Among the ancient Greeks, Socrates, Pythagoras, and Plato may be numbered among those who made reincarnation an integral part of their teachings. At the end of his life, Socrates said, "I am confident that there truly is such a thing as living again, and that the living spring from the dead." Pythagoras claimed he could remember his past lives, and Plato presented detailed accounts of reincarnation in his major works.
