Several years back, I learned to be wary of acknowledging any, let alone all, of those who had any contribution to my work. Not because I am ungrateful to them but because I am reticent to compile a list of people who might subsequently be accused of being guilty parties. Although I have been extremely grateful for a vast number of conversations I have had with people across multiple contexts during the research and writing of this book, I would like – above all – to thank sincerely my friends and family, especially my wife Kasia, my children Filip and Klara and my parents Maria and Hindemburgo. You have supported me throughout this journey, and because of you, everything has had a meaning.
