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.

Critique is an assertion of values pitted against a state of affairs. To say that things should not be the way they are–to respond to questions such as ‘Why do I think this political or economic arrangement is wrong (and why should I care?)?’ implies an ethical stance. Critique thus draws together fact and value, domains that a long tradition of moral thought has argued exist on distinct planes. For there are dimensions of political life that are incomprehensible without this conjunction between ethical motivations and social realities. But if they are to have political consequences, such questions cannot be confined to private introspection. Scale matters. This talk looks at the articulation between everyday interactions and social movements to show the interplay among the first, second, and third person stances that characterize ethical life. Drawing ethnographic examples from American feminism and Vietnamese Marxism, it considers some of the ways in which ethical intuitions emerge, consolidate, and change, and argues that objectifications and the reflexivity they facilitate help give ethical life a social history.
Ronald Dworkin’s work always spanned a wide array of topics, from the most abstract jurisprudence through the details of American constitutional law all the way over to political philosophy and theories of justice and equality. In the last decades of his life, however, Dworkin’s work flowered in ways that went beyond even this prodigious range. Though he continued his central work in the philosophy of law and constitutional theory, he also addressed issues in international law, human dignity, the philosophy of religion, the relation between ethics, morality and legal theory, and the unity of practical thought generally. This conference will explore some of these themes in Dworkin’s late work. Beginning with a panel on his understanding of religion, we will also convene discussions of his work on legal integrity, international law, and the relation between law and morality. There will be a total of nine presentations, with plenty of time for discussion. All are welcome.
Panel 1 (Friday 1:30 p.m.): Dworkin’s Religion without God.
Eric Gregory (Princeton),
Moshe Halbertal (NYU and Hebrew U.) Ronald Dworkin Religion Without God: Morality and the Transcendent
Larry Sager (Texas) Solving Religious Liberty
Panel 2 (Friday 4:30 p.m.): Dworkin on international law.
Samantha Besson (Fribourg)
The Political Legitimacy of International Law: Sovereign States and their International Institutional Order
John Tasioulas (King’s College, London)
Panel 3 (Saturday 10 a.m.): The idea of integrity in Law’s Empire.
Andrei Marmor (Cornell) Integrity in Law’s Empire
Jeremy Waldron (NYU) The Rise and Decline of Integrity
Panel 4 (Saturday 2:15 p.m.): Law and morality in Justice for Hedgehogs.
Mark Greenberg (UCLA)
What Makes a Moral Duty Legal? Dworkin’s Judicial Enforcement Theory Versus the Moral Impact Theory
Ben Zipursky (Fordham)
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.
Certain intellectual challenges can neither be resolved by the discovery of missing pieces of information nor by construction of better arguments. Yet what is called for in such cases is not mere persuasion, but a form of intellectual transformation. Wittgenstein sought to respond to the problems of philosophy along similar lines. And the need for the notion of intellectual transformation arises in other contexts, as well, including the context of moral progress, which Cora Diamond explores in her recent work. But various philosophical difficulties stand in the way of embracing the idea that transformation has any role to play when it comes to questions or truth and of value. In particular, it seems that we must either bracket the psychological, historical and anthropological perspectives that the notion of transformation opens up, or else succumb to some form of relativism. My aim in this paper is to show how Wittgenstein and Diamond chart a middle course between these two extremes
