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.

Scholars working under the broad umbrella of New Materialism have offered compelling reappraisals of the ways in which we know, interact with, and exist in the world. This scholarship also intersects with recent work on music and sound, which raises rich sets of questions regarding human agency, material, ethics, aesthetics, embodiment, and the subject/object dichotomy, among other issues.
We invite scholars working in the humanities, arts and sciences to submit proposals for papers and performances that engage with the themes of sound and new materialism, broadly construed. We welcome work that adopts historical, technological, analytical, philosophical, materialist, and creative vantage points, among others. Overall, this conference will direct these diverse disciplinary and methodological perspectives towards convergent and critical issues, creating new, interdisciplinary lines of enquiry and generating original research.
The one-day conference will consist of panels that comprise of papers with short reflections by a moderator, as well as an evening concert that includes opportunities for discussion. The concluding concert of work that engages with these themes from creative perspectives will afford attendees with an opportunity to consider and discuss issues concerning sound, material, and agency in a forum that contrasts with, but also complements, our events during the day. Conference participants are strongly encouraged to attend both the daytime and evening portions of the conference.
Proposals are called for:
Paper presentations of 20 minutes with 10 minutes of Q&A.
Artistic presentation of 20 minutes with 10 minutes of discussion
Submission: Proposals of no more than 500 words (300 words for artistic presentation) should be submitted as a PDF by August 14th 2019 to jc5036@columbia.edu
and include “NMAS Submission” in the subject line. If you’re applying for an artistic presentation please include three representative 2 minute audio/video examples. Please also include the title of your proposed paper and anonymize your submission. Include your name, affiliation, and contact information in the body of the email, and also nominate any audio/visual requirements for your paper or performance.
This will be the third (and, time permitting, some material from the fourth) of a series of lectures that I aim to write up formally as a book. We will begin with a brief review of the most familiar theory of Chinese aesthetics: works of art are the products of sensitive human beings who cannot suppress their sincere responses to emotional stimuli. If art is understood as a sincere statement of this kind by a great genius, it stands to reason that, by correctly interpreting the work, one can communicate with that genius’s mind (xin 心) even after his or her death–and, likewise, that an artist today can communicate with audiences yet unborn. Art is thus timeless and offers the possibility of incorporeal immortality. If there is extra time, I will also survey two interrelated phenomena that I call meta-criticism and meta-writing (since there are no technical terms for them in Chinese). Meta-criticism, i.e. criticism of criticism, is a major feature of Chinese theories about art. Meta-criticism must be related to meta-writing, or the practice of writing about writing while exemplifying the very styles and techniques that one recommends: for example, artfully rhyming a couplet about rhyming.

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.

Poets and singers in a number of medieval vernacular languages reached non-native audiences and inspired speakers of other languages to compose in theirs; and many imagined their compositions enjoying a universality similar to that of cosmopolitan languages like Latin and Arabic. An interesting rationalization of these aspirations can be discerned in a short verse narrative of a well-known episode in the youth of Alexander the Great, conqueror of India, together with his tutor, the philosopher Aristotle. Not only does it involve Greeks and Indians singing French songs and cosplaying French lovers, but the philosopher is induced to pretend to be a horse and then justifies his behavior as “natural,” with far-reaching implications which this talk will explore.

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.

Well-being, also known as prudential value, refers to whatever makes a life non-instrumentally good for the person living it. Well-being is the object of immense practical, philosophical, and scientific concern. Assessments of well-being help to guide our decisions in everyday life, from relationships, to health decisions, to education and career choices. Well-being is increasingly the object of governmental and institutional policy, and even policies that are not aimed directly at promoting it can be evaluated in terms of their impacts on well-being. Colleges and universities routinely offer programs designed to help students maintain their well-being in the face of academic and personal stress. However, debates over the nature of well-being have raged since the beginning of philosophical inquiry, leaving us in a bad position when it comes to making headway on addressing those practical and scientific concerns. The goal of this talk is to show how the application of naturalistic methodology can help us to resolve the philosophical stalemate and thus to make progress in our practical and scientific projects relating to well-being.

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.
