“Schooling, which we engage in and which supposedly creates equal opportunities, has become the unique, never-before-attempted way of dividing the whole society into classes. Everybody knows at which level of his twelve or sixteen years of schooling he has dropped out, and in addition knows what price tag is attached to the higher schooling he has gotten. It's a history of degrading the majority of people.”

"Printing and Paper Making" in The Common School Journal Vol. V, No. 3 (1 February 1843)
Context: Every school boy and school girl who has arrived at the age of reflection ought to know something about the history of the art of printing, papermaking, and so forth. … All children will work better if pleased with their tools; and there are no tools more ingeniously wrought, or more potent than those which belong to the art of the printer. Dynasties and governments used to be attacked and defended by arms; now the attack and the defence are mainly carried on by types. To sustain any scheme of state policy, to uphold one administration or to demolish another, types, not soldiers, are brought into line. Hostile parties, and sometimes hostile nations, instead of fitting out martial or naval expeditions, establish printing presses, and discharge pamphlets or octavoes at each other, instead of cannon balls. The poniard and the stiletto were once the resource of a murderous spirit; now the vengeance, which formerly would assassinate in the dark, libels character, in the light of day, through the medium of the press.
But through this instrumentality good can be wrought as well as evil. Knowledge can be acquired, diffused, perpetuated. An invisible, inaudible, intangible thought in the silent chambers of the mind, breaks away from its confinement, becomes imbodied in a sign, is multiplied by myriads, traverses the earth, and goes resounding down to the latest posterity.

Hagakure (c. 1716)
Context: A certain swordsman in his declining years said the following: In one's life. there are levels in the pursuit of study. In the lowest level, a person studies but nothing comes of it, and he feels that both he and others are unskillful. At this point he is worthless. In the middle level he is still useless but is aware of his own insufficiencies and can also see the insufficiencies of others. In a higher level he has pride concerning his own ability, rejoices in praise from others, and laments the lack of ability in his fellows. This man has worth. In the highest level a man has the look of knowing nothing. These are the levels in general;. But there is one transcending level, and this is the most excellent of all. This person is aware of the endlessness of entering deeply into a certain Way and never thinks of himself as having finished. He truly knows his own insufficiencies and never in his whole life thinks that he has succeeded. He has no thoughts of pride but with self-abasement knows the Way to the end. It is said that Master Yagyu once remarked, "I do not know the way to defeat others, but the way to defeat myself." Throughout your life advance daily, becoming more skillful than yesterday, more skillful than today. This is never-ending.
