Professor of Sociology and Director of the London School of Economics Ralf Dahrendorf gives his second Reith lecture from his series entitled 'The New Liberty'. In this lecture entitled 'The Liberal Option', Professor Dahrendorf explores the liberal options available to society. He questions why recognised problems in society, which also have visible solutions, do not make any great progress. Who is it that prevents this potential from being realised? To answer these questions he explores how social-economic structures affect our liberty.
