    Disclosive computer ethics?John G. Messerly - 2007 - Acm Sigcas Computers and Society 37 (1):18-21.
    In his article "Disclosive Computer Ethics," Phillip Brey critiques mainstream computer ethics and argues for a disclosive computer ethic "which is concerned with the moral deciphering of embedded values and norms in computer systems, applications, and practices." 1 In this article I argue that DCE simply shifts the focus of MCE toward issues Brey deems important.

    Computer Ethics and Moral Methodology.Jeroen Van Den Hoven - 1997 - Metaphilosophy 28 (3):234-248.
    In computer ethics, as in other branches of applied ethics, the problem of the justification of moral judgment is still unresolved. I argue that the method which is referred to as “The Method of Wide Reflective Equilibrium” (WRE) offers the best solution to it. It does not fall victim to the false dilemma of having to choose either case‐based particularist or principle‐based universalist approaches to the problem of moral justification. I claim that WRE also provides the best (...)

    If computer ethics is to constitute a real engagement with industry and society that cultivates a genuine sensitivity to ethical concerns in the creation, development, and implementation of technologies, a genuine sensitivity that stands in marked contrast to ethics as “mere compliance,” then computer ethics will have to consist in issuing an open invitation to inquiry, since going beyond mere compliance requires a sensitivity to the importance of what we care about, and inquiry has the (...)

  8. Disclosive computer ethics.Philip Brey - 2000 - Acm Sigcas Computers and Society 30 (4):10-16.
    This essay provides a critique of mainstream computer ethics and argues for the importance of a complementary approach called disclosive computer ethics, which is concerned with the moral deciphering of embedded values and norms in computer systems, applications and practices. Also, four key values are proposed as starting points for disclosive studies in computer ethics: justice, autonomy, democracy and privacy. Finally, it is argued that research in disclosive computer ethics should be (...)

    Computer Ethics.John Weckert (ed.) - 2007 - Routledge.
    The study of the ethical issues related to computer use developed primarily in the 1980s, although a number of important papers were published in previous decades, many of which are contained in this volume. Computer ethics, as the field became known, flourished in the following decades. The emphasis initially was more on the computing profession: on questions related to the development of systems, the behaviour of computing professionals and so on. Later the focus moved to the Internet (...)

    There is growing consensus that teaching computer ethics is important, but there is little consensus on how to do so. One unmet challenge is increasing the capacity of computing students to make decisions about the ethical challenges embedded in their technical work. This paper reports on the design, testing, and evaluation of an educational simulation to meet this challenge. The privacy by design simulation enables more relevant and effective computer ethics education by letting students experience and (...)

    The Computer Ethics Dilemma.Marina Dedyulina - 2008 - Proceedings of the Xxii World Congress of Philosophy 48:87-95.
    New technology develops with little attention to its impact upon human values. In particular, let us do what we can in this era of “the computer revolution” to see that computer technology advances human values. True enough, we could argue endlessly over the meanings of terms like “privacy,” “health,” “security,” “fairness,” or “ownership.” Philosophers do it all the time – and ought to. But people understand such values well enough to desire and even to treasure them. We do (...)

    Computer ethics: The role of personal, informal, and formal codes. [REVIEW]Margaret Anne Pierce & John W. Henry - 1996 - Journal of Business Ethics 15 (4):425 - 437.
    Ethical decisions related to computer technology and computer use are subject to three primary influences: (1) the individual's own personal code (2) any informal code of ethical behavior that exists in the work place, and (3) exposure to formal codes of ethics. The relative importance of these codes, as well as factors influencing these codes, was explored in a nationwide survey of information system (IS) professionals. The implications of the findings are important to educators and employers in (...)

Paul Gibson, Stephane Maag, Francesco Agresta, Andrea Curley, Michael Collins & Dympna O’Sullivan - 2021 - International Journal of Ethics Education 7 (1):101-129.
    Within the Computer Science community, many ethical issues have emerged as significant and critical concerns. Computer ethics is an academic field in its own right and there are unique ethical issues associated with information technology. It encompasses a range of issues and concerns including privacy and agency around personal information, Artificial Intelligence and pervasive technology, the Internet of Things and surveillance applications. As computing technology impacts society at an ever growing pace, there are growing calls for more (...)

    Casuistry and computer ethics.Kari Gwen Coleman - 2007 - Metaphilosophy 38 (4):471-488.
    At the heart of the uniqueness debate is the possibility that the computer revolution may demand more in the way of ethical analysis than our traditional (that is, modern) ethical edification has prepared us for. In short, it may present new and unique problems and therefore demand new and unique solutions. In this article I argue that the solution is in fact an old and not‐so‐unique one: casuistry. Appealing to Jonsen and Toulmin's analysis of casuistry (1988), I argue that (...)

    In this essay, we demonstrate that the field of computer ethics shares many core similarities with two other areas of applied ethics, Academicians writing and teaching in the area of computer ethics, along with practitioners, must address ethical issues that are qualitatively similar in nature to those raised in medicine and business. In addition, as academic disciplines, these three fields also share some similar concerns. For example, all face the difficult challenge of maintaining a credible (...)

    In normative ethical theory, computer ethics belongs to the area of applied ethics dealing with practical and everyday moral problems arising from the use of computers and computer networks in the information society. Modern scholarship usually approves deontological and utilitarian ethics as appropriate to computer ethics, while classical theories of ethics, such as virtue ethics, are usually neglected as anachronistic and unsuitable to the information era and ICT industry. During past decades, (...)

    From machine ethics to computational ethics.Samuel T. Segun - 2021 - AI and Society 36 (1):263-276.
    Research into the ethics of artificial intelligence is often categorized into two subareas—robot ethics and machine ethics. Many of the definitions and classifications of the subject matter of these subfields, as found in the literature, are conflated, which I seek to rectify. In this essay, I infer that using the term ‘machine ethics’ is too broad and glosses over issues that the term computational ethics best describes. I show that the subject of inquiry of computational (...)

    The domain of “procedural ethics” is the set of reflective and deliberative methods that maximize the reliability of moral judgment. While no general algorithmic method exists that will guarantee the validity of ethical deliberation, non‐algorithmic “heuristic” methods can guide and inform the process, making it significantly more robust and dependable. This essay examines various representative heuristic procedures commonly recommended for use in applied ethics, maps them into a uniform set of twelve stages, identifies common faults, then shows how (...)

    Several context-specific social and political factors in Eastern and Central Europe are described — factors that must be considered while developing strategies to introduce Computer Ethics. Poland is used as a primary example. GNP per capita, the cost of hardware and software, uneven and scant distribution of computing resources, and attitudes toward work and authority are discussed. Such “geographical factors” must be taken into account as the new field of Computer Ethics develops.

    Issue Title: Moral Luck, Social Networking Sites, and Trust on the Web I argue that the problem of 'moral luck' is an unjustly neglected topic within Computer Ethics. This is unfortunate given that the very nature of computer technology, its 'logical malleability', leads to ever greater levels of complexity, unreliability and uncertainty. The ever widening contexts of application in turn lead to greater scope for the operation of chance and the phenomenon of moral luck. Moral luck bears (...)

  43. Is Computer Ethics Unique?Walter Maner - 1999 - Etica E Politica 1 (2).
    The rise of various unique, or uniquely transformed, ethical issues supports the claim that computer ethics deserves to be regarded as an academic field in its own right. Some of these issues are unique because they inherit the unique properties of the technology that generates or transforms them. When we are unable to resolve these issues through non-computer moral analogies, we are forced to discover new moral values, formulate new moral principles and develop new policies.

    An Aristotelian approach to understanding and teaching business ethics is presented and defended. The newly emerging field of computer ethics is also defined in an Aristotelian fashion, and an argument is made that this new field should be called “information ethics”. It is argued that values have their roots in the life and practices of a community; therefore, morality cannot be taught by training for a special way of reasoning.

    In this paper we have looked at some of the fundamental issues in computer ethics and the characteristics and specific problems of its constitution as a discipline. One of the important issues we have analysed is the problem of access (methods) to a number of new phenomena that have emerged as a result of the wider application of computer technology. Among other things, we pointed out the need to respect the ethical heritage and approach – as a (...)
