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.

Memorial
A memorial service will be held at 5PM at St. Paul’s Chapel on the Columbia campus. Reception to follow on the 7th floor of Philosophy Hall.
Columbia University’s Department of Philosophy, the Morningside Institute, and the Thomistic Institute invite graduate students in philosophy, theology/religious studies, literature, and related disciplines to submit papers for “The Moral Imagination of the Novel.” The conference will examine the ways in which individual novels and the novel as a literary genre can be understood both to depict the search for moral, philosophical, and religious truth and to engage in this very search themselves. Is the novel a realistic or idealistic genre? Can novels expand our sense of moral possibilities? Can they contract them?
The conference will begin with four twenty-minute graduate student papers on Friday, October 4, followed by talks that day and the next from faculty. Confirmed speakers include:
Paul Elie (Georgetown)
Ann Astell (Notre Dame)
Thomas Pavel (Chicago)
Lauren Kopajtic (Fordham)
Dhananjay Jagannathan (Columbia)
Limited financial assistance is available to defray the cost of travel for student presenters, but students are encouraged to seek funds from their own institutions as well.
One-page proposals should be emailed to Molly Gurdon at mcg2197@columbia.edu by Saturday, August 31 to be considered. Invitations to present papers will be sent by Friday, September 6. Submissions should not contain any identifying information except for a title, but the author’s institution and program, along with the title of their proposed submission, should be noted in the e-mail submission.
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.
David Albert’s work has been of seminal importance to the foundations of physics, exerting central influence on the direction the field and laying foundations for much of its ongoing development. In celebration of David’s many past and continuing contributions, we will be hosting a conference at Columbia University on the foundations of physics. We expect talks on a range of topics, including the foundations of quantum mechanics and statistical mechanics, the possible emergence of space and time, the metaphysics of science, and the nature of agency.
