Gabriele Pulcini (New University of Lisbon): From Complementary Logic to Proof-Theoretic Semantics @ Columbia U Philosophy Dept. 716
Mar 8 @ 12:00 pm

Two proof-systems P and P* are said to be complementary when one proves exactly the non-theorems of the other. Complementary systems come as a particular kind of refutation calculi whose patterns of inference always work by inferring unprovable conclusions form unprovable premises. In the first part of my talk, I will focus on LK*, the sequent system complementing Gentzen’s system LK for classical logic. I will show, then, how to enrich LK* with two admissible (unary) cut rules, which allow for a simple and efficient cut-elimination algorithm. In particular, two facts will be highlighted: 1) for any given provable sequent, complementary cut-elimination always returns one of its simplest proofs, and 2) provable LK* sequents turn out to be “deductively polarized” by the empty sequent. In the second part, I will observe how an alternative complementary sequent system can be obtained by slightly modifying the Gentzen-Schütte system G3. I will finally show how this move could pave the way for a novel approach to multi-valuedness and proof-theoretic semantics for classical logic.

Body and Mind in Early China: Embodied Cognition, Digital Humanities, and the Project of Comparative Philosophy- Edward Slingerland (University of British Columbia) @ Columbia University Religion Dept. 101
Mar 8 @ 5:30 pm – 7:30 pm

It is commonly claimed that mind-body dualism is entirely foreign to China—or “the East” more generally. This talk will explore how engaging with the cognitive sciences and digital humanities undermines claims such as this, and more broadly can help us to do our work as scholars of comparative philosophy. Embracing an embodied view of human cognition gets us beyond strong social constructivism and its accompanying cultural essentialism. In addition, new tools from the science and digital humanities can, in combination with traditional archaeological and textual evidence, allow us to more accurately and rigorously assess claims about the philosophical and religious historical record. Specifically, I will focus on novel large-scale textual analysis techniques, online databases for sharing scholarly knowledge, and work in contemporary evolutionary anthropology and cognitive science relevant to the mind-body issue. I will conclude by considering how early Chinese views of mind-body relations do, in fact, differ from some modern Western conceptions, and how taking a more reasonable view of cultural differences can allow us to genuinely learn from other cultures.

Philosophy of Psychology Workshop @ 302 Philosophy Hall, Columbia U
Mar 14 @ 7:00 pm – 9:00 pm

PoPRocks (formerly known as ‘WoPoP’) is an ongoing series in the NYC area for early career researchers – typically grad students, postdocs, people who got their PhD within the last few years, advanced undergrads etc. – working on philosophy of psychology/mind/perception/cognitive science/neuroscience/… . We usually meet roughly once every 2-3 weeks to informally discuss a draft paper by one of our members. Typically presenters send a copy of their paper around 1 week in advance, so do join the mailing list (by emailing poprocksworkshop@gmail.com or one of the organizers) or email to ask for a copy of the paper. We aim for a friendly, constructive discussion with the understanding that the drafts discussed are typically work in progress.

Presenters Spring 2019

All presentations will be on Thursdays at 7-9pm in 302 Philosophy Hall, Columbia University (Morningside Heights Campus).

February 28th – Kate Pendoley (CUNY)

​March 14th – Amogh Sahu (Columbia)

April 18th – Nemira Gasiunas (Columbia)

If anyone else would like to present on other Thursdays, get in touch.

Bjorndahl: The Epistemology of Nondeterminism. Logic, Probability, and Games Seminar @ Faculty House, Columbia U
Mar 29 @ 4:00 pm

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.

Confucian Approaches to Intergenerational Ethics. Timothy Connolly (East Stroudsburg) @ Columbia University Religion Dept. 101
Mar 29 @ 5:30 pm – 7:30 pm

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 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.

Promises and Perils of Neuroprediction @ Faculty House, Columbia U
Apr 16 @ 4:00 pm – 6:30 pm

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.
