent entropy is found to be equal to the information conveyed in the future by quantum states, providing a further inspiring interpretation to this quantity. The vision proposed in this paper also suggests a natural and simple definition of an indicator for nonlocal correlations. (shrink)

ArgumentIn this comparative historical analysis, we will analyze the intellectual tendency that emerged between 1946 and 1956 to take advantage of the popularity of communication theory to develop a kind of informational epistemology of statistical mechanics. We will argue that this tendency results from a historical confluence in the early 1950s of certain theoretical claims of the so-called English School of Information Theory, championed by authors such as Gabor (1956) or MacKay (1969), and from the attempt to extend the (...) profound success of Shannon’s ([1948] 1993) technical theory of sign transmission to the field of statistical thermal physics. As a paradigmatic example of this tendency, we will evaluate the intellectual work of Léon Brillouin (1956), who, in the mid-fifties, developed an information theoretical approach to statistical mechanical physics based on a concept of information linked to the knowledge of the observer.

As one may have noticed, the title of this paper is somewhat provocative. We found Roman Krzanowski’s (2020a,b,c; 2022) proposed approach to the problem of information very intriguing. Our aim here is to highlight some advantages when it comes to answering some fundamental questions in the philosophy of physics and metaphysics, as well as the philosophy of information and computer science. This issue is of great importance, so we propose that the introduction of some subtle distinctions between (...) ontological and epistemological information can be regarded as being analogous to G.F.R. Ellis’s analyses of the passage of time in his concept of the Crystallizing Block Universe (Ellis and Goswami, 2012). This analogy could be useful when further studying the relations between different types of information. We also suggest some subjects for further study, ones where Krzanowski’s proposal could serve as a very solid foundation for examining traditional metaphysical issues by combining classical philosophical doctrines with the new approach.

Many scientists regard mass and energy as the primary currency of nature. In recent years, however, the concept of information has gained importance. In this book, eminent scientists, philosophers, and theologians chart various aspects of information, from quantum information to biological and digital information, in order to understand how nature works. Beginning with a historical treatment of the topic, the book also examines physical and biological approaches to information, and the philosophical, theological, and ethical implications.

Representation is typically taken to be importantly separate from its physical implementation. This is exemplified in Marr’s three-level framework, widely cited and often adopted in neuroscience. However, the separation between representation and physical implementation is not a necessary feature of information-processing systems. In particular, when it comes to analog computational systems, Marr’s representational/algorithmic level and implementational level collapse into a single level. Insofar as analog computation is a better way of understanding neural computation than other notions, Marr’s three-level framework (...) must then be amended into a two-level framework. However, far from being a problem or limitation, this sheds lights on how to understand physical media as being representational, but without a separate, medium-independent representational level.

The pre-eminence of logical dynamics, over a static and purely propositional view of Logic, lies at the core of a new understanding of both formal epistemology and the logical foundations of quantum mechanics. Both areas appear at first sight to be based on purely static propositional formalisms, but in our view their fundamental operators are essentially dynamic in nature. Quantum logic can be best understood as the logic of physically-constrained informational interactions between subsystems of a global physical system. Similarly, epistemic (...) logic is the logic of socially-constrained informational interactions between “subsystems” of a social system. Dynamic Epistemic Logic provides us with a unifying setting in which these informational interactions, coming from seemingly very different areas of research, can be fully compared and analyzed. The DEL formalism comes with a powerful set of tools that allows us to make the underlying dynamic/interactive mechanisms fully transparent. (shrink)

Every manifestation of information, semiosis and meaning we have been able to study experimentally has a physical form. Neglect of their dynamical (energetic) ground tends towards dualism or idealism, leaving the causal basis of semiosis and the causal powers of representations mysterious. Consideration of the necessary physical requirements for the embodiment of semiotic categories imposes a discipline on semiotics required for its integration into the rest of science, especially for the emerging field of biosemiotics, as well as any future (...) extensions to chemistry physics or other realms that might constitute a general, primal semiotics. Without this discipline, or something equally strong, there is a risk of projection of anthropomorphic semiotic terminology onto unsuitable hosts, leading, if unchecked, to the sort of animism that biology in particular has only recently escaped. The problem is suspect whenever teleological notions are used outside of mental or social contexts.1 Although our animistic ancestors may have had a closer rapport with Nature than modern scientists, contemporary scientific explanation requires an understanding of causal structure (Salmon 1984). On the other hand, unless the causal rendition of semiosis can capture full blown cognitive semiosis, it is likely to be too restrictive for the evaluation of primal semiosis in general. (shrink)

Information is a recognized fundamental notion across the sciences and humanities, which is crucial to understanding physical computation, communication, and human cognition. The Philosophy of Information brings together the most important perspectives on information. It includes major technical approaches, while also setting out the historical backgrounds of information as well as its contemporary role in many academic fields. Also, special unifying topics are high-lighted that play across many fields, while we also aim at identifying relevant themes (...) for philosophical reflection. There is no established area yet of Philosophy of Information, and this Handbook can help shape one, making sure it is well grounded in scientific expertise. As a side benefit, a book like this can facilitate contacts and collaboration among diverse academic milieus sharing a common interest in information. . First overview of the formal and technical issues involved in the philosophy of information . Integrated presentation of major mathematical approaches to information, form computer science, information theory, and logic .

Computers today are not only the calculation tools - they are directly (inter)acting in the physical world which itself may be conceived of as the universal computer (Zuse, Fredkin, Wolfram, Chaitin, Lloyd). In expanding its domains from abstract logical symbol manipulation to physical embedded and networked devices, computing goes beyond Church-Turing limit (Copeland, Siegelman, Burgin, Schachter). Computational processes are distributed, reactive, interactive, agent-based and concurrent. The main criterion of success of computation is not its termination, but the adequacy of its (...) response, its speed, generality and flexibility; adaptability, and tolerance to noise, error,faults, and damage. Interactive computing is a generalization of Turing computing, and it calls for new conceptualizations (Goldin, Wegner). In the info-computationalist framework, with computation seen as information processing, natural computation appears as the most suitable paradigm of computation and information semantics requires logical pluralism.

Information was a frequently used concept in many fields of investigation. However, this concept is still not really understood, when it is referred for instance to consciousness and its informational structure. In this paper it is followed the concept of information from philosophical to physics perspective, showing especially how this concept could be extended to matter in general and to the living in particular, as a result of the intimate interaction between matter and information, the human (...) body appearing as a bipolar informed-matter structure. It is detailed on this way how this concept could be referred to consciousness, and an informational modeling of consciousness as an informational system of the human body is presented. Based on the anatomic architecture of the organism and on the inference of the specific information concepts, it is shown that the informational system of the human body could be described by seven informational subsystems, which are reflected in consciousness as corresponding cognitive centers. These results are able to explain the main properties of consciousness, both the cognitive and extra-cognitive properties of the mind, like that observed during the near-death experiences and other similar phenomena. Moreover, the results of such a modeling are compared with the existing empirical concepts and models on the energetic architecture of the organism, showing their relevance for the understanding of consciousness.

Modern information technologies rely on electronic and optical signals transmitting data, expressions, and other signals around the world. Digital networks account for trillions of dollars worth of worldwide commerce, but the nature of their objects is complicated and has proven to be a challenge for customary and legal modes of ownership for expressions. Intellectual property law governed expressions and inventions for the past couple hundred years, but software and other digital objects, due to their ephemeral and non-physical natures, pose (...) some ontological, ethical, and regulatory challenges discussed in this chapter.

Information is a peculiar quantity. Unlike matter and energy, which are conserved by the laws of physics, the aggregation of knowledge from many sources can in fact produce more information (synergy) or less (redundancy) than the sum of its parts. This feature can endow groups with problem‐solving strategies that are superior to those possible among noninteracting individuals and, in turn, may provide a selection drive toward collective cooperation and coordination. Here we explore the formal properties of (...) class='Hi'>information aggregation as a general principle for explaining features of social organization. We quantify information in terms of the general formalism of information theory, which also prescribes the rules of how different pieces of evidence inform the solution of a given problem. We then show how several canonical examples of collective cognition and coordination can be understood through principles of minimization of uncertainty (maximization of predictability) under information pooling over many individuals. We discuss in some detail how collective coordination in swarms, markets, natural language processing, and collaborative filtering may be guided by the optimal aggregation of information in social collectives. We also identify circumstances when these processes fail, leading, for example, to inefficient markets. The contrast to approaches to understand coordination and collaboration via decision and game theory is also briefly discussed. (shrink)

Starting from a philosophical perspective, which states that the living structures are actually a combination between matter and information, this article presents the results on an analysis of the bipolar information-matter structure of the human organism, distinguishing three fundamental circuits for its survival, which demonstrates and supports this statement, as a base for further development of the informational model of consciousness to a general informational model of the human organism. For this, it was examined the Informational System of (...) the Human Body and its components from the perspective of the physics/information/neurosciences concepts, showing specific functions of each of them, highlighting the correspondence of these centers with brain support areas and with their projections in consciousness, which are: Center of Acquisition and Storing of Information (CASI) reflected in consciousness as memory, Center of Decision and Command (CDC) (decision), Info-Emotional Center (IES) (emotions), Maintenance Informational System (MIS) (personal status), Genetic Transmission System (GTS) (associativity/genetic transmission) and Info Genetic Generator (IGG) related by the body development and inherited behaviors. The Info Connection (IC), detected in consciousness as trust and confidence can explain the Near-Death Experiences (NDEs) and associated phenomena. This connection is antientropic and informational, because from the multitude of uncertain possibilities is selected a certain one, helping/supporting the survival and life. The human body appears therefore as a bipolar structure, connected to two poles: information and matter. It is argued that the survival, which is the main objective of the organism, is complied in three main ways, by means of: (i) the reactive operation for adaptation by attitude; (ii) the info-genetic integration of information by epigenetic processes and genetic transmission of information for species survival, both circuits (i) and (ii) being associated to the information pole; (iii) maintenance of the material body (defined as informed matter) and its functions, associated to the matter pole of the organism. It results therefore that the informational system of the human body is supported by seven informational circuits formed by the neuro-connections between the specific zones of the brain corresponding to the informational subsystems, the cognitive centers, the sensors, transducers and execution (motor/mobile) elements. The fundamental informational circuits assuring the survival are the reactive circuit, expressible by attitude, the epigenetic/genetic circuit, absorbing and codifying information to be transmitted to the next generations, and the metabolic circuit, connected to matter (matter pole). The presented analysis allows to extend the informational modeling of consciousness to an Informational Model of Consciousness and Organism, fully describing the composition/functions of the organism in terms of information/matter and neurosciences concept.

The physical process of observation is considered from a specific information theoretical viewpoint. Using the modified concept of an information based on infinite alternatives, a formalism is derived describing the elementary transfer of one bit of information. This bit of information is produced on a virtual (nonreal) sub-quantum level of physical description. The interpretation of the formalism yields the following, complementary points: (i) the effect of spatiotemporal delocalization on the sub-quantum level, and (ii) a possible access (...) to the concept of chaos as an intrinsic property of quantum systems. As a brief example, elementary information transfer is illustrated in a cosmological context. Finally, a formal approach to information production on the sub-quantum level is sketched on the basis of complex time. (shrink)

In this paper I defend an intermediate position between the ‘bare mathematical results’ view and the ‘transmission’ view of mathematical explanations of physical phenomena (MEPPs). I argue that, in MEPPs, it is not enough to deduce the explanandum from the generalizations cited in the explanans. Rather, we must add information regarding why those generalizations obtain. However, I also argue that it is not necessary to provide explanatory proofs of the mathematical theorems that represent those generalizations. I illustrate this with (...) the bridges of Königsberg case. -/- . (shrink)

As historian Henning Schmidgen notes, the scientific study of the nervous system would have been “unthinkable” without the industrialization of communication in the 1830s. Historians have investigated extensively the way nerve physiologists have borrowed concepts and tools from the field of communications, particularly regarding the nineteenth-century work of figures like Helmholtz and in the American Cold War Era. The following focuses specifically on the interwar research of the Cambridge physiologist Edgar Douglas Adrian, and on the technology that led to his (...) Nobel-Prize-winning research, the thermionic vacuum tube. Many countries used the vacuum tube during the war for the purpose of amplifying and intercepting coded messages. These events provided a context for Adrian's evolving understanding of the nerve fiber in the 1920s. In particular, they provide the background for Adrian's transition around 1926 to describing the nerve impulse in terms of “information,” “messages,” “signals,” or even “codes,” and for translating the basic principles of the nerve, such as the all-or-none principle and adaptation, into such an “informational” context. The following also places Adrian's research in the broader context of the changing relationship between science and technology, and between physics and physiology, in the first few decades of the twentieth century.

Quantum information science is a source of task-related axioms whose consequences can be explored in general settings encompassing quantum mechanics, classical theory, and more. Quantum states are compendia of probabilities for the outcomes of possible operations we may perform on a system: ''operational states.'' I discuss general frameworks for ''operational theories'' (sets of possible operational states of a system), in which convexity plays key role. The main technical content of the paper is in a theorem that any such theory (...) naturally gives rise to a ''weak effect algebra'' when outcomes having the same probability in all states are identified and in the introduction of a notion of ''operation algebra'' that also takes account of sequential and conditional operations. Such frameworks are appropriate for investigating what things look like from an ''inside view,'' i.e., for describing perspectival information that one subsystem of the world can have about another. Understanding how such views can combine, and whether an overall ''geometric'' picture (''outside view'') coordinating them all can be had, even if this picture is very different in structure from the perspectives within it, is the key to whether we may be able to achieve a unified, ''objective'' physical view in which quantum mechanics is the appropriate description for certain perspectives, or whether quantum mechanics is truly telling us we must go beyond this ''geometric'' conception of physics.

Much scholarship has claimed the physics of Emilie du Châtelet’s treatise, Institutions de physique, is Newtonian. I argue against that idea. To do so, I distinguish three strands of meaning for the category ‘Newtonian science,’ and I examine her book against them. I conclude that her physics is not Newtonian in any useful or informative sense. To capture what is specific about it, we need better interpretive categories.

We analyse the contention that privacy is an alien concept within Japanese society, put forward in various presentations of Japanese cultural norms at least as far back as Benedict in The chrysanthemum and the sword: patterns of Japanese culture. Houghton Mifflin, Boston, 1946. In this paper we distinguish between information privacy and physical privacy. As we show, there is good evidence for social norms of limits on the sharing and use of personal information (i.e. information privacy) from (...) traditional interactions in Japanese society, as well as constitutional evidence from the late 19th century (in the Meiji Constitution of 1889). In this context the growing awareness of the Japanese public about problems with networked information processing by public sector and commercial organisations from the 1980s (when a law governing public sector use of personal information was first passed) to recent years (when that law was updated and a first law governing commercial use of personal information was adopted) are not the imposition or adoption of foreign practices nor solely an attempt to lead Japanese society into coherence with the rest of the OECD. Instead they are drawing on the experience of the rest of the developed world in developing legal responses to the breakdown of social norms governing interchange and use of personal information, stressed by the architectural changes wrought by networked information processing capabilities. This claim is supported by consideration of standard models of Japanese social interactions as well as of Supreme Court judgements declaring reasonable expectations of protection of privacy to hold in Japan.

Christopher Timpson proposes a deflationary view about information, according to which the term ‘information’ is an abstract noun and, as a consequence, information is not part of the material contents of the world. The main purpose of the present article consists in supplying a critical analysis of this proposal, which will lead us to conclude that information is an item even more abstract than what Timpson claims. From this view, we embrace a pluralist stance that recognizes (...) the legitimacy of different interpretations of the concept of information. (shrink)

This paper presents Integrated Information Theory (IIT) 4.0. IIT aims to account for the properties of experience in physical (operational) terms. It identifies the essential properties of experience (axioms), infers the necessary and sufficient properties that its substrate must satisfy (postulates), and expresses them in mathematical terms. In principle, the postulates can be applied to any system of units in a state to determine whether it is conscious, to what degree, and in what way. IIT offers a parsimonious explanation (...) of empirical evidence, makes testable predictions, and permits inferences and extrapolations. IIT 4.0 incorporates several developments of the past ten years, including a more accurate translation of axioms into postulates and mathematical expressions, the introduction of a unique measure of intrinsic information that is consistent with the postulates, and an explicit assessment of causal relations. By fully unfolding a system's irreducible cause-effect power, the distinctions and relations specified by a substrate can account for the quality of experience. (shrink)

Although a substantial number of papers is published on the topic of consciousness, there is still little consensus on what its nature is and how the physical and phenomenal worlds are connected. Most published research establishes a causal relation between the brain and the mind, but it lacks a cogent theory of how this relation comes to be. In contrast, this paper uses a set of thought experiments grounded in quantum information theory to derive a framework for resolving the (...) hard problem of consciousness. Despite the common tendency to treat the problem purely philosophically, in this paper, consciousness and qualia are analyzed through established formal theory deriving conclusions regarding their relation which provide counter-arguments for the commonly held dualist view. Through the informational monism framework, a case is made for a fundamentally phenomenal nature of information. (shrink)

Shannon's notion of relative information between two physical systems can function as foundation for statistical mechanics and quantum mechanics, without referring to subjectivism or idealism. It can also represent a key missing element in the foundation of the naturalistic picture of the world, providing the conceptual tool for dealing with its apparent limitations. I comment on the relation between these ideas and Democritus.

An ontology of information belies our common intuitions about reality today and animates and governs both explicit scholarly study in philosophy and the sciences as well as the ideologies that are growing out of them. Transhumanism is one such technoscientific ideology that holds to a very specific ontology of information which need not be the only one on offer. This article argues that the transhumanist ontology of information exhibits gnostic and docetic religious overtones in it and that (...) it devalues physical existence. At the same time, despite claiming a rejection of supernature, hypothetical transhumanist practices (such as mind‐uploading) posit the infosphere as a kind of supernatural realm that is often set in opposition to the natural world. This article presents a critique of transhumanist conceptions of information and offers an alternative ontology of information that more adequately accounts for the distinction between the natural and supernatural as well as the integrity of the physical world.

Quantum mechanics was reformulated as an information theory involving a generalized kind of information, namely quantum information, in the end of the last century. Quantum mechanics is the most fundamental physical theory referring to all claiming to be physical. Any physical entity turns out to be quantum information in the final analysis. A quantum bit is the unit of quantum information, and it is a generalization of the unit of classical information, a bit, as (...) well as the quantum information itself is a generalization of classical information. Classical information refers to finite series or sets while quantum information, to infinite ones. Quantum information as well as classical information is a dimensionless quantity. Quantum information can be considered as a “bridge” between the mathematical and physical. The standard and common scientific epistemology grants the gap between the mathematical models and physical reality. The conception of truth as adequacy is what is able to transfer “over” that gap. One should explain how quantum information being a continuous transition between the physical and mathematical may refer to truth as adequacy and thus to the usual scientific epistemology and methodology. If it is the overall substance of anything claiming to be physical, one can question how different and dimensional physical quantities appear. Quantum information can be discussed as the counterpart of action. Quantum information is what is conserved, action is what is changed in virtue of the fundamental theorems of Emmy Noether (1918). The gap between mathematical models and physical reality, needing truth as adequacy to be overcome, is substituted by the openness of choice. That openness in turn can be interpreted as the openness of the present as a different concept of truth recollecting Heidegger’s one as “unconcealment” (ἀλήθεια). Quantum information as what is conserved can be thought as the conservation of that openness. (shrink)

The post-Westphalian Nation State developed by becoming more and more an Information Society. However, in so doing, it progressively made itself less and less the main information agent, because one of the main forces that made the Nation State possible and then predominant, as a historical driving force in human politics, namely Information and Communication Technologies (ICTs), is also what is now making it less central, in the social, political and economic life of humanity across the world. (...) ICTs enable and promote the agile, temporary and timely aggregation, disaggregation and re-aggregation of distributed groups around shared interests across old, rigid boundaries represented by social classes, political parties, ethnicity, language barriers, physical and geographical barriers, and so forth. Similar novelties call for a serious exercise in conceptual re-engineering. This paper argues for the need to understand how the new informational multiagent systems may be designed in such a way as to take full advantage of the socio-political progress made so far, while being able to deal successfully with the new global challenges (from the environment to the financial markets) that are undermining the legacy of that very progress.

Probabilistic theories are a natural framework to investigate the foundations of quantum theory and possible alternative or deeper theories. In a generic probabilistic theory, states of a physical system are represented as vectors of outcomes probabilities and state spaces are convex cones. In this picture the physics of a given theory is related to the geometric shape of the cone of states. In quantum theory, for instance, the shape of the cone of states corresponds to a projective space over (...) complex numbers. In this paper we investigate geometric constraints on the state space of a generic theory imposed by the following information theoretic requirements: every non completely mixed state of a system is perfectly distinguishable from some other state in a single shot measurement; information capacity of physical systems is conserved under making mixtures of states. These assumptions guarantee that a generic physical system satisfies a natural principle asserting that the more a state of the system is mixed the less information can be stored in the system using that state as logical value. We show that all theories satisfying the above assumptions are such that the shape of their cones of states is that of a projective space over a generic field of numbers. Remarkably, these theories constitute generalizations of quantum theory where superposition principle holds with coefficients pertaining to a generic field of numbers in place of complex numbers. If the field of numbers is trivial and contains only one element we obtain classical theory. This result tells that superposition principle is quite common among probabilistic theories while its absence gives evidence of either classical theory or an implausible theory. (shrink)

Twenty five years ago, Sir John Carew Eccles together with Friedrich Beck proposed a quantum mechanical model of neurotransmitter release at synapses in the human cerebral cortex. The model endorsed causal influence of human consciousness upon the functioning of synapses in the brain through quantum tunneling of unidentified quasiparticles that trigger the exocytosis of synaptic vesicles, thereby initiating the transmission of information from the presynaptic towards the postsynaptic neuron. Here, we provide a molecular upgrade of the Beck and Eccles (...) model by identifying the quantum quasiparticles as Davydov solitons that twist the protein α-helices and trigger exocytosis of synaptic vesicles through helical zipping of the SNARE protein complex. We also calculate the observable probabilities for exocytosis based on the mass of this quasiparticle, along with the characteristics of the potential energy barrier through which tunneling is necessary. We further review the current experimental evidence in support of this novel bio-molecular model as presented. (shrink)

Against Nature – Chapter Abstracts Chapter 1. A Transdisciplinary Approach. In this short book you will find philosophy – metaphysical and political - economics, critical theory, complexity theory, ecology, sociology, journalism, and much else besides, along with the signposts and reference texts of the Information Systems field. Such transdisciplinarity is a challenge for both author and reader. Such books are often problematic: sections that are just old hat to one audience are by contrast completely new and difficult to another. (...) My hope is that in the interconnections, arguments and thrust of this polemic, readers will discover both interest and insight, alongside a range of new avenues to explore. This introductory chapter sets the scene – today’s digital world of Tech Giants and Fake News, its roots in the philosophical arguments of the 1920s, and the book’s key claims: (i) that the early 20th century philosophical grounding of today’s digital revolution is culpable in digital’s (growing) contribution to the ecological catastrophe unfolding in the 21st century; (ii) that process philosophy offers a new way to rethink that philosophical grounding, and reshape the digital revolution to support strategies to counter that catastrophe. Chapter 2. The Problem with Digital. This chapter begins with a brief overview of the research approaches in information systems as an academic field, before turning to the deeper roots of its malaise, in individualism, and its looming consequences. The three branches of Information Systems research, in academia, prove to be a useful lens through which to understand the field: Positivism, Interpretivism, and the Critical stance taken by this book. The ‘scientism’ at the root of positivism is examined, and the positivism in Information Systems critiqued as a historically contingent response to the ascendancy of a new brand of economics in Business Schools after the Second World War. But the computational market-fundamentalist form of economics sponsored in the 1950s (and applied by governments since the 1970s) centred around notions of the individual rational actor as an information processor. The philosophical underpinning of methodological and possessive individualism in this approach is exposed, and its influence upon the development – long before computing – of the science of ecology, and our notion of ecosystems, introduced. Chapter 3. The Future Does Not Exist. The philosophical core of the book, this chapter introduces process philosophy. Through an examination of the irreversible reality of subjectivity, Bergson’s famous notion of the durée reélle, and Whitehead’s critique of the bifurcation of subject and object, are introduced. The causally closed ‘time’ of positive science determines existence from the beginning to the end of the universe, be it three seconds or three trillion years. But the reality, of course, is that the future does not exist: our choices are real, and only one of myriad potential futures comes into being at each moment. As Bergson insists, durational succession exists, I am conscious of it; it is a fact. Bergson’s star – once the brightest of any living philosopher in the world – faded almost as quickly as it rose, under the onslaught from the logical positivists whose verificationism insisted that any proposition has no factual meaning if no evidence of observation can count for or against it: all ethics, aesthetics, romance, and metaphysics – and the very subjectivity with which duration is experienced - were thus closed down and dismissed. In this chapter it is reintroduced, to a new audience. Chapter 4. The World in a New Light. Many fundamental problems in the world can be seen as resulting from the false philosophy of bifurcation, fixity, and the reification of abstractions critiqued by process philosophy. Being – with all the isolation and focus upon the individual that it entails – must, if we are to address these problems, be seen as secondary to Becoming, with all the connection, interrelatedness, and complex collectivity that it implies. Choices become clearer, between positivism and interpretivism, between accents upon individualism or collectivism, between reductionist and complex adaptive systems approaches. The systemic individualism in Anglo-American societies can be regarded as actually harmful: the Tech Giants severing ties and bonds rather than connecting us; algebraic ecological models actually breaking the co-dependencies and co-requisites upon which real – complex - ecological health depends. Positivism, built as it is upon methodological individualism, seen in the light of process philosophy, becomes a danger to personal psychological balance – cutting us off from one another; a danger to the social fabric – undermining and impoverishing our civic life; and a danger to the ecological health of the planet – ignoring the immense (eco)systemic impact of our activities over the last centuries upon everything around us in the natural world. Chapter 5. A Theoretical Manifesto for Green IT. We are not islands, and in a process-relational social organisation much must be held in common. We are individuals, but we cannot survive alone. Four different perspectives on individualism show it to be little more than greed. An ecological economics reintegrating the household, the social, the supportive State, and – crucially – the life-giving earth into our polities is introduced and promoted. I introduce the concept of ‘Infomateriality’ – a non-bifurcated digital world where the physical bodies of people - fingers touching keyboards and eyes scanning screens - are as much ‘hardware’ as cabling, circuitboards and haptic interfaces, and the social practices, power relations, and embedded politics within IT artefacts define all such techné as fundamentally social. Abstract divisions are false, and whole, socially embedded systems should be the focus of IS, and from a philosophically and sociologically much deeper perspective. ‘Tech for Good’ is held up as movement in the right direction. My hope is that this book will help promote action, in the field of information systems, toward a better world, where Green Tech for Good is deployed for Nature, rather than against it. (shrink)

This report reviews what quantum physics and information theory have to tell us about the age-old question, How come existence? No escape is evident from four conclusions: (1) The world cannot be a giant machine, ruled by any preestablished continuum physical law. (2) There is no such thing at the microscopic level as space or time or spacetime continuum. (3) The familiar probability function or functional, and wave equation or functional wave equation, of standard quantum theory provide mere (...) continuum idealizations and by reason of this circumstance conceal the information-theoretic source from which they derive. (4) No element in the description of physics shows itself as closer to primordial than the elementary quantum phenomenon, that is, the elementary device-intermediated act of posing a yes-no physical question and eliciting an answer or, in brief, the elementary act of observer-participancy. Otherwise stated, every physical quantity, every it, derives its ultimate significance from bits, binary yes-or-no indications, a conclusion which we epitomize in the phrase, it from bit. (shrink)

This chapter provides a few approaches aiming to review the interpretation of matter, nature and the universe by trying to reframe the physical sciences in the context that has taken shape: arrangement, communication and information. In relation to what has just been presented, action regards more a mechanical type of physics with forces, arrangement, movements and orientations. Rational mechanics is the result. The existence of the two types of physics is associated with two great scientists. First of (...) all, Galileo, who established the principle of relativity and the addition of velocities by perfecting mathematical physics. Second, Planck, who elaborated the famous formula “E = hv” to account for blackbody radiation. If the distinction between a physics of communication and a physics of arrangement is applicable, then it must be validated in quantum theory and the description of the universe. Classical mechanics and relativistic cosmology describe arrangements of matter. Quantum physics describes communications. (shrink)
