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.

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.

The philosophical and psychological literature on well-being tend to focus on the prudential value of positive emotions such as pleasure, joy, or gratitude. But how do the negative emotions such as grief fit into our understanding of well-being? It is often assumed that negative emotions are intrinsically bad far us and that we should work toward eliminating them, especially from the perspective of our own well-being.
In this presentation I want to question this assumption by drawing on the ideas of Zhuangzi (a prominent early Daoist thinker from the 4th Century BCE) to argue that negative emotions are not intrinsically bad for us, and that their prudential value or disvalue is context dependent. Zhuangzi’s outlook, with his focus on the flexibility of perspectives and living according to our natural, spontaneous inclinations, gives us reason to reconsider the role of negative emotions in our lives and how we might think about them in a more constructive way.

Conceptual misalignment is a pervasive phenomenon in the studies of Non-Western philosophy and the History of Philosophy (NW&HP). However, conceptual misalignment is often undetected, unsuspected, or seen as a hurdle that NW&HP materials need to overcome to contribute to contemporary discussions. Specifically, conceptual misalignment refers to the following: In the process of crystalizing NW&HP materials, a linguistic coordination of concepts is formed between the speaker, i.e., NW&HP, and its context of contemporary anglophone philosophy. However, in philosophically meaningful ways, the original NW&HP concept and its anglophone counterpart misalign. This misalignment is particularly intricate and hard to detect when it comes to emotion concepts, as they are thought to involve phenomenal and/or intentional features. Through investigating the concept of emotion in Chinese philosophy, I propose a refocusing on conceptual misalignment as a method of cross-cultural comparative and history of philosophy. Moreover, I argue that conceptual misalignment is an important resource for contemporary conceptual engineering and amelioration projects.
