What is Kino's father's position on why Japanese people don't fear death?

His father claims living in the midst of danger helps them know how good life is and makes them brave and strong. This is why their people do not fear death. They see it too often and know that to die sooner or later does not matter. The Japanese are a fortunate people because they live bravely and love life because they live in danger, and they do not fear death because they understand it is a necessary part of life.
