Humans, like all other creatures, must make a difference; otherwise, they cannot live. But unlike other creatures, humans must make a choice as to the kind and scale of difference they make. If they choose to make too small a difference, they diminish their humanity. If they choose to make too great a difference, they diminish nature, and narrow their subsequent choices; ultimately, they diminish or destroy themselves. Nature, then, is not only our source but also our limit and measure.

We do not need to plan or devise a "world of the future"; if we take care of the world of the present, the future will have received full justice from us. A good future is implicit in the soils, forests, grasslands, marshes, deserts, mountains, rivers, lakes, and oceans that we have now, and in the good things of human culture that we have now; the only valid "futurology" available to us is to take care of those things. We have no need to contrive and dabble at "the future of the human race"; we have the same pressing need that we have always had - to love, care for, and teach our children.

No matter how much one may love the world as a whole, one can live fully in it only by living responsibly in some small part of it. Where we live and who we live there with define the terms of our relationship to the world and to humanity. We thus come again to the paradox that one can become whole only by the responsible acceptance of one's partiality.

You have been given questions to which you cannot be given answers. You will have to live them out - perhaps a little at a time.' And how long is that going to take?' I don't know. As long as you live, perhaps.' That could be a long time.' I will tell you a further mystery,' he said. 'It may take longer.

I could die in peace, I think, if the world was beautiful. To know it's being ruined is hard.

People need to feed themselves, next they need to feed their own communities.
