Isaac Newton's Occult Studies - Writings

Writings

Due to the threat of punishment and the potential scrutiny he feared from his peers within the scientific community, Newton may have deliberately left his work on alchemical subjects unpublished. Newton was well known as being highly sensitive to criticism, such as the numerous instances when he was criticized by Robert Hooke, and his admitted reluctance to publish any substantial information regarding calculus before 1693. A perfectionist by nature, Newton also refrained from publication of material that he felt was incomplete, as evident from a 38-year gap from Newton's alleged conception of calculus in 1666 and its final full publication in 1704, which would ultimately lead to the infamous Leibniz–Newton calculus controversy. In 1936, a collection of Isaac Newton's unpublished works were auctioned by Sotheby's on behalf of Gerard Wallop, 9th Earl of Portsmouth, who had inherited them from Newton's great-niece. Known as the "Portsmouth Papers", this material consisted of three hundred and twenty-nine lots of Newton's manuscripts, over a third of which were filled with content that appeared to be alchemical in nature. At the time of Newton's death this material was considered "unfit to publish" by Newton's estate, and consequently fell into obscurity until their somewhat sensational reemergence in 1936.

At the auction many of these documents were purchased by economist John Maynard Keynes, who throughout his life collected many of Newton's alchemical writings. Much of the Keynes collection later passed to eccentric document collector Abraham Yahuda, who was himself a vigorous collector of Isaac Newton's original manuscripts.

Many of the documents collected by Keynes and Yahuda are now in the Jewish National and University Library in Jerusalem. In recent years, several projects have begun to gather, catalogue, and transcribe the fragmented collection of Newton's work on alchemical subjects and make them freely available for on-line access. Two of these are The Chymistry of Isaac Newton Project supported by the U.S. National Science Foundation, and The Newton Project supported by the U.K. Arts and Humanities Research Board. In addition, The Jewish National and University Library has published a number of high-quality scanned images of various Newton documents.
