I'll offer another reason. Unfortunately, I couldn't find a suitable online resource, so I'll refer to a similar reasoning proposed for the existence of God. So, to rephrase an argument provided at SEP (see Arguments IX and X for the original form):kmath wrote:2. If you believe in rebirth for a reason not listed above, what is the reason?
It would be demoralizing not to believe there is a moral order to the universe.
Demoralization is morally undesirable.
There is a moral advantage in believing that there is a moral order in the universe.
The doctrine of karma and rebirth provides the best theory of the workings of moral order.
Therefore there is a moral advantage in accepting the doctrine of karma and rebirth.
Morality demands that we ought to aspire to become as good as we can be.
If there is no source of moral order in the world, then the project of becoming as good as we can be is fraught with difficulties.
These difficulties would be taken away if we were assured of the truth of the doctrine of karma and rebirth.
Therefore we have a moral reason for getting ourselves in a state whereby we can come to believe in the truth of the doctrine of karma and rebirth.
