I realize that after decades of positive thinking the notion of realism, of things as they are, may seem a little quaint. ... When the stakes are high enough and the risks obvious, we still turn to people who can be counted on to understand those risks and prepare for worst-case scenarios.

Positive theology ratifies and completes a world without beauty, transcendence, or mercy.
