After the consideration of Marcel's appraisal of the traditional proofs for the existence of God one might be tempted to ask whether he has not effectively re-closed the door which was opened for discussion. If the God whose existence is demonstrable is so small a concern of his, what possibility is there for a fruitful dialogue between a traditional metaphysician and this philosopher of existence. If it is possible at all, the dialogue cannot arise from the acceptance of the proofs, even though in various places Marcel speaks of the logical validity of the proofs. In fact, if one considers the current re-investigation of the proofs on the part of a number of philosophers, Marcel's acceptance of their validity often appears by comparison annoyingly uncritical.
