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 outcomes that the agent is unable to rule out in advance. In this framework, determinism coincides exactly with continuity: that is, determinism is continuity in the observation topology. This allows us to embed PDL into (dynamic) topological (subset space) logic, laying the groundwork for a deeper investigation into the epistemology (and topology) of nondeterminism.

The seminar is concerned with applying formal methods to fundamental issues, with an emphasis on probabilistic reasoning, decision theory and games. In this context “logic” is broadly interpreted as covering applications that involve formal representations. The topics of interest have been researched within a very broad spectrum of different disciplines, including philosophy (logic and epistemology), statistics, economics, and computer science. The seminar is intended to bring together scholars from different fields of research so as to illuminate problems of common interest from different perspectives. Throughout each academic year, meetings are regularly presented by the members of the seminar and distinguished guest speakers.

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 future generations. While both interpretations share in common a critique of Western individualism and rights-based ethical framework, Jiang’s account of Confucian intergenerationality rests on the authority of tradition, whereas Confucian Role Ethics prioritizes the uniqueness of the situation at hand. In the second half of the discussion, I develop an alternative Confucian approach that is aligned with virtue ethics. On this view, our present virtue is the point of departure for understanding our relations with the past and future. I examine passages in early Confucian texts that suggest a notion of intergenerational virtue, which brings together various dispositions to see our own flourishing as linked with both past and future generations.

Convergence to the truth is viewed with some ambivalence in philosophy of science. On the one hand, methods of inquiry that lead to the truth in the limit are prized as marks of scientific rationality. But an agent who, by using some method, expects to always converge to the truth seems to fail a minimum standard of epistemic modesty. This point was recently brought home by Gordon Belot in his critique of Bayesian epistemology. In this paper I will study convergence to the truth theorems within the framework of Edward Nelson’s radically elementary probability theory. This theory provides an enriched conceptual framework for investigating convergence and gives rise to an appropriately modest from of Bayesianism.

This essay tries to develop a “black radical Kantianism” – that is, a Kantianism informed by the black experience in modernity. After looking briefly at socialist and feminist appropriations of Kant, I argue that an analogous black radical appropriation should draw on the distinctive social ontology and view of the state associated with the black radical tradition. In ethics, this would mean working with a (color-conscious rather than colorblind) social ontology of white persons and black sub-persons and then asking what respect for oneself and others would require under those circumstances. In political philosophy, it would mean framing the state as a Rassenstaat (a racial state) and then asking what measures of corrective justice would be necessary to bring about the ideal Rechtsstaat.

Recently, a group of scholars has challenged the moral legitimacy of Confucian democracy from a liberal philosophical standpoint. According to these scholars, including political liberals and moderate perfectionists, any attempt to create a Confucian democratic theory inevitably confronts a dilemma—let us call this the pluralism dilemma—with the following two horns: (a) a free society is characterized by the plurality of mutually incompatible, often conflicting, moral, philosophical, and religious doctrines that guide an individual’s conception of the good life and a truly democratic theory is required to accommodate as many reasonable conceptions of the good and comprehensive doctrines as possible and (b) a Confucian democratic theory gives a privileged normative standing to Confucianism over other competing comprehensive doctrines. This paper defends Confucian democracy against this pluralism challenge by articulating its political purpose and constitutional structure, which are commonly dismissed in the critics’ analytical frameworks.
