 According to the theory of radical determinism, any action we take only appears to be the result of our choosing that particular action over others. In truth, however, our choice is the outcome of various predetermined factors that cause it to happen in a certain time and place. Unlike radical determinists, the non-radical determinists, such as Polqar rejected the view according to which man’s actions are determined and only appear to be the result of one’s free choice. The non-radical determinists admit that there is a connection between the upper-lunar world and the sublunary world, however this connection is restricted merely to natural events; for example, an occurrence of an eclipse is determined and therefore can be known and predicted, unlike man’s decision to act in a certain way. For Abner, determinism is entailed by God’s omniscience, His absolute knowledge of past, present, and future. Any affirmation of one’s liberty in making decisions and choosing specific actions is incompatible with this idea of God’s perfect knowledge. In sum, for Abner, ascribing free will to human beings denies God’s omniscience. In opposition to Abner, Polqar attempts to reconcile the idea of man’s ability to choose with the concept of God’s perfect knowledge. Polqar rejects Abner’s view and contends that allowing man’s free will alongside God’s omniscience is the only way to defend God’s perfection.
