Search engines play an increasingly pivotal role in the distribution and eventual construction of knowledge, yet they are largely unnoticed, their procedures are opaque, and they are almost completely devoid of independent oversight. In this paper the author examines three areas in which we encounter difficult and persistent ethical issues in search engine technology: The problem of algorithm and the lack of transparency of the search process, the problem of privacy with regards of the possibility to monitor search histories, and (...) the problem of local censorship. The given findings lead to the conclusion that the development of structures of accountability for search engines is an important task for the near future. (shrink)

An award-winning theoretical physicist and best-selling author of A Universe from Nothing traces the dramatic discovery of the counterintuitive world of reality, explaining how readers can shift their perspectives to gain greater understandings of our individual roles in the universe.

ETHICS: A PLURALISTIC APPROACH TO MORAL THEORY, FIFTH EDITION provides a comprehensive yet clear introduction to the main traditions in ethical thought, including virtue ethics, utilitarianism, and deontology. Additionally, the book presents a conceptual framework of ethical pluralism to help students understand the relationship among various theories. Lawrence Hinman, one of today's most respected and accomplished educators in ethics and philosophy education, presents a text that gives students plentiful opportunities to explore ethical theory and their own responses to them, (...) using fascinating features such as the Ethical Inventory sections that appear at the beginning and the end of the text. End-of-chapter discussion questions, and the use of current issues and movies help students retain what they've learned and truly comprehend the subject matter.

I propose that primary conscious awareness arises from synchronized activity in dendrites of neurons in dorsal thalamic nuclei, mediated particularly by inhibitory interactions with thalamic reticular neurons. In support, I offer four evidential pillars: consciousness is restricted to the results of cortical computations; thalamus is the common locus of action of brain injury in vegetative state and of general anesthetics; the anatomy and physiology of the thalamus imply a central role in consciousness; neural synchronization is a neural correlate of consciousness.

Wikipedia has challenged traditional notions about the roles of experts in the Internet Age. Section 1 sets up a paradox. Wikipedia is a striking popular success, and yet its success can be attributed to the fact that it is wide open and bottom-up. How can such a successful knowledge project disdain expertise? Section 2 discusses the thesis that if Wikipedia could be shown by an excellent survey of experts to be fantastically reliable, then experts would not need to be granted (...) positions of special authority. But, among other problems, this thesis is self-stultifying. Section 3 explores a couple ways in which egalitarian online communities might challenge the occupational roles or the epistemic leadership roles of experts. There is little support for the notion that the distinctive occupations that require expertise are being undermined. It is also implausible that Wikipedia and its like might take over the epistemic leadership roles of experts. Section 4 argues that a main reason that Wikipedia’s articles are as good as they are is that they are edited by knowledgeable people to whom deference is paid, although voluntarily. But some Wikipedia articles suffer because so many aggressive people drive off people more knowledgeable than they are; so there is no reason to think that Wikipedia’s articles will continually improve. Moreover, Wikipedia’s commitment to anonymity further drives off good contributors. Generally, some decisionmaking role for experts is not just consistent with online knowledge communities being open and bottom-up, it is recommended as well. (shrink)

Corpus linguistics is becoming a respected method of statutory and constitutional interpretation in the United States over the past decade, yet it has also generated a backlash from a group of scholars that engage in empirical work. This essay attempts to demonstrate both the contributions and the risks of using linguistic corpora as a primary tool in legal interpretation. Its legitimacy stems from the fact that courts routinely state that statutory terms, when not defined as a matter of law, are (...) to be given their ordinary meaning. Judges have responded to this challenge, with the assistance of the linguistics community, by using corpora to determine which meanings are ordinary. However, legal analysts have not determined exactly what makes one meaning ordinary and another not ordinary. This gap has led to a level of disagreement in the field. Moreover, while linguists who engage in corpus linguistic analysis typically emphasize the importance of context, the legal application is peculiarly context-free, in keeping with legal philosophies that eschew reliance on reference to a law’s purpose and the intent of the legislature that enacted it. This move adds a political dimension to corpus analysis as a means of legal interpretation. Yet, the article concludes that by relying on a blend of general and specialized corpora, the legal system can substantially reduce the problem of contextualization, as some linguists and practitioners have already recognized.

Rarely has a philosopher demanded such a purity of moral motives. Even when he discusses those “many spirits of so sympathetic a temper that, without any further motive of vanity or self-interest, they find an inner pleasure in spreading happiness around them and can take delight in the contentment of others as their own work,” Kant maintains that, “in such a case an action of this kind, however right and however amiable it may be, still has no genuinely moral worth.” (...) Because the action is done from inclination rather than duty, it cannot qualify as a morally good action in Kant’s eyes. Indeed, this seems to suggest that from a moral point of view the person who is naturally unsympathetic to others almost has an advantage, at least in terms of the opportunity for moral action, over those who are naturally inclined to altruistic acts. Kant hardly seems to shrink from such a conclusion. His own words best convey his position here. (shrink)

The essay is an attempt to examine aspects of legal interpretation from an external, sociological point of view. “Interpretation”, in its normal juristic sense, is primarily a process in which decision‐makers with secondary legitimacy link their decisions to authority of primary legitimacy. The type of legitimacy which is dominant within the legal system greatly influences the style of interpretation ‐ in “closed” systems, where the stock of premises is fixed, “legalism” will abound. Legal interpretation is not concerned with what a (...) text really means, in any literal sense; and standards for judging legal interpretation are different from the standards of judging other forms of communication, for example, literature. Indeed, a judge can be considered great precisely because of his creative acts of misinterpretation. (shrink)

Shepard proposes that the human mind relies on screw displacement because of its adaptive simplicity and uniqueness. I discuss this hypothesis by assessing screw displacement with respect to (1) other plausible spatial transformations, (2) a variety of criteria for adaptive efficiency and utility, and (3) a variety of psychological conditions in which observed responses discriminate amongst alternative spatial procedures.

During development, large numbers of cells die by a process known as programmed cell death. This loss of cells plays a number of important roles, including the sculpting of the body form and the removal of vestigial tissues. Data obtained from a variety of organisms has suggested that a cell's ‘decision’ to die is a differentiative event, requiring the activation of specific sets of genes. Several putative ‘cell death’ genes have recently been cloned, and one has been identified as the (...) product of the polyubiquitin gene. Accumulation of ubiquitin has been observed not only during programmed cell death, but also in several neurodegenerative disorders, including Alzheimer's Disease. (shrink)
