Dr Chaudhury is concerned to defend what is responsible and hopeful in contemporary ecological thinking, but to avoid the trap of denying that any positive contribution can be made by western science and technology. Critical rationalists do not need to agree with her suggestions and recommendations in order to welcome her positioning of environmental issues alongside the traditional human and political debates about freedom. The Indian perspective that informs this book is particularly impressive and interesting. David Miller (University of Warwick) Professor Mahasweta Chaudhury is Professor for Philosophy at Calcutta University in India. In the late sixties she studied at the London School of Economics under Karl Popper, John Watkins, Alan Musgrave and Imre Lakatos.
