We have quietly performed one of the strangest tricks in the history of belief. We let go of the old story that a creator set us above all living things and handed us the world to use—and then we kept the world anyway. We dropped the doctrine and pocketed the privilege. We still breed, train, cage, eat, and rearrange the lives of other creatures as though a permission slip from heaven were tucked in our back pocket, even after we have announced, loudly, that we no longer believe in the one who signed it.
This book begins in that contradiction and follows it everywhere it leads. If we are animals among animals, then we have no natural throne from which to rule the rest of life. And if, by some lingering conviction, we really are higher beings, then height was never a license to dominate—it was a summons to take responsibility. From the atheist's side and the believer's side, the same conclusion comes walking toward us: power is not proof of superiority. Power is an obligation.
