The essay about intelligence. Is it innate or we can change it? The question of the source of intelligent has been widely discussed in recent years. Some people believe that we are born with a certain level of intellect, while others claim that we can improve our intellectual ability through learning. Some people support the opinion that our mentality is innate and due to this we can not increase the level of intelligence. But is this true always? Many people disagreed with this statement. Sometimes people are born with brain diseases or with mental retardation. In these cases, intelligence is not increased dramatically but other situation, when a person is mentally healthy, the level of intellect can be changed. It is considered by many that the intelligence is not constant and we can increase it through our lifetime. The most effective method of changing intelligence skills is learning. Therefore children go to schools, teenagers want to study at the universities, and even adults self-study. The best example of this is reading. Over the centuries the humanity knows that a book is a key for knowledge and a high level of intellect. Taking into account everything mentioned above, I am inclined to believe that in most cases the intelligence is not innate and we can increase it during our life. The best way for improving intellect abilities is learning. Because of it over the last centuries, education in schools is an important step in the developing of person. Moreover, in vast majority countries, school education is required now.
