Some thoughts from Vanhoozer about rationality

Creation is the first theo-dramatic word: let it be. Alvin Plantinga appeals to the doctrine of creation when he speaks of the “design plan” of the human mind. God has created human beings so that their cognitive faculties will yield true beliefs, given optimal conditions and proper functioning. Plantinga argues that we are warranted in holding a belief if it is the product of reliable belief-forming cognitive mechanisms… . [The Drama of Doctrine, 302]

It is because of epistemic corruption that we need to supplement reliabilism with fallibilism. Fallibilism insists that rationality, rather than being a matter of starting points, is actually a matter of one’s willingness to subject one’s beliefs to critical testing. [303]

Fallibilism is a procedure of rationality. Like tools, however, procedures are only as good as the persons using them, and fallibilism does not address the problem of disordered and disoriented human knowers. …

Rationality obliges us to submit our thinking to critical testing. To practice criticizability, however, knowers must become intellectually honest and evince epistemic humility. Honesty and humility are not methodological procedures but personal virtues. Hence the rational person must ultimately be a person of intellectual virtue. Where is virtue to be found? According to the canonical maps [the canon], virtue requires a renewing not only of the mind but of the whole being; it requires a work of transforming grace, a reorientation to truth. …

A willingness honestly to acknowledge our preferences and biases is one such truth-conducive habit; closed-mindedness, by contrast, is not. A belief is justified on this view when it is held by a person of intellectual virtue. What we could term the drama of knowledge has to do with the struggle in each of us between intellectual virtue and intellectual vice. In the final analysis, knowledge in the theo-dramatic perspective has less to do with becoming a scholar and more to do with becoming a saint. [303-304]
