What do you see when you look at an animal? A kindred spirit, a creature much like you; but possibly, the very next moment, a beast, a stranger, just an animal. Animals are like those pictures that we see as one thing and then another; the duck that suddenly becomes a rabbit; the wineglass that’s also an old woman in profile. Now the pig is a fellow creature, like Wilbur in Charlotte’s Web. Now he’s pork.
