  The paper sets out a primitive ontology of the natural world in terms of
primitive stuff, that is, stuff that has as such no physical properties at all,
but that is not a bare substratum either, being individuated by metrical
relations. We focus on quantum physics and employ identity-based Bohmian
mechanics to illustrate this view, but point out that it applies all over
physics. Properties then enter into the picture exclusively through the role
that they play for the dynamics of the primitive stuff. We show that such
properties can be local (classical mechanics), as well as holistic (quantum
mechanics), and discuss two metaphysical options to conceive them, namely
Humeanism and modal realism in the guise of dispositionalism.
