Abstract
The goal of this paper is to facilitate ongoing dialogue between open and non-open theists. First, I try to make precise what open theism is by distinguishing the core commitments of the position from other secondary and optional commitments. The result is a characterization of ‘generic open theism’, the minimal set of commitments that any open theist, qua open theist, must affirm. Second, within the framework of generic open theism, I distinguish three important variants and discuss challenges distinctive to each. The significance of this approach is that it helps avoid conflating arguments bearing on specific versions of open theism with arguments pertaining to open theism simpliciter.
