Henry More (1614-1687), who published in 1642 a Platonical Song of the Soul, in four books, was six years younger than Milton. He lived a hermit-life at Cambridge, was a great admirer of Plato, a correspondent of Descartes, and a friend of Cudworth. He wrote various prose works, and in his Immortality of the Soul showed that he was a full believer in apparitions and various psychical phenomena. He fully sympathized with Glanvil in his belief there was a substantial basis of spiritual agency in witchcraft; and he believed that he himself had had superhuman communications. He seems to have adopted the Platonic notion of the soul's pre-existence.
