This chapter will proceed from, rather than argue towards, agnostic convictions. It will outline those convictions, characterizing agnosticism as the rational position. Given this, what attitudes and practices may we rationally adopt? This chapter will reject that indifference necessarily follows from agnosticism. This chapter will also argue that agnosticism, as it has been characterized, is not rationally consistent with sustained religious belief. We have another option, whose source we can find in religious ambivalence (as opposed to indifference). Agnosticism finds the case for God’s existence unconvincing, but remains unconvinced of God’s non-existence. The latter suggests openness towards religious views and even experiences. Citing precedent in metaphor, history, and everyday epistemological attitudes, this chapter will show how one can refrain from accepting a belief in general while entertaining it in particular instances, discuss the constraints of such ambivalence, and justify as rational certain forms of religious attitude and practice.
