Leibniz argued that God would not create a world unless it was the best possible world. I defend Leibniz’s argument. I then consider whether God could refrain from creating if there were no best possible world. I argue that God, on pain of contradiction, could not refrain from creating in such a situation. I conclude that either this is the best possible world or God is not our creator.

In response to arguments against the existence of God, and in response to perceived conflicts between divine attributes, theists often face pressure to give up some pretheoretically attractive thesis about the divine attributes. One wonders: when does this unacceptably water down our concept of God, and when is it, as van Inwagen says, ‘permissible tinkering’ with the concept of God? A natural and widely deployed answer is that it is permissible tinkering iff it is does not violate the claim that (...) God is the greatest possible being. Call this the ’perfect being defense.’ In this paper I lay out some influential uses of the perfect being defense, and then argue that this strategy for defending theism fails. (shrink)

God is traditionally understood to be a perfect being who is the creator and sustainer of all that is. God's creative and sustaining activity is often thought to involve choosing a possible world for actualization. It is generally said that either there is (a) exactly one best of all possible worlds, or there are (b) infinitely many increasingly better worlds, or else there are (c) infinitely many unsurpassable worlds within God's power to actualize. On each view, critics have offered arguments (...) for atheism that turn on God's choice of a world. In what follows, I first discuss some background issues, and I then survey the contemporary literature on these arguments. (shrink)

This thesis explores possibilities that arise from regarding theodicy as the activity of descriptive understanding of Christian belief and practice as found in the classical theistic framework. First, any theodicy as an activity is analysed in terms of the role of philosophy, the place of epistemology, the basis of theology, and the taking of an apologetic stance. It is then argued that traditional approaches to theodicy suffer from methodological weaknesses which derive from formulating theodicy in terms of unbelief, and from (...) strictly theoretical analysis. The superiority of philosophical description is argued as better suited to understanding religious belief as held in the community of believers, with especial reference to relationships that hold between language and reality. A critical exploration follows of the approach to theodicy of a proponent of philosophical description, D.Z. Phillips, and consideration is given to the status of evaluations made by believers. In the light of this critique, two attempts are made to describe the shape of Christian theodicy using the interperson model of theological language. The first attempt, based on a description of actual interpersonal relationships, is found eventually to be open to serious objections. A second attempt is then made, based not only on interpersonal language, but using a distinction between "surface" and "depth" in religious language, and by arguing for the presence of an epistemological "direction" in religious belief. On this basis, a Theodicy of Dependence is developed as best describing the shape of Christian belief held in a world which is frequently hostile. (shrink)

Many have argued that if God exists then he must necessarily create the best possible world , which entails that the bpw necessarily exists, and is therefore the only possible world. But without any scope for comparison, the superlative term ‘best’ is clearly inappropriate and so the bpw cannot be the bpw at all! As such, it must be impossible for God to create it. Hence if God exists then he must of necessity make something that is impossible to create! (...) Because of its conclusion, I call this the repugnant argument. I consider a number of possible responses to this argument. (shrink)
