The post-secular event within which we live is occasioned as the limit of the secular project. The secular project meets its limit in attempting to separate a religious private sphere from a public sphere while at the same time repeating as a demand a religious subjectivation of the public sphere: demanding conformity to a simple subjectivity, producing a world of simple subjects through a theologically determined metaphysics of conversion. In this latter demand secularism enforces a simplicity of its subjects and its world. Yet this simplicity cannot be taken up into or as life. To genuinely live and think the post-secular requires, then, not simply a resistance to the secular but a resistance to simplicity, developing ways of becoming otherwise than simply and of producing a world other than that which conforms to a metaphysics of conversion.This dissertation proposes to meet the requirements of the post-secular event by developing a post-secular political ontology drawn from the work of Judith Butler and Alfred North Whitehead. Read through and out of these two philosophers of becoming is a post-secular political ontology that is embedded within a metaphysics of creativity, a metaphysic that is itself already infected by the political. At the intersection of the work of Butler and Whitehead a metaphysic arises that is a systematic discourse of the political.From this metaphysic a political ontology is developed. This political ontology begins with a suspicion of grammar as a suspicion of a subject-predicate form of thought that grounds ontologies of substance. With this suspicion, being is allowed to unfold as its becoming, particularly as a becoming material, so that actuality is a becoming materiality. This is also a relational becoming of feeling, becoming as a process of intensive feeling that can never be finalized for itself, always suffering its own continual downfall. Finally, but without finality, actuality is a becoming of creativity, opened by a divine violence that ruptures history by the possible, leading to a post-secular political ontology of the future.v "These practices of instituting new modes of reality take place in part through the scene of embodiment, where the body is not understood as a static and accomplished fact, but as an aging process, a mode of becoming that, in becoming otherwise, exceeds the norm, reworks the norm, and makes us see how realities to which we thought we were confined are not written in stone
