One of the goals of Apologetics is to deal with the objections that people have regarding the existence of God. For the last several weeks, we have been listing some of these objections and the arguments that address them. Here is where we address the objection based on arbitrary models:
Arbitrary Models. This objection states that it is only because we have modeled reality as contingent or composed of actuality and potentiality that we are, therefore, forced to conclude that there is a Necessary Being or Pure Actuality. This, they insist, is an arbitrary and loaded way to view reality.
Theists point out that the contingency/necessity model is not arbitrary but is logically exhaustive. Either there is only a Necessary Being, or else there is a contingent being(s) as well as a Necessary Being. But there cannot be merely a contingent being(s). For contingent beings do not account for their own existence, since they are but might not be.
Likewise, either everything is one undifferentiated Pure Actuality or pure potentiality or a combination of actuality and potentiality. No other possibility exists. But there cannot be two Pure Actualities, since actuality as such is unlimited and unique. There cannot be two ultimates or two infinite beings. So whatever else exists must be a combination of actuality and potentiality. But since no potentiality can actualize itself, then beings composed of actuality and potentiality must be actualized by Pure Actuality.
