Famous quotes containing the word period:
“It is as if, to every period of history, there corresponded a privileged age and a particular division of human life: youth is the privileged age of the seventeenth century, childhood of the nineteenth, adolescence of the twentieth.”
—Philippe Ariés (20th century)
