To refrain from meddling, to keep to one’s own affairs. The wisdom of this course of action was observed in ancient times by Plato, Seneca, and others, and even found expression in the Bible (1 Thessalonians 4:11, “Do your own business”). In plain English it was expressed from the sixteenth century on. John Clarke used it in Paroemiologia (1639): “Mind your business.” Among many later writers echoing this sentiment was Lewis Carroll, in one of his enjoyable non sequiturs (Alice’s Adventures in Wonderland, 1865), “‘If everybody minded their business,’ the Duchess said in a hoarse growl, ‘the world would go round a great deal faster than it does.’”
