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.

Artificial intelligence (AI) promises to automate and scale solutions to perennial accessibility challenges (e.g., generating image descriptions for blind users). However, research shows that AI-bias disproportionately impacts people already marginalized based on their race, gender, or disabilities, raising questions about potential impacts in addition to AI’s promise. In this talk, Cynthia Bennett will overview broad concerns at the intersection of AI, disability, and accessibility. She will then share details about one project in this research space that led to guidance on human and AI-generated image descriptions that account for subjective and potentially sensitive descriptors around race, gender, and disability of people in images.

The pandemic compels us to ask fundamental questions about our place in the world: the many ways humans rely on one another, how we vitally and sometimes fatally breathe the same air, share the surfaces of the earth, and exist in proximity to other porous creatures in order to live in a social world. What we require to live can also imperil our lives. How do we think from, and about, this common bind?

In What World Is This? A Pandemic Phenomenology, Judith Butler shows how COVID-19 and all its consequences—political, social, ecological, economic—have challenged us to reconsider the sense of the world that such disasters bring about. Drawing on the work of Max Scheler, Maurice Merleau-Ponty, and critical feminist phenomenology, Butler illuminates the conditions in which we seek to make sense of our disorientation, precarity, and social bonds. What World Is This? offers a new account of interdependency in which touching and breathing, capacities that amid a viral outbreak can threaten life itself, challenge the boundaries of the body and selfhood. Criticizing notions of unlimited personal liberty and the killing forces of racism, sexism, and classism, this book suggests that the pandemic illuminates the potential of shared vulnerabilities as well as the injustice of pervasive inequalities.

Exposing and opposing forms of injustice that deny the essential interrelationship of living creatures, Butler argues for a radical social equality and advocates modes of resistance that seek to establish new conditions of livability and a new sense of a shared world.

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.
