Editing Strange loop (section)

== Strangeness ==
The "strangeness" of a strange loop comes from the brain's perception, because the brain categorizes its input in a small number of "symbols" (by which Hofstadter means groups of neurons standing for something in the outside world). So the difference between the video-feedback loop and the brain's strange loops, is that while the former converts light to the same pattern on a screen, the latter categorizes a pattern and outputs its "essence", so that as the brain gets closer and closer to its "essence", it goes further down its strange loop.<ref name="Hofstadter">{{cite book|last=Hofstadter|first=Douglas|title=I Am A Strange Loop|year=2007|publisher=Basic Books |isbn=978-0-465-03078-1|url-access=registration|url=https://archive.org/details/iamstrangeloop00hofs}}</ref>
