The poet Shelley believed his body would at last be the total and docile servant of his intellect if he ate nothing but leaves and fruit—and I am devoted to Shelley. But I am devoted to Nature too, and to consider Nature without this appetite—this other-creature-consuming appetite—is to look with shut eyes upon the miraculous interchange that makes things work, that causes one thing to nurture another, that creates the future out of the past.
