General Information

This group is a forum for philosophers (faculty members and graduate students) in Southern California to meet and discuss their own research and other recent articles in philosophy of physics. We intend to meet 2-3 times per quarter, with topics determined by the interests of the group.

Unless otherwise noted, meetings will be hosted by the LPS department at UC Irvine, in the LPS seminar room (777 Social Science Tower) [campus map]. For instructions regarding parking and to reserve a permit, contact Patty Jones, LPS Department Manager.

Please contact me (james.owen.weatherall [AT] uci [DOT] edu) if you would like to join the group.

Christopher Gregory Weaver (Illinois, Urbana-Champaign), “Hamilton, Hamiltonian Mechanics, and Causation”

Abstract: I show how Hamilton’s philosophical commitments led him to a causal interpretation of classical mechanics. I argue that Hamilton’s metaphysics of causation was injected into his dynamics by way of a causal interpretation of force. I then detail how forces remain indispensable to both Hamilton’s formulation of classical mechanics and what we now call Hamiltonian mechanics (i.e., the modern formulation). On this point, my efforts primarily consist of showing that the orthodox interpretation of potential energy is the interpretation found in Hamilton’s work. Hamilton called the potential energy function the force-function because he believed that it represents forces at work in the world. Multifarious non-historical arguments for this orthodox interpretation of potential energy are provided, and matters are concluded by showing that in classical Hamiltonian mechanics, facts about the potential energies of systems are grounded in facts about forces. Thus, if one can tolerate the view that forces are causes of motions, then Hamilton provides one with a road map for transporting causation into one of the most mathematically sophisticated formulations of classical mechanics, viz., Hamiltonian mechanics.
