Note 11 — THE BRITISH QUARTERLY REVIEW. JULY, 1871.
Reading edition
The terms à priori and à posteriori are misleading. Arguments called à priori are usually mixed, and involve elements strictly à posteriori: experiential facts are inlaid within them. And the proof à posteriori ascends (if it ascends high enough) by the aid of à priori principles. In its rise to the supersensible, it makes use of the noetic principle of the reason.
