The principle claiming that nothing occurs without a cause expresses a universal human desire to give causes the role of an order generating factor that makes the world comprehensible and susceptible to explanation. Another epistemic consequence of that approach is the possibility to reconstruct past events and forecast the future by arranging successive facts in causal chains. There is also an ontological consequence. Causality entails the thesis of the necessity of the existence of a self-supporting being which exists entirely due to its own nature. In a different text the authoress tried to show that this being is identical with God.
