“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.”
“Progress is impossible without change; and those who cannot change their minds cannot change anything.”
“Those who cannot remember the past, are condemned to repeat it.”
“If we are bound to improve, we need not trouble to improve. The pure doctrine of progress is the best of all reasons for not being a progressive.”
“It's been my experience, Langford, that the past always has a way of returning. Those who don't learn, or can't remember it, are doomed to repeat it.”
“Those who fail to learn from the past are doomed to repeat it.”
