BEWARE OF ORACLES! Ancient Judaism was big on them: oracles from the Sibyl; from the Teacher of Righteousness; from biblical prophets like Abraham, Enoch, Moses, Ezra, and Baruch; from later prophets like Jesus, Jesus ben Ananiah, and Josephus. Philo found oracles everywhere. Early Christians liked them too. Lots of people like them today. Some still produce them.

Michael Dirda reviews THE ROAD TO DELPHI: The Life and Afterlife of Oracles by Michael Wood in the Washington Post (via Arts and Letters Daily). Excerpts:

The pythias, or priestess, at Delphi told Croesus that if he attacked the Persians he would destroy a great empire. Having found the oracle accurate in the past, Croesus went to war and was defeated. The great empire he would destroy was his own.

Oracles, as Michael Wood reminds us in this surprisingly wide-ranging meditation, deal in ambiguity and equivocation, the kind of double-speech technically known as amphibology. That is, oracles tell the truth, but in such a way that we don't see it. As Wood writes, "We hear what we hope for and get what we fear."

I'm particularly fond of Wood's discussion of what he calls "slither," the way that language can squirm out of its apparent meaning, i.e., "None of woman born will harm Macbeth" seems to say one thing and in fact means quite another.

"In that slither an open promise becomes a closed prophecy. I want to suggest that this is how prophecy typically works and also that this motion meets a very particular human need, what we might call a pathology of promising. Promises are kept, but promises are also often not kept, and we need to be prepared for this eventuality. The pathology arises when a promise is manifestly not kept but we can't bring ourselves to believe this. Our favorite strategy in this situation is to reinterpret the promise so that what looked like its breaking was a hasty illusion; on reinterpretation we see the promise has been kept after all, we have not been betrayed. Whose promises do we cling to in this way? Those of God or the gods, of our parents and loved ones; those of anyone whose reliability is more important to us than any truth contained in their apparent defection."

The consequences of such misunderstanding can be terribly unjust. Wood notes that oracles are repeatedly cruel, toying as gods will with people (and as wanton boys do with flies). But why is this? Do the deities wish to teach us self-reliance the hard way? In the last sentence of his book, Wood writes: "The gods appear whenever we think we know more than a human creature ordinarily could, and they disappear again when we turn to ask them what to do." Yet, as all of us know, in moments of crisis and indecision, we look desperately for signs. Christians open their Bibles at random ("Tolle, lege"), and the waffling set up conditions: "If he calls tonight, I'll leave my husband; if he doesn't, I'll stay in the marriage." But this clearly moves us away from "oracle theory," which is based on language and organized ritual, to the realm of what one might call omens. We can see omens anywhere, but they are univocal -- we only pay attention to those that give us the answers we secretly want. And not always to them.
