I'm struck by how very few people outside a rarefied world of true believers understand what you mean when you say human rights - that includes development experts and economists who are very keen to implement the UN Millennium Development Goals. They've told me quite frankly, that they don't know exactly what a human rights approach is.

The governments are seen to be less effective than they used to be. The private sector is perceived as being so much more efficient, and so globalization implies a transfer of power to the private sector.

We must understand the role of human rights as empowering of individuals and communities. By protecting these rights, we can help prevent the many conflicts based on poverty, discrimination and exclusion (social, economic and political) that continue to plague humanity and destroy decades of development efforts. The vicious circle of human rights violations that lead to conflicts-which in turn lead to more violations-must be broken. I believe we can break it only by ensuring respect for all human rights.

It is a great problem for the true international agenda of human rights that the United States, uniquely among industrialised countries, has not ratified three main instruments, has not ratified the Covenant on Economic, Social and Cultural Rights, or the Convention on the Rights of the Child, or the Convention for the Elimination of Discrimination Against Women, and we could have so much richer a debate and dialogue on international human rights standards if the superpower would sign up to the agenda.

Democracy is about constant vigilance. It's not straightforward, there will always be setbacks and you get particular be it religious fundamentalists, Christian fundamentalism - a partly conservative approach and actually trying to put women in a more traditional role. And we have to resist that.

Climate change is the greatest threat to human rights in the 21st century.

Symbols give us our identity, our self image, our way of explaining ourselves to ourselves and to others. Symbols in turn determine the kinds of stories we tell, and the stories we tell determine the kind of history we make and remake.
