Why is it that we can read the above paragraph?  Our brains create shortcuts in order to make sense of the world around us.  What our brains see is not necessarily what our eyes see.  In the above paragraph because our brain expects the sentences to make sense, it fixes mistakes and thus we are able to read the apparent nonsense.  Our brain guesses at what it's seeing.

 What do you see above?  Does your mind fill in the partial lines and see a black outlined triangle or use the angles in the partial circles to see an upside down triangle?  Is that what's really there?  No, your mind is creating shortcuts to fulfill our expectations.
