Card 1.5 · Root I — Metaphysics

Philosophy of Space

If every object vanished, would space still be there?

This node asks what space is. Its central dispute is whether space (or spacetime) is a thing in its own right — a container objects sit in — or merely a way of describing the relations between objects; other positions deny that framing, treating space as a form of experience or treating objects themselves as regions of spacetime.

Under I. Metaphysics, beside 1.4 Philosophy of time. Borders 6.11 Philosophy of physics.

The rival answers

Position	Claim
Substantivalism	Space (or spacetime) is an entity, existing independently of the material things it contains
Relationism	Space is nothing but the set of spatial relations among objects
Kantian idealism about space	Space is the a priori form of outer intuition: the form in which objects appear to us, not a property of things as they are in themselves or a relation among them
Supersubstantivalism	Material objects are identified with, constituted by, or derivative from regions of spacetime; on these views spacetime is metaphysically fundamental rather than one substance alongside matter

Key figures

Figure	Dates	Tradition	Contribution
Isaac Newton	1643–1727	European modern	Absolute space; the rotating bucket argument
G. W. Leibniz	1646–1716	European modern	Relationism; space as order of coexistence
Samuel Clarke	1675–1729	European modern	Defended Newton in the Leibniz–Clarke correspondence
Immanuel Kant	1724–1804	European modern	Space as a form of intuition, not a thing
Vaisheshika school	Classical Indian	Indian	Direction (dik), treated as a substance grounding spatial relations such as near and far — distinct from ākāśa and kāla
Zeno of Elea	c. 490–430 BCE	Greek	Paradoxes against plurality and motion (the dichotomy, Achilles) that put pressure on the assumption that space and time are infinitely divisible
