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.

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.

Presents: Li Zehou on the ‘Deep Structures of Confucianism’
Lead Presenter: Andrew Lambert (College of Staten Island, CUNY)
Discussants: Robert A. Carleo III (East China Normal University), Emma Buchtel (Hong Kong Education University)
ABSTRACT: Contemporary Chinese intellectual Li Zehou’s cross-cultural methodology blends traditional Confucian thought with thinkers such as Kant and Marx. This seminar addresses the question of culture and its role in Li’s thought. Li has made several claims about how a settled cultural tradition influences the subjects within it. One such claim concerns the existence of ‘deep structures’ of Confucianism, as outlined in this preparatory reading. The idea is that culture, history, and social practice (collectively, a tradition) shape human psychology (including the formation of concepts, emotions, and values) in ways not always apparent to the subject. Within the Chinese tradition, Confucianism constitutes such a deep structure, and its effects cannot be captured by textual studies alone, nor studies of material culture. Rather, the deep structure is articulated in terms of an emergent shared subjectivity. Such traditions can evolve and ultimately dissolve; nevertheless, their effects are deep-rooted. This seminar meeting will aim to identify the parameters of Li’s ambitious theoretical framework and its plausibility, and to explore connections with current work in related fields, such as cultural and empirical psychology.

ABSTRACT: Recent philosophical discussions on compassion focus on the value and the nature of compassion as an emotion. Ancient Asian philosophical traditions such as Confucianism and Buddhism, however, emphasize compassion as a character trait that should be nurtured. This paper examines the insights drawn from these traditions to help inform the nurturing of compassion. For example, is empathy a necessary tool? What is the role of love and care? Does self-reflection contribute to the process?

In Sanskrit epistemology, philosophers are preoccupied with the notion of pramā. A pramā, roughly, is a mental event of learning or knowledge-acquisition. Call any such mental event a knowledge-event. In A Confection of Refutation (Khaṇḍanakhaṇḍakhādya), the 12th century philosopher and poet Śrīharṣa argued that knowledge-events are indefinable. Any satisfactory (and therefore non-circular) definition of knowledge-events will have to include an anti-luck condition that doesn’t appeal back to the notion of learning or knowledge-acquisition itself. But there is no such anti-luck condition. What is novel about Śrīharṣa’s argument is that it is motivated by his commitment to a certain “knowledge first” approach to epistemology: the view that knowledge-events are epistemically prior to other non-factive mental states and events. On this view, when we are trying to determine whether an agent has undergone a knowledge-event, we don’t initially ascribe to them some other non-factive mental event, and then check if that event meets some further conditions (like truth or reliability) necessary for it to count as a knowledge-event; rather, we treat certain mental events by default as knowledge-events until a defeater comes along. Surprisingly, Śrīharṣa argues that this kind of “knowledge first” epistemology should give us reason to doubt whether our ordinary attributions of knowledge-events are reliably tracking any sui generis psychological kind. In this talk, I reconstruct Śrīharṣa’s position.

What is an appropriate response to humiliating treatments such as insults? This question is not only relevant to today’s discourse but has also piqued the curiosity of thinkers in classical Chinese philosophy. The Warring States period debate regarding whether one’s inner sense of shame can shield one from insulting situations and from experiencing shame is frequently presented as a one-sided narrative that focuses on the Confucian texts. Meanwhile, the views of their rival thinkers, such as the Daoist, legalist, or much-neglected Songzi (3rd century BCE), are rarely the focus of attention. This paper brings Songzi, a key player in the debate of emotions as responses to external triggers, into the picture and restores the historical intellectual discourse over the topic of what constitutes an appropriate response to humiliating situations such as insults. More importantly, I point out the philosophical significance of this debate, namely how Songzi prompts Xunzi to respond to an ambiguity within the Confucian doctrine: The early Confucians appear to think that an individual’s internal virtues can isolate and shield one from hostile external stimuli while also maintaining that the external environment impacts one’s moral cultivation and moral life in significant ways. Xunzi’s strategic move, I argue, is to give credit to both an inner sense of shame and the function of external stimuli in inducing negative emotions, thus making an important philosophical concession compared to Confucius and Mencius.

Individuals support forms of domination with varying levels of understanding that they are doing so. In many cases, those very structures of domination distort our conceptions of them through mechanisms such as motivated reasoning, implicit bias, affected ignorance, false consciousness, and belief polarization. These various epistemic distortions, in turn, cause social conflict, notably by promoting political polarization. Those worried by social conflict have spent a great deal of energy decrying the increasingly polarized contexts in which we live. However, epistemic distortions in our sociopolitical beliefs also misrepresent, maintain systems of domination and prevent human needs from being met.
This workshop aims to go beyond pronouncements such as ‘we are polarized’ or that ‘partisanship is on the rise,’ and begin to think through epistemic distortions at the individual and intersubjective levels, the role of criticism and critique in facilitating belief and social change, and the idea of reconciliation, by asking questions such as:
- In what ways are individual beliefs about domination/social structures epistemically distorted?
- What explains why social beliefs are epistemically distorted?
- What are the normative upshots of epistemic distortion for social relationships like allyship, comradeship, and friendship?
- Ought polarization be remedied? Which epistemic resources and theoretical frameworks avail themselves of emancipatory potential?

Ege Yumuşak is a philosopher, specializing in epistemology, the philosophy of mind, and social & political philosophy. She received a PhD in Philosophy from Harvard University in 2022. Her research examines political disagreement—its material foundations, psychological and social manifestations, and epistemic properties. She is currently writing a series of articles on the nature and significance of clashes of perspective in social life.
Nicolas Côté is a postdoctoral researcher at the University of Toronto. His research is mainly in normative ethics and social choice theory, but they also dabble in applied ethics and issues of practical rationality. Côté’s doctoral dissertation work focuses on the measurement of freedom, especially on axiomatic approaches to the measurement question, and on how deontic concerns for protecting individual rights interact with welfarist concerns for improving the general welfare. Côté’s current research focuses on the ethics of decision-making under radical uncertainty.
