We all have heard it claimed that 13 is an 'unlucky number.' Indeed, there are many hotels in America that for this very reason claim not to have a 13th floor, in the sense that there is no button bearing the label '13' in their elevators (I recently stayed in one in New York, in fact).

Douglas HofstadterWe create an image of who we are inside our self. The image then becomes very deeply entrenched, and it becomes the thing that we attribute responsibility to - we say "I", "I" did this because "I" wanted to, because "I" am a good person or because "I" am a bad person. The loop is the fact that we represent our selves, our desires, hopes, dreads and dreams: it is the way in which we conceive of ourselves, rather than the way we conceive of Mount Everest or of a tree. And I say it exists entirely in the loop: the self is an hallucination hallucinated by an hallucination.
