The logical structure of the world

Abstract This chapter argues that ordinary physical objects stand in relations, with ground-consequent dependencies, and that these objects and relations admit of vague boundaries — all as in an abstract KF-structure. However, given our best understanding of quantum mechanics, the world in the small doesn't consist of spatiotemporal objects of the usual sort, and even the bare notion of an individual object is problematic; similar troubles arise for properties and relations and ground-consequent dependencies. Thus, the Second Philosopher fine-tunes the first component of her account to read: a rudimentary logic is true of the world insofar as it is a KF-world, and in many but not all respects, it is.
