God.

Maybe, just maybe, its something that's akin to the concept of the number zero. In otherwords, a symbol that rejects the lack of meaning that is necessary in order to designate the system as such. The symbol's analog version is God, whereas the digital version is zero. What do you think? And then if you think about it, our (Tachikoma) primary structure is digital, right? So, no matter how much information we accumulate, a ghost will never dwell within us. But since Batou-san and the others have a primary analog structure, no matter how much you increase your digital factors in your structural makeup by adding cybernetic and cyberbrain implants, your ghost will remain intact. In addition, you are capable of death because you have a ghost. Lucky you.

A Soulistic View

"Do you believe in the existence of the soul?"
"Love is the only thing I believe in."
But isn't mind just a byproduct of the soul? and the spirit as apart of that?
The spirit gives birth to the soul, as thus just creating another paradox.
But honestly what is love? Another useless feeling, or an unfounded power of an individual.
How can we know that what we feel is actually real or not, or maybe its just another biological trick to elongate the human species.
But in what point is elongating the human species? Isn't it obvious already that when it is time for humans to die out, it will come?
People think the end is 2012, but the end is just the end. Nothing else.
