As practicing clinicians, physicians are expected to uphold the ethical norms of their profession, including fidelity to patients and respect for patients’ self-determination. At the same time, as individuals, physicians are moral agents in their own right and, like their patients, are informed by and committed to diverse cultural, religious, and philosophical traditions and beliefs. In some circumstances, the expectation that physicians will put patients’ needs and preferences first may be in tension with the need to sustain the sense of (...) moral integrity and continuity that grounds a physician’s personal and professional life. This article examines the implications for patients, physicians, and the medical profession when tensions arise between a physician’s professional commitments and his or her deeply held personal moral beliefs. It offers guidance on when a physician’s professional commitments should outweigh personal beliefs as well as when physicians should have freedom to act according to the dictates of conscience while still protecting patients’ interests.

Although the theory of definability had many important antecedents—such as the descriptive set theory initiated by the French semi-intuitionists in the early 1900s—the main ideas were first laid out in precise mathematical terms by Alfred Tarski beginning in 1929. We review here the basic notions of languages, explicit definability, and grammatical complexity, and emphasize common themes in the theories of definability for four important languages underlying, respectively, descriptive set theory, recursive function theory, classical pure logic, and finite-universe logic. We review (...) the history of previous studies of the similarities and differences in the theories of definability of the first three of these four languages. A seminal role leading toward unification of the theories has been played by the separation principles introduced by Nikolai Luzin in 1927. Emphasizing analogies and driving toward further unification embracing finite-universe logic we concentrate on a simple example—the first and second separation principles for existential-universal first-order sentences . Using this as a test case for the fundamental problem of how to “finitize” arguments in classical pure logic to the finite-universe case, we are led to the analogous negative solution by using the theory of certain special graphs: a graph is - special for any positive integers m , n , p , q iff it is bipartite with m red points and n blue points and for every p -tuple of red points there is a blue point to which they are all connected . As an aside we introduce for further study a natural “Ramseyesque” increasing sequence A of positive integers, where A is the least positive integer n for which an -special graph exists. (shrink)

The articles collected in this volume are concerned with the transmission and development of the Greek achievement among Syriac scholars of the Fertile Crescent during the four centuries after 500CE, particularly in the fields of rhetoric and philosophy. Cumulatively they show how many aspects of Greek culture were received and elaborated in Syriac, and contribute to understanding the ways in which that culture exercised a powerful influence on the medieval Near East and the burgeoning Islamic civilisation.
