We are confronted by a closed circle, with the hidden city, with the high garden wall, and with coldness of heart. What is on the other side? And how can we ask? As Socrates says in the Meno, "A man cannot inquire either about that which he knows or about that which he does not know. For if he knows, he has no need to enquire, and if not, he cannot, for he does not know the very subject about which he is to inquire." Plato's puzzle is about knowledge, but the circle is wider still. For example,
"Only he who believes is obedient, and only he who is obedient believes," said Dietrich Bonhoeffer (Nachfolge).
"A Christian is an utterly free man, lord of all, subject to none; A Christian is an utterly dutiful man, servant of all, subject to all," said Martin Luther (De Libertate Christiana).
"Which comes first," asked the young Augustine, "to call upon you or to praise you? To know you or to call upon you? Must we know you before we can call upon you? Anyone who invokes what is still unknown may be making a mistake" (Confessiones 1.1).
I'm still working hard on completing even the first draft of this card. The circle problem is a problem of discipleship, of how one becomes another thing. It is a kind of miracle. It is ontological. It is election. What is the difference between it and creation? Is this card soteriology? Note the quote from Emerson's "Circles": "Everything looks permanent until its secret is known." And Dave Eggers has an essay called "The Circle" about corporate totalitarianism. Note also C. S. Lewis's lecture "The Inner Ring" and its implications for judgment. cf. my response.
