Dear Colleagues, Our next meeting will run from 14:15-15:45 on the date indicated in E341 of the main university building. Radin Dardashti will lead discussion on the topic of "Modality and Classical Physics," the reading for which will be the following: 1. J. Butterfield. "David Lewis Meets Hamilton and Jacobi," Philosophy of Science 71, 2004, 1095-1106. 2. J. Butterfield. "Some Aspects of Modality in Analytical Mechanics," in Formale Teleologie und Kausalitat in der Physik, 2004, eds. P. Weingartner and M. Stoeltzner, Mentis, 160-198. (To download, see http://arxiv.org/abs/physics/0210081.) These correspond to papers 10.1 and 10.2 on the "Possible Topics" handout. Please contact me if you have trouble downloading copies of these articles. I should mention that Jeremy says that the first paper is a precis of the first part of the second paper, so the main focus should be on the second. Also, as a reminder, for our two January meetings we will discuss topic 7, "The Principle of Least Action and Dispositions," with discussion led by Karim and Michael S. Best wishes, ~Sam
