'This is a timely book, with penetrating discussion of issues very much in the forefront of the contemporary philosophy. Despite the prominence of negative arguments it contains much to contribute positively to our understanding of what is needed for a conception of rationality and objectivity that covers ethics and value theory generally as well as physics.'
