Acknowledgments

Everyone we meet is a teacher. For their teachings, I thank everyone I’ve met.

In this post-Covid time, for this post-Covid title, I especially thank Beatriz González Martín, for her love and her patience. Besitos.

I also thank Vadim Gershteyn, who edited the book and challenged (and thereby helped to improve) some of its theses, as well as Yaroslav Kiyenko, who reviewed the book from a legal perspective. Thank you.
