There has to be a pressing reason to add to the mountain of material which has grown up around the work of Paul Tillich. Has not the ground been exhausted, the sponge wrung dry? While it would be presumptuous to claim that the present article deals with some hitherto unturned stone, our contention is that by asking a relatively simple question, a strange defect in Tillich's system becomes evident which seems to have been largely ignored. If this contention succeeds, then perhaps the presence of yet another article on Tillich may be justified.
