Section 6 Department Chief Nakamura: Nonsense! There's no proof at all that you are a living, thinking life form.
Puppet Master: And can you offer me proof of your existence? How can you, when neither modern science nor philosophy can explain what life is?
Major Motoko Kusanagi: You talk about redefining my identity. I want a guarantee that I can still be myself.
Puppet Master: There isn't one. Why would you wish to? All things change in a dynamic environment. Your effort to remain what you are is what limits you.
Question: What exactly is a Ghost, and in the last line of the movie, what has occurred? Have the two merged into one and become a new entity?
Chosen answer: The Ghost is your spirit. In the end yes, they both merge,making a new entity, not just a human/cyborg and an AI, but a complete new entity - the whole is more than the sum of the parts.
