At the end of my tour, I would take a final look around, and I should have felt happy that everything was there. After all, it could just as well not have been. There could have been nothing but grass here—large clumps of wind-lashed steppe grass and the rosettes of thistles. That’s what it could have been like. Or there could have been nothing at all—a total void in outer space. But perhaps that would have been the best option for all concerned.
