The Philosophy of Pythagoras

According to pythagoras, the soul can leave one body and go on to reside in other bodies. This is implied by reincarnation - but there's more here than just legend. In ancient philosophy, according to most pythagoreans, the soul and the body are utterly different sorts of thing. The soul is immaterial and probably indestructible. Body is material and will inevitably be destroyed. But this theory at least relates to a philosophical theory with a grand lineage, dualism.
