Abstract

From two not very controversial premises I argue for a variant of transcendental idealism: Space is a non-conceptual system of particular distances and directions. As a possible object of propositional truth, distance or size is relational. But means the collapse of : In relationally equivalent worlds, one cannot distinguish between particular and conceptual size. What is needed for particular distance being an objective property of things is a global measure of such worlds. This is supplied by rational, indexical agency.
