Progress, far from consisting in change, depends on retentiveness. When change is absolute there remains no being to improve and no direction is set for possible improvement: and when experience is not retained, as among savages, infancy is perpetual.
George SantayanaThere is nothing sacred about convention; there is nothing sacred about primitive passions or whims; but the fact that a convention exists indicates that a way of living has been devised capable of maintaining itself.
