By the 1920s, though, Wharton began to question the moral aims of modern science, particularly its ambition to relieve men of pain and suffering. She was distrustful of a "world that believed in panaceas." As she warned one would-be revolutionary, "The evils you rightly satirize will be replaced by others more harmful to any sort of civilized living." This warning would serve as the theme of her Jazz Age novels: The Glimpses of the Moon (1922), Twilight Sleep, and The Children (1928). In each, she would depict a set of free-thinking moderns who believe they have "settled in advance all social, religious and moral problems," yet still come "to grief over the same old human difficulties."
