“People,” Shai said, rising to fetch another seal, “by nature attempt to exercise power over what is around them. We build walls to shelter us from the wind, roofs to stop the rain. We tame the elements, bend nature to our wills. It makes us feel as if we’re in control.

“Except in doing so, we merely replace one influence with another. Instead of the wind affecting us, it is a wall. A man-made wall. The fingers of man’s influence are all about, touching everything. man-made rugs, man-made food. Every single thing in the city that we touch, see, feel, experience comes as the result of some person’s influence.

“We may feel in control, but we never truly are unless we understand people. Controlling our environment is no longer about blocking the wind, it’s about knowing why the serving lady was crying last night, or why a particular guard always loses at cards. Or why your employer hired you in the first place.”
