Famous quotes containing the word congenital:
“A society in which adults are estranged from the world of children, and often from their own childhood, tends to hear children’s speech only as a foreign language, or as a lie.... Children have been treated ... as congenital fibbers, fakers and fantasisers.”
—Beatrix Campbell (b. 1947)
“France is not poetic; she even feels, in fact, a congenital horror of poetry. Among the writers who use verse, those whom she will always prefer are the most prosaic.”
—Charles Baudelaire (1821–1867)
