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.

In this session, Mandik will expand on his idea that persons are abstract things. To do this, he will discuss recent philosophical issues about personal identity, mind-uploading, and whether you could upload your mind to a piece of technology and survive.

The workshop, which is now in its 10th year, aims to foster exchange and collaboration among scholars, students, and anyone with an interest in Early Modern Philosophy. This year’s workshop will focus on the topic of “Mind, Body, Passion” in Early Modern Philosophy (roughly the period from 1600-1800).
We welcome submissions on the conference topic, which may be broadly construed to include mind-body identity, mind-body interaction, embodiment, philosophy of emotion, aesthetics, etc. For consideration, please submit abstracts of 250-300 words to newyorkcityearlymodern@gmail.com no later than December 31, 2019.

The rich philosophical and mathematical disputes that took place between Isaac Newton and Gottfried Leibniz at the start of the eighteenth century have received more historical attention than any other exchange in the history of philosophy. Nevertheless, in this talk, Robert Iliffe discusses a prominent but neglected aspect of their disagreement, namely the mutual claim that their opponents’ conceptual foundations were fictional, and were the product both of diseased thinking and of illegitimately organized intellectual structures. Newton assailed Leibniz’s allegedly debased metaphysics in various prominent places, and mobilized allies such as Roger Cotes and John Keill to do the same. Nevertheless, by far the most sophisticated critique of illicit philosophical assumptions was launched against Newton by Leibniz in his correspondence with Samuel Clarke. In the Fifth letter to Clarke, Leibniz identified core Newtonian positions as infantile, vulgar, and profoundly irreligious, asserting that they were dangerous fictions that were less plausible and much less edifying than the rational romances of writers in the previous century. Although Leibniz saved his most potent intellectual weapons for his final letter to Clarke, Robert Iliffe suggests that his attack on the fictional status of Newton’s work was no mere codicil to his general critique of Newton’s philosophy, but instead lay at the heart of it. This famous debate, while of course somewhat sui generis, is indicative of more general and dynamic features of intellectual debate.
