« Ceux qui ne peuvent se souvenir de leur passé sont condamnés à le répéter »

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. Those who cannot remember the past are condemned to repeat it.
