Genuine philosophy has to begin with a felt experience of dependence on a transcendent source of power, together with a sense of astonishment at the lies and deception that rule the pre-philosophical state of being.   Philosophical reasoning will always be corrupt if it does not start with this experience (which must be renewed again and again), but, at the same time, this experience is ~only~ the starting point.  From there, reasoning is required (and then critique, and then speculative vision).
