Kidder's checklistfor ethical decrsion making is recommended as an addition to the existing canon of modelsfor mass media ethics. Contributions in Kidder's approach include his dichotomy between ethical dilemmas m d moral temptations, his tests for right-versus-wrong and right-versus-right issues, his framework by which to clarify values in ethical dilemmas, nnd his sequencing of the decision-making process. Kidder's model is surnmnrized nnd discussed, revisions are suggested for classroom use in medin ethics courses, nnd tke revised model is applied to media (...) ethics cases. (shrink)

Did Leibniz exploit infinitesimals and infinities à la rigueur or only as shorthand for quantified propositions that refer to ordinary Archimedean magnitudes? Hidé Ishiguro defends the latter position, which she reformulates in terms of Russellian logical fictions. Ishiguro does not explain how to reconcile this interpretation with Leibniz’s repeated assertions that infinitesimals violate the Archimedean property (i.e., Euclid’s Elements, V.4). We present textual evidence from Leibniz, as well as historical evidence from the early decades of the calculus, to undermine Ishiguro’s (...) interpretation. Leibniz frequently writes that his infinitesimals are useful fictions, and we agree, but we show that it is best not to understand them as logical fictions; instead, they are better understood as pure fictions.
