Famous quotes containing the word continuity:
“Continuous eloquence wearies.... Grandeur must be abandoned to be appreciated. Continuity in everything is unpleasant. Cold is agreeable, that we may get warm.”
—Blaise Pascal (16231662)
“Only the family, societys smallest unit, can change and yet maintain enough continuity to rear children who will not be strangers in a strange land, who will be rooted firmly enough to grow and adapt.”
—Salvador Minuchin (20th century)
“The dialectic between change and continuity is a painful but deeply instructive one, in personal life as in the life of a people. To see the light too often has meant rejecting the treasures found in darkness.”
—Adrienne Rich (b. 1929)
