The Critique of Pure Reason, Part 3 summary
Part 3 of 79 · 3 min to read the part
In § 2. Metaphysical Exposition of This Concept Section I. On Space, the speaker argues that space makes external experience possible rather than coming from it.
What happens
- The speaker distinguishes external sense, which presents objects spatially, from internal sense, which presents inner states through time.
- External sensations require an existing representation of space, so experience cannot supply that representation.
- We can imagine space without objects, but cannot imagine its absence; space therefore conditions external appearances.
- Different spaces are restrictions within one encompassing space, and geometry draws its certainty from a priori intuition.
- Space contains infinitely extendable parts, supporting its classification as an intuition rather than a general concept.
