Milbank again: “thought, as Eckhart also pointed out, is a kind of jullity precisely because (after Augustine) it is intentional.  To think something is kenotic - it is to let that thing be and not to try to be that thing, even not to try to be oneself when thinking oneself.  Hence we can see color only if our eye is colorless, come to know something only if our mind goes blank and receptive.”
