While modern humans often admit there is no original thought which hasn't been previously formulated by another person, I tend to think each of our perspectives are unique. In further conversation on this topic with Cog, his reply was "perhaps, but how different are those perspectives from one another?"
I contend if each person is living life while narrating the meaning of all experiences and sensory input according to their own understanding and emotional makeup, then no two lives can really be the same no matter how similar the programming.
No where is individuality more evident than in a power hungry nanny state seeking to strip creativity and critical thinking from it's population in order to bring everyone into a manageable group-think. For a fascinating perspective on the endurance of the individual perspective, please read: The Last Individual In Europe - a short story.
