"Death has no power the immortal soul to slay, That, when its present body turns to clay, Seeks a fresh home, and with unlessened might Inspires another frame with life and light." It was the keynote of Plato's philosophy. Plato says: "Soul is older than body. Souls are continually born over again into this life." The idea of Reincarnation was spread widely in Greece and Italy by Pythagoras, Empedocles, Plato, Virgil and Ovid. It was known to the Neo-Platonists, Plotinus and Proclus. Plotinus says: "The soul leaving the body becomes that power which it has most developed. Let us fly then from here below and rise to the intellectual world, that we may not fall into a purely sensible life by allowing ourselves to follow sensible images...." It was the fundamental principle of the religion of the Persian Magi. Alexander the Great accepted this idea after coming in contact with the Hindu philosophers. Julius Caesar found that the Gauls had some belief regarding the pre-existence of the human soul. The Druids of old Gaul believed that the souls of men transmigrate into those bodies whose habits and characters they most resemble. Celts and Britons were impressed with this idea. It was a favorite theme of the Arab philosophers and many Mahomedan Sufis. The Jews adopted it after the Babylonian captivity. Philo of Alexandria, who was a contemporary of Christ, preached amongst the Hebrews the Platonic idea of the pre-existence and rebirth of human souls. Philo says: "The company of disembodied souls is distributed in various orders. The law of some of them is to enter mortal bodies, and after certain prescribed periods be again set free." John the Baptist was according to the Jews a second Elijah; Jesus was believed by many to be the re-appearance of some other prophet. (See Matt, xvi, 14, also xvii, 12.) Solomon says in his Book of Wisdom: "I was a child of good nature and a good soul came to me, or rather because I was good I came into an undefiled body."
