"""This book is extremely impressive. It presents a new and original approach to the issue of the role of voluntariness in valid consent, one emerging from and informed by a thorough knowledge of the extensive literature in the field and in a wide array of different debates. The presentation is very well organized, and the overall strategy is powerfully and clearly articulated. At the same time, it contains a remarkable number of fruitful and suggestive arguments."" Roger Crisp, St Anne's College, University of Oxford, UK ""Kiener proposes a radical, novel account of when consent is voluntary, namely that consent is voluntary by default and only becomes involuntary when motivated by influences that cannot be interpersonally justified. His account has striking implications for organ donation, payment in clinical trials and nudging, and also extends to sexual relations. The most significant and original contribution to consent in the last 20 years."" Julian Savulescu, National University of Singapore"
