"Nature is flexible and resilient. Nature likes redundancy and dispersion. It is approximate and deals in gradients. All boundaries are permeable. Nature nests small systems like molecules within larger systems like cells, which in turn are nested in systems called organs, organisms, ecosystems. We grew from ancient one-celled ancestors. Nature likes mergers: we contain multitudes of other life forms within us. We stand at the crest of four billion years, bacteria molded into wondrous form, burning with a slow fire and about to take the next step."
