 Seneca further agrees with earlier Stoic physics in taking divination seriously. In his discussions of thunder and lightning in the Natural Questions, Seneca explains that, while every natural event is a sign, we should not think of God busying himself with sending us, as it were, a sign at every particular occasion. Rather, we should explain natural events by seeking out their natural causes, and at the same time understand that the order of things as a whole is established by God. Since there is this order, divination is possible (NQ 2.32.1–4). Fate is the necessity of all events and actions, which no power can disrupt (2.36). Prayer cannot change fate; but since the gods have left some things unresolved, prayer can be effective (2.37.2).
