A day, a livelong day, is not one thing but many. It changes not only in growing light toward zenith and decline again, but in texture and mood, in tone and meaning, warped by a thousand factors of season, of heat or cold, of still or multi winds, torqued by odors, tastes, and the fabrics of ice or grass, of bud or leaf or black-drawn naked limbs. And as a day changes so do its subjects, bugs and birds, cates, dogs, butterflies and people.
Visualize yourself confronted with the task of killing, one after the other, a cabbage, a fly, a fish, a lizard, a guinea pig, a cat, a dog, a monkey and a baby chimpanzee. In the unlikely case that you should experience no greater inhibitions in killing the chimpanzee than in destroying the cabbage or the fly, my advice to you is to commit suicide at your earliest possible convenience, because you are a weird monstrosity and a public danger.
