Lies can be used for good in many things.
An example of lies being used for good was D-day. The opposing forces of the Nazi Party fed false information to them, so they would remove soldiers from one spot and move them somewhere else. This lead to an easy invasion by the Allies because there was little to no military units. This was a crushing blow the Nazi Party which lead to their downfall. This lie caused lots of Allied lives to be saved and the liberation of Germany from the Nazi Party. Lies can easily make people happy even if they think you’re lying to them. An example of this would be when people are having a “fat day” where they feel unattractive and you boost their self-esteem and confidence by telling them that they look absolutely beautiful. They may know you’re lying to them but either way it makes them feel much better about themselves. It let’s them have the strength to take on the day with a smile instead of a frown. It may not be the most convincing and long lasting lie but for a moment they’ll be
happy. If there was a world that was in a state of constant truth I would absolutely not want to live in that world. In that world there would be no one to trust to keep a secret or two. As soon as the secret is brought up everyone would know. I probably wouldn’t be emotionally affected in a world battle-hardened by truth but it’d be quite lonely keeping everything to yourself for as long as you can. Mr. Prest you mentioned that dating would be significantly faster and wouldn’t be a waste of time, but isn’t part of the fun the chase? The unknown is a lot more interesting than the known. The known has been explored hundreds of times but the unknown is untouched and that draws a lot of people towards it. In world of constant truth there would be no mysteries in society, only in the fields of science. Science is filled with wonder, but sometimes there’s nothing more interesting than a big juicy secret. Ultimately, a world in constant truth would be absolutely boring.
