In A Human Approach to World Peace is not complicated or even unusual. In fact, it is almost radical in its simplicity. His Holiness feels that science and technology are indeed remarkable but alone are not enough to bring progress and contentment. We are all members of the same human family, and unless we develop a sense of universal responsibility and learn to see each other as brothers and sisters, there can never be world peace. And, above all, His Holiness urges world leaders to meet in this way.' We need a revolution', he says, "in our commitment to humanitarian values."
