Amartya Sen delivered a distinguished public lecture to a packed Sheldonian Theatre this week. The lecture was chaired by the Chancellor, the Rt. Hon. Lord Patten of Barnes. Speaking about the subject of his book The Idea of Justice, Professor Sen explored the philosophical and historical concepts of justice, and in applying it to today’s global context challenged that ‘there are things to do’. Hilary Putnam has said: ‘I believe that Amartya Sen’s The Idea of Justice is the most important contribution to the subject since John Rawls’s A Theory of Justice appeared in 1971.’ The video podcast of the lecture will be released next Wednesday.
