This thesis was on how God is related to the truth-values of propositions on possible worlds - specifically, those propositions that do not seem to be about Him and constitute His ideas for what to create. It opened with a survey of some historical positions with special emphasis on Aquinas, Leibniz, Spinoza and Kant. Next, some criticisms were given for these so-called deity theories with the most space given to Brian Leftow’s critiques. The second chapter detailed Brian Leftow’s theological modality. (...) In it, secular modality is excogitated in an instant from eternity when God gets a set of creaturely natures in one imaginative act. His preferences that are based on His nature then determine the modality of what God thinks up. A number of objections were raised for the Leftowian project and the last chapter attempted to supplement an older deity theory with some insights from Leftow in order to avoid his initial criticisms.
