"The great problem with trying to retreat into a life of private dignity and saying 'let's make the best of what we've got' is that the world does not stand still. There is a dynamic of development which is leading to more and more poverty, more and more inequality, more and more violence, more and more subjection of our lives to money. Dignity is not a private matter, for it involves the recognition of the dignity of others: in a world based on the negation of dignity, this inevitably involves the struggle for radical change. It is precisely the pursuit of personal dignity that confronts us with the urgency of revolution."
