Abstract
Microorganisms luxuriate in, plants push through, the humus, that is, the corpses of plants, insects, birds and mammals. Insects, fish, birds, and mammals nourish themselves with the flesh of plants on hand, and also with that of insects, fish, birds, and mammals. In the natural world, everything assimilates and is assimilated. Every animal, from amoebas to the blue whales, feels moments of fear, for they know they are vulnerable and mortal. As they eat what is at hand they sense that what will eat them is already at hand.
