 By contrast, other authors see stochasticity as a genuine design feature, and not just as a physicalist gloss. Their challenge is to explain how divine providence is compatible with genuine randomness. (Under a deistic view, one could simply say that God started the universe up and did not interfere with how it went, but that option is not open to the theist, and most authors in the field of science and religion are not deists.) The neo-Thomist Elizabeth Johnson (1996) argues that divine providence and true randomness are compatible: God gives creatures true causal powers, thus making creation more excellent than if they lacked such powers. Random occurrences are also secondary causes. Chance is a form of divine creativity that creates novelty, variety, and freedom. One implication of this view is that God may be a risk taker—although, if God has a providential plan for possible outcomes, there is unpredictability but not risk. Johnson uses metaphors of risk taking that, on the whole, leave the creator in a position of control. Creation, then, is akin to jazz improvisation. Why would God take risks? There are several solutions to this question. The free will theodicy says that a creation that exhibits stochasticity can be truly free and autonomous:
