One man, one family driven from the land; this rusty car creaking along the highway to the west. I lost my land, a single tractor took my land. I am alone and I am bewildered. And in the night one family camps in a ditch and another family pulls in and the tents come out. The two men squat on their hams and the women and children listen. Here is the node, you who hate change and fear revolution. Keep those two squatting men apart; make them hate, fear, suspect each other. Here is the anlage of the thing you fear. This is the zygote. For here "I lost my land" is changed; a cell is split and from its splitting grows the thing you hate—"We lost our land." The danger is here, for two men are not as lonely and perplexed as one.
