"The second observation is that poetry is a universal human art. Despite post-modern theories of cultural relativism that assert there are no human universals, there exists a massive and compelling body of empirical data, collected and documented by anthropologists, linguists, and archeologists that demonstrates there is no human society, however isolated, that has not developed and employed poetry as a cultural practice. Most of this poetry, of course, has been oral poetry. Many of these cultures never developed writing. But the fact remains—and it is a demonstrable fact, not mere opinion—that every society has developed a special class of speech, shaped by apprehensible patterns of sound, namely, poetry" (9-10).
