What is the foundation of Pagan ethics?

Pagans don’t have a holy book with commandments from a deity. We tend to derive our ethics from reasoning about the world around us. We cultivate virtues rather than following commandments.

But we also have a specifically and recognisably Pagan response to the world.

Teo Bishop writes, “I have always believed that the stories you tell about the gods you worship need to be relevant in the world you live in. They must be more than just stories. They must have application.” He goes on to say that “the intersection of the myth and the meaning is where morality is born”.
