A Priori (n.) has an everyday name — 'already', the word these lectures use more than any other.
A Priori (n.) began as what always already lies at hand before us — from the side of emergence, the earlier.
A Priori (n.) is not what comes first but an addendum — the veil over the fact that being arrives only after the first grab toward beings.

A Priori (n.) is not about knowing (as Kant would have it) but about being.

Conscious awareness always skates along a thin icy crust, one that hides countless deeper layers that are also given to us, but not clearly and openly.
