> If in the far far future we develop a means of resurrecting the dead, the epitaphs on tombstones may be used to determine who deserves resurrection. But of course this is extremely fanciful speculation.

That's unlikely unless the dead person is exceptionally well-preserved (or you're just creating Generic Human Body #42 and giving it the dead person's name). Brain structure doesn't really survive current burial/embalming techniques and I imagine that any sort of "immortal soul" may have long left by then. Cryonics aims for this sort of far-future resurrection, but even it has problems about viability.
