The Elimination of Fields in Classical Physics — •Mario Hubert — University of Lausanne, Switzerland
Newtonian Mechanics was originally formulated as an action-at-a-distance theory. With the advent of electrodynamics in the 19th century, the ontology of physics was enriched by a further entity apart from matter and forces: the electromagnetic field. The idea of fields was then used to make Newton's gravitational theory spatiotemporally local by the introduction of the gravitational field. However, I want to show that classical fields pose philosophical as well as physical problems that encourage to state that they are not entities in space-time. As a result, I want to point out that classical physics only requires substances and properties in the ontology.
