The encounter between Socrates and Thrasymachus in Republic I is notoriously baffling. Most of what is said seems straightforward, and the issues at stake are ones of common concern, but the argument remains elusive. The purpose of this paper is to investigate the nature and grounds of this elusiveness, and to show that some of it can be dispelled by a sufficiently free-ranging exegesis that bears in mind the general character of Plato’s writing.

The internal paradoxes in the quantum measurement scheme related to violation of conservation laws, changes in entropy, absence of a dynamic description of collapse, Wigner's friend, as well as the paradox of violation of causality in the EPR experiment are shown to be partially circumvented in the measurement scheme of stochastic quantum mechanics.

The language of manuals may be used to discuss inference in measurement in a general experimental context. Specializing to the context of the frame manual for Hilbert space, this inference leads to state dominance of the inferred state from partial measurements; this in turn, by Sakai's theorem, determines observables which are described by positive operator-valued measures. Symmetries are then introduced, showing that systems of covariance, rather than systems of imprimitivity, are natural objects to study in quantum mechanics. Experiments measuring different (...) polarization components simultaneously are reexamined in this language. Finally, implications of the Naimark extension theorem for the manual approach are investigated. (shrink)

Of the platonic theory that four qualities make up the whole of virtue. I show that aristotle's repudiation of this scheme is more apparent than real.

Nelson Goodman equates expression with metaphorical exemplification. That is, a character C in a symbol system expresses a property P if three conditions are fulfilled: C has P ; C exemplifies P ; and C has P metaphorically. Two points are emphasized. The first point is that a character actually is what it metaphorically is: sad music really is sad, really does express sadness, just as loud music really is loud. The decision to apply to works of art language that (...) is literally applicable only to persons is arbitrary, in that no reason can be given for it other than its felt aptness; but, once the decision to use the terminology has been made, decisions about which terms are applicable to which works are no more arbitrary than any other decisions about the applications of terms. The second point is that there is no intimate connection between the concept of expression as thus defined and the concepts of emotion or feeling. The latter merely furnish one common set of metaphors. (shrink)

The Presbyterian and Reformed tradition, as one representation of Biblical theology and ethics, has considerable application to physical health. This perspective is effectively embodied in the Westminster Confession of Faith which includes “the moral law,” especially as illustrated in the Larger Catechism Questions and Answers on the Ten Commandments. The WCF has many Biblical principles that promote health and prevent disease, for example, the Seventh Commandment can be “extensively demonstrated empirically” that violations promote morbidity and mortality. This result markedly contrasts (...) with the evolutionary and politically correct foundation of modern medicine that essentially promotes disease and death. Sexual “freedom” has become “slavery” to its disastrous results. Further, the modern attempt to define and treat “mental illness” does not begin to address the needs of patients and their families. By excluding the spiritual dimension of men and women, psychology and psychiatry has no moral answers by the naturalistic fallacy, and thus their various cognitive and pharmaceutical approaches mostly make “mental” problems worse. In this essay I present what the Bible claims through the WCF, and using modern medicine’s own “evidence-based medicine,” demonstrate how this approach has a strategic advantage in promoting health over contemporary medical ethics and practices.
