The great comic artist, Frank Miller, has a very interesting quote about the ronin. He had done extensive research about samurai culture for Daredevil and later on worked on the Ronin comic series.
Frank Miller: “The aspect of the samurai that intrigues me most is the ronin, the masterless samurai, the fallen warrior. … This entire project comes from my feelings that we, modern men, are ronin. We’re kind of cut loose. I don’t get the feeling from the people I know, the people I see on the street, that they have something greater than themselves to believe in. Patriotism, religion, whatever — they’ve all lost their meaning for us.”
