While Westerners domesticated and eventually industrialized the animals we eat—and thus came to view them as dumb and inferior—Arctic cultures saw whale hunting as a match between equals.
The author uses humanity's domestication of the animals we eat, as a reason behind western ideas that animals are inferior to us. This shows that the idea that humans are above other animals depends heavily on the ideas that are passed down over the centuries. This means humanity only sees itself as the center of the animal world because of its habit of pushing subservience onto other species. This works to show a fundamental difference between indigenous and western ideals.
