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.

Physicists and philosophers question the validity of one of the most observed and seemingly obvious appearance in our world: that time flows. Many in the physics and philosophy communities contend that the flow of time is not a fundamental feature of the world, nor even a fact of the world, but is an illusion. As a case in point, we will consider Brian Greene’s view of time in his PBS exposition “The Elegant Universe” holding that time may not flow, the past may not be gone, the future may already exist, and that now is not special. Most people, as observers of time’s passage, might agree with the Greek philosopher Heraclitus who expressed the idea that all is change and that change occurs with the flow of time. I will explore some of the motivation and reasons given for these positions and contrast the arguments made for each viewpoint.

F. Moltmann: Underspecification of Attitudes and Truthmaker Semantics
It has been argued that the satisfaction conditions of a desire can be underspecified by the complement clause. This provides support for the view according to which the complement clause gives a partial content of the reported desire, where partial content is formulated in terms of truthmaker theory. In this talk, I will discuss the extent of such underspecification and whether it truly supports a truthmaker-based approach to the content of attitudes.
Optional preparatory reading here.
F. Faroldi: Truthmaker Semantics for Justification Logics – Open Problems
Justification logics are a family of logic where "implicit" modal operators are substituted by explicit terms to get formulas of the form t : A, where t could be evidence, a reason, etc. why A is known, believed, obligatory, etc., thus resulting in an “objectual” approach to modalities. In this talk we explore how to give a truthmaker semantics for justification logics, we provide some philosophical reasons to do so, and note some technical open problems.
Cian Dorr: Truthmaking in the Object Language
I consider a simple language with Boolean connectives, sentential variables and quantifiers binding them, and a connective for propositional identity (‘for it to be the case that … is for it to be the case that …’). Using familiar techniques, the possible-worlds model theory for such a language can be ‘internalised’ to derive a theory stated in the language itself, based on the definition of ‘world-proposition’ as ‘maximal consistent proposition’, and this theory can be shown to follow from the theory that propositions form a complete atomic Boolean algebra. In this paper, I will consider to what extent something similar can be done for Fine’s truthmaker semantics. This will involve looking for a way of picking out a class of special propositions to serve as surrogates for the states, and a binary relation among propositions to serve as a surrogate for the verification relation, and using these definitions to rewrite the metalinguistic definition of a model as theory in the object-language. I will make a start at considering to what extent the axioms of this theory can be derived from an independently natural weakening of the theory that propositions form a complete atomic Boolean algebra.
The philosophical traditions of India offer contemporary researchers an unparalleled and mostly untapped resource for fresh thinking about attention, its relations to mind and world. From Nyāya manas-theory to the extensive Buddhist theories about attention’s relationship with consciousness, and from precise taxonomies of the varieties of attention to discussions about the norms governing attention, epistemic, moral, and practical, the wealth and sophistication of Indian analysis is astounding. Our workshop will look at the ways in which Indian, including Buddhist, philosophical theory can enrich contemporary discussion, and there will be presentations by a world-class panel of speakers.
We hope too that this workshop will serve as a catalyst to Indian philosophical studies in the New York area. The workshop is open to everyone, free and without registration, and the program is here.

“Harnessing the Wandering Mind”
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.

The New York University Department of Philosophy will host the sixteenth in its series of conferences on issues in the history of modern philosophy on November 8 and 9, 2019. Each conference in the series examines the development of a central philosophical problem from early modern philosophy to the present, exploring the evolution of formulations of the problem and of approaches to resolving it. By examining the work of philosophers of the past both in historical context and in relation to contemporary philosophical thinking, the conferences allow philosophy’s past and present to illuminate one another.

“Giving as Spending and Spending as Giving: Buddhism and the Politics of Spending during the Chosŏn Dynasty”
Juhn Ahn, University of Michigan
The impact of the Koryŏ-Chosŏn transition on the Buddhist establishment in Korea is generally understood in current scholarship to have been a negative one. It is all too often assumed that Buddhist monasteries, who enjoyed great economic prosperity under Koryŏ’s culture of giving, were forced to undergo a radical reduction in size and number and their wealth confiscated to replenish the empty royal fisc. There is also a tendency to assume that this systematic restructuring of the Buddhist establishment, often dubbed its “decline,” was orchestrated and executed by a small group of reform-minded Neo-Confucian scholar-officials who saw Buddhism as an economic parasite and cause of unnecessary spending. It is true that the Buddhist establishment never again enjoyed the kind of wealth that it once did during the Koryŏ, but this paper argues that we should not take this as a sign of decline or the necessary outcome of state suppression. Instead, this paper will turn its attention to the politics of spending that continued to shape and reshape the Chosŏn court and show that the politics of spending provided the Buddhist establishment with an opportunity—an opportunity that it did in fact use—to redefine the conditions of its existence.
“Court Lady Ch’ŏn Ilch’ŏng (1848 – 1934) in the Making of Modern Korean Buddhism”
Hwansoo Kim, Yale University
In this talk, I will introduce the work of a forgotten Korean Buddhist laywoman who served as one of the highest-ranking ladies in the court of the late Chosŏn dynasty. I will demonstrate that Court Lady Ch’ŏn (1848 – 1934) was as integral to modernizing Korean Buddhism during the pre-colonial and colonial era as the Korean Buddhist monastics with whom she worked. By examining Ch’ŏn’s seminal role in the incipient stage of modern Korean Buddhism, the history of female Buddhist leadership can be extended.
Ch’ŏn primarily worked with the Korean monk and leader Yi Hoegwang (1862-1933), drawing on a wide network of relationships both inside and outside the court to help him establish the first modern institution of Korean Buddhism, build the first modern temple in central Seoul, and open a Buddhist clinic. However, because Yi was later condemned by historiography as the worst of Buddhists who had collaborated with Korea’s colonizer, Ch’ŏn’s leadership and legacy were likewise stigmatized and sidelined. This talk seeks to restore Ch’ŏn’s centrality as a Buddhist modernizer, thereby giving balance to a largely male-centered and ethno-centric history and lengthening the lineage of lay female leadership in the transformation of Korean Buddhism in the early twentieth century.
“Buddhism and State Violence in Modern Korea”
Jin Y. Park, American University
Historically, Korean Buddhism has been known as “State Protection Buddhism” (護國佛敎). The seemingly positive character of this description also points to the limitations of Korean Buddhism’s role in the broader context of society. A state should exist to protect its members, but history has witnessed that the state can and did exercise its power against its members. Which members did the Korean government support, and which were sacrificed in the process? What role did Korean Buddhism play in the unfolding of that history?
This presentation deals with Buddhism’s response to state violence in modern Korea. Through an analysis of a specific instance of state violence and Korean Buddhism’s response, the presentation tries to gauge Korean Buddhism’s capacity to engage with the socio-political milieu of human existence.

The notion of an occurrence of a proposition in discourse is the subject of the following observation:
(O) A proposition may occur in discourse, now asserted, now unasserted, and yetbe recognizably the same proposition.
I shall argue that the true significance of this observation is utterly distorted by Geach’s manner of construing of it — a construal widely known today as “the Frege-Geach point”. Though it serves as a basis for a contemporary understanding of logical form, strictly thought through, this way of construing (O) can be shown to lead to absurdity. I will further argue that a straightforward, undistorted, acceptance of (O) is the key to a genuine philosophical logic.

« A Case against Simple-mindedness: Śrīgupta on Mental Mereology »
With responses from Alexander Englert (Princeton University)
ABSTRACT: There’s a common line of reasoning which supposes that the phenomenal unity of conscious experience is grounded in a mind-like simple subject. To the contrary, Mādhyamika Buddhist philosophers beginning with Śrīgupta (seventh-eighth century) argue that any kind of mental simple is incoherent and thus metaphysically impossible. Lacking any unifying principle, the phenomenal unity of conscious experience is instead an ungrounded illusion. In this talk, I will present an analysis of Śrīgupta’s “neither-one-nor-many argument” against mental simples and show how his line of reasoning is driven by a set of implicit questions concerning the nature of and relation between consciousness and its intentional object. These questions not only set the agenda for centuries of intra-Buddhist debate on the topic, but they are also questions to which any defender of unified consciousness or a simple subject of experience arguably owes responses.
We are excited to announce a public talk featuring Elie During as part of French philosopher Gaston Bachelard’s 60th death anniversary. On the face of it, The Dialectic of Duration, Gaston Bachelard’s 1936 essay, is a pungent—if often unfair—criticism of the Bergsonian doctrine of time and creative evolution. The constructive side of this Anti-Bergson has received less attention: it implies a genuine poetics of time based on the intuition of the sporadic and oscillatory nature of becoming. Bachelard’s rhythmic theme is consistent with the idea of “surrationalism” introduced that same year as a formal counterpart to the surrealist experiments carried out on the fringes of conscious experience. Inspired by the explosive potential of scientific revolutions already celebrated in Le Nouvel Esprit Scientifique, the surrationalist project can be interpreted as that of a poetics of reason. André Breton believed it would “act simultaneously as a stimulant and restraining influence” (“Crisis of the Object”). Insights from the scientific investigation of time as well as poetic and musical experience will help us see how this double action is in keeping with the eruptive dynamics of imagination and reason, as much as with Bachelard’s ideal of “self-surveillance”.
Elie During is an Associate Professor of Philosophy at the University of Paris Ouest. His research focuses on the philosophical implications of relativity theory. His publications include an introduction to Poincaré’s philosophy of science (La Science et l’Hypothèse, 2001), an essay on the nature of time (The Future does not Exist, 2014), two critical editions of Bergson, a coedited volume on contemporary metaphysics of realism (Choses en soi, 2018, English translation forthcoming from Edinburgh University Press), and most recently a critical edition of Bachelard’s Dialectique de la durée (2021).
