Human purposes are dwarfed by such a blank horizon.
When we see it from an island in a vast ocean we know we are resting in shelter. On the plains, the horizon is always with us and there is no retreating from it. Its blankness travels with our every step and waits for us at every point of the compass. Because we have very few reference points on the spare earth, we seem to creep over it, one tiny point of consciousness between the empty earth and the overreaching sky. Because of the flatness, contrasts are in a strange scale.
