I. The Mission of Spiritual Science

Knowledge of this fact was never quite lost, even in the time when men had ceased to believe that super-sensible faculties within the soul could be developed so as to give access to the super-sensible. One particular thinker reduced this faculty to its smallest limit: it was impossible, he said, for men to penetrate by super-sensible vision into a world that comes objectively before us as a spiritual world, just as animals, plants and minerals and other people are encountered in the physical world. Yet even he had to recognise impartially that something super-sensible does exist and cannot be denied.
