Could a computer have a mind? What kind of machine would this be? Exactly what do we mean by 'mind' anyway?The notion of the 'intelligent' machine, whilst continuing to feature in numerous entertaining and frightening fictions, has also been the focus of a serious and dedicated research tradition. Reflecting on these fictions, and on the research tradition that pursues 'Artificial Intelligence', raises a number of vexing philosophical issues. Minds and Computers introduces readers to these issues by offering an engaging, (...) coherent, and highly approachable interdisciplinary introduction to the Philosophy of Artificial Intelligence.Readers are presented with introductory material from each of the disciplines which constitute Cognitive Science: Philosophy, Neuroscience, Psychology, Computer Science, and Linguistics. Throughout, readers are encouraged to consider the implications of this disparate and wide-ranging material for the possibility of developing machines with minds. And they can expect to de. (shrink)

The fulcrum of this work is knowledge: what it is and how it is generated within the context of a capitalist society. First, Marx’s analysis of the objective labour process is extended to the mental labour process. Then, objective and mental labour processes are defined in terms of objective and mental transformations, with consideration paid to which of the two types of transformation is determinant. This requires a discussion of dialectical logic and formal logic. Within dialectical logic, two types of (...) processes are introduced: open ended and pre-determined. It is argued that computers (both traditional and quantum) and Artificial Intelligence cannot generate new knowledge, because they (a) rely on formal logic, i.e. they cannot engage in open-ended dialectical processes, and (b) are impervious to social determination. Connectedly, Artificial Intelligence systems such as ChatGPT cannot be a substitute for human thought or writing, because of the inevitability of ‘model collapse’. Next, focus is shifted to a specific form of knowledge: the ‘Copenhagen interpretation’ of quantum mechanics. It is shown that this interpretation is steeped in irrationalism and that it is a variant of pro-capitalist ideology. Finally, the social-historical roots of this ideology are revealed. (shrink)

One recursively enumerable real α dominates another one β if there are nondecreasing recursive sequences of rational numbers (a[n] : n ∈ ω) approximating α and (b[n] : n ∈ ω) approximating β and a positive constant C such that for all n, C(α − a[n]) ≥ (β − b[n]). See [R. M. Solovay, Draft of a Paper (or Series of Papers) on Chaitin’s Work, manuscript, IBM Thomas J. Watson Research Center, Yorktown Heights, NY, 1974, p. 215] and [G. J. (...) Chaitin, IBM J. Res. Develop., 21 (1977), pp. 350–359]. We show that every recursively enumerable random real dominates all other recursively enumerable reals. We conclude that the recursively enumerable random reals are exactly the Ω-numbers [G. J. Chaitin, IBM J. Res. Develop., 21 (1977), pp. 350–359]. Second, we show that the sets in a universal Martin-Lof test for randomness have random measure, and every recursively enumerable random number is the sum of the measures represented in a universal Martin-Lof test.

This book constitutes the strictly refereed post-workshop proceedings of the 11th International Workshop on Computer Science Logic, CSL '97, held as the 1997 Annual Conference of the European Association on Computer Science Logic, EACSL, in Aarhus, Denmark, in August 1997. The volume presents 26 revised full papers selected after two rounds of refereeing from initially 92 submissions; also included are four invited papers. The book addresses all current aspects of computer science logics and its applications and thus presents the state (...) of the art in the area. (shrink)

This article disrupts the logic of the “just-a-tool” argument, a powerful rhetorical device commonly offered as a rationale for using computers in education (and health care and other areas of society). Although this argument is articulated in many ways, its essence is the contention that computers are merely instructional tools, like blackboards or pencils, that can be used to enhance learning and therefore should be used in classrooms. The just-a-tool argument is difficult to challenge because it automatically constructs (...) counterarguments as illogical; they necessarily become arguments against using technology to improve the human condition. However, an analysis of the just-a-tool argument reveals that far from being logical and unassailable, it is both invalid and unsound. This “techno-illogic,” as the author calls it, arises when wisdom is subjugated to the dictates of technological “rationality,” and it is something that people must learn to recognize and defend against.

A true Turing machine requires an infinitely long paper tape. Thus a TM can be housed in the infinite world of Newtonian spacetime, but not necessarily in our world, because our world-at least according to our best spacetime theory, general relativity-may be finite. All the same, one can argue for the "existence" of a TM on the basis that there is no such housing problem in some other relativistic worlds that are similar to our world. But curiously enough-and this is (...) the main point of this paper-some of these close worlds have a special spacetime structure that allows TMs to perform certain Turing unsolvable tasks. For example, in one kind of spacetime a TM can be used to solve first-order predicate logic and the halting problem. And in a more complicated spacetime, TMs can be used to decide arithmetic. These new computers serve to show that Church's thesis is a thoroughly contingent claim. Moreover, since these new computers share the fundamental properties of a TM in ordinary operation, a computability theory based on these non-Turing computers is no less worthy of investigation than orthodox computability theory. Some ideas about this new mathematical theory are given. (shrink)

Computational neuroscientists not only employ computer models and simulations in studying brain functions. They also view the modeled nervous system itself as computing. What does it mean to say that the brain computes? And what is the utility of the ‘brain-as-computer’ assumption in studying brain functions? In previous work, I have argued that a structural conception of computation is not adequate to address these questions. Here I outline an alternative conception of computation, which I call the analog-model. The term ‘analog-model’ (...) does not mean continuous, non-discrete or non-digital. It means that the functional performance of the system simulates mathematical relations in some other system, between what is being represented. The brain-as-computer view is invoked to demonstrate that the internal cellular activity is appropriate for the pertinent information-processing task.Keywords: Computation; Computational neuroscience; Analog computers; Representation; Simulation.

Public policies designed to regulate the use of information technology to protect personal data have been based on different theoretical assumptions in different states, depending on whether the problem is defined in technological, civil libertarian, or bureaucratic terms. However, the rapid development, dispersal, and decentralization of information technology have facilitated a range of new surveillance practices that have in turn rendered the approaches of the 1960s and 1970s obsolete. The networking of the postindustrial state will require a reconceptualization of the (...) dynamic relationship between organizational practices and information technology and a more comprehensive appreciation of the privacy problem. With the call for the development of a more coherent information policy in a number of countries, there is evidence that policymakers have been taking this more holistic view. (shrink)

Could it be that Deleuze's most lasting legacy will lie in his ‘Postscript on Control Societies’, a mere 2,300-word essay from 1990? While he discussed computers and new media infrequently, Deleuze admittedly made contributions to the contemporary discourse on computing, cybernetics and networks, particularly in his late work. From the concepts of the rhizome and the virtual, to his occasional interjections on the digital versus the analogue, there is a case to be made that the late Deleuze has not (...) only influenced today's discourse on new media but also proposes an original set of arguments about society and politics at the turn of the new millennium. Focusing on the ‘Postscript on Control Societies’ and a handful of texts that surround it, we will reconstruct an image of what it means to live in the information age. This will have consequences for how we define the digital and the analogue, what the computer means, and ultimately provide some insight into one of the more elusive terms in all of Deleuze, the superfold.

Cognitive science has been dominated by the computational conception that cogniton is computation across representations. To the extent to which cognition is supposed to be a purposive, meaningful, algorithmic, problem-solving activity, however, computers appear to be incapable of cognition. They are devices that can facilitate computations on the basis of semantic grounding relations as special kinds of signs. Even their algorithmic, problem-solving character arises from ther interpretation by human users. Strictly speaking, computers as such–apart from human users–are not (...) only incapable of cognition but even incapable of computation, properly construed. If we want to understand the nature of thought, we are going to have to study thinking, not computing, because they are not the same thing. (shrink)

_Minds, Brains, Computers_ serves as both an historical and interdisciplinary introduction to the foundations of cognitive science.

A technological revolution with first order implications is undeniable and underway. That is the permeation of society by computers and telecommunications technology. For western society, committed to a social, economic, and value structure premised upon an industrial society, the move to an information society is more than disruptive; it is transformational. Current changes are so rapidly paced in relation to business planning that it creates major challenges and opportunities to reach out, influence, and guide the change.The telematics revolution will (...) affect every aspect of our society since it will affect every aspect of our world which involves the generation, production, storage, or handling of information. Many ethical issues are touched upon. To sum them up, the new immorality is to choose to act in ignorance of future consequences. (shrink)

This book provides a sustained and penetrating critique of a wide range of views in modern cognitive science and philosophy of the mind, from Turing's famous test for intelligence in machines to recent work in computational linguistic theory. While discussing many of the key arguments and topics, the authors also develop a distinctive analytic approach. Drawing on the methods of conceptual analysis first elaborated by Wittgenstein and Ryle, the authors seek to show that these methods still have a great deal (...) to offer in the field of the cognitive theory and the philosophy of mind, providing a powerful alternative to many of the positions put forward in the contemporary literature. Amoung the many issues discussed in the book are the following: the Cartesian roots of modern conceptions of mind; Searle's 'Chinese Room' thought experiment; Fodor's 'language of thought' hypothesis; the place of 'folk psychology' in cognitivist thought; and the question of whether any machine may be said to 'think' or 'understand' in the ordinary senses of these words. Wide ranging, up-to-date and forcefully argued, this book represents a major intervention in contemporary debates about the status of cognitive science an the nature of mind. It will be of particular interest to students and scholars in philosophy, psychology, linguistics and computing sciences. (shrink)

In 1839 the working hours of the computers employed on the lunar and planetary reductions of the Royal Observatory, Greenwich were reduced from eleven hours to eight hours. Previous historians have explained this decrease by reference to the generally benevolent nature of the manager of the reductions, George Biddell Airy. By contrast, this article uses the letters and notes exchanged between Airy and the computers to demonstrate that the change in the working hours originated from the computers (...) as a reaction to their poor working conditions. Through the exploration of these archival materials, the article shifts the focus of the analysis to the working experience of the computers, rather than to the administrative history of the project that inevitably tends to highlight Airy's actions. By doing so, the article shows how the computers were treated as a disposable low-skilled workforce, as opposed to aspiring astronomers with considerable mathematical talent. Through this reframing, the article takes a step towards a working history of the observatory. (shrink)

Within psychiatric research, the field of 'technotherapy' has been centred primarily on attempts to assess the computer as a treatment tool. The situation of daily clinical usage is, however, often ignored within such research, as for instance in controlled clinical trials. Our empirical study illustrates how health professionals and clients use different concepts of science and health in the attempts of formulating standards for using computers in psychiatric practice. The psychiatrists at a major psychiatric hospital decided and justified clients' (...) use of computers on the basis of a 'techno-medical' quality assurance. At the same hospital the occupational therapists stressed the improvement of social relations as a treatment goal. And, at a psychiatric outside clinic the clients used concepts of 'normality' for articulating quality in computer use. Our study exemplifies how the use of computers is a multifaceted 'performance'. What is called for is a kind of research not limited by artificial borders of 'the context' and the 'user-perspective'. In much humanistic research as well as in action research concepts of 'context' and 'user-perspective' imply a somehow romantic view on practice as pure and uncontaminated by the outside world contrasted to a 'general' or an 'objective' way of knowing the world. These sharp distinctions were however difficult to maintain in our study, where health professionals and clients took local contingencies into account when they interpreted computer use, while they simultaneously drew on a socio-historical reservoir of resources.

This article explores a new form of epistemic injustice related to computers and data mining in our interconnected world. I argue that data mining, as it is currently practiced, not only perpetuates but also contributes to a moral injustice primarily driven by economic factors. By employing Gaile Pohlhaus’s theoretical framework, the paper establishes criteria that classify data mining as a form of epistemic injustice (P1) and demonstrates its differentiation from other known forms in existing literature (P2). Through a comprehensive (...) analysis of data mining’s alignment with these criteria, the article highlights its unique nature and draws attention to its previously overlooked manifestation of epistemic injustice. By comparing data mining to established forms of epistemic injustice, this research underscores the urgent need for a critical examination of this ethical dilemma arising from technological advancements.

Open peer commentary on the article “Constructivism and Computation: Can Computer-Based Modeling Add to the Case for Constructivism?” by Manfred Füllsack. Upshot: While I do agree with Füllsack’s positive assessment of the use of computer simulations in advancing constructivism’s program, I am less convinced by the alleged opposition between computers and constructivism he builds up. In my opinion, his depiction of computers and computation is inaccurate in several respects. As a result, the alleged incompatibility with constructivism Füllsack objects (...) to disappears, and his whole essay could then be construed as a classic straw man fallacy. This is unfortunate, because it could lead to an unwarranted dismissal of his positive contribution. (shrink)

The federal and corporate initiative to technologize education has transformed schools, colleges, and universities into a new frontier for the computer industry. While educational institutions have maintained an equivocal relationship with markets and the state, they had striven to preserve a simulacrum of independence until the early 1980s. Then, neoconservative ideologies and their accompanying discourse on restructuring education discovered in the computer the ideal neutral tool to promote, in its virtual clothes, their gospel. The Clinton administration and big corporations, taking (...) advantage of the myth of the computer and the new vocabulary associated with computers, launched a massive program of wiring schools. The process, still unfolding at a rapid pace, poses grave problems for the teaching profession and the role of schools in society. The author argues that the unethical ways in which computers force their ways into many educational institutions, the values they embody, the contexts of their multiple usages, the hyperfragmentation and increasing commodification of knowledge that they cause through online education, the vocationalization of education, and the atomization of teachers are likely to shrink pedagogical and democratic possibilities both at local and global levels.

But especially I recall the fun we had when my father would read the horoscopes out loud and we’d compare them with the day’s events. Ours was a tough family for an astrologer to please, with rather different things happening to too many Aquarians, and a robust skepticism about anything of the sort later to be called “New Age.”How could I know that while we laughed and debated, somewhere else out there in the urban sprawl, Righter’s prognostications were being subjected to subtle and portentous analysis by that kingpin of the Frankfurt School, Theodor W. Adorno? Mirabile dictu, Adorno was living in L.A. at the time, and we now have his examination of Righter in The Stars Down to Earth, and Other Essays on the Irrational in Culture, edited with an excellent introduction by Stephen Crook (Routledge, $16.95). The result seems, now in the fullness of time, of mixed value and relevance. Adorno has produced an admirably accessible rhetoric of astrology, what he terms “content analysis.” In this, he is finding out for himself about the so-called cold-reading techniques of psychic consultation, practices long known to magicians and astrologers and only really understood by psychologists since Bertram Forer’s work in the 1940s. But beyond that, Adorno uses astrology to support and exemplify his theory of authoritarian irrationalism. As you might expect, this is more questionable. [End Page 424]To be sure, there are many intriguing observations throughout this mostly readable essay. In a passage perhaps even more true today than when it was written, Adorno says that a “climate of semi-erudition is the fertile breeding ground for astrology.” He refers to people who have gone just beyond the naive acceptance of the authority of science, but who don’t know enough, or who have not sufficiently developed “the power of thinking,” that they can replace such acceptance with anything better: “The semi-erudite vaguely wants to understand and is also driven by the narcissistic wish to prove superior to the plain people but he is not in a position to carry through complicated and detached intellectual operations.” In other words, quantum mechanics is pretty tough, but astrology offers sophisticated understanding of all reality in a few easy steps. Besides, astronomy is about those remote stars and planets out there—rather cold and impersonal. In Adorno’s apt title phrase, astrology brings it all down to earth, because it’s about the single most important thing in the universe: me. In an analogy that isn’t too far-fetched, he says that to the semi-erudite individual “astrology, just as other irrational creeds like racism, provides a short-cut by bringing the complex to a handy formula and offering at the same time the pleasant gratification that he who feels excluded from educational privileges nevertheless belongs to the minority of those who are ‘in the know.’” Someone once remarked that Scientology boosts self-esteem largely by giving semi-educated, degreeless persons impressive certificates to hang on their walls, and Adorno is right that there’s a similar syndrome at work with most New Age esoterica, including astrology. (In literary theory, there are no certificates, of course—you just have to learn the jargon.)Much to his credit, Adorno independently identifies many of the features of cold reading described by Forer and later writers, such as the persistent tendency of the client to personalize the general message. Of Righter’s “Follow up that intuition of yours,” or “Display that keen mind of yours,” Adorno says, “People who have any affinity at all to occultism are usually prepared to react to the information they are craving in such a way...

In 1976, Edward L. Robertson was part of a panel that discussed the overarching topic of Computers in Developing Nations. At the time, computers were slowly being introduced into mainstream society and thoughts of access or even use was the focus of many discussions. Today, not only has computers and its associated technology evolved but so too has the descriptor "developing nations". Since 1976, computers have moved from being desktops, to being portable and hand-held, thus becoming (...) extremely accessible to the general public. In the same vein, the classification of a country's development has since been modified to include another category --- the emerging market. This newly defined category delineates nations that have rapidly growing societies or business markets from those that are still slowly growing. The participants' contributing to this article are all from countries that are identified by the International Monetary Fund as being either an emerging market or a developing country. Another Non-Governmental Organization, the World Bank only recognizes Oman as being a developed country. To follow the [previous] panels' discussion on the importance of computers in developing nations some questions were revisited and new ones were introduced to provide an up-to-date view of computers as seen by specific countries.

This book is designed to make accessible to nonspecialists the still evolving concepts of quantum mechanics and the terminology in which these are expressed. The opening chapters summarize elementary concepts of twentieth century quantum mechanics and describe the mathematical methods employed in the field, with clear explanation of, for example, Hilbert space, complex variables, complex vector spaces and Dirac notation, and the Heisenberg uncertainty principle. After detailed discussion of the Schrödinger equation, subsequent chapters focus on isotropic vectors, used to construct (...) spinors, and on conceptual problems associated with measurement, superposition, and decoherence in quantum systems. Here, due attention is paid to Bell's inequality and the possible existence of hidden variables. Finally, progression toward quantum computation is examined in detail: if quantum computers can be made practicable, enormous enhancements in computing power, artificial intelligence, and secure communication will result. This book will be of interest to a wide readership seeking to understand modern quantum mechanics and its potential applications. (shrink)

In this reply to James H. Fetzer’s “Minds and Machines: Limits to Simulations of Thought and Action”, I argue that computationalism should not be the view that (human) cognition is computation, but that it should be the view that cognition (simpliciter) is computable. It follows that computationalism can be true even if (human) cognition is not the result of computations in the brain. I also argue that, if semiotic systems are systems that interpret signs, then both humans and computers (...) are semiotic systems. Finally, I suggest that minds can be considered as virtual machines implemented in certain semiotic systems, primarily the brain, but also AI computers. In doing so, I take issue with Fetzer’s arguments to the contrary. (shrink)
