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.

Neuroprediction, the use of neuroscientific data to predict human behavior, can sound like science fiction. But with the advent of neuroimaging and the continuing rapid development of other non-invasive brain measurements, neuroprediction is increasingly a real-world phenomenon.
Deep philosophical, legal, and neuroscientific questions arise regarding the use of these methods to predict behavior. Like all scientific tools, whether or not these technologies are used responsibly depends on who uses them. For instance, recent research illustrates the potential use of neuroprediction to assess an individual’s risk of (re-)engaging in antisocial conduct in forensic contexts. While the use of brain-based data may add predictive value to existing risk assessment tools, at the same time, the use (or misuse) of neuroprediction in courtrooms may imply violations of individual rights and liberties under the pretext of enhancing public safety. In addition to these legal implications, neuroprediction presents several technological and neuroscientific challenges. The non-invasive measures currently available are only indirect measures of cognitive activity. Understanding the conceptual, ethical, and legal dimensions surrounding the use of neuroprediction technologies helps crystallize the issues at hand and potentially provides moral guidance for those who wish to capitalize on these new tools as their prevalence and specificity continue to advance.
In this seminar, four experts from neuroscience, law, and philosophy will discuss recent findings in neuroprediction research, the predictive power of brain-based evidence compared to behavioral evidence, as well as the ethical and legal concerns emerging from the entrance of neuroprediction in the courts of law.

Topics relate to mind, social philosophy, epistemology, aesthetics, experimental philosophy, and psychology. The workshop will be 1 day long. Participants should not feel obligated to attend every session, but we do ask you to RSVP (this is to make sure everyone is allowed Saturday building access). If you think there is a chance you will join us for any part of the day, please send your name to Sarah Arnaud, postdoc in the Philosophy Program and co-organizer: sarnaud@gc.cuny.edu

The current pandemic has focused attention on the techniques used by epidemiologists and other non-experimental scientists to infer causal hypotheses from correlational data. I have previously argued* that we need to explain these techniques by reducing causal relationships to dependencies in systems of structural equations with probabilistically independent exogenous variables. In this talk I shall aim to use this account to cast light on (a) single-case counterfactual dependence and actual causation, (b) the content and practical relevance of generic causal claims like “smoking causes cancer”, (c) the temporal asymmetry of causation, and (d) the proper understanding of rational action under risk.
*In particular, I’ve argued this in http://weebly-file/1/8/5/5/18551740/stat_nat_csn_monist.pdf. I will also be giving a talk on it at the CUNY Logic and Metaphysics workshop on Monday 7 March 1615-1815.
The talk will be on Zoom. All are welcome to attend!
The zoom link will be distributed through the MAPS mailing list. If you are not on the MAPS mailing list and would like to receive the Zoom link for the talk, please email nyphilsci@gmail.com.
Naked Statistical Evidence and Verdictive Justice
This conference celebrates the 50th anniversary of the first publication of Saul Kripke’s masterpiece, Naming and Necessity, by showcasing new work on a range of topics on which it has had a lasting influence. These topics include, but are not limited to: the nature of names and natural kind terms; the failure of the description or cluster/description theories; the distinction between metaphysical necessity and epistemic apriority; empty names; the metaphysics of essence and origin; the nature of modality and possible worlds; conceivability and the epistemology of modality; the role of philosophical intuition; and the mind-body problem.
Dates: 12th and 13th December, from 9am to 5pm.
Venue: The CUNY Graduate Center, 365 5th Avenue, New York, New York.
Format: hybrid
Registration: for both online and in person attendance, please register by the 28th of November, 2022 at https://forms.gle/Jbr3uaFx1ZwRxJpZ7.

The COVID-19 pandemic is said to be a once-in-a-century incident, and it brought to us a sense of crisis at various levels. What is a crisis, though? Can any unnerving moment or period be called a crisis, or are there different dimensions of a crisis to which we need to be attentive? Is solidarity possible after experiencing a crisis like Covid-19? Can Buddhism make any contribution to facilitating solidarity? This presentation explores the meaning and nature of a crisis and our responses to it by drawing on modern Korean political thinker Pak Ch’iu’s (1909–1949) analysis of crisis and feminist-Buddhist thinker Kim Iryŏp’s (1896–1971) Buddhist philosophy. By doing so, this presentation considers what social, political, existential, and even religious meaning we can draw from our experience of crises, and what questions these insights present to us.

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.
