So it is only fair for the acknowledgments section to begin with a small exercise in logic. It goes like this. The narrative structure of acknowledg- ment sections in sociology theses at the Department of Sociology, Stockholm University, during the last 5 years, boils down to the following logic. Let D be a doctoral candidate on the verge of defending her thesis. The process of writing a thesis, just like any other social process, unfolds in a dy- namic social space, a field of interaction spanned by the candidate’s social properties and those of her contacts. Upon the time of acknowledgment writ- ing ta, and provided that the narrative structure is known to D, the need arises to choose a proper narrative instance, which implies the selection of people, actions and events within a reasonable period of time that are worthy of recog- nition. D proceeds consequently to probe her social space for information, where B(D;r;tA) is a social space neighborhood centered around her with ra- dius r. The social space neighborhood is further partitioned into classes, which induce a naming order typically in a priority scale N ={supervisor/s ! col- league/s ! friend/s ! family (peripheral) ! family (nuclear)}. The people in the neighborhood can be associated with a set of actions deemed worthy of being acknowledged A(pjD) on the basis of a certain cri- teria that are either universally accepted within the time period of writing, or derived from the latest theses using a suitable heuristic. The acknowledgment text can thus be written with the help of an algorithm of the form: for every o in N: u := random number for every p in B(D;r;tAjo): write "To " + p for every a in A(pjD): write "thanks for doing " + a + phr[u] where phr is a set of standard phrases presumably suited for the occasion, for instance: phr = f"I will never forget you.", "You are simply the best.", "I couldn’t have done it without you.", :::g. The random number is intended to add variation to an otherwise totally deterministic text. xvii So now we are ready to move on to the particular narrative instance of this thesis. When I— doctoral candidate H— look around in my social space neighborhood B(H;r;tA), I notice that throughout the years I have been priv- ileged in various ways. Today, after a somehow long journey, I believe my greatest privilege has been to be able to create, bound only by my own limita- tions, to allow myself to be engulfed by my own ghosts, and reinvent myself as I see fit. To waste as much time as I wanted and to explore new opportunities as I deemed necessary. This freedom is not naturally given, though; someone has to pay for it. So my first acknowledgments go to everyone who has contributed to financing my current social space state B(H;r;tA). Since I believe important things should be named first, I introduce a reverse naming order N˜ = flip(N) here (which also translates into exploring the social space neighborhood from the center and outwards, in the direction of increasing r, a procedure somehow more appealing, mathematically speaking). I would first like to thank my family: my father Luis Pedro, my mother Adriana Angela and my brother Mariano. You have always been relentlessly supportive of my projects, and in particular of my decision to start anew in Sweden. My mom should be especially commended for her strength and pa- tience, and not the least for suggesting that I should look for some social sci- ence application to my modeling interests. To both my parents: thanks for always putting me and my brother above everything else. You have taught us many important things, and have been wise and good-willed enough to do it in the only way fundamental things can be taught: by subtle, consistent, exem- plifying insinuation. A good example has to do with my relationship to books and reading. There was never a formal moment, not that I can remember any- how, where the importance of books was pointed out to me. But books have always been around at home: many topics in many rooms. And besides your bed, so that even after a hard day’s work a page or two should precede your decent into the dark unknown.
