This distinction is echoed by some modern open theists, e.g. Gregory A. Boyd, who writes, "Divine goodness does not completely control or in any sense will evil." Aquinas partly explained this in terms of primary and secondary causality, whereby God is the primary (or transcendent) cause of the world, but not the secondary (or immanent) cause of everything that occurs in it. Such accounts explain the presence of natural evil through the story of the Fall of man, which affected not only human beings, but nature as well (Genesis 3:16–19). Especially since the Reformation the distinction between God's will and God's permission, and between primary and secondary causality, has been disputed, notably by John Calvin. Among modern inheritors of this tradition, Mark R. Talbot ascribes evil to God: “God’s foreordination is the ultimate reason why everything comes about, including the existence of all evil persons and things and the occurrence of any evil acts or events.” Such models of God's complete foreordination and direct willing of everything that happens lead to the doctrines of double predestination and limited atonement. Natural versus moral evil Jean Jacques Rousseau responded to Voltaire's criticism of the optimists by pointing out that the value judgement required in order to declare the 1755 Lisbon earthquake a natural evil ignored the fact that the human endeavour of the construction and organization of the city of Lisbon was also to blame for the horrors recounted as they had contributed to the level of suffering. It was, after all, the collapsing buildings, the fires, and the close human confinement that led to much of the death. The question of whether natural disasters such as hurricanes might be natural or moral evil is complicated by new understandings of the effects, such as global warming, of our collective actions on events that were previously considered to be out of our control. Nonetheless, even before the beginning of the Industrial Revolution (which many believe was the beginning point of global warming), natural disasters (e.g., earthquakes, volcanoes, tsunamis, flooding, fires, disease, etc.) occurred regularly, and cannot be ascribed to the actions of humans. However, human actions exacerbate the evil effects of natural disasters. The World Wide Fund for Nature (WWF) says human activity is a key factor that turns “extreme weather events into greater natural disasters.” For example, “deforestation and floodplain development” by humans turn high rainfall into “devastating floods and mudslides."
