An Essay towards a Real Character, and a Philosophical Language

An Essay towards a Real Character, and a Philosophical Language (London, 1668) is the best-remembered of the numerous works of John Wilkins, in which he expounds a new universal language, meant primarily to facilitate international communication among scholars, but envisioned for use by diplomats, travelers, and merchants as well.

Emanuel Swedenborg

Emanuel Swedenborg ((born Emanuel Swedberg; 29 January 1688 – 29 March 1772) was a Swedish Lutheran theologian, scientist, philosopher, revelator and mystic who inspired Swedenborgianism. He is best known for his book on the afterlife, Heaven and Hell (1758). Swedenborg had a prolific career as an inventor and scientist. In 1741, at 53, he entered into a spiritual phase in which he began to experience dreams and visions, beginning on Easter Weekend, on 6 April 1744. It culminated in a 'spiritual awakening' in which he received a revelation that he was appointed by the Lord Jesus Christ to write The Heavenly Doctrine to reform Christianity. According to The Heavenly Doctrine, the Lord had opened Swedenborg's spiritual eyes so that from then on, he could freely visit heaven and hell and talk with angels, demons and other spirits and the Last Judgment had already occurred the year before, in 1757. For the last 28 years of his life, Swedenborg wrote 18 published theological works—and several more that were unpublished. He termed himself a "Servant of the Lord Jesus Christ" in True Christian Religion, which he published himself. Some followers of The Heavenly Doctrine believe that of his theological works, only those that were published by Swedenborg himself are fully divinely inspired.
