We show that in the Maxwell–Lorentz theory of classical electrodynamics most initial values for fields and particles lead to an ill-defined dynamics, as they exhibit singularities or discontinuities along light-cones. This phenomenon suggests that the Maxwell equations and the Lorentz force law ought rather to be read as a system of delay differential equations, that is, differential equations that relate a function and its derivatives at different times. This mathematical reformulation, however, leads to physical and philosophical consequences for the ontological status of the electromagnetic field. In particular, fields cannot be taken as independent degrees of freedom, which suggests that one should not add them to the ontology.

I argue that we do not understand gauge theory as well as we think we do, when boundaries are present. I will briefly explain the conceptual and technical issues that arise at the boundary. I will then propose a tentative resolution, which requires us to think of theories not in space-time, but in field-space.

Massimo Pigliucci’s talk has been rescheduled, for personal reasons outside of his control. It will be rescheduled for a later date: here.

Science is by far the most powerful approach to the investigation of the natural world ever devised. Still, it has limits, and there are many areas and questions where the scientific approach is ill suited, or at best provides only pertinent information rather than full answers. The denial of this modest attitude about science is called scientism, which declares science to be the only form of human knowledge and understanding, attempting to subsume everything else, including all the humanistic disciplines, into “science” very broadly (mis-)construed. In this talk, I argue that this is a mistake, and that it moreover has the potential to undermine public trust in science itself.

Upcoming Metro Area Philosophers Talks

===============================================================

What are laws of nature? The predominant view in contemporary philosophy of science is the Humean `best system account’ which holds that the laws of nature are merely descriptive, an efficient summary of contingent regularities that we find in the world. Using the concept of typicality, I will spell out a common anti-Humean intuition into a precise argument: A typical Humean world wouldn’t have any law-like regularities to begin with. Thus (I will argue), Humean metaphysics do not fit the objective order that we find in our universe.

When we’re asked to give examples of philosophical questions, we’re likely to think of questions that are very, very old. Is the physical world all there is? How should I live? How do we know what we know? But some philosophical problems are quite new, made possible or urgent by new developments in science and culture. These are often the most exciting problems to think through.

On March 7th at 7:30 PM, Derek Skillings joins Brooklyn Public Philosophers to share his work on the philosophical consequences of the fact that we are holobionts – biological units composed of hosts and their associated swarms of microorganisms. If you’re interested in health, the problem of personal identity, the philosophy of biology in general, or the philosophical consequences of the fact that we’re made up of a bunch of little things which are themselves alive in particular, you’ll want to check this one out. Here’s the abstract:

“I, holobiont. Are you and your microbes a community or a single entity?”

You are a holobiont – a biological unit made up of a host and its associated microbiome (bacteria, protists, viruses and other microscopic entities). What consequences does this have for how we understand ourselves and other similar organisms? What are our spatial and temporal boundaries, and what does it mean to be a healthy holobiont? In this talk I will look at some alternatives for making sense of both holobiont individuality and “healthy holobiont/microbiome” talk. I will argue that existing accounts of human health are not appropriate for microbiomes, and that notions of ecosystem health face similar shortcomings. I will end by looking at some possibilities for understanding overall host health given the importance and ubiquity of microbiomes.

As usual, we meet at the Dweck Center at the Grand Army Plaza branch of the Brooklyn Public Library. Here’s the Facebook event! Tell everyone, please!

John Dewey, in his resistance to foundational individualism, declares that individual autonomy so conceived is a fiction; for Dewey, it is association that is a fact. In his own language: “There is no sense in asking how individuals come to be associated. They exist and operate in association.” In a way that resonates with Confucian role ethics, the revolutionary Dewey particularizes the fact of associated living and valorizes it by developing a vision of the habitude of unique, defused, relationally-constituted human beings. That is, he develops a distinctive, if not idiosyncratic language of habits and “individuality” to describe the various modalities of association that enable human beings to add value to their activities and to transform mere relations into a communicating community.

In Confucian role ethics, Dewey’s contention that association is a fact is restated in a different vocabulary by appealing to specific roles rather than unique habitudes for stipulating the specific forms that association takes within lives lived in family and community—that is, the various roles we live as sons and teachers, grandmothers and neighbors. For Confucianism, not only are these roles descriptive of our associations, they are also prescriptive in the sense that roles in family and community are themselves normative, guiding us in the direction of appropriate conduct. Whereas for both Confucianism and Dewey, mere association is a given, flourishing families and communities are what we are able to make of our facticity as the highest human achievement.
