A long time ago, I discovered I was lactose intolerant. However, I was sure that this diagnosis could not be true. So I continued to drink milk and eat ice cream and cheese. Naturally, I continued to get sick. However, I always made up various excuses for why I was getting sick. I refused to believe that I was lactose intolerant. One day I realized I could not deny it any longer. Even though I truly believed I wasn’t lactose intolerance, the reality of the situation was that I was lactose intolerant. It is often said that we only believe what we want to believe. We choose to see and hear only certain ideas and opinions, while blocking out all other ideas that are unfavorable to us. Memento explores the ramifications of this wishful thinking by illustrating the devastating effects on a man who literally lives his life only believing what he wants to believe.
Leonard, the main character, has short-term amnesia. Therefore, he keeps a physical record of every “fact” he wants to remember. Unfortunately, he wanted to believe that Teddy, an undercover cop, was lying, so he recorded Teddy to be a liar. As a result of believing that Teddy was a liar, Leonard based many of his decisions upon this knowledge, which led Leonard in a downward spiraling path leading to the death of Teddy. This murder of Teddy occurred because Leonard actually fooled himself into believing Teddy was a liar.
Our minds are so powerful that, sometimes, when we tell ourselves to believe in things that aren’t true, we actually start believing them. While Leonard is an extreme example of this phenomenon, he effectively demonstrates how easily our brains can accept falsehoods as truths. The bad consequences occur when we begin acting upon this false notion of truth, like when I continued to consume dairy, which was detrimental to my health. As this movie demonstrates, the ability of the mind to fool itself is quite powerful.
