A MORE COMPLETE VERSION
OF A WELL-KNOWN QUOTE; "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."
