If you think a person can be reanimated from their writings, even a tiny piece of carefully preserved neural tissue should be extremely valuable for making sure

If you think a person can be reanimated from their writings, even a tiny piece of carefully preserved neural tissue should be extremely valuable for making sure the person is simulated accurately. You should probably stop using the terms "dead" and "frozen" in this context. Cryopreservation seeks to avoid ice crystal formation, and cryonics seeks to avoid death. So it has the effect of affirming the consequent.
