Abstract

In the grand tradition, philosophical ontology was considered logically and epistemologically prior to scientific ontology. Like many contemporary philosophers of science, we consider this to be a mistake. There is two-way traffic between philosophical and scientific ontologies; the more we learn about what there actually is, the more we learn about what can be and what must be, and vice versa. But that is not the present topic; here we focus on the ontology or ontologies of science, not traditional philosophical ontologies or the traffic between scientific and philosophical ontologies.
