Man's ultimate concern must be expressed symbolically, because symbolic language alone is able to express the ultimate.
Paul TillichWhy does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.
Paul Tillich[A] process was going on in which people were transformed into things, into pieces of reality which pure science can calculate and technical science can control. โฆ [T]he safety which is guaranteed by well-functioning mechanisms for the technical control of nature, by the refined psychological control of the person, by the rapidly increasing organizational control of society โ this safety is bought at a high price: man, for whom all this was invented as a means, becomes a means himself in the service of means.
