From an interview of CG Jung by Georg Gerster conducted on June 7, 1960, for broadcast on the Swiss radio network, as found in the book CG Jung speaking.
GG: “When I asked you earlier about a critique of our civilization I… was thinking of the problem of our time, as they say. There must have been periods when man’s relations with the unconscious through various other channels of communication were infinitely more alive than they are today.”
CGJ: “Yes, there is no doubt that it was only the 19th century that broke with this tradition and became increasingly intellectual, with the result that a lot of vitally necessary things have become obsolete. Just think of the crisis of Christianity we are passing through today — it simply means that we have lost all sense of its necessity. We no longer know what it is good for. In earlier times people knew, in a way. Naturally they had faith, but this faith was rooted in the feeling that the Christian tradition was `satisfactory,’ it was something self-evident, part of the picture. Even with scientific books, you need only think of old Scheuchzer, of Zürich who began his scientific works with the story of Creation!
