Sociologist Laurie Taylor talks to one of the world's most eminent legal and political philosophers, Ronald Dworkin. Professor Dworkin discusses his concerns on the current state of democracy, liberty and human rights. What role does dignity play in politics? What are the core values that all citizens share? Dworkin is author of Is Democracy Possible Here? Principles for a New Political Debate (Princeton University Press). Adding their thoughts to the debate from the London School of Economics and Political Science are Francesca Klug, Professorial Research Fellow, Centre for the Study of Human Rights; and Julian Le Grand, Richard Titmuss Professor of Social Policy.
