[catalogued under 12. Knowledge Sources / A. A Priori Knowledge / 5. A Priori Synthetic]

Full Idea

Through intuition we can only know objects as they appear to us (to our senses), not as they may be in themselves; and this presupposition is absolutely necessary if synthetic propositions a priori are to be granted as possible.

Gist of Idea

A priori synthetic knowledge is only of appearances, not of things in themselves

A Reaction

This idea is basic to understanding Kant, and especially his claim that arithmetic is a priori synthetic.
