Question

For dualists (like me), it’s fairly easy to think that there is life after death, even without any traditions about it (which don’t really exist).
A well-known topic — but what about life before birth? Is there any reasoning for distinguishing between life before birth and life after death?
Out of the four possible positions, I’ve only encountered three: no before and no after; yes before and yes after; no before and yes after. But I’ve never come across the fourth position — yes before and no after — and to me it actually sounds more plausible than the option of no before and yes after. Because the spontaneous creation of a soul seems to me a bit harder to accept than the dissipation of a soul when the vessels break.
