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.

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.

Making Space for Justice: Social Movements, Collective Imagination, and Political Hope
by Michele M Moody-Adams

From nineteenth-century abolitionism to Black Lives Matter today, progressive social movements have been at the forefront of social change. Yet it is seldom recognized that such movements have not only engaged in political action but also posed crucial philosophical questions about the meaning of justice and about how the demands of justice can be met.

Michele Moody-Adams argues that anyone who is concerned with the theory or the practice of justice—or both—must ask what can be learned from social movements. Drawing on a range of compelling examples, she explores what they have shown about the nature of justice as well as what it takes to create space for justice in the world. Moody-Adams considers progressive social movements as wellsprings of moral inquiry and as agents of social change, drawing out key philosophical and practical principles. Social justice demands humane regard for others, combining compassionate concern and robust respect. Successful movements have drawn on the transformative power of imagination, strengthening the motivation to pursue justice and to create the political institutions and social policies that can sustain it by inspiring political hope.

Making Space for Justice contends that the insights arising from social movements are critical to bridging the gap between discerning theory and effective practice—and should be transformative for political thought as well as for political activism.

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.

This event will feature a thought-provoking panel discussion with sexual and reproductive justice experts on the value of the sexual and reproductive justice framework and how it can be applied to diverse stakeholders, settings, and contexts. Panelists will also highlight examples from around the world of momentum towards sexual and reproductive justice.

The COVID-19 pandemic is said to be a once-in-a-century incident, and it brought to us a sense of crisis at various levels. What is a crisis, though? Can any unnerving moment or period be called a crisis, or are there different dimensions of a crisis to which we need to be attentive? Is solidarity possible after experiencing a crisis like Covid-19? Can Buddhism make any contribution to facilitating solidarity? This presentation explores the meaning and nature of a crisis and our responses to it by drawing on modern Korean political thinker Pak Ch’iu’s (1909–1949) analysis of crisis and feminist-Buddhist thinker Kim Iryŏp’s (1896–1971) Buddhist philosophy. By doing so, this presentation considers what social, political, existential, and even religious meaning we can draw from our experience of crises, and what questions these insights present to us.

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.
