The character which Bushido stamped on our nation and on the samurai in particular, cannot be said to form "an irreducible element of species," but nevertheless as to the vitality which it retains there is no doubt. Were Bushido a mere physical force, the momentum it has gained in the last seven hundred years could not stop so abruptly. Were it transmitted only by heredity, its influence must be immensely widespread. Just think, as M. Cheysson, a French economist, has calculated, that supposing there be three generations in a century, "each of us would have in his veins the blood of at least twenty millions of the people living in the year 1000 A.D." The merest peasant that grubs the soil, "bowed by the weight of centuries," has in his veins the blood of ages, and is thus a brother to us as much as "to the ox."
