Alison Fernandes: Three Accounts of Laws and Time @ NYU Professional Studies, room 125
Oct 24 @ 4:00 pm – 6:00 pm

Loewer distinguishes two approaches to laws and time: Humean accounts, which deny primitive modality and explain temporal asymmetries in scientific terms, and non-Humean accounts that take temporal asymmetry and modality to be metaphysically fundamental. I’ll argue that Loewer neglects an important third approach: deny metaphysical claims about fundamentality, and explain temporal asymmetries as well as the function of modal entities in scientific terms. This pragmatist approach provides a clear ontology to science, and, and unlike the other two accounts, doesn’t use metaphysics in place of scientific explanation.

There will be dinner after the talk. If you are interested, please send an email with “Dinner” in the heading to nyphilsci@gmail.com (please note that all are welcome, but only the speaker’s dinner will be covered). If you have any other questions, please email isaac.wilhelm@rutgers.edu.

Nielsen: Speed-optimal Induction and Dynamic Coherence @ Faculty House, Columbia U
Nov 16 @ 4:10 pm – 6:10 pm

A standard way to challenge convergence-based accounts of inductive success is to claim that they are too weak to constrain inductive inferences in the short run. We respond to such a challenge by answering some questions raised by Juhl (1994). When it comes to predicting limiting relative frequencies in the framework of Reichenbach, we show that speed-optimal convergence—a long-run success condition—induces dynamic coherence in the short run. This is joint work with Eric Wofsey.

Actual Causality: A Survey, Joseph Halpern (Cornell) @ Faculty House, Columbia U
Dec 7 @ 4:10 pm

What does it mean that an event C “actually caused” event E? The problem of defining actual causation goes beyond mere philosophical speculation.  For example, in many legal arguments, it is precisely what needs to be established in order to determine responsibility.   (What exactly was the actual cause of the car accident or the medical problem?) The philosophy literature has been struggling with the problem of defining causality since the days of Hume, in the 1700s. Many of the definitions have been couched in terms of counterfactuals. (C is a cause of E if, had C not happened, then E would not have happened.) In 2001, Judea Pearl and I introduced a new definition of actual cause, using Pearl’s notion of structural equations to model counterfactuals.  The definition has been revised twice since then, extended to deal with notions like “responsibility” and “blame”, and applied in databases and program verification.  I survey the last 15 years of work here, including joint work with Judea Pearl, Hana Chockler, and Chris Hitchcock. The talk will be completely self-contained.

Game Theory with Mathematics Faculty Member Daniel King @ Wrexham Living Room
Jan 29 @ 7:00 pm – 9:00 pm

Daniel King (BS, Lafayette College. MS, PhD, University of Virginia) is a mathematics scholar with special interests in mathematics education, game theory, history and philosophy of mathematics, and the outreach of mathematics to the social sciences and the humanities. He currently teaches an undergraduate course, Game Theory: The Study of Strategy and Conflict.

In this talk, King will focus on two particularly intriguing “games:” Newcomb’s Problem and the Prisoners’ Dilemma. The analysis of both games leads us to a curious paradox of sorts. Fascinating and perplexing, these games and the paradoxes they unleash serve to challenge some of our most cherished beliefs and philosophical viewpoints. No prior knowledge of game theory (or advanced-level mathematics) is required in order to enjoy and fully engage with the ideas we explore in this talk.

This event is sponsored by Friends of Sarah Lawrence College and is open to the public.

To register for this event, or for more information on the Friends of Sarah Lawrence College, please e-mail friends@sarahlawrence.edu or call 914.323.6154.

Logic, Probability, and Games Seminar @ Faculty House, Columbia U
Feb 8 @ 4:00 pm

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.

Buddha versus Popper: Do we live in the present or do we plan for the future? Rohit Parikh (CUNY) @ Faculty House, Columbia U
Feb 22 @ 4:10 pm

There are two approaches to life. The first one, which we are identifying with Sir Karl Popper, is to think before we act and to let our hypotheses die in our stead when the overall outcome is likely to be negative. We act now for a better future, and we think now which action will bring the best future. Both decision theory and backward induction are technical versions of this train of thought.  The second approach, which we will identify with the Buddha, is to live in the present and not allow the future to pull us away from living in the ever present  Now. The Buddha’s approach is echoed in many others who came after him, Jelaluddin Rumi, Kahlil Gibran, and even perhaps Jesus.  It occurs in many contemporary teachers like Eckhart Tolle and Thich Nhat Hanh.  We may call Popper’s approach “futurism” and the Buddha’s approach “presentism.”

In this talk, we will discuss various aspects of the discourse on presentism and futurism. The purpose is to contrast one with the other. We will not attempt to side with one against the other, and instead leave it as a future project to find a prescriptive action-guiding choice between the two. We merely conjecture that a better optimal choice between these two positions may be somewhere in between. (This is joint work with Jongjin Kim.)

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.

In this context “logic” is broadly interpreted as covering applications that involve formal representations.

Does Time Flow? Stuart Kurtz, PhD @ The New York Academy of Sciences, flr 40
Apr 1 @ 1:15 pm – 3:00 pm

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.

Huttegger: Rethinking Convergence to the Truth. Simon Huttegger (UC Irvine) @ Faculty House, Columbia U
Apr 26 @ 4:10 pm

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.
