“That which we persist in doing becomes easy to do, not that the nature of the thing has changed, but our power to do has increased.”

Nous n'arrivons pas à changer les choses selon notre désir, mais peu à peu notre désir change. La situation que nous espérions changer parce qu'elle nous était insupportable, nous devient indifférente. Nous n'avons pas pu surmonter l'obstacle, comme nous le voulions absolument, mais la vie nous l'a fait tourner, dépasser, et c'est à peine alors si en nous retournant vers le lointain du passé nous pouvons l'apercevoir, tant il est devenu imperceptible.

Introductory : The Problem
Progress and Poverty (1879)
Context: It is true that wealth has been greatly increased, and that the average of comfort, leisure, and refinement has been raised; but these gains are not general. In them the lowest class do not share. I do not mean that the condition of the lowest class has nowhere nor in anything been improved; but that there is nowhere any improvement which can be credited to increased productive power. I mean that the tendency of what we call material progress is in nowise to improve the condition of the lowest class in the essentials of healthy, happy human life. Nay, more, that it is still further to depress the condition of the lowest class. The new forces, elevating in their nature though they be, do not act upon the social fabric from underneath, as was for a long time hoped and believed, but strike it at a point intermediate between top and bottom. It is as though an immense wedge were being forced, not underneath society, but through society. Those who are above the point of separation are elevated, but those who are below are crushed down.

Variant translation: When all your judgements are based on your own wisdom, you tend towards selfishness and fail by straying from the right path. Your own judgements are narrow minded and have no persuasive power or growth for others. It is best to consult a wise man when a fit decision does not occur to you. A wise man is a fair judge from an objective point of view. He is passing judgement for the benefit of others, not for his own sake. A judgement passed using only one's own wisdom is just like thrusting a stick into the ground and expecting it to grow!
Hagakure (c. 1716)
Context: It is difficult for a fool's habits to change to selflessness.... Because we do most things relying only on our own sagacity we become self-interested, turn our backs on reason, and things do not turn out well. As seen by other people this is sordid, weak, narrow and inefficient. When one is not capable of true intelligence, it is good to consult with someone of good sense. An advisor will fulfill the Way when he makes a decision by selfless and frank intelligence because he is not personally involved. This way of doing things will certainly be seen by others as being strongly rooted. It is, for example, like a large tree with many roots. One man's intelligence is like a tree that has been simply stuck in the ground.
We learn about the sayings and deeds of the men of old in order to entrust ourselves to their wisdom and prevent selfishness. When we throw off our own bias, follow the sayings of the ancients, and confer with other people, matters should go well and without mishap.
