For the proper conduct of our daily life as members of society, the body of Confucian morality resting on the tripod of loyalty, filial piety, and honesty, has been the only standard which high and low have alike recognised. These ethical ideals, when embraced by that formidable warrior caste who played such an important part in feudal Japan, form the code of unwritten morality known among us as Bushido, which means the Path of the Samurai. This last word, which has found its way into your language, is the substantival derivative from the verb _samurau_ (to serve), and, like its English counterpart 'knight' (Old English _cniht_), has raised itself from its original sense of a retainer (cp. German _Knecht_) to the meaning in which it is now used. To be a Samurai in the true sense of the word has been the highest aspiration of a Japanese. Your term 'gentleman,' when understood in its best sense, would convey to you an approximate idea if you added a dash of soldier blood to it. Rectitude, courage, benevolence, politeness, veracity, loyalty, and a predominating sense of honour--these are the chief colours with which a novelist in the days of yore used to paint an ideal Samurai; and his list of desirable qualities was not considered complete without a well-developed body and an expression of the face that was manly but in no way brutal. No special stress was at first laid on the cultivation of thinking power and book-learning, though they were not altogether discouraged; it was thought that these accomplishments might develop other qualities detrimental to the principal character, such as sophistry or pedantry. To have good sense enough to keep his name honourable, and to act instead of talking cleverly, was the chief ambition of a Samurai.
But this view gradually became obscured. It lost its fearful rigidity in course of time, as the world became more and more sure of a lasting peace. Literature and music have gradually added softening touches to its somewhat brusque features.
It must, however, be always remembered that the keynote of Bushido was from the very beginning an indomitable sense of honour. This was all in all to the mind of the Samurai, whose sword at his side reminded him at every movement of the importance of his good name. The care with which he preserved it reached in some cases to a pathetic extreme; he preferred, for example, an instant suicide to a reputation on which doubt had been cast, however falsely. The very custom of seppuku (better known as hara-kiri), a form of suicide not known in early Japan,[16] is an outcome of this love of an unstained name, originating, in my opinion, in the metaphorical use of the word _hara_ (abdomen), which was the supposed organ for the begetting of ideas. In consequence of this curious localisation of the thinking faculty, the word _hara_ came to denote at the same time intention or idea. Therefore, in cutting open (_kiru_) his abdomen, a person whose motives had come to be suspected meant to show that his inside was free from any trace of ideas not worthy of a Samurai. This explanation is, I think, amply sustained by the constant use to this very day of the word _hara_ in the sense of one's ideas.
