“If one considers the efforts made by many IALs in order to translate all the masterpieces of world literature, one wonders whether, by using an IAL originally, it is possible to achieve artistic results.
One is tempted to cite a celebrated (if misunderstood) boutade attributed to Leo Longanesi: “You can’t be a great Bulgarian poet.” The boutade is not a nasty comment about Bulgaria: Longanesi wanted to say that one cannot be a great poet if one writes in a language spoken only by a few million people in a country which (whatever else it is) has remained for centuries on the margins of history.
I do not think Longanesi meant that one cannot be a great poet if one writes in a language unknown to the rest of the world.
This seems reductive, for poetic greatness is surely not dependent on diffusion. It seems more likely that Longanesi wanted to say that a language is the sum and consequence of a variety of social factors which, over the course of history, have enriched and strengthened it.
Many of these factors are extra-linguistic: these include provocative contacts with other cultures, new social needs to communicate new experiences, conflicts and renewals within the speaking community.
If that community, however, were a people on the margins of history, a people whose customs and whose knowledge have remained unchanged for centuries; it it were a people whose language has remained unchanged as well, nothing more than the medium of worn-out memories and rituals ossified over centuries; how could we ever expect it to be a vehicle for a great new poet?
But this is not an objection that one could make against an IAL. An IAL is not limited in space, it exists in symbiosis with other languages. The possible risk is rather that the institutional control from above (which seems an essential prerequisite for a successful IAL) will become too tight, and the auxiliary language will lose its capacity to express new everyday experiences.
One could object that even medieval Latin, ossified though it was in the grammatical forms of which Dante spoke, was still capable of producing liturgical poetry, such as the Stabat Mater or the Pange Lingua, not to mention poetry as joyful and irreverent as the Carmina Burana. Nevertheless, it is still true that the Carmina Burana is not the Divine Comedy.
An IAL would certainly lack a historic tradition behind it, with all the intertextual richness that this implies. But when the poets of medieval Sicilian courts wrote in a vernacular, when the Slavic bards sang The Song of Prince Igor and the Anglo-Saxon scop improvised Beowulf, their languages were just as young–yet still, in their own way, capable of absorbing the entire history of the preceding languages.”
