Abstract

This article entitled" "I" as most important motivation of Human being" want to consider the main source of all human behaviors. This article aims to answer the question that what causes values or anti-values and also new ideas, giving meanings and human attitudes to be created? Where is the source of human activity and inactivity? Despite the diversity of human behaviors and actions of various origins it seems that one and same origin for all of them can be considered and it is self-preservation. Of course, self-preservation is a general principle for all living creatures.Calling it "self-preservation" in this writing, therefore I say that it is most important motivation of human behavior (whether active or passive behavior). Therefore, "I" is present everywhere with us and that is the creator of happiness and sadness. Thus, all our social and cultural behaviors in our society emanate from it and there will be always "selfishness" in society.
