The irrational in the human has something about it altogether repulsive and terrible, as we see in the maniac, the miser, the drunkard or the ape.
George SantayanaProgress, 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.
George SantayanaPoetry is an attenuation, a rehandling, an echo of crude experience; it is itself a theoretic vision of things at arm's length.
