Franklin Merrell-Wolff continues his critique of Carl Jung’s identification of the intellect with the devil by calling attention to the meaning of ‘Lucifer’ as given in The Secret Doctrine. He begins by giving a brief sketch of the process of involution and evolution as presented in The Secret Doctrine, and summarizes the conception of man as consisting of seven principles. Wolff then proceeds to give a detailed description of the Theosophical conceptions of “Globes,” “Rounds,” and “Races.” He gives an account of the evolution of man to the point where the intellectual mind is added to the desire mind of the proto-human by the descent of more evolved ex-men or Manasaputra. Wolff suggests that a distinction may be made among four classes of human beings in the world today who are on various levels of intellectual development. Wolff then makes a case for correlating the myth of the fall of Lucifer with the descent of the Manasaputra, suggesting that Lucifer should not be interpreted as a principle of evil, but as a bringer of the light of intelligence to the evolving proto-human being. He emphasizes that the principle of the intellect brings a power for both good and evil, but that in itself it offers the greatest potential for the continuing evolution of man to become a coworker with the gods. He offers personal testimony as to the numinous value realized by the study of mathematics. He concludes this elaboration of the significance of Lucifer by calling attention to the myth of Prometheus, the bringer of the fire of the intellect, comparing both to the descent of the Manasaputra, which was a benign development for the proto-human humanity of this Earth, though a punishment for those who had to descend.
