On Certainty, Proper Confidence, and Doubt: A Postfoundationalist and Critical Realist Epistemology for Doing Constructive Theology

Abstract

The present essay¹ seeks to focus on the meaning and challenges of doubt and lack of certainty in the context of doing academic theological work, whether in a Seminary setting such as my own, Fuller Theological Seminary, or in a “secular” university setting such as the University of Helsinki, my other institution. Throughout, I am raising questions such as whether any kind of certainty or confidence is available in the work of theology, particularly constructive theology, my own particular area of interest. Speaking of constructive theology, reflecting on the issues of doubt, certainty, and confidence is particularly important for the simple reason that it typically engages some non-theological disciplines such as natural sciences with their own criteria for truth. And in my case, dialogue with some other faith traditions, including Islam, further makes the issue of doubt pertinent. To make my inquiry manageable—and hopefully also dynamic—I am carrying critical conversation with two thinkers of the 20th century, namely the philosopher Ludwig Wittgenstein and the missionary bishop and cultural critic of the West, Lesslie Newbigin. Whereas the mature Wittgenstein was in search of certainty towards the end of his life, Newbigin sought for proper confidence. Both of them rejected the Cartesian indubitable certainty of modernity, on the one hand, and the dismissal of the possibility of truth in many streams of late modernity on the other. While critically affirming some key arguments of these two diverse thinkers, I also see the importance of buttressing their emerging epistemological programs with the help of insights from postfoundationalist and critical–realist epistemologies. It is clear without saying that this big task can only be outlined and sketched rather than scrutinized in any detail within a 1-h talk! My presentation is more an invitation to conversation and less any kind of finished project. I will first engage the two protagonists. Thereafter, before the summative and concluding reflections in terms of implications to theology and faith, a brief look at the meaning and nature of postfoundationalism and critical realism is attempted.
