Full Idea
Kant's shift in his understanding of apriority from the content of truth and of proof-sequences of propositions to the character of cognitive procedures opens more possibilities for understanding the sources of apriority, in capacities and mental acts.
Gist of Idea
Kant's shift of view enables us to see a priority in terms of mental capacity, not truth and propositions
