Propositional dynamic logic (PDL) is a framework for reasoning about nondeterministic program executions (or, more generally, nondeterministic actions). In this setting, nondeterminism is taken as a primitive: a program is nondeterministic iff it has multiple possible outcomes. But what is the sense of “possibility” at play here? This talk explores an epistemic interpretation: working in an enriched logical setting, we represent nondeterminism as a relationship between a program and an agent deriving from the agent’s (in)ability to adequately measure the dynamics of the program execution. More precisely, using topology to capture the observational powers of an agent, we define the nondeterministic outcomes of a given program execution to be those …

Since Confucianism is an intergenerational phenomenon, it should have unique insights into ethical issues surrounding our obligations to future generations. In the first part of this discussion, I examine two contemporary Confucian perspectives on intergenerational ethics. Proponents of Confucian Role Ethics have developed an interpretation of xiao 孝 as “intergenerational reverence” that binds the community together over time by reference to shared cultural models and evolving ethical values. The Chinese thinker Jiang Qing in turn argues for a political constitution in which the state depends not just on the will of presently existing citizens, but also serves to preserve and transmit the values of the past for the sake of …
