Tokugawa-era rōnin scholar and strategist Yamaga Sokō (1622-1685) wrote extensively on matters relating to bushidō, bukyō (a "warrior's creed"), and a more general shido, a "way of gentlemen" intended for application to all stations of society.
The aging Tsunetomo's interpretation of bushidō is perhaps more illustrative of the philosophy refined by his unique station and experience, at once dutiful and defiant, ultimately incompatible with the mores and laws of an emerging civil society.
