The question whether reincarnation is real or not has caused great controversies and debates. It can be said without exaggeration that opinions differ greatly on this question, leading to heated discussions. On one side there are scientists who reject the question for lack of evidence. Some scientists even go so far to state that the idea of reincarnation is entirely unnecessary, because it is not possible to be measured and tested according to scientific procedure. On the other side we have mostly religiously minded people who accept the notion of reincarnation as part of their religious world view. But who is right?
