Famous quotes containing the word life:
“A woman’s whole life is a history of the affections. The heart is her world: it is there her ambition strives for empire; it is there her avarice seeks for hidden treasures. She sends forth her sympathies on adventure; she embarks her whole soul on the traffic of affection; and if shipwrecked, her case is hopeless—for it is a bankruptcy of the heart.”
—Washington Irving (1783–1859)
“Alvina felt herself swept ... into a dusky region where men had dark faces and translucent yellow eyes, where all speech was foreign, and life was not her life. It was as if she had fallen from her own world on to another, darker star, where meanings were all changed.”
—D.H. (David Herbert)
“In soliciting donations from his flock, a preacher may promise eternal life in a celestial city whose streets are paved with gold, and that’s none of the law’s business. But if he promises an annual free stay in a luxury hotel on Earth, he’d better have the rooms available.”
—Unknown. Charlotte Observer (October 6, 1989)
