Naturalisierte Metaphysik als Erklärung zweiter Stufe. Wie Metaphysik wissenschaftliche Ontologien erklären kann
(Metaphysik und Ontologie, Englisch)

Laurie Paul (2012) defends naturalized metaphysics claiming that the empirical sciences and naturalized metaphysics share the common method of Inference to the Best Explanation (IBE). The IBE has proven successful in the sciences and since metaphysical IBEs are not fundamentally different, Paul concludes that "if we accept IBE in scientific theorizing, we should accept it in metaphysical theorizing." (Paul 2012, 22)
She conceptualizes the methods of the sciences and of naturalized metaphysics as "running in parallel". In general the method of IBE yields the best explanans for a given explanandum. For Paul, the explananda of scientific and metaphysical IBEs differ and so do the explanantia which are to be determined. While the sciences explain experimental data proposing scientific theories, metaphysics explains our ordinary experience proposing metaphysical theories (cf. Paul 2012, 16).
Against Paul, I argue that the explananda of naturalized metaphysics are scientific ontologies, i. e. the set of a theory's ontological commitments. Thus results of scientific IBEs become an input of metaphysical theorizing and metaphysical explanations are second-level explanations (of scientific ones). Scientific ontologies assume a role for metaphysical theorizing analogous to the role of experimental data for scientific theorizing. The adequacy of metaphysical theories is measured by scientific ontologies but such ontologies underdetermine metaphysical theory-choice so that the method of IBE is to be pursued.
In this picture, the sciences and naturalized metaphysics are more closely linked than Paul suggests. Furthermore, metaphysics inherits inductive risks from the sciences and adds additional risks. This explains why naturalized metaphysics is less certain than the sciences and it confines the impetus of revisionary metaphysics on the sciences.
