" Ever since he'd given up money, certain people had called him a freeloader, a parasite. (As one comment-thread malapropist put it: "Do you Believe you are smooching off others?") They demanded to know what he was giving back. To which Suelo asked, Who says you need to give something back? What does a raven give? What does a barnacle give, or a coyote? In his view, every living thing gave plenty, merely by existing. But from a strictly materialistic view, his critics had an excellent point. A raven contributes nothing, except of course his own corpse, which will feed some other being. Now Suelo was dying, and he offered his body to the ravens, the coyotes, the ringtails, the mice, the ants. "
