I contend that in the "meditations" descartes expresses both certainty and doubt that he exists. He is certain that he exists when he views himself in terms of occurrent acts of thinking; his certainty stems from his "observing" such acts. When he views himself in terms of an "unobservable" thinking substance, The belief that acts are in a thinking substance is central. Thinking substances can be known to exist only by demonstrating that this belief is true, And the demonstration can (...) only be accomplished by showing that a good God exists. Thus prior to such proofs, Descartes can doubt that he, Qua particular thinking substance, Exists. He does exhibit self-Doubt in the third meditation. (shrink)

Arnauld charged descartes with circularity in his theological proof. I argue that descartes's system is circular. Then I discuss how descartes responds to this problem. He develops distinctions which only seem to allay the circularity charge. Ironically, It is descartes himself, By means of his insistence on the idea-Thing distinction and attendant doubts, And his insistence on 'doubting the indubitable', Who highlights the chronic difficulties of the theological proofs.

My aim is to call attention to two features of Descartes' presentation of his so-called criterion of truth in the third meditation. First, there is an explicit shift between "clear and distinct "perception"" and "clear and distinct "conception"." Second, in the two paragraphs which follow the presentation of the criterion, Descartes proceeds to highlight a correlative distinction. Roughly speaking, the distinction is between perceiving something and having "persuasive" conceptions of something. This distinction not only corresponds to the shift between "perceive" (...) and "conceive" but also to the claims about which Descartes is certain and doubtful, respectively, prior to the proofs about God's existence. Thus the verbal shift is not merely that; it also signals a substantive distinction central to the "Meditations". (shrink)

Alzheimer's disease results from the degeneration of neurons. Degenerating nerve cells express atypical proteins, and amyloid is deposited. We suggest that some of these events are strongly influenced by genetic factors and age. Animal models should be useful in investigating the pathogenic mechanisms that lead to the brain abnormalities seen in this disease.

Empiricism is historically, even if not logically, connected with racism. Some of empiricism's primary proponents were racists. Rationalism provides a "modest conceptual barrier" to racism. These are the main theses of Bracken's collection of essays. One sees immediately that Bracken wishes to move a classical and allegedly purely philosophical debate into the ideological arena.

The study examines the relationship between the strength of an organizationÕs ethical climate and ethical problems involving human resource management. Data were collected through a survey of 1078 human resource managers. The results indicate a statistically significant negative relationship between the strength of an organization'ss ethical climate and the seriousness of ethical violations and a statistically significant positive relationship between an organization'ss ethical climate and success in responding to ethical issues. Thus, interventions that strengthen an organization'ss ethical climate may help (...) manage ethical behavior within organizations. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Mismapping the Underworld: Daring and Error in Dante’s ‘Comedy’Edward Donald KennedyMismapping the Underworld: Daring and Error in Dante’s ‘Comedy,’ by John Kleiner; 182 pp. Stanford: Stanford University Press, 1994, $32.50.Critics once emphasized the unity and apparent perfection of Dante’s Divine Comedy. In Mismapping the Underworld, John Kleiner emphasizes instead the imperfections, the inconsistencies, and inaccuracies in Dante’s work both to give a more accurate assessment of (...) Dante’s artistry and, as he remarks, to help readers “learn to enjoy” the imperfections (p. 2).The five chapters of the book are devoted to various cruces in the Vita nuova and the Comedy. The first chapter considers numerology in the Vita nuova: pointing out that scholars’ arguments for that work’s numerological symmetry have been flawed, Kleiner asks if Dante had as much “passion for order” as scholars have assumed. The second chapter, from which the title of the book is taken, considers earlier scholars’ attempts to draw accurate maps of Dante’s vision of Hell and inaccuracies and inconsistencies in that vision. Probably not many readers, for example, have realized that Satan, partially buried in the ice of Cocytus at the bottom of Hell, must be about 2,500 feet tall, if one calculates his height from the evidence Dante has given us, and even the part of his body extending above the ice must approximate “the height of the World Trade Center.” One must then ask how Dante, the narrator in the poem, is able to give such detailed descriptions of the tormented bodies of Cassius, Brutus, and Judas dangling from Satan’s mouth: “at their height they should be as insignificant a sight as a trio of deluded tourists waving from the top of the Empire State Building” (p. 44). One of the reasons why scholars have attempted to map the underworld so precisely is, as Kleiner points out, that Dante makes it seem so much more concrete than the “dreamlike” surface of earth. (Here C. S. Lewis may have taken a clue from Dante, in his notion that the concrete belongs to Heaven, that things on earth are only “shadowlands.”)The third chapter concerns Dante’s reputation as a student of classical literature. Here, focusing on two cantos of the Inferno and the Purgatorio, Kleiner considers Dante’s inaccurate citations from Virgil, Statius, and other [End Page 415] classical writers and his intentional use of “masterful distortions” to create the effect he wanted. In the fourth chapter, Kleiner discusses Dante’s use of scientific material, such as his precise description of the duration of a lunar eclipse that no one on earth would have been able to gauge and his design of an impossible experiment concerning reflected light. The final chapter associates Dante’s interest in Geryon, the monster who appears in Canto 16 of the Inferno, with the medieval fascination with the grotesque. Moreover, the Ovidian allusions in this canto, Kleiner believes, make the encounter with Geryon a meditation on poetry and show “fiction’s proximity to fraud, its perilous attractiveness, and its susceptibility to perversion” (p. 132). Thus the Geryon episode represents Dante’s concern with the dangers inherent in reading, dangers depicted earlier in the Inferno in, for example, the Francesca and Paolo episode of Canto V, in which the lovers had been seduced into committing adultery after reading the story of Lancelot and Guinevere. In such episodes, Dante reminds us of the power a writer has over his readers and of his duty not to use that power irresponsibly.Because of the post-Renaissance emphasis on the importance of unity in a work of art and the later emphasis on realism, earlier critics naturally emphasized the unity and consistency of Dante’s work. A great work, they assumed, had to have these qualities. As Kleiner’s book reminds us, however, earlier writers did not always prize them as highly as modern critics do, and some inconsistencies and errors (some deliberate, some not) seem to have been acceptable. Inaccurate citations of classical works are due in part to the fact that medieval writers often knew earlier works only from commonplace books and in part to... (shrink)

The Life of the Transcendental Ego presents essays by a number of distinguished writers in the continental tradition of philosophy. The essays include problems in transcendental philosophy, the nature of autobiography, the validity of existentialism, the possibilities of phenomenology, as well as focused discussions of concrete issues in aesthetics and ethics.

At the forefront of international concerns about global legislation and regulation, a host of noted environmentalists and business ethicists examine ethical issues in consumption from the points of view of environmental sustainability, economic development, and free enterprise.

Based on responses from 1078 human resource (HR) professionals, this study concludes that there is not an ethical crisis in the work place. Seven of 37 situations were rated as serious problems by more than 25% of the respondents. HR reported that their organizations are serious about uncovering and disciplining ethical misconduct, top management has a commitment to ethical business conduct, personal principles are not compromised to conform to company expectations, and performance pressures do not lead to unethical conduct.
