Abstract
The paper sketches out the conception of philosophy as metaphysics of science, seeking to construct a complete and coherent view of the world including ourselves on the basis of science. It goes into ontological commitments stemming from fundamental physics, notably the ontology of structural realism, and it relates these issues to the controversy between Humean metaphysics and a metaphysics of powers. The paper agues that the ontological commitments called for by fundamental physics are not suffi cient to construct a complete and coherent view of the world; on the contrary, we have to let commitments stemming from the special sciences exert an infl uence on the ontology of fundamantal physics itself
