What Money Can''t Buy is the Top Ten Sunday Times Bestseller from ''the superstar philosopher'', Michael Sandel

Should we financially reward children for good marks? Is it ethical to pay people to donate organs? What about hiring mercenaries to fight our wars, outsourcing inmates to for-profit prisons or selling citizenship?

In recent decades, market values have impinged on almost every aspect of life - medicine, education, government, law, even family life. We have drifted from having a market economy to being a market society. In What Money Can''t Buy Michael Sandel asks: Isn''t there something wrong with a world in which everything is for sale? And how do we protect the things that really matter?

''Brilliant, easily readable, beautifully delivered and often funny ... an indispensable book'' David Aaronovitch, The Times

''In a culture mesmerised by the market, Sandel''s is the indispensable voice of reason'' John Gray, New Statesman

''Provocative and intellectually suggestive ... little less than a wake-up call'' Rowan Williams, Prospect

''A star philosopher ... entertaining and provocative'' Diane Coyle, Independent

''Let''s hope that What Money Can''t Buy, by being so patient and accumulative in its argument and examples, marks a permanent shift in these debates'' John Lanchester, Guardian
