Ceux qui ne peuvent se souvenir du passé sont condamnés à le répéter. - George Santayana

Most men's conscience, habits, and opinions are borrowed from convention and gather continual comforting assurances from the same social consensus that originally suggested them.

….ideal goods cannot be assimilated without some training and leisure. Like education and religion they are degraded by popularity, and reduced from what the master intended to what the people are able and willing to receive. So pleasing an idea, then, as this of diffused ideal possessions has little application in a society aristocratically framed; for the greater eminence the few attain the less able are the many to follow them. Great thoughts require a great mind and pure beauties a profound sensibility. To attempt to give such things a wide currency is to be willing to denaturalise them in order to boast that they have been propagated. Culture is on the horns of this dilemma: if profound and noble it must remain rare, if common it must become mean.

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. In the first stage of life the mind is frivolous and easily distracted; it misses progress by failing in consecutiveness and persistence. This is the condition of children and barbarians, in which instinct has learned nothing from experience.
