The religious person enjoys a great advantage when it comes to answering the crucial question that hangs over our time like a threat: he has a clear idea of the way his subjective existence is grounded in his relation to “God”. I put the word “God” in quotes in order to indicate that we are dealing with an anthropomorphic idea whose dynamism and symbolism are filtered through the medium of the unconscious psyche. Anyone who wants to can at least draw near to the source of such experiences, no matter whether he believes in God or not. Without this approach it is only in rare cases that we witness those miraculous conversions of which Paul’s Damascus experience is the prototype. That religious experiences exist no longer needs proof. But it will always remain doubtful whether what metaphysics and theology call God and the gods is the real ground of these experiences. The question is idle, actually, and answers itself by reason of the subjectively overwhelming numinosity of the experience. Anyone who has had it is seized by it and therefore not in a position to indulge in fruitless metaphysical or epistemological speculations. Absolute certainty brings its own evidence and has no need of anthropomorphic proofs.
