Single Idea 9347
[filed under theme 12. Knowledge Sources / A. A Priori Knowledge / 4. A Priori as Necessities
]
Full Idea
One could establish the indispensability of the reality of pure a priori principles for the possibility of experience itself, and thus establish it a priori. Where would experience gets its certainty if it was based on empirical, contingent rules?
Gist of Idea
A priori knowledge is indispensable for the possibility and certainty of experience
Source
Immanuel Kant (Critique of Pure Reason [1781], B005)

A Reaction
[compressed] There seems a touch of circularity here, apart from the transcendental argument. Proving the a priori by a priori means? All very odd. And experience is certain because it is based on a priori rules, which are necessary?
