“There was no singles problem until singles got so single-minded that they stopped wasting time with anyone ineligible. Before that, it was understood that one of society's main tasks was matchmaking. People with lifelong friendships and ties to local nonprofessional organizations did not have to fear that isolation would accompany retirement, old age, or losing a spouse. Overburdened householders could count on the assistance not only of their own extended families, but of the American tradition of neighborliness.”

“People often ask, "What is the single most important environmental population problem facing the world today?" A flip answer would be, "The single most important problem is our misguided focus on identifying the single most important problem!”

“Only a woman could make so much out of so little. Give them a single fact and they'd fashion it into a story before taking a single breath.”

“Among the many worlds which man did not receive as a gift of nature, but which he created with his own mind, the world of books is the greatest. Every child, scrawling his first letters on his slate and attempting to read for the first time, in so doing, enters an artificial and complicated world; to know the laws and rules of this world completely and to practice them perfectly, no single human life is long enough. Without words, without writing, and without books there would be no history, there could be no concept of humanity. And if anyone wants to try to enclose in a small space in a single house or single room, the history of the human spirit and to make it his own, he can only do this in the form of a collection of books.”

“This way of leaving your family for work had condemned them over several generations to have their hearts always in other places, their minds thinking about people elsewhere; they could never be in a single existence at one time. How wonderful it was going to be to have things otherwise.”

“God is even in a single parent household.”
