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.

« 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.

Title “I feel it in my fingers, I feel it in my toes: Imaginative Meditation and Experience of Love in Medieval Contemplative Philosophy”
4:10-6:00 PM
716 Philosophy Hall

Please join us for a talk by Eric-John Russell (Universität Potsdam), who will present chapters from his recently published book, Why Everything is as it Seems: Hegel and Debord. Jacob McNulty (University College London) will provide a response followed by a Q&A with our audience.

Guy Debord has been called many things: pseudo-philosopher, nihilist, filmmaker, megalomaniac, strategist, third-rate Mephistopheles. His book The Society of the Spectacle (1967) has fallen into a similarly motley reception, frequently enveloped within the discourses of postmodernism, media and cultural studies, and avant-garde art history. My research however, dispenses with such narratives and instead offers a sustained examination of the concept of the society of the spectacle through the two pillars upon which Debord understood his own work as a critical theory of society: Marx’s critique of political economy and Hegel’s speculative philosophy. It is the latter that will be the focus of my paper, first by offering some introductory remarks on Debord’s theory of the spectacle but then arguing  that it precisely the speculative dimension of Hegel’s dialectic that remains central for Debord’s diagnosis of twentieth century capitalism, with emphasis placed on the importance of Hegel’s Wesenslogik. I will conclude with the historical significance of Debord’s “heretical Hegelianism,” specifically as an intervention within the atmosphere of the French Hegelianism of the interwar and postwar period.

In Sanskrit epistemology, philosophers are preoccupied with the notion of pramā. A pramā, roughly, is a mental event of learning or knowledge-acquisition. Call any such mental event a knowledge-event. In A Confection of Refutation (Khaṇḍanakhaṇḍakhādya), the 12th century philosopher and poet Śrīharṣa argued that knowledge-events are indefinable. Any satisfactory (and therefore non-circular) definition of knowledge-events will have to include an anti-luck condition that doesn’t appeal back to the notion of learning or knowledge-acquisition itself. But there is no such anti-luck condition. What is novel about Śrīharṣa’s argument is that it is motivated by his commitment to a certain “knowledge first” approach to epistemology: the view that knowledge-events are epistemically prior to other non-factive mental states and events. On this view, when we are trying to determine whether an agent has undergone a knowledge-event, we don’t initially ascribe to them some other non-factive mental event, and then check if that event meets some further conditions (like truth or reliability) necessary for it to count as a knowledge-event; rather, we treat certain mental events by default as knowledge-events until a defeater comes along.  Surprisingly, Śrīharṣa argues that this kind of “knowledge first” epistemology should give us reason to doubt whether our ordinary attributions of knowledge-events are reliably tracking any sui generis psychological kind. In this talk, I reconstruct Śrīharṣa’s position.
