Perhaps only careful readers are aware, but I belong to a denomination that doesn't believe in an afterlife in the Catholic sense. In line with Mykcob's previous OP, we believe death is death, until our physical bodies are resurrected.

This is an interesting position. Having no soul to lean on, there is no external continuity for our consciousness once we're dead.

Modern science is still trying to understand consciousness. With the emergence of AI, many even wonder if we could upload our consciousness into a computer, or download information into our brains. Can we replace neurons one by one with transistors? Would it still be us, or merely a copy?

If a resurrection is fundamentally impossible in regards to consciousness, what does that mean for sleep? Are we a different person when we wake up than when we fall asleep? What does the absence of consciousness during a coma mean for self-identity? Or when brain activity is essentially brought to zero, then brought back during generalized anesthesia, is there a discontinuity in consciousness?

Will medical resurrections one day be possible? Thoughts?
