Abstract
This chapter analyses how natural contingency refers both to the planning and the execution aspects of divine providence. For doing so, Silva contrasts the perspectives of some current trends within science and religion circles to find natural causal gaps in the created order to allow for God’s providence, with a typically Thomist approach within classical theistic circles. Silva suggests that classical theism offers a better understanding of the relation between natural contingency and divine providence than those who search for scientific spaces for God to guide creation towards its goals. In regards to the planning, Silva argues that God’s providence includes in its planning the achieving of the divine goals even by means of created, contingent in their action, natural things causing indeterministically. God’s goals include those contingent effects because they are ordered to new good things in creation. This is the Thomist idea to express that God, through not intended effects (be it contingent or even evil events), can bring about new good things to creation. In regards to the execution of that planning, Silva argues first that, contrary to some positions that see God acting in the a-causal indeterministic spaces provided by contemporary science, a causal understanding of indeterminism that distinguishes between causation and determinism, allows for truly contingent happenings within the created natural world. Then Silva shows how, by complementing these ideas with the doctrine of primary and secondary causation, at least as understood by Thomas Aquinas, one may offer an explanation of how God’s providence is involved in the whole of creation. Thus, even by means of created, indeterministic natural causes (that can be described as deficient instruments), God achieves his goals and intentions by causing them to cause indeterministically.
