Bridgeport, Conn., acting as his magnetiser. The last of these lectures was delivered on January 25, 1847. The lectures were published in a book entitled, The Principles of Nature, Her Divine Revelations, and a Voice to Mankind. Davis continued to lecture, and to write voluminously. His written works consist of thirty-six volumes, nearly all of which, it is claimed, were produced while the author was in a state of clairvoyance. The chief of these are his first books, the Divine Revelations (1847), and The Great Harmonia (1850). In these Davis gives a history of the universe, the formation of the earth, the origin of man, and the gradual development of present civilisation. In his first volume he gives a "Key" to the principles of nature, and relates the "true" version of sacred history, correcting and explaining the Old and New Testaments as he goes along. He gives his interior impressions of the real scheme of the material universe and of the spiritual world, and the relations between the two.
Davis called this "revealed" system "The Harmonial Philosophy," and developed it at length in the six volumes of The Great Harmonia. In many points Davis's philosophy of life and his theory of disease resemble Quimby's, and much of the terminology is the same. (When Davis began to lecture and to write, Quimby had for several years been practising and teaching but, so far as known, Davis had never met Quimby.) For example, Davis states: "There is but one Principle, one united attribute of Goodness and Truth." This he calls the "unchangeable, eternal Positive Mind," which "fills all negative substances. Worlds, their forces, their physical existences, with their life and forces, are all negative to this Positive Mind.
