“We have been looking at the natural world as something separate from humankind, using the common definition of nature as everything that is not us and is not made by us. It’s one useful way to see the world, but to gain a wider view, it is ultimately essential to bring our own species into the picture–just another living creature, after all, as miraculous as the rest. The question–which nature?–applies to human nature as well.”

— J.B. MacKinnon, The Once and Future World
