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.

Socrates’ close association of madness and philosophy from the Phaedrus’ Palinode has puzzled interpreters. How can philosophy be equated to irrationality? In this paper I argue against interpretations that either deny that the association of madness and philosophy ought to be taken seriously or downplay this association by considering madness as akin to the unreflective inspiration characterizing only the first stages of philosophizing but subsequently overcome by the mature philosopher. I show that the association of madness and philosophy is an integral part of Socrates’ polemics against what he calls “human moderation”, characterized by a cold calculation of costs and benefits. And, moreover, that madness is an ongoing feature of philosophy and of the philosopher, who is never fully in possession of all his rational and cognitive processes but has to constantly work on them in an effort of self-clarification.

Book discussion on Gwenda-lin Grewal’s, Thinking About Death in Plato’s Euthydemus. A Close Reading and New Translation (OUP 2022)

Thinking of Death places Plato’s Euthydemus among the dialogues that surround the trial and death of Socrates. A premonition of philosophy’s fate arrives in the form of Socrates’ encounter with the two-headed sophist pair, Euthydemus and Dionysodorus, who appear as if they are the ghost of the Socrates of Aristophanes’ Thinkery. The pair vacillate between choral ode and rhapsody, as Plato vacillates between referring to them in the dual and plural number in Greek. Gwenda-lin Grewal’s close reading explores how the structure of the dialogue and the pair’s back-and-forth arguments bear a striking resemblance to thinking itself: in its immersive remove from reality, thinking simulates death even as it cannot conceive of its possibility. Euthydemus and Dionysodorus take this to an extreme, and so emerge as the philosophical dream and sophistic nightmare of being disembodied from substance. The Euthydemus is haunted by philosophy’s tenuous relationship to political life. This is played out in the narration through Crito’s implied criticism of Socrates-the phantom image of the Athenian laws-and in the drama itself, which appears to take place in Hades. Thinking of death thus brings with it a lurid parody of the death of thinking: the farce of perfect philosophy that bears the gravity of the city’s sophistry. Grewal also provides a new translation of the Euthydemus that pays careful attention to grammatical ambiguities, nuances, and wit in ways that substantially expand the reader’s access to the dialogue’s mysteries.
We are embarking on an innovative adaptation of J.P. Sartre’s timeless masterpiece, “No Exit.” Infused with elements inspired by Plato’s Dialogues, our play aims to explore the depths of existentialism, dark absurdity, and musical comedy while delving into the realms of speech and movement improvisation.
Through this innovative production, we aim to challenge and provoke audiences, encouraging deep introspection and dialogue about our existence and the choices we make. We believe that the combination of Sartre’s piercing insights and Plato’s philosophical foundations will create a unique theatrical experience that will resonate with both enthusiasts of classic literature and fans of contemporary performance art.
