" Gripped by a feverish urge to climb, he felt like running up the stone stairs. People often talk of the attraction of the abyss. There is also the abyss above. Borluut was still going up; he would have liked to keep on going up for ever, melancholy at the thought that the stairway was doubtless going to stop and that at the end, on the edge of the air, he would still yearn to continue, go farther, higher. "
