Popularly stated, I would put it in this way: • When you assert that there is such a thing as evil, you must assume there is such a thing as good. • When you say there is such a thing as good, you must assume there is a moral law by which to distinguish between good and evil. There must be some standard by which to determine what is good and what is evil. • When you assume a moral law, you must posit a moral lawgiver—the source of the moral law. But this moral lawgiver is precisely who atheists are trying to disprove.
