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.
Convergence to the truth is viewed with some ambivalence in philosophy of science. On the one hand, methods of inquiry that lead to the truth in the limit are prized as marks of scientific rationality. But an agent who, by using some method, expects to always converge to the truth seems to fail a minimum standard of epistemic modesty. This point was recently brought home by Gordon Belot in his critique of Bayesian epistemology. In this paper I will study convergence to the truth theorems within the framework of Edward Nelson’s radically elementary probability theory. This theory provides an enriched conceptual framework for investigating convergence and gives rise to an appropriately modest from of Bayesianism.

Efforts to diversify philosophy, at the curricular level, often focus on increasing the content covered in a semester: i.e., making room for more women on the syllabus, making room for more non-Western texts and thinkers, etc. Similarly, efforts to diversify philosophy, at the professional level, often focus on making room for marginalized topics and/or members of under-represented groups at conferences, in anthologies, and among faculty (both in terms of demographics and research specializations). This all serves to create an antagonistic situation where marginalized voices must fight to be heard and those in the discipline must make “tough choices” about where to cede precious resources such as syllabus space, publication credits, and faculty hires. I suggest that part of the antagonism, at least in the case of Asian philosophy, arises because we are trying to fit non-European texts and thinkers into disciplinary structures that are themselves designed to accommodate a Eurocentric model for philosophy. By “disciplinary structures” I mean the philosophical canon and historical narrative as well as departmental course offerings, curricular requirements for majors and minors, classroom pedagogical practices, and academic research methodologies. Truly transformative change must take place at the structural level. In this brief talk, I consider the scope of such changes, in concrete terms, and raise questions about the effects these changes would have on the disciplinary identity of philosophy as we know it today.

This paper is on the topic of deliberative autonomy in (primarily) post-classical Chinese moral epistemology. By “deliberative autonomy,” I mean the epistemic state or achievement in which one’s ethical views or beliefs are those that seem right to oneself and are based on reasons or considerations that one understands for oneself. This is to be contrasted with holding a view or belief based primarily on the authority or expertise of others, without seeing for oneself that the view is correct or why it is correct. The Chinese philosophical tradition is rich in discussion of the nature, value, and function of deliberative autonomy, having much to say both in its defense and against it. I will focus my discussion by looking more closely at what Neo-Confucians have said about a particular term of art, zide 自得 (“getting it oneself”). I translate and discuss some passages on “getting it oneself” in the works and recorded lessons of influential Song, Ming, and Qing Confucians, note different types of deliberative autonomy implied by these passages, and discuss Wm. Theodore de Bary’s famous explication of “getting it oneself.” I consider whether the premium these Confucians placed on zide has the implications for liberal education that de Bary proposes and describe how proponents of zide could respond to formidable and important Xunzian arguments for deference to traditions and expertise.

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.

The philosophical and psychological literature on well-being tend to focus on the prudential value of positive emotions such as pleasure, joy, or gratitude. But how do the negative emotions such as grief fit into our understanding of well-being? It is often assumed that negative emotions are intrinsically bad far us and that we should work toward eliminating them, especially from the perspective of our own well-being.
In this presentation I want to question this assumption by drawing on the ideas of Zhuangzi (a prominent early Daoist thinker from the 4th Century BCE) to argue that negative emotions are not intrinsically bad for us, and that their prudential value or disvalue is context dependent. Zhuangzi’s outlook, with his focus on the flexibility of perspectives and living according to our natural, spontaneous inclinations, gives us reason to reconsider the role of negative emotions in our lives and how we might think about them in a more constructive way.

In recent decades, “mindfulness” has spread like wildfire in the United States, pervading schools, hospitals, the tech industry, and even Wall Street. Thanks to research by Professor of Medicine Jon Kabat-Zinn, mindful practices such as meditation are increasingly used to address a wide range of social, emotional, and spiritual issues—such as alienation, anger, and depression—as well as a variety of physical conditions—such as cancer recovery and psoriasis. In this talk, I encourage us to get curious about this trend of mindfulness, asking: Who does it benefit? Where did it come from? What does it owe?
Brooklyn Public Philosophers is a forum for philosophers in the greater Brooklyn area to discuss their work with a general audience, hosted by the Brooklyn Public Library. Its goal is to raise awareness of the best work on philosophical questions of interest to Brooklynites, and to provide a civil space where Brooklynites can reason together about the philosophical questions that matter to them.
