“We talked of the education of children; and I asked him what he thought was best to teach them first. JOHNSON. “Sir, it is no matter what you teach them first, any more than what leg you shall put into your breeches first. Sir, you may stand disputing which is best to put in first, but in the mean time your breech is bare. Sir, while you are considering which of two things you should teach your child first, another boy has learnt them both.”
—Samuel Johnson (1709–1784)
