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.

In recent years, academic philosophers have increasingly pursued what is now called “public philosophy.” Almost everyone agrees that this development is positive. But what is public philosophy? What should it be? And why does it matter? Looking back to models both ancient and modern, this talk will be an exercise in public philosophy that explores the nature and value of public philosophy.
A reception will follow the lecture.

Over the last decades, the humanities have come under pressure from the scientific worldview. To many, it seems as if the humanities provide us at best with less-than-objective knowledge claims. Arguably, there are at least two overall reasons for this. On the one hand, the scientific worldview tends to associate objectivity with the kind of knowledge-acquisition, explanation, and justification characteristic of the natural sciences. On the other hand, the humanities themselves have contributed to the impression that they might be less relevant than the natural sciences to epistemic progress due to internal problems having to do with the very concept(s) of knowledge, reality and objectivity.
New Realism is a term for a whole series of current trends in philosophy that has important consequences for our understanding of knowledge in general. In particular, it reshapes our account of the human being qua source and object of knowledge claims. In this context, New Realism draws on a crucial indispensability thesis: we simply cannot eliminate the standpoint from which humans gather information about human and non-human reality alike from our account of reality itself. In light of this thesis, it turns out that the humanities are fully-fledged contributions to objective knowledge about reality – a fact we cannot ignore without succumbing to illusion. Against this background, the talk concludes that the so-called “scientific worldview” is untenable: it is built upon a denial of knowledge we actually possess, and so, by not being scientific enough, it fails to respect its own premises.
About the speaker:
Markus Gabriel holds the chair in epistemology, modern and contemporary philosophy at the University of Bonn. He is the director of the International Center for Philosophy and the multidisciplinary Center for Science and Thought. With Jocelyn Benoist he also directs Bonn-Paris Center for Research on New Realisms. His work focuses on contemporary philosophy, in particular epistemology and ontology, in an attempt to spell out the consequences of various trends in philosophy in a conversation with the humanities. Currently, he is working on a book called Fictions which deals with topics at the intersection of philosophy, literary studies and sociology.
The NYU Department of German and Deutsches Haus at NYU present “Objectivity and the Humanities – Prospects for a New Realism,” a talk by Professor Markus Gabriel.

The NYU Center for Bioethics is pleased to welcome submissions of abstracts for its 1st Annual Philosophical Bioethics Workshop, to be held at NYU on Friday, April 3, 2020.
We are seeking to showcase new work in philosophical bioethics, including (but not limited to) neuroethics, environmental ethics, animal ethics, reproductive ethics, research ethics, ethics of AI, data ethics, and clinical ethics.
Our distinguished keynote speaker will be Frances Kamm.
There will be four additional slots for papers chosen from among the submitted abstracts, including one slot set aside for a graduate student speaker. The most promising graduate student submission will be awarded a Graduate Prize, which includes coverage of travel expenses (up to $500, plus accommodation for two nights) as well as an award of $500. Please indicate in your submission email whether you would like to be considered for the Graduate Prize.
Please submit extended abstracts of between 750 and 1,000 words to philosophicalbioethics@gmail.com by 11:59 pm EST on Friday, January 24, 2020. Abstracts should be formatted for blind review and should be suitable for presentation in 30-35 minutes. Notification of acceptance will take place via email by Friday, February 14, 2020.
When submitting your abstract, please also indicate whether you would be interested in serving as a commentator in the event that your abstract is not selected for presentation. We will be inviting four additional participants to serve as commentators.
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.

Individuals support forms of domination with varying levels of understanding that they are doing so. In many cases, those very structures of domination distort our conceptions of them through mechanisms such as motivated reasoning, implicit bias, affected ignorance, false consciousness, and belief polarization. These various epistemic distortions, in turn, cause social conflict, notably by promoting political polarization. Those worried by social conflict have spent a great deal of energy decrying the increasingly polarized contexts in which we live. However, epistemic distortions in our sociopolitical beliefs also misrepresent, maintain systems of domination and prevent human needs from being met.
This workshop aims to go beyond pronouncements such as ‘we are polarized’ or that ‘partisanship is on the rise,’ and begin to think through epistemic distortions at the individual and intersubjective levels, the role of criticism and critique in facilitating belief and social change, and the idea of reconciliation, by asking questions such as:
- In what ways are individual beliefs about domination/social structures epistemically distorted?
- What explains why social beliefs are epistemically distorted?
- What are the normative upshots of epistemic distortion for social relationships like allyship, comradeship, and friendship?
- Ought polarization be remedied? Which epistemic resources and theoretical frameworks avail themselves of emancipatory potential?
Convenors
Ege Yumuşak is a philosopher, specializing in epistemology, the philosophy of mind, and social & political philosophy. She received a PhD in Philosophy from Harvard University in 2022. Her research examines political disagreement—its material foundations, psychological and social manifestations, and epistemic properties. She is currently writing a series of articles on the nature and significance of clashes of perspective in social life.
Nicolas Côté is a postdoctoral researcher at the University of Toronto. His research is mainly in normative ethics and social choice theory, but they also dabble in applied ethics and issues of practical rationality. Côté’s doctoral dissertation work focuses on the measurement of freedom, especially on axiomatic approaches to the measurement question, and on how deontic concerns for protecting individual rights interact with welfarist concerns for improving the general welfare. Côté’s current research focuses on the ethics of decision-making under radical uncertainty.
