“It is the way of the superior man to prefer the concealment of his virtue, while it daily becomes more illustrious, and it is the way of the mean man to seek notoriety, while he daily goes more and more to ruin.”

Context: Man is constantly being assured that he has more power than ever before in history, but his daily experience is one of powerlessness. … If he is with a business organization, the odds are great that he has sacrificed every other kind of independence in return for that dubious one known as financial.

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.

Darwin Among the Machines
The Note-Books of Samuel Butler (1912), Part III - The Germs of Erewhon and of Life and Habit
Context: Day by day, however, the machines are gaining ground upon us; day by day we are becoming more subservient to them; more men are daily bound down as slaves to tend them, more men are daily devoting the energies of their whole lives to the development of mechanical life. The upshot is simply a question of time, but that the time will come when the machines will hold the real supremacy over the world and its inhabitants is what no person of a truly philosophic mind can for a moment question.
