Concerning the Ultimate Ground of the Differentiation of Directions in Space
Right and left hands reveal an orientational difference not reducible to the internal relations of their parts.
Understanding the text
This essay of 1768 belongs to debates preceding the critical account of space.
Key points
- 01
Incongruence
Two shapes can have corresponding dimensions without being superimposable in the same space.
- 02
Orientation
Right and left reveal a spatial aspect not captured by internal relations alone.
- 03
Development
Kant later used incongruent counterparts within a different theoretical framework.
How to read it
Draw or manipulate symmetrical objects. Compare the 1768 conclusion with the Dissertation and Prolegomena without retrospectively assigning the same theory to all three texts.
