I feel almost as if I had been born in a vacuum of innocence, and then had to come to terms with the fact that actually, I was born into the middle of history - the rather grimy normality of the 70s, which did, indeed, retain some traces of human innocence, but were also girded about by the demons of experience.
You might call this innocence. I had a sense of another world that had not been spoken of to me.
I suppose I could say that to be interested in innocence already suggests a remove from innocence, perhaps a longing for something that is lost.
If there is innocence on Earth again, I tend to imagine it in more [Henry David]Thoreau sort of terms.
