The concept of entropy in nonequilibrium macroscopic systems is investigated in the light of an extended equation of motion for the density matrix obtained in a previous study. It is found that a time-dependent information entropy can be defined unambiguously, but it is the time derivative or entropy production that governs ongoing processes in these systems. The differences in physical interpretation and thermodynamic role of entropy in equilibrium and nonequilibrium systems is emphasized and the observable aspects of entropy production are (...) noted. A basis for nonequilibrium thermodynamics is also outlined. (shrink)

I emphasize four points: Socratic dialectic challenges the interlocutor not only to acquire the correct moral opinions, but to question and think for oneself and to develop one's own moral rationality; it involves anticipatory acts of several types of virtue: courage, moderation, and justice and concern for the common good as opposed to competition and jealousy; what is at stake is not only the topic of the particular exchange, but the opportunity for membership in a rational/educational community; and the fact (...) that Socrates' interlocutors typically reject the opportunity for moral insight and personal growth he makes available to them explains why he cannot be said to possess a techne of moral education, and why he insists that virtue cannot be taught. The process of education through the elenchus is not a matter of correct instruction, but of rational elicitation, which must be responded to by personal choice. Thus Socrates' principles may represent not only beliefs he has tested over many years of dialogue, but also values he has come to through participation in elenctic inquiry, the idealized extension of norms required by and created in the practice of dialectic. Socratic education involves the interlocutor in the confrontation with a self whose irrational attachments of appetite and ego are exposed and must be overcome for the interlocutor to experience catharsis.

I contend that Jews, Christians, and Muslims who seek peace should not be reluctant to acknowledge the existence of their sometimes profound disagreements, or to affirm the truth of their own beliefs and practices. Since this places me at odds with John Hick, I analyze his views, granting the strengths of his critical realism and arguing that his revisionist-pluralist theory of religion has significant limitations for interreligious dialogue. Since the veridical-pluralist alternative I propose facilitates rather than stifles disagreement, I examine (...) three different conceptions of dialogue that acknowledge the importance of disputes among those searching for truth. I also discuss three virtues--honesty, empathy, and humility--whose cultivation would make us less likely to fail in our search for truth and the peace that is its sign and fruit. (shrink)
