When humans act like animals, they become the most dangerous of animals to themselves and other humans, and this is because of another critical difference between humans and animals: Whereas animals are usually restrained by the limits of physical appetites, humans have mental appetites that can be far more gross and capacious than physical ones. Only humans squander and hoard, murder and pillage because of notions.

The real work of planet-saving will be small, humble, and humbling, and (insofar as it involves love) pleasing and rewarding. Its jobs will be too many to count, too many to report, too many to be publicly noticed or rewarded, too small to make anyone rich or famous.

Perhaps it is to prepare to hear some day the music of the spheres that I am always turning my ears to the music of streams. There is indeed a music in streams, but it is not for the hurried. It has to be loitered by and imagined. Or imagined toward, for it is hardly for men at all. Nature has a patient ear. To her the slowest funeral march sounds like a jig. She is satisfied to have the notes drawn out to the lengths of days or weeks or months. Small variations are acceptable to her, modulations as leisurely as the opening of a flower.

Under the discipline of unity, knowledge and morality come together. No longer can we have that paltry 'objective' knowledge so prized by the academic specialists. To know anything at all becomes a moral predicament. Aware that there is no such thing as a specialized effect, one becomes responsible for judgments as well as facts. Aware that as an agricultural scientist he had 'one great subject,' Sir Albert Howard could no longer ask, What can I do with what I know? without at the same time asking, How can I be responsible for what I know?

Eating is an agricultural act. Eating ends the annual drama of the food economy that begins with planting and birth. Most eaters, however, are no longer aware that this is true. They think of food as an agricultural product, perhaps, but they do not think of themselves as participants in agriculture. They think of themselves as 'consumers.'

To hear of a thousand deaths in war is terrible, and we 'know' that it is. But as it registers on our hearts, it is not more terrible than one death fully imagined.
