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.

Convergence to the truth is viewed with some ambivalence in philosophy of science. On the one hand, methods of inquiry that lead to the truth in the limit are prized as marks of scientific rationality. But an agent who, by using some method, expects to always converge to the truth seems to fail a minimum standard of epistemic modesty. This point was recently brought home by Gordon Belot in his critique of Bayesian epistemology. In this paper I will study convergence to the truth theorems within the framework of Edward Nelson’s radically elementary probability theory. This theory provides an enriched conceptual framework for investigating convergence and gives rise to an appropriately modest from of Bayesianism.

This paper is on the topic of deliberative autonomy in (primarily) post-classical Chinese moral epistemology. By “deliberative autonomy,” I mean the epistemic state or achievement in which one’s ethical views or beliefs are those that seem right to oneself and are based on reasons or considerations that one understands for oneself. This is to be contrasted with holding a view or belief based primarily on the authority or expertise of others, without seeing for oneself that the view is correct or why it is correct. The Chinese philosophical tradition is rich in discussion of the nature, value, and function of deliberative autonomy, having much to say both in its defense and against it. I will focus my discussion by looking more closely at what Neo-Confucians have said about a particular term of art, zide 自得 (“getting it oneself”). I translate and discuss some passages on “getting it oneself” in the works and recorded lessons of influential Song, Ming, and Qing Confucians, note different types of deliberative autonomy implied by these passages, and discuss Wm. Theodore de Bary’s famous explication of “getting it oneself.” I consider whether the premium these Confucians placed on zide has the implications for liberal education that de Bary proposes and describe how proponents of zide could respond to formidable and important Xunzian arguments for deference to traditions and expertise.

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.
