The role of choice in Gersonides’ theory of miracles, as presented in the Wars of the Lord, is discussed. The theory of miracles in Warsvi.2.10 is shown to be another link in his reconciliation of determinism with choice. After a brief review of his ideas about choice, his astral determinism is elucidated. The third part of the essay reviews his treatment of how miracles occur. Gersonides is shown to have established a “conditional miraculous determinism”; his concern for choice is the key to this solution.
