This book looks at the role of the imagination in science, from both philosophical and psychological perspectives. These contributions combine to provide a comprehensive and exciting picture of this under-explored subject. This collection of thirteen new essays reflects growing agreement that imagination plays a key role in science, not just in thinking up hypotheses, but in testing them.... The sixteen authors include many of those who have already made significant contributions to meeting the challenge. The volume furthers the debate and will encourage others to get involved. It is greatly to be welcomed... anyone interested in the scientific imagination will have a lot to learn from this volume.
