In the current issue of Plough Ben Quash explains an idea he calls mystical empiricism:
The empiricism bit is looking at the world and its objects, its creatures, with intense attention. Not idealizing them but looking at them as they are. And it’s mystical because precisely in that close attention to the very particularities of things, you find yourself suddenly feeling yourself to be in touch with ultimacy, with grace, with divine self-communication. These creatures are conduits of God’s presence and purpose, precisely in their unique particularities. Observation of them becomes a sort of mystical form of encounter with the divine.
That’s a term I’d been groping for.
