On arid Anarres, the communities had to scatter widely in search of resources, and few of them could be self-supporting, no matter how they cut back their notions of what is needed for support. They cut back very hard indeed, but to a minimum beneath which they would not go; they would not regress to pre-urban, pre-technological tribalism. They knew that their anarchism was the product of a very high civilization, of a complex diversified culture, of a stable economy and a highly industrialized technology that could maintain high production and rapid transportation of goods. However vast the distances separating settlements, they held to the ideal of complex organicism. They built the roads first, the houses second. The special resources and products of each region were interchanged continually with those of others, in an intricate process of balance: that balance of diversity which is the characteristic of life, of natural and social ecology.
