Life & Times of Michael K (1983)
Context: He closed his eyes and tried to recover in his imagination the mudbrick walls and reed roof of her stories, the garden of prickly pear, the chickens scampering for the feed scattered by the little barefoot girl. And behind that child, in the doorway, her face obscured by shadow, he searched for a second woman, the woman from whom his mother had come into the world. When my mother was dying in the hospital, he thought, when she knew her end was coming, it was not me she looked to but someone who stood behind me: her mother or the ghost of her mother. To me she was a woman but to herself she was still a child calling to her mother to hold her hand and help her. And her own mother, in the secret life we do not see, was a child too. I come from a line of children without end.

This has often been attributed to de Tocqueville's Democracy in America, but erroneously, according to "The Tocqueville Fraud" http://www.weeklystandard.com/print/the-tocqueville-fraud/article/8100 in The Weekly Standard (13 November 1995). This quote dates back to at least 1922 (Herald and Presbyter, September 6, 1922, p. 8 http://books.google.com/books?id=3sYpAAAAYAAJ&pg=RA3-PT21&vq=%22I+sought+for+the+greatness+and+genius+of+America+in+her+commodious%22&source=gbs_search_r&cad=0_1)
There's an earlier variant, without the memorable ending, that dates back to at least 1886:
I went at your bidding, and passed along their thoroughfares of trade. I ascended their mountains and went down their valleys. I visited their manufactories, their commercial markets, and emporiums of trade. I entered their judicial courts and legislative halls. But I sought everywhere in vain for the secret of their success, until I entered the church. It was there, as I listened to the soul-equalizing and soul-elevating principles of the Gospel of Christ, as they fell from Sabbath to Sabbath upon the masses of the people, that I learned why America was great and free, and why France was a slave.
