The claim that opinions are more trustable than knowledge is vividly present in small sectors of European society. The few sectors unified by a denial of science and its consequences become a crowd when they look to religious diversity: in the secular society, many prefer opinions shaped by narrow experience and unverified internet sources to scientific knowledge. This important book offers a remedy for this dangerous approach. The authors identify the fears and the foundational myths of issues, which can be managed only through fresh knowledge. * Alberto Melloni, Chief Scientific Advisor of the European Commission, Italy * An important international and interdisciplinary book which shows the diverse ways of measuring and supporting a religious culture among young people: those who will manage the issues of religious diversity and social integration in the future. * Louis-Leon Christians, Law and Religions Chair, Université catholique de Louvain, Belgium *
