"The Invention of Lying"

There is this movie called The Invention of Lying in which everyone in the world constantly tells the truth. The word 'lie' does not exist nor does anyone have an understanding of what a lie is. Well, just as you must have an up to have a down, you must have a lie to have the truth. To clarify, just as the world has no understanding of a lie, they also have no understanding of the truth. However, one day this man went into the bank to withdraw all of his money from his account, and the bank's system was down. So, the bank teller asks the man how much money was in his account, so she could withdraw it out for me. She explains that she can't access his account because the system is still down, so he would just have to tell her. Suddenly, something strange happens. The man develops the idea to tell the lady that there is more money in the account than it actual is, and he does. This is a strange thing that the man has just done, and he is unable to explain it. Exactly when he tells the lady how much he wants to withdraw, the bank's system comes back up, and the lady notices that the amount of money that the man asked for was not present in his account. The lady informs the man of this problem and apologizes for the bank's mistake (which wasn't the bank's mistake at all), and the teller withdraws the amount of money that the man originally asked for because, again, everybody tells the truth, so she did not even begin to understand that the man was telling the first lie in the world. Now, the man continues to lie and fabricates a story about a man in the sky that controls the universe. The entire world is in 'aw' about this man in the sky and wants to know more. Well, of course the lies that the man tells are parallel to christianity, and everyone listens and obeys these supposed lies.

Now, Montaigne claims that society should only live their lives through truth and reality. Imagine if we lived in a world like in The Invention of Lying. Would the world be a better place and stress-free, or would it be a painful world to live in because people are constantly revealing their 'true' feelings towards one another, which can lead to comments like 'you're fat,' 'you're ugly,' or 'I hate you?'
