From War To Peace
Prior to the Edo period (1600–1868), the primary function of a warrior was to fight. Writing about how to behave as warriors was of less immediate concern than actual battlefield skills. Tokugawa Ieyasu changed all that, through the unification of the country and his establishment of the third and final bakufu in 1603. Suddenly the bushi, who had been engaged in almost continual warfare for one hundred years, were left without any battles to fight. By the eighteenth century, the gap between name and role had widened to the point that the bushi experienced a full-fledged identity crisis. The samurai were now primarily administrators and bureaucrats searching for an understanding of their proper role in a warless age.
Unlike their predecessors, who had been writing for fighting men and clan leaders, thinkers such as Yamaga Sokō and his student Daidōji Yūzan wrote about Bushido in an attempt to define and encourage behaviors that would distinguish warriors from the other classes of farmers, artisans, and merchants. Incorporating a more traditional Confucianism than the state-favored Neo-Confucianism, Yamaga argued that the primary duty of the warrior was to serve as an exemplar for the rest of society, through deeply cultivated sincerity of action.
Yamamoto Tsunetomo, in the Hagakure, saw a very different purpose for the eighteenth-century warrior—"The Way of the Samurai is found in death" (p. 17). This anachronistic view—warriors had not died in battle for more than a century—is frequently misunderstood. In order to control the armed warriors, Tokugawa Ieyasu established a series of inviolable laws; these at times came into conflict with the warrior's individual loyalties or sense of honor. In particular, both parties in any conflict between samurai were to be punished equally; in this context, Yamamoto urged that if warriors were forced to break the Shogun's law they might as well fight to the death.
