The Conscious and Unconscious
According to Sigmund Freud our behaviors and actions are controlled by two zones of our brain, the conscious zone and the unconscious zone. He says that most of our actions are caused by the unconscious part of our brain, which is about 90% of the total brain, while the conscious part plays a very little role in influencing our behaviors. He gives an example of an iceberg floating in the sea. He says that the peak, that part which is above the water level, of the iceberg is the conscious zone, while the bottom of the iceberg, that part which is under the water level, is the unconscious zone of our brain. The third part of our brain is the preconscious zone which acts like a buffer zone between these two zones. Freud says that those things which are present in the unconscious zone are not easily accessible to our mind, while those in the conscious zone are always available to our mind. We are unaware of those things which are present in the unconscious zone.
We perform many activities and experience various things in our daily life. All these things affect our brain directly or indirectly, and they are stored in our memory. Some of these things are very embarrassing and make us unhappy. So we try to forget them and send them to the unconscious zone of our brain to keep ourselves cool and calm. Freud called this process Repression. But it is not always true. Sometimes they suddenly enter into the conscious zone of our brain and influence our behavior. Similarly, we make many mistakes in our daily conversations. Freud says that these slips of tongue are not due to chance but they are the results of those factors which are present in the unconscious zone of our brain.
