I have zero background in philosophy, so forgive me for...asking this in an informal manner.
We have a hypothetical scenario. Suppose that our consciousness at some time were reducible to electrobiological material in our body, including nerves and nerve connections in our brain, other brain cells and the exact state of electrical movement. A conscious state would include memories, emotions, sensory perception, and constitutes the total conscious "experience" of the subject.
Assume that our technology is sufficiently advanced to both (a) understand the exact representation of a conscious state as electrobiological material, and (b) decompose electrobiological material, and recompose the decomposed electrobiological material into its previous configuration.
If this hypothetical scenario were possible, and a conscious subject's body (including electrobiological material) were shattered into a million pieces, the subject would clearly die. However, if we were to combine this pieces and "recreate" the original configuration, including all nerve connections, wouldn't the conscious state of this subject be revived, including all memories and emotions?
