Some questions of interpretation
“By the approach through abnormality we have succeeded in penetrating most deeply into the darkness of human nature … The literary person should be the last person to be surprised at this fact. Sooner might he be surprised that he, considering his strong generally and individual tendency, should have so late become aware of the close sympathetic relations which connected his own existence with psychoanalytic research and the life-work of Sigmund Freud. I realized this connection only at a time when his achievement was no longer thought of as merely a therapeutic method, whether recognized or disputed; when it had long since outgrown his purely medical implications and become a world movement which penetrated into every field of science and every domain of the intellect: literature, the history of art, religion and prehistory; mythology, folklore, pedagogy, and what not.”

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.

The Ethics of Belief (1877), The Weight Of Authority
Context: It is hardly in human nature that a man should quite accurately gauge the limits of his own insight; but it is the duty of those who profit by his work to consider carefully where he may have been carried beyond it. If we must needs embalm his possible errors along with his solid achievements, and use his authority as an excuse for believing what he cannot have known, we make of his goodness an occasion to sin.
