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.

Neuroprediction, the use of neuroscientific data to predict human behavior, can sound like science fiction. But with the advent of neuroimaging and the continuing rapid development of other non-invasive brain measurements, neuroprediction is increasingly a real-world phenomenon.
Deep philosophical, legal, and neuroscientific questions arise regarding the use of these methods to predict behavior. Like all scientific tools, whether or not these technologies are used responsibly depends on who uses them. For instance, recent research illustrates the potential use of neuroprediction to assess an individual’s risk of (re-)engaging in antisocial conduct in forensic contexts. While the use of brain-based data may add predictive value to existing risk assessment tools, at the same time, the use (or misuse) of neuroprediction in courtrooms may imply violations of individual rights and liberties under the pretext of enhancing public safety. In addition to these legal implications, neuroprediction presents several technological and neuroscientific challenges. The non-invasive measures currently available are only indirect measures of cognitive activity. Understanding the conceptual, ethical, and legal dimensions surrounding the use of neuroprediction technologies helps crystallize the issues at hand and potentially provides moral guidance for those who wish to capitalize on these new tools as their prevalence and specificity continue to advance.
In this seminar, four experts from neuroscience, law, and philosophy will discuss recent findings in neuroprediction research, the predictive power of brain-based evidence compared to behavioral evidence, as well as the ethical and legal concerns emerging from the entrance of neuroprediction in the courts of law.

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.

How do we experience space? And what does this mean for the spaces we design? We explore these questions by bringing together speakers from Architecture, Neuroscience, and Virtual Reality, with two specific aims: First, we explore what Architecture and Virtual Reality can learn from each other, as two distinct approaches to “spatial design”. Whilst spatial experience has long been a central question of Architecture, Virtual Reality is only beginning to grapple with these questions, as technology transitions from 2D screens to 3D spatial interfaces. Second, we explore the nature of spatial experience itself, with two approaches to understanding the human mind. Whilst contemporary Architecture is influenced by Philosophy (specifically the “Phenomenological” tradition), the tools of Neuroscience are increasingly being applied to questions of Architecture as well. Through this multidisciplinary exchange we hope to deepen our understanding of spatial experience, and how it informs the physical and virtual spaces we design.

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?
Convenors
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.
