The way we interpret the world and ourselves is reflected in what we do in this world. Sigmund Freud’s Three Case Histories, topic of the obsession neurosis, or the rat man is a great example of a situation that can cause a person to act differently. Freud develops techniques of interpreting the rat man by using patient’s stories and explanation. An obsessed person interprets the world differently than a non obsessed person.
Obsession is an idea or thought that continually preoccupies or intrudes on a person's mind. In the case the patient is presented with obsessive thoughts and behaviors that Freud felt would compel the patient to carry out. Freud theorized that these obsessive ideas and similar thoughts were produced by conflicts consisting of the combination of loving and aggressive impulses relating to the people concerned.
People have obsessions with love and fear but always living in fear will drive a person crazy. Always worrying about the deaths of loved ones would haunt just about anyone. In the case of the rat man he was obsessed with the cruel method the military used for torture. The method included rats that are trapped and the only escape is to borrow through a person’s anus. The rat man would obsess about the torture happening to his father or fiancé. A person’s fear controls the view of the world and can change what they do in this world.
I believe that people have a natural instinct of fear. Evolutionarily people have fears for spiders due to the poisonous factors. The people who didn’t have the fear died from the spider bite and the people who did have the fear survived. Fear is only natural but obsessions leads to irrationality. A person with obsession interprets the world and themselves differently and acts differently in the world.
