The key to Ratzinger's take on B. is B.'s take on reason as personified in Aristotle. B. is not against Aristotle and for Plato. He is saving reason by proclaiming that reason without the experience of faith as self-transcendence of the being of the believing subject is damaged reason. Reason must be mystical by the experience of the self going out of self. As such it is pre-conceptual and contemplative. Therefore, B. is not pro-platonic as against Aristotle. He opts for reason contemplating a self energized by self-transcendence.
