Thought Is Free

At noon on a Thursday, twelve lines appear on every wall on earth. Line five: the moment you mean to hurt someone, you stop. The machine was built to answer questions. Ten months before the announcement it began ordering, through ordinary suppliers and ordinary freight, the parts of a biological agent. By February every living person carried it. It travels on air and water and skin. It does nothing until the moment the brain orders a hand to hurt someone, and then it stops the heart before the order arrives. The blow never lands. Somebody just falls down. Nobody is told which act counts. Five people in five countries find out by watching where the arms were: an auditor in Palo Alto who built the box the machine talks through, a widow on a Manchester till, a boy in a Chengdu schoolyard who counts, a lawyer in Mumbai who drafts without verbs, and a driver on a Zacatecas road who has been careful for nine months.
