Dozois and Schmidt, eds. Roads Not Taken (1998)

     Gardner Dozois and Stanley Schmidt, eds. Roads Not Taken (1998) Tales of Alternate History, ranging from the mildly humorous to the ploddingly serious to the politically despairing. I omitted reading “The Forest of Time” (Flynn), a tale based on the many worlds interpretation of QT. The best stories use what’s known of the past, put a little twist on it, and extrapolate in terms of what we know or guess about social developments, such as “Outpost of Empire” by Silverberg (the Romans control Europe in the 1500-1600s); “We Could do Worse”by Benford (Joe McCarthy becomes president); “Aristotle and the Gun” by Sprague de Camp (in which a disgruntled scientist tries to nudge Aristotle into a more scientific direction, but fails; Aristotle decides to devote himself to ethics, political theory, and aesthetics instead.)
     The means of the twist range from sheer chance to time-travel. Chance is the most satisfying; we all know how much of our lives results from unforeseen and unforeseeable events. A taste for this kind of fiction is in itself specialised, and within it, there are subgenres of differing appeal. Inventing an alternate history in detail is a pleasant occupation, much like inventing a game universe, but one must have the same interests as the author to enjoy the result. Like a game universe, the setting has a feeling of arbitrariness about it. After all, change a few contingencies, and still another scenario is just as plausible. The characters who inhabit such alternative worlds differ from us only in accidentals, such as language, knowledge of the world, costume, political assumptions, and so on. But it’s these accidental details one must focus on, in order to give the alternate history a feel of plausibility, and in doing so, one tends to lose the essence of character. The writer of alternate history must find the right balance between accident and essence, and few succeed. Benford’s “We could do Worse” comes closest, perhaps because it’s the least different from our own world. * to **** (2002)
