Abstract

On the face of it, the idea of divine action in nature brings challenges to the autonomy of nature, and thus to the foundation of the natural sciences. According to the contemporary scientific world view, nature does not need anything extra to bring about any event which happens in nature. Apparently contrasting with this view, the main monotheistic religions claim that God is capable of intervening in the universe to guide it to its end and completion, and does so. This dilemma has brought theologians to search for a way in which God could perform this activity without interfering with the natural processes. The indeterminism of quantum events seems to be a conceptual framework which provides the place where God could choose the outcome of any event, given its indeterminacy. This solution, however, raises several difficulties for the traditional understanding of God as omnipotent, omniscient, provident, and transcendent. In the end, God has to act as another natural cause. The root of this dilemma (God’s action against nature’s actions) is the notion of deterministic causality used in the debate, which remains unexplained, and the assumption that God depends upon the natural order to act. This project is to evaluate some modern approaches to the problem of divine action, and to consider Aquinas’ views on causality, with which it is possible to hold a non-deterministic interpretation of nature. Then, to see first how he applies this notion to God’s causality, to show how nature depends on God, and second how God acts providentially in all natural operations, as a first cause moving a secondary cause.
