"The Danger of a Single Story"

There is a very obvious limitation of two dimensions. You can see left and right, and forwards and backwards, but there is just no way of looking up and down. Take a two dimensional creature: he has no idea of a third dimension. He is perfectly content with his two dimensions. He cannot identify the limitations of isolation in a single plane because he does not know any differently. As this creature grows up, he begins to hear frightening rumors of a third dimension through his other two dimensional friends. They do not know precisely what it is, only that it is much different and horrifying. The third dimension haunts the two dimensional creatures.  They continue to express their fear, and live in constant paranoia of one day coming into contact with this new dimension. Little do they know, the day will never come. The two dimensional creatures have built up the third dimension to be one of fear, and monstrosity.

It is too easy to say that the two dimensional creatures are narrow minded, and only following a 'single story.' They do not have the access to the real facts. They have neither witnessed the third dimension for themselves, nor come into direct contact with someone who has. The two dimensional creatures cannot deny entirely the existence of the third dimension. So what can they do to avoid the single story?
