Carl Rodgers was the follower of Freud. He believed in the views of Freud but his points of view were of self were simpler as the views of Freud. Rodgers thought that "mental health" was the natural development of life. His theory is built on the single force of life. He calls it the actualizing tendency. His understanding of single force of life can be defined as built-in incentive which is presented in every form of life and serves to develop its impending to the fullest possible degree. Rodgers is sure that humans want to do everything only the best of their existence, but if they do not manage to do this, it does not mean the lack of desire. There are not many differences in the teachings of Freud and Rodgers. The last said that need can be valid to all organisms. He spoke of people as of creatures of nature and when they created society it generated its own life. There was one more pupil of Freud, Carl Jung who followed the ideas of Freud very closely. Like his mentor, Jung believed that human inner self can be divided into three parts, but the difference between them is more distinct. According to him, the inner self of person has one addition that unites all humans together as a species having common and different things. This addition was named "collective unconscious" and it can be best described as "physic inheritance" he calls it as reservoir of some knowledge and inborn experience. People are born with them, but never conscious of them. He states that they influence emotions and decisions and it is impossible to know about them directly, as they only influence us. Present day psychologists which follow this theory name the phenomenon of near death and apply it as an example of physic inheritance.
