There is no stimulant equal to expression. The more men write the more they know. Swedenborg continued to write, and following the "Principia" came "The Animal Kingdom," "The Economy of the Universe," and more vast reaches into the realm of fact and fancy. His books were published at his own expense, and the work was done under his own supervision at Antwerp, Amsterdam, Venice, Vienna, London and Paris. In all these cities he worked to get the benefit of their libraries and museums. Popularity was out of the question--only the learned attempted to follow his investigations, and these preferred to recommend his books rather than read them. And as for heresy, his disbelief in popular superstitions was so veiled in scientific formulas that it went unchallenged. Had he simplified truth for the masses his career would have been that of Erasmus. His safety lay in his unintelligibility. He was gracious, gentle, suave, with a calm self-confidence that routed every would-be antagonist. It was in his fifty-sixth year that the supreme change came over him. He was in London, in his room, when a great light came to him. He was prostrated as was Saint Paul on the road to Damascus; he lost consciousness, and was awakened by a reassuring voice. Christ came to him and talked with him face to face; he was told that he would be shown the inmost recesses of the Spirit World, and must write out the revelation for the benefit of humanity. There was no disturbance in the man's general health, although he continued to have visions, trances and curious dreams. He began to write--steadily, day by day the writings went on--but from this time experience was disregarded, and for him the material world slept; he dealt only with spiritual things, using the physical merely for analogy, and his geology and botany were those of the Old Testament. Returning to Stockholm he resigned his government office, broke his engagements with the University, repudiated all scientific studies, and devoted himself to his new mission--that is, writing out what the spirits dictated, and what he saw on his celestial journeys. That there are passages of great beauty and insight in his work, is very sure, and by discarding what one does not understand, and accepting what seems reasonable and right, a practical theology that serves and benefits can be built up. The value of Swedenborg lies largely in what you can read into him. The Swedish Protestant Church in London chose him as their bishop without advising with him. Gradually other scattering churches did the same, and after his death a well-defined cult, calling themselves Swedenborgians, arose and his works were ranked as holy writ and read in the churches, side by side with the Bible.
