This is a revised edition of the paperback, Essays on Contract which was published by OUP in 1988. With the addition of a further previously unpublished essay, this book can be seen as the most up-to-date and comprehensive account of Professor Atiyah's views on the law and theory of contract. The new essay `Freedom of Contract and the New Right' charts the latest shift in the development of contract law, this time back in the direction of Freedom of Contract. This shift, Professor Atiyah argues, can be traced directly to the growing strength of the `New Right' and its advocacy of political and economic freedom.
