Book excerpt: The title is the author's symbol for the central problem of today's world: the violence of poverty which keeps over two-thirds of the world's people in a sub-human condition, the violence of revolt when peaceful demands have no effect and the violence of repression with which the powerful try to crush the demands of the poor. The only escape from this spiral is to bring about justice, and this book is an appeal to all men of good will to exercise 'liberating moral pressure' to redress the balance between the developed and underdeveloped countries and between the privileged and underprivileged in the rich countries.
