The Analytic Christian: A Positive Case for Objective Morality (Dr. Eric Sampson)

From The Analytic Christian:

There are two broad strategies one can use to show the truth of moral realism- defense and offense. When playing defense, one tries to show that criticisms of the view do not succeed, while criticisms of alternative positions do succeed. This could be called, "The Argument from Elimination." When playing offense, one tries to give positive reasons in favor of moral realism. In this interview, Dr. Eric Sampson will play offense by providing four arguments in support of moral realism.
