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.

Since Confucianism is an intergenerational phenomenon, it should have unique insights into ethical issues surrounding our obligations to future generations. In the first part of this discussion, I examine two contemporary Confucian perspectives on intergenerational ethics. Proponents of Confucian Role Ethics have developed an interpretation of xiao 孝 as “intergenerational reverence” that binds the community together over time by reference to shared cultural models and evolving ethical values. The Chinese thinker Jiang Qing in turn argues for a political constitution in which the state depends not just on the will of presently existing citizens, but also serves to preserve and transmit the values of the past for the sake of future generations. While both interpretations share in common a critique of Western individualism and rights-based ethical framework, Jiang’s account of Confucian intergenerationality rests on the authority of tradition, whereas Confucian Role Ethics prioritizes the uniqueness of the situation at hand. In the second half of the discussion, I develop an alternative Confucian approach that is aligned with virtue ethics. On this view, our present virtue is the point of departure for understanding our relations with the past and future. I examine passages in early Confucian texts that suggest a notion of intergenerational virtue, which brings together various dispositions to see our own flourishing as linked with both past and future generations.

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.
The schedule: a short presentation on topic of 3-D Printing, and then Stuart’s presentation for about 1 hr. plus time for questions. It is necessary to register beforehand to be admitted.
CV: Stuart Kurtz graduated from MIT with an SB in Chemical Engineering and from Princeton with an MS degree in Polymer Engineering and an MA and PhD. in Chemical Engineering. He taught at RPI and in Brazil as Professor Titular in Materials Engineering. This was followed by a research career in industry accumulating around 30 patents and publishing at least a few good papers. He now focuses on Philosophy of Science and Physics and climbing mountains because they are there. He has spoken to the Lyceum Society many times; most recently in January, 2018 he spoke on the topic: Lessons from Science Lysenko, Velikovsky and the Demarcation Problem; In February, 2018 he spoke on Geoengineering for Climate Change Mitigation. In December, 2018 he reviewed the Nobel Prize in Physics for that year.

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.

Søren Kierkegaard’s most famous work, Fear and Trembling, has the distinction of drawing near-universal derision from scholars of political theory and ethics. Dr. Dinan suggests that Kierkegaard’s readers haven’t accounted for his return to Socratic political philosophy as a direct riposte to the politics of G.W.F. Hegel and his successors. He considers the implications of Kierkegaard’s use of the ‘questionable stratagem’ of Socratic irony in relation to politics, ethics, Christian faith, and philosophy. Kierkegaard is concerned not with destroying political philosophy, but with restoring its attentiveness to paradox.

“What is Democracy? is the latest movie from Astra Taylor, the world’s foremost philosophy documentarian. It chronicles conversations with middle schoolers, workers, activists, and political philosophers about what democracy is, its promises and pitfalls, and how to strengthen it. On Wednesday, April 17th at 7:00 PM, Taylor is coming to Brooklyn to present a free screening of the film. Afterwards, she will be joined by the political philosopher Nancy Fraser for a discussion of themes from the movie. If you know who either of these people are, you will understand how ridiculously excited I am for this.
As usual, we meet at the Dweck Center at the Grand Army Plaza branch of the Brooklyn Public Library. Here’s the Facebook event. Please note that this event begins at 7:00 PM. Tell and bring everybody.”
