a world in which omnipotence exists than a world in which omnipotence does not exist. The dilemma of omnipotence is similar to another classic paradox—the irresistible force paradox: "What would happen if an irresistible force were to meet an immovable object?" One response to this paradox is to disallow its formulation, by saying that if a force is irresistible, then by definition there is no immovable object; or conversely, if an immovable object exists, then by definition no force can be irresistible. Another response to this that the only way out of this paradox is if the irresistible force and immovable object never meet. However this does not hold up under scrutiny, because an object cannot in principle be immovable if a force exists that can in principle move it, regardless of whether the force and the object actually meet. Types of omnipotence Augustine of Hippo in his City of God writes "God is called omnipotent on account of His doing what He wills" and thus proposes the definition that "Y is omnipotent" means "If Y wishes to do X then Y can and does do X". The notion of omnipotence can also be applied to an entity in different ways. An essentially omnipotent being is an entity that is necessarily omnipotent. In contrast, an accidentally omnipotent being is an entity that can be omnipotent for a temporary period of time, and then becomes non-omnipotent. The omnipotence paradox can be applied to each type of being differently. In addition, some philosophers have considered the assumption that a being is either omnipotent or non-omnipotent to be a false dilemma, as it neglects the possibility of varying degrees of omnipotence. Some modern approaches to the problem have involved semantic debates over whether language—and therefore philosophy—can meaningfully address the concept of omnipotence itself. Proposed answers Omnipotence does not mean breaking the laws of logic A common response from Christian philosophers, such as Norman Geisler or William Lane Craig, is that the paradox assumes a wrong definition of omnipotence. Omnipotence, they say, does not mean that God can do anything at all but, rather, that he can do anything that is possible according to his nature. The distinction is important. God cannot perform logical absurdities; he cannot, for instance, make 1+1=3. Likewise, God cannot make a being greater than himself because he is, by definition, the greatest possible being. God is limited in his
