The editors would like to thank the Fondazione Giorgio Cini for co-organising the conference held in 2019 at Isola di San Giorgio Maggiore (Venice), at which contributors to this book presented and discussed drafts of many of its chapters. The editors also express their gratitude to the Université de Sherbrooke (Chaire de recherche Droit, religion et laïcité; Centre de recherche Société, Droit et religion – SoDRUS), the Université de Montréal (Project PLURADICAL/FRQSC), CRIDAQ (Centre de recherche interdisciplinaire sur la diversité et la démocratie) and GSRL (Groupe Sociétés, Religions, Laïcités, CNRS-EPHE-PSL), which enabled the publication of this book. Particular thanks are due to Ann Pattison and Thomas Windisch, who devoted considerable time and effort to the linguistic review and editorial work.
