In The End of Captivity?, Tripp York addresses how we talk about the good of other animals in light of a stark impossibility: their freedom from us. While all of us in the animal (and plant) kingdom are interdependent upon one another, humans are unique in that we are the only animals who keep other animals captive. We keep animals in zoos, sanctuaries, circuses, conservatories, aquariums, research facilities, slaughterhouses, and on our farms and in our homes. York asks what such forms of captivity say about us, and how animal captivity shapes what we imagine to be the purpose of other animals. What does the fact that elephants, tigers, and horses perform in circuses say about how we see the world? What does the reality of zoological parks say about the people who create, support, decry, protest, and patronize them? How important is wildlife conservation for the good of the earth? What does “who” we put on our plate say about how we understand the theological role of other animals? These are just a few questions York tackles as he weaves through the convoluted politics surrounding the captive animals in our midst.
