ABSTRACT
This chapter considers the Devil as well as the qualification of Voltaire's quotation and diagnoses whether Voltaire's claim "if God did not exist, then it would be necessary to invent Him" is true or not. Actually, God and the Devil go hand-in-hand in the Catholic Christian perspective from which Voltaire emerged. So, from Voltaire's perspective, it would be necessary to invent the Devil along with God, if both did not exist. God and the Devil, just like any spiritual being or realm, can act as useful fictions to help maintain order. So, in the end, it may be that it's necessary for certain people to invent the Devil, as an archetype of evil to be avoided at all costs. The divine command theory dilemma arises mostly when thinking about the kind of god believed to exist by Christians, Muslims, and Jews, namely, an all-powerful, all-knowing, all-good Supreme Being.
