I propose to consider the question, "Can machines think?" This should begin with definitions of the meaning of the terms "machine" and "think." The definitions might be framed so as to reflect so far as possible the normal use of the words, but this attitude is dangerous, If the meaning of the words "machine" and "think" are to be found by examining how they are commonly used it is difficult to escape the conclusion that the meaning and the answer to (...) the question, "Can machines think?" is to be sought in a statistical survey such as a Gallup poll. But this is absurd. Instead of attempting such a definition I shall replace the question by another, which is closely related to it and is expressed in relatively unambiguous words. The new form of the problem can be described in terms of a game which we call the 'imitation game." It is played with three people, a man (A), a woman (B), and an interrogator (C) who may be of either sex. The interrogator stays in a room apart front the other two. The object of the game for the interrogator is to determine which of the other two is the man and which is the woman. He knows them by labels X and Y, and at the end of the game he says either "X is A and Y is B" or "X is B and Y is A." The interrogator is allowed to put questions to A and B. We now ask the question, "What will happen when a machine takes the part of A in this game?" Will the interrogator decide wrongly as often when the game is played like this as he does when the game is played between a man and a woman? These questions replace our original, "Can machines think?". (shrink)

The essential difficulty about Computer Ethics' (CE) philosophical status is a methodological problem: standard ethical theories cannot easily be adapted to deal with CE-problems, which appear to strain their conceptual resources, and CE requires a conceptual foundation as an ethical theory. Information Ethics (IE), the philosophical foundational counterpart of CE, can be seen as a particular case of environmental ethics or ethics of the infosphere. What is good for an information entity and the infosphere in general? This is the ethical (...) question asked by IE. The answer is provided by a minimalist theory of deseerts: IE argues that there is something more elementary and fundamental than life and pain, namely being, understood as information, and entropy, and that any information entity is to be recognised as the centre of a minimal moral claim, which deserves recognition and should help to regulate the implementation of any information process involving it. IE can provide a valuable perspective from which to approach, with insight and adequate discernment, not only moral problems in CE, but also the whole range of conceptual and moral phenomena that form the ethical discourse.

Computational and information‐theoretic research in philosophy has become increasingly fertile and pervasive, giving rise to a wealth of interesting results. In consequence, a new and vitally important field has emerged, the philosophy of information (PI). This essay is the first attempt to analyse the nature of PI systematically. PI is defined as the philosophical field concerned with the critical investigation of the conceptual nature and basic principles of information, including its dynamics, utilisation, and sciences, and the elaboration and application of (...) information‐theoretic and computational methodologies to philosophical problems. I argue that PI is a mature discipline for three reasons: it represents an autonomous field of research; it provides an innovative approach to both traditional and new philosophical topics; and it can stand beside other branches of philosophy, offering a systematic treatment of the conceptual foundations of the world of information and the information society.

The philosophy of information (PI) is a new area of research with its own field of investigation and methodology. This article, based on the Herbert A. Simon Lecture of Computing and Philosophy I gave at Carnegie Mellon University in 2001, analyses the eighteen principal open problems in PI. Section 1 introduces the analysis by outlining Herbert Simon's approach to PI. Section 2 discusses some methodological considerations about what counts as a good philosophical problem. The discussion centers on Hilbert's famous analysis (...) of the central problems in mathematics. The rest of the article is devoted to the eighteen problems. These are organized into five sections: problems in the analysis of the concept of information, in semantics, in the study of intelligence, in the relation between information and nature, and in the investigation of values.

The paper outlines a new interpretation of informational privacy and of its moral value. The main theses defended are: (a) informational privacy is a function of the ontological friction in the infosphere, that is, of the forces that oppose the information flow within the space of information; (b) digital ICTs (information and communication technologies) affect the ontological friction by changing the nature of the infosphere (re-ontologization); (c) digital ICTs can therefore both decrease and protect informational privacy but, most importantly, they (...) can also alter its nature and hence our understanding and appreciation of it; (d) a change in our ontological perspective, brought about by digital ICTs, suggests considering each person as being constituted by his or her information and hence regarding a breach of one’s informational privacy as a form of aggression towards one’s personal identity.

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)

Agents require a constant flow, and a high level of processing, of relevant semantic information, in order to interact successfully among themselves and with the environment in which they are embedded. Standard theories of information, however, are silent on the nature of epistemic relevance. In this paper, a subjectivist interpretation of epistemic relevance is developed and defended. It is based on a counterfactual and metatheoretical analysis of the degree of relevance of some semantic information i to an informee/agent a, as (...) a function of the accuracy of i understood as an answer to a query q, given the probability that q might be asked by a. This interpretation of epistemic relevance vindicates a strongly semantic theory of information, according to which semantic information encapsulates truth. It accounts satisfactorily for several important applications and interpretations of the concept of relevant information in a variety of philosophical areas. And it interfaces successfully with current philosophical interpretations of causal and logical relevance. (shrink)

This paper traces the application of information theory to philosophical problems of mind and meaning from the earliest days of the creation of the mathematical theory of communication. The use of information theory to understand purposive behavior, learning, pattern recognition, and more marked the beginning of the naturalization of mind and meaning. From the inception of information theory, Wiener, Turing, and others began trying to show how to make a mind from informational and computational materials. Over the last 50 years, (...) many philosophers saw different aspects of the naturalization of the mind, though few saw at once all of the pieces of the puzzle that we now know. Starting with Norbert Wiener himself, philosophers and information theorists used concepts from information theory to understand cognition. This paper provides a window on the historical sequence of contributions made to the overall project of naturalizing the mind by philosophers from Shannon, Wiener, and MacKay, to Dennett, Sayre, Dretske, Fodor, and Perry, among others. At some time between 1928 and 1948, American engineers and mathematicians began to talk about `Theory of Information' and `Information Theory,' understanding by these terms approximately and vaguely a theory for which Hartley's `amount of information' is a basic concept. I have been unable to find out when and by whom these names were first used. Hartley himself does not use them nor does he employ the term `Theory of Transmission of Information,' from which the two other shorter terms presumably were derived. It seems that Norbert Wiener and Claude Shannon were using them in the Mid-Forties. (shrink)

There are many ways of understanding the nature of philosophical questions. One may consider their morphology, semantics, relevance, or scope. This article introduces a different approach, based on the kind of informational resources required to answer them. The result is a definition of philosophical questions as questions whose answers are in principle open to informed, rational, and honest disagreement, ultimate but not absolute, closed under further questioning, possibly constrained by empirical and logico-mathematical resources, but requiring noetic resources to be answered. (...) The article concludes with a discussion of some of the consequences of this definition for a conception of philosophy as the study (or “science”) of open questions, which uses conceptual design to analyse and answer them.

A global information ethics that seeks to avoid imperialistic homogenization must conjoin shared norms while simultaneously preserving the irreducible differences between cultures and peoples. I argue that a global information ethics may fulfill these requirements by taking up an ethical pluralism – specifically Aristotle’s pros hen [“towards one”] or “focal” equivocals. These ethical pluralisms figure centrally in both classical and contemporary Western ethics: they further offer important connections with the major Eastern ethical tradition of Confucian thought. Both traditions understand ethical (...) judgment to lead to and thus require ethical pluralism – i.e., an acceptance of more than one judgment regarding the interpretation and application of a shared ethical norm. Both traditions invoke notions of resonance and harmony to articulate pluralistic structures of connection alongside irreducible differences. Specific examples within Western computer and information ethics demonstrate these pluralisms in fact working in praxis. After reviewing further resonances and radical differences between Western and Eastern views, I then argue that emerging conceptions of privacy and data privacy protection laws in China, Hong Kong, Japan, and Thailand in fact constitute a robust, pros hen pluralism with Western conceptions. In both theory and in praxis, then, this pluralism thus fulfills the requirement for a global information ethics that holds shared norms alongside the irreducible differences between cultures and peoples.

This paper deals with intercultural aspects of privacy, particularly with regard to differences between Japanese and Western conceptions. It starts with a reconstruction of the genealogy of Western subjectivity and human dignity as the basic assumptions underlying Western views on privacy. An analysis of the Western concept of informational privacy is presented. The Japanese topic of ‘‘denial of self” (Musi) as well as the concepts of Seken, Shakai and Ikai (as analyzed by the authors of the companion piece on privacy (...) in Japan) give rise to intercultural comparisons. The paper addresses the question of privacy in cyberspace and mass media. Finally the question of freedom of speech is related to the Japanese concepts of Ohyake and Watakusi. (shrink)

The paper presents, firstly, a brief review of the long history\nof information ethics beginning with the Greek concept of parrhesia\nor freedom of speech as analyzed by Michel Foucault. The recent concept\nof information ethics is related particularly to problems which arose\nin the last century with the development of computer technology and\nthe internet. A broader concept of information ethics as dealing\nwith the digital reconstruction of all possible phenomena leads to\nquestions relating to digital ontology. Following Heidegger{\textquoteright}s\nconception of the relation between ontology and metaphysics, (...) the\nauthor argues that ontology has to do with Being itself and not just\nwith the Being of beings which is the matter of metaphysics. The\nprimary aim of an ontological foundation of information ethics is\nto question the metaphysical ambitions of digital ontology understood\nas today{\textquoteright}s pervading understanding of Being. The\nauthor analyzes some challenges of digital technology, particularly\nwith regard to the moral status of digital agents. The author argues\nthat information ethics does not only deal with ethical questions\nrelating to the infosphere. This view is contrasted with arguments\npresented by Luciano Floridi on the foundation of information ethics\nas well as on the moral status of digital agents. It is argued that\na reductionist view of the human body as digital data overlooks the\nlimits of digital ontology and gives up one basis for ethical orientation.\nFinally issues related to the digital divide as well as to intercultural\naspects of information ethics are explored {\textendash} and long\nand short-term agendas for appropriate responses are presented.

PurposeThe purpose of this paper is to attempt to resolve some unclarity about the nature and character of intercultural information ethics (IIE).Design/methodology/approachBy survey of some of the relevant literature, the paper identifies and explains the distinctive projects of IIE. In addition, to facilitate the achievement of these projects, the paper attempts to identify the most fruitful metaphysical and meta‐ethical assumptions about truth and moral truth. In particular, to identify and determine which of objectivist theories of truth and morality or intersubjectivist (...) theories of truth and morality provides a better theoretical foundation for IIE.FindingsTwo projects are identified: a descriptive project and a normative project. It is argued that moral objectivism provides a better foundation for the normative (project than moral intersubjectivism (or, as it is sometimes called, normative cultural relativism) in the sense that objectivism provides a more solid ground for the principle grounding the normative project – namely that agreement among cultures on principles of information ethics is good or desirable. In other respects, it is concluded that moral objectivism and moral intersubjectivism do equally well in grounding the normative project.Originality/valueThe paper is the first to compare the two methodological approaches and points in the direction of the most fruitful approach to take in pursuing IIE.

This special issue of Minds and Machines contains a number of responses to Luciano Floridi’s groundbreaking Philosophy of Information (Oxford 2011). The essays contained here have been grouped by topic; essays 1–5 concern epistemological features of Floridi’s approach, and essays 6–8 address his metaphysics.In “On Floridi’s Method of Levels ofion”, Jan van Leeuwen addresses Floridi’s operational definition of a level of abstraction. Emphasizing the link between Floridi’s notion of abstraction and that used in computer science, van Leeuven notes that the (...) method of levels of abstraction may require supplementation in the form of annotation. Annotations, which exist “outside” the formal limits of the levels of abstraction to which they are attached, specify what perspective should be taken towards those levels. Annotations so understood both facilitate the expression of semantic information and elucidate the relationship between levels of abstraction. van Leeuwen then uses a case. (shrink)
