Bjorndahl: The Epistemology of Nondeterminism. Logic, Probability, and Games Seminar @ Faculty House, Columbia U
Mar 29 @ 4:00 pm

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.

How AI Is Changing Artistic Creation @ Online
Oct 26 @ 2:00 pm – 3:30 pm

Generative art made with algorithms has existed since the early days of computing in the 1960s. In recent years, a new strand of generative art has emerged: AI-generated art, which leverages the recent progress of artificial intelligence to create artworks. Unlike old-fashioned generative art, AI-generated art is not produced with an explicit set of programming instructions provided by human artists; instead, it involves training an algorithm on a dataset so that it can later produce artworks (images, music, or video clips) using its own internal parameters that have not been explicitly defined by a human. This process raises fascinating questions at the intersection of computer science, art history, and the philosophy of art. At a superficial level of analysis, AI-generated art seems to offload much of the creative impetus of art production to the machine, requiring minimal intervention from the artist. On closer inspection, however, it involves a novel process of curation at two key stages: upstream in the selection of the dataset on which the algorithm is trained, and downstream in the selection of the outputs that should qualify as artworks. Instead of replacing human artists with computers, AI-generated art can be understood as a new kind of collaboration between mind and machine, both of which contribute to the aesthetic value of the final artwork.

This seminar will bring together AI artists and philosophers to explore the significance of this new mode of art production. It will discuss the implications of AI-generated art for the definition of art, the nature of the relationship between artists and tools, the process of digital curation, and whether AI systems can be as creative as humans.

Śrīharṣa on the Indefinability of Knowledge. Nilanjan Das (U Toronto) @ Faculty House, Columbia
Mar 24 @ 5:30 pm – 7:30 pm

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.

Conception and Its Discontents @ Heyman Center, 2nd floor common room
May 8 – May 9 all-day

A conference hosted by the Motherhood and Technology Working Group at the Center for the Study of Social Difference on the theme of “Conception and Its Discontents.”

Medical technologies have radically transformed the biological and social experience of motherhood. Advances in genomic and reproductive care, the circulation of novel kinship structures, the entrenchment of existing global networks of power and privilege, and the politics of contested bodily sites mark this emerging constellation.

Technological advancements have in particular impacted not just the understanding of conception, but the very process by which a human embryo is created, implanted, and matured. Egg freezing, embryo storage, IVF, and surrogacy afford women new freedoms in choosing when and how to become mothers, while also raising troubling questions about the pressures of capitalism and the extension of worklife, as well as the global inequalities present in the experience of motherhood. In addition, technologies have arisen allowing for unprecedented control over not just who becomes a mother, but what kind of embryo is allowed to be implanted and to grow. Technologies such as CRISPR and NIPT have re-introduced the question of eugenics, radically shifting the very epistemology of motherhood and what it means to be “expecting.” And contemporary abortion debates draw on technology in order to make arguments both for and against access, with imaging technologies being instrumentalized in the building of a sympathetic case for the unborn, and the very notion of a “heartbeat bill” reliant on the misreading of technologies for measuring fetal activity.

While these problems are urgent today, questions of conception and technology are by no means recent developments. The 18th century saw a flourishing of philosophical and scientific theories regarding the start of human life and its formation within the womb. Such theories relied on modern technologies, such as autopsy, to atomize and visualize the body. In the 19th and 20th centuries, eugenic medical science produced theories of reproductive difference between differing racial and social groups, leading to forced sterilization laws in both the US and in Germany. This long history of racializing the rhetoric of fertility and motherhood continues to influence political debates on immigration and demographic changes in the present.

Beyond Polarization: Epistemic Distortion and Criticism @ Heyman Center, 2nd foor common room
Nov 8 all-day

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.

An Artificial History of Natural Intelligence: Thinking with Machines from Descartes to the Digital Age @ East Gallery, Maison Française
Mar 6 @ 6:00 pm – 7:30 pm

David Bates, in conversation with Stefanos Geroulano and Joanna Stalnaker

We imagine that we are both in control of and controlled by our bodies—autonomous and yet automatic. This entanglement, according to David W. Bates, emerged in the seventeenth century when humans first built and compared themselves with machines. Reading varied thinkers from Descartes to Kant to Turing, Bates reveals how time and time again technological developments offered new ways to imagine how the body’s automaticity worked alongside the mind’s autonomy. Tracing these evolving lines of thought, David Bates discusses his new book, An Artificial History of Natural Intelligence, which offers a new theorization of the human as a being that is dependent on technology and produces itself as an artificial automaton without a natural, outside origin.
David Bates is Professor of Rhetoric at the University of California Berkeley. His research focuses on the history of legal and political ideas, and the relationship between technology, science, and the history of human cognition.

Stefanos Geroulanos is the Director of the Remarque Institute and Professor of European Intellectual History at NYU. He usually writes about concepts that weave together modern understandings of time, the human, and the body. His new book is a history of the concepts, images, and sciences of human origins since 1770, forthcoming from Liveright Press as The Invention of Prehistory: Empire, Violence, and Our Obsession with Human Origins in 2024.

Joanna Stalnaker is Professor of French at Columbia. She works on Enlightenment philosophy and literature, with a recent interest in how women shaped the Enlightenment. Her new book, The Rest Is Silence: Enlightenment Philosophers Facing Death, will be published by Yale University Press in the Walpole series.
