How do we live with our deepest differences? In a world torn by religious conflict, the threats to human dignity are terrifyingly real. Some societies face harsh government repression and brutal sectarian violence, while others are divided by bitter conflicts over religion's place in public life. Is there any hope for living together peacefully? Os Guinness argues that the way forward for the world lies in promoting freedom of religion and belief for people of all faiths and none. He sets out a vision of a civil and cosmopolitan global public square, and how it can be established by championing the freedom of the soul—the inviolable freedom of thought, conscience and religion. In particular he calls for leadership that has the courage to act on behalf of the common good. Far from utopian, this constructive vision charts a course for the future of the world. Soul freedom is not only a shining ideal but a dire necessity and an eminently practical solution to the predicaments of our time. We can indeed maximize freedom and justice and learn to negotiate deep differences in public life. For a world desperate for hope at a critical juncture of human history, here is a way forward, for the good of all.
