The printed version may be different intentionally blank page Acknowledgments The book has taken its shape over years and experiences, during which I have built up a remarkable debt of gratitude. I owe much to my students: thank you for all your challenges. Thanks to the guests of the doctoral Summer School ReSPoS and the MeMa seminars in Milan for the many fruitful discussions on causation. Thanks to the participants to the Chess seminars in Durham, the APSA section on Mixed Methods, the PSA Method Conference, and the ecpr joint session of workshops for their comments on previous attempts to get to the point. Thanks to the Compasss community and, among them, to Airo Hino and Adrian Duşa for their kind support in the inevitable moments of bewilderment. Special thanks to Carsten Schneider, Benoit Rihoux, and Charles Ragin for their generous teaching that, long ago, initiated this all. I gratefully acknowledge the financial support of the European Grant ERC-ADG-2015 694632. The usual disclaimer applies.
