Jean-Jacques Rousseau, Reveries of the Solitary Walker

"Entirely taken up by the present, I could remember nothing; I had no distinct notion of myself as a person, nor had I the least idea of what had just happened to me. I did not know who I was, nor where I was; I felt neither pain, fear, nor anxiety. I watched my blood flowing as I might have watched a stream, without even thinking that the blood had anything to do with me. I felt throughout my whole being such a wonderful calm, that whenever I recall this feeling I can find nothing to compare with it in all the pleasures that stir our lives."
