Contemporary discussions of information overload have important precedents during the years 1550-1750. An examination of the early modern period in Europe, including work of humanism, science, theology, and popular encyclopedias demonstrates that perceptions of information overload have as much to do with the ways in which knowledge is represented as with any quantitative measurers in the production of new texts, ideas, or facts. Key figures in this account include Francis Bacon, Conrard Gesner, Francesco Sacchini, Johann Heinrich Alsted, Casoar Bauhin, Rempert (...) Dodeones, Samuel Bochrt, Johann Jakob Scheuchzer, John Wilkins, Jonathan Swift, Ephraim Chambers, Smauel Johnson, Denis Diderot, and Louis-Sébastian Mercier. (shrink)

This paper evaluates and criticises the developmental systems conception of evolution and develops instead an extension of the gene's eye conception of evolution. We argue (i) Dawkin's attempt to segregate developmental and evolutionary issues about genes is unsatisfactory. On plausible views of development it is arbitrary to single out genes as the units of selection. (ii) The genotype does not carry information about the phenotype in any way that distinguishes the role of the genes in development from that other factors. (...) (iii) There is no simple and general causal criterion which distinguishes the role of genes in development and evolution. (iv) There is, however, an important sense in which genes but not every other developmental factor represent the phenotype. (v) The idea that genes represent features of the phenotype forces us to recognise that genes are not the only, or almost the only, replicators. Many mechanisms of replication are involved in both development and evolution. (vi) A conception of evolutionary history which recognises both genetic and non-genetic replicators, lineages of replicators and interactors has advantages over both the radical rejection of the replicator/interactor distinction and the conservative restriction of replication to genetic replication.

The use of informational terms is widespread in molecular and developmental biology. The usage dates back to Weismann. In both protein synthesis and in later development, genes are symbols, in that there is no necessary connection between their form (sequence) and their effects. The sequence of a gene has been determined, by past natural selection, because of the effects it produces. In biology, the use of informational terms implies intentionality, in that both the form of the signal, and the response (...) to it, have evolved by selection. Where an engineer sees design, a biologist sees natural selection. (shrink)

This paper outlines a quantitative theory of strongly semantic information (TSSI) based on truth-values rather than probability distributions. The main hypothesis supported in the paper is that the classic quantitative theory of weakly semantic information (TWSI), based on probability distributions, assumes that truth-values supervene on factual semantic information, yet this principle is too weak and generates a well-known semantic paradox, whereas TSSI, according to which factual semantic information encapsulates truth, can avoid the paradox and is more in line with the (...) standard conception of what generally counts as semantic information. After a brief introduction, section two outlines the semantic paradox implied by TWSI, analysing it in terms of an initial conflict between two requisites of a quantitative theory of semantic information. In section three, three criteria of semantic information equivalence are used to provide a taxonomy of quantitative approaches to semantic information and introduce TSSI. In section four, some further desiderata that should be fulfilled by a quantitative TSSI are explained. From section five to section seven, TSSI is developed on the basis of a calculus of truth-values and semantic discrepancy with respect to a given situation. In section eight, it is shown how TSSI succeeds in solving the paradox. Section nine summarises the main results of the paper and indicates some future developments. (shrink)

Luciano Floridi (2003) offers a theory of information as a strongly semantic notion, according to which information encapsulates truth, thereby making truth a necessary condition for a sentence to qualify as information. While Floridi provides an impressive development of this position, the aspects of his approach of greatest philosophical significance are its foundations rather than its formalization. He rejects the conception of information as meaningful data, which entails at least three theses – that information can be false; that tautologies are (...) information; and, that It is true that ... is non-redundant – appear to be defensible. This inquiry offers various logical, epistemic, and ordinary-language grounds to demonstrate that an account of his kind is too narrow to be true and that its adoption would hopelessly obscure crucial differences between information, misinformation, and disinformation.

The distinction between misinformation and disinformation becomes especially important in political, editorial, and advertising contexts, where sources may make deliberate efforts to mislead, deceive, or confuse an audience in order to promote their personal, religious, or ideological objectives. The difference consists in having an agenda. It thus bears comparison with lying, because lies are assertions that are false, that are known to be false, and that are asserted with the intention to mislead, deceive, or confuse. One context in which disinformation (...) abounds is the study of the death of JFK, which I know from more than a decade of personal research experience. Here I reflect on that experience and advance a preliminary theory of disinformation that is intended to stimulate thinking on this increasingly important subject. Five kinds of disinformation are distinguished and exemplified by real life cases I have encountered. It follows that the story you are about to read is true. (shrink)

This essay examines the ways in which dead bodies were transformed by traditional Chinese forensic methodology into objects of postmortem examination during the Qing dynasty. The Qing authorities implemented various devices to standardize not only the forensic examination as an administrative procedure but also the cognitive activities involved, such as corpse observation, wound interpretation, and transcription. The essay argues that these devices, such as the official forensic manual, formalized documents, and strict norms of documenting, were constituents of a specific pattern (...) of perception that normalized the ways in which a corpse should be regarded and understood so as to bear forensic significance. Although this pattern of perception led to a rigid vision of crimes and the consequent corporeal damage, it enabled forensic reasoning to function like an operational procedure, which presented certain advantages with regard to the particular legal culture of the Qing era.

This article investigates the various forces that may help to explain the ongoing historio-graphical phenomenon of revision. It takes as its point of departure Michel de Certeau's understanding of the writing of history as a process consisting of an unstable and constantly changing triangulated relationship among a place , analytical procedures , and the construction of a text . For de Certeau, revision is the formal prerequisite for writing history because the very distance between past and present requires continuous innovation (...) simply to produce the objects of historical knowledge, which have no existence apart from the historian's identification of them. The specific nature of revision at a given moment is determined by the specificities of the process as a whole, that is, by the characteristics of place, procedure, and text and their contemporary relational configuration.Taking the rise of "linguistic-turn" historiography as exemplary of the process of historical revision in its broadest possible meaning, the article seeks to discover the possible "causes" for that turn. It begins with an analysis of the psychological roots of poststructuralism as a response to the holocaust and its aftermath, and then proceeds to explore the possible economic and social transformations in the postwar world that might account for its reception, both in Europe but also, more counterintuitively, in the United States, where postmodernism proved to have an especially strong appeal. Added to this mix are the new patterns of social recruitment into the historical profession in the "sixties." the essay suggests that, to the extent that revision is understood as the result of the combined effect of psychological, social, and professional determinations, it is unlikely that there will ever be genuine consensus about the sources of revision in history, since all historians bring to their work differing congeries of psychological preoccupations, social positions, and professional commitments.

There is no consensus yet on the definition of semantic information. This paper contributes to the current debate by criticising and revising the Standard Definition of semantic Information (SDI) as meaningful data, in favour of the Dretske‐Grice approach: meaningful and well‐formed data constitute semantic information only if they also qualify as contingently truthful. After a brief introduction, SDI is criticised for providing necessary but insufficient conditions for the definition of semantic information. SDI is incorrect because truth‐values do not supervene on (...) semantic information, and misinformation (that is, false semantic information) is not a type of semantic information, but pseudo‐information, that is not semantic information at all. This is shown by arguing that none of the reasons for interpreting misinformation as a type of semantic information is convincing, whilst there are compelling reasons to treat it as pseudo‐information. As a consequence, SDI is revised to include a necessary truth‐condition. The last section summarises the main results of the paper and indicates some interesting areas of application of the revised definition. (shrink)

Narrative as it is used by historians is not merely an incidental, stylistic feature of the historian's craft, but essential to historical explanation. Narrative presupposes a world of things that endure through change. Stories fill in the gaps in our experience and thus make continuity visible. Ideally, narrative stands proxy for experience, though this ideal can never be attained. No criterion can be formulated that will signify when a story is complete enough. The changing perspective of the historian and the (...) infinite detail with which he has to deal makes his task a continuous one. Yet the historian cannot be radically subjective because his story is always limited by the chronology of his events and the accuracy of his details. The rationale of narrative enables the historian to repudiate the covering-law model of historical explanation. (shrink)

The Swedish naturalist Carl Linnaeus is famous for having turned botany into a systematic discipline, through his classification systems—most notably the sexual system—and his nomenclature. Throughout his life, Linnaeus experimented with various paper technologies designed to display information synoptically. The list took pride of place among these and is also the common element of more complex representations he produced, such as genera descriptions and his “natural system.” Taking clues from the anthropology of writing, this essay seeks to demonstrate that lists (...) can be considered as genuine research technologies. They possess a potential to generate research problems of their own but also pose limitations to inquiries that can be overcome only by the use of new media. (shrink)
