Context: Everyone says, stay away from ants. They have no lessons for us; they are crazy little instruments, inhuman, incapable of controlling themselves, lacking manners, lacking souls. When they are massed together, all touching, exchanging bits of information held in their jaws like memoranda, they become a single animal. Look out for that. It is a debasement, a loss of individuality, a violation of human nature, an unnatural act.
Sometimes people argue this point of view seriously and with deep thought. Be individuals, solitary and selfish, is the message. Altruism, a jargon word for what used to be called love, is worse than weakness, it is sin, a violation of nature. Be separate. Do not be a social animal. But this is a hard argument to make convincingly when you have to depend on language to make it. You have to print out leaflets or publish books and get them bought and sent around, you have to turn up on television and catch the attention of millions of other human beings all at once, and then you have to say to all of them, all at once, all collected and paying attention: be solitary; do not depend on each other. You can’t do this and keep a straight face.
