Moral disagreement is commonly regarded as a threat to objective morality in scholarly circles and in popular culture--perhaps being one of the most significant objections against Christian theistic moral theory. Some skeptics argue that as people divide about what is right and wrong--often inciting moral evil and causing human suffering--the Christian view of an all-powerful, all-knowing, and all-good God behind morality is inconsistent. Accordingly, I'm Right/You're Wrong investigates whether moral disagreement abolishes the traditional Christian view of God and its accepted ontology of morality. It further analyzes and proposes the logical problem of moral disagreement, applying the methodology proposed by Christian philosopher Alvin Plantinga in his free-will defense. Moreover, this book discusses key theological and philosophical perspectives regarding God's omniscience, creational power, and the human attribute of free will.
