We'd learned a few things about the machine. First and foremost: what happens to your body and mind in any era stays with you—this thing didn't come with a refresh button, or infinite lives like in some video game. We'd come back with scars after Taylor was side speared in the Crusades, my little heathen. So naturally, we were cautious about a few things: like not wanting to bring back the bubonic plague. But such fears got us to thinking: what time was worth saving? Why were we the chosen people, like some Christian millenarians; how could we lose grasp of our prejudices, namely that we were special? Should the present—whatever that even is—be exactly as it is? Should we bump into someone or something ages ago and make everything different, would we be culpable? Would we feel guilty? All the world passed by us: presidents decreed genocides, and tyrants made us pay rent without our consent, and still we questioned our ethics.
So, we quelled any would-be lust for power by remaining mostly by ourselves—cinéma vérité anthropologists, taking it all in like framed landscape paintings in the academic departments of art museums. How wrong those moralists had it, how embarrassingly of their times! We made a game of it, actually: going to the museums after our excursions, and laughing at the historical record.
