Once, the governing human metaphor was pastoral or agricultural, and it clarified, and so preserved in human care, the natural cycles of birth, growth, death, and decay. But modern humanity's governing metaphor is that of the machine. Having placed ourselves in charge of creation, we began to mechanize both the creation itself and our conception of it. We began to see the whole creation merely as raw material, to be transformed by machines into a manufactured Paradise.
