Objective Morality Without God?
A Friendly Debate Between an Atheist and a Christian
Co-authored with Tom Jump.
Tom and I both believe in objective morality—the idea that moral values are more than simply human inventions. But we disagree about where those values come from. Tom argues that morality is grounded in nature; I argue that it is grounded in God.
So which provides the better explanation for objective morality: nature or God? That’s the friendly debate explored throughout this book.
