These are remarks about the way we think of the world, about our conceptual scheme. A more recognizably philosophical, though no clearer, way of expressing them would be to say that our ontology comprises objective particulars. It may comprise much else besides.

Part of my aim is to exhibit some general and structural features of the conceptual scheme in terms of which we think about particular things.
