How philosophy came to disdain the wisdom of oral cultures
A poet, somewhere in Siberia, or the Balkans, or West Africa, some time in the past 60,000 years, recites thousands of memorised lines in the course of an evening. The lines are packed with fixed epithets and clichés. The bard is not concerned with originality, but with intonation and delivery: he or she is perfectly attuned to the circumstances of the day, and to the mood and expectations of his or her listeners.
