Final answer:
Kant's discussion of pure geometry in the Prolegomena reveals a potential contradiction. Pure geometry has objective reality under the condition of referring to objects of the senses, but Kant also asserts that it is independent of sensory experiences.
Step-by-step explanation:
In Kant's discussion of pure geometry in the Prolegomena, a potential contradiction arises regarding the nature of pure geometry. Kant posits that pure geometry has objective reality only under the condition of referring to objects of the senses, creating a tension between a priori and a posteriori elements. However, Kant maintains that pure geometry is entirely independent of sensory experiences, dismissing any connection to objects of the senses.
