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.

This conference will discuss the role of digital spaces such as social media in being a public philosopher or theologian. The conference will choose papers that explore different digital platforms, how these platforms can aid in being a public philosopher or theologian, as well as the specific challenges these spaces pose. Sessions will explore how digital spaces have become arenas for philosophers and theologians to discuss ideas with other scholars and with the public, and how the discussion of concepts in this format affects the delivery and reception of the ideas. We will solicit papers that specifically discuss how digital spaces can positively facilitate the goals of public philosophy. Internet spaces are an important tool for the contemporary public philosopher and the full implications of their usage has not yet been fully explored.

This essay tries to develop a “black radical Kantianism” – that is, a Kantianism informed by the black experience in modernity. After looking briefly at socialist and feminist appropriations of Kant, I argue that an analogous black radical appropriation should draw on the distinctive social ontology and view of the state associated with the black radical tradition. In ethics, this would mean working with a (color-conscious rather than colorblind) social ontology of white persons and black sub-persons and then asking what respect for oneself and others would require under those circumstances. In political philosophy, it would mean framing the state as a Rassenstaat (a racial state) and then asking what measures of corrective justice would be necessary to bring about the ideal Rechtsstaat.

In Plato’s Republic, Socrates argues that justice is good not only for its consequences but also in and of itself. Challenged by Glaucon and Adeimantus, who suggest that all human interactions are inherently competitive and that being unjust could help you get the better in these conflicts, Socrates establishes that justice is good because it is harmony in the city and in the soul. If justice is a kind of health of the soul, then surely it is better to be just than unjust. This claim might ameliorate the concerns of Glaucon and Adeimantus, but I will argue that Plato does more than address the vision of justice brought forth by Socrates’ interlocutors. Particularly through the contrasts among the different kinds of lives that are either described or depicted in the Republic, Plato points his readers toward a conception of justice that reveals it as the ground of mutuality, reciprocity, dialogue and friendship. In fact, the Republic reveals justice to be necessary to the philosophical life and, hence, to the best kind of life.
Certain intellectual challenges can neither be resolved by the discovery of missing pieces of information nor by construction of better arguments. Yet what is called for in such cases is not mere persuasion, but a form of intellectual transformation. Wittgenstein sought to respond to the problems of philosophy along similar lines. And the need for the notion of intellectual transformation arises in other contexts, as well, including the context of moral progress, which Cora Diamond explores in her recent work. But various philosophical difficulties stand in the way of embracing the idea that transformation has any role to play when it comes to questions or truth and of value. In particular, it seems that we must either bracket the psychological, historical and anthropological perspectives that the notion of transformation opens up, or else succumb to some form of relativism. My aim in this paper is to show how Wittgenstein and Diamond chart a middle course between these two extremes
