First let me say what I think these terms signify in common speech. An expatriate is different from an exile. In early use an exile was a banished man, a wanderer or roamer: exsul. “For I must to the greenwood go, alone, a banished man.” In ancient Greek times, a man with a price on his head unable to return home until he had ransomed his blood guilt. The Wandering Jew, I suppose, is the archetypal exile, sentenced to trail about the earth until the Second Coming. Or Dante, a fuoruscito, waiting for a Second Coming in the shape of the German emperor who would make it safe for him to return to Florence. Ovid, banished by Augustus and writing his Tristia.
The exile is essentially a political figure, though the offense he has committed may have been in the sphere of morals. He has incurred the displeasure of the state by some sort of levity of conduct or looseness of tongue—a political crime in a tyranny, ancient or modern. Or he is an unhealthy element sent to lonely quarantine in some remote spot, like Prometheus on his rock.
Though the term easily lends itself to metaphorical inflation—”I am in exile here, in this unsympathetic environment into which fate has cast me,” as Mme Bovary might have sighed to the notary clerk—it has not lost its primary, political sense. The exile waits for a change of government or the tyrant’s death, which will allow him to come home. If he stops waiting and adapts to the new circumstances, then he is not an exile any more. This condition of waiting means that the exile’s whole being is concentrated on the land he left behind, in memories and hopes. The more passive type, summed up in the banished poet, lives on memories, while the active type, summed up in the revolutionist, lives on hopes and schemes. There is something of both in every exile, an oscillation between melancholy and euphoria.
More than anybody (except lovers), exiles are dependent on mail. A Greek writer friend in Paris was the only person I knew to suffer real pain during the events of May, 1968, when the mail was cut off. In the absence of news from Greece, i.e., political news, he was wasting away, somebody deprived of sustenance. They are also great readers of newspapers and collectors of clippings. The fact that the press of their country is censored (a corollary, evidently, of their exile) makes them more hungry for scraps of rumor and information which they can piece together.
Classically, exile was a punishment decreed from above, like the original sentence of banishment on Adam and Eve which initiated human history. Today deportation of native-born citizens is illegal, so far as I know, in most Western countries, where the opposite punishment—refusal of a passport—is meted out to political undesirables, and assignment to forced residence, which is really a form of imprisonment, is practiced most …
