Today, I read about the great Greek philosopher and mathematician Pythagoras (c. 570-495 BC) who believed in reincarnation... and he wasn't even a Buddhist. He said, "All things change, nothing perishes. As a wax is stamped with certain figures, then melted, then stamped anew with others, yet it is always the same wax. So, the soul being always the same yet wears at different times different forms." http://www.bartleby.com/181/341.html
It was this belief that made Pythagoras a vegetarian and it was a philosophy he advocated to his many students.
It made me think that perhaps if people stop associating reincarnation with Buddhism and dismissing it because of that association but instead, look at reincarnation on its own merits, they would be more open to the concept. Buddha did not invent reincarnation, he merely explained his observation of it. We may not be able to prove reincarnation scientifically at the moment but it does not mean that we will not be able to in the future. After all, if 200 years ago, you said that we would be able to fly 180,000 pounds of metal in the sky with hundreds of people in them, people would have called you mad.
Reincarnation is not a Buddhist concept but a universal one.
