> Spengler introduces his book as a "Copernican overturning" involving the rejection of the Eurocentric view of history, especially the division of history into the linear "ancient-medieval-modern" rubric. According to Spengler, the meaningful units for history are not epochs but whole cultures which evolve as organisms. He recognizes at least eight high cultures: Babylonian, Egyptian, Chinese, Indian, Mesoamerican (Mayan/Aztec), Classical (Greek/Roman), Arabian, and Western or European. Cultures have a lifespan of about a thousand years of flourishing, and a thousand years of decline. The final stage of each culture is, in his word use, a "civilization".
