We again see people cutting each other's throats to support childish theories of how to produce paradise on earth. It is not very difficult to see that the powers of the underworld - not to say of hell - which were formerly more or less successfully chained and made serviceable in a gigantic mental edifice, are now creating, or trying to create, a State slavery and a State prison devoid of any mental or spiritual charm.

Karl Jung, Psychology and Religion, Yale University Press, 1938.
